Hi guys
A good mate of mine has a fair sized building company in London and has landed a major contract in the social housing sector. He is looking to sub work out to a team of guys experienced in this work. It's all kitchen and/or bathroom refurbs plus some internal wall insulation...
If you cant resolve it amicably, call Gas Safe for a free inspection. The boiler may well be installed to spec but nuisance pluming must be taken into consideration.
Just got my certificate through from Gas Safe / Building Compliance. Part of it says " It is a legal requirement for anyone carrying out any gas work on your behalf to be Gas Safe Registered."
Can't believe that a "qualified plumber" and an "rgi" can't figure out between them how to do this.
Best of luck with the boiler. And best of luck with the Vaillant.
