1% for spend under 10k, 1.25% beyond on the Amex Platinum Cashback Credit Card. Combine that with the fact that Amex gives targetted cashback offers I can well believe you can end up averaging several percent on a yearly basis if you're taking up some of the higher value ones (I currently have an offer for £100 cashback for £1000+ spend at Trailfinders, that would bump my average cashback up a fair bit!).
