It is true that information on gov web page is incorrect. It is a consequence of general incompetence of previous government in many areas.Maybe you should all start putting your efforts into taking down the ebike companies and the government for their mistakes instead of nitpicking at people like me for doing everything in their power to follow these asinine laws.
It is in your best interest to follow the law, not what is written on gov web page. Restricting power output to 250W would make all e-bikes virtually unusable.
