Gas boiler to heat pump for Lanark homes
Homes around Lanark range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Installers in Lanark take out the old boiler and flue and seal the wall opening as part of the job. Semi-detached and terraced houses in Lanark 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.
- System or regular boiler homes with an existing airing cupboard
- Households ready to give up gas entirely and drop the standing charge
- Combi owners who can find space for a hot water cylinder
What's included
- Removal of the gas boiler, flue and any loft tanks
- Heat pump cylinder, outdoor unit and weather compensation controls
- 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
If your Lanark home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Lanark 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 Lanark property at survey.

Short winter days in Lanark and what they mean
On the shortest day Lanark gets only about 7 hours 01 minutes of daylight, with the sun around 11° 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 a gas boiler with a heat pump in Lanark: questions
Do I need new radiators for a heat pump in Lanark?
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 Lanark home gives a room-by-room list.
Do you cover Carluke as well as Lanark?
Yes. We arrange surveys and installation in Carluke, which is about 5 miles north-west of Lanark, and across Lanarkshire.
Can you service a heat pump in Lanark that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Lanark, whoever fitted them. Tell us the make and model when you book.
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.
Will my hot water run out with a heat pump?
Not if the cylinder is sized properly for your household. The survey asks how many people live in the home, how many bathrooms you have and whether you prefer baths or showers, then sizes the cylinder to suit. The heat pump reheats the cylinder on a schedule, often overnight and again during the day, and an immersion heater acts as a backup.
