10KW to 9.8KW Shower

The installation was signed off by elec. board.

Really?

The EB's used to offer electrical services up until around the mid- late 90's.

I don't see a spider's web as far as it concerns the shower installation of 10 years ago.
The main question here is the issue of the MCB size....

Thank you! How do I check MCB size?

It will have it written on it, such as B40.

e.g.

It is a 40A Type B Switched MCB.

Orange switch = 40A

Pinzy: You could improve that arrangement at very little cost by fitting a mini-consumer unit - such as the "Square D" shower supply enclosure (approximately £24). It comprises a 63A/30mA RCD and a 45A MCB.

The work would necessarily entail the pulling of the main service fuse, which, depending on your 'skills', you might decide to leave to an electrician.

Are you sure, by the way, that the shower cable is 10mm and not 6mm? I've seen your photo of course, but my eyesight isn't what it used to be....

Thanks for your suggestion and Yes I would leave to an expert...not ready to die yet

I say it's 10mm as that's what's written on the cert which the EB did. Visually, it is a monster of a cable close up and a bugger to bend.

Maybe I can take a picture at the weekend but quite sure we have 10mm cable.
