What determines the costs of a central heating system?

The wide range of potential installation costs goes to show how unique every central heating installation project can be. The size of your home and the number of rooms it holds will help decide the scale of the job, from how many radiators you need, to your new boiler power output and the pipework distribution

Central heating cost factors

You will also need to account for the supply, installation, and labour costs involved. You should keep in mind that the installation costs will vary depending on the installer you hire. For instance, local installers will usually offer the cheapest rates, whereas opting for a national installer tends to be more expensive.

Average cost of installing central heating in the UK

Installing central heating in a 3-bedroom UK house typically costs £4,000 to £6,000. This price includes the boiler, radiators, pipework, and labour. However, the total cost can vary depending on factors like boiler type, property size, and existing pipework.

In general, the cost of installing central heating in the UK is between £2,000–£8,000. Here’s a break-down:

Central heating installation costs
Property sizeNumber of radiatorsEstimated cost
2-bedroom house/bungalow1–2£2,000– £2,600
3-bedroom house2–3£4,000–£6,000
4-bedroom house3–5£6,000–£8,000

It’s important to note that the cost can vary depending on the type of system installed, its size, and the requirements of the home. The cost of the boiler, radiators, heating controls, and pipework also contribute to the overall cost of your central heating system. 

The complexity of the installation process can also significantly influence the labour charges. It’s always a good idea to get a professional assessment before the installation so that you can receive a more accurate quote tailored to your home’s needs.

Combi boiler and radiator installation costs

Combi boiler and radiator installation costs vary depending on several factors but typically range from £1,700 to £5,500 in the UK.

Key factors affecting the cost include:

  • Property size: Installations for larger houses with more radiators generally cost more. A small 1-2 bedroom property may only need a 24-27kW combi, while a 4+ bedroom house usually requires a 35-42kW model.
  • Number of radiators: Adding new radiators increases installation complexity and price. An average 3-4 bedroom house has around 10 radiators, while a larger home may have 20 or more.
  • Boiler type & efficiency: High-efficiency combi boilers may cost more upfront but save on energy bills in the long run.
  • Fuel type: Gas boilers are most common, but oil or LPG options have different installation costs. Natural gas is the most common and affordable fuel for boilers.
  • Additional components: Smart thermostats, filters, or system upgrades can add £500–£1,500 to the final price. 

Average central heating system component costs

The average cost of central heating system components in the UK depends on several factors, including the type of system, home size, number of radiators, and any other necessary components. 

Components costs overview
ComponentAverage cost
Boiler£610–£3,837
Radiator (per unit)£40–£100

Heating control (thermostat)£100–£410
Pipework (per meter)£800–£1000

Finding the right boiler

A boiler is essential for a home’s central heating system, and choosing the right one depends on your home size and energy needs. Natural gas is the most popular fuel in the UK, with lower installation costs for homes connected to the gas grid. For those without gas, other options include LPG, oil, electric, or biomass boilers.

Combi Boiler Costs Per Fuel Type
Fuel TypePrice Range
Gas£600-£3,000
LPG£750-£2,700
Oil£1,200-£4,500
Biomass£4,000-£21,000
Electricity£500-£2,500

These figures exclude installation costs and are only estimates that might not apply to you. To find out the exact cost of a new combi boiler for your home, you will need to consult a heating engineer. We can help you get in touch with a professional in no time!

There’s no need to sacrifice your valuable free time researching and vetting heating experts on your own. GreenMatch can streamline the process for you.

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 ReplacementEstimated 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. 

However, looking for an installer requires hours of reading reviews and you most likely do not have that kind of time on your hands. To make things easy for you, we have done the research and found multiple reputable installers across the UK who can help you with your new central heating system.
