What to know about replacing a gas boiler with a heat pump in Nairn
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.
Rear gardens and side returns in Nairn usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours. Semi-detached and terraced houses in Nairn often have an airing cupboard that can be reused for a heat pump cylinder.
Moving from mains gas to a heat pump means finding cylinder space, deciding what happens to the gas supply and comparing running costs on realistic assumptions.
- Households ready to give up gas entirely and drop the standing charge
- Combi owners who can find space for a hot water cylinder
- System or regular boiler homes with an existing airing cupboard
What's included
- Capping of the gas pipe at the boiler position where you are giving up gas
- System flush and radiator upgrades where the design calls for them
- Free survey with heat loss calculation and cylinder siting
- Removal of the gas boiler, flue and any loft tanks
- Heat pump cylinder, outdoor unit and weather compensation controls
Households across the Highlands and Islands moving off gas can have a survey in Nairn that compares running costs on realistic assumptions.
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.

Replacing a gas boiler with a heat pump in Nairn: questions
How soon can you survey a home in Nairn?
Survey dates depend on how busy installers are in the Highlands and Islands. We offer the next available dates when you enquire and confirm them in writing.
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.
How long does installation take in Nairn?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Nairn home states the expected time.
Can a heat pump replace a combi boiler?
Yes, but you need room for a hot water cylinder, because heat pumps store hot water rather than heating it on demand. Most homes find a space in a cupboard, utility room, garage or under the stairs, and compact or combined indoor units help where space is tight. The survey measures the options first, so you know where everything will go before you accept the quote.
Do I need to replace the cylinder I already have?
Usually, yes. Older cylinders have a small internal coil designed for water from a boiler at around 60–70°C, and they cannot take in heat quickly enough at the lower temperatures a heat pump runs at. A heat pump cylinder has a larger coil. On its own, a cylinder supplied and fitted has a guide price of £1,200–£2,200, installed and including VAT, though it is normally part of the full system price.
