How Much Does It Cost To Install Central Heating?

How Much Does It Cost To Install Central Heating?

Installing a new central heating system is a major home improvement project that can significantly increase your home’s value and comfort levels. However, it also comes with a hefty price tag. 

In the UK, the average cost to install central heating ranges from £3,000 to £4,500 for a typical three-bedroom home.The exact cost will depend on several factors, including the type of heating system you choose, the size of your home, the complexity of the installation, and whether you need to replace any existing pipework or radiators.

Types of Central Heating Systems and Their Costs

The most common types of central heating systems in the UK are: 

Gas Boiler Systems

  • Combi boiler: £1,500 – £3,500 for supply and installation
  • System boiler: £2,000 – £3,500 for supply and installation
  • Regular/conventional boiler: £2,500 – £4,000 for supply and installation

Gas boilers are generally the most affordable option, with combi boilers being the cheapest to install.

Electric Heating Systems

  • Electric boiler: £1,000 – £3,000 for supply and installation
  • Storage heaters: £1,500 – £4,000 for supply and installation

Electric systems tend to be more expensive to run than gas, but can be a good option if your home is not connected to the gas network.

Renewable Heating Systems

  • Air source heat pump: £8,500 – £12,000 for supply and installation
  • Ground source heat pump: £18,000+ for supply and installation

Renewable systems like heat pumps have higher upfront costs but can save money on energy bills in the long run and are more environmentally friendly.

Additional Costs

Beyond the heating system itself, you may need to factor in costs for:

  • Pipework installation: £500 – £1,500
  • Radiator installation: £100 – £300 per radiator
  • Chemical flush of existing pipework: £300 – £500
  • Building works like lifting floors: £500 – £1,500

For an average three-bedroom home needing a full central heating installation with 8-10 radiators, the total cost could range from £4,000 to £8,000 or more depending on the system chosen.While the upfront cost is significant, installing an efficient modern central heating system can save money on energy bills over time and add considerable value to your property.

How a central heating system could save you money


Installing a new, efficient central heating system can save you money in a few ways:

Lower Energy Bills: Modern condensing boilers are way more efficient than older ones. They turn over 90% of the fuel into heat, compared to just 60-70% for older boilers. This means you spend less on gas or electricity to heat your home.

Cheaper to Run: New boilers work at lower temperatures, so they don’t need to run as often to keep your home warm. Plus, things like programmable thermostats and thermostatic radiator valves help cut down on wasted energy.

Fewer Repairs: Getting rid of an old boiler means you won’t have to deal with breakdowns and expensive repairs. New boilers come with longer warranties, often 5-10 years, giving you extra peace of mind.

Increased Home Value: A modern, efficient heating system makes your home more appealing and valuable to potential buyers.

Lower Environmental Impact: High-efficiency boilers produce fewer carbon emissions, which is better for the environment.

How much you save depends on your home’s size, how well it’s insulated, your old system’s efficiency, and current energy prices. But you could realistically save around £200-£300 a year by upgrading to a new A-rated boiler and heating controls. The initial cost is worth it because you’ll get that money back over a few years through these savings.

Save money on your central heating installation with the ECO scheme

The ECO (Energy Company Obligation) scheme is a great way for people with low incomes or those struggling with high fuel costs to get help installing a brand-new central heating system without spending a lot. From April 2022 until March 2026, during the ECO4 phase, there are grants available that fully cover the costs of a new gas condensing boiler, radiators, pipes, and even a gas connection if you need one.

To be eligible, your home should not already have a central heating system. You need to be a homeowner or have your landlord’s permission if you’re renting. You also need to be getting certain means-tested benefits or qualify under ECO Flex rules from your local council.

Approved installers will check out your home to see how energy-efficient it is and decide what kind of heating system and insulation you need. The goal is to make your home more energy-efficient, lower your heating bills, and cut down your carbon footprint.

Warma UK is there to help you figure out if you qualify and to guide you through applying for cental heating grants. They make the process easier and can answer any questions you have about getting started.
