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 Seaham 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.

Heat pumps in Seaham: questions
How long does a heat pump survey take in Seaham?
A home survey in Seaham 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.
What size heat pump does a Seaham 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 Seaham home.
How long does installation take in Seaham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Seaham home states the expected time.
Can you service a heat pump in Seaham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Seaham, whoever fitted them. Tell us the make and model when you book.
