How much is a new boiler? | |||
---|---|---|---|
Type of boiler / Fuel source | Cost excl. installation | Cost inc. installation (£1,000 - £1,500) | Average inc. installation |
Combi | £500 - £3,000 | £1,500 - £4,500 | £3,000 |
System | £580 - £3,500 | £1,580 - £5,000 | £3,290 |
Conventional | £600 - £3,500 | £1,600 - £5,000 | £3,050 |
Electric | £590 - £2,500 | £1,590 - £4,000 | £2,795 |
Biomass | £4,000 - £12,000 | £6,000 - £21,000 | £13,500 |
Drawing from our experience, the average new boiler cost ranges from £500 - £12,000 before installation. Where your new boiler falls within this range largely depends on the type of boiler you go for. The table above summarises these cost differences but it should be noted it can only provide estimates as prices can vary due to location and household needs.
The cost range for a new boiler varies so much, for a few reasons. Firstly, the brand and size of the boiler you choose can make a difference. Well-known brands such as Worcester Bosch or Viessmann can charge more simply for their name.
Fuel types and the size of your boiler can also impact cost, as the larger (more powerful) it is can often mean it is more expensive. This is, however, something an experienced installer can help with, as lesser-known brands can sometimes offer the same performance level of boiler, just without the expensive brand attached!
The second major cost factor to be aware of is the complexity of your installation. If you wish to change from one boiler type to another (e.g. combi to system) it can take extra work and additional parts to complete the job. In contrast, if you need a straightforward replacement (combi to combi) it will likely be very quick and easy, taking your installer less time and costing less.
Other elements you might end up paying for include new parts, a cleaning of your pipework or even basic elements like an extended warranty.
The cost of a new boiler will be affected by potential extras and installation costs, which vary by installer.
That’s why it’s best to compare several heating engineers in your area.

New boiler type | Price range | Average inc. installation |
---|---|---|
Combi | £500 - £3,000 | £3,000 |
Combi boilers are the most popular boiler type in the UK since they only require a single unit to operate. The compact size makes combi boilers best suited to small-to-medium-sized homes with precious space. As aforementioned, combi boiler prices range from £500 to £3,000.
Replacing a conventional, aka regular, boiler with a combi will typically cost between £1,500 - £4,500.
This type of replacement might be preferable if you wish to improve home efficiency as combi boilers can provide an instant supply of mains pressure water for heating and hot water.
On the other hand, conventional boiler systems include a cold water tank, usually kept in the loft, that feeds water to a hot water cylinder. These additional units require more space in your home and usually won’t reach the same flow rates as a modern combi boiler.
However, it’s important to remember that this kind of replacement requires additional parts and labour to restructure the pipework to make way for a new boiler type, as well as the removal of the cold water tank and hot water cylinder. This will likely add a day's work to the installation job, meaning it will take around 2 days altogether.
Conventional - combi boiler replacement | Average price range |
---|---|
New combi boiler | £500 - £3,000 |
Installation costs inc. additional parts and labour | £1,000 - £1,500 |
Average total replacement cost | £3,000 |
Upgrading your combi boiler can be a costly task, but it’s easier to manage when you know what’s involved. We’ve broken down each type of combi boiler installation in the table below, so you can get a clear idea of the typical costs.
New boiler type | Cost excluding installation | Cost including installation |
---|---|---|
Combi to combi | £500 - £3,000 | £1,500 - £4,500 |
Combi to system | £580 - £3,500 | £1,580 - £5,000 |
Combi to conventional | £600 - £3,500 | £1,100 - £5,000 |
Costs for a new boiler replacement can vary widely. This can be due to the boiler model and brand, the installation complexity and any additional parts or work your system might require. It’s important to get expert advice from a qualified engineer to ensure you get quotes specific to your needs.
It’s also crucial to remember that the cost of installation will often be in addition to the boiler cost. By being informed about the costs upfront, you can make a well-informed decision that aligns with your budget and heating needs.
The complexity of the installation will have considerable bearings on the overall replacement boiler cost. That’s why it’s a good idea to receive multiple quotes from engineers and compare them beforehand to ensure you get the best price.
Comparing heating engineers can take hours and be very stressful when done alone.

