What is the cost of replacing an oil boiler?


The cost of replacing an oil boiler can vary depending on several factors, such as the size and type of the boiler, the complexity of the installation, and the location of your home. Here are some of the main factors that can impact the cost of an oil boiler replacement:

  1. Boiler type: As mentioned earlier, different oil boilers are available, and the cost can vary depending on the type and model you choose.
  2. Installation: The complexity of the installation can also affect the cost. For example, if significant changes need to be made to the existing pipework or access to the installation area is complex, the installation cost may be higher.
  3. Location: The installation cost can also vary depending on your home's location. If you live in a remote area, replacing an oil boiler may cost more due to additional travel time and costs.
  4. Additional services: If you require other services, such as removing the old boiler or upgrading the heating controls, this can also add to the cost.


As a general guide, replacing an oil boiler can range from £2,500 to £5,000 and upwards, depending on the abovementioned factors. However, it's important to note that this is just an estimate, and the actual cost may vary based on your specific circumstances.
