Gas boiler to heat pump for Cumnock homes
Homes around Cumnock range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Many gas-heated homes in Cumnock have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder. Rear gardens and side returns in Cumnock usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours.
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.
- Combi owners who can find space for a hot water cylinder
- Households ready to give up gas entirely and drop the standing charge
- 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
- Heat pump cylinder, outdoor unit and weather compensation controls
- 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
Semi-detached and terraced houses in Cumnock often have an airing cupboard that can be reused for a heat pump cylinder.
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 Cumnock 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 Cumnock property at survey.

Designing for Cumnock's winters
On the shortest day Cumnock gets only about 7 hours 04 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 Cumnock: questions
What size heat pump does a Cumnock home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Cumnock home.
How long does installation take in Cumnock?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Cumnock home states the expected time.
Can you service a heat pump in Cumnock that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Cumnock, whoever fitted them. Tell us the make and model when you book.
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.
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.
