More than the EPC rating
HeatWise doesn’t calculate from the A–G rating alone. We load the useful home details behind the certificate, then show them to you before anything is calculated.
Nothing has been calculated yet. Next, you’ll see what the EPC says about the home and can update anything that is missing or has changed.

What the certificate says
We translated the relevant entries into plain English. Open any item to see the certificate wording or change what will be carried forward.
What this evidence will do
Evidence check — no planning figures yet. Nothing has been sized or priced on this screen. System size and cost ranges appear only after you continue into the project questions.
Project details for your plan
We’ve carried forward your home’s size, fabric and current heating from its energy record and your checks. We only need the project details below to refine system paths and figures.
Still no system size or installed-cost range on this screen — those appear after you build the Passport.
