Before you book: heat pump radiator upgrades in Feltham
Every property in Feltham 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.
In Feltham, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump. Radiator fitting in Feltham 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
- Homeowners who want the lowest practical flow temperature for efficiency
- Homes switching from a gas, oil or LPG boiler to a heat pump
What's included
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- A radiator schedule showing which radiators stay, which change and their outputs
- Supply and fitting of new radiators, valves and brackets
- Balancing every radiator so each room heats evenly
Extensions and kitchen-diners around Feltham with large glazed areas get their own radiator calculation.
Grants and rules for heat pumps in England
Homes in Feltham 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 Feltham?
On the shortest day Feltham gets about 7 hours 50 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Heat pump radiator upgrades in Feltham: questions
Do I need new radiators for a heat pump in Feltham?
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 Feltham home gives a room-by-room list.
Do you cover Hounslow as well as Feltham?
Yes. We arrange surveys and installation in Hounslow, which is about 3 miles north-east of Feltham, and across Greater London.
Can you service a heat pump in Feltham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Feltham, whoever fitted them. Tell us the make and model when you book.
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.
Can radiators be changed without draining the whole system?
Radiator changes normally mean draining the heating system, which is why they are usually done as part of the heat pump installation. The system is then refilled, flushed, treated with inhibitor and balanced. Doing the radiators at the same time avoids draining twice and means the new radiators are commissioned with the heat pump.
