In the UK, the average cost of a new boiler central heating system typically ranges between £3,000 and £7,000. However, this cost can vary depending on several factors, including the type of boiler, manufacturer, size of the heating system, regional labour costs and the complexity of the work involved.

Installing a new boiler or central heating system is therefore a significant investment for any homeowner, and understanding the costs involved is crucial for budgeting and planning. 

Warmable has put together the following guide to include the factors that will impact the cost of new central heating system installation.


What Factors Affect Central Heating Installation Costs?


Type of Boiler

The type of boiler you choose can have a significant impact on the overall cost of your central heating installation. Boiler types include:

  • Combi
  • System
  • Conventional
  • Fuel type (Gas, Oil, Electric)

Combi boilers are generally more affordable to install than conventional or system boilers due to their compact design and simpler installation process.


Type of Boiler Cost Before Installation (UK Average)
Combi £500 – £2,000
System £500 – £2,500
Conventional £500 – £2,750



Different boiler manufacturers offer a range of products at varying price points. Higher-end manufacturers may charge more for their boilers, but they may also offer additional features or warranties that could justify the higher cost.

Size of Heating System

The size of your heating system, including the number of radiators and the complexity of the pipework, will influence the overall cost of installation. Larger properties with more extensive heating systems will typically result in higher installation costs.

Regional Labour Costs

Labour costs can vary significantly depending on your location within the UK. Areas with higher living costs or a shortage of qualified engineers may have higher labour rates, which can impact the total cost of installation.

Complexity of Work Done

If your central heating installation requires additional work, such as upgrading pipework, relocating radiators or installing underfloor heating, this will increase the overall cost of the project. More complex installations may also take longer to complete.


How Long Does Central Heating Installation Take?


The timeframe for installing a new central heating system can vary depending on the scope of the work involved. In general, the installation process typically takes between 2 to 5 days to complete. 

However, this timeframe may be shorter for straightforward installations and longer for more complex projects that require additional work.

If you’re switching to a new heating type that requires a more complex installation, such as installing underfloor heating or converting from a conventional to a combi boiler system, the process may take longer and be more disruptive. It’s essential to discuss the expected timeline with your chosen installer to ensure minimal disruption to your home.


Can I Get A Government Grant For My Central Heating Upgrade?


The UK government offers several schemes to provide financial assistance for boiler installation and heating upgrades:

  • Boiler Upgrade Scheme: This scheme provides grants to homeowners and landlords to replace old, inefficient boilers with newer, more energy-efficient models, helping to reduce energy bills and carbon emissions.
  • ECO Scheme (Energy Company Obligation): The ECO Scheme offers funding for low-income households and those in vulnerable situations to improve the energy efficiency of their homes. This includes assistance with boiler upgrades, insulation, and other heating improvements.
