UK best way for isolation

[L1Jay1]

ive been asked to rewire 5 flats , each flat is on a card meter, a new cu is to be installed in each flat to cover 3/4 circuits,
a new landlords main board is to be installed by the front door, can each flat be isolated from the main board or does each flat need individual isolation like it is now . What size run of cable to each flat 6mm or 10mm, only one flat has a electric shower , two flats have an electric oven. The flat with electric shower doesn't have electric oven.

as a trainee you should not be expected to design this installation, or install it unsupervised. why have your employers not had the design calculated?

If you connect them from the Landlords board the landlord will be paying for the electric as well as the tenants through their card meters.

It looks like they are at the moment, all of that mess is fed from the T&E in the bottom right of the picture

All of the flats could be fed from a single DB, however it should not be an MCB distribution board. For any hope of discrimination each flat needs to be fed via a fuse or possibly an MCCB.
With that in mind it will almost certainly be cheaper to install a switched fuse for each flat supply.
Then there is also the future convenience of operation to be considered, it will be far better to have seperate switchgear for each flat to allow any future work to be done without disturbing other flats.

The size of the supply for each flat needs to be calculated and the cable size calculated.
If you have been a trainee but aren't now then that implies you are now, and fairly recently, fully qualified so you should have the knowledge to carry out cable calculations far better than just guessing at 6/10 maybe.

Be interesting to know how the electric is being charged if tenants have card meters and it all runs through the Landlords meters.
