traffic info
Do any controller give traffic info when two acft are cruising with one thousand feet apart and crossing behind/in front with less than 2nm?
Do pilots expect/prefer infomation like that?

There is a requirement stated in the Canadian Manual of ATC Operations to pass traffic information when aircraft will pass with the minimum vertical separation.

They don't in Europe.
In some UK sectors, to do so would double the ATC workload, which is already at maximum capacity,
On lots of the popular routes aircraft routinely pass directly over or under each other with 1000' separation without any mention of it by ATC. Why should they?

As others have already stated, there is no requirement in the UK, but CAP 493 (Manual of Air Traffic Services Part 1) does give some general guidance:-
"Under some circumstances, controllers may consider it prudent to inform a pilot of other traffic which is separated from his aircraft. In such cases, to prevent any possible confusion, no reference should be made to the actual level of the other aircraft. If necessary, the pilot should be informed that the other aircraft is (number) thousand feet above/below."

In the U.S., generally, yes.
FAA 7110.65
5-1-8. MERGING TARGET PROCEDURES
a. Except while they are established in a holding pattern, apply merging target procedures to all radar identified:
1. Aircraft at 10,000 feet and above.
2. Turbojet aircraft regardless of altitude.
REFERENCE-
P/CG Term- Turbojet Aircraft.
3. Presidential aircraft regardless of altitude.
b. Issue traffic information to those aircraft listed in subpara a whose targets appear likely to merge unless the aircraft are separated by more than the appropriate vertical separation minima.

At STN when on 05, I will advise the inbonds and outbounds of each other.
As the downwind track crosses the westbound SID routes. It can't hurt to cover all bases. Inbounds dropping to 6000 and depts climbing to 5000.
That's just my opinion.
