The best grammar schools in London sit across three main routes: Sutton, Kingston and Bexley. London-accessible super-selectives include Queen Elizabeth’s School, Barnet and The Henrietta Barnett School, while Kent, Buckinghamshire and parts of Essex are realistic commuter options for some families. The best school is not simply the one with the highest results, but the one where a child has a realistic chance of entry and is likely to thrive.
Why “Best” Needs Careful Definition
The question of which grammar schools are the best in London is one that many families ask early in the 11 Plus process. It is a reasonable starting point, because parents naturally want to understand which schools combine strong academic outcomes, excellent reputations and a learning environment where children can flourish.
The better question, however, is slightly different: which grammar schools are the best fit for your child?
The most highly regarded schools are usually also the most competitive. They differ in admissions criteria, school culture, pace, pastoral support and the kind of pupil who tends to thrive there. Understanding those differences allows families to make much stronger decisions than simply chasing the most famous names. How many schools should we apply to for the 11 Plus? provides useful further reference when families are building a realistic shortlist.
Overview Of Top Grammar-School Routes In And Around London
Strictly speaking, there are relatively few fully selective grammar schools within Greater London itself. However, there are several major selective groups in London and around its commuter belt that families commonly think of as London grammar routes.
GOV.UK grammar schools provide the national context for grammar-school admissions, although each school and consortium sets its own admissions arrangements within the wider statutory framework.
Major Grammar-School Groups In And Around London
| Group | Location | Entry test | Selection method | Notes |
| Sutton grammar schools | South-west London | SET / second-stage testing | Score plus admissions criteria | Five major grammar routes |
| Tiffin schools | Kingston | Two-stage selective process | Score plus distance criteria | Highly competitive |
| Bexley grammars | South-east London | Bexley selective test | Score plus catchment or priority criteria | Four grammar routes |
| Barnet super-selectives | North London | School-set papers | Highly score-led | Among the most competitive nationally |
| Kent Test schools | Kent commuter belt | Kent Test | Score plus priority or location | The Dartford and Gravesend routes are popular with London families |
| Buckinghamshire grammars | Buckinghamshire commuter belt | Buckinghamshire 11 Plus | Score plus catchment or priority | Thirteen grammar schools |
Sutton Grammar Schools
The Sutton grammar school route is one of the strongest selective clusters nationally. The group includes Sutton Grammar School, Wilson’s School, Wallington County Grammar School, Wallington High School for Girls and Nonsuch High School for Girls.
Sutton Education Trust provides information on the shared Sutton testing route. These schools attract applicants from well beyond the immediate boroughs, and competition is intense because the academic outcomes are strong and the schools remain accessible to many south London and Surrey families.
The Sutton route is particularly important because it combines high academic selectivity with a wider regional draw. Families should not assume that proximity alone makes entry straightforward.
Kingston Grammar Schools
Kingston’s grammar routes centre around Tiffin School and The Tiffin Girls’ School. Both are academically outstanding and extremely competitive, with substantial applicant numbers and demanding assessment processes.
The Tiffin schools are often considered alongside leading independent schools because of their strong academic profile. However, admissions criteria, distance rules and the two-stage process matter greatly, so families should look carefully at the exact admissions arrangements before assuming either school is a realistic target.
Bexley Grammar Schools
Bexley remains one of London’s best-known grammar pathways and offers multiple selective options for families in south-east London. The route is particularly important for families who want a selective state-school pathway without relying solely on the very narrow super-selective routes.
Bexley schools can offer strong academic environments, but catchment and admissions criteria still matter. As with all grammar routes, passing the test and securing a place are not always the same thing.
Barnet Super-Selectives
Queen Elizabeth’s School, Barnet and The Henrietta Barnett School are widely regarded as among the most academically selective state schools in the country. These are true super-selectives, and competition is national in character.
Performance expectations are exceptionally high. These schools may suit pupils who are consistently at the very top of their cohort, naturally fast, highly accurate and resilient under pressure.
Because the competition is so fierce, families should avoid building an entire strategy around one super-selective school. Grammar school admissions may be useful for understanding how score, distance, catchment and oversubscription can affect outcomes.
