80 mm jacket Insulate hot water cylinder with 80 mm jacket Hot water cylinder insulation Installing an 80 mm thick cylinder jacket around the hot water cylinder will help to maintain the water at the required temperature; this will reduce the amount of energy used and lower fuel bills. A cylinder jacket is a layer of insulation that is fitted around the hot water cylinder. The jacket should be fitted over any thermostat clamped to the cylinder. Hot water pipes from the hot water cylinder should also be insulated, using pre-formed pipe insulation of up to 50 mm thickness, or to suit the space available, for as far as they can be accessed to reduce losses in summer. All these materials can be purchased from DIY stores and installed by a competent DIY enthusiast. 2 Increase hot water cylinder insulation Increase hot water cylinder insulation Hot water cylinder insulation Increasing the thickness of existing insulation around the hot water cylinder will help to maintain the water at the required temperature; this will reduce the amount of energy used and lower fuel bills. An additional cylinder jacket or other suitable insulation layer can be used. The insulation should be fitted over any thermostat clamped to the cylinder. Hot water pipes from the hot water cylinder should also be insulated, using pre-formed pipe insulation of up to 50 mm thickness, or to suit the space available, for as far as they can be accessed to reduce losses in summer. All these materials can be purchased from DIY stores and installed by a competent DIY enthusiast. 3 Add additional 80 mm jacket to hot water cylinder Add additional 80 mm jacket to hot water cylinder Hot water cylinder insulation Increasing the thickness of existing insulation by adding an 80 mm cylinder jacket around the hot water cylinder will help maintain the water at the required temperature; this will reduce the amount of energy used and lower fuel bills. The jacket should be fitted over the top of the existing foam insulation and over any thermostat clamped to the cylinder. Hot water pipes from the hot water cylinder should also be insulated, using pre-formed pipe insulation of up to 50 mm thickness, or to suit the space available, for as far as they can be accessed to reduce losses in summer. All these materials can be purchased from DIY stores and installed by a competent DIY enthusiast. 4 Hot water cylinder thermostat Hot water cylinder thermostat Cylinder thermostat A hot water cylinder thermostat enables the boiler to switch off when the water in the cylinder reaches the required temperature; this minimises the amount of energy that is used and lowers fuel bills. The thermostat is a temperature sensor that sends a signal to the boiler when the required temperature is reached. To be fully effective it needs to be sited in the correct position and hard wired in place, so it should be installed by a competent plumber or heating engineer. Building regulations apply to this work, so it is best to check with your local authority building standards department whether a building warrant will be required. 5 Increase loft insulation to 270 mm Increase loft insulation to 270 mm Loft insulation Loft insulation laid in the loft space or between roof rafters to a depth of at least 270 mm will significantly reduce heat loss through the roof; this will improve levels of comfort, reduce energy use and lower fuel bills. Insulation should not be placed below any cold water storage tank, any such tank should also be insulated on its sides and top, and there should be boarding on battens over the insulation to provide safe access between the loft hatch and the cold water tank. The insulation can be installed by professional contractors but also by a capable DIY enthusiast. Loose granules may be used instead of insulation quilt; this form of loft insulation can be blown into place and can be useful where access is difficult. The loft space must have adequate ventilation to prevent dampness; seek advice about this if unsure. Further information about loft insulation and details of local contractors can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk). 6 Cavity wall insulation Cavity wall insulation Cavity wall insulation Cavity wall insulation, to fill the gap between the inner and outer layers of external walls with an insulating material, reduces heat loss; this will improve levels of comfort, reduce energy use and lower fuel bills. The insulation material is pumped into the gap through small holes that are drilled into the outer walls, and the holes are made good afterwards. As specialist machinery is used to fill the cavity, a professional installation company should carry out this work, and they should carry out a thorough survey before commencing work to ensure that this type of insulation is suitable for this home and its exposure. They should also provide a guarantee for the work and handle any building standards issues. Further information about cavity wall insulation and details of local installers can be obtained from the Building Standards Division’s section of the Scottish Government website (www.scotland.gov.uk/Topics/Built-Environment/Building/Building-standards/publications/pubguide/cavitywallinsul) or the National Insulation Association (www.nationalinsulationassociation.org.uk). 