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 Blackheath 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.

Short winter days in Blackheath and what they mean
On the shortest day Blackheath gets about 7 hours 50 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.
Heat pumps in Blackheath: questions
Can you service a heat pump in Blackheath that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Blackheath, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Blackheath home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Blackheath home.
How long does installation take in Blackheath?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Blackheath home states the expected time.
Do you cover Lewisham as well as Blackheath?
Yes. We arrange surveys and installation in Lewisham, which is about a mile south-west of Blackheath, and across Greater London.
