Choosing the pathway: American, British or IB
The first decision is which curriculum your child will study in London. Three pathways are available. The American pathway, primarily through the American School in London (ASL), preserves the US curriculum, AP courses and the US college application timeline; for families who expect to return to the US for university, it is the structurally easiest choice. The British pathway, through one of the large set of British independent schools, switches the family into IGCSEs and A-Levels; it is more demanding to enter mid-stream and typically delivers stronger results into UK and continental European universities. The IB pathway, through schools such as Southbank International, Marymount or ICS London, sits between the two and travels well to either UK or US universities.
Children below age 11 can usually switch between any of these pathways without lasting impact; primary curricula differ in pedagogy but converge on the same core skills by year 6. Children between 11 and 14 face more work in the transition but can absorb it with school and tutor support. Children above 14 are usually best advised to stay within their existing curriculum or to switch only to the IB, which retains American breadth more than A-Level does. Avoid moving an American 15-year-old into year 11 of a British school cold; the GCSE syllabus is a year of preparation behind them and the result is a stressful year with little upside.
Our curriculum overview pages set out the structural detail for each pathway, and the A-Level versus IB for UK universities piece compares outcomes once the choice narrows to those two routes.
The American School in London
ASL is the natural anchor for most New York families landing in London. The school sits in St John's Wood, runs K through 12 on a US calendar (August to June), and uses the US curriculum with AP courses in upper school. Around 75 per cent of leavers go to US universities, 15 per cent to UK universities, and the balance to continental Europe. The school is academically strong without the intensity of the most selective Manhattan independents; many New York families find the move to ASL is a measurable reduction in academic pressure for their child.
Admissions at ASL are competitive in the popular year groups (kindergarten, year 6 transition to middle school, year 9 transition to upper school) but less competitive in off-cycle entry points. The school assesses through standardised testing (ERB for younger children, ISEE or SSAT for older), an in-school visit, and a parent interview. Sibling and US Embassy preference exist but are not absolute. Apply 12 to 14 months in advance; ASL operates a rolling waitlist but it is not endless.
Tuition in 2026 to 2027 runs GBP 32,000 to GBP 41,000 per child by year group, with capital levy and ancillaries adding roughly 20 per cent. Total annual cost lands at GBP 45,000 to 55,000 per child. That is comparable to a top New York day school but the gap has narrowed; many New York independents have outrun ASL on price over the past five years. Model the comparison precisely in the fee calculator rather than relying on intuition.

The British school options
If the family expects to be in the UK long term, or if the child is academically strong and ambitious for UK universities, the British independent route is worth serious consideration. Several categories of school sit within this. The traditional London day schools (Westminster, St Paul's Boys, St Paul's Girls, City of London Boys, City of London Girls, Highgate, Latymer) deliver the strongest academic outcomes but operate ferociously competitive 11+ and 13+ entry assessments. American children switching mid-stream are at a structural disadvantage on the verbal reasoning and English papers without targeted tutoring.
The international British schools (ICS, Southbank, Halcyon) blend British curriculum with international cohorts and offer easier mid-stream entry. The smaller selective day schools (Channing, Mill Hill, Putney High, Francis Holland) sit slightly below the top tier on academic intensity but still deliver strong outcomes and are more receptive to transferring families. And the prep schools (for children below year 9) can be a useful staging ground if the family arrives with a year or two before the major senior school entrance points.
The single most important practical step for British school admission is the assessment preparation. The standard UK schools use the ISEB Common Pre-Test at year 6 and 7+, 8+ or 11+ school-specific papers thereafter. American children typically need three to six months of focused tutoring in English comprehension, verbal reasoning and the British mathematics syllabus before sitting these papers. Several London tutoring firms (Keystone, Bonas MacFarlane, KP Education) specialise in the transition; budget GBP 2,000 to GBP 5,000 for a tutored campaign across an academic year.
The IB schools
For families who want to keep university options genuinely open between the US and UK, an IB school is often the sensible middle path. London has a strong IB sector. Southbank International (three campuses) runs PYP through Diploma. Marymount London is the main Catholic IB option. ICS London offers a flexible IB programme. Halcyon London International School and ACS Cobham (just outside London) also deliver Diploma. King's College School in Wimbledon offers a strong IB Diploma alongside its A-Level cohort, and several traditional British schools (Sevenoaks, Tonbridge) run dual IB and A-Level sixth forms.
