Oil and LPG boiler replacement for Dunoon homes
The question for a Dunoon 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 Dunoon usually have garden space for the outdoor unit, sited away from windows and sheltered where possible. Cottages and farmhouses in and around Dunoon 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.
- 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
- Outdoor unit, heat pump cylinder, controls and radiator changes
- 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
For homes outside Dunoon reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance.
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 Dunoon 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.
What to budget for replacing an oil or LPG boiler with a heat pump in Dunoon
The ranges below are typical installed prices for homes in Argyll and Bute, including VAT. A survey sets the exact figure, because two similar-looking houses in Dunoon can need quite different radiators and pipework.
| Home | Typical size | Installed guide price |
|---|---|---|
| 1–2 bedroom flat or small terrace | 4–5 kW | £10,250–£13,500 |
| 2–3 bedroom terrace or semi | 5–7 kW | £11,350–£14,600 |
| 3 bedroom semi or small detached | 6–9 kW | £12,950–£16,750 |
| 4 bedroom detached | 8–12 kW | £15,100–£19,450 |
| 5+ bedroom or larger older house | 11–16 kW | £17,800–£24,300 |
Installed, inc VAT: unit, cylinder, controls, minor pipework and commissioning. In Scotland, Home Energy Scotland grants of up to £7,500 and interest-free loans may reduce the cost.
How long is the heating season in Dunoon?
On the shortest day Dunoon 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.
How installation works in Dunoon
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Dunoon home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Dunoon is in an area we cover by arrangement, so survey dates and any travel costs are confirmed individually in your quote.
Replacing an oil or LPG boiler with a heat pump in Dunoon: questions
Where would the outdoor unit go on a Dunoon 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 Dunoon home.
Do I need new radiators for a heat pump in Dunoon?
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 Dunoon home gives a room-by-room list.
Can you service a heat pump in Dunoon that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Dunoon, whoever fitted them. Tell us the make and model when you book.
How much is the grant for replacing an oil boiler with a heat pump?
In England and Wales, the Boiler Upgrade Scheme grant is £9,000 when an air-to-water heat pump replaces oil or LPG heating, for installations from 21 July 2026 to 31 March 2027. Otherwise the standard £7,500 applies. The installer claims it and deducts it from your quote. Scotland's Home Energy Scotland funding works differently and includes extra for eligible rural homes; Northern Ireland has no dedicated homeowner scheme at present.
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.
