Oil and LPG boiler replacement in Largs: what to expect
Most homes can run on a heat pump if the system is designed properly, and Largs is no different. The key is matching the heat pump and radiators to the home's heat loss.
If your home near Largs is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Cottages and farmhouses in and around Largs 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
- Rural and village homes off the mains gas grid
- Older oil boilers nearing the end of their life
What's included
- Oil tank draining and removal or making safe, as set out in your quote
- Help arranging LPG tank collection with your supplier
- Network operator notification and electrical connection
- Free survey with a detailed heat loss calculation for older construction
- Outdoor unit, heat pump cylinder, controls and radiator changes
Rural properties near Largs usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Largs 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 Largs: questions
Where would the outdoor unit go on a Largs 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 Largs home.
Do you cover Ardrossan as well as Largs?
Yes. We arrange surveys and installation in Ardrossan, which is about 10 miles south of Largs, and across Ayrshire.
Can you service a heat pump in Largs that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Largs, whoever fitted them. Tell us the make and model when you book.
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.
Is a heat pump cheaper to run than oil?
It depends on oil prices, your home's insulation, the flow temperature and your electricity tariff, so there is no single answer. At the October to December 2026 price cap, a heat pump with a seasonal efficiency of 3.0 delivers heat for about 8.8p per kWh, and at 3.5 about 7.5p. Compare that with your oil cost per kWh of heat, allowing for your boiler's efficiency; the survey estimate gives a figure for your home.
