Before you book: replacing an oil or LPG boiler with a heat pump in Grangemouth
The question for a Grangemouth home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Rural properties near Grangemouth usually have garden space for the outdoor unit, sited away from windows and sheltered where possible. Cottages and farmhouses in and around Grangemouth often have solid walls, so the survey looks closely at construction and draughts.
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.
- Owners tired of fuel deliveries and tank maintenance
- Detached houses and bungalows with garden space for the unit
- Older oil boilers nearing the end of their life
What's included
- Help arranging LPG tank collection with your supplier
- Oil tank draining and removal or making safe, as set out in your quote
- Free survey with a detailed heat loss calculation for older construction
- Network operator notification and electrical connection
- Removal of the oil or LPG boiler and flue
If your home near Grangemouth is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries.
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 Grangemouth home, apply and receive the written offer before the installation date is fixed.
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 Grangemouth: questions
Can you service a heat pump in Grangemouth that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Grangemouth, whoever fitted them. Tell us the make and model when you book.
How soon can you survey a home in Grangemouth?
Survey dates depend on how busy installers are in Stirling, Falkirk and Clackmannanshire. We offer the next available dates when you enquire and confirm them in writing.
What size heat pump does a Grangemouth 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 Grangemouth 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.
