Cottage fed from pub next door.

[GBDamo]

The old landlord and owner has retired into the adjoining cottage. This cottage is fed from a 100 amp isolator that is Henley blocked off the meter tails from feed to the pub. The feed cable to the cottage is 16mm t&e and runs about 5-10m and feeds an old wilex rewireable fuse box. From a fuse in this board another 16mm t&e runs for about 10-15 m to a plastic non-RCD CU.

Assuming(I know) that the Ze and Ze at the CU are good I plan to swap two MCBs in the CU to run two new circuits in protected by compatible RCBOs.

Now if all tests ok I'm happy with the work I intend to do however I don't like the set up as is and have suggested that as a minimum he should look at some kind of additional protection in the form of an RCD.

Is this reasonable?

I'd look to put the RCD between the 100amp isolator and the original fuse box.

Other than nuke it from orbit, any advice.

Surely a residential place separate from the pub should have its own meter? The discrimination is poor with the wylex presumably next door if that goes he is going to be stumbling around in the dark. I would suggest a supply separate to pub. The 16mm² on a 100a main fuse doesn't sound good. As observed by @westward10 the connection into the wylex sounds very bad. I would not put or modify any circuits in the preceding description of the set up there. Too many what ifs.
