What to know about replacing an oil or LPG boiler with a heat pump in Port Talbot
Every property in Port Talbot 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.
Rural properties near Port Talbot usually have garden space for the outdoor unit, sited away from windows and sheltered where possible. Cottages and farmhouses in and around Port Talbot often have solid walls, so the survey looks closely at construction and draughts.
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.
- Rural and village homes off the mains gas grid
- Owners tired of fuel deliveries and tank maintenance
- Eligible homes in England and Wales within the higher grant window
What's included
- Free survey with a detailed heat loss calculation for older construction
- Network operator notification and electrical connection
- Removal of the oil or LPG boiler and flue
- MCS certificate and grant application in England and Wales where eligible
- Outdoor unit, heat pump cylinder, controls and radiator changes
For homes outside Port Talbot reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance.
Grants and rules for heat pumps in Wales
Homes in Port Talbot 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.

How long is the heating season in Port Talbot?
On the shortest day Port Talbot gets about 7 hours 49 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 Port Talbot: questions
How long does installation take in Port Talbot?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Port Talbot home states the expected time.
Where would the outdoor unit go on a Port Talbot 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 Port Talbot home.
Do you cover Briton Ferry as well as Port Talbot?
Yes. We arrange surveys and installation in Briton Ferry, which is about 3 miles north-west of Port Talbot, and across West Glamorgan.
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.
What happens with a leased LPG tank?
Leased LPG tanks belong to the supplier, so the supplier arranges collection. Check your contract for notice periods and any charges before you fix a date. We time the switchover so you are not left without heating, and once the heat pump is commissioned the supplier can empty and remove the tank. Bottled LPG cylinders are simply returned.
