Thanks for your reply. I have already arranged for an engineer to come over, but I'm not sure if they are Gas Safe registered engineer. I will certainly find out!
Hi all. First of all - I am a total newbie when it comes to DIY and I have never did much of it, so apologies for any silly questions. Me and my girlfriend have recently moved into a 2 bed house with CH. We've previously lived in a flat which had electric heating, and so I don't really know anything...