7 Internal or external wall insulation Internal or external wall insulation Internal or external wall insulation Internal or external wall insulation involves adding a layer of insulation to either the inside or the outside surface of the external walls, which reduces heat loss and lowers fuel bills. As it is more expensive than cavity wall insulation it is only recommended for walls without a cavity, or where for technical reasons a cavity cannot be filled. Internal insulation, known as dry-lining, is where a layer of insulation is fixed to the inside surface of external walls; this type of insulation is best applied when rooms require redecorating. External solid wall insulation is the application of an insulant and a weather-protective finish to the outside of the wall. This may improve the look of the home, particularly where existing brickwork or rendering is poor, and will provide long-lasting weather protection. Further information can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk). It should be noted that planning permission might be required and that building regulations apply to this work so it is best to check with your local authority whether a building warrant or planning permission will be required. 8 Replace single glazed windows with low-E double glazed windows Double glazed windows Double glazed windows Double glazing is the term given to a system where two panes of glass are made up into a sealed unit. Replacing existing single-glazed windows with double-glazed windows will improve comfort in the home by reducing draughts and cold spots near windows. Double-glazed windows may also reduce noise, improve security and combat problems with condensation. Building regulations apply to this work and planning permission may also be required, so it is best to check with your local authority on what standards need to be met. A building warrant is not required if the windows comply with the current requirements. 9 Secondary glazing to single glazed windows Secondary glazing to single glazed windows Secondary glazing Secondary glazing is the addition of a second pane of glass inside the existing window. Adding secondary glazing will improve comfort in the home by reducing draughts and cold spots near windows. It may also reduce noise and combat problems with condensation. Installation can be carried out by a competent DIY enthusiast. Building regulations may apply to this work, so it is best to check this with your local authority building standards department. 10 Draughtproofing Draughtproofing Draughtproofing Fitting draughtproofing, strips of insulation around windows and doors, will improve the comfort in the home. A contractor can be employed but draughtproofing can be installed by a competent DIY enthusiast. 11 Upgrade heating controls Heating controls (programmer, thermostat, TRVs) Heating controls (programmer, room thermostat and thermostatic radiator valves) The heating system would benefit from a programmer and room thermostat to allow you to set the temperature and programme when you want the heating and hot water to switch on and off; this will reduce the amount of energy used and lower fuel bills. Thermostatic radiator valves should also be installed, to allow the temperature of each room to be controlled to suit individual needs, adding to comfort and reducing heating bills. For example, they can be set to be warmer in the living room and bathroom than in the bedrooms. Ask a competent heating engineer to install radiator valves and a fully pumped system with the pump and the boiler turned off by the room thermostat. Radiator valves should be fitted to every radiator except one – the radiator in the same room as the room thermostat. Remember the room thermostat is needed to enable the boiler to switch off when no heat is required, thermostatic radiator valves on their own do not turn the boiler off. Building regulations generally apply to this work and a building warrant may be required, so it is best to obtain advice from your local authority building standards department and from a qualified heating engineer. 12 Upgrade heating controls Heating controls (room thermostat and TRVs) Heating controls (room thermostat and thermostatic radiator valves) A room thermostat will increase the efficiency of the heating system by enabling the boiler to switch off when no heat is required; this will reduce the amount of energy used and lower fuel bills. Thermostatic radiator valves should also be installed, to allow the temperature of each room to be controlled to suit individual needs, adding to comfort and reducing heating bills provided internal doors are kept closed. For example, they can be set to be warmer in the living room and bathroom than in the bedrooms. Ask a competent heating engineer to install thermostatic radiator valves and a fully pumped system with the pump and the boiler turned off by the room thermostat. Thermostatic radiator valves should be fitted to every radiator except for the radiator in the same room as the room thermostat. Remember the room thermostat is needed to enable the boiler to switch off when no heat is required, thermostatic radiator valves on their own do not turn the boiler off. Building regulations generally apply to this work and a building warrant may be required, so it is best to obtain advice from your local authority building standards department and from a qualified heating engineer. 