Payback visualiser

When does this upgrade pay itself back?

Plug in three numbers: current bill, measure, install cost. Then see year-by-year cumulative savings.

We use nominal figures (no assumed energy-price inflation). Real life usually pays back faster. We’d rather under-promise.

Combined gas + electricity. Annual figure, before any upgrade.

Pick the one you want to model. Run again to compare.

What you actually pay out of pocket. For a heat pump under the Boiler Upgrade Scheme, deduct £7,500 first (or £9,000 if your home is off the gas grid, on oil or LPG, for installs commissioned 21 July 2026 to 31 March 2027).
