How it works
No sign-up, no phone number, no sales calls. Just your postcode and 3 minutes.
We look up your home's energy certificate automatically. No manual entry needed.
We pre-fill what we can from your certificate. You just confirm the details look right.
We show you what size heat pump you need, what it will cost, and how much you could save on your bills.
Get quotes from approved installers near you: we never sell your details.
Just enter your postcode and we pull up your home's energy certificate automatically.
The government's £7,500 grant is automatically taken off your estimate. Oil and LPG homes now get £9,000.
We compare the 5 cheapest electricity tariffs for heat pump owners side by side: choosing the right one could save you hundreds a year.
We never ask for your name, email or phone number. Your results stay private: no account needed.
Our calculation uses the same method professional installers use: so you get a realistic estimate, not a guess.
If you're a tenant, you can send your results to your landlord in one click: with all the numbers they need to make a decision.
Why use this tool?
Most heat pump tools are owned by companies trying to sell you something. We're independent: and we show you everything upfront, with no strings attached.
