Costs of New Boilers: Types of Boilers

Before installation, new boilers cost between £500 and £3,000 on average. The type of boiler you choose will largely determine where your new boiler sits within this range. These price variations are summarised in the table below:

New boiler type Price range Average, inc. installation
Combi £500-£3,000 £2,750
System £580-£2,500 £2,790
Conventional £660-£2,750 £2,955
Electric £590-£2,500 £2,790
Biomass £4,000-£12,000 £16,000

Cost of a New Combi Boiler

New boiler type Price range Average, inc. installation
Combi £500-£3,000 £2,750

Since they only require one boiler unit to function, combi boilers are the most common type of boiler in the UK. Combi boilers are most suitable for small- to medium-sized homes with limited space because of their compact size.

Advantages of a modern combi boiler:

    • Hot water and heating comfort are available right away via the local mains network.
    • less heat is lost from the on-demand hot water system.
    • Since it runs off just a single unit, your home will have more space.
    • Compact size and low noise levels make installation simple practically anyplace in the house.

An issue with a combi boiler is:

    • cannot constantly supply large energy demands or simultaneously heat several outlets.

Cost to Replace a Regular Boiler with a Combination

A standard, also known as normal, boiler replacement can cost up to and even over £4,000.

If you want to increase system efficiency, this sort of replacement can be preferred because combi boilers can offer mains pressure water instantly for both heating and hot water.

On the other hand, traditional boiler systems contain a cold water tank that supplies water to a hot water cylinder and is typically placed in the loft. These extra appliances take up more room in your house and typically can’t produce as much flow as a modern combi boiler.

However, it’s crucial to keep in mind that this form of replacement necessitates additional parts and labour, as well as the removal of the cold water tank and hot water cylinder, in order to rearrange the pipework to make room for a new boiler type. The installation job will probably take an additional day to complete because of this, making the total time about two days.

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 installation’s intricacy will have a significant impact on the entire installation price. It is wise to get quotes from engineers in advance because of this.

Independently searching for heating engineers might be a tedious process. Up to 4 Gas Safe, or OFTEC, approved engineers can be found through GreenSavings Network, who can then provide bids based on the particular requirements of your property.

Cost of a system boiler

New boiler type Price range Average, inc. installation
System £580-£2,500 £2,790

System boilers maintain a steady supply of hot water storage from the local mains supply alongside a hot water cylinder. System boilers are thus appropriate for medium- to large-sized households with considerable energy requirements.

Advantages of a modern system boiler:

    • optimal heating and water pressure from the neighbourhood mains network.
    • Because there is no need for a cold water tank, it frees up room in the loft.
    • Multiple outlets can simply be heated at once by a hot water cylinder.

An issue with a system boiler is that

    • Sometimes the hot water cylinder needs to be reheated, which will delay the hot water flow.

Cost of a Conventional Boiler

New boiler type Price range Average, inc. installation
Conventional £660-£2,750 £2,955

The more conventional boiler types, such as conventional boilers, are generally found in older homes and structures. They will need the most room of any type of boiler because they need both a cold and hot water tank. As a result, medium to large homes are the greatest places to keep them.

Advantages of a brand-new traditional boiler:

    • is appropriate for medium- to large-sized homes since a hot water cylinder enables a continuous supply of hot water to several outlets.
    • Compared to installing a new boiler type, replacing an old boiler with a conventional one will result in lower installation expenses.

Negative aspects of a traditional boiler

    • Occupy a lot of room in the house
    • Low water pressure typically compared to mains pressure

The best manufacturers to choose for new boiler prices

 Manufacturers of boilers base the prices of their boiler lines on a variety of criteria, and there may be considerable variation between them. These include of the boiler’s extra features, the brand’s reputation, and the model’s general build quality.

The typical pricing ranges for each manufacturer, broken down by boiler type, are shown below:

Manufacturer Combi boiler price range System boiler price range Conventional boiler price range
Worcester Bosch £795-£2,865 £991-£2,515 £819-£2,402
Vaillant £910-£1,689 £888-£2,164 £854-£1,684
Viessmann £851-£1,453 £1,110-£1,382 £890-£1,453
Ideal £826-£1,394 £881-£1,329 £860-£1,692
Alpha £616-£1,698 £859-£2475 £704-£805
Baxi £659-£1,698 £828-£1,074 £731-£1,692

Costs of New Boilers for Different Boiler Models

The most expensive boiler types will have the biggest power outputs, making them ideal for large households with significant energy needs. These models will probably also include a number of extra features that increase their premium quality.

The table below divides new boiler costs into low-to-high price groups because there can be some variation in these expenses.

Boiler type Budget models Mid-range models Premium models
Combi £500-£900 £900-£2,100 £2,100-£3,000
System £580-£900 £900-£2,000 £2,000-£2,500
Conventional £660-£900 £900-£2,000 £2,000-£2,750

Cost of electric boiler

New boiler type Price range Average, inc. installation
Electric £590-£2,500 £2,790

Electricity can be used to power most boiler types, including combi and system boilers, as opposed to gas or oil. Due to this, electric boilers are a well-liked substitute for residences without access to the gas grid.

