Before you book: replacing an oil or LPG boiler with a heat pump in Hay-on-Wye
In Hay-on-Wye, 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 Hay-on-Wye reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance. Bungalows and detached houses near Hay-on-Wye running on LPG can move to a heat pump, with the tank collected by the supplier.
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
- Detached houses and bungalows with garden space for the unit
- Owners tired of fuel deliveries and tank maintenance
What's included
- Help arranging LPG tank collection with your supplier
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Free survey with a detailed heat loss calculation for older construction
- Oil tank draining and removal or making safe, as set out in your quote
- Removal of the oil or LPG boiler and flue
Rural properties near Hay-on-Wye usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.
Grants and rules for heat pumps in Wales
Homes in Hay-on-Wye 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 Hay-on-Wye: questions
How long does a heat pump survey take in Hay-on-Wye?
A home survey in Hay-on-Wye 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.
Can you service a heat pump in Hay-on-Wye that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Hay-on-Wye, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Hay-on-Wye 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 Hay-on-Wye 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.
Can a heat pump cope with an exposed rural spot?
Yes. Air source heat pumps are designed to keep working well below freezing, and they periodically defrost, giving off a little vapour, which is normal. In exposed locations the installer chooses a sheltered position where possible, raises the unit to clear snow and let defrost water drain, and sizes the system for the local winter design temperature used in the heat loss calculation.