Kent And Buckinghamshire Commuter Routes
Commuter-belt grammars remain strategically important for some London families. Kent routes may be realistic for parts of south-east London, while Buckinghamshire routes can be relevant for families in west and north-west London corridors.
These schools significantly broaden strategic options, but travel must be considered honestly. A school may look attractive on paper, yet a difficult daily commute can make it much less suitable in practice.
What Makes A Grammar School Highly Regarded?
A school’s reputation is shaped by more than one headline metric. Government school performance data is the strongest official source for comparing outcomes, and parents should look at GCSE Grade 7+ percentages, A-level A/A* outcomes, Progress 8, sixth-form retention, subject breadth and destinations.
Ofsted inspection outcomes also matter because they give insight into leadership, safeguarding, teaching quality and wider school culture.
The Good Schools Guide often provides useful parent-centred insight that raw data cannot, while Tatler Schools Guide can give an additional cultural lens for families comparing reputation, atmosphere and school character.
Taken together, these factors create a much fuller picture than results alone.
Looking Beyond League Tables
League tables are useful, but incomplete. They help identify academically exceptional schools, but they do not tell families how pressured the environment feels, how strong pastoral support is, how broad the co-curricular programme is, how well schools support transition into sixth form or how collaborative the pupil culture feels.
Two schools with similar academic results may feel entirely different in lived experience. One may be intensely exam-driven, while another may combine academic rigour with a broader, more balanced culture.
That difference matters enormously. Open evenings, school visits and conversations with current families are often more revealing than rankings. How to choose the right school for your child provides further reference for families comparing fit and outcomes.
Differences Between Grammar Schools
Differences between grammar schools are often sharper than parents initially realise. Some schools are effectively score-dominant super-selectives, while others combine a qualifying score with catchment, priority area, sibling criteria, distance tie-breaks or score banding.
The School Admissions Code provides the statutory admissions context, but individual school criteria vary. This matters strategically because a child may academically qualify for a school but still not secure a place if distance or priority criteria become decisive.
This is why admissions mechanics matter just as much as raw scores. How catchment areas affect the 11 Plus is especially relevant to families comparing the London, Kent, Buckinghamshire, and Essex routes.
Choosing The Right Grammar School
Choosing between grammar schools requires both academic realism and practical judgement. Super-selective profiles often suit children who are consistently at the very top of their cohort, exceptionally strong under pressure, highly resilient, naturally fast and accurate, and comfortable with fierce competition.
Local grammar profiles may suit strong all-round children whose scores, geography and admissions criteria create a more realistic route. These schools can be excellent options, especially where the daily commute is reasonable and the school culture fits the child well.
Families should also consider travel time, daily routine, pastoral support, breadth of extracurriculars, sixth-form pathways, and how well the child is likely to fit into the environment. The best grammar school on paper is not always the best grammar school for a particular child.
Match culture to the child, not just the results. That is usually where the strongest long-term decisions are made.

FAQ’S
-
Are there grammar schools inside Greater London?
Yes. Grammar routes exist across Sutton, Kingston, Bexley, Barnet and other London-accessible areas, alongside commuter-distance options in Kent, Buckinghamshire and parts of Essex.
-
How are grammar schools ranked?
Parents typically compare GCSE Grade 7+ rates, A-level A/A* outcomes, Progress 8 scores, Ofsted inspection outcomes and destination data. GOV.UK school performance data is the best official starting point.
-
Which is the hardest grammar school to get into?
Super-selectives such as Queen Elizabeth’s School, Barnet, The Henrietta Barnett School and The Tiffin Girls’ School are among the most competitive because they attract exceptionally strong applicants and offer limited catchment protection.
-
Do London grammar schools have catchment areas?
Many do, although rules vary significantly. Sutton, Bexley and many commuter grammars often combine a qualifying score with admissions criteria such as distance or priority area. Barnet super-selectives are much more score-led.
-
Can my child apply to multiple grammar-school groups?
Yes, but separate registrations are often required, and test calendars can overlap. Planning early matters because each consortium or school may have its own deadlines, formats, and admissions processes.
