King’s InterHigh vs Sophia High School comes down to scale and price against class size: for 2026/27, King’s InterHigh charges £4,395–£10,990 a year on its annual contract (VAT included where applicable, the same price for every family), with timetabled 40-minute live lessons that are all recorded and an average of 20 students in its interactive Explore lessons; Sophia High School charges £9,600–£13,455 a year (plus VAT for UK residents only), with 100% live lessons, cameras on, in core classes of six to eight (official fees pages of both schools, checked 20 October 2026). Both are British online independent schools accredited by the Department for Education through the Online Education Accreditation Scheme (OEAS), and both lead to Pearson Edexcel or Cambridge international qualifications.
If you searched “King’s InterHigh vs Sophia High School”, “best online British school”, “Sophia High School fees” or “King’s InterHigh fees”, you have probably narrowed your list to these two and want a straight answer: which one fits your child, what each really costs by key stage, how the school day differs on screen, and whether one is “better”. This page compares them side by side using only the two schools’ own websites and the official Ofsted/DfE records, answers the questions parents most often ask, and then sets both beside Minerva Virtual Academy and NIJIN GLOBAL ACADEMY (NGA) — a different kind of online school for ages 6–18 that opens in September 2027 — for families who find that neither quite fits.
The short answer: which family fits King’s InterHigh, which fits Sophia High School
- King’s InterHigh fits families who want a large, established online school at a lower published fee — £7,250 a year for GCSE (Years 10–11) on the annual contract — with lesson recordings available 24/7, so a missed lesson can be watched later.
- King’s InterHigh fits students in the Middle East or Southeast Asia who want a British school on their own clock: at registration you choose a UK (GMT), Middle East (GMT+4) or Southeast Asia (GMT+7) timetable.
- King’s InterHigh fits sixth-formers who want the IB Diploma as well as A Levels, families who need to start any time of year (enrolment takes from 48 hours to two weeks), and families who want a rolling contract they can cancel at the end of any half term.
- Sophia High School fits children who do best when the teacher can see every face: core classes of six to eight, cameras on, 25+ hours of live teaching a week, plus weekly parent consultations and one-to-one mentoring listed in the fee.
- Sophia High School fits families with younger children from Reception (age 4), athletes who want a custom timetable built around training or travel, and students who want to sit Pearson Edexcel exams from home under remote invigilation.
- Neither may fit families in the Americas who need live lessons in their own daytime (neither school publishes an Americas timetable), families who want tutor-supported homeschooling rather than a daily timetable (Wolsey Hall Oxford is closer), or children still learning English who would benefit from a bilingual mentor — the gap NIJIN GLOBAL ACADEMY is designed for, though it does not open until September 2027.
King’s InterHigh and Sophia High School at a glance (official data)
King’s InterHigh is part of Inspired Education Group and describes itself as trusted by 6,000 families across more than 120 countries. It teaches the British curriculum from Year 3 to Year 13 (ages 7–19), including IGCSEs, A Levels and what it calls the first fully online IB Diploma. Sophia High School was founded in 2020 by a leadership team of former headteachers and senior leaders; it teaches the National Curriculum for England from Reception to Year 13 (ages 4–18) and positions itself as a premium British online independent school with “market-leading small class sizes”.

King’s InterHigh fees vs Sophia High School fees (2026/27, official)
All figures below come from the King’s InterHigh fees page and the Sophia High School fees page, checked on 20 October 2026. Both quote fees in pounds sterling, per year, for the 2026/27 academic year. King’s InterHigh also shows a rolling (per half term) price; Sophia lets families pay annually or termly but does not publish the termly amount.