Although electric boilers don’t emit any carbon dioxide or other harmful gases while they operate, the majority of the electricity used to power them comes from burning natural gas. Despite this, electric boilers are typically regarded of as an environmentally beneficial boiler alternative. The high operating expenses of electric boilers are also partially attributable to the increasing price of natural gas.

By subscribing to a renewable energy supplier like Octopus Energy, you can stay away from this. Solar energy sources, such solar thermal and solar panels, are also available and can be used in conjunction with your electric heating system.

The UK’s shift to renewable, low-carbon heating is a priority for GreenSavings Network. The upfront expenses of these new technologies make them evidently unaffordable for many UK houses when they become available.

Therefore, until these new technologies become more economically feasible, moving to a new, energy-efficient boiler is the most cost-effective way to minimise your overall carbon footprint.

By placing you in direct contact with up to 4 qualified heating engineers, GreenSavings Network will spare you the hassle of seeking bids on your own. Due of this, comparing quotations is quick and simple. Our assistance is provided without expense or commitment.

What Financial Aid Is Offered by the UK Government for New Boilers?

In order to battle devasting energy price rises, boiler replacement and energy saving measures have become increasingly crucial. However, the expense of replacing a boiler has the potential to rise and become prohibitive for many.

In order to accelerate the transition to net zero by 2050, the government has established a number of incentives that assist in covering the costs of boiler repairs or new low-carbon heating systems.

The grants listed below are mostly subject to particular health- or income-related requirements.


    • Numerous incentives are available to finance new energy-efficient upgrades.
    • These include electric storage heating, loft/cavity wall insulation, air source heat pumps, and heating systems, including boilers.
    • Accessible all around the UK.

Boiler Improvement Plan

    • A reduction of £5,000 on the initial costs of an air source heat pump or biomass boiler.
    • Savings of £6,000 on a ground source heat pump’s price.
    • Only accessible to landowners in Wales and England.

Wales Warm Nest

    • Free advice on home energy efficiency upgrades.
    • These include installing solar panels, insulation, and new boilers and central heating systems.

Cost of installing a new boiler in the UK

The average cost of installation is typically between £650 and £2,500, but depending on the extra labour and parts needed for more complicated installations, costs can reach £4,000.

A like-for-like switch will therefore be much less expensive than installing a different boiler type. This is due to the fact that installing a new boiler type necessitates adjusting the pipework and installing or removing any auxiliary components, such as the hot water cylinder or cold water tank.

Additional expenses could consist of:

    • Power cleanse for system: £50-£150
    • £100-£150 for a magnetic filter
    • $50-$150 for a new boiler flue pipe.
    • Heat controls with a thermostat: £70 to £650

Additional elements that could raise the overall installation costs include:

    • shifting the boiler’s location within the house.
    • Your location and the cost of local installers.

It can be challenging to independently study the best, most reliable installer rates. You may be certain that there is an installation nearby with quotes specific to your area thanks to GreenSavings Network’s nationwide network of licenced installers.

Summary: The typical price of replacing a boiler

The normal price range for replacing a boiler is between £1,150 to £5,500.

This takes into account the price of a new boiler, which normally ranges from £500 to £3,000, as well as the standard installation fee of £650 to £2,500.

Installations at the lower end of this pricing range will go more quickly and the boiler can be removed with little modification to the pipes and fittings. These typically entail a boiler switch that is identical.

The most expensive boiler replacement costs apply to complicated installations where a new type of boiler is installed, the old boiler cannot be removed easily, pipework needs to be altered or changed, or the boiler is being relocated.

Standard installations will then cost between £650 and £2,500 to install. A more complex installation involving upgrading to a new boiler or relocating a boiler can cost upwards of £4,000+. This is because additional units need to be installed/removed and the plumbing needs to be readjusted.

Overall, the average replacement cost is between £1,150 and £5,500.

What is the price of a new boiler?

The cost of a new boiler (excluding installation costs) can range from £500 to £3,000. This depends on various factors including boiler type, fuel source, replacement type and boiler manufacturer.

How challenging is a combi boiler replacement?

The difficulty of replacing a universal boiler depends on the type of boiler you are replacing and the required upgrades to the fittings and surrounding plumbing. The ease of removal/installation of the boiler by a technician can also make the process difficult and time consuming.

Simple combination boiler replacement involves replacing the combination boiler with a combination boiler, as the replacement to a new type requires the installation of additional units, such as hot and/or cold water tanks.

Is purchasing a new combi boiler worthwhile?

Typically, combination boilers include the cheapest models on the market. A new combined boiler avoids heat loss from hot water storage as it supplies hot water from a network of pipes on demand. Combination boilers can also save relatively more house space because they are operated entirely by one device.
