Air-to-air heat pumps for Trowbridge homes
The question for a Trowbridge home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
For terraced homes in Trowbridge, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room. Installers in Trowbridge plan condensate drains and pipe covers so indoor and outdoor runs stay neat.
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.
- Rooms that get too hot in summer as well as cold in winter
- Flats and apartments with storage or panel heaters
- Extensions, conservatories and garden rooms
What's included
- Free survey covering rooms to heat, unit positions and hot water options
- Outdoor unit and indoor units for each room
- Electrical supply and controls set up for each room
- Condensate drains and neat external pipe covers
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
Flats in Trowbridge on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework.
Grants and rules for heat pumps in England
Homes in Trowbridge 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.
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 Trowbridge
Here are typical prices for air-to-air heat pumps in Wiltshire, installed and including VAT. Use the guide price tool for a figure based on your home, then a survey confirms it in writing.
| System | Installed guide price |

| Air-to-air heat pump, 1–2 rooms | £2,400–£5,050 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,050–£8,100 |
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 Trowbridge's winters
Trowbridge sees roughly 7 hours 51 minutes of daylight in late December against 16 hours 36 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.

Air-to-air heat pumps in Trowbridge: questions
What size heat pump does a Trowbridge 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 Trowbridge home.
Do you cover Bradford-on-Avon as well as Trowbridge?
Yes. We arrange surveys and installation in Bradford-on-Avon, which is about 3 miles north-west of Trowbridge, and across Wiltshire.
Can you service a heat pump in Trowbridge that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Trowbridge, whoever fitted them. Tell us the make and model when you book.
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.
Is there a grant for air-to-air heat pumps?
In England and Wales, yes: the Boiler Upgrade Scheme includes a grant of £2,500 for air-to-air heat pumps in homes, from 28 April 2026. The MCS-certified installer applies to Ofgem and deducts it from your quote, subject to the scheme's conditions. The scheme does not cover Scotland or Northern Ireland; in Scotland, Home Energy Scotland has its own rules.
