Heat pump radiators in Cwmbran: what to expect
Homes around Cwmbran range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Radiator fitting in Cwmbran is scheduled with your heat pump installation so the system is drained only once. We plan radiator upgrades in Cwmbran so floorboards are lifted only where pipework genuinely needs changing.
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.
- Extensions and loft conversions with large areas of glazing
- 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
- Supply and fitting of new radiators, valves and brackets
- Balancing every radiator so each room heats evenly
- A radiator schedule showing which radiators stay, which change and their outputs
- Pipework checks and any agreed pipe upgrades
- Room-by-room heat loss figures for every heated room
For period homes in Cwmbran and across Gwent, column radiators can keep the character of a room while giving enough heat at low temperatures.
Grants and rules for heat pumps in Wales
Homes in Cwmbran can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Wales has its own permitted development rules for air source heat pumps, so we check what applies to your property, including listed building and conservation-area constraints, at the survey.

Heat pump radiator upgrades in Cwmbran: questions
How long does a heat pump survey take in Cwmbran?
A home survey in Cwmbran usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Do you cover Pontypool as well as Cwmbran?
Yes. We arrange surveys and installation in Pontypool, which is about 3 miles north of Cwmbran, and across Gwent.
Do I need new radiators for a heat pump in Cwmbran?
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 Cwmbran home gives a room-by-room list.
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.
Will new radiators be much bigger than my old ones?
Sometimes, but not always. Swapping a single-panel radiator for a double or triple-panel model of the same height and width can raise output substantially, adding only depth from the wall. Where that is not enough, a longer or taller radiator, or a second radiator in the room, may be needed. We agree sizes and positions with you before anything is ordered.
