How Much Does a Boiler Replacement Cost?

The total cost of a boiler replacement in 2023 can vary from household to household, which means there is no simple answer to this question.

Your energy bills are higher than ever, and the cost-of-living crisis means that you want to find a way to cut your monthly costs. Questions you may be asking yourself are: can I really save money on a new boiler replacement? What is the typical cost of a new boiler unit? How much will it cost to install the boiler?

We are here to clear these questions up for you with our guide on boiler replacement costs in 2023.

If your boiler is relatively new (it is less than 5-10 years old) and is running relatively fine a boiler replacement might not be cost saving. However, if you’re having trouble with your boiler than it is likely that it is adding unnecessary costs to your energy bill each month. A boiler replacement can be financially beneficial for some households if:

• Your boiler requires regular maintenance and repairs
• Your boiler is loud or overheating
• Your house takes longer to warm up
• Your monthly energy bill is big, compared to your usage

A boiler replacement, of course, has its immediate upfront costs, however it’s long-term benefits can save your money over time.

Replacing your old boiler with a brand new, energy efficient boiler can save you up to a whopping £340 a year on your annual energy bills, which means that you can spend that money elsewhere; whether it’s putting towards a family holiday or giving yourself a little more wiggle room each month.

The price of a boiler replacement is not the same for each household, as prices can vary from where you buy your boiler from, and who installs your new boiler in your home. Important things that you should consider when pricing your boiler replacement include:

• Your location in the UK
• The type of boiler unit being installed
• The size of boiler unit
• Complexity of the installation or additional pipework required
• If you want your boiler relocated in your home
• Additional options e.g. thermostat controls
• The prices charged by your boiler installer

As we’ve mentioned previously, the cost of a boiler replacement can depend on a series of factors that influence how much you pay. According to the Energy Saving Trust, the average gas boiler installation (including thermostatic radiator valves) costs around £4,000.

We’ve broke down the different types of costs for boiler replacements, and things to consider when choosing the type of boiler for your home.

The costs of a combi boiler can cost anywhere between £1,500 and £3,500, including the installation from a gas-safe engineer. The final price of a combi boiler obviously depends on the brand of boiler that you go with and whether you are converting to a combi boiler, from another type, which may require additional pipework.

A straight combi swap is the easiest, and cost-efficient type of boiler replacement. Swapping from a conventional boiler to a combi boiler, however, can cost up to £4,500 due to the complexity of the job.

The combi boiler is an increasingly popular boiler type for households, due to its energy efficiency, compact size and instant hot water upon demand.

Due to its premium features and popularity, this means that combi boiler units tend to be a more expensive option, out of the other types of boilers. This is important to take into consideration when looking at changing to a combi boiler.

The conventional boiler is often found in many traditional, older homes due to its reliability and ability to reach large hot water demands at once.

The costs of a conventional boiler can cost anywhere between £1,500 and £3,000, including the installation from a gas-safe engineer. Due to their large systems, the complexity of a conventional boiler replacement can be more complex and often ensue additional installation costs from your local engineers.

System boilers are a popular option for homes with large spaces as they offer the same benefits as a regular boiler, with the additional benefit of being able to start large amounts of hot water. This makes them favourable in the case of your boiler breaking down, and still having access to hot water in your home.

The costs of a system boiler replacement can cost anywhere between £1,500 and £3,000 depending on the complexity of the job and boiler manufacturer.

An electric boiler converts electricity into heating (you would have never guessed) which make It highly energy efficient, despite being more expensive to run.

A electric boiler replacement can cost anywhere between £2,000 and £2,500 on average in the UK. Again, this depends on the size and the model of boiler unit, as well as the type of electric boiler that you choose i.e. combi or boiler.
