What to know about replacing a gas boiler with a heat pump in Port Glasgow
Most homes can run on a heat pump if the system is designed properly, and Port Glasgow is no different. The key is matching the heat pump and radiators to the home's heat loss.
Rear gardens and side returns in Port Glasgow usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours. Many gas-heated homes in Port Glasgow have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder.
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
- Boilers that are old, unreliable or due for replacement
- System or regular boiler homes with an existing airing cupboard
What's included
- Free survey with heat loss calculation and cylinder siting
- System flush and radiator upgrades where the design calls for them
- Heat pump cylinder, outdoor unit and weather compensation controls
- Capping of the gas pipe at the boiler position where you are giving up gas
- Removal of the gas boiler, flue and any loft tanks
Households across Renfrewshire and Inverclyde moving off gas can have a survey in Port Glasgow 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 a Port Glasgow 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 Port Glasgow property at survey.

Replacing a gas boiler with a heat pump in Port Glasgow: questions
Do you cover Greenock as well as Port Glasgow?
Yes. We arrange surveys and installation in Greenock, which is about 3 miles west of Port Glasgow, and across Renfrewshire and Inverclyde.
Where would the outdoor unit go on a Port Glasgow house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Port Glasgow home.
How soon can you survey a home in Port Glasgow?
Survey dates depend on how busy installers are in Renfrewshire and Inverclyde. We offer the next available dates when you enquire and confirm them in writing.
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.
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.
