Moving House for a Grammar School Place: How Catchment and Distance Rules Really Work
Passing the 11+ is only half the job. In most areas, whether an offer follows depends on where your child lives — and "catchment" turns out to mean four quite different things depending on the school. Families move for a grammar place, sometimes at real expense, and then discover the measurement runs down a different road, or the address that counted was the one from six months earlier. This guide sets out how proximity rules actually work, how addresses are measured and checked, and what to confirm before you commit to a move.
The four models of proximity rule
Before you move:
- Read the exact admissions arrangements for your specific target school — the model, and the measurement method, vary school by school.
- Measure the straight-line distance from the address you're considering to the school yourself, and compare it with three years of "last distance offered".
- Make sure you'll be genuinely, permanently living at the address by the application closing date — 31 October 2026 for 2027 entry.
"Catchment" is not one thing
The word covers four different mechanisms, and which one applies decides whether a move is worth considering:
- A designated or priority area is a named geographic zone. Qualifying children who live inside it are placed in a higher priority group than qualifying children outside it. A move into the zone can genuinely change the outcome — but only if your child also clears the test threshold.
- Distance only means there is no zone at all. Every qualifying child is ranked, and where scores tie, the child living closer to the school wins. Here, a few hundred metres can matter — but only at the margin.
- Super-selective, national schools rank almost entirely by score. Distance is a final tie-break between identical scores, so moving closer rarely changes anything.
- A hard boundary means only children living inside a defined area are eligible for a place at all, regardless of score. A move is then essential, not optional — and moving out later can cost the place.
How distance is actually measured
Most local authorities measure a straight line ("as the crow flies") between a fixed point at the home address and a fixed point at the school, using the council's official address and mapping database. A minority measure the shortest available walking route instead. The two can give very different answers on the same street.
- The point used at your address is defined by the council's database, not by your front door — a block of flats may be measured from a single shared point.
- The point used at the school is also fixed (a main entrance, or a central point), so "nearest gate" reasoning doesn't apply.
- Because the method is fixed and applied identically to everyone, you can estimate your own position reasonably well with an online straight-line tool — then sense-check it against the school's published "last distance offered" for recent years.
Which address counts, and when
The address that matters is where the child normally lives — the majority of the school week — on the closing date for applications (31 October 2026 for 2027 entry). Not where you intend to live, and not where you lived when you registered for the test.
- Moving after the closing date generally does not change your priority for that round. If a place is offered on the basis of an address you've since left, the local authority can withdraw it.
- Short-term or nominal tenancies taken out to gain an address — while keeping a property elsewhere — are treated as address fraud. Local authorities investigate, ask for evidence (council tax, tenancy, utility bills, GP registration), and withdraw places where they find the family did not genuinely relocate.
- Owning a second property near the school while your family home is elsewhere does not usually count; the family home does.
- Separated parents are normally assessed on the address where the child spends the majority of the school week; some authorities have specific rules for shared care.
Before you commit to a move
- Confirm the school's model. Designated area, distance-only, national, or hard boundary — the school's admissions arrangements say which, and it changes whether a move helps at all.
- Confirm the measurement method — straight line or walking route — and the points used.
- Check historical data. Most schools publish the last distance offered, or the boundary of places offered, for the past three years. Trends matter more than a single year.
- Time the move properly. Be genuinely resident at the new address, with evidence, well before 31 October 2026.
- Have a fallback. A move plus a strong score is still not a guarantee at an oversubscribed school. Keep a realistic alternative on your application.

Frequently asked questions
Does moving house help you get a grammar school place?
It depends entirely on the school's admissions model. For a school with a designated or priority area, moving into the zone can genuinely improve your priority. For a distance-only school it helps only at the margin, on tie-breaks. For a national super-selective it rarely matters. And for a school with a hard geographic boundary, the right address is essential regardless of score.
How is distance to a grammar school measured?
Most local authorities use a straight-line ("as the crow flies") measurement between a fixed point at the home address and a fixed point at the school, taken from the council's official address and mapping database. A minority use the shortest available walking route instead. The method is set by each authority and applied identically to every applicant.
Which address is used for a grammar school application?
The address where the child normally lives for the majority of the school week on the application closing date — 31 October 2026 for 2027 entry. Not the address you plan to move to, and not the one you used when registering for the test. Moving after the closing date generally does not change your priority for that round.
Can a grammar school place be withdrawn for a false address?
Yes. Local authorities investigate suspected address fraud — for example a short-term tenancy near the school while the family home stays elsewhere — and ask for evidence such as council tax, tenancy agreements, utility bills and GP registration. Where they find the family did not genuinely relocate, they can and do withdraw the offer.
What is a designated area for a grammar school?
A named geographic zone defined in the school's admissions arrangements. Qualifying children who live inside it are placed in a higher priority group than qualifying children who live outside it. It is different from a distance tie-break, and different again from a hard boundary that makes out-of-area children ineligible altogether.
How do I find a specific grammar school's catchment rule?
Read that school's own determined admissions arrangements, published on its website and on the local authority's admissions pages. They state the proximity model, the measurement method and the oversubscription criteria, and most schools also publish the last distance offered or the area of places offered for recent years.
