Surely somewhere between your solicitor and the vendor this should be sorted. Solicitors get paid a lot for their services - if they didn't get all the information requested and there was this hanging electrical LABC activity they didn't pick up on, surely it should be for them to find the vendor to sort it. Is there more than one solicitor at the practice -or even a solicitor's practice manager to complain to?
I'm no lover or protector of solicitors, but I'm not sure that one can really blame them in this case. A solicitor surely has to work on the assumption that answers to enquiries from the vendor (or vendor's solicitor) are truthful. If the vendor answers 'No' to the question about electrical work since 1.1.2005, then I can't see the buyer's solicitor can do anything but assume it is the correct answer - and therefore have no reason to look any further. If solicitors assumned that all responses to Enquiries before Contract were lies, and therefore had to 'investigate' every one of them, the conveyancing process would become ridiculously protracted and costly.Write a letter detailing your concerns to your solicitor. Ask him why this issue has not been boxed off before completion. Tell him to rectify the situation to your complete satisfaction. If he does not, contact these people:
Kind Regards, John.
