You must have lots of questions. We’ve answered some of the most commonly-asked questions about replacement boilers and grants for boilers here, but please speak to the team if you have any more.

How much does it cost to install a new gas boiler?

Based on current prices, the average cost of having a boiler replaced privately is £1,800. To get a tailored quote, complete this easy-to-fill-out form and speak to our expert team.

What is the best boiler for my home?

Unfortunately, there is no one-size-fits-all answer to this question. The best boiler for you will depend on a number of factors, including the size of your home, the number of people living there, your hot water usage, and your budget. We recommend speaking to our experts for more in-depth advice on what boiler would best suit your property’s needs.

What will replace gas boilers in the future?

As part of the government’s commitment to reach net zero carbon emissions by 2050, gas boilers are being slowly phased out. Hydrogen boilers, ground source heat pumps, air source heat pumps and solar energy installations are the new alternatives.

Who qualifies for a new boiler grant?

To be eligible to receive a heating grant to cover the cost of replacing your boiler, you must live in either England or Wales, someone living in the property must be the homeowner, your current boiler must be non-condensing, and you must be in receipt of one of the qualifying benefits. Once we’ve confirmed that you are eligible to receive the grant, one of our Gas Safe registered surveyors will come to the property to carry out a free, no-obligation survey.
