How Much Does It Cost to Replace a Combi Boiler?
If you’re thinking about replacing your combi boiler, you’re probably wondering how much it will set you back. The cost can vary depending on factors like the brand, model, and how complex the installation is.
For a straightforward swap—where you’re replacing an old combi boiler with a new one in the same location—you’re looking at anywhere between £2,500 and £4,000. This price usually includes both the cost of the new boiler and the installation.
If your installation is more complicated, such as switching from a system boiler to a combi boiler, the price will likely be higher. These conversions often require extra work, like removing an old water tank or adjusting your plumbing, so you can expect to pay around £4,000 or more for the full job.
While replacing a boiler can be a big investment, it can also lead to lower energy bills and improved efficiency—so it’s worth considering your long-term savings too!
Government Grants and Schemes to help with Boiler Replacement Costs
Replacing a boiler can be expensive, but the good news is that there are government grants and schemes available to help reduce the cost—especially if you’re looking to make your home more energy-efficient. Here are some of the key schemes you might be able to take advantage of:
Boiler Upgrade Scheme (BUS)
This scheme is designed to encourage homeowners to switch from traditional fossil fuel heating systems to greener, low-carbon alternatives like heat pumps or biomass boilers. If you’re eligible, you could receive a grant of up to £7,500 towards the installation of an air source or ground source heat pump, helping to lower your long-term energy costs while reducing your carbon footprint.

Energy Company Obligation (ECO) Scheme
If you’re on a lower income or receive certain benefits, you might qualify for support through the ECO scheme. This initiative is aimed at improving energy efficiency in homes by funding measures such as boiler replacements and insulation. It’s worth checking if you’re eligible, as it could significantly cut down your costs.
Local Authority Flex (LA Flex)
This is an extension of the ECO scheme, giving local councils more flexibility to set their own eligibility criteria. Even if you don’t qualify for the standard ECO scheme, your local authority might still be able to offer support if you need help making your home more energy-efficient. Availability and criteria can vary depending on your council, so it’s always a good idea to check with them directly.

It’s worth looking into—many homeowners don’t realise they could get financial support for upgrading their heating system!
