i can add loads to the discussion.....Alright, that’s four of you that said it must be earthed. Thought someone might have added something else to the discussion.

What would you have liked adding? The OP didn't ask about anything else, e.g. RCD protection, etc.
I'll add a bit more.I’m running a 15m length of 2.5mm 3 core (twin & earth) SWA to our decking at the back of the garden for a double socket.
Because BS7671 "The Regs" are a right PITA for electricians to understand, let alone Joe Public, sometimes the voice of reason is better understood.Thanks for the decent answers. I made it perfectly clear that I am a DIY’er. I realise that there are a BC & wiring regulations but I cannot justify the £££ needed to purchase them.
I also realise that I need RCD protection and that the cable needs to be buried 500mm down with the plastic warning tape less deep.
I know what traditional ‘twin & earth’ is...what is this then?

If everything is clear in the regs then why have a forum for advice?
Nice cut of tea, and perhaps a biscuit.
Gin is a Girls drinkYou been on the gin again.
Welcome to the forum mate.
I presume you know this work is notifiable, under Part P?
I take it that you will be notifying them. I've been told that this will cost a bit.

Why not ask him for advice, then?...….with all this regular work that you do.My stepson is a sparky & checks all the stuff I do & signs it off. He’s coming over next week to show me how to change the consumer unit!!![]()
I agree both ends, but from design perspective either/or should be used in calculations for a cpc not both.'d prefer to see it earthed at both ends. Also will reduce the loop impedance.
Do you mean an earth rod?I'd prefer to see it earthed at both ends. Also will reduce the loop impedance.
OkNo he doesnt. He means that if you use the armour + one of the cores for the earth then the resistance of the earth path will be reduced.

Harsh but fairFor him to be able to legally sign anything off, he has to be there at specific points in the jobs progress, he also has to be registered under a Third Party Certification scheme, is he?
Who'll be doing the required testing before and after the job and who'll be completing the Electrical Installation Certificates and Part P to LABC notifications?
It's worrying when we hear an amateur attempting a job that can potentially cause death or injury, if not now, but in the future; who doesn't know what they're doing. (Your original question proves that).
Professional, legitimate electricians have had to invest £1,000's in training, test gear, scheme memberships and continual updating of their knowledge and resources. We're professionals for a reason, we know what we're doing, amateurs don't, and with electricity that's a dangerous situation.

The cable is for a socket is it not?You don't need rcd protection for the SWA cable .Have you check with your stepson that you have the correct size of cable for what you are supplying ?
Then fit an rcd socket , the swa cable does not require rcd protection.The cable is for a socket is it not?
Seems like you're being hard headed, is your football team losing?Then fit an rcd socket , the swa cable does not require rcd protection.
... In a country with no Internet or phones it would seemI'm sure the OP's stepson will tell him everything he needs to do.
Not sure why he's here, if his stepson will be signing off everything.
Maybe he's on holiday....

Every cable requires protection!
I'd stick the rcd in a dB for many reasons. If you want I could explain them.
Most rcd socket can't be Ir tested. It's suboptimal at best. Outdoor socket no ability to Ir test = trouble brewing.Nothing wrong in @Flanders post. It's to the regs.
Then fit an rcd socket , the swa cable does not require rcd protection.The cable is for a socket is it not?
Yes there are good reasons for both and im not saying you are wrong . Some cases it may be cheaper to fit an rcd socket than fit rcbo , or there no room in the board to fit an rcd , the list go on , or it could be easier and cheaper to fit an rcbo in the board .I was just pointing out that a SWA cable does not require rcd protection , O and I don't follow the football ☺Seems like you're being hard headed, is your football team losing?

I've posted why rcd socket is a bad idea. Feel free to disagree.Then fit an rcd socket , the swa cable does not require rcd protection.

That what I'm saying i don't disagree you can put the rcd where you like ☺ Just read my post properly in the future ☺ps i did not edit it .I've posted why rcd socket is a bad idea. Feel free to disagree.
I apologise for being harsh on you. I'll make an effort to to be nicer
