Yes, it must be Earthed.
Make sure you use the correct glands, properly, as well

i can add loads to the discussion.....
1. why do you ask when it's clear in BS7671?
2. is it being installed by a competent sparks?
3. where's my beer? (this Q for missus, as she's only doing washing, ironing, washing up, dusting, cleaning, women say they can multi-task, so why my beer not within reach?
What would you have liked adding? The OP didn't ask about anything else, e.g. RCD protection, etc.

Nice cut of tea, and perhaps a biscuit.
I'll add a bit more.
SWA cable is not "twin and earth". SWA cable is 2,3,4 core etc. All cores are separately insulated. You may choose to use one of the cores for earth. Or you could use the steel armour (subject to a number of tests, calculations and checks) as the earth.
The flat stuff that is used for fixed wiring inside a house , like this
is twin and earth.
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?

Because BS7671 "The Regs" are a right PITA for electricians to understand, let alone Joe Public, sometimes the voice of reason is better understood.
You been on the gin again.
Gin is a Girls drink
Thanks Spoon - yes, I know.
Arh but you see, it early use was for inducing bravery on the battlefield.
Besides which, red wine just makes your teeth red & breath stink.
PS I'm not biased

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.

Do you mean an earth rod?
No 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.

For 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.
"any idiot can get a circuit to work, but it takes knowledge to get it to work safely"
Harsh but fair
The regs are there for a reason mainly to stop people and animals being killed, but why not ignore them and take a chance it's only red tape
The cable is for a socket is it not?
Then fit an rcd socket , the swa cable does not require rcd protection.
Seems like you're being hard headed, is your football team losing?
Every cable requires protection!
I'd stick the rcd in a dB for many reasons. If you want I could explain them.
... In a country with no Internet or phones it would seem
Most rcd socket can't be Ir tested. It's suboptimal at best. Outdoor socket no ability to Ir test = trouble brewing.
What I said about every cable requiring protection is true. He said the cable did not require rcd - very misleading
I misread or he edited his comment. I thought it said cable did not require protection. Not rcd protection
Then fit an rcd socket , the swa cable does not require rcd protection.
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 ☺
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
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 .
