The graph shows this property’s current and potential energy efficiency.
Properties are given a rating from A (most efficient) to G (least efficient).
Properties are also given a score. The higher the number the lower your fuel bills are likely to be.
For properties in England and Wales:
the average energy rating is D
the average energy score is 60
Breakdown of property’s energy performance
This section shows the energy performance for features of this property. The assessment does not consider the condition of a feature and how well it is working.
Each feature is assessed as one of the following:
very good (most efficient)
good
average
poor
very poor (least efficient)
When the description says “assumed”, it means that the feature could not be inspected and an assumption has been made based on the property’s age and type.

Primary energy use
The primary energy use for this property per year is 342 kilowatt hours per square metre (kWh/m2).
What is primary energy use?
Primary energy use is a measure of the energy required for lighting, heating and hot water in a property. The calculation includes:
the efficiency of the property’s heating system
power station efficiency for electricity
the energy used to produce the fuel and deliver it to the property
Environmental impact of this property
This property’s current environmental impact rating is E. It has the potential to be C.
Properties are rated in a scale from A to G based on how much carbon dioxide (CO2) they produce.
Properties with an A rating produce less CO2 than G rated properties.
An average household produces
6 tonnes of CO2
This property produces
4.7 tonnes of CO2
This property’s potential production
2.6 tonnes of CO2
By making the recommended changes, you could reduce this property’s CO2 emissions by 2.1 tonnes per year. This will help to protect the environment.
Environmental impact ratings are based on assumptions about average occupancy and energy use. They may not reflect how energy is consumed by the people living at the property.

By following our step by step recommendations you could reduce this property’s energy use and potentially save money.
Carrying out these changes in order will improve the property’s energy rating and score from D (57) to C (77).
Do I need to follow these steps in order?
Yes. Each step builds on the one before it so you can save the most energy.
For example, it’s more energy efficient to insulate your home before you buy a new boiler. A well insulated home will lose less heat so you do not have to run your boiler as often.
Step 1: 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).

Step 2: 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).

Step 3: Low energy lighting
Replacement of traditional light bulbs with energy saving recommended ones will reduce lighting costs over the lifetime of the bulb, and they last up to 12 times longer than ordinary light bulbs. Also consider selecting low energy light fittings when redecorating; contact the Lighting Association for your nearest stockist of Domestic Energy Efficient Lighting Scheme fittings.

Step 4: 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 as well as the thermostatic radiator valves, to enable the boiler to switch off when no heat is required.

Step 5: Band A 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, 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). Building Regulations apply to this work, so your local authority building control department should be informed, unless the installer is registered with a competent persons scheme?, and can therefore self-certify the work for Building Regulation compliance. Ask a qualified heating engineer to explain the options.

Step 6: Solar water heating
A solar water heating panel, usually fixed to the roof, uses the sun to pre-heat the hot water supply. This will significantly reduce the demand on the heating system to provide hot water and hence save fuel and money. The Solar Trade Association has up-to-date information on local installers and any grant that may be available.

Step 7: Solar photovoltaic (PV) panels
A solar PV system is one which converts light directly into electricity via panels placed on the roof with no waste and no emissions. This electricity is used throughout the home in the same way as the electricity purchased from an energy supplier. The British Photovoltaic Association has up-to-date information on local installers who are qualified electricians and on any grant that may be available. Planning restrictions may apply in certain neighbourhoods and you should check this with the local authority. Building Regulations apply to this work, so your local authority building control department should be informed, unless the installer is appropriately qualified and registered as such with a competent persons scheme?, and can therefore self-certify the work for Building Regulation compliance.
The estimated cost shows how much the average household would spend in this property for heating, lighting and hot water. It is not based on how energy is used by the people living at the property.
RdSAP (Reduced data Standard Assessment Procedure) is a method used to assess and compare the energy and environmental performance of properties in the UK. It uses a site visit and survey of the property to calculate energy performance.
This type of assessment can be carried out on properties built before 1 April 2008 in England and Wales, and 30 September 2008 in Northern Ireland. It can also be used for newer properties, as long as they have a previous SAP assessment, which uses detailed information about the property’s construction to calculate energy performance.
