Oil and LPG boiler replacement in Launceston: what to expect
A heat pump suits most Launceston homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Cottages and farmhouses in and around Launceston often have solid walls, so the survey looks closely at construction and draughts. Rural properties near Launceston usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.
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.
- Eligible homes in England and Wales within the higher grant window
- Detached houses and bungalows with garden space for the unit
- Owners tired of fuel deliveries and tank maintenance
What's included
- Outdoor unit, heat pump cylinder, controls and radiator changes
- 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
- Help arranging LPG tank collection with your supplier
Bungalows and detached houses near Launceston running on LPG can move to a heat pump, with the tank collected by the supplier.
Grants and rules for heat pumps in England
Homes in Launceston 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.
Oil and LPG boiler replacement costs around Launceston

Replacing an oil or LPG boiler with a heat pump in Launceston: questions
Do you cover Liskeard as well as Launceston?
Yes. We arrange surveys and installation in Liskeard, which is about 13 miles south of Launceston, and across Cornwall.
Can you service a heat pump in Launceston that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Launceston, whoever fitted them. Tell us the make and model when you book.
How soon can you survey a home in Launceston?
Survey dates depend on how busy installers are in Cornwall. We offer the next available dates when you enquire and confirm them in writing.
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.
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.
