Dead bugs and debris coming out of hot water tank.

The fortic tank has been cleaned. What is the heating header cistern? The plumber used a wet vac

If it feeds the heating system, surely that should have been cleaned out and had a lid fitted when you had a new boiler last year?

Hmm good point. Do British gas usually do that?

Pictures of cold tank in the loft (disgusting I know)

Can't get pictures inside fortic cylinder ATM But will soon

Both tanks, should have lids on them, in part to keep dirt out, but also to help reduce the moisture evaporating out of them. Before fitting a lid to that loft header tank, it needs a good clean out.

Any heating engineer worth his salt should make sure the system is clean before fitting a new boiler. The header tank is part of that and usually contains plenty of muck. I’d be surprised if the manufacturer would entertain a claim for a fault if it found all that muck in it.
