I doubt there are, or at least very often.
Of some of the London contracts in which I am involved - a local authority Town Hall roof, at a national construction firm base on the outskirts, a Church roof, a Hackney estate - only the Church and the estate have any idea.
The Church sell the honey locally to promote and help fund the
Lighthouse Project, a support centre for the homeless, the hungry and those in need of help; last year they served 25,000 meals. The estate sell the honey locally and run extraction events to raise awareness of food provenance, environmental issues and the like.
The other two are typical of the vague and fluffy desire of someone in authority to tick a box and feel good. The Town Hall CEO saw that Fortnum's had bees and saw no reason why his kingdom shouldn't have them. They hadn't and haven't a clue how to use the hives or the honey to promote anything, not even to tie them to existing policy to green the borough or educate; at a meeting to lay out the opportunities it became clear to us that they were out of their depth, and the honey remains in buckets while the wheels of decision turn incrementally slowly.
The construction company have no idea at all beyond a vague desire; with both of these we see an opportunity to educate and inform, because otherwise it is mere greenwashing that pays our bills.
On the other hand, The Golden Company in Shoreditch, near the City of London, was a creditable organisation
working to give local teenagers business skills from hive to market; I believe it no longer operates, but did experience its tangible success while loading the Land Rover one morning at home in Hackney. A young man walked past and his eyes lit up when he saw the boxes; Joseph had been a teenage trainee beekeeper and had since moved onto other things, but retained warmth for the project that had help guide him to the right road.
