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 Nailsea 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 Nailsea and what they mean
Nailsea sees roughly 7 hours 50 minutes of daylight in late December against 16 hours 38 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.
Heat pumps in Nailsea: questions
Can you service a heat pump in Nailsea that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Nailsea, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Nailsea?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Nailsea home states the expected time.
How soon can you survey a home in Nailsea?
Survey dates depend on how busy installers are in Somerset. We offer the next available dates when you enquire and confirm them in writing.
Where would the outdoor unit go on a Nailsea 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 Nailsea home.
