Energy efficiency chart This property’s current energy rating is C with a score of 80. It has a potential energy rating of C with a score of 80.

The graph shows this property’s current and potential energy rating.

Properties get a rating from A (best) to G (worst) and a score. The better the rating and score, the lower your energy 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

Features in this property

Features get a rating from very good to very poor, based on how energy efficient they are. Ratings are not based on how well features work or their condition.

Assumed ratings are based on the property's age and type. They are used for features the assessor could not inspect.

Walls Average thermal transmittance 0.21 W/m²K Very good
Roof Average thermal transmittance 0.15 W/m²K Good
Windows High performance glazing Very good
Main heating Electric underfloor heating Very poor
Main heating control Time and temperature zone control Very good
Hot water Electric immersion, standard tariff Very poor
Lighting Low energy lighting in all fixed outlets Very good
Air tightness Air permeability 4.6 m³/h.m² (as tested) Good
Floor (other premises below) N/A
Secondary heating None N/A

Low and zero carbon energy sources

Low and zero carbon energy sources release very little or no CO2. Installing these sources may help reduce energy bills as well as cutting carbon emissions. The following low or zero carbon energy sources are installed in this property:

  • Solar photovoltaics

Primary energy use

The primary energy use for this property per year is 86 kilowatt hours per square metre (kWh/m2).

About 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

How this affects your energy bills

An average household would need to spend £558 per year on heating, hot water and lighting in this property. These costs usually make up the majority of your energy bills.

You could save £0 per year if you complete the suggested steps for improving this property’s energy rating.

This is based on average costs in 2022 when this EPC was created. People living at the property may use different amounts of energy for heating, hot water and lighting.

Heating this property

Estimated energy needed in this property is:

  • 746 kWh per year for heating
  • 1,669 kWh per year for hot water

Environmental impact of this property

This property’s current environmental impact rating is B. It has the potential to be B.

Properties get a rating from A (best) to G (worst) on how much carbon dioxide (CO2) they produce each year. CO2 harms the environment.

Carbon emissions

An average household produces
6 tonnes of CO2
This property produces
1.0 tonnes of CO2
This property’s potential production
1.0 tonnes of CO2

You could improve this property’s CO2 emissions by making the suggested changes. This will help to protect the environment.

These ratings are based on assumptions about average occupancy and energy use. People living at the property may use different amounts of energy.

Changes you could make

The assessor did not make any recommendations for this property.

Simple Energy Advice has guidance on improving a property’s energy use.

Help paying for energy improvements
