This is a Predicted Energy Assessment for a property which is not yet complete. It includes a predicted energyrating which might not represent the final energy rating of the property on completion. Once the property iscompleted, an Energy Performance Certificate is required providing information about the energy performanceof the completed property.

Energy performance has been assessed using the SAP 2012 methodology and is rated in terms of the energyuse per square metre of floor area, energy efficiency based on fuel costs and environmental impact based oncarbon dioxide (CO2) emissions.

Very energy efficient - lower running costs

Not energy efficient - higher running costs

England & Wales EU Directive2002/91/EC

The energy efficiency rating is a measure of theoverall efficiency of a home. The higher the ratingthe more energy efficient the home is and thelower the fuel bills are likely to be.

Very environmentally friendly - lower CO2 emissions

Not environmentally friendly - higher CO2 emissions

The environmental impact rating is a measure of ahome's impact on the environment in terms ofcarbon dioxide (CO2) emissions. The higher therating the less impact it has on the environment.
