I presume the tw*t you are refering to is the original spark who rediculiusly condemned the shower. If so i concur.What a tw*t!
That drives me mad!

Doing some calculations, I don’t agree with your tenants electrician. A 6mm cable, clipped direct will be absolutely fine on a 40amp mcb. The only issue is if the shower circuit is not on an RCD. Providing the run isn't miles and miles.
Putting a 32amp mcb in the circuit will just cause annoying tripping as the 8.5 kw shower will draw around 36amps.
apart from all the good advice given so far, as long as the 6.0mm is installed as ref. method C, i.e. it can safely carry 47A, ( Ib<Iz ) then aas the shower is a fixed load, overcurrent protection is not required so a 50A MCB could be installed. 433.3.1 (ii). (BYB 17th).
Agree it does not need changing, and probably better not to. Not so sure 36 amps would cause the overload part of the breaker to nuisance trip though, looking at the curve for it.
That would be one seriously long shower!
.....
● 8kW - 40amp
● 8.5kW - 40amp

Thank you Tom for the advice seems like plan.Ask her to get her electrician to put it in writing also quoting BS as well as his or her part P approval body.
Then armed with the said information ring the help desk of the said body (they all have a help desk), quote their number etc and speak to them they will give you 100% the answer. Ensure your tennant tells sparky what you are doing. If he is fully approved and he’s correct he will not hesitate in supplying the information.
Thank you for your comments, I just want my tenant to have a safe home they can enjoy after all the do pay the rent.One things for sure they should be greatful they have got a landlord that cares, the fact you are investigating there concerns rather than just saying hey it works what u complaining about shows you care not to mention new cooker
I have since found out from the tenant that he did not even go upstairs to look at the shower so has no idea about it's power rating.One things for sure they should be greatful they have got a landlord that cares, the fact you are investigating there concerns rather than just saying hey it works what u complaining about shows you care not to mention new cooker

Sounds like the electrician needs to look at the books a bit
The length of the run is 8 metres and there is a 30ma rcd in the consumer unitDoing some calculations, I don’t agree with your tenants electrician.

What is even more worrying he said that instead of connecting the cooker with 6mm cable he should really be using flexible multi strand cable like on her kettle or halogen cooker.
I have never heard of this can anyone please enlighten me.

and maybe retrain as a plumber. they ain't got a clue about electrics anyway, so he should feel at home.He could have used 6mm flexible cable or 6mm T&E cable, assuming that 6mm is the correct size. Either is perfectly acceptable as long as it is correctly installed.
I think this electrician needs to brush up on their knowledge of the regulations!
He also said that the 40 mcb for the cooker should be changed to a 32. As I understand it the principal of diversity could be applied so that could be ok but would a 40 mcb with a 6mm cable over a 7 or 8 metre run be dangerous clipped direct not in insulation?and maybe retrain as a plumber. they ain't got a clue about electrics anyway, so he should feel at home.
