Oil and LPG boiler replacement for Helensburgh homes
Most homes can run on a heat pump if the system is designed properly, and Helensburgh is no different. The key is matching the heat pump and radiators to the home's heat loss.
For homes outside Helensburgh reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance. Owners across Argyll and Bute can have oil tank removal arranged alongside a heat pump installation in Helensburgh.
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
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Help arranging LPG tank collection with your supplier
- Removal of the oil or LPG boiler and flue
- Network operator notification and electrical connection
- Free survey with a detailed heat loss calculation for older construction
Rural properties near Helensburgh 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 Helensburgh 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.

Designing for Helensburgh's winters
On the shortest day Helensburgh gets only about 6 hours 57 minutes of daylight, with the sun around 11° up at noon. Long Scottish winters mean the heat pump runs for much of the year, so careful sizing, good controls and correctly sized radiators make a real difference.

Replacing an oil or LPG boiler with a heat pump in Helensburgh: questions
Do I need new radiators for a heat pump in Helensburgh?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Helensburgh home gives a room-by-room list.
How long does installation take in Helensburgh?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Helensburgh home states the expected time.
How long does a heat pump survey take in Helensburgh?
A home survey in Helensburgh 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.
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.
Do I have to remove my oil tank?
Not always, but it should be emptied and made safe. A tank in good condition can be drained, cleaned and left in place, though most owners prefer to have it taken away to free up space. Old or damaged tanks are usually removed. Your quote says which option is included, and any remaining oil and sludge is disposed of properly.
