It depends on the type of bees in his roof space. If it's bumbles just leave them alone, if it's honey bees it's advisable to get them moved as honey and wax in your roof isn't the greatest of ideas especially if the colony dies out!

I've sent him a link to the local beekeepers website.

What's your opinion on bees nesting in the wall of a house? Was a while ago that I looked at the house, so it may not be a relevant question any more.

again it depends on the sort of bee.solitary ones and small colony ones are ok unless the holes they are using are breaching your water seal and need fixing to cure your dampness,big colony ones like honey bees can be a problem but are unlikely to pick a wall as the spaces are usually too small to be much use to them.

very defensive africanised ones could be a bit upsetting should they ever get to yorkshire and move in.

Looked like honey bees to me. I was surprised that they'd found room.
My thought was that they would rapidly run out of room and swarm, so it would be a good idea to have a bait hive handy.
I don't suppose anyone there listened to me though.

Coming back a point though: what problems would they cause?
Will they be digging out the loose mortar? I'd've thought they'd be more sticking the place back together, albeit with wax...

Bees are the symptom not the cause of loose mortar.
i.e. if the bees can burrow in, then the mortar is perished and needs repointing anyway.

defending their nest can have issues,depending on the culture of the hive they can claim anything from a few feet to quite a few metres.if their defended area includes paths,garden etc there can be a conflict of interest.

Old stone walls: it was the mortar inside the wall I was thinking of.
And I wasn't suggesting that they made the mortar loose, but to my mind loose mortar is better than a hole...

The entrance was high up on the wall and I don't think the window nearby opens.

I think they nearly all use magic poles these days.

Yeh bees making holes in your mortar isn't good, but if the mortar is as weak as an earth bank (the bees equivalent natural home) then you've likely got other problems and further degradation will still occur without help from the bees.

Bees will take up residence in cavity walls, which are pretty common round here because we have a lot of brick built, double skin with cavity houses. Beekeepers can't do anything, so if you want to get rid of them I am afraid it is a case of killing them, so we usually advise living with them. If it is a solid stone wall, or rubble filled, I don't think they are likely to be honey bees, as they prefer a hole to nest in.

I will freely admit that I am not an expert, but the nearby window gave a pretty good view and they looked very much like honey bees to me.

If you have a large honey bee colony in your building & they die out or get poisoned any uncapped stores left will ferment & grow mould.
Which can cause localised mould spots on ceilings & plasterboard walls.
When a colony is thriving they pose little risk.
Pest control firms are happy to spray insecticide. But I've never heard of any that will take down a ceiling & remove all traces of occupancy. If they don't the above issue could be a problem although usually the smell of brood comb just attracts another swarm to the spot.
