London has the deepest selective private and international school bench in the world but VAT on fees has lifted the all-in load by roughly 20 percent since January 2025. Sydney offers fewer pure international schools but a strong independent and IB sector with more space, more daylight and a fundamentally different family lifestyle. Both protect portable credentials to age 18.
Schools landscape side by side
London's international bench is led by ACS International Schools (Cobham, Hillingdon, Egham), the American School in London, the International School of London, ICS London, Southbank International and Halcyon London International. Add the wider British independent sector, including King's College School Wimbledon, Westminster, St Paul's, City of London, Dulwich and Eton (boarding). Selective British prep and senior schools assess from Year 3 onwards and increasingly run their own deferred entry pipelines. See our London city guide for the full school landscape.
Sydney's international families typically pick from a strong independent sector rather than a deep international-school bench: Sydney Grammar, Cranbrook, The King's School Parramatta, SCEGGS Darlinghurst, Ascham, Knox Grammar and Pymble Ladies' College sit at the top. Pure IB options include the International Grammar School in Ultimo and a handful of full IB continuum providers. Most of these schools follow the NSW HSC with IB Diploma as an option in senior years.

Fees and value for money
London international school senior fees in 2026 run GBP 28,000 to GBP 42,000, with the most selective British independents above GBP 35,000. VAT at 20 percent applies on most private school fees from January 2025, lifting the all-in load materially. Add GBP 2,000 to GBP 5,000 in registration, deposit and capital contributions in Year 1. The British VAT change hit family budgets harder than any other policy shift in the past decade.
Sydney private school fees for Year 11 and 12 land between AUD 30,000 and AUD 56,000 at the premium independents and IB schools. Building and capital levies add AUD 5,000 to AUD 15,000 per year on top of tuition. Schools apply a temporary-visa premium of 10 to 30 percent on top of domestic rates in many cases. The five year load typically lands AUD 30,000 to AUD 80,000 lighter than equivalent London independents post-VAT.
Curriculum availability
London is the natural home of the British curriculum from EYFS to A Level and runs the deepest IB Diploma bench in Europe. Sydney delivers the NSW HSC for the local independent sector and offers IB Diploma at a smaller but well-established set of schools. American AP pathways are scarce in Sydney compared to London. Either city protects portable credentials, but London is the safer choice for families likely to move back to the UK system.
Neighbourhoods families pick
London families cluster in Chelsea, Kensington, Notting Hill, Hampstead and Wimbledon for proximity to ACS, ASL and the top British preps. A four-bedroom flat in Chelsea or Kensington runs GBP 7,000 to GBP 15,000 per month; a townhouse in Wimbledon Village runs GBP 5,000 to GBP 10,000 with more garden and easier school logistics.
Sydney families pick the Eastern Suburbs (Bellevue Hill, Bondi, Vaucluse) for Cranbrook and SCEGGS access, the Lower North Shore (Mosman, Cremorne) for Shore and Wenona, and the Upper North Shore (Wahroonga, Pymble) for Pymble and Knox feeder routes. A four-bedroom house in Mosman runs AUD 3,500 to AUD 6,500 per week; equivalent property in Bellevue Hill runs AUD 5,000 to AUD 9,000.
Lifestyle and climate
London wins on global connectivity, cultural depth and the sheer breadth of weekend day trip options across Europe. Sydney wins on weather, beaches, sport, outdoor childhood and a far shorter commute for most family setups. The schoolyear runs January to December in Sydney rather than September to July, which matters if you are moving mid-year from a Northern Hemisphere school.
Verdict: who picks which city
Choose London if you want global connectivity, the deepest selective school bench and a clear path back to the UK system. Choose Sydney if you want outdoor childhood, a calmer family rhythm and lower five year school fee exposure post-VAT. Most families we work with run both cities through the cost calculator and the school finder quiz before committing.
Frequently asked questions
Is London or Sydney cheaper for international school families in 2026?
Sydney is meaningfully cheaper post-VAT. Comparable independent school fees run 15 to 30 percent lower in Sydney than in London once the UK's 20 percent VAT on private school fees is applied. Housing costs are broadly similar in prime suburbs.
Which city has better international schools?
London has the deepest selective bench in the world, especially for IB Diploma and British A Levels. Sydney's independent sector is strong but international schools per se are fewer. Choose by curriculum fit, not school count.
Is the family visa easier in London or Sydney?
Sydney is slightly slower but more predictable for skilled workers with employer sponsorship. The UK Skilled Worker route is fast but tightening yearly. Both readily admit spouse and children of the principal applicant.
Does VAT on UK private school fees apply to international families?
Yes. From January 2025, the UK applies 20 percent VAT on most private school fees regardless of family nationality. International schools that meet narrow exemption criteria may avoid VAT but most British independents pass it on in full.
Where do most international school families live in each city?
London families cluster in Chelsea, Kensington, Notting Hill, Hampstead and Wimbledon. Sydney families pick the Eastern Suburbs, Lower North Shore and Upper North Shore depending on the school they target.
