A school catchment area is the geographic zone around a UK state school inside which children are usually offered a place. This guide explains how catchment areas are set, how distance is measured, what they mean for your chances of a school place, and includes a free postcode tool so you can check any address in seconds.
Enter a UK postcode, plot the school on an interactive map, and find out instantly whether your address falls inside the catchment zone.
A school catchment area in England, Wales, Scotland and Northern Ireland is the area within which children are normally offered a place at a given state school. In most of the UK there is no fixed boundary marked on a map — instead, your Local Authority publishes the furthest distance at which an offer was made in the most recent admissions round. That distance, drawn as a circle around the school, is the effective catchment area for that year.
Catchment areas only really matter when a school is oversubscribed. If a school has more places than applicants, every child who lives near enough to count it as a reasonable journey will be offered a place regardless of distance.
There are two fundamentally different types of school catchment area in the UK: distance-based catchments (used by most English local authorities) and defined boundary catchments (used by Sheffield, Solihull, much of Scotland, and a growing number of academies and faith schools). It matters which kind your school uses, because the way you check — and your chances of a place — are completely different.
Most councils use straight-line (“as the crow flies”) distance from a fixed point on your property to a fixed point at the school. A small number of authorities use shortest walking distance instead — always check your council's policy.
Some councils don't use distance at all. Instead they publish a fixed geographic catchment — a polygon on a map, a list of named streets, or a designated “associated area.” If your home is inside the zone you get catchment priority; if it's outside, you don't — no matter how close you live. Examples include Sheffield, Solihull (full borough polygon catchments), most of Scotland (delineated catchment areas), and many academies and faith schools that publish their own boundary maps. Always check whether your school uses a distance or a boundary rule.
For distance-based schools, the catchment area for any given year is the furthest distance at which an offer was made on National Offer Day. Local Authorities publish this for every oversubscribed school — it is the best single indicator of your chances.
The school end of the measurement is usually the main entrance, the school office, or the centre of the school building — different councils use different conventions. Check the published admissions policy before relying on any distance.
Catchment distance is recalculated each admissions round. A property that was comfortably in catchment last year can be outside it this year if a cluster of new applicants live closer to the school.
The fastest way to check is to use our free school catchment area checker. It plots any UK school on an interactive map, draws the catchment radius, and tells you whether any postcode or address is inside.
Click Open Free Tool to launch the interactive map.
Search by school name or postcode — the tool will plot it on the map. You can add up to five schools to compare side by side.
Look up the most recent last distance offered from your council's admissions statistics, then enter it as the catchment radius.
Type a postcode or full address into the "Check Address" box to see instantly whether it sits inside the school's catchment area.
Primary and secondary school catchment areas behave differently, and it pays to understand the difference before you commit to a property move.
Primary catchments are usually much tighter — in dense urban areas, the catchment for a sought-after primary can be under 300 m. Parents typically need to be very close to be confident. Primary school catchment checker ›
Secondary catchments are broader because secondary schools draw from a wider area, but the most oversubscribed grammar and faith schools can still have catchments of well under a mile. Secondary school catchment checker ›
No. Catchment is one of several oversubscription criteria, and it is normally near the bottom of the list. A typical priority order for a community school is:
Faith schools, grammar schools and academies often use additional criteria before distance is considered. Always read the school's specific oversubscription criteria — they are published every year in the school's admissions policy.
Properties inside the catchment for a high-performing UK state school typically sell for a measurable premium — research by the Department for Education and several estate agency studies has put the figure at around 20%, and significantly more for the most sought-after grammar and outstanding-rated schools. Be cautious before paying that premium: catchment areas shift every year, and a property that is "in catchment" today can fall just outside next year if demand rises.
A school catchment area is the distance within which all applicants received offers at a UK state school in the most recent admissions round. It is set each year by the Local Authority based on where applicants live — there is usually no fixed boundary line.
Use our free school catchment area tool. Enter your postcode, plot the school, and add the catchment radius from the school's most recent admissions data. The tool tells you instantly whether your address is inside, outside, or near the boundary.
Most UK councils use straight-line distance from a fixed point at your home — usually the front door — to a fixed point at the school, typically the main entrance or the centre of the school building. A handful of councils use shortest walking distance instead.
No. While most English local authorities use distance, some councils — including Sheffield — and most of Scotland use a defined geographic boundary, sometimes called a delineated or associated catchment area. Many academies and faith schools also publish their own boundary maps. Inside the boundary you have catchment priority; outside, you do not, regardless of how close you live.
No. Last year's catchment distance is only a guide. Demand changes year-on-year — if more siblings or higher-priority applicants apply, the effective distance for everyone else shrinks. Always nominate more than one school on your application.
Local Authorities publish annual admissions statistics showing the furthest distance offered at each oversubscribed school on National Offer Day (1 March for secondary, 16 April for primary). Search for "[Your council] school admissions statistics" or check the school's own admissions policy document.
No — catchment areas in the UK are recalculated every admissions cycle. A house that was inside catchment last year can be outside this year if a few more applicants live closer. Always look at three to five years of historical catchment data, not just the most recent.
