The twin and earth glands have in most cases IP66 or IP68 ratings for water ingress. No requirement what so ever in the circumstances these are used in!
I have just searched for specific glands for twin and earth and the rubber component in the gland I have used are not shaped for twin and earth cable. They have a circular hole which I assume is optomised for round cable. These multipurpose glands I used are to secure the twin and earth in the...
Two things that I have seen but not really noticed until recently!

Sorry I did not mention my home lift is wired with 6mm twin and earth possibly a bit on the heavy duty side.
On the original garage we were talking about, I would have used 4mm twin and earth with a C16 breaker but it was wired by someone else two years ago.

I put a clamp meter on it the other day as someone brought one along with them, it recorded 20 amps at startup and went down to 12 amps after say 10 seconds. I 'm well aware that inexpensive clamp meters have a start up lag before...
That sound more reasonable than the boilerplate guidance, do a final check of what max load could be expected to be put on each of the two sides of the garage, then run each side of the garage sockets with a 20 amp breaker via 2.5mm twin and earth.
Thank you both!
Thanks for the reply, the guidance on radial circuits seems to be for a a maximum of 50sqmtrs floor area per for 2.5 twin and earth radial circuit with a 20 amp mcb or 75sqmtrs with with 4mmsq twin and earth radial with a 32amp mcb or as you suggested rcbo's to stop the rcd switching off all the...
The garage is 17 mtrs x 15 mtrs in the UK
The house has a 100 amp supply to the house consumer unit.
The garage consumer unit is fed from a 63amp RCD to a 40 amp B rated mcb in the house consumer unit.
The feed cable to the garage is 10mmsq SWA 3 core with the swa bonded to the earth...
