House currently has a 7KW shower on a 30A MEM rewirable fuse in the full rate CU. If this is upgraded to a 8.5KW unit the old consumer unit could be renewed to provide a suitable MCB. There is also a modern Total Control split load consumer unit which includes a section for 24 hour equipment such as a focal point fire. Is it acceptable to run the shower off this Total Control supply? This would make the job easier as it would merely need an additional MCB.

Total Control

What size is the cable?. You cannot simply uprate the mcb!
Sounds like a split load for an economy 7 supply...... ?
Unless you only want shower between the hours of 00:00 and 01:00 and 02:00 and 07:00 I would keep it on the peak tarrif CU.....
maybe readin wrong of course......

There is a normal meter going to an antiquated fuse box which currently supplies the sockets, lights, cooker and shower. There is also a Total Control meter going to a modern CU which is split 3 ways. One section is for cheap rate water heating, another for storage heaters and another which provides 24 hour electricity. This 24 hour section currently goes to a boost timer for the hot water and also a focal point electric fire in the living room. There are 2 spare MCB slots in this 24 hour section and all I am trying to find out is if the shower could also go on there.
Yes, it could. Assuming the tails feeding that part of the CU are sized adequately - 16 or 25mm would be fine.
