Before you book: replacing a gas boiler with a heat pump in Aberdeen
A heat pump suits most Aberdeen homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Installers in Aberdeen take out the old boiler and flue and seal the wall opening as part of the job. If your Aberdeen 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.
- Boilers that are old, unreliable or due for replacement
- 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
- Heat pump cylinder, outdoor unit and weather compensation controls
- Removal of the gas boiler, flue and any loft tanks
- Free survey with heat loss calculation and cylinder siting
- 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
Households across Aberdeenshire and Moray moving off gas can have a survey in Aberdeen that compares running costs on realistic assumptions.
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 an Aberdeen 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 Aberdeen property at survey.
Gas boiler to heat pump costs around Aberdeen
The ranges below are typical installed prices for homes in Aberdeenshire and Moray, including VAT. A survey sets the exact figure, because two similar-looking houses in Aberdeen can need quite different radiators and pipework.
| Home | Typical size | Installed guide price |
|---|---|---|
| 1–2 bedroom flat or small terrace | 4–5 kW | £9,800–£12,900 |
| 2–3 bedroom terrace or semi | 5–7 kW | £10,800–£13,900 |
| 3 bedroom semi or small detached | 6–9 kW | £12,350–£15,950 |
| 4 bedroom detached | 8–12 kW | £14,400–£18,550 |
| 5+ bedroom or larger older house | 11–16 kW | £17,000–£23,200 |
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.
How long is the heating season in Aberdeen?
On the shortest day Aberdeen gets only about 6 hours 40 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.
How installation works in Aberdeen
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Aberdeen home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Replacing a gas boiler with a heat pump in Aberdeen: questions
How long does installation take in Aberdeen?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for an Aberdeen home states the expected time.
Do you cover Portlethen as well as Aberdeen?
Yes. We arrange surveys and installation in Portlethen, which is about 6 miles south of Aberdeen, and across Aberdeenshire and Moray.
What size heat pump does an Aberdeen 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 Aberdeen home.
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.
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.
