Be best if we knew where you are located, we have a few decent plumbers on here, but I can’t see them travelling too far they only have old buses!
I’m afraid a bit far for me at the moment as no immediate plans to visit my brother down there. I just looked on Gas Safe Register and there’s a few folk in Bexley. Not sure what they’re like tho. https://www.gassaferegister.co.uk/f...HX1oj9qX9z5mugu5paplJYiVpO5uWGp2LG0uG0wYAxA==
