I would think that there would be some sort of "fair use" for trademarks. My understanding is that the philosophy behind trademark law in the US is always based on whether or not a reasonable consumer would infer that the advertisement is officially associated with the trademark holder. But given that, I don't know why so many companies use the term "The Big Game" rather than "Superbowl"; maybe they like it better than having to explicitly include a disclaimed. And I also have no idea how the law works in the UK.
There is, it's called nominative use (in the US, but similar must exist overseas). Otherwise no-one would ever be able to refer to a trademark without being open to a lawsuit. That's how books about technologies with trademarked names can exist, for instance.
