Thanks for all the comments and advise, highly appreaciated. Ianr, well spotted, Avondale Rise. Many thanks for taking the time to have a look at the area: "I've been to have a look. In that segment of Avondale, apart from double yellows and bus stops, there are three small residents' parking bays. They're all in the half nearer to Copleston and so apparently in the Peckham W zone. Each has a sign saying Residents Parking Only 0900-1100, which tallies with what we agree are the times applying in Peckham W. After that I went back to the website and added the Peckham W and DKH zones in turn, just to check that I had the right ones. Which, I'm afraid, seems all to be consistent with your having parked in the Peckham W zone. But I'll be happy to be told I've got it wrong." Our car was parked between the double Yellow lines and the bus stop (single yellow line there, no parking bay with clear restriction times), according to the cpz map on the DKH cpz side of the railway (even if there are no signs dividing the 2 cpz areas as Southwark council claims)
