Hang about... according to that map, I don't live in Forest Hill but I do most definitely have an SE23 postcode - and the Horniman Gardens don't count either?

Shouldn't surprise me though I guess since despite having the SE23 postcode, I pay council tax to Southwark, get East Dulwich police when there are problems and vote in the College Ward. I'm really mixed up when people ask me where I live!

My neighbours across the road might be miffed at being left out since they are Lewisham resident
