What to know about replacing an oil or LPG boiler with a heat pump in Redruth
A heat pump suits most Redruth homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Bungalows and detached houses near Redruth running on LPG can move to a heat pump, with the tank collected by the supplier. If your home near Redruth is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries.
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.
- Owners tired of fuel deliveries and tank maintenance
- Older oil boilers nearing the end of their life
- Detached houses and bungalows with garden space for the unit
What's included
- Network operator notification and electrical connection
- Oil tank draining and removal or making safe, as set out in your quote
- Help arranging LPG tank collection with your supplier
- MCS certificate and grant application in England and Wales where eligible
- Removal of the oil or LPG boiler and flue
Owners across Cornwall can have oil tank removal arranged alongside a heat pump installation in Redruth.
Grants and rules for heat pumps in England
Homes in Redruth 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.

Short winter days in Redruth and what they mean
Redruth sees roughly 8 hours 02 minutes of daylight in late December against 16 hours 25 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Replacing an oil or LPG boiler with a heat pump in Redruth: questions
How long does a heat pump survey take in Redruth?
A home survey in Redruth 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.
Do I need new radiators for a heat pump in Redruth?
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 Redruth home gives a room-by-room list.
How long does installation take in Redruth?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Redruth 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.
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.
