What does it cost to install a Viessmann boiler?

Here are some cost estimates for the various Viessman boilers on the market, including both supply and installation costs:

  • The average new combi boiler cost is £3,000
  • The average new gas system boiler cost is £2,700 
  • The average new condensing boiler cost is £2,500

Viessmann is one of the UK’s most popular boiler suppliers, offering a range of gas boiler types, and installation costs vary depending on which one you need.

Figuring out your new boiler cost first involves choosing a boiler type, whether it’s a combi, system or condensing boiler.

These prices can vary depending on a few factors, with the most important being whether you’re swapping your old boiler for a different kind of system or a like-for-like boiler, with the latter being the cheapest option.

When looking for a contractor to install a new Viessman boiler, we recommend getting at least three quotes so you can compare prices and get the best deal.
