What to know about replacing an oil or LPG boiler with a heat pump in Port Glasgow
Homes around Port Glasgow range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Owners across Renfrewshire and Inverclyde can have oil tank removal arranged alongside a heat pump installation in Port Glasgow. For homes outside Port Glasgow reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance.
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.
- Older oil boilers nearing the end of their life
- Rural and village homes off the mains gas grid
- Owners tired of fuel deliveries and tank maintenance
What's included
- Removal of the oil or LPG boiler and flue
- Oil tank draining and removal or making safe, as set out in your quote
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Free survey with a detailed heat loss calculation for older construction
- Help arranging LPG tank collection with your supplier
Cottages and farmhouses in and around Port Glasgow often have solid walls, so the survey looks closely at construction and draughts.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Port Glasgow 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.
There is no VAT on installing a heat pump anywhere in the UK, Scotland included, until 31 March 2027. Scottish permitted development rules and building standards apply, and the surveyor checks the unit position and any listed or conservation-area constraints.

Replacing an oil or LPG boiler with a heat pump in Port Glasgow: questions
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.
Can you service a heat pump in Port Glasgow that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Port Glasgow, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Port Glasgow 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 Port Glasgow home.
What happens with a leased LPG tank?
Leased LPG tanks belong to the supplier, so the supplier arranges collection. Check your contract for notice periods and any charges before you fix a date. We time the switchover so you are not left without heating, and once the heat pump is commissioned the supplier can empty and remove the tank. Bottled LPG cylinders are simply returned.
Will I need bigger radiators in an older cottage or farmhouse?
Often in some rooms, because thick solid walls and older windows lose more heat, and heat pumps work at lower water temperatures than oil boilers. The survey checks each room. Rooms with high ceilings or large windows are common candidates for a larger radiator. Where swapping radiators is impractical, a high-temperature unit can be considered, with lower efficiency as the trade-off.
