conservatory wiring

[pjb1]

Been to look at a job today for a builder who is putting up a conservatory for somebody, The property owner wants a light and a couple of sockets putting in. Problem started as soon as i started looking, Old wylex consumer unit fuses removed and replaced with push in type mcb. No spare ways in the Cu Main Bonding under size.
Looked at the main incomer to see if i could maybe come off the tail side to feed a small 2 way Rcd protected consumer unit. But can't see a way of tapping off?

And Help and Advise would be greatly appreciated Fellas

Supply is T-n-c-s
100A main Fuse
25mm Tails
16mm Earthing Conductor

Can't you use a Henley Block? Or maybe update the CU? About £80 for a Wylex from Screwfix.

what about spurring it of from a jb for the lights? and make a spur for the sockets from other sockets in house?

Any additional work must be to current regs which will mean RCD protection.

The main earth and main bonds will also need to be upgraded.

Whilst there are still numerous old CU's out there, it makes "just adding" an expensive job sometimes.

Perfect opportunity to price a CU upgrade, beware of John Wayne sneeking up from behind and seriously undercutting you, though.
