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 Penzance 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 Penzance and what they mean
On the shortest day Penzance gets about 8 hours 03 minutes of daylight, and the winter sun reaches only around 16° 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 Penzance: questions
How long does a heat pump survey take in Penzance?
A home survey in Penzance 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 long does installation take in Penzance?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Penzance home states the expected time.
Do I need new radiators for a heat pump in Penzance?
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 Penzance home gives a room-by-room list.
Can you service a heat pump in Penzance that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Penzance, whoever fitted them. Tell us the make and model when you book.
