Grants and rules for heat pumps in England
Homes in Milton Keynes can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
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.

Short winter days in Milton Keynes and what they mean

Heat pumps in Milton Keynes: questions
Can you service a heat pump in Milton Keynes that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Milton Keynes, whoever fitted them. Tell us the make and model when you book.
Do you cover Bletchley as well as Milton Keynes?
Yes. We arrange surveys and installation in Bletchley, which is about 3 miles south of Milton Keynes, and across Buckinghamshire.
How soon can you survey a home in Milton Keynes?
Survey dates depend on how busy installers are in Buckinghamshire. We offer the next available dates when you enquire and confirm them in writing.
Do I need new radiators for a heat pump in Milton Keynes?
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 Milton Keynes home gives a room-by-room list.
