Is this 10mm?

[IAMCALLEDDDD]

Hi all, I need some advice- I'm no electrician, i'm just wanting to know the cable size i have in existing shower- Had a look in attic above shower and have attached pics of the cables against a measure (starting at 10 cm/ tape was broken)

Can anyone confirm of these are 10mm or 6mm please?

Wanting to know what kw of shower my cable can carry si i can buy for the electrician to put in.

Many Thanks,

That's got to be 10mm hasn't it? Is there any 6mm twin and earth cable that has an earth like that? If so, I have never seen it before.
Is there any imperial cable that may look like that and be <10mm?
