I found a dead one under the nest and a quick search of the internet shows its a Tree Bumble Bee Bombus hypnorum. A recent newcomer to the UK (2001) that has spread northwards from the SE of England. Those half a dozen bees swarming round the nest are apparently protecting it and have "buzzed" Mrs Alf on a couple of occasions when she was gardening.
