Naming of Chervil Way, and the extent of Great Burnet Close, might not be right.
I haven't yet found enough information on the ground to alter anything accurately, but from the address on the entrance board for Coton Park Play Area [1] some of what's currently mapped as Chervil Way[2] and Great Burnet Close[3] might actually be Begonia Way.

I also haven't surveyed [2] north of the location of this note, so there may already be new street nameplates north of here that can answer these questions for sure.
