Air source heat pump installation in Amesbury: what to expect
Most homes can run on a heat pump if the system is designed properly, and Amesbury is no different. The key is matching the heat pump and radiators to the home's heat loss.
Terraced streets in Amesbury often mean a compact unit position at the rear, so siting and sound levels are checked carefully. Homeowners across Wiltshire can arrange a survey in Amesbury for a room-by-room design and a written quote before committing to anything.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Owners who want one contract covering design, fitting and paperwork
- Homes replacing a gas, oil, LPG or electric heating system
- Houses with reasonable insulation, or a plan to improve it
What's included
- MCS registration and certificate, plus network operator notification
- Removal of the old boiler or heaters
- Outdoor unit, hot water cylinder and weather compensation controls
- Radiator and pipework changes where the design needs them
- Boiler Upgrade Scheme application in England and Wales where eligible
Installers working in Amesbury plan the order of work so heating and hot water are off for as short a time as practical.
Grants and rules for heat pumps in England
Homes in Amesbury 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.
What to budget for air source heat pump installation in Amesbury
The ranges below are typical installed prices for homes in Wiltshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Amesbury can need quite different radiators and pipework.
| Home | Typical size | Installed guide price | After £7,500 grant |
|---|---|---|---|
| 1–2 bedroom flat or small terrace | 4–5 kW | £9,600–£12,650 | £2,100–£5,150 |
| 2–3 bedroom terrace or semi | 5–7 kW | £10,600–£13,650 | £3,100–£6,150 |
| 3 bedroom semi or small detached | 6–9 kW | £12,100–£15,650 | £4,600–£8,150 |
| 4 bedroom detached | 8–12 kW | £14,150–£18,200 | £6,650–£10,700 |
| 5+ bedroom or larger older house | 11–16 kW | £16,650–£22,750 | £9,150–£15,250 |
Installed, inc VAT: unit, cylinder, controls, minor pipework and commissioning.
Designing for Amesbury's winters
Amesbury sees roughly 7 hours 53 minutes of daylight in late December against 16 hours 35 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.

- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Air source heat pump installation in Amesbury: questions
Do I need new radiators for a heat pump in Amesbury?
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 Amesbury home gives a room-by-room list.
What size heat pump does an Amesbury 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 Amesbury home.
Do you cover Salisbury as well as Amesbury?
Yes. We arrange surveys and installation in Salisbury, which is about 7 miles south of Amesbury, and across Wiltshire.
How long does an air source heat pump installation take?
A typical home installation takes 2–4 days on site. It takes longer if several radiators are being replaced, pipework is being upgraded or the cylinder is going in a new location. Your quote sets out the expected programme, including when you will be without heating and hot water. Timings are typical rather than fixed, because older homes sometimes reveal surprises once floorboards are lifted.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
