Buckinghamshire Council publishes an "Allocation Profile" after every National Offer Day, showing exactly which rule each school's last place was allocated under, and the distance that rule reached. The number only means "you needed to live this close" in years marked plain — those are genuine out-of-catchment Distance cut-offs; years marked c, s or p were decided by catchment, siblings, or an inner priority-area tier instead, so distance was never reached. It moves a lot year to year — sometimes by several miles — so treat any single year as a snapshot, not a guarantee. Historically, out-of-county appeals rarely succeed either: Chiltern Relocation, a local relocation agency, cites a 3% success rate for out-of-county grammar appeals in 2020 — the most recent figure we've found — so a property decision made on the assumption of winning an appeal is a risky one.

c = filled by catchment alone that year · s = decided by a sibling rule · p = decided by an inner priority-area tier · unmarked = a genuine out-of-catchment Distance cut-off.
Figures are Buckinghamshire Council's own published Allocation Profiles for each year's National Offer Day (1–3 March). A few schools (Aylesbury High, Sir Henry Floyd, Royal Grammar School) show wide swings because they draw qualified applicants from a very broad catchment-free or partly catchment-free pool — a single strong or weak year among nearby families can move the cut-off by several miles.
