NYY Buried Cable - Legit job?

[OsramMyers]

Hi, Ive had a NAPIT qualified electrician out to install a new feed to the garage along with a new consumer unit in there. Its a short distance of around 6m and the cable he used was a 16mm NYY cable, it has been directly buried around 300mm depth with yellow warning tape, It goes under a few paving slabs but mostly its a graveled area.

Is this installation totally 100% in accordance with current building regulations/standards?

When he came to quote I asked for armored cable, he even specced SWA in the written quote but on the day I noticed it was this NYY cable. He said its all OK and he has passed the Part P certificate onto my local authority. When I questioned him after the job he said its easier to use and bend and things have changed over the years and this cable is fine to use in the installation. He said there is no price difference too.

What are people's thughts?

The Hager was installed a few years ago when we had AC installed. The consumer box to the garage is the larger SWA. He could not terminate into the Hager hence the plastic box. It does look like there is an earth wire from the gland.

At the other in the garage there is an earth wire coming off the gland. I cant see if the steel wire is connected to the gland but you would assume it is. I isolated the electrics before taking this photos.

The armour of that SWA appears to be earthed.

Blue crimp on 4mm2? PVC insulating tape on joints? Equipment in DNO box?

It's not great is it? I paid £875 for this installation too. There was a bit of fiddling around in the garage too connecting the sockets and lighting circuit . He was here for 5 hours on the first visit then 2 hours replacing cable to SWA, I was expecting a thorough 2 days for that price. He is a definite NAPIT registered electrician. He had such a well-organised van as well! I had high hopes. He gives NAPIT a bad name, goes without saying he will not be used again by me nor recommended.

It is rough but the armour would appear to be earthed. That adaptable box in the meter cupboard could have been mounted externally butted up to the cupboard with the swa into the bottom. Who connected up the garage consumer unit as those cpcs look pretty rough and as above that blue crimp is not suitable for 4.0.

I did not want that plastic box on the wall, this meter is right next door my front door I told him to put that in the meter box. He said it was too difficult to terminate straight into that Hager. Either that or he couldn't be bothered.

It would not have been easy to get the swa into the Hager board and without physically being there it is difficult to judge. If it were me doing the job the box would have been external to the cabinet whether the client liked it or not.

It's earthed both ends. The garage end is metal box and has earthing nut. The source end is a bit rough.
But if he was told he can't put the box on the wall I have more sympathy.
I agree with him that I wouldn't want to be getting the SWA into the existing Hager - the bottom face is the only option and it looks too busy.

Bit rough and agree on the blue lug also
But seen a lot worse TBH £875 seem a bit steep but not overly

 

[hasel5]

Lack of labels as well

Standard builders wiring

it’s ok as it’s a tough cable so all gravy

It's rough but I've seen a lot worse. More untidy than anything.
