Most people already have an Energy Performance Certificate (EPC) for their house. For houses over 10 years old, these certificates are produced by a Domestic Energy Assessor using a method called RdSAP.

The EPC and the data behind it is stored in a government database for public access.

We use similar data to a tool licensed from Parity Projects Ltd to update information about the home and assess a whole range of possible energy efficiency measures that could be applied.

The software tool calculates the energy saving and CO2 emissions reduction associated with each and enables us to assemble a whole-house retrofit plan for you that, if fully applied, would make your home nearly zero carbon.

If applicable, we add to this a few other options not in the software that are good value for money that you may want to do as well or instead. We also provide a commentary that describes how the measures should be designed to improve your home and avoid the dangers of inadequate ventilation and excess humidity.

We offer a fixed price service to develop the whole house retrofit plan including the outputs shown in the image opposite.
