Not sure if picture has uploaded. I opened up the main incoming box on outside wall to find the tails had been split in a Henly block and into an enclosure with a 100A main switch in it. Out of this there was an armored cable out to a separate building in the garden with a 5-5 split board. The armored gland is on but not made into the enclosure. Just the cores go in !!
Imsuggeting making the armored off into a metal adaptable box under the box and replacing the enclosure with a 80 fused cut out. Any other suggesions apart from run a mile!!! her are 9 ccts in use it as basically been made into an appartent but there is no kitchen

Wrong, wrong, totally wrong.
Do the FMEA's on that design and it is totally unacceptable, end of story, it is downright dangerous.

Its not "wrong wrong totally wrong", its just very bad practice. The armour needs to be earthed to protect the cable, and this can be achieved by earthing at either end if its 3 core, but common sense would suggest that it should be earthed at the supply end so that the earth cannot be broken when a spade goes through it. I cant see how it is downright dangerous?
