Drawing from our experience, the average new boiler costs range from £500-£4,000 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 of any new boiler also includes the installation price, although this can vary from installer to installer. This is one of the many reasons you should find an engineer you can trust, which can take days of research if undertaken on your own. Luckily, we can help speed up the process and spare you the headache of fielding professionals and gathering prices alone.

New combi boiler cost
| New boiler type | Price range | Average, inc. installation |
|---|---|---|
| Combi | £500-£3,000 | £2,750 |
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.
- Instant supply of hot water and heating comfort from the local mains network.
- Reduced heat loss from on-demand hot water.
- Save space in your home since it operates from one unit.
- Combi boiler installation is characterised by low noise and compact dimensions which result in an easy installation almost anywhere in the home.
- Cannot always meet high energy demands, or provide hot water multiple outlets at once.
Cost of replacing a conventional boiler with a combi
Replacing a conventional, aka regular, boiler with a combi will typically cost up to and beyond £4,000.
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-£3,000 |
| Average total replacement cost | £4,000 |
The complexity of the installation will have considerable bearings on the overall installation costs. That’s why it’s a good idea to receive quotes from engineers beforehand.
Looking for heating engineers independently can be a painstaking, time-consuming, and stressful task. Fortunately, we are on hand to connect you with up to 3 Gas Safe, or OFTEC, approved engineers who will offer quotes based on your home’s unique specifications. Start by simply filling in the form and you’ll soon be on your way to upgrading your home!

Electric boiler cost
| New boiler type | Price range | Average, inc. installation |
|---|---|---|
| Electric | £590-£3,000 | £2,790 |
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 boilersare 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 electric boilers and electric combi boilers.
You can avoid this by signing up with a renewable energy provider, such as Octopus Energy. 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.
Benefits of a new electric boiler
- Smaller, easy to install, and can be an attractive option for households off of the gas grid since they do not require connection to the gas line.
- Efficiency ratings close to 100%.
- More environmentally friendly since they are not powered by fossil fuels.
Disadvantages of an electric boiler
- The tendency to be more expensive than gas boilers, since electricity is pricier than gas.
- Can have problems meeting hot water and heating demand for larger households.
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.
System boiler cost
| New boiler type | Price range | Average, inc. installation |
|---|---|---|
| System | £580-£3,500 | £2,790 |
System boilers, alongside a hot water cylinder, keep a constant supply of hot water storage provided by the local mains supply. This makes system boilers suitable for medium-to-large homes with high energy demands.
- Optimal water pressure and heating comfort from the local mains network.
- Saves space in the loft as there’s no need for a cold water tank.
- Hot water cylinder can easily supply hot water to multiple outlets at once.
- The hot water cylinder will occasionally need to reheat which will cause a delay in the hot water supply.
Conventional boiler cost
| New boiler type | Price range | Average, inc. installation |
|---|---|---|
| Conventional | £600-£3,500 | £2,955 |
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 they require a hot water cylinder and a cold water tank. Therefore, they are best kept in medium-to-large homes.
- Suitable for medium-to-large homes as hot water cylinders allow for a constant supply of hot water to multiple outlets.
- A conventional boiler replacement will reduce installation costs compared to installing a new boiler type
- Take up a lot of space in the home
- Typically low water pressure compared to mains pressure

What grants does the UK Government provide for new boilers?
Boiler replacement and energy efficiency measures have become especially important in recent years to combat devastating energy price spikes. However, the average cost of a new boiler replacement has the potential to mount and become unaffordable to many.
Our team found that the government has released various grants to help cover the costs of boiler replacements or new low-carbon heating upgrades, designed to push the transition to net zero by 2050.
Eligibility for the grants outlined below is mostly subject to certain income or health-related criteria.
- Range of grants to fund new energy-efficient improvements.
- These include heating systems (including boilers), loft/cavity-wall insulation, air source heat pumps, and electric storage heating.
- Available across the UK.
- £5,000 off the upfront biomass boiler cost of a biomass boiler, or air source heat pump (ASHP).
- £6,000 off the costs of a ground source heat pump.
- Only available for property owners in England and Wales.
- Free consultations and home energy improvements.
- These include boiler/central heating replacement, insulation, and solar panels.
- Extends to private sector tenants, as well as homeowners.

- Extends to private sector tenants, as well as homeowners.
Boiler Replacement Scheme, Northern Ireland
- £400, £500, or £1,000 off the upfront costs of a new boiler replacement in Northern Ireland.
- The amount depends on the household’s gross annual income.
New boiler installation cost in the UK
The average cost for installation is usually between £650-£2,500 but can reach costs of £4,000 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.
Additional costs might include:
- 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 installation costs include:
- Relocating the boiler to a new position in the home.
- Where you live and local installer rates.
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.
Are labour costs included in boiler costs?
In the event of purchasing a new boiler, among the questions that are often considered are those relating to whether the labour costs are included or not in the total cost of installing a new boiler.
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.
Summary: average cost of boiler replacement
The average cost of a new boiler replacement will typically fall between £1,150-£5,500.
This accounts for the cost of a new boiler, which typically falls between £500-£3,000 and the average cost for installation, between £650-£2,500.
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.
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 come from comparing quotes from various installers.
