I spent a long time looking for a place for my bees, 'they have moved about a bit' you could say. The current situation is that they overwinter on my allotment where I can keep an eye and will go back to the derelict farm where they live in the summer.
I have had vandalism on the allotment, and have also upset another allotment holder a couple of years ago, when I had hives there in summer and whilst doing my inspection he and his family got stung. He is fine with me now, but I would only keep a colony there if I could be sure of their temperament.
Get your OS map out, and see if any one has a long garden they don't use. I understand that there is a website which connects people who want a garden allotment with those with spare land (why not bees). I think it is called 'Landshare', and is linked to channel 4.
