Gas, oil or heat pump for a Cumbrian home
The right choice depends mostly on what fuel reaches your house.
Oil
Common in villages and farms with no gas main.
Needs a tank in good order, and running costs follow the oil price.
Heat pump
Worth a look for well-insulated homes, especially those on oil.
Needs outside space and may need bigger radiators. A survey tells you if it suits.
Typical 2026 costs
UK cost guides for 2026 put a fitted gas combi at £1,800 to £3,000. A new oil boiler runs higher, from £2,200 to £5,500 with an average near £3,300. Your quote depends on the boiler, the flue and any pipework changes.

Boiler Upgrade Scheme
Homes in England and Wales can get £7,500 off an air source or ground source heat pump through the Boiler Upgrade Scheme.
Until March 2027 there is an extra £1,500 if your home is heated by oil or LPG and has no mains gas, which takes the grant to £9,000. An MCS-certified installer applies for you and takes it off the price. The scheme is run by Ofgem.

A straight swap is often done in a day or two.
Moving the boiler, changing fuel, a new flue or a heat pump all take longer. The installer gives you a timescale after the survey.
Questions people ask
How much is a new oil boiler?
UK guides for 2026 give £2,200 to £5,500 fitted, with an average of about £3,300. A new tank or flue adds to that.
Can I get a grant?
Not for a new gas or oil boiler in most cases. For a heat pump, the Boiler Upgrade Scheme gives £7,500, or £9,000 until March 2027 for homes on oil or LPG with no gas main.
Combi or system?
A combi suits smaller homes with one bathroom. Bigger homes, or ones where two showers run at once, often do better with a system boiler and a cylinder.
How long is the warranty?
It depends on the maker and model, often 5 to 10 years. Most need the boiler registered and serviced every year to keep it.
