Dear travellers
The allowance at LHR T5 to use fast track is as follows (did summarize it from the replies):
1) Fast Track Immigration: Not for EEA+Swiss travellers, not for Registered Travellers (there might be exceptions) and not for UK oversea Citizens. EEA children join their Non-EEA parents in this channel*.
Required: OW Saph/EC Silver and above; Club/First.
2) Fast track "passport-check" for international connecting flights (before going up the escalator to security check): Club/First, OW Saph/EC Silver and above*.
3) Fast track security: Club/First, OW Saph/EC Silver and above, Invitational guests*.
4) E-Passport machine immigration: For EEA+Swiss travellers and UK oversea citizens, at age 18 or older with a biometric passport; manual route (using non-biometric passport) available. Use of this route is independent of travelling class*.
5) Do-It-Yourself-Fast-Track (use 4 instead of 2):

6) Separate "Express line" available in T5 for tight international connections*.
