I really wouldn't be too fussed about the rules but this guy must be completely and utterly clueless if he thinks it's ok to connect lighting directly to a 32A ring. I mean, come on, it's just common sense to anyone who knows anything about electrical work.
The only way that would be even slightly acceptable is if he locally fused each lighting circuit and set them up as fused spurs off the ring main and even then it would be weird.
Don't you guys have to keep lighting and power circuits seperate?
I would assume that in a chip shop there would even be a health and safety issue with having lighting and power on the same circuit in the event of an electrical fault plunging the cooking area into darkness.
The lights should be capable of staying on independent of any MCB/RCD protected power circuits.
What exactly is on this 32A ring anyway ?
Call up the NEC and have them re-inspect the work. Contractor's regulation bodies here can do that. They have regional inspectors who check that their members are doing things correctly.
Failing that write a letter to the property owner, stating your concerns. Take photographic evidence and discharge your duty of care.
Contact the HSE and see if you can get any advice / details of how they would suggest that you proceed.
