This register is now up and running. This came about because of Lord Young's report which suggested that individual consultants were to blame for the silly stuff like banning conkers whereas really the compensation culture needs to be addressed first. However, people who have chartered status as a health and safety consultant (like me) can now register. Eventaully, the public will be able to access this register.
Trade associations don't have to register and, one supposes that Lord Young decided they were quite able to select advisors who are suitably qualified.
The general consensus is that this register will have no effect.
