In England and Wales, replacing electric heating is eligible for the Boiler Upgrade Scheme, so eligible owners can receive £7,500 towards an air-to-water system. Flats need extra thought about where the outdoor unit goes and who must agree to it, and for some an air-to-air system is a simpler fit.
For Northamptonshire homes with solid floors, the survey plans pipe routes through walls and ceilings to keep disruption predictable. Owners across Northamptonshire moving off storage heaters can arrange a survey in Northamptonshire that compares running costs on their real tariff. Installers in Northamptonshire work room by room, so you can stay in your home while radiators go in.
Who it suits
- Homes with storage heaters or panel heaters throughout
- Properties with an electric boiler and existing radiators
- Flats with a suitable wall, balcony or ground-floor space for the unit
- Bungalows and houses with suspended timber floors that make pipe runs easier
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your quote.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Replacing electric heating with a heat pump questions
Do I qualify for the Boiler Upgrade Scheme if I have electric heating?
In England and Wales, owners of existing homes replacing electric heating can qualify, provided the heat pump meets the home's full heating and hot water needs and the other scheme conditions are met. The grant is £7,500 for an air-to-water system. The scheme does not cover Scotland or Northern Ireland; Scotland has separate Home Energy Scotland funding.
Can I keep my electric immersion cylinder?
Usually not for heating by the heat pump, because a standard immersion cylinder has no coil, or one too small to take heat at low flow temperatures. A heat pump cylinder replaces it, often in the same cupboard, and keeps an immersion element as backup. If you choose an air-to-air system instead, which does not make hot water, the existing cylinder stays in use.
Can I replace storage heaters with a heat pump?
Yes. Storage heaters are removed and replaced with an air-to-water heat pump connected to new radiators or underfloor heating and a hot water cylinder. Because there is no existing wet system, pipework has to be run to each room, so the job is larger than a boiler swap. The survey plans pipe routes and radiator sizes before you receive a written quote.
How disruptive is fitting radiators in a home that has none?
More disruptive than a boiler swap, but planned. Floorboards are lifted to run pipes, some holes are drilled through walls and radiators are hung room by room. Rooms are worked on in a set order so you can keep living at home, and holes are made good, while redecoration is usually yours. The programme in your quote shows how long each stage typically takes.
