Relocating to the UK with school-age children means one decision rises above all others: which school will keep your kids on track academically, socially, and for US college applications? The good news is that the UK has a stronger cluster of American and internationally accredited schools than almost anywhere else in the world. The challenge is knowing which one fits your family’s timeline, budget, and long-term plans.
This guide covers the flagship American school in London, the broader field of international options across the UK, and the practical details — curricula, fees, waitlists, and how to choose — that parents actually need when they’re mid-decision.
Key Takeaways

1. The American School in London: the flagship option
The American School in London (ASL) is the reference point for American families relocating to the UK. Founded in 1951, it sits in St John’s Wood, North London, and serves students from Pre-K through Grade 12 on a fully American curriculum. It is accredited by the Middle States Association of Colleges and Schools, the same body that accredits schools across the northeastern United States.
Curriculum: ASL follows a US-style program throughout, culminating in the American High School Diploma. Advanced Placement (AP) courses are offered across a wide range of subjects, and the school’s college counseling program is specifically geared toward US university admissions. Students applying to American colleges leave with transcripts, GPA calculations, and recommendation letters that US admissions offices recognize immediately.
Enrollment and size: ASL enrolls approximately 1,350 students across all grades, drawn from over 50 nationalities, though American families make up the largest single group.
Tuition (2025–2026): Fees range from roughly £30,000 per year at the lower school level to approximately £38,000 per year at the high school level. These figures are published on the ASL website and should be confirmed directly, as they are updated annually.
Admissions and waitlists: ASL is consistently oversubscribed, particularly at the middle and high school levels. The school recommends applying as early as possible, and families relocating for corporate assignments are advised to begin the process the moment a move becomes likely — not once it is confirmed. Rolling admissions are offered when places are available, but popular grade levels can carry waitlists of a year or more. ASL gives priority to siblings of current students and to families with confirmed London postings.
Who it suits best: Families on assignments of two years or more who want a seamless US academic experience and a clear path to American colleges. The school’s alumni network and college placement record are strong, and the community tends to be well-connected among the American expat population in London.
💡 Tip: Register your interest with ASL before your move is finalized. The admissions team can advise on likely availability for your child’s grade level and help you plan around the UK academic year, which runs September to July.
2. ACS International Schools: four campuses across the UK
ACS International Schools operates four campuses in the UK: Cobham (Surrey), Egham (Surrey), Hillingdon (West London), and Doha (outside the UK). The three UK campuses collectively serve students from Pre-K through Grade 12 and offer a choice of curricula that makes ACS particularly flexible for families uncertain about their length of stay.
Curriculum options: ACS offers the International Baccalaureate (IB) Primary Years Programme, Middle Years Programme, and Diploma Programme, alongside the American High School Diploma at the high school level. This dual-track approach means students can move between an IB pathway and a US diploma pathway depending on where the family ends up next.
Tuition: Fees vary by campus and grade level, generally ranging from approximately £20,000 to £35,000 per year. Cobham and Egham tend to sit at the higher end; Hillingdon is somewhat more accessible. Confirm current fees directly with each campus, as they are updated each academic year.
Admissions: ACS uses rolling admissions and tends to have more availability than ASL, though popular grade levels at Cobham can fill quickly. The schools have experience working with corporate relocation timelines and can often accommodate families with shorter lead times.
Who it suits: Families who want curriculum flexibility, particularly those who may move on to a third country where IB recognition is stronger than the US diploma, or those whose children may eventually enter the British university system.
3. TASIS The American School in England
TASIS England, located in Thorpe, Surrey, offers a Pre-K through Grade 12 American curriculum with a strong boarding option at the high school level. Founded in 1976, it is accredited by the New England Association of Schools and Colleges (NEASC) and the Council of International Schools (CIS).
Curriculum: The school follows a US-style program with AP courses at the high school level and a strong emphasis on college preparation for American universities. A small IB Diploma option is also available for students who prefer that pathway.
Tuition: Day fees for the 2025–2026 year run from approximately £22,000 at the lower school level to around £34,000 at the high school level. Boarding fees are higher. Verify current figures on the TASIS England website.
Admissions: TASIS tends to have more availability than ASL and processes applications on a rolling basis. The boarding program draws students from across Europe and beyond, which gives the high school a particularly international character.
