What is the Boiler Replacement Grant?

The boiler replacement grant is part of the UK government-sponsored initiatives, where qualifying households get free boiler replacement. This thoughtful endeavour is designed with the aim of providing efficient and affordable heating to eligible homes.

As boilers get old, they lose their efficiency. In fact, boilers over seven years old lose about 65% of their efficiency which translates to a loss of 35p from every pound spent on heating. On the other hand, a new A-rated boiler operating at a minimum of 90% efficiency will reduce that wastage to at least 10p per pound. Not only does it significantly reduce energy waste, it also saves money on heating bills.

As a result, this free boiler replacement scheme is aimed at helping homeowners save money on energy bills by providing households with highly efficient boilers. Just as the name suggests, it is a grant, meaning you won't have to pay it back.

Who Qualifies for Free Boiler Replacement?
