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 Northampton quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

Designing for Northampton's winters
Northampton has about 7 hours 42 minutes of daylight at midwinter and 16 hours 47 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.
Heat pumps in Northampton: questions
How long does a heat pump survey take in Northampton?
A home survey in Northampton usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
How soon can you survey a home in Northampton?
Survey dates depend on how busy installers are in Northamptonshire. We offer the next available dates when you enquire and confirm them in writing.
Can you service a heat pump in Northampton that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Northampton, whoever fitted them. Tell us the make and model when you book.
Do I need new radiators for a heat pump in Northampton?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Northampton home gives a room-by-room list.
