Oil and LPG boiler replacement in Nairn: what to expect
Most homes can run on a heat pump if the system is designed properly, and Nairn is no different. The key is matching the heat pump and radiators to the home's heat loss.
Owners across the Highlands and Islands can have oil tank removal arranged alongside a heat pump installation in Nairn. Rural properties near Nairn 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.
- 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
- Oil tank draining and removal or making safe, as set out in your quote
- Network operator notification and electrical connection
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Free survey with a detailed heat loss calculation for older construction
- Help arranging LPG tank collection with your supplier
Bungalows and detached houses near Nairn running on LPG can move to a heat pump, with the tank collected by the supplier.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Nairn 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 Nairn property at survey.

Short winter days in Nairn and what they mean
On the shortest day Nairn gets only about 6 hours 34 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.

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