How much does a New Boiler Cost?
The average cost of a new boiler installation typically ranges from £1,000 to £3,500 in the UK. There are a number of factors that can influence boiler installation prices, as we will explore below.
Boiler Size: Larger homes, with more radiators and bathrooms, will require a larger boiler compared with smaller homes. These larger boilers have a higher output and power rating, and cost more than smaller boilers of a similar specification.
Boiler Brand: The cost of a new boiler can vary between boiler brands, with brands such as Worcester-Bosch costing as much as 60% more than the price of cheaper brands, such as Glow Worm.
Fuel Type: There are a number of different fuel sources boilers can use for your heating and hot water. Gas boilers are generally the cheapest, followed by oil and LPG boilers. Biomass and electric boiler units are more expensive.
Boiler Type: Conventional boilers are often the cheapest to install and replace, followed by combi boilers. System and condensing boilers are slightly more expensive, with each different type having it’s own pros and cons.
Replacement or New Install: Replacing a boiler with the same type and fuel source will normally be much cheaper than changing to a different fuel or different type of boiler (such as changing from a system boiler to a combi).
There are also other factors that can influence the price of a new boiler, such as your location in the UK. Prices are often higher in London and the South of England compared with the rest of the UK. The availability of local boiler engineers can also influence pricing, as remote locations may be charged extra travel costs for the boiler technicians to carry out the work.

Installing a new boiler
Below is a guide to boiler replacement, including some considerations that may influence the type of boiler you choose for your home.
Why are you replacing your current boiler?
There are many reasons you may be wanting to replace your old boiler. The most common reasons are that the current boiler is broken or quite old. Boiler replacements are also common when a homeowner wants a more economical boiler, or as part of a house renovation.
What type of fuel do you require?
It isn’t uncommon to change the fuel type when installing a new boiler. Certain fuel sources, such as electricity, can be more economical and better for the environment, so are becoming increasingly popular. In some homes, not all fuel sources are available – for example, not every property in the UK has access to a gas line, so would not be able to install a gas boiler.
If changing the fuel type of your boiler, ensure your chosen engineer is qualified to carry out the work. For example, any gas related work must be carried out by a Gas Safe engineer.
What size boiler do you need?
The number of bedrooms and bathrooms in your property will likely determine the boiler size you will need. Larger homes with more bathrooms will need a bigger boiler to provide sufficient hot water to all of the taps. Similarly, a home with more bedrooms will need a larger boiler to handle the heating.
If you have any questions about what size boiler you require, get in touch.
What type of boiler do you want?
The most common types of boiler are combi, system and regular/conventional boilers. Combi boilers have become the primary choice for most homes, as they require minimal space and deliver hot water and heating on demand.
Larger homes with space to install the alternative boiler types may benefit from a larger on-demand hot water capacity. You can find out more about the different types of boilers here, or feel free to contact our boiler engineers for more guidance.
Where will the boiler be located?
Boilers can be located in a range of different locations throughout the home. Commonly, they are found in the kitchen, a utility room, loft or an airing cupboard. However, you can also place them in other locations that are convenient for you, such as a garage.
If you are replacing your current boiler, it will be cheaper to install the new unit in the same location rather than moving it to a new location.
How do you plan to pay for your boiler install?
Whilst most homeowners choose to pay for boiler installations in full, there are a growing number who prefer to spread the cost with finance. Finance is a great way to have your boiler upgraded now and pay it off over the coming years, but homeowners should consider any interest that may be payable.
Like any loan, boiler finance is subject to status and checks. If you are interested in financing a boiler replacement, get in touch.
Types of Boiler
The type of boiler you have may influence the boiler professional you choose. Certain types of boiler require specialist training and certification. For example, a gas boiler replacement must be carried out by a gas safe registered engineer. Your home’s boiler type can also influence replacement prices, due to the varying degrees of difficulty.
Combi Boilers are the most popular choice for UK households. New combi boilers are not only compact, but also highly efficient and reliable.
Combi Boilers can run on most fuel types, including gas, electricity and oil, however, if you are trying to keep installation costs low it is recommended to stick with same fuel type for your replacement boiler. For example, If your current boiler runs on gas, installing a new gas boiler will typically be cheaper than switching to either electricity or oil.
