For homeowners · Retrofit ROI

Is it worth upgrading this home?

Enter the address. We use the EPC's own recommended improvements and modelled fuel costs to give you a verdict: how much retrofit would cost, how much it'd save a year, and how long that pays back. Plus the single cheapest quick win, if you're only doing one thing.

Enter both a postcode and at least three characters of the address (for example a house number and the start of the street) to look up the EPC.

This tool reports the EPC's own recommendations and modelled fuel costs. It is not a quote and not financial advice. Real-world install costs vary by contractor, by property, and by what's already been done. For a binding quote, get a retrofit assessor or contractor to visit the property.
