What to know about replacing an oil or LPG boiler with a heat pump in Lisburn
Homes around Lisburn range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
If your home near Lisburn is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Bungalows and detached houses near Lisburn 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.
- Older oil boilers nearing the end of their life
- Detached houses and bungalows with garden space for the unit
- Owners tired of fuel deliveries and tank maintenance
What's included
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Help arranging LPG tank collection with your supplier
- Network operator notification and electrical connection
- 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
Owners across County Antrim can have oil tank removal arranged alongside a heat pump installation in Lisburn.
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 Lisburn 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 Lisburn property at survey.

Winter daylight and heating in Lisburn

Replacing an oil or LPG boiler with a heat pump in Lisburn: questions
What size heat pump does a Lisburn 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 Lisburn home.
Do you cover Belfast as well as Lisburn?
Yes. We arrange surveys and installation in Belfast, which is about 7 miles north-east of Lisburn, and across County Antrim.
Do I need new radiators for a heat pump in Lisburn?
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 Lisburn home gives a room-by-room list.
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.
What happens with a leased LPG tank?
Leased LPG tanks belong to the supplier, so the supplier arranges collection. Check your contract for notice periods and any charges before you fix a date. We time the switchover so you are not left without heating, and once the heat pump is commissioned the supplier can empty and remove the tank. Bottled LPG cylinders are simply returned.