Who it suits: Families based in Surrey or southwest London, and those considering a boarding option for high school students. The campus environment is notably different from a city school — green, residential, and structured.
4. The British School of Washington model, reversed: British curriculum schools for American families
Some American families in the UK choose a British independent school rather than an American or international one, particularly when the assignment is short or when children are young enough that curriculum continuity is less critical.
British independent schools — including well-known names such as Dulwich College, Alleyn’s School, and St Paul’s Girls’ School in London, or Eton and Harrow for boarding — follow the British curriculum leading to GCSEs and A-Levels. These qualifications are recognized by US universities, and many American students have successfully used A-Level results for US college applications.
Key consideration: A-Levels are subject-specific and narrower than the US diploma or IB, which can limit the breadth of a college application. Families planning a US college path should discuss this with a college counselor before committing to a British curriculum school for the high school years.
Tuition: British independent school fees vary widely, from roughly £15,000 to over £45,000 per year for day students, with boarding fees considerably higher at elite schools.
Who it suits: Families on shorter assignments (one to two years) with younger children, or those who want their children to integrate fully into British school life and are less concerned about maintaining a US academic track.
5. International schools in London beyond the American track
London hosts a wide range of international schools beyond the American-curriculum options, several of which are popular with American families who want strong academics without the specifically US-focused environment.
The International School of London (ISL) in Chiswick offers the full IB continuum from Primary Years through Diploma and is well-regarded for its multilingual program. Fees run from approximately £22,000 to £32,000 per year.
Nord Anglia Education operates multiple schools in and around London, including the British International School and the Nord Anglia International School, both offering IB programs. Nord Anglia’s global network is a practical advantage for families who move frequently.
Southbank International School has three London campuses (Hampstead, Kensington, and Westminster) and offers the IB from Pre-K through Grade 12. It is a popular choice for families in central and west London.
For American families, the IB Diploma is a strong US college application credential. Most selective US universities are familiar with IB grading and give it equal weight to AP-based transcripts.
6. American and international schools outside London
American families relocating to cities outside London have fewer dedicated American-curriculum options, but several strong international schools serve the major expat hubs.
Edinburgh: The American School of Edinburgh (Lomond School’s international program) and George Watson’s College both serve international families, though neither follows a purely American curriculum. The IB is available at several Edinburgh schools.
Manchester and the North: The Manchester Grammar School and Withington Girls’ School are highly regarded British independents. For a more international track, Cheadle Hulme School and Stockport Grammar School serve families in the Greater Manchester area.
Bristol and the Southwest: Clifton College offers both A-Levels and the IB Diploma and has experience with international families.
Cambridge and the East: The Perse School in Cambridge is a strong academic independent with IB options and a track record of US college placements.
For families outside London, the practical reality is that a British independent school with IB availability is often the strongest option. The key is to confirm whether the school has experience supporting students applying to US universities, as not all British schools are equally familiar with the Common App or SAT/ACT requirements.
7. How to choose the right school for your family
The right school depends on three factors more than any other: how long you expect to stay, where your children are in their schooling, and where they are likely to apply to university.
Length of stay matters most at the high school level. A child in elementary school can transition between curricula with relatively little disruption. A student entering Grade 10 or 11 mid-diploma is in a different position entirely. Switching from a US diploma track to A-Levels at that stage is difficult, and switching back is harder still. If your assignment is two years or fewer and your child is in high school, staying on a US or IB track is almost always the right call.
US college plans favor the American diploma or IB. Both are well understood by US admissions offices. A-Levels are accepted but require more explanation, and some students find the narrower subject focus works against them in holistic admissions processes that reward breadth.
Waitlists are real and move slowly. ASL and ACS Cobham in particular can have significant waitlists at popular grade levels. Apply early, apply to more than one school, and have a backup plan. British independent schools often have more availability and can serve as a strong interim option while you wait for a place at your preferred international school.
Admissions timing: Most UK schools, including international ones, operate on a September start. Applications for September entry are typically strongest in the January to March window of the same year, though rolling admissions mean later applications are considered when places exist. For ASL specifically, the school advises families to begin the inquiry process as soon as a London move is on the horizon.
💡 Tip: Ask each school directly whether they have experience supporting students applying to US universities. A school that regularly sends students to American colleges will have counselors who know the Common App, understand how to present British or IB credentials, and can write recommendation letters in the format US admissions offices expect.
