In recent weeks when I have been passing Ovingham, 15 miles away, I have stopped several times to see the bees in the wall, both Andrena scotica and Nomada marshamella. Now the bees have come to see me. In recent days I have found at least a dozen bees inside the dining room on the French windows. I think they come in when the doors are open as they explore holes in the wall outside but I also think they are living in the wall of the house so it is possible they are getting in from the inside. All those I have seen are female Andrena scotica, or chocolate mining bees.
Two bees were dead before I found them. Here are a couple of a close-ups of the scopa, the pollen brush on the bees' hind legs, showing the characteristic black and white hairs. Although they are a bit dusty they show no pollen grains so I think these bees had not started foraging.
The good news for these bees is that I haven't seen their cuckoo bee, Nomada marshamella, so far.
