Questions people ask about boilers
How much do boilers cost in the UK?
Boilers in the UK cost between £1,350 and £6,134 installed, depending on system size and where you live. Across the 160 towns we price, the median for a mid-range system is around £2,720 including installation and VAT (modelled estimate).
Is there a grant for boilers in the UK?
There is no general government grant for replacing a gas or oil boiler with a new one. Lower-income households may get help through Warmer Homes Scotland, Nest in Wales or the Affordable Warmth Scheme in Northern Ireland, and the Boiler Upgrade Scheme offers up to £7,500 if you switch to a heat pump in England or Wales.
How long is the payback period in the UK?
The estimated payback period for boilers in the UK is typically around 14 years, based on estimated savings of up to £202 a year for a typical home. Actual payback depends on your property size, boiler efficiency and gas tariff.
Do I need planning permission for boilers?
Most boilers installations fall under permitted development rights and do not require planning permission. However, listed buildings, conservation areas and flats may need approval from your local council. Always check with your local planning authority before installation.
How do I find a good installer in the UK?
