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).

How it works
Three steps to a clear answer
No obligation, no pushy follow-ups, no fees from us — ever.
Eligibility check
Owner-occupier or private landlord, property in England or Wales, valid EPC, no outstanding loft or cavity insulation recommendations on the EPC. Most homes qualify — we check yours in 60 seconds.
Match with MCS installer
The grant must go through an Ofgem-approved, MCS-certified installer. We connect you with one (or up to three for comparison) who handles the full BUS application on your behalf.
Grant deducted from quote
The £7,500 is paid by Ofgem directly to your installer, who deducts it from the price you pay. No application fee, no upfront grant payment from you, no complex paperwork.
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.
