Before you book: heat pump radiator upgrades in Keynsham
A heat pump suits most Keynsham homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Extensions and kitchen-diners around Keynsham with large glazed areas get their own radiator calculation. Radiator fitting in Keynsham is scheduled with your heat pump installation so the system is drained only once.
We size each radiator to your room-by-room heat loss so a heat pump can heat your home at a low, efficient flow temperature.
- Rooms with little wall space, where a fan-assisted radiator fits better
- Extensions and loft conversions with large areas of glazing
- Homes switching from a gas, oil or LPG boiler to a heat pump
What's included
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Supply and fitting of new radiators, valves and brackets
- Pipework checks and any agreed pipe upgrades
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Room-by-room heat loss figures for every heated room
We plan radiator upgrades in Keynsham so floorboards are lifted only where pipework genuinely needs changing.
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 Keynsham quote.
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 radiators prices in Keynsham
Guide prices for Keynsham and the rest of Somerset are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.

Installed, inc VAT. The survey lists which radiators need changing.
Winter daylight and heating in Keynsham
Keynsham sees roughly 7 hours 50 minutes of daylight in late December against 16 hours 37 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.
What happens after you enquire in Keynsham?
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Keynsham 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.
Heat pump radiator upgrades in Keynsham: questions
Can you service a heat pump in Keynsham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Keynsham, whoever fitted them. Tell us the make and model when you book.
Do you cover Kingswood as well as Keynsham?
Yes. We arrange surveys and installation in Kingswood, which is about 3 miles north of Keynsham, and across Somerset.
What size heat pump does a Keynsham 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 Keynsham home.
Are fan-assisted radiators noisy?
Fan-assisted radiators make a low, steady fan sound when running at higher output, and many have quieter settings for bedrooms at night. They are useful where wall space is short, such as a kitchen with few clear walls. They need a small electrical supply, which we plan into the installation if you choose them.
How much does a heat pump radiator cost?
A replacement radiator sized for a heat pump has a guide price of £250–£450 each, installed and including VAT. Upgrading about ten radiators in a typical home has a guide price of £2,000–£5,000. The final price is fixed in your written quote after the survey, once the radiator schedule shows exactly which radiators change.
