What to know about replacing an oil or LPG boiler with a heat pump in Llangollen
A heat pump suits most Llangollen homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Cottages and farmhouses in and around Llangollen often have solid walls, so the survey looks closely at construction and draughts. Owners across Clwyd can have oil tank removal arranged alongside a heat pump installation in Llangollen.
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.
- Older oil boilers nearing the end of their life
- Detached houses and bungalows with garden space for the unit
- Eligible homes in England and Wales within the higher grant window
What's included
- Network operator notification and electrical connection
- MCS certificate and grant application in England and Wales where eligible
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Removal of the oil or LPG boiler and flue
- Oil tank draining and removal or making safe, as set out in your quote
Bungalows and detached houses near Llangollen 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 Llangollen 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 Llangollen: questions
Can you service a heat pump in Llangollen that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Llangollen, whoever fitted them. Tell us the make and model when you book.
Do I need new radiators for a heat pump in Llangollen?
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 Llangollen home gives a room-by-room list.
Do you cover Rhosllannerchrugog as well as Llangollen?
Yes. We arrange surveys and installation in Rhosllannerchrugog, which is about 6 miles north-east of Llangollen, and across Clwyd.
How much is the grant for replacing an oil boiler with a heat pump?
In England and Wales, the Boiler Upgrade Scheme grant is £9,000 when an air-to-water heat pump replaces oil or LPG heating, for installations from 21 July 2026 to 31 March 2027. Otherwise the standard £7,500 applies. The installer claims it and deducts it from your quote. Scotland's Home Energy Scotland funding works differently and includes extra for eligible rural homes; Northern Ireland has no dedicated homeowner scheme at present.
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.
