What to know about replacing an oil or LPG boiler with a heat pump in Barry
Homes around Barry range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
If your home near Barry is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Owners across South Glamorgan can have oil tank removal arranged alongside a heat pump installation in Barry.
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.
- Owners tired of fuel deliveries and tank maintenance
- Detached houses and bungalows with garden space for the unit
- Older oil boilers nearing the end of their life
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
- Network operator notification and electrical connection
- Outdoor unit, heat pump cylinder, controls and radiator changes
Bungalows and detached houses near Barry 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 Barry 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.

How long is the heating season in Barry?
On the shortest day Barry gets about 7 hours 51 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.

Replacing an oil or LPG boiler with a heat pump in Barry: questions
Can you service a heat pump in Barry that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Barry, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on a Barry 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 Barry home.
How long does a heat pump survey take in Barry?
A home survey in Barry 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 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.
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.
