Oil and LPG boiler replacement in Truro: what to expect
Most homes can run on a heat pump if the system is designed properly, and Truro is no different. The key is matching the heat pump and radiators to the home's heat loss.
If your home near Truro is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Rural properties near Truro 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.
- Rural and village homes off the mains gas grid
- Eligible homes in England and Wales within the higher grant window
- Owners tired of fuel deliveries and tank maintenance
What's included
- Help arranging LPG tank collection with your supplier
- Outdoor unit, heat pump cylinder, controls and radiator changes
- 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
For homes outside Truro 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 England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Truro quote.
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.

Short winter days in Truro and what they mean
On the shortest day Truro gets about 8 hours 02 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 Truro: questions
Where would the outdoor unit go on a Truro 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 Truro home.
Do you cover Falmouth as well as Truro?
Yes. We arrange surveys and installation in Falmouth, which is about 8 miles south of Truro, and across Cornwall.
Can you service a heat pump in Truro that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Truro, whoever fitted them. Tell us the make and model when you book.
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.
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.