New boiler type | Price range | Average inc. installation |
---|---|---|
Electric | £590 - £2,500 | £2,795 |
Most boiler types, including combi boilers and system boilers, can be powered by electricity, rather than gas or oil. This makes electric boilers a popular alternative for homes off of the gas grid. What’s more, the best electric boilers come with efficiency ratings close to 100%, meaning you can get the most out of your energy.
Electric boilers are generally thought of as an environmentally friendly boiler option, and while they don’t release any carbon emissions or toxic gases while they operate, the supply of electricity itself is mostly generated from burning natural gas. The skyrocketing cost of natural gas also in part accounts for the high running costs of an electric boiler and electric combi boilers.
You can avoid this by signing up with a renewable energy provider, there are a number to choose from including Octopus Energy, Ecotricity, Good Energy and Bulb. You can also take advantage of free, renewable solar energy options such as solar panels and solar thermal which you can combine with your electric heating system. In addition, it is also worth considering support in the form of solar panel grants and schemes available in the UK.
GreenMatch is committed to the UK’s transition to renewable, low-carbon heating. As these new technologies emerge, it is clear that the upfront costs make them unattainable to many UK homes.
Therefore, switching to a new, energy-efficient boiler is the most cost-smart strategy to reduce your overall carbon footprint until these new technologies become more financially viable.
New boiler type | Price range | Average inc. installation |
---|---|---|
System | £580 - £3,500 | £3,290 |
System boilers, alongside a hot water cylinder, keep a constant supply of hot water storage provided by the local mains supply. This makes a system boiler suitable for medium-to-large homes with high energy demands.
New boiler type | Price range | Average inc. installation |
---|---|---|
Conventional | £600 - £3,500 | £3,050 |
Conventional boilers are the more traditional boiler types, typically found in older homes and buildings. Due to our practical knowledge, we know that out of all boiler types, these will require the most space. This is because a conventional boiler requires a hot water cylinder and a cold water tank. Therefore, they are best for medium-to-large homes.
The average cost of a boiler replacement will come down to several key factors, including:
How much will these factors bear on your new boiler costs? The best way to know is by consulting local installers and receiving quotes for their services, including boiler supply and installation.

Boiler manufacturers base their average new boiler costs on various factors and there can be some variance between them. These include the additional features that come with the boiler, the reputation of the brand, and the overall quality of the model.
Below you can see the usual price ranges for each manufacturer, per boiler type:
Manufacturer | Combi boiler price range | System boiler price range | Conventional boiler price range |
---|---|---|---|
Worcester Bosch | £800 - £2,900 | £1,000 - £2,500 | £800 - £2,400 |
Vaillant | £900 - £1,700 | £900 - £2,170 | £850 - £1,700 |
Viessmann | £850 - £1,450 | £1,110 - £1,400 | £890 - £1,450 |
Ideal | £800 - £1,400 | £900 - £1,300 | £860 - £1,700 |
Alpha | £600 - £1,700 | £860 - £2,500 | £700 - £800 |

The UK, Welsh and Scottish Governments currently have several grants and schemes open to help homeowners upgrade their heating systems. Below is a list of those currently available:
Please keep in mind that grants and schemes are constantly changing, so it’s important to keep up to date if you wish to take advantage of these opportunities. We recommend checking your local Government websites to stay in the loop.
The average cost for boiler installation is usually between £1,500 - £3,000 but can reach costs of £5,000 based on the additional parts and labour that come with more complex installations.
Therefore, a like-for-like swap will cost considerably less than the average cost of a new boiler. That’s because installing a new boiler type means the pipework will have to be adjusted and any additional units, such as the hot water cylinder or cold water tank, will have to be installed/removed. You will also need to factor in labour costs and any day rates your installer might charge, particularly if the installation takes multiple days.
Additional costs might include:
Extra feature | Price range |
---|---|
System power flush | £50 - £150 |
Magnetic filter | £100 - £150 |
New boiler flue pipe | £50 - £150 |
Thermostatic heat controls | £70 - £650 |
Other factors that might add to the overall boiler installation cost include:
When it comes to boiler installation you need to look for an engineer with the right qualifications to handle your boiler type. For example, any gas boiler needs to be handled by a Gas Safe registered engineer, and an oil boiler requires an OFTEC technician.
These certifications ensure your installer knows exactly how to work with their respective fuels. While a plumber isn’t typically the first point of contact for boiler work, some plumbers may have these accreditations - so it’s worth checking this out when looking for quotes.
Independently researching the best, most trustworthy installer rates can be daunting. With GreenMatch’s nationwide network of licensed installers, you can be sure that there’s an installer nearby with quotes relative to your area.
Generally, the cost of installing a new boiler includes the combined costs of purchasing and fitting a boiler (i.e. price of labour and material). The labour cost for installing a new boiler will depend on factors such as the location, the complexity of the installation, and the number of engineers required. As it is well known, labour is one of the most expensive parts of most service work, so prices will increase if any additional work is required.
The average cost of a new boiler replacement will typically fall between £1,500 - £5,000.
This accounts for the cost of a new boiler, which typically falls between £500 - £3,500 and the average cost for installation, between £1,000 - £1,500.
At the lower end of this price range, installations will take comparatively less time and the boiler can be easily removed, with little revisions needed for pipework and fittings. These usually involve a like-for-like boiler swap.
If you’re looking for a biomass boiler, however, prices typically start from £4,000 and can reach upwards of £20,000.
The most expensive boiler replacement costs are for complex installations where the boiler is replaced by a new type and the existing boiler is not easily removed, with the pipework needing additional adjustment/replacements, or if the boiler is being moved to a new location.
Other ways to bring down the average new boiler cost and avoid overpaying come from comparing quotes from various installers. But how do you even go about finding qualified and available installers?
