Before you book: replacing an oil or LPG boiler with a heat pump in Carrickfergus
Homes around Carrickfergus range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
For homes outside Carrickfergus reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance. If your home near Carrickfergus is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries.
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.
- Owners tired of fuel deliveries and tank maintenance
- Detached houses and bungalows with garden space for the unit
- Older oil boilers nearing the end of their life
What's included
- Network operator notification and electrical connection
- Free survey with a detailed heat loss calculation for older construction
- Help arranging LPG tank collection with your supplier
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Oil tank draining and removal or making safe, as set out in your quote
Owners across County Antrim can have oil tank removal arranged alongside a heat pump installation in Carrickfergus.
Grants and rules for heat pumps in Northern Ireland
The Boiler Upgrade Scheme covers England and Wales only, and there is currently no dedicated heat pump grant for homeowners in Northern Ireland. Our quote for a Carrickfergus home is therefore shown without a grant deduction; if support becomes available we will tell you how it applies.
Installing heat pumps has been zero-rated for VAT in Northern Ireland since 1 May 2023, in line with the rest of the UK, until 31 March 2027. Northern Ireland has its own permitted development rules and building regulations, and we confirm what applies to your Carrickfergus property at survey.

Replacing an oil or LPG boiler with a heat pump in Carrickfergus: questions
Do I need new radiators for a heat pump in Carrickfergus?
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 Carrickfergus home gives a room-by-room list.
Can you service a heat pump in Carrickfergus that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Carrickfergus, whoever fitted them. Tell us the make and model when you book.
How long does a heat pump survey take in Carrickfergus?
A home survey in Carrickfergus 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 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.
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.
