What can we do with this?

I know! How amazing. There are 276 known types of British bees though most of them are the solitary type (the ones that don't live in colonies).
When my children were small, we recorded bees for several years on a bee chart. They were always excited if they found a variety they hadn't seen before.

I didn’t realise there are so many different bees.

Red tailed bumblebees (and indeed other bumbles) don’t try to over-winter in colonies.

Have a look here now and you can find out more about these useful little bees:

If you find a beekeeper from your local beekeeper’s association they will be able to advise what the bees are and remove them to a new home.

Not Spaghetti thank you for the link. From the pictures, we think they are red tailed bumble bees.

cam you not spare them that little bit of allotment space? Bees are important and they are in decline in the wild. I had a compost heap in the garden that had a bee colony in it. They did no harm and we live together happily for many years until the colony died out, no idea why. Treat yourself to a posh new bin and just ley the other one bee (see what I did there?)

Contact a bee keeper. I can understand the frustration of being unable to get going with your allotment whilst being in such close proximity to a bee hive.
I am sure there will be a safe way to move them. The beekeeper will smoke them to quieten them and then take them away.

I had the same problem with one of my compost bins.
I contacted my next door neighbour who, at the time, kept bees , she came to collect them.
She told me later that they were not the usual honey bees as they were smaller , but nevertheless they produced an amazing amount of honey!
Why not keep the round bin anyway and have a second square one?
The bees may well move on next spring and you will probably find that one compost bin isn't enough!

Basically wild bees are just bees that have set up on their own and are not being farmed by a beekeeper. They are also called feral bees since many colonies are thought to have “escaped” from being kept when they swarmed.

No difference really.

I am getting confused about what type of bees they are.

Any chance you can just live with them?

They’ll be very good for pollinating your veg?

ExD - honey bees may or may not be “wild”.
There are other bees of course, but basically, honey bees are honey bees.

NotSpaghetti We think they are wild bees.

What type of bees are they?

Ask on your local FB groups etc for a beekeeper. If they are honey bees they can be collected and moved to a hive .

Any chance of a photo of one of them?
If they are wild bees I believe they behave rather differently from the bees beekeepers look after. I think some die off in winter leaving only the Queen to carry on next year - but I'm not sure.
(those compost bins make excellent compost though - I'd keep it).
