How much does boiler replacement cost? Boiler replacement is a significant investment, but it’s one that can increase the efficiency of your heating system and lower energy bills in the long run. The cost of replacing a boiler can vary widely depending on the type of boiler you choose, the size of your home, and whether any additional work is needed (like upgrading radiators or pipework). In this guide, we’ll outline the key factors that influence boiler replacement costs and give you a general idea of what to expect.
Factors That Affect Boiler Replacement Costs
How Much Does Boiler Replacement Cost
- Type of Boiler – How much does boiler replacement cost?
- Combi Boilers: These tend to be the most affordable option. A straightforward replacement of a combi boiler typically costs between £1,800 and £3,000, including installation. They are ideal for smaller homes with lower hot water demands.
- System Boilers: Slightly more expensive, system boilers are better suited for larger homes. The cost for a system boiler replacement, including installation, usually ranges from £2,000 to £4,000.
- Regular (Conventional) Boilers: If you have an older home with a traditional heating system, replacing a regular boiler will cost between £2,500 and £4,500, as these systems often require additional work like replacing the hot water cylinder.
- Size of the Boiler – How much does boiler replacement cost?
- The size (or power output) of your boiler is measured in kilowatts (kW). Larger homes with more radiators and bathrooms require boilers with higher kW ratings, which can push up the cost. For example, a small flat might need a 24-30kW boiler, while a large home with multiple bathrooms might require a 35-42kW boiler, which would be more expensive.
- Installation Costs – How much does boiler replacement cost?
- Straight Swap: If you’re replacing an old boiler with a new one of the same type and location, installation is fairly simple and costs less.
- Changing Boiler Type or Location: If you’re switching from a regular boiler to a combi or moving the boiler to a different location, this will increase labor costs. Expect to pay an additional £500 to £1,500 for more complex installations.
- Additional Work – How much does boiler replacement cost?
- Upgrading Pipework for Radiators: If your current heating system is outdated, you might need new pipes or radiators. This additional work can increase costs, potentially adding £500 to £1,000 to your bill.
- Smart Controls: Many new boilers are compatible with smart thermostats, like Hive or Nest, which allow you to control your heating remotely. Installing these systems can add another £150 to £300 to the total cost.
