It's available to anyone with residence longer than 6 months in the UK. My IRIS registration will expire end of October this year [which is also the ending date of my current 4 year visa]. Of course, if I extend my stay I will be able to extend this too.
I use it mainly at BHX and sometimes at LHR and never had any problems. Actually, it seems to me that it's working faster nowadays. Once we diverted from BHX to MAN because of the snowstorm and went straight through there as well.