| Stage | King’s InterHigh — annual contract (per year) | King’s InterHigh — rolling contract (per half term) | Sophia High School (per year) |
|---|---|---|---|
| Primary | £4,395 (Years 3–6, ages 7–11) | £955 | £9,600 (Reception–Year 6, ages 4–11) |
| Key Stage 3 | £5,995 (Middle School, Years 7–9) | £1,360 | £10,815 (Lower Secondary, Years 7–9) |
| GCSE / IGCSE | £7,250 (Years 10–11) | £1,590 | £13,455 (Years 10–11) |
| A Levels | £7,585 (based on 3 subjects; 1–5 possible) | £1,780 | £13,455 (three International A Levels) |
| IB Diploma | £10,990 (annual contract only) | Not offered on rolling | Not offered |
| Extra subjects | Primary £405; Middle £435; GCSE £835 (or £545 “assured”) per subject per year | £83.50 / £89 / £168 (or £127 assured) | £4,250 per additional IGCSE or A Level subject per year |
| Registration | £100 one-off | £100 one-off, non-refundable (covers the live assessment lesson) | |
| Deposit | Annual contract: £500 for UK students, £1,000 outside the UK | £1,000 admissions deposit on acceptance, offset against your first invoice | |
| VAT | Same price for all students; “VAT included where applicable” | “All fees +VAT for UK residents only” | |
| Exam fees | Not included; paid to the exam centre, typically £150–200 per qualification | Not included; remote invigilation from £150 per paper plus the standard entry fee | |
| Sibling discount | Annual contract only; amount depends on when the sibling joins (not published as a figure) | Available; amount not published on the official site | |
The VAT difference matters for UK families
The two schools treat VAT in opposite ways, and it changes the comparison. King’s InterHigh says it charges “the same fees to all students, regardless of the local VAT implications”, so £7,250 is the GCSE price whether you live in Manchester or Dubai. Sophia’s prices are “+VAT for UK residents only”: families outside the UK pay the listed figure, while UK residents add VAT. At the standard UK rate of 20%, Sophia’s £13,455 IGCSE or A Level fee would become £16,146 a year for a UK family (our arithmetic; Sophia does not publish VAT-inclusive figures).
Two years of GCSE/IGCSE at today’s prices
Using only the official 2026/27 numbers and assuming no fee rises, no sibling discount and the standard subject load:
- King’s InterHigh (annual contract): 2 × £7,250 + £100 registration = £14,600, plus exam-centre fees (typically £150–200 per qualification). The £500/£1,000 deposit is held and refunded on leaving, minus anything owed. On the rolling contract, a year is six half terms: 6 × £1,590 = £9,540 a year.
- Sophia High School, family outside the UK: 2 × £13,455 + £100 = £27,010, plus exam fees (remote invigilation from £150 per paper plus entry fees). The £1,000 deposit is offset against the first invoice, so it is not an extra cost.
- Sophia High School, UK-resident family: 2 × £16,146 + £100 = £32,392 at a 20% VAT rate (our arithmetic), plus exam fees.
Put simply, Sophia costs roughly twice as much per year at secondary level. What the extra buys, on Sophia’s own description, is much smaller classes (six to eight rather than an average of 20 in Explore lessons), cameras-on teaching, weekly parent consultations, small-group clinics and one-to-one mentoring. Whether that is worth it depends on your child. King’s InterHigh also lists a Technology Integration Fee whose amount is not published on the 2026/27 fees page, so ask for it when you request a quote. For a wider view of what online schooling costs compared with a physical international school, see our guide to online vs in-person international school costs and our overview of online British curriculum school fees.
Contracts and leaving
King’s InterHigh’s annual contract “saves” 30–41% against the rolling price (the fees page shows 30% for Primary up to 41% for A Levels) and can be paid upfront or monthly over ten months, September to June. Its enrolment FAQ asks for one full term’s notice to withdraw before the end of the year, or half a term’s notice to leave at the end of the summer term; the rolling contract can be cancelled at the end of any half term. Sophia publishes its £100 registration fee and £1,000 deposit but not its termly instalment amounts or a withdrawal-notice period on the pages we checked, so ask Admissions for the terms and conditions before you sign.
Live vs recorded lessons, class sizes, timetable and time zones
This is where the two schools are most different, and it matters more than the fee for many children.
King’s InterHigh runs a full timetable: “Each school day, your child will join timetabled, 40-minute lessons led by experienced teachers”, and “Every class is recorded and made available to access 24/7.” The secondary page gives an average of 20 students per class in its interactive Explore sessions. The recordings are a real strength for students who travel, train, have medical appointments or simply need to rewatch a difficult topic. When you register you choose one of three timetables — British time (GMT), Middle Eastern time (GMT+4) or Southeast Asia time (GMT+7) — so a family in Singapore or Dubai can have live lessons in their own daytime. The exact hours of each timetable are not published on the official site, and no Americas timetable is listed.
Sophia High School describes itself as “100% live lessons — never passive content”. Core classes have six to eight students, cameras are on, and students get 25+ hours of live teaching a week; A Level students have about five hours per subject per week. Lessons are recorded to each student’s Digital Notebook for review or catch-up after an approved absence — the recordings support live attendance rather