LOL., it looked a bit scary at first, i put a pic up under the post "Challenge", rat's nest of tails. i've replaced the old switch fuse units with a 10 way split board, feed to DB3 from a 63A non-RCD MCB, RCD for 5 circiuts., upgraded the existing 14 way board at the bottom to dual RCD. just waiting for scottish power to see if they can PME the job as it seems to be on a rod that is behind a partition and inaccessible. the existing board was a disaster. 2 2pole isolators, no RCD, earths and neutrals stuck in anywhere, cpc's of different circuits twisted together in one sleeve, 2 cpc's not even connected in the board. was expecting to find loads of faults, but luckily, the pudding that fitted the board just connected the existing wiring, which dates back to 7/029. will finish boards off this aft. and then tomorrow go round all fittings T&I. got a 3 hour window i can isolate boards.
