What to know about replacing an oil or LPG boiler with a heat pump in Inverness
Every property in Inverness 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.
Bungalows and detached houses near Inverness running on LPG can move to a heat pump, with the tank collected by the supplier. Owners across the Highlands and Islands can have oil tank removal arranged alongside a heat pump installation in Inverness.
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
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Removal of the oil or LPG boiler and flue
- Oil tank draining and removal or making safe, as set out in your quote
- Free survey with a detailed heat loss calculation for older construction
If your home near Inverness is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Inverness can apply to Home Energy Scotland for a grant of up to £7,500 towards a heat pump, with up to £1,500 more for eligible rural and island homes, plus an optional interest-free loan of up to £7,500. You need a written funding offer before any work starts.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Scotland has its own permitted development rules for air source heat pumps and its own building standards, so we confirm what applies to your Inverness property at survey.

Winter daylight and heating in Inverness
On the shortest day Inverness gets only about 6 hours 35 minutes of daylight, with the sun around 9° up at noon. Long Scottish winters mean the heat pump runs for much of the year, so careful sizing, good controls and correctly sized radiators make a real difference.
What happens after you enquire in Inverness?
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Inverness; the surveyor measures rooms, windows and radiators and looks at cylinder space.
- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Replacing an oil or LPG boiler with a heat pump in Inverness: questions
Do you cover Dingwall as well as Inverness?
Yes. We arrange surveys and installation in Dingwall, which is about 11 miles north-west of Inverness, and across the Highlands and Islands.
How long does installation take in Inverness?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for an Inverness home states the expected time.
What size heat pump does an Inverness 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 Inverness home.
Is a heat pump cheaper to run than oil?
It depends on oil prices, your home's insulation, the flow temperature and your electricity tariff, so there is no single answer. At the October to December 2026 price cap, a heat pump with a seasonal efficiency of 3.0 delivers heat for about 8.8p per kWh, and at 3.5 about 7.5p. Compare that with your oil cost per kWh of heat, allowing for your boiler's efficiency; the survey estimate gives a figure for your home.
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.
