What to know about replacing a gas boiler with a heat pump in Ullapool
A heat pump suits most Ullapool homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Installers in Ullapool take out the old boiler and flue and seal the wall opening as part of the job. If your Ullapool home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob.
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
- Combi owners who can find space for a hot water cylinder
- Boilers that are old, unreliable or due for replacement
What's included
- Free survey with heat loss calculation and cylinder siting
- 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
- Removal of the gas boiler, flue and any loft tanks
Semi-detached and terraced houses in Ullapool often have an airing cupboard that can be reused for a heat pump cylinder.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Ullapool 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 Ullapool property at survey.
Gas boiler to heat pump costs around Ullapool
These are guide prices for the Highlands and Islands, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.

|---|---|---|
| 1–2 bedroom flat or small terrace | 4–5 kW | £10,650–£14,000 |

Installed, inc VAT: unit, cylinder, controls, minor pipework and commissioning. In Scotland, Home Energy Scotland grants of up to £7,500 and interest-free loans may reduce the cost.
Designing for Ullapool's winters
On the shortest day Ullapool gets only about 6 hours 29 minutes of daylight, with the sun around 9° 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 Ullapool: questions
Do you cover Dingwall as well as Ullapool?
Yes. We arrange surveys and installation in Dingwall, which is about 34 miles south-east of Ullapool, and across the Highlands and Islands.
Can you service a heat pump in Ullapool that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Ullapool, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Ullapool?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for an Ullapool 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.
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.
