As far as I'm aware - at the present time neither police nor hems operation units require an IR.
Although the 11 pilots within the Met ASU have all recently completed their IRs.
There was a job advertisement recently to recruit an additional Met pilot and one of the requirements was for the candidate to have an IR.
It's guess it's only a matter of time before other forces follow suit. As for the Hems units I don't know?
