yikes, sounds like i have been badly advised
Only alternative i can think of would have been to replace the 32A fuse to 40A which i saw on
Screwfix direct.
Which would limit you to a 9.6kW shower, not a 10.5...
But to confirm if the fuse is correct one to fit, will i not have to cut the fuse box seal to get into it ? ( unfortunately i cant see my fuse box as im not at home just now)
There is no seal on your fuse box. The seal, and fuse, I was referring to is the main one on your supply, before it goes into the meter.
also will the shower kit not wire up into where it is now but of course it will be fused thru the additional shower fuse box ?
Not sure what that means, but irrelevant now...
The tails i was supplied are 25.0 blue/grey ( 2 of them) and 1 16.0 green yellow earth cable.
Sorry - missed the mention of tails in the 15:47 post. And it should be 1 brown, 1 blue..
You're missing a service connector block aka Henley block, which is basically a large, high-current junction box.
The idea is that the tails that come out of the meter and go into your fuse box are moved, and go instead into a Henley block, and from there two sets of tails come out, one goes to the existing fuse box, and the other to the new mini-CU for the shower.
Obviously for this to be a safe task, the supply has to be isolated via removal of the electricity suppliers service fuse.

Good idea.
