What to know about replacing an oil or LPG boiler with a heat pump in Cwmbran
Most homes can run on a heat pump if the system is designed properly, and Cwmbran is no different. The key is matching the heat pump and radiators to the home's heat loss.
If your home near Cwmbran is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Owners across Gwent can have oil tank removal arranged alongside a heat pump installation in Cwmbran.
Off-gas homes have a lot to plan when switching to a heat pump: the fuel tank, older walls, rural power supplies and higher heat loss.
- Eligible homes in England and Wales within the higher grant window
- Older oil boilers nearing the end of their life
- Owners tired of fuel deliveries and tank maintenance
What's included
- Oil tank draining and removal or making safe, as set out in your quote
- Free survey with a detailed heat loss calculation for older construction
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Removal of the oil or LPG boiler and flue
- MCS certificate and grant application in England and Wales where eligible
Bungalows and detached houses near Cwmbran running on LPG can move to a heat pump, with the tank collected by the supplier.
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.
There is no VAT on installing a heat pump anywhere in the UK, Wales included, until 31 March 2027. Planning rules for heat pumps in Wales are set by the Welsh Government and differ from England's, so the surveyor checks the unit position against them.

Replacing an oil or LPG boiler with a heat pump in Cwmbran: questions
How long does installation take in Cwmbran?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Cwmbran home states the expected time.
Can you service a heat pump in Cwmbran that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Cwmbran, whoever fitted them. Tell us the make and model when you book.
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.
Is a heat pump cheaper to run than oil?
It depends on oil prices, your home's insulation, the flow temperature and your electricity tariff, so there is no single answer. At the October to December 2026 price cap, a heat pump with a seasonal efficiency of 3.0 delivers heat for about 8.8p per kWh, and at 3.5 about 7.5p. Compare that with your oil cost per kWh of heat, allowing for your boiler's efficiency; the survey estimate gives a figure for your home.
Do I have to remove my oil tank?
Not always, but it should be emptied and made safe. A tank in good condition can be drained, cleaned and left in place, though most owners prefer to have it taken away to free up space. Old or damaged tanks are usually removed. Your quote says which option is included, and any remaining oil and sludge is disposed of properly.
