Before you book: replacing an oil or LPG boiler with a heat pump in Holyhead
Every property in Holyhead is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
If your home near Holyhead is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Rural properties near Holyhead 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.
- Rural and village homes off the mains gas grid
- Owners tired of fuel deliveries and tank maintenance
- Detached houses and bungalows with garden space for the unit
What's included
- MCS certificate and grant application in England and Wales where eligible
- Help arranging LPG tank collection with your supplier
- Free survey with a detailed heat loss calculation for older construction
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Oil tank draining and removal or making safe, as set out in your quote
Bungalows and detached houses near Holyhead running on LPG can move to a heat pump, with the tank collected by the supplier.
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 Holyhead 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 Holyhead: questions
How long does installation take in Holyhead?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Holyhead home states the expected time.
How long does a heat pump survey take in Holyhead?
A home survey in Holyhead 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 Holyhead?
Survey dates depend on how busy installers are in Gwynedd. 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.
