Oil and LPG boiler replacement in Pontardawe: what to expect
Homes around Pontardawe range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Rural properties near Pontardawe usually have garden space for the outdoor unit, sited away from windows and sheltered where possible. Owners across West Glamorgan can have oil tank removal arranged alongside a heat pump installation in Pontardawe.
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
- Detached houses and bungalows with garden space for the unit
- Rural and village homes off the mains gas grid
What's included
- Free survey with a detailed heat loss calculation for older construction
- Help arranging LPG tank collection with your supplier
- Oil tank draining and removal or making safe, as set out in your quote
- MCS certificate and grant application in England and Wales where eligible
- Removal of the oil or LPG boiler and flue
Bungalows and detached houses near Pontardawe 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 Pontardawe 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.

Short winter days in Pontardawe and what they mean

Replacing an oil or LPG boiler with a heat pump in Pontardawe: questions
What size heat pump does a Pontardawe 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 Pontardawe home.
How long does installation take in Pontardawe?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Pontardawe home states the expected time.
Do you cover Clydach as well as Pontardawe?
Yes. We arrange surveys and installation in Clydach, which is about 3 miles south-west of Pontardawe, and across West Glamorgan.
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.
