The cost of a new boiler is a subject most UK citizens would rather not think about. But let's face it, if your current boiler leaves a lot to be desired, you'll be left looking for a solid replacement.
A pesky situation like this is bound to raise a few questions. How much does a new boiler cost? What does it cost to fit a boiler? What exactly is the average cost of a boiler replacement in the UK?
There’s no need to look any further for the answers to these questions and more -we’ve got you covered. In this article, we'll walk you through everything you need to know about the cost of your new boiler and help you save some money along the way.
What defines the cost of a boiler replacement?
The cost of a new boiler depends on several factors, such as:
- The type of boiler you wish to install
- The boiler manufacturer you choose
- The type of model you want
- The type of fuel your new boiler will use
Furthermore, as a gas boiler must be installed by a Gas Safe registered heating engineer, you'll also need to take installation costs into account. Let's take a deep dive into these factors and find out what the cost of a new boiler looks like in the UK.
New boiler costs: different types of boilers
The cost to replace a boiler is highly dependent on the type of boiler you wish to install. There are several types of boilers on the market, like the traditional conventional boiler, the speedy combi boiler, and the conveniently sized system boiler.
Each boiler has its own pros, and price class. For example, the cost of a new combi boiler differs from that of a system boiler replacement. It's important to keep these differences in mind when deciding on a brand new boiler.
Let's look into each type of boiler and find out what's different.
New combi boiler cost
The cost of a combi boiler usually ranges from £500 to £2,000. Please keep in mind that this excludes the cost of installing a combi boiler. If you wish to have your new boiler fitted as well, be mindful of additional fees ranging from £1,600 to £3,500.
How much does a new combi boiler cost exactly, then? That depends on several factors, such as the manufacturer, model and fuel. You usually pay a higher price for increased performance and a prolonged warranty period as well. The size of your home and the energy it requires also play a major role.
In addition, you must consider the specific boiler replacement situation. For example:
|Boiler Replacement Situation||Estimated Cost|
|Replace an old combi boiler with a new one, in the same location||£1,700|
|Replace a system boiler with a new combi boiler, including hot water cylinder removal||£2,500|
|Replace a regular boiler with a new combi boiler, including hot water storage and cold water tank removal||£3,500|
An excellent way to lower your boiler replacement costs is by getting several quotes from heating engineers near you. They will give you accurate quotes for the required work, and you can pick the price and solution that best suits you.

Cost of replacing a conventional boiler with a combi
A conventional boiler is a traditional heating device that most are familiar with. However, in some cases, it may be worth replacing your conventional boiler with a brand new combi boiler. While this is definitely possible, you should account for several additional costs, such as:
- The cost to remove the hot water storage tank (£100 to £150 on average)
- The cost of the feed tank removal (£200 to £300 on average)
While the additional costs of replacing a conventional boiler with a combi boiler may seem daunting at first, changing from one to the other is often a worthwhile investment. A combi boiler offers a wide range of benefits, such as more efficiency, less maintenance needed and far more convenient size. You could even get a loft conversion after removing the big water tanks.
If you combine the regular costs of a boiler replacement with these additional costs, you can expect to pay approximately £1,900 to £3,950 for your new boiler. The costs of a new combi boiler and installation combined with the replacement round up to around £3,500 to £7,450.
System boiler cost
You can expect to pay between £500 to £2,500 for a new system boiler. You may also be charged additional fees ranging from £1,600 to £3,500 for getting your system boiler fitted.
To find out exactly how much a system boiler replacement costs, we'll have to look at several other factors as well. The manufacturer, model and fuel play a major role, but the size of your home, your home's energy needs, the performance, and the warranty length of your new system boiler affect the costs too.
Conventional boiler cost
A conventional boiler, also known as a regular boiler, is the oldest among the three types of heating systems covered in this article. As in the previous cases, installation and fittings fees could add between £1,600 and £3,500 to the conventional boiler unit price. Just the conventional boiler unit would cost around £500 to £2,750.
Similar to combi and system boilers, the brand, model, power, and length of the warranty of a regular boiler can cause price variations. For instance, if you own a large 7-bedroom house, you need a powerful boiler. As a rule of thumb, the larger a property, the bigger (more powerful) the boiler it needs.
New boiler costs: the best manufacturers listed
While the type of boiler you choose plays a big part in determining the cost of your boiler's replacement, the manufacturer you pick isn't something to ignore either. Below, we've listed the best boiler manufacturers and the new boiler costs they charge.
|Brand||Combi boiler prices||Regular Boiler Prices||System Boiler Prices|
|Alpha||£690 – £1,033||£710 – £810||£788 – £983|
|Baxi||£549 – £1,307||£663 – £991||£711 – £1,011|
|Ideal||£714 – £1,323||£712 – 2,796||£785 – 1,201|
|Worcester Bosch||£730 – £2,475||£814 – £2,300||£899 – £2,209|
|Vaillant||£907 – £1,703||£792 – £1,533||£894 – £2,264|
|Viessmann||£800 – £1,600||£845 – £1,200||£995 – £1,650|
So, the cost of a new boiler from one of these manufacturers is likely between £700 and £2,000. However, it's possible to find them for as little as £550.

