Are your prices really fixed?
Yes they are.
When using our fixed price quote tool we need you to be as accurate as you can, but don't worry there are no tricky questions. If it looks like your boiler might be in a hard to access location we'll ask to give you a call before we firm up the quote - but for most people we won't need to do that.
All of our new boiler installations come with a chemical flush (to make sure your system is nice and clean) plus we also include new heating controls when they are needed, a new flue, filter and if there are any upgrades needed to your pipework to bring them up to the latest safety standards, we'll also cover that.
