How this NestScope Score works.

We map what’s nearby. Schools, safety, healthcare, transport, green space and amenities around N21 3SA — each measured at its own radius, from a 0.25-mile crime count to a 2-mile school catchment.

We blend in national context. Every local factor is combined with England’s Index of Multiple Deprivation, so a postcode is judged both on what’s actually nearby and on how the wider neighbourhood compares nationally.

One score, six visible factors. Schools, Safety, Healthcare, Transport, Green space and Amenities each get their own 0–100 score; the six combine into the single NestScope Score above. No black box — see the full methodology.
