What to know about replacing a gas boiler with a heat pump in Inverkeithing
A heat pump suits most Inverkeithing homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
If your Inverkeithing home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob. Households across Fife moving off gas can have a survey in Inverkeithing that compares running costs on realistic assumptions.
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
- 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
- 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
- Free survey with heat loss calculation and cylinder siting
Rear gardens and side returns in Inverkeithing usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours.
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 Inverkeithing 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 Inverkeithing property at survey.

Replacing a gas boiler with a heat pump in Inverkeithing: questions
How long does installation take in Inverkeithing?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for an Inverkeithing home states the expected time.
Do you cover Rosyth as well as Inverkeithing?
Yes. We arrange surveys and installation in Rosyth, which is about 2 miles west of Inverkeithing, and across Fife.
How long does a heat pump survey take in Inverkeithing?
A home survey in Inverkeithing 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.
Should I have my gas meter removed?
If gas is used for nothing else, removing the meter ends the gas standing charge, which is about £108 a year at the October to December 2026 price cap. If you still cook on gas or have a gas fire, you will need to keep the supply. Meter removal is arranged through your gas supplier, usually once the heat pump is running; the pipe at the boiler position is capped during the installation.
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.