New boiler costs: different boiler models
Many household appliances offer product variations. Boilers are no exception and come in different types with varying price classes. Let's take a closer look at what you can expect to pay.
|Combi boiler||System boiler||Conventional boiler|
|Budget models||£500 – £900||£500 – £900||£500 – £900|
|Mid-range models||£900 – £1,200||£900 – £1,300||£900 – £1,300|
|Premium models||£1,000 – £2,000||£1,300 – 2,000||£1,300 – £2,750|
Please keep in mind that these numbers don't include the installation costs. Boiler replacement costs in the UK are always dependent on your specific circumstances and needs.
Finally, the fuel your new boiler will use has an impact on the cost of installing a new boiler. We will focus on the types of fuel most used in the UK:
Below we take a closer look at each one.
New gas boiler cost
Gas-fuelled boilers are the most common boilers in the UK. They can be either combi, system, or conventional boilers. Including installation, a new gas boiler costs between £1,000 and £3,750, on average. However, prices could stretch to £4,000 and beyond.
Another indicator to be mindful of is gas boilers running costs. Considering the sharp increase in fuel prices in April 2022 and the heat demand for a typical household, running a gas boiler may cost you around £984 per year.

We can connect you with installers who can assess your home and offer quotes based on your specific needs. By comparing these quotes, you can get the best prices from Gas Safe, and OFTEC registered engineers.
New oil boiler cost
Oil boilers are the most popular heating alternative for homes that aren't connected to the gas network. Prices for one of these units start at £1,000 and can go well above £4,000. In total, new replacement oil boiler prices, including installation, could cost between £2,500 and £4,500.
Furthermore, running an oil boiler could cost around £1,250 per year, about £250 more expensive than using gas to heat your house.
Electric boiler cost
There are several variations of electric boilers on the market, such as the electric combi boiler, the electric storage boiler, the electric CPSU boiler, the Dry Core Storage boiler, and the solar-compatible boiler.
The average price of an electric boiler can range from £650 to 2,500. Moreover, installation costs will likely fall between £1,600 and £3,500.
Electric boilers are a worthwhile purchase for homes without gas and people looking to lower their carbon footprint. However, you should consider that most electricity in the UK is generated by burning fossil fuels. Additionally, it is much more expensive than gas and oil.
Running costs of an electric boiler in a typical household could be as high as £3,000. Of course, it would be less for smaller 1 or 2-bedroom homes.
Is the government giving grants for new boilers?
Let's be honest here: a new boiler will not be cheap. However, there is a range of support, grants and schemes available to help UK citizens save on their new boiler. Still, you have to match certain criteria to be eligible.
Eligible homeowners can expect to have the costs of their new boilers partially covered and sometimes even get a boiler for free. Curious if you qualify? Then take a look at our article Free boilers and the Energy Company Obligation.
New boiler installation cost
So far, we've taken a close look at the cost of a new boiler. However, the new boiler installation costs also need to be considered. Let's examine them in more detail.
How much does a boiler installation cost, exactly? That's hard to say. On average, the cost of boiler installations in the UK ranges from £1,600 to £3,500. This fee accounts for the person-hours and the complexity of the installation.
The disparity between the costs is mainly caused by the varying labour costs in different areas and the complexity of the installation. For example, a new boiler in London costs more than a new oil boiler in Northern Ireland. Plus, a straightforward installation is cheaper than a complex job.
Summary: average cost of boiler replacement
Let's summarise what we've found out so far. The average cost of a new boiler is decided by a few factors: the model, the manufacturer, the performance, the warranty, and the size (output rating) of the boiler. Most people will end up paying between £500 and £2,750 for their new boiler.
Furthermore, the average boiler installation cost is decided by your local labour costs, the complexity of the job and the number of person-hours needed for the installation. The average cost to replace a boiler usually comes down to somewhere between £1,600 and £3,500.
Then what exactly are the average costs of a new boiler and the installation combined? That will most likely be somewhere between £2,100 and £6,250.
However, do remember that it may be possible to cut down on the costs with a grant. In the end, the best way to get an idea of what you'll be paying and obtain the best prices is to get several comparison quotes from Gas Safe registered engineers near you.
