He inspected it and he has had electricians to inspect it but I'm getting everything second hand from him and none of it that clear, honestly. He tells me I need a 10 way consumer unit with 17 double sockets to replace what I have.
sounds like he's starting to take advantage of you. Id seek out a second opinion from ur own electrician and speaking from previous experience dont let them do more than what u have asked them to do.
