What to know about air-to-air heat pumps in Portishead
In Portishead, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Top-floor rooms in Portishead that overheat in summer gain from the cooling an air-to-air system provides. Flats in Portishead on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework.
An air-to-air heat pump warms rooms directly with air, and can cool them in summer, but it does not heat your hot water.
- Homes where fitting radiators and pipework would be very disruptive
- Extensions, conservatories and garden rooms
- Flats and apartments with storage or panel heaters
What's included
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Condensate drains and neat external pipe covers
- Electrical supply and controls set up for each room
- Free survey covering rooms to heat, unit positions and hot water options
- Outdoor unit and indoor units for each room
A survey in Portishead covers indoor unit positions, pipe routes and hot water for homes across Somerset.
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 Portishead 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.
What to budget for air-to-air heat pumps in Portishead
The ranges below are typical installed prices for homes in Somerset, including VAT. A survey sets the exact figure, because two similar-looking houses in Portishead can need quite different radiators and pipework.
| System | Installed guide price |
|---|---|
| Air-to-air heat pump, 1–2 rooms | £2,400–£5,000 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,000–£8,000 |
Installed, inc VAT. Air-to-air systems heat (and can cool) rooms but do not provide hot water. In England and Wales the Boiler Upgrade Scheme gives £2,500 towards an air-to-air system in a home, deducted from your quote where eligible.
Designing for Portishead's winters
On the shortest day Portishead gets about 7 hours 50 minutes of daylight, and the winter sun reaches only around 15° 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.

Air-to-air heat pumps in Portishead: questions
Do I need new radiators for a heat pump in Portishead?
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 Portishead home gives a room-by-room list.
What size heat pump does a Portishead 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 Portishead home.
How long does installation take in Portishead?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Portishead home states the expected time.
Are air-to-air heat pumps suitable for flats?
Often, yes. They need no radiators, pipework or cylinder, so they suit flats heated by storage or panel heaters. You need a position for the outdoor unit, such as a balcony, wall bracket or ground-floor yard, and leaseholders normally need the freeholder's or management company's consent. Planning rules for flats differ by nation, so we check what applies at survey.
Can air-to-air heat pumps cool as well as heat?
Yes. Most air-to-air systems can reverse their cycle to cool and dehumidify rooms in summer, which makes them useful for loft rooms, south-facing extensions and home offices that overheat. Cooling uses electricity, so running costs rise if it is used heavily. You control heating and cooling for each room separately.
