Went to consultant in October, listened to me, understood and, from the evidence, diagnosed ADHD (mostly inattentive).
He listens, didn't mind I was an hour late (occupational hazard? And don't take this as proof he'll do it for you!), gave me advice on late night hyperfocus (internet timer, the one I've chosen I temperamental). Endlessly patient and not wed to any one treatment.
Apparently, a new clinic has opened in Manchester, but I recommend you see the Liverpool Specialist outpatient at Breightmet, he's an excellent person.
Edit: Not dissing the Manchester one, just have no experience with it.
