School Radius Planning When Moving House
A radius around a school turns an overwhelming map into a focused search. Used well, it saves time; misunderstood, it gives false confidence. Here is how to plan with one properly.
Last reviewed:
When a particular school is driving your move, it helps to draw a line around how far out you are willing to live. That is all a search radius is: a planning boundary that keeps your house-hunting focused and consistent. The skill is in choosing it well and knowing its limits.
Why a radius helps
Without a boundary, it is easy to drift — viewing homes that are really too far, or dismissing areas you have not measured. A radius gives every candidate home the same test: inside the circle is worth considering, outside is a deliberate exception. Visualise one for any school with the School Radius Map.
Choosing the right radius
Set the radius to the furthest distance you would genuinely accept for the daily journey, then work inwards. Consider how you will travel — a three-mile walk is very different from a three-mile drive on congested roads. Pair the radius with the Commute Cost Calculator so the boundary reflects time and money, not just distance.
What a radius cannot tell you
A radius is a circle; a catchment is not. Real catchments follow roads, rivers and historic boundaries, and they move year to year with demand. A home inside your radius may sit outside the catchment, and a home at the edge may still be too far in a heavily oversubscribed year. Read catchment area vs distance to see why the two diverge.
Turn the radius into a shortlist
Once your radius is set, list the homes and areas inside it, then check each against the things that actually decide the move — distance, commute and budget. For selective schools, our guide to areas near grammar schools shows how to apply this without falling for league-table shortcuts.
What to verify before you rely on a radius
- The school's designated catchment, which will not be circular.
- How the authority measures distance — straight line or walking route.
- Recent cut-off distances, as a rough indication only.
- The real journey time and cost across your radius, not just the miles.
- Admissions deadlines that affect when you need to move.
A radius focuses a search; it does not award places
Frequently asked questions
What radius should I search within?
It depends on the phase and how you will travel. For primary schools a 1–3 mile radius suits a walk; for secondary or selective schools, 5–10 miles is more realistic. Set the radius to the furthest you would genuinely accept, then narrow down.
Is a radius the same as a catchment?
No. A radius is a circle you choose to focus your search. A catchment is a specific boundary set by the school or local authority, which is rarely circular and can change each year.
Can a radius tell me if I'll get a place?
No. A radius only helps you decide where to look. Admissions depend on the school's criteria and the applicants in a given year, so you must verify the policy and recent cut-off distances directly.
