We cover Portsmouth and nearby Gosport, Fareham and the rest of Hampshire. 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
Homes in Portsmouth can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
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 pump guide prices in Portsmouth
The ranges below are typical installed prices for homes in Hampshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Portsmouth can need quite different radiators and pipework.

Winter daylight and heating in Portsmouth
On the shortest day Portsmouth gets about 7 hours 57 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 Portsmouth: questions
Do you cover Gosport as well as Portsmouth?
Yes. We arrange surveys and installation in Gosport, which is about 2 miles west of Portsmouth, and across Hampshire.
Where would the outdoor unit go on a Portsmouth 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 Portsmouth home.
Do I need new radiators for a heat pump in Portsmouth?
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 Portsmouth home gives a room-by-room list.
How long does installation take in Portsmouth?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Portsmouth home states the expected time.
