I am having an extension built on the back of my house which was going to involve moving my combi boiler to a new outside wall. I have since discovered that the flue can be extended and I don't need to.
Given that I applied to building regs with the moved boiler on the plans, do I need to reapply if I don't go ahead and move it? I'll hvae a qulaified gas fitter do the flue extension
Thanks
