Type of boiler replacement

The central heating replacement cost will be directly impacted by the kind of boiler replacement you need. For instance, a like-for-like boiler swap in the same position in your home will be easier than changing the position of the boiler or changing the type of boiler. 

A like-for-like swap means that the surrounding pipework can connect easily to the new boiler, which can usually be done in about a day or two. On the other hand, switching to a new type of boiler could take a few days, since different boiler types require different components which will need to be installed or taken away. 

Boiler replacement costs
Type of Boiler Replacement Estimated Cost
Like-for-like combi boiler swap  £1,700-£3,500
Replacing a system boiler with a combi boiler £1,500-£3,000
Replacing a conventional boiler with a combi boiler £2,500-£4,500

If we assume a home is installing a new combi boiler, the UK’s most popular boiler type, then the boiler replacement costs will depend on the old boiler type.

Type of boiler: combi, system, conventional

boiler types

Central heating system price varies depending on the type of boiler you choose for your household. 

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.

New combi boiler prices range from £600-£3,000. Combi boilers can be fuelled by gas, oil, LPG or electricity.

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.

System boilers cost somewhere between £600 and £3,800. Including installation, the average cost of a like-for-like boiler swap is around £1,900. 

Conventional boilers come with a hot water cylinder and a cold water storage tank. They are an excellent choice for homes with low water pressure, as they can supply substantial amounts of hot water to multiple bathrooms.

Conventional boilers, also known as regular boilers, cost somewhere between £650-£3,200. Regular boilers require a cold water tank which is kept in the loft of a home. 

All of these boilers can work with different fuels, which will have further implications for your expenses. For instance, electric central heating installation cost will differ from oil or biomass systems. Moreover, don’t forget about factoring in how much replacing central heating pipes cost and investing in other crucial components, like radiators and thermostats.

For the most tailored prices, you will want to consult a heating engineer who can assist you in finding the right options for your home.

Type of fuel: gas, oil, electricity, LPG, biomass

boiler fuel types

First and foremost, let’s agree on what we mean by boiler fuel type. The most common sources of heat in boilers are gas, oil, electricity, LPG, and biomass.

However, gas-fired boilers burn natural gas or liquefied petroleum gas (LPG) as a fossil fuel to generate heat. At the same time, electricity doesn’t burn, so it can’t be considered a fuel, but rather a source of heat. Therefore, we’ll discuss types of boiler fuels as sources of heat

In the UK, natural gas is the most common and popular fuel for boilers, delivered through the gas network, and the cost of gas central heating depends on current gas prices. While gas is a convenient and widely used energy source, it’s important to note that its combustion releases carbon dioxide into the atmosphere, contributing to greenhouse gas emissions and climate change.

However, not all properties have access to the gas network. Alternative fuels, such as oil and LPG heating (liquefied petroleum gas), can be stored on-site. While effective for heating, these energy sources are also fossil fuels that emit greenhouse gases when burned. Fortunately, a ‘greener’ alternative exists in the form of biomass.

Biomass boilers burn organic materials and offer a more environmentally friendly option. For smaller homes, electric boilers provide a straightforward choice, operating without burning fuel and utilizing electricity for heating and hot water production.

Electric boilers are very efficient since they don’t burn fuel to produce heat. If paired with the green electricity grid, electricity-powered central heating systems can also be better for the environment, especially when combined with a domestic solar PV system. Remember to consult a professional installer to find out the gas, oil, LPG, biomass or electricity central heating installation cost.

Fuel type cost overview
Fuel type Boiler price Running cost (per year)
Gas £600–£3,500 £91
Oil £1,000–£4,500 £500–£600
LPG £1,000–£3,500 £500–£600
Electric £900–£3,500 £500–£1,500
Biomass £4,000–£21,000 £500–£1,500

Hot water cylinders: vented and unvented hot water cylinders

Hot water cylinders are storage tanks that hold cold water for central heating systems. Vented and unvented hot water cylinders are a popular choice as they are simpler and more basic in design.

