Before you book: replacing a gas boiler with a heat pump in Cumbernauld
The question for a Cumbernauld home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Many gas-heated homes in Cumbernauld have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder. Semi-detached and terraced houses in Cumbernauld 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.
- Boilers that are old, unreliable or due for replacement
- System or regular boiler homes with an existing airing cupboard
- Combi owners who can find space for a hot water cylinder
What's included
- Capping of the gas pipe at the boiler position where you are giving up gas
- Removal of the gas boiler, flue and any loft tanks
- System flush and radiator upgrades where the design calls for them
- Free survey with heat loss calculation and cylinder siting
- Heat pump cylinder, outdoor unit and weather compensation controls
If your Cumbernauld 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
In Scotland, heat pump funding comes through Home Energy Scotland rather than the Boiler Upgrade Scheme: a grant of up to £7,500 (up to £1,500 extra for eligible rural and island homes) and an optional interest-free loan of up to £7,500. For a Cumbernauld home, apply and receive the written offer before the installation date is fixed.
There is no VAT on installing a heat pump anywhere in the UK, Scotland included, until 31 March 2027. Scottish permitted development rules and building standards apply, and the surveyor checks the unit position and any listed or conservation-area constraints.
What to budget for replacing a gas boiler with a heat pump in Cumbernauld

Designing for Cumbernauld's winters
On the shortest day Cumbernauld gets only about 6 hours 57 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 Cumbernauld: questions
How long does a heat pump survey take in Cumbernauld?
A home survey in Cumbernauld 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 you cover Airdrie as well as Cumbernauld?
Yes. We arrange surveys and installation in Airdrie, which is about 6 miles south of Cumbernauld, and across Lanarkshire.
Where would the outdoor unit go on a Cumbernauld house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Cumbernauld home.
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.
Should I have my gas meter removed?
If gas is used for nothing else, removing the meter ends the gas standing charge, which is about £108 a year at the October to December 2026 price cap. If you still cook on gas or have a gas fire, you will need to keep the supply. Meter removal is arranged through your gas supplier, usually once the heat pump is running; the pipe at the boiler position is capped during the installation.
