Tony Travers suggests that part of Barnet's EasyCouncil model could mean that you pay a higher fee for a planning application in return for getting it prioritised for a quicker decision. I can see the analogy. As with a low cost airline you pay a bit extra if you want something more than the basic service – extra baggage, food and drink, early boarding.
Would this be acceptable? Some planning applications are more urgent than others. For instance a loft extension wanted as a new baby is on the way compared to a loft extension some time when there is enough money to pay for the builders as a bit more room would be nice.
I suppose some might resent "queue jumping" – although appreciate the lower Council Tax which extra revenue from fees might provide.
