RoadChef, which operates one of the largest motorway services on the M25, has defended its decision to ramp up the price of overnight parking by 25%.
Overnighting at Clacket Lane Services between Junctions 5 and 6 now costs £25 (up from £20) - and drivers are not impressed.
One regular user says: "I think it's absolutely outrageous. It will tip people over the edge. One of the showers doesn't work properly and the park stinks. I didn't even know about the rise until I got there the other night - how the hell can they justify charging that?"
A RoadChef spokesman says the cost of overnight parking has not been reviewed for some time and drivers get money back because the price includes a meal voucher. "It's important to realise you get £10 back on goods," he says.
