What to know about replacing a gas boiler with a heat pump in Glasgow
The question for a Glasgow 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.
Rear gardens and side returns in Glasgow usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours. Installers in Glasgow take out the old boiler and flue and seal the wall opening as part of the job.
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
- System or regular boiler homes with an existing airing cupboard
- Boilers that are old, unreliable or due for replacement
What's included
- Free survey with heat loss calculation and cylinder siting
- System flush and radiator upgrades where the design calls for them
- 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
- Heat pump cylinder, outdoor unit and weather compensation controls
If your Glasgow 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 Glasgow home, apply and receive the written offer before the installation date is fixed.
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 Glasgow property at survey.

Replacing a gas boiler with a heat pump in Glasgow: questions
How long does a heat pump survey take in Glasgow?
A home survey in Glasgow 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.
Can you service a heat pump in Glasgow that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Glasgow, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Glasgow?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Glasgow home states the expected time.
Is there a grant to replace a gas boiler with a heat pump?
In England and Wales, the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump that replaces a gas boiler, for eligible owners of existing homes. The MCS-certified installer applies to Ofgem and deducts the grant from your quote, and Ofgem contacts you to confirm. Scotland has separate Home Energy Scotland funding, and Northern Ireland has no dedicated homeowner grant at present.
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.
