Conforming with regulations?

Hello, I have 2 questions about the practical approach to meeting regulations.

I have just requested an electrical safety check which the property has failed with a number of C2 faults. I have asked for an estimate for rectifying the faults which the electrician is preparing, but he has said that he can’t do the work until the new year.

That leaves me in breach of the law as the faults should be rectified within 28 days.

Chatting informally to another electrician he said they don’t like checking each other’s work and if he was to take it on he would have to start again with all checks.

Any advice please?

2nd question. If major repairs are necessary, maybe hypothetically electrical or maybe mould (we don’t have any), can this be grounds for a landlord to evict a tenant in order to carry out the work.

If not, how are we supposed to get it done?

Thank you,

Bob
