That being said, the UK is screwed. Police not having firearms, civilians largely unarmed and a huge population density probably made it a zombie buffet. At least England.

England's got the Royal Guard right? They're all armed with weapons. Perhaps there is a group of survivors lead by members of that esteemed group. They are trained to be super serious and focused (and humorless), especially the ones guarding the Palace.