13 Upgrade heating controls Heating controls (TRVs) Heating controls (thermostatic radiator valves) Thermostatic radiator valves allow the temperature of each room to be controlled to suit individual needs, adding to comfort and reducing heating bills provided internal doors are kept closed. For example, they can be set to be warmer in the living room and bathroom than in the bedrooms. Ask a competent heating engineer to install thermostatic radiator valves. Thermostatic radiator valves should be fitted to every radiator except the radiator in the same room as the room thermostat. Remember the room thermostat is needed as well as the thermostatic radiator valves, to enable the boiler to switch off when no heat is required. Building regulations generally apply to this work, so it is best to obtain advice from your local authority building standards department and from a qualified heating engineer. 14 Upgrade heating controls Heating controls (room thermostat) Heating controls (room thermostat) The heating system should have a room thermostat to enable the boiler to switch off when no heat is required. A competent heating engineer should be asked to do this work. Insist that the thermostat switches off the boiler as well as the pump and that the thermostatic radiator valve is removed from any radiator in the same room as the thermostat. Building regulations generally apply to this work and a building warrant may be required, so it is best to obtain advice from your local authority building standards department and from a qualified heating engineer. 15 Upgrade heating controls Heating controls (programmer and TRVs) Heating controls (programmer and thermostatic radiator valves) The heating system would benefit from a programmer to provide better comfort through automatic control of the system. A modern programmer can provide different time programmes for heating and hot water, allowing different time periods to be set for each; seven-day programmers also allow different heating and/or hot water patterns to be set for weekdays and weekends and holidays. Thermostatic radiator valves should also be installed, to allow the temperature of each room to be controlled to suit individual needs, adding to comfort and reducing heating bills provided internal doors are kept closed. For example, they can be set to be warmer in the living room and bathroom than in the bedrooms. Ask a competent heating engineer to install thermostatic radiator valves and a fully pumped system with the pump and the boiler turned off by the room thermostat. Thermostatic radiator valves should be fitted to every radiator except for the radiator in the same room as the room thermostat. Remember the room thermostat is needed to enable the boiler to switch off when no heat is required, thermostatic radiator valves on their own do not turn the boiler off. Building regulations generally apply to this work and a building warrant may be required, so it is best to obtain advice from your local authority building standards department and from a qualified heating engineer. 16 Time and temperature zone control Heating controls (zone control) Heating controls (time and temperature zone control) The heating system controls should be improved so that both the temperature and time of heating can be set differently in separate areas of your house; this will reduce the amount of energy used and lower fuel bills. For example, it is possible to have cooler temperatures in the bedrooms than in the living room provided internal doors are kept closed, and to have a longer heating period for the living room. Building regulations generally apply to this work and a building warrant may be required, so it is best to obtain advice from your local authority building standards department and from a qualified heating engineer. 17 Upgrade heating controls Heating controls (programmer and thermostat) Heating controls (programmer and room thermostat) The warm air heating system would benefit from the addition of a programmer and room thermostat so that it switches off when no heat is required; this will reduce the amount of energy used and lower fuel bills. Insist that the thermostat switches off the warm air burner as well as the blower. A modern programmer can provide different time programmes for heating and hot water, allowing different time periods to be set for each; seven-day programmers also allow different heating patterns to be set for weekdays and weekends and holidays. Building regulations generally apply to this work and a building warrant may be required, so it is best to obtain advice from your local authority building standards department and from a qualified heating engineer. 18 Upgrade heating controls Heating controls (room thermostat) Heating controls (room thermostat) The warm air heating system in this home would benefit from the addition of a room thermostat so that it switches off when no heat is required; this will reduce the amount of energy used and lower fuel bills.