IB schools typically have more capacity than the top British day schools and more flexible entry windows. Admissions tend to involve school report review, a visit, an interview and an English assessment rather than a competitive examination. Fees in the IB sector run GBP 27,000 to GBP 35,000 per year for tuition, with the standard ancillaries bringing total annual cost to GBP 35,000 to GBP 45,000.
The 12 to 15 month timeline
The London school search should begin in late summer or early autumn of the year before the move. By September of the prior academic year, you should have a shortlist of three to five schools and be requesting application materials. Test registration deadlines for the strongest British schools fall in October and November. ASL applications close in late autumn for the following September. IB schools accept applications on a more rolling basis but the desirable September start fills by spring.
By January of the application year, applications are submitted and the child is in any required testing. By March, offers begin to arrive. By April, you have accepted an offer and paid the deposit. Between April and the August move, you handle the practical logistics: uniform, transport, medical records and visa where applicable. Read our mid-year relocation guide if your timeline is compressed.
Neighbourhoods to consider
School location drives housing location in London more than the reverse. ASL families typically live in St John's Wood, Maida Vale, Marylebone or Hampstead, all within easy commute of the school. Families at Westminster or City of London cluster in central London (Belgravia, Knightsbridge, Westminster itself). Families at St Paul's Boys, Latymer or Hammersmith schools sit west, in Chiswick, Barnes, Richmond and Hammersmith. Highgate and Channing families live in Highgate, Hampstead and Crouch End.
Catchment matters less than in New York's public school system because most relevant London schools are fee-paying and admit from anywhere. But commute time matters: London traffic is unkind to children, and a 25-minute walk to school is materially better than a 45-minute drive. Test the commute on a Tuesday morning during term time before you sign the housing lease.
Cost differences between the two cities
| Cost item | New York (USD) | London (GBP) |
|---|---|---|
| Top day school tuition | $60,000 to $68,000 | £28,000 to £35,000 |
| ASL or comparable | N/A | £32,000 to £41,000 |
| Standard British day school | N/A | £23,000 to £30,000 |
| Family home rent (4 bed) | $15,000 to $25,000 / mo | £7,000 to £15,000 / mo |
| Family healthcare | $25,000+ / year | £0 (NHS) to £8,000 (private top-up) |
The headline finding is that London is meaningfully cheaper than New York at most income levels, even before tax. The school fee differential alone runs USD 20,000 to USD 35,000 per child per year at the top tier, and the housing and healthcare differentials are larger. Run your own numbers in the cost calculator to see your situation. Most New York families find the move improves family discretionary income, which can offset the emotional cost of the relocation itself.
Common mistakes to avoid
Three mistakes are common enough to flag. The first is assuming American children will be tutored by the British school after admission to bring them up to syllabus. Few schools do this systematically; tutoring is the family's responsibility. Budget for it from the start.
The second is failing to register for testing dates in time. The competitive British schools all run their assessments in January or February, with registration closing in late autumn. Miss the registration window and your child is not in the assessment pool, regardless of how strong they are academically. Calendar this from September a full year before the move.
The third is moving in summer with no school place confirmed and trusting that "London will sort itself out." It will not. The capacity-constrained schools fill by Easter; the open-capacity schools have less control over the academic year start. A family arriving in August without a confirmed school place is usually looking at a holding placement at a mid-tier school and a transfer attempt later.

FAQ
Twelve to fifteen months before the move. London's top American, British and IB schools have waitlists running 12 to 18 months for popular year groups. Year 7 entry at the high-prestige British schools and year 9 entry at Westminster, St Paul's or City of London Boys are particularly competitive; assessment deadlines fall a full year before the September start.
It depends on the child's age and where the family expects to be at sixth form. Below age 11, the curriculum switch is usually painless. Between 11 and 14, the transition adds work but is manageable. Above 14, families generally stay within the American or IB pathway at ASL or one of the IB schools, because shifting to A-Level mid-stream is structurally difficult.
Tuition at ASL in 2026 to 2027 sits between GBP 32,000 and GBP 41,000 per child depending on year group. With capital levy, transport and the standard ancillaries, plan on GBP 45,000 to 55,000 all-in per child per year. ASL is comparable in pricing to top New York day schools but the full cost gap to Manhattan independents has narrowed over the past three years.
For some families, yes. Outstanding state primaries and grammar-school equivalents in outer London are genuinely excellent. The catch is admissions: state school places are catchment-based, and the strongest schools require a UK address before allocation. For families with flexible timing and willingness to live near a target state school, the cost saving is substantial.
