Thanks for all your responses and sorry for the delay in replying. Some people seem to be very annoyed. It wasn't my intention to start any arguments, more to try to understand the situation with my limited knowledge.
For the poster (Joe1977) who suggested switching off the fused spur. I'm not going to touch anything because the electrician did a temporary fix (which I don't understand) and I have electricity. I'm scared if I start meddling with things, it'll all turn off again. Interestingly the RCD is down, although the electricity is working - which I didn't think could happen.
My main concern is still the boiler and trying to find out about this mysterious valve. Does anyone know what valve it might be, that would cause a boiler to not let the heating work and to make a bang sound as it switches off?
I don't have a service plan with the current company and they haven't let me know about any charges except for saying that a new pump would cost a couple of hundred quid.
I've contacted 3 other firms now in the hope of getting a second opinion.
