PPS and you need to consider how you will run the new tails into new CU, without having to afford RCD protection, i.e. you can't flush them in.

Mmm, good point. I would utilise the old ones if possible.
 
Indeed thus trunking. That would be compliant? (Ugly as sin but compliant).

Hopefully the current tails are long enough in which case I only need to replace the earth conductor for 10mm^2?
 
We are definitely in agreement that if I replace tails I only need to replace to the switch fuse? Similarly wth the main earth to the connector?
Without the 60amp switchfuse (take it's 60a?), you would have to size the tails to main fuse, 100amp - 25mm tails. Also depends if you mate adds to the swanky new CU you going to install for him in a few years, 10.5kw shower and a hot tub!

Nice bit of 50x50mm in the corner behind the door would look okay, floor to ceiling?

The switch fuse is 60A. If I need to run new tails (hopefully not) I'll run 25mm^2 so if upgrades are wanted in a few years that take us above 60A then we can arrange for supply upgrade

Let's hope current tails are long enough then. Pulling a 10mm earth through cavity will be ok? Or should I go trunking route for that? Would you contact dno to upgrade all the way to cut out or just to the connector?
 
If it was me. New WPD isolator. You can then do you bit at your leisure! New 25mm tails & 16mm earth conductor run horizontally through the wall (in flexible conduit) into hallway, then into trunking into ceiling back done in trunking, into RCBO populated CU or High Integrity CU. But then its not my money we're spending. Now that's it, off to the galley. :gru:
