TBH Camberwell Cars charged ?7 from my place to Kings, which is a slightly shorter journey than North Cross Road (Peckham postcode), so it's not much different. It's a lot of money, but consider how many jobs they do a day, how much it costs to run a car and pay for petrol, insurance, etc... and how much cut the agency will take... I don't think they're exactly coining it in.
