Twin&earth and SWA installed loose on floor

[StigOfTheDump]

Hi All,
The contractor working for Magnet Kitchens at my brother's house has run the sockets ring in 2.5 T&E, plus an SWA for the cooker supply, by laying these cables on the floor under the units.
I'm fairly sure this isn't acceptable - at least these cables should be clipped up against the wall (shouldn't they?).
We had actually expected the cables to be chased into the wall before the units were fitted, but they've done the electricals and plumbing after the fitout...
Any thoughts or comments? Many thanks.

To the person ordering the work.

Hum ..... let me quote from BYB p416

"If you are the person ordering the work, but not the owner of the installation, you should pass the certificate , or a full copy of it including the schedules, immediately to the owner"

a quid says thar SWA is 6mm 3 core. any takers?

No mate you're on a winner there

I'll take your pound. I'm going for 4mm 3 core.

I can't stand the excitement.

Does no one have safety concerns for the spider in the pic?

The armoured cable looks small, I'm going to say it is split concentric - size unknown...

I thought concentric cable was only allowed to be used by the DNO. Is it allowed under BS7671 if so which table?

So... my brother cannot see the spec of the SWA embossed on it anywhere, but has just measured the OD of it: actually only 12mm.
By my reading of the datasheets, that makes it 1.5sqmm x 2 or 3 core.
So the CCC of SWA is much higher than that for the equivalent T&E (or tri-rated cable that I'm familiar with), but 1.5 still tops out at 27 or 29A, and I'd like to bet that the MCB is 32A rated...

Also, we can now confirm that there is an SWA gland into the CU, but no gland into the isolator - which is fitted in an inaccessible void behind a kitchen cabinet, so is no use as an isolator i.e. just functions as a terminal box...

Think you are all forgetting who installed this cable, my take 2 core with a clip on the armour at each end for the cpc

Measuring the diameter is a bit hit & miss, a competent sparks would be able to assess the conductor size. In your picture, the swa looks bigger then 12mm OD, comparing it to the tw&e cables?

The isolator in 'an inaccessible void behind a kitchen cabinet', could you explain more, how is your brother expected to isolate the cooker?
