Question about reinstating socket in shed

[kissinger]

I’ve had a partial rewire and the electrician removed the old shed socket because the shed was being demolished. The original 2.5 mm² T&E that supplied that socket is still in place from the kitchen to the shed location, and it forms part of an RCD-protected socket circuit at the main consumer unit. Now that the new shed is installed, I want to reinstate a socket by fitting a BG Nexus Storm IP66 13A weatherproof RCD double socket directly onto the end of the existing T&E. I’m not creating a new circuit; I’m simply putting a socket back where one used to be.

Before I go ahead, I’d like a second opinion. Is it acceptable to terminate the T&E directly into the weatherproof socket without adding anything else? Are there any safety or regulatory issues I should be aware of when reinstating the socket on this spur?

I am aware that armoured cable is preferred, but the T&E is already installed underground with a protective sheath and I don't fancy digging up my patio (it's crossig a roughly 2m stretch of patio to the shed). Any advice appreciated.

1) Location, Wales likely need to register the work, England no longer required I think.
2) Unless using a 10 mA RCD socket then pointless fitting a RCD protected socket when already RCD protected.
3) Twin and earth not rated for external use, but as long as it passes the testing then I would not be too worried, however for my own shed used SWA and have abandoned the old twin and earth.
4) As long as nothing goes wrong, no one is likely to question what you have done, if something does go wrong then paperwork will be asked for, so unless a very poor job even if it does not comply then unlikely to get caught.
This from the IET is rather dated 2005 however not that much has changed, unless you are going to charge an EV from the shed, or install solar panels, then following the 2005 instruction set and you will not go far wrong.

I can't see an issue. You are in effect just replacing an accessory, like for like.

But if you are in Wales, it is notifiable.

What I would be tempted to do is protect the cable (my choice would probably be black PVC conduit) where the cable comes out of the ground so it is protected against damage from tools etc...

There's not much point having two RCDs; either one or the other (or both?) could trip. Don't imagine that the more-downstream RCD will always trip first.
