Replacing an old boiler is not only important for efficiency and reliability but could also end up saving you money in the long run.

The cost of a new boiler can vary significantly depending on several factors including the type of boiler, the model and where you are located in the country.

Our guide below helps to explain why you should look at replacing your current boiler and help explain the types of boiler you may encounter in your search.

Why is it Important to Replace Your Boiler?

There are a number of reasons you should consider replacing your boiler including:


In the UK, where energy costs are high, having an efficient boiler is crucial. Older boilers tend to be less energy-efficient, resulting in increased heating bills.

Upgrading to a new, high-efficiency boiler can lead to substantial cost savings over time, as well as a reduced carbon footprint. Modern boilers comply with the latest energy efficiency regulations, ensuring optimal performance and savings.


The UK experiences cold winters, and a breakdown in the heating system can be inconvenient and uncomfortable. Older boilers are more prone to failures, leaving homeowners without heating and hot water.

By replacing an aging boiler, you can improve the reliability of your heating system, reducing the risk of unexpected breakdowns and ensuring uninterrupted comfort during the colder months.


It is possible that older boiler models may not meet the necessary safety standards, increasing the risk of carbon monoxide leaks or faulty controls.

Investing in a new boiler ensures compliance with safety regulations and provides the latest safety features, such as carbon monoxide detectors and improved controls, guaranteeing the well-being of your household.



What are the Different Types of Boilers Available in the UK?

  • Combi Boilers Combi boilers are the most popular choice in the UK. They provide both central heating and hot water on demand, without the need for additional tanks or cylinders. Combi boilers are space-efficient, making them suitable for smaller properties. They offer fast hot water delivery and are energy-efficient.

  • System Boilers – System boilers work with a separate hot water cylinder, but like combi boilers, they don’t require a cold water tank. They are ideal for properties with multiple bathrooms, providing hot water to several outlets simultaneously. System boilers offer efficient water pressure and can be an excellent choice for medium to large households. They are also compatible with solar water heating systems.

  • Conventional Boilers – Conventional boilers, also known as regular or heat-only boilers, are commonly found in older UK properties. They require both a cold water tank and a hot water cylinder. Conventional boilers can provide hot water to multiple outlets simultaneously and are suitable for larger households with high hot water demands. However, they occupy more space and may be less energy-efficient compared to combi and system boilers.

  • Electric Boilers Electric boilers are an alternative for properties without access to a gas supply. They are compact, silent, and offer excellent energy efficiency. Electric boilers are easier to install and require less maintenance. They can be more expensive to run compared to gas boilers due to higher electricity costs.

Considering The Cost

The cost of a new boiler installation in the UK depends on various factors, including the type and size of the boiler, the complexity of the installation and any additional work required, such as upgrading the pipework or radiators.

The brand and model of the boiler, as well as regional variations in material costs, can also impact the overall price.

On average, a new boiler installation in the UK can range from £2,000 to £4,500 or more. It is advisable to obtain multiple quotes from reputable heating engineers to ensure you receive the best value for your investment.

Understanding the different types of boilers available helps homeowners choose the most suitable option for their specific needs.

While the cost of a new boiler installation can seem significant, the long-term benefits in terms of energy savings and improved performance make it a worthwhile investment.
