Oil and LPG boiler replacement for Abergavenny homes

Most homes can run on a heat pump if the system is designed properly, and Abergavenny is no different. The key is matching the heat pump and radiators to the home's heat loss.

Rural properties near Abergavenny usually have garden space for the outdoor unit, sited away from windows and sheltered where possible. Cottages and farmhouses in and around Abergavenny 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.

  • Detached houses and bungalows with garden space for the unit
  • Owners tired of fuel deliveries and tank maintenance
  • Older oil boilers nearing the end of their life

What's included

  • Help arranging LPG tank collection with your supplier
  • MCS certificate and grant application in England and Wales where eligible
  • Network operator notification and electrical connection
  • Outdoor unit, heat pump cylinder, controls and radiator changes
  • Oil tank draining and removal or making safe, as set out in your quote

For homes outside Abergavenny 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

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 Abergavenny quote.

Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Wales has its own permitted development rules for air source heat pumps, so we check what applies to your property, including listed building and conservation-area constraints, at the survey.

Replacing an oil or LPG boiler with a heat pump in Abergavenny: questions

How long does installation take in Abergavenny?

Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for an Abergavenny home states the expected time.

Do you cover Crickhowell as well as Abergavenny?

Yes. We arrange surveys and installation in Crickhowell, which is about 6 miles north-west of Abergavenny, and across Gwent.

Do I need new radiators for a heat pump in Abergavenny?

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 Abergavenny home gives a room-by-room list.

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.

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.
