Before you book: air source heat pump installation in Bristol
Every property in Bristol is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Homeowners across Bristol can arrange a survey in Bristol for a room-by-room design and a written quote before committing to anything. Installers working in Bristol plan the order of work so heating and hot water are off for as short a time as practical.
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.
- Homes replacing a gas, oil, LPG or electric heating system
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Owners who want one contract covering design, fitting and paperwork
What's included
- MCS registration and certificate, plus network operator notification
- Free home survey and room-by-room heat loss calculation
- Boiler Upgrade Scheme application in England and Wales where eligible
- Radiator and pipework changes where the design needs them
- System design, unit sizing and a written quote
In Bristol, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
Grants and rules for heat pumps in England
Homes in Bristol 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 Bristol
The ranges below are typical installed prices for homes in Bristol, including VAT. A survey sets the exact figure, because two similar-looking houses in Bristol 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 | £9,700–£12,750 | £2,200–£5,250 |
| 2–3 bedroom terrace or semi | 5–7 kW | £10,700–£13,750 | £3,200–£6,250 |

| 4 bedroom detached | 8–12 kW | £14,300–£18,350 | £6,800–£10,850 |

Installed, inc VAT: unit, cylinder, controls, minor pipework and commissioning.
How long is the heating season in Bristol?
Bristol sees roughly 7 hours 50 minutes of daylight in late December against 16 hours 38 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.
The steps for air source heat pump installation in Bristol
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Bristol home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Air source heat pump installation in Bristol: questions
Where would the outdoor unit go on a Bristol 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 Bristol home.
Do I need new radiators for a heat pump in Bristol?
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 Bristol home gives a room-by-room list.
What size heat pump does a Bristol 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 Bristol home.
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.
Can I cancel after accepting the quote?
Nothing is ordered until you accept the written quote. Where the contract is agreed away from our premises, for example at your kitchen table, you can cancel within 14 days under the Consumer Contracts Regulations 2013. If you ask us to start sooner and then cancel, you pay only for work done up to that point.
