I go to the Golf Lab in Canary Wharf (v. similar to Urban Golf). £40 per month gives me 30 minutes per day in a simulator with cameras to record the swing and play it back, and as many balls as I want to hit, plus a 30 minute lesson once a month.
It's made a vast difference to my game. It's similar to going to the driving range, but it's far more convenient for me. Plus the instant feedback from watching your swing back is invaluable (at least in my experience).
I've been cut 3 shots in 3 months, and have been playing more consistent overall.
