As I am sure you are aware by now, legally you are allowed to check your bees as they are livestock. You should still take basic precautions and keep social distancing in mind.
I would advise as some local police forces have been quite strict in their interpretation that you carry your BBKA membership card with you when out.
Failing this you can print your receipt you would have got from me when you renewed this year or if you are still not happy I have created a Burton Beekeepers membership card which if you email me a passport photo of yourself, I can create and send it back for you to print.
If there are any issues with the police and they want proof then please ask them to contact me and I will confirm your membership status and location of your hives.
Secretary and membership officer