Building regulations generally apply to this work and a building warrant may be required, so it is best to obtain advice from your local authority building standards department and from a qualified heating engineer. 19 Solar water heating Solar water heating Solar water heating A solar water heating panel, usually fixed to the roof, uses the sun to pre-heat the hot water supply. This can significantly reduce the demand on the heating system to provide hot water and hence save fuel and money. Planning permission might be required, building regulations generally apply to this work and a building warrant may be required, so it is best to check these with your local authority. You could be eligible for Renewable Heat Incentive payments which could appreciably increase the savings beyond those shown on your EPC, provided that both the product and the installer are certified by the Microgeneration Certification Scheme (or equivalent). Details of local MCS installers are available at www.microgenerationcertification.org. 20 Replace boiler with new condensing boiler Condensing boiler Condensing boiler A condensing boiler is capable of much higher efficiencies than other types of boiler, meaning it will burn less fuel to heat this property. This improvement is most appropriate when the existing central heating boiler needs repair or replacement, however there may be exceptional circumstances making this impractical. Condensing boilers need a drain for the condensate which limits their location; remember this when considering remodelling the room containing the existing boiler even if the latter is to be retained for the time being (for example a kitchen makeover). Building regulations generally apply to this work and a building warrant may be required, so it is best to obtain advice from your local authority building standards department and from a qualified heating engineer. 22 Replace boiler with biomass boiler Biomass boiler Biomass boiler Modern boilers are cleaner burning and more efficient than the boiler in this home and cost less to run. A biomass boiler burns renewable fuel such as wood logs or pellets and therefore is less damaging to the environment. This improvement is most appropriate when the existing heating system needs repair or replacement. Building regulations generally apply to this work and a building warrant may be required, so it is best to check this with your local authority building standards department and also seek advice from a qualified heating engineer. Provisions under the Clean Air Act may determine if you can install such an appliance in your area so check this with your local authority. You could be eligible for Renewable Heat Incentive payments which could appreciably increase the savings beyond those shown on your EPC, provided that both the product and the installer are certified by the Microgeneration Certification Scheme (or equivalent). Details of local MCS installers are available at www.microgenerationcertification.org. 23 Wood pellet stove with boiler and radiators Biomass stove with boiler Biomass stove with boiler A closed-in solid fuel stove (also called a room heater) is about twice as efficient as an open fire. Modern heaters with glass doors are clean, easy to use and provide an attractive source of heating. A biomass boiler burns renewable fuel such as wood pellets and therefore is much less damaging to the environment. This improvement is most appropriate when the existing heating system needs repair or replacement. Building regulations generally apply to this work and a building warrant may be required, so it is best to check this with your local authority building standards department and also seek advice from a qualified heating engineer.

This improvement is most appropriate when the existing central heating warm air unit or hot water service needs repair or replacement. Building regulations may apply to this work, so it is best to obtain advice from your local authority building standards department and from a qualified heating engineer. 27 Change heating to gas condensing boiler Gas condensing boiler Gas condensing boiler Changing the heating to use a mains gas boiler that provides both space and water heating will save money, as mains gas is currently cheaper than the fuel being used at present. A condensing boiler is capable of much higher efficiencies than other types of boiler, meaning it will burn less fuel to heat the property, but there may be exceptional circumstances making this impractical. Condensing boilers need a drain for the condensate which limits their location; remember this when considering remodelling the room containing the existing boiler even if the latter is to be retained for the time being (for example a kitchen makeover). This improvement is most appropriate when the existing heating system needs repair or replacement. Building regulations generally apply to this work and a building warrant may be required, so it is best to obtain advice from your local authority building standards department and from a qualified heating engineer. It is also recommended to change the electricity tariff to standard tariff when off-peak is no longer used. 28 Condensing oil boiler with radiators Condensing oil boiler Condensing oil boiler Condensing boilers have a much higher efficiency than other types of heating appliance, meaning they will burn less fuel to heat the property. This option is best taken up when the present warm air unit requires repair or replacement. Building regulations generally apply to this work, and require replacement oil boilers to be of the condensing type, unless there are exceptional circumstances. As a building warrant may be required it is best to obtain advice from your local authority building standards department and from a qualified heating engineer. 29 Change heating to gas condensing boiler Gas condensing boiler Gas condensing boiler Changing the heating to use a mains gas boiler that provides both space and water heating will save money, as mains gas is currently cheaper than the fuel being used at present.

