I currently live in Peckham Rye (catchment for Belham) and have been considering moving to Brockley Conservation Area for more space but am concerned that I would be giving up almost definite entry to great schools (Belham then East/North Dulwich Charter) for a much riskier situation as the area I'm looking at seems to be right on the edge of a lot of primary catchments (Ashmead, Gordonbrock, Prendergast, etc) but not actually in any. Similarly I'm not sure about the secondaries in Lewisham Vs Southwark. We preferred Telegraph Hill but there isn't much coming up and in any case price differential with where we are now isn't big enough to make the move worthwhile. Does anyone have any advice or experience with a similar move?
