While PA testing a couple of holiday lets I noticed that the stainless steel kitchen worktops were not earth bonded and wondered if they should be. All the workshops, commercial kitchens I've come across have had bonded worktops/benches. Thanks.
Stainless steel kitchen worktops

where's the risk going to come from?
Bonding sinks stopped a long time ago. Commercial kitchens tend to have all surfaces made of stainless steel, and lots of electrical items on them, so there's a much higher risk of a short to the surfaces.
A faulty appliance being in contact with the worktop I guess.
Thanks.
so.. if its class 2 then it can't become live. if its class 1 then it'll be earthed. end result of a fault would be the same if the bench was earthed or not
I would think if the supply has RCD protection it’s not a problem, but if not, supplementary bonding should be in place.

Waste disposal unit, Under Sink Water Heater?
My question has already been answered but thanks for you input.
you mean 'its not the answer i wanted, but thanks anyway'. sounds about right.
I really just wanted to know what was the best practice regarding installation of metal worktops. Maybe I should have been more precise in the wording of my question.

It is probably a microscopic minority that actually find that a possibility.You'll get used to Andy, eventually

You absolutely should. It's a bit like talking with my Mrs, I often explain if something could be taken two ways, it was the other way I was meaning
He says it as he sees it. I have no problem with that, I like completely honest people, they are far easier to deal with than meeley mouthed politician types.

The 15th edition IEE regs required everything that did not move to be bonded - if it did move bond it just the same - this led to metal window frames and fireside tongs and pokers also being bonded.
The 16th Ed was a complete reversal and required insulation as opposed to bonding - i.e kitchen sinks to be insulated from metal pipes and taps and not presenting a hazardous large area of bonded metalwork.
Domestic Kitchen sinks to be insulation tested between metal pipes and taps for no earth connection. The cpc connection in the flex cord of a waste disposal in fortuitous contact with the sinks is deemed adequate bonding.
The aim being not to introduce a large area of earthed metalwork exposed to touch
