if i have a rec come out and add new lights and i already have preexisting lights on mcbs protected by a rcd can i have a new mcb fitted for the lights or will the rec have to add a deicated rcbo for the new lights under the new regs?

At 4 min they discuss the new rules on lighting;

- Rcd protection for all domestic lighting circuits

- Dedicated Rcd protection for bathrooms no longer required

-Faults must not cause a hazard therefore lighting RCBOs preferable

So what that's saying is ;

-You can add more lighting points to an existing circuit if suitable and is RCD protected

-You can add a new final circuit using a new MCB from an existing RCD

-the above musn't create a hazard

-Or add a new RCBO for the new lighting points

Perfect that's my question answered, thanks

Anything except lighting RCBOs will create a hazard imo

Not sure why the rules are relaxed on bathroom RCBOs and allowing shared RCDs if that the finished regulations
