I'm back with an update: I obtained a County Court Judgement against British Gas. They paid up. My claim was for negligence and breach of duty of care after they tried to bully me into a smart meter with illegal and unlawful practices. They said they were coming to my house to install a carcinogenic smart meter and if I wasn't in they'd fine me! Outrageous criminal conduct. They put their aptly named law firm Womble (as in The Wombles) on the case, but they didn't bother to defend the claim and so I won. I urge others to sue via small claims court, it's easy, it's a paper exercise.
