As the cost of living rises, more people are looking to install a new boiler to save on their energy bills. What is the average cost of a new boiler installation? How can you make sure you’re getting the best deal?

It may be on its last legs if your boiler is over a decade old. Older boilers are less efficient and more likely to break down. Many homeowners opt to replace their boilers every 10-15 years. But if you’re wondering how much a boiler installation costs, you’re not alone.

New boiler costs can vary depending on several factors; the final price will also depend on whether you need to install additional piping or make other modifications to your home. But once you’ve factored in all the costs, you can enjoy peace of mind knowing that your new boiler will keep your home warm and comfortable for years to come.

Read on for information about the cost of boiler installations in the UK.

What are the most common cost factors when installing a boiler?


Fuel source

The most common types of boilers are gas, oil, and electric. Gas boilers are the most
expensive, followed by oil and electric, and gas boiler requires particular installation and
ventilation requirements. Oil boilers also require unique installation, but not to the same extent as gas boilers. Electric boilers are the least expensive to install but have the highest operating costs, and all because electric boilers require a lot of electricity to use.

Relocation/ Size

Suppose the boiler is situated in a difficult-to-reach spot. In that case, it may cost more to install due to its complexity than a boiler located in an easily accessible area.

For example, when relocating your boiler from the bathroom, you should always leave it to a professional. Hiring a certified gas engineer and experienced bathroom expert will ensure that your boiler is moved with safety and efficiency in mind. Not only that, but these experts are also familiar with local regulations and building codes to prevent any unnecessary delays or problems during the process. With their help, you can be sure that your boiler will be moved safely and properly to provide optimal performance once it is relocated.

In addition, the size and type of boiler can also affect installation costs.

A larger boiler, for example, may require more materials and labour to install than a smaller model. The best way to get an accurate installation cost estimate is to consult a licensed contractor who is familiar with the specific requirements of your project and who can give you a calculated total.

Additional Work

Several add-ons, such as a power flue or condensate pump, can increase the new boiler cost installation price since additional parts and more labour are involved. For example, If your home doesn’t have a gas line, you’ll also need to pay for a gas meter and supply pipe, or if you have an older home, you may need to install new pipes or make other modifications to accommodate the new boiler. All these little parts will bring up the total cost of your installation.

Considering everything, you can generally expect to pay between £2000 and £4,000 for a boiler installation in Scotland… The average cost is £3,200; the total price includes the boiler price, labour and materials



What type of boilers can you get installed?


Three central boilers are used in homes today – combi boilers, system boilers, regular boilers and last but not least electric boilers. Each type has pros and cons, so choosing the right one for your home and needs is essential.

Combi boiler

A new combi boiler provides both heating and hot water directly from the boiler. Meaning there is no need for a separate hot water cylinder or cold water tank, making it a more efficient space-saving option. A combi boiler installation is also very versatile, as you can use it with traditional radiator systems and underfloor heating. In addition, they are relatively easy to install, as they don’t require additional pumps or tanks.


However, a downside of combi boilers is that they tend to be less powerful than other types of boilers, so they may not be suitable for larger homes or homes with multiple bathrooms, unlike system boilers.

System boiler


Next, we have a system boiler which is an excellent option for larger homes with multiple bathrooms, as it provides high levels of hot water without needing a separate cylinder.


System boilers also tend to be more efficient than traditional boilers, as they store hot water in a header tank, meaning it doesn’t need to be reheated each time you turn on the tap. A downside of system boilers is that they require regular maintenance to keep them running smoothly.

Regular boiler

A boiler commonly used is a regular boiler, a traditional heating system that uses a hot water tank and is usually located in an airing cupboard. The water is heated using a gas-fired boiler.


This system is often used in properties with two or more bathrooms, providing a constant hot water supply. Regular boilers are relatively simple to install, as the hot water tank doesn’t need to be located in the same spot as the boiler. Unfortunately, the hot water tank can take up quite a bit of space which isn’t ideal for smaller homes.


Electric boiler

Finally, electric boilers are an excellent option for many homeowners because it is highly efficient and easy to use. Electric boilers use electricity to heat water, circulating through radiators or underfloor heating systems. Because they don’t require a gas connection, they are effortless to install and are often much cheaper to run than other boilers.


Additionally, electric boilers are very Low Carbon Emitting (LCEM), which means they are kinder to the environment. One downside of electric boilers is that they can take longer to heat up than gas boilers, which is offset by the fact that they are usually more energy-efficient in the long run.



How to know when you need a new boiler installed

While some people may think they can get by with an old boiler, the truth is that a new boiler can be a huge asset. Not only will it be more energy-efficient, but it will also perform so much better. Here are a few signs that it might be time to replace your boiler:

  • Your energy bills are increasing: If your energy bills have been steadily growing, it could be because your boiler is no longer as efficient as it once was. A new boiler will help you save money on your energy bills.
  • Your boiler is making strange noises: If it is banging, whistling, or hissing, it could be a sign that something is wrong. A new boiler will run more quietly.
  • You’re not getting enough hot water: If you’re not getting enough hot water from your shower or taps, it could mean your boiler isn’t working as efficiently as it should be. A new boiler will provide you with all the hot water you need.
  • If your boiler is around 10-15 years old, it might be coming to the end of its lifespan. Boilers of this age become less energy efficient and cause a spike in heating costs due to poor performance and high chances of breaking down.


While the initial cost of installing a boiler may seem high, it is essential to remember that boilers are a long-term investment and picking the right one for your home will save you money in the long run. The right boiler can last for decades with proper care and maintenance, providing your home with reliable heat for the years to come. Considering the costs and benefits of boiler installation, it is clear that this is a wise investment for any homeowner.
