With respect "IQ Electrical" - I think you have missed the point of the question - I am not familiar with the 16th Edition regulations ( before my time ) - but I imagine bonding of sinks etc in kitchens to be necessary.... I think this is more a question of whether you should still be testing to the 16th edition at all. I would strongly advocate putting in an RCD ( whether that be a new consumer board - or how-ever ) - and then testing to the 17th edition.
The customer would reasonably expect a SATISFACTORY on a report to mean that he could extend the circuits - and testing it to the 16th edition would mean that a SATISFACTORY wouldn't indicate that extension of the circuits were possible.
So to answer the question - MY ANSWER would be a FAIL with the recommendation to get the consumer board up to the 17th Edition - before doing anything else....
