School Catchment Areas Have Changed: How to Check If Your Address Still Qualifies Before September

Imagine your child has been happily attending their primary school for two years, and you have not moved house. Then, in July, you discover the local authority quietly redrawn the catchment boundary last autumn — and your street is now on the wrong side of it. It sounds unlikely, but it happens every year across England and Wales as councils adjust boundaries to manage demand. With September just weeks away, now is exactly the right moment to run a school catchment area check for 2026 and confirm your address still qualifies.

This guide explains why boundaries shift, how to verify your eligibility quickly, and what to do if you discover your address no longer falls inside the catchment you are counting on.

Local authorities in England and Wales are required to consult on significant changes to admission arrangements, including catchment boundaries, under the School Admissions Code (England, 2014, last revised 2021) and the School Admissions Code for Wales. However, the consultation requirements apply to formal changes; smaller technical adjustments to mapping data or street-level definitions can happen with less fanfare.

Common triggers for a school catchment boundary update include new housing developments bringing more children into an area, a school expanding or reducing its published admission number (PAN), or a new school opening nearby that takes pressure off an existing catchment. Authorities must publish their determined arrangements by 28 February each year, but many parents only look at these documents when they are actively applying — not after a place has already been offered.

There are several ways to run a reliable check on school catchment address eligibility before September. The most authoritative source is always your local authority's admissions portal, which should publish current catchment maps or offer a postcode look-up tool. If you are in England, you can also cross-reference this with the school's own published admission arrangements for the 2026–27 academic year, which must be made available on the school's website.

School Atlas's admissions calculator lets you enter your postcode and see distance-based and catchment eligibility information for schools near you, drawing on up-to-date local authority data. This is a useful starting point, particularly if you want to compare several schools at once or understand how your address ranks against typical cut-off distances from previous years.

While both nations use catchment areas as an oversubscription criterion, the legal frameworks and local practices differ. In England, the School Admissions Code (2014, last revised 2021) sets out the rules governing how admission authorities must define and apply catchment areas. In Wales, the School Admissions Code for Wales applies, and Welsh local authorities have traditionally operated with somewhat wider discretion in how catchment boundaries are drawn and communicated to parents.

One practical difference is that Wales does not use Education, Health and Care (EHC) plans — children with additional learning needs in Wales have Individual Development Plans (IDPs) under the Additional Learning Needs and Education Tribunal (Wales) Act 2018. If your child's place is linked to a specialist provision attached to a particular catchment school, it is worth checking whether any boundary changes affect that arrangement specifically.

Discovering that your address no longer sits inside a catchment boundary is stressful, but it is not necessarily the end of the road. If your child already holds a place at the school, a boundary change does not affect their continued enrolment — places are not withdrawn retrospectively because of boundary adjustments. If, however, you were planning to apply for a place based on that catchment (for example, a new school year, a sibling application, or an in-year transfer), you will need to act quickly.

Your options typically include: joining the school's waiting list, which in England must remain open until at least 31 December of the year of admission for the normal admissions round (School Admissions Code, para 2.14); lodging a formal appeal with the school's independent appeal panel; or exploring alternative schools where your address does fall within catchment. Our guide to school admissions appeals walks through the process in detail, and our catchment areas and transport guide covers what happens when the nearest school is not your catchment school.

A change of home address is one of the most common reasons families find themselves unexpectedly outside a catchment. If you have moved since your child's place was originally offered, you should notify your local authority and the school as soon as possible. In England, admission authorities are permitted to withdraw a place that was offered on the basis of a fraudulent or intentionally misleading address — but a genuine house move is treated differently, and you should inform them proactively rather than waiting to be asked.

If your new address falls outside the catchment of your child's current school but your child is already enrolled, the school cannot generally force a transfer. However, if you are mid-application or your child has not yet started, the new address is the one that counts for catchment purposes. Use the admissions calculator to see which schools your new address makes you eligible for.

With September approaching and school places filling up, the time to verify your catchment area eligibility for September 2026 is right now — not after term starts. Use the tools and guides below to check your position, understand your options, and plan your next move with confidence.

You can explore schools in your area using School Atlas Explore, check admission probabilities with the admissions calculator, or find a school that suits your child's needs with the school matcher. If you need broader admissions guidance, our full guide library covers everything from appeals to faith school criteria.
