The new boiler cost in the UK varies widely, spanning from £500 to £3,000, depending on the boiler type and manufacturer. This also depends on your household size, with 3 resident households being the most common in the UK. The best boiler for a 3 bed house will probably cost £1,100 to £2,000.

This installation cost encompasses the labour hours of the engineer and the intricacy of the installation process. Several factors, such as the boiler brand and your geographical location, can influence the final cost of installing a new boiler in your household.

Depending on the size of your property, you’ll need a specific boiler type. Thus, no matter how much you’d prefer a compact combi boiler for your 2000 sq ft house, it just won’t be able to heat it!

This means the bigger your property is, the higher your boiler investment will be.

Moreover, as the UK targets to reduce carbon emissions by 2050 within its Net Zero programme, boiler manufacturers are set to introduce a 20% hydrogen blend into the UK mains supply by that time. 

This way, boilers will run on a mixture of hydrogen and natural gas and gradually reduce carbon emissions from heating homes and buildings. Thus, most new boiler installations in the UK will be this type of boiler.

We surveyed over 5,000 homeowners in 2024 as part of our annual survey. 95% of the respondents were satisfied with their new installations.

Combi boilers, or combination boilers, are the most popular with UK homeowners. They are energy-efficient, providing both heating and hot water on demand without the need for a separate storage tank. A small combi boiler can be an ideal fit for a home with up to two bathrooms. Check out our dedicated page to help find the best combi boilers on the market today.

The average combi boiler cost is as follows:

System boilers are another favourite, known for their simplicity and ease of installation. They work with a separate hot water cylinder and suit larger households with higher hot water demands. If you're unsure which boiler is best for you, compare a combi boiler vs system boiler to get the right size for your needs.

The manufacturer, model, and fuel play a major role in choosing your system boiler. Yet, the size of your property, your home's energy needs, the efficiency rating, and the warranty length of your new boiler contribute to the system boiler cost, too.

A conventional boiler consists of a feed and expansion tank and a cold water cistern in the loft or attic. A hot water storage cylinder is required as well, usually stored in an airing cupboard. The total conventional boiler cost depends on the:

Electric boilers are perfect for smaller-sized homes that have less demand for hot water and limited storage space. 

Electric boiler costs can range from £590 and £2,500 but the running costs, however, are higher as electricity is more expensive than gas. This can lead to higher running costs and energy bills.

It’s possible to find combi, conventional and system boilers that run on electricity instead of gas or oil. This feature makes electric boilers a favoured choice for homes that are not connected to the gas grid. Furthermore, the top-performing electric boilers boast efficiency ratings nearing 100%, allowing you to maximise your energy usage.

This is why electric boilers are commonly considered an environmentally friendly boiler option provided the electricity fueling the boiler comes from renewable resources. They operate without emitting carbon emissions or harmful gases.

Electric heating may potentially become the only game in town when it comes to newly-built homes. The gas boiler ban for new homes aims to phase them out in favour of electricity after 2025 (although this may be subject to change). Read our page about heat pumps vs gas boilers to learn more.

The new boiler installation cost in the UK generally falls within the bracket of £1,500 to £2,955. The variability primarily stems from factors like boiler type, complexity of installation, additional materials, or the brand you choose. 

This cost also includes the labour hours of the engineer and factors in the complexity of the installation.

When installing a new boiler, your project may involve the removal of old units and the addition of new components. This is especially likely during conventional or back boiler replacements, which include the most components. Additional expenditures to consider may include:

Also, the installation price can be affected by the rates of a particular installer or a location where you prefer to see your new boiler.

Local installers can provide the best boiler deals. However, independent searches of trusted installers can take hours if not days. Moreover, that’s not a bulletproof way to find a certified company with the proper expertise for the best price.

Homeowners and tenants looking to enhance the energy efficiency of their homes and save on costs have the opportunity to benefit from various boiler grants. 

The Energy Company Obligation (ECO) scheme, designed to promote energy efficiency, offers grants to help households cut their central heating expenses and boost their home's energy efficiency.

You can apply for this new boiler grant under the ECO4 scheme. It's worth noting that this scheme will run up until 31 March 2026.

In Northern Ireland, the Boiler Replacement Scheme was exclusively applicable to homeowners or tenants with boilers that were at least 15 years old and operating inefficiently. This scheme closed in September 2023.

Consider consulting an experienced boiler installer to find out whether you qualify for any grants.

Opting for a new boiler installation can result in enhanced efficiency, reduced energy expenses, and an increased level of comfort in your home. 

After you have the new boiler and installation cost settled, you might wonder when your investment will break even. In a similar fashion to the boiler running costs, your savings will largely depend on the boiler itself, your energy consumption habits, and current energy prices.

This way, how much you save with a new boiler depends on its efficiency, your electricity usage, and energy prices. A Gas Safe registered engineer can estimate the payback period by looking into your particular boiler type, electricity consumption, and housing situation.