A cylinder jacket is a layer of insulation that is fitted around the hot water cylinder. The jacket should be fitted over any thermostat clamped to the cylinder. Hot water pipes from the hot water cylinder should also be insulated, using pre-formed pipe insulation of up to 50 mm thickness (or to suit the space available) for as far as they can be accessed to reduce losses in summer. All these materials can be purchased from DIY stores and installed by a competent DIY enthusiast. 2 Increase hot water cylinder insulation Hot water cylinder insulation Increasing the thickness of existing insulation around the hot water cylinder will help to maintain the water at the required temperature; this will reduce the amount of energy used and lower fuel bills. An additional cylinder jacket or other suitable insulation layer can be used. The insulation should be fitted over any thermostat clamped to the cylinder. Hot water pipes from the hot water cylinder should also be insulated, using pre-formed pipe insulation of up to 50 mm thickness (or to suit the space available) for as far as they can be accessed to reduce losses in summer. All these materials can be purchased from DIY stores and installed by a competent DIY enthusiast. 3 Add additional 80 mm jacket to hot water cylinder Hot water cylinder insulation Increasing the thickness of existing insulation by adding an 80 mm cylinder jacket around the hot water cylinder will help maintain the water at the required temperature; this will reduce the amount of energy used and lower fuel bills. The jacket should be fitted over the top of the existing foam insulation and over any thermostat clamped to the cylinder. Hot water pipes from the hot water cylinder should also be insulated, using pre-formed pipe insulation of up to 50 mm thickness (or to suit the space available) for as far as they can be accessed to reduce losses in summer. All these materials can be purchased from DIY stores and installed by a competent DIY enthusiast. 4 Hot water cylinder thermostat Cylinder thermostat A hot water cylinder thermostat enables the boiler to switch off when the water in the cylinder reaches the required temperature; this minimises the amount of energy that is used and lowers fuel bills. The thermostat is a temperature sensor that sends a signal to the boiler when the required temperature is reached. To be fully effective it needs to be sited in the correct position and hard wired in place, so it should be installed by a competent plumber or heating engineer. 5 Increase loft insulation to 270 mm Loft insulation Loft insulation laid in the loft space or between roof rafters to a depth of at least 270 mm will significantly reduce heat loss through the roof; this will improve levels of comfort, reduce energy use and lower fuel bills. Insulation should not be placed below any cold water storage tank; any such tank should also be insulated on its sides and top, and there should be boarding on battens over the insulation to provide safe access between the loft hatch and the cold water tank. The insulation can be installed by professional contractors but also by a capable DIY enthusiast. Loose granules may be used instead of insulation quilt; this form of loft insulation can be blown into place and can be useful where access is difficult. The loft space must have adequate ventilation to prevent dampness; seek advice about this if unsure (particularly if installing insulation between rafters because a vapour control layer and ventilation above the insulation are required). Further information about loft insulation and details of local contractors can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk). 6 Cavity wall insulation Cavity wall insulation Cavity wall insulation, to fill the gap between the inner and outer layers of external walls with an insulating material, reduces heat loss; this will improve levels of comfort, reduce energy use and lower fuel bills. The insulation material is pumped into the gap through small holes that are drilled into the outer walls, and the holes are made good afterwards. As specialist machinery is used to fill the cavity, a professional installation company should carry out this work, and they should carry out a thorough survey before commencing work to ensure that this type of insulation is suitable for this home. They should also provide a guarantee for the work and handle any building control issues. Further information about cavity wall insulation and details of local installers can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk). 7 50 mm internal or external wall insulation Internal or external wall insulation Solid wall insulation involves adding a layer of insulation to either the inside or the outside surface of the external walls, which reduces heat loss and lowers fuel bills. As it is more expensive than cavity wall insulation it is only recommended for walls without a cavity, or where for technical reasons a cavity cannot be filled. Internal insulation, known as dry-lining, is where a layer of insulation is fixed to the inside surface of external walls; this type of insulation is best applied when rooms require redecorating and can be installed by a competent DIY enthusiast. External solid wall insulation is the application of an insulant and a weather-protective finish to the outside of the wall. This may improve the look of the home, particularly where existing brickwork or rendering is poor, and will provide long-lasting weather protection. Further information can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk). 8 Replace single glazed windows with low-E double glazed windows Double glazed windows Double glazing is the term given to a system where two panes of glass are made up into a sealed unit. Replacing existing single-glazed windows with double-glazed windows will improve comfort in the home by reducing draughts and cold spots near windows. Double-glazed windows may also reduce noise, improve security and combat problems with condensation. 9 Secondary glazing to single glazed windows Secondary glazing Secondary glazing is the addition of a second pane of glass inside the existing window. Adding secondary glazing will improve comfort in the home by reducing draughts and cold spots near windows. It may also reduce noise and combat problems with condensation. Installation can be carried out by a competent DIY enthusiast. 10 Draught proof single-glazed windows Draught proofing Fitting draught proofing, strips of insulation around windows and doors, will improve the comfort in the home. A contractor can be employed but draught proofing can be installed by a competent DIY enthusiast. 11 Upgrade heating controls Heating controls (programmer, room thermostat and thermostatic radiator valves) The heating system would benefit from a programmer and room thermostat to enable the boiler to switch off when no heat is required; this will reduce the amount of energy used and lower fuel bills. Thermostatic radiator valves should also be installed, to allow the temperature of each room to be controlled to suit individual needs, adding to comfort and reducing heating bills. For example, they can be set to be warmer in the living room and bathroom than in the bedrooms. Ask a competent heating engineer to install thermostatic radiator valves and a fully pumped system with the pump and the boiler turned off by the room thermostat. Thermostatic radiator valves should be fitted to every radiator except one – the radiator in the same room as the room thermostat. Remember the room thermostat is needed as well as the thermostatic radiator valves, to enable the boiler to switch off when no heat is required. It is best to obtain advice from a qualified heating engineer. 12 Upgrade heating controls Heating controls (room thermostat and thermostatic radiator valves) A room thermostat will increase the efficiency of the heating system by enabling the boiler to switch off when no heat is required; this will reduce the amount of energy used and lower fuel bills.

