Before you book: heat pump radiator upgrades in Didcot
The question for a Didcot 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.
Many older houses in Didcot still have their original single-panel radiators, so the survey checks each one against the room it heats. In Didcot, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump.
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.
- Homeowners who want the lowest practical flow temperature for efficiency
- Rooms that already feel slow to heat, such as bay-windowed living rooms
- Extensions and loft conversions with large areas of glazing
What's included
- Supply and fitting of new radiators, valves and brackets
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Pipework checks and any agreed pipe upgrades
- A radiator schedule showing which radiators stay, which change and their outputs
- Balancing every radiator so each room heats evenly
For period homes in Didcot and across Oxfordshire, column radiators can keep the character of a room while giving enough heat at low temperatures.
Grants and rules for heat pumps in England
Homes in Didcot 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.

How long is the heating season in Didcot?
On the shortest day Didcot gets about 7 hours 48 minutes of daylight, with the noon sun around 15° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Heat pump radiator upgrades in Didcot: questions
How soon can you survey a home in Didcot?
Survey dates depend on how busy installers are in Oxfordshire. We offer the next available dates when you enquire and confirm them in writing.
Where would the outdoor unit go on a Didcot 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 Didcot home.
How long does installation take in Didcot?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Didcot home states the expected time.
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.
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.
