How Much Does It Cost To Install A Central Heating System In The UK?

Looking for a reliable central heating system at an affordable price in the UK? Here are some average costs of heating systems including oil & electric units

The price of central heating systems will vary depending on a number of factors such as the type of property and other essential components. When choosing a new central heating system, make sure you factor in a budget between £3000 to £4000. The cost may vary depending on the fuel type, boiler location, number of radiators, as well as the characteristics of your property.

That being said, you need to make sure that you compare the heating system prices you feel will be ideal for your needs. Additionally, you want to make sure that you deal with a reputable, accredited company for the installation. Otherwise, you’ll be left with a bigger bill on your hands if and when problems crop up in the future.

In this post, we’re going to look at some of the average costs of central heating system installation to help you budget and make an informed decision.

Choosing the right type of boiler for your home and lifestyle is essential. However, you also need to consider the suitable fuel type as this will help you choose the ideal system and estimate of costs involved.

In the UK, the most common fuel used for a boiler is natural gas, with about 80% of homes opting for gas boilers. Natural gas can be delivered to your property from energy suppliers, but this is only available for homes connected to the gas network.

Not connected to a gas network? The alternative would then be oil and liquefied petroleum gas (LPG), which can be stored on your property. However, because a storage tank will need to be installed on your property, you will need ample outdoor space for the tank.

You will also need to consider that the efficiency of these fuels or heating is also fossil fuels. This means that they emit greenhouse gases which have a major impact on climate change. The alternative to this could be a more sustainable solution such as biomass boilers that burn organic materials. These central heating systems are more expensive than gas and oil. 

On the other hand, electric boilers are particularly great for small homes and flats with less than ten radiators with a single bathroom. These systems are a simple form of heating because they use electricity to produce central heating and hot water without burning any fuels.

Three Types Of Boilers:


Also known as a combination boiler, these boilers collect water directly from the mains without the need for a hot water cylinder. Combi boilers are a good choice for smaller homes with limited space as the water is only heated on demand for both heating and domestic use.


Here we have the system boiler, which collects water from the mains without needing a feed tank in the attic. It also needs a hot water cylinder to hot water stored for tap usage and heats the water from the water supply for your radiators. Make sure you have space for the cylinder tank on your property.

Conventional Or Traditional

A regular or conventional heating system comes with a boiler, hot water storage cylinder, and a feed expansion tank that can be placed in the attic. These systems need gravity to feed water downwards from the tank where the boiler heats it. The boiler heats the water supplied to the radiators, and the hot water for your homes’ taps is stored in the storage cylinder. One thing you need to remember is that this alternative relies on gravity, which means that the water flow may not always be great. So, if you hardly use or do not need much hot water, this is a great option for you.

Boiler Type Average Cost (Excluding Installation):

Combi   £500 – £2,000

System £500 – £2,500

Regular £500 – £2,750

Remember, there’s a lot to factor in when you want the overall price of central heating systems; boiler makes, boiler size, heating controls, pipework and radiators, installations and the complexities involved, as well as labour costs.
