What to know about replacing an oil or LPG boiler with a heat pump in Tenby
A heat pump suits most Tenby homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
For homes outside Tenby reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance. Rural properties near Tenby 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.
- Eligible homes in England and Wales within the higher grant window
- Older oil boilers nearing the end of their life
- Rural and village homes off the mains gas grid
What's included
- Network operator notification and electrical connection
- Oil tank draining and removal or making safe, as set out in your quote
- Free survey with a detailed heat loss calculation for older construction
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Removal of the oil or LPG boiler and flue
If your home near Tenby is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries.
Grants and rules for heat pumps in Wales
In Wales the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027; £2,500 for air-to-air). The MCS-certified installer named in your quote applies to Ofgem for you, and the grant comes off your Tenby quote.
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 Tenby: questions
How long does a heat pump survey take in Tenby?
A home survey in Tenby 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 need new radiators for a heat pump in Tenby?
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 Tenby home gives a room-by-room list.
Where would the outdoor unit go on a Tenby 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 Tenby home.
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.
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.
