Can anyone identify these bees we have found

cmcn

We have found this bees nest in a compost heap, can anyone tell us what they are.  They appear to be unaggressive.

I think if they're in your compost bin, they are a type of bumblebee (as opposed to honeybees), but which one, can't help, sorry.

This is a useful site to use to identify bees.

This might be a moss carder bee on account of the colour of the wings - see https://friendsoftheearth.uk/bee-count/great-british-bee-count-brown-carder-bees I am sorry but the other site listed above is not much use.
