Oil and LPG boiler replacement in Falmouth: what to expect
A heat pump suits most Falmouth homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
If your home near Falmouth is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Owners across Cornwall can have oil tank removal arranged alongside a heat pump installation in Falmouth.
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
- Detached houses and bungalows with garden space for the unit
- Eligible homes in England and Wales within the higher grant window
What's included
- MCS certificate and grant application in England and Wales where eligible
- Help arranging LPG tank collection with your supplier
- 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
Cottages and farmhouses in and around Falmouth often have solid walls, so the survey looks closely at construction and draughts.
Grants and rules for heat pumps in England
Homes in Falmouth can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.
Guide prices for replacing an oil or LPG boiler with a heat pump in Falmouth
The ranges below are typical installed prices for homes in Cornwall, including VAT. A survey sets the exact figure, because two similar-looking houses in Falmouth can need quite different radiators and pipework.
| Home | Typical size | Installed guide price | After £9,000 grant |
|---|---|---|---|
| 1–2 bedroom flat or small terrace | 4–5 kW | £9,800–£12,900 | £800–£3,900 |

Installed, inc VAT: unit, cylinder, controls, minor pipework and commissioning. The £9,000 Boiler Upgrade Scheme figure applies to oil and LPG replacements in England and Wales installed from 21 July 2026 to 31 March 2027.
Winter daylight and heating in Falmouth
On the shortest day Falmouth gets about 8 hours 03 minutes of daylight, and the winter sun reaches only around 16° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Replacing an oil or LPG boiler with a heat pump in Falmouth: questions
Where would the outdoor unit go on a Falmouth 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 Falmouth home.
Do I need new radiators for a heat pump in Falmouth?
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 Falmouth home gives a room-by-room list.
How long does installation take in Falmouth?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Falmouth home states the expected time.
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.
