Malcolm, I first got into bees by a swarm in my own chimney 20 years ago.
After some major discouragement from an experianced beekeeper, I forged ahead.
The entire excercise was a toatal disaster, but it got me hooked. They were
well established when I noticed them and I sent any number plummeting two
stories inside the chimney with their comb. They didn't recover at all well.
In the U.S. there is sold a spark arrester/hood for standard chimney sizes.
There is a expanded metal grill that might prohibit/reduce bee access.
I think they might discourage future swarms if they are available to you.
