    I'm looking to buy an ex-council flat with this circuit board. Will this be difficult?

    I've never seen such a 'vintage' board so I'm not sure what to think.

    It's quite likely that it will need a rewire, have you had a electrical test done ?,

    no - i'm looking to buy this flat. Its a 60s concrete tower block.

    A builder friend looked at a socket and thought they were old because 'it has a red wire'

    Will this type of circuit board be more expensive to rewire because it's so old?

    If the wiring is original (1960s) its gonna need a rewire.
    Just because its red and black does not automatically mean rewire.

    Loadmaster dorman smith were good boards in their day, but not DIN rail so only thing that will fit is loadmaster, however likely you will want a new all RCBO board anyway with SPD so hardly matters what make or model, you will in order to add anything need to change the board.

    Around 1966 there was a big change, after then lights have earths, and mainly PVC cables, before then likely to find rubber cables and no earth to lights, I was still using those boards when working on the building of Sizewell 'B' so early 90's still in use.

    It would be prudent to get an EICR (electrical installation condition report) done.

    The board can be still used with owner occupier, but to get a satisfactory result to rent may be a problem, an EICR is a personal opinion of the inspector, so you can ask him first if he will pass the board or not.

    I still had fuses in this house when I moved in, within 6 months new CU fitted, no sweat, what I expected to do, the problem arises when you want to rent, and you need an EICR before you can rent it out.

    I do not see lack of RCD protection with a TN property as potentially dangerous, but I would with a TT property, as the water and gas pipes are now mainly plastic, so with a TT the earth rod on its own is not good enough.

    But there could be other issues, so prudent to get an EICR done.

    Very helpful. i should i assume it will need rewiring. Get it over with

    Will this be a more difficult wire job than usual? I won't need a specialty electrician to work with it?

    Does the building being concrete make a big difference?

    It could be very easy, if its wired in conduit you can rewire through the existing conduits/ maybe.

    If not it could be a pain.

    Best bet is as others have advised get a condition report done before you buy.

    I would wage a bet it is a complete rewire that you will need. These concrete flats can be a total nightmare to rewire as the runs of existing conduit is rarely where you need it especially if you need sockets or lights in different places to where the existing are already in place. Not a nice job to do and will be very messy so if you do buy it make sure it is the very first job that you do to modernise it.

    If that is the case, then you really do have much bigger potential problems than just the electrics.
    Has the tower block been clad in the last 20 years ? If it has, walk away now, it dosn't matter how cheap it is now to will cost you the rest of your life to pay for it and you will never be able to sell it.

    I would drop the ceiling a few inches and run cables and any pipework in that it will end up a far neater job

    Only problem I foresee with doing that is if he has a pet giraffe and it could cause problems with head room. Seen that a lot.

    Any decent spark/builder would ask the giraffe question before lowering the ceiling.
