My post was locked, I can only assume since I put a link in referring to another site which said it was the gas valve - apologies as I didn't realise I'd broken the rules.

That said I've used this post to now update the solution, for the benefit of others going forward. It's always frustrating when you see a similar problem and no update is provided.
Despite the posts from some very experienced members with saying it was the PCB - simples . It wasn't.
All I did was lower the PCB and circuitory, check all the connections were tight and re-assemble (I'd seen another post suggesting this). I've not heard a peep since - touch wood. Before I did his, every day I'd getting a clicking noise.
For the person who is reading this thread is 5 years time, have a go at what I did. You've got nothing to lose except at least a couple of hundred quid changing the PCB
