"... and he was from Atos or something?"
It's been known that the gobshites that the BBC employ to check on addresses that don't pay TV licenses do stuff like what's been described. If there's no TV in the property, you don't need a TV license. They ask to come in and check, but without a warrant (which they won't get) they don't have to go in to your property. You can refuse them entry.
But when you do that, they decide to intimidate you by doing what the OP described. Imagine now you're a woman on your own or elderly and you see some jackass outside your house doing that?
