This document is a Predicted Energy Assessment for properties marketed when they are incomplete. Itincludes a predicted energy rating which might not represent the final energy rating of the property oncompletion. Once the property is completed, this rating will be updated and an official Energy PerformanceCertificate will be created for the property. This will include more detailed information about the energyperformance of the completed property.

The energy performance has been assessed using the Government approved SAP2012 methodology andis rated in terms of the energy use per square meter of floor area; the energy efficiency is based on fuelcosts and the environmental impact is based on carbon dioxide (CO2) emissions.

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

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.
