We cover Marlborough and nearby Swindon, Calne and the rest of Wiltshire. A heat pump is a whole-system change, so the survey looks at radiators, pipework, the hot water cylinder and the best spot for the outdoor unit.

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 Marlborough 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 Marlborough and what they mean
Marlborough sees roughly 7 hours 50 minutes of daylight in late December against 16 hours 37 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 Marlborough: questions
Can you service a heat pump in Marlborough that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Marlborough, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on a Marlborough 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 Marlborough home.
How long does a heat pump survey take in Marlborough?
A home survey in Marlborough 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 you cover Swindon as well as Marlborough?
Yes. We arrange surveys and installation in Swindon, which is about 10 miles north of Marlborough, and across Wiltshire.
