What to know about replacing an oil or LPG boiler with a heat pump in Porthcawl
In Porthcawl, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
For homes outside Porthcawl reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance. Rural properties near Porthcawl usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.
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
- Older oil boilers nearing the end of their life
- Rural and village homes off the mains gas grid
What's included
- Oil tank draining and removal or making safe, as set out in your quote
- Network operator notification and electrical connection
- Free survey with a detailed heat loss calculation for older construction
- MCS certificate and grant application in England and Wales where eligible
- Outdoor unit, heat pump cylinder, controls and radiator changes
Bungalows and detached houses near Porthcawl 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 Porthcawl 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 Porthcawl: questions
What size heat pump does a Porthcawl 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 Porthcawl home.
How long does a heat pump survey take in Porthcawl?
A home survey in Porthcawl 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.
How soon can you survey a home in Porthcawl?
Survey dates depend on how busy installers are in Mid Glamorgan. We offer the next available dates when you enquire and confirm them in writing.
Will I need bigger radiators in an older cottage or farmhouse?
Often in some rooms, because thick solid walls and older windows lose more heat, and heat pumps work at lower water temperatures than oil boilers. The survey checks each room. Rooms with high ceilings or large windows are common candidates for a larger radiator. Where swapping radiators is impractical, a high-temperature unit can be considered, with lower efficiency as the trade-off.
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.
