Boiler pressure drops to 0 over a couple of days!

I'm not fearful of calling someone out, I just wanted to know as much as I could first.

The guy I have used in the past said even a basic repair with replacement parts would be £200. Just didn't want to waste money on something that is going to go wrong continually.

Cheers for all the advice. I'll get someone in to look at it.

It all depends on whats wrong what it will cost.

Some causes might be less that £150 if I was doing it.
