As an outsider, surely the spirit of the competition law was to increase competition and stop people acting in union and therefore artificially creating a fixed price.This is what BUPA are doing. It will be worse when the other insurers join in. It results in far less competition. It seems like a case for getting all health providers together to fund a campaign to change the law. Or at least point out that the law is limiting competition rather than increasing it. Can you get the opthalmologists, the radiologists etc talking about it? If there was a BUPA for barristers it would change tomorrow.
Also who owns BUPA. Share holders? Can they be spoken to by individuals?
