My solution is to not fly in that area
Otherwise, I would pass N of Stapleford at 1400 ft, well outside their ATZ and keeping a very good lookout (an awful lot of UK GA flies at 1000-1500ft) and getting out of there really fast.
I wouldn't recommend that TBH. That would put you slap bang in the middle of North Weald. It doesn't have an ATZ but can get extremely busy. Especially if you end up meeting one of the many formations that fly in and out, or some of the many jets based there might be operating that day. And don't forget the circuit height is 1100ft, so you'd only be a maximum of 400ft above it. At Stapleford, you could in theory be 1300ft above circuit traffic.
Overfly Stapleford and keep a listening watch on the radio. Much safer.
