Because the opening hours and geography were more convenient I used to use the tip in a neighbouring borough, but most local authorities have now erected import barriers and that's not been possible for a long time now.
A residents' parking permit used to be enough to get you in to ours, but as the parking permit scheme has gone paperless you now need to apply for a a special vehicle permit to visit the tip (joined up thinking there....)
My local tip also banned pedestrians for a while, but seems to have seen sense now.