It is best to obtain advice from a qualified heating engineer. 15 Upgrade heating controls Heating controls (programmer and thermostatic radiator valves) The heating system would benefit from a programmer to provide better comfort through automatic control of the system. A modern programmer can provide different time programmes for heating and hot water, allowing different time periods to be set for each; seven-day programmers also allow different heating and/or hot water patterns to be set for weekdays and weekends and holidays. Thermostatic radiator valves should also be installed, to allow the temperature of each room to be controlled to suit individual needs, adding to comfort and reducing heating bills provided internal doors are kept closed. For example, they can be set to be warmer in the living room and bathroom than in the bedrooms.

A dual-rate electricity supply is required to provide the off-peak electricity that these heaters use; this is easily obtained by contacting the energy supplier. Ask for a quotation for high heat retention heaters with automatic charge and output controls. A dual-immersion cylinder, which can be installed at the same time, will provide cheaper hot water than the system currently installed. As installations should be in accordance with the national wiring standards, only a qualified electrician should carry out the installation. Ask a qualified electrical heating engineer to explain the options, which might also include switching to other forms of electric heating. 62 High heat retention storage heaters High heat retention storage heaters Modern storage heaters are less expensive to run than the direct acting, on-peak heating system in the property.

Wall type does not correspond to options available in RdSAP The dwelling has a type of wall that is not included in the available options. The nearest equivalent type was used for the assessment. Mae gan yr annedd fath o wal sydd heb ei gynnwys yn yr opsiynau sydd ar gael. Defnyddiwyd y math cyfatebol agosaf ar gyfer yr asesiad. 4 4. Dwelling has a swimming pool The energy assessment for the dwelling does not include energy used to heat the swimming pool. Dydy asesiad ynni’r annedd ddim yn cynnwys yr ynni a gaiff ei ddefnyddio i wresogi’r pwll nofio. 5 5. Dwelling has micro-CHP not found in database The performance characteristics of the micro-CHP system in this dwelling are not known and default values were used for the assessment. Nid yw nodweddion perfformiad y system CHP meicro yn yr annedd hon yn hysbys a chafodd gwerthoedd diofyn eu defnyddio at yr asesiad. 6 6. Storage heater or dual immersion, and single electric meter A dual rate appliance(s) is present with a single-rate supply. A single-rate appliance has been used for the assessment. Changing the electricity tariff to an off-peak (dual rate) supply is likely to reduce fuel costs and improve the energy rating. Mae yma gyfarpar cyfradd ddeuol a chyflenwad cyfradd sengl. At ddibenion yr asesiad, cyfarpar cyfradd sengl sydd wedi’i ddefnyddio. Mae’n debyg y byddai newid y tariff trydan i gyflenwad heblaw’r cyflenwad oriau brig (cyfradd ddeuol) yn lleihau costau tanwydd ac yn gwella’r cyfraddiad ynni. 8 8. PVs or wind turbine present on the property (England, Wales or Scotland) The assessment does not include any feed-in tariffs that may be applicable to this property. Dydy’r asesiad ddim yn cynnwys unrhyw dariff dechreuol a allai fod yn gymwys ar gyfer yr eiddo hwn. 9 9. Two main heating systems and heating system upgrade is recommended As there is more than one heating system, you should seek professional advice on the most cost-effective option for upgrading the systems. Gan fod mwy nag un system wresogi, dylech ofyn am gyngor proffesiynol am y dewis mwyaf cost-effeithiol i uwchraddio’r systemau. 10 10. Dual electricity meter selected but there is also an electricity meter for standard tariff The assessment has been done on the basis of an off-peak electricity tariff. However some heating or hot water appliances may be on the standard domestic tariff. Cyflawnwyd yr asesiad ar sail y tariff trydan am gyfnodau tawel. Fodd bynnag, gall rhai mathau o offer gwresogi neu ddwr poeth fod ar y tariff domestig safonol. 11 11.
