Grants and rules for heat pumps in England
Homes in Blackburn 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.

Designing for Blackburn's winters
On the shortest day Blackburn gets only about 7 hours 25 minutes of daylight and the noon sun sits around 13° above the horizon. Northern winters tend to be longer, so a well-designed, efficient system matters more here because it runs for more of the year.
Heat pumps in Blackburn: questions
How long does installation take in Blackburn?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Blackburn home states the expected time.
How long does a heat pump survey take in Blackburn?
A home survey in Blackburn 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.
Do I need new radiators for a heat pump in Blackburn?
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 Blackburn home gives a room-by-room list.
Where would the outdoor unit go on a Blackburn house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Blackburn home.
