maximum demand, main fuse and tails

[adam.h]

Ok, installing a new cu, leaving old one in place. They currently have 60A main fuse. With the new demand added the total MD is now 86A.

Do I just ring up the supplier and get them to change the fuse and meter tails to 25mm where needed. Can I then keep the 16mm out of the henley block to each cu as individually they are lower then 60A?
Will this be a cost to the customer or do the suppliers pay for this?

thaaanks!

You would reallly need to speak to the DNO about the propsed changes upgrade of tails is the customers responsibility the DNO stops at the meter unless as some do an isolator is put in then it would be the customers responsibility from isolator to CU.
