Electric heating / storage heaters to air source heat pump
Typical annual saving: £900–£1,800. Estimated payback: 3–5 years (with grant). Off-gas-grid homes (oil, LPG, electric) typically see the fastest payback in the UK.

Switching from electric heating / storage heaters: what changes
Switching from electric heating (storage heaters, panel heaters, immersion-only hot water) to an air source heat pump delivers the largest absolute savings of any UK scenario. Direct electric heating runs at 100% efficiency (1 kWh in = 1 kWh out); a heat pump runs at 280–340%.
Annual savings of £900–£1,800 are typical, with payback as short as 3–5 years after the £7,500 BUS grant. Many storage- heater properties also benefit from time-of-use tariffs designed for heat pumps (Octopus Cosy, EDF Heat Pump).
Why act now
Why UK homeowners are switching
The Boiler Upgrade Scheme runs to 2028, energy prices remain volatile, and modern heat pumps work fine in British winters.

How it works
Three steps to a clear answer
No obligation, no pushy follow-ups, no fees from us — ever.
Free home survey
An MCS-certified installer visits to measure heat loss, check radiators, hot water cylinder space and existing pipework. Most surveys are free; complex retrofit cases sometimes require a paid heat-loss calculation, which the installer will quote upfront.
Written quote + grant
You receive a written, itemised quote — equipment, install labour, electrical work, commissioning, MCS certificate. The £7,500 BUS grant (England/Wales) is applied at the quote stage and paid by the installer to Ofgem on your behalf.
You decide — no pressure
Compare up to three quotes, ask questions, sleep on it. If you proceed, install typically takes 2–5 days depending on the size of the property and whether radiators need upgrading.
Common questions
Air source heat pump FAQs
Installed costs typically run £8,000 to £14,000 before grant for a normal home. Detached or larger properties can reach £16,000. After the £7,500 BUS grant in England & Wales, most homeowners pay £500–£8,500. Scotland's Home Energy Scotland scheme offers up to £15,000 in combined grant + interest-free loan, often making the heat pump cheaper than a like-for-like boiler replacement.

The £7,500 BUS grant runs to 2028 — there's no rush, but waiting another year on an old gas, oil or LPG boiler costs you running-cost savings every month. A free survey tells you whether the fit is straightforward, with zero commitment.
