The cost of installing a new boiler can vary depending on the type of boiler, the complexity of the installation, and any additional work required.

Below is a general breakdown of what to expect when budgeting for a boiler installation.

Typical Boiler Installation Costs

  • Combi Boiler Replacement – £1,500 to £3,000
  • System Boiler Replacement – £1,800 to £3,500
  • Conventional Boiler Replacement – £2,000 to £4,000
  • Conversion (e.g., System to Combi) – £2,500 to £5,000

Factors That Affect Boiler Installation Costs

  • Boiler Type & Brand – Premium brands and high-efficiency models tend to cost more.
  • Installation Complexity – Relocating a boiler or upgrading pipework adds to the cost.
  • Additional Work Required – If your home needs a new flue system, thermostats, or radiators, costs will increase.
  • Gas Supply Upgrades – Some properties require an upgraded gas pipe, which can add to the overall price.
