Rules on letting this property
Properties can be rented if they have an energy rating from A to E.
If the property is rated F or G, it cannot be let, unless an exemption has been registered. You can read
guidance for landlords on the regulations and exemptions.
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)
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.
Cavity wall, as built, insulated (assumed)
Flat, insulated (assumed)
Fully double glazed
Boiler and radiators, mains gas
Main heating control
Programmer, room thermostat and TRVs
From main system
Low energy lighting in 74% of fixed outlets

Primary energy use
The primary energy use for this property per year is 134 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 C. 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
1.5 tonnes of CO2
This property’s potential production
1.5 tonnes of CO2
By making the
recommended changes, you could reduce this property’s CO2 emissions by 0.0 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.
Improve this property’s energy performance
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 C (77) to C (78).
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.

Estimated energy use and potential savings
Estimated yearly energy cost for this property
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.
The potential saving shows how much money you could save if you
complete each recommended step in order.

Type of assessment
Show information about the RdSAP
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.
