What to know about replacing an oil or LPG boiler with a heat pump in Stewarton
In Stewarton, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Cottages and farmhouses in and around Stewarton often have solid walls, so the survey looks closely at construction and draughts. If your home near Stewarton is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries.
Off-gas homes have a lot to plan when switching to a heat pump: the fuel tank, older walls, rural power supplies and higher heat loss.
- Rural and village homes off the mains gas grid
- Older oil boilers nearing the end of their life
- Detached houses and bungalows with garden space for the unit
What's included
- Removal of the oil or LPG boiler and flue
- Free survey with a detailed heat loss calculation for older construction
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Network operator notification and electrical connection
- Help arranging LPG tank collection with your supplier
Owners across Ayrshire can have oil tank removal arranged alongside a heat pump installation in Stewarton.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Stewarton 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 Stewarton property at survey.

- We commission the heat pump, show you the controls and register the installation.
Replacing an oil or LPG boiler with a heat pump in Stewarton: questions
What size heat pump does a Stewarton 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 Stewarton home.
Do you cover Kilmarnock as well as Stewarton?
Yes. We arrange surveys and installation in Kilmarnock, which is about 5 miles south of Stewarton, and across Ayrshire.
How long does installation take in Stewarton?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Stewarton home states the expected time.
Do I have to remove my oil tank?
Not always, but it should be emptied and made safe. A tank in good condition can be drained, cleaned and left in place, though most owners prefer to have it taken away to free up space. Old or damaged tanks are usually removed. Your quote says which option is included, and any remaining oil and sludge is disposed of properly.
How much is the grant for replacing an oil boiler with a heat pump?
In England and Wales, the Boiler Upgrade Scheme grant is £9,000 when an air-to-water heat pump replaces oil or LPG heating, for installations from 21 July 2026 to 31 March 2027. Otherwise the standard £7,500 applies. The installer claims it and deducts it from your quote. Scotland's Home Energy Scotland funding works differently and includes extra for eligible rural homes; Northern Ireland has no dedicated homeowner scheme at present.
