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 Diss quote.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

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