Unvented vs Vented System

Installing a brand new sizzling water cylinder will price significantly greater than a like-for-like substitute in the identical location because the surrounding pipework should be fitted to include it into the bigger heating system. 

Hot water cylinders price
Hot water cylinder sort Estimated price (incl. set up)
Vented sizzling water cylinders £400-£900
Unvented sizzling water cylinders £400-£1,300

Installation prices may also depend upon the kind of cylinder, in addition to the fabric it’s comprised of. Copper cylinders are extremely efficient warmth conductors and have a tendency to price lower than chrome steel cylinders, however they gained’t final as lengthy. A sizzling water cylinder that immediately heats the water with inner immersion heaters will usually price greater than an oblique system the place the boiler heats the water.  

Vented sizzling water cylinders

A vented sizzling water cylinder is a part of a traditional boiler system, costing £400–£900. Connected to a loft-based chilly water storage tank, set up is usually cheaper than unvented cylinders. 

However, putting in a brand new standard boiler requires an extra £200–£450 for a chilly water tank. Note that compatibility points with current pipework could come up as a result of larger water strain, however including a water pump can improve strain with out requiring a full system substitute.

Unvented sizzling water cylinders

An unvented sizzling water cylinder is pricier, starting from £400–£1,300. It attracts chilly water immediately from the mains by way of an enlargement vessel and will be paired with a system boiler for high-pressure sizzling water distribution. 

With no want for a chilly water cistern, set up flexibility will increase, and the method is easier. However, altering the cylinder’s place requires pipework changes, so sustaining the identical location is advisable throughout replacements.

Here’s a fast comparability of vented and unvented water cylinders:

Hot water cylinders overview
Feature Vented sizzling water cylinder Unvented sizzling water cylinder
Water supply Cold water tank (gravity-fed) Mains water (direct connection)
Pressure Weaker strain Stronger strain
Required area Cold water tank within the loft No chilly water tank required
Boiler compatibility System or standard Combi or system
Estimated price (set up included) £400–£900; further £200–£450 for chilly water tank £400–£1,300


Radiators typically final 15-20 years. Upgrading your central heating system with a brand new boiler could not at all times require new radiators until your present radiators present indicators of serious rust or there are leaks or inefficient warmth distribution. 

Older radiators could accumulate sludge, affecting water move and warmth high quality; a system flush can tackle this problem earlier than contemplating substitute.

If substitute is unavoidable, commonplace radiators usually price between £20-£250 every, whereas designer-style radiators could attain as much as £800. Installation prices range, starting from £150-£750 for normal radiators and roughly £900 for designer kinds. 

Upgrading an current radiator typically takes 2-3 hours for smaller models and 4-5 hours for bigger ones.

Factors comparable to changing with the identical sort or a combi boiler and radiator set up price can affect the entire worth. 

The desk beneath outlines the value ranges for every sort of radiator set up:

Radiator set up costs
Type of radiator substitute Price Range
Fitting a brand new radiator  £170-£1,000
Replacing a radiator with the identical radiator sort  £150-£450
Replacing a radiator with a brand new radiator sort £250-£680

If you’re becoming new radiators, you could purchase the correct amount of radiators to warmth your house. Too many radiators will produce pointless extra warmth which wastes power that you’ll have to pay for. On the opposite hand, too few radiators will not present sufficient warmth to sufficiently heat up the area.

Generally, every room requires 1 radiator. However, bigger rooms would require extra warmth so they may want 2 or perhaps 3 small radiators. Larger radiators usually have the next energy output as a result of their bigger floor space. Therefore, these may also price extra.

A heating engineer can estimate the required measurement and energy output for a radiator by calculating the British Thermal Units (BTU) of a room. A room’s BTU will be affected by its measurement and the standard of your house’s insulation.

Also, in your comfort, a heating engineer also can calculate how a lot the present new boiler and radiators price within the UK or, for instance, a combi boiler and radiator set up price.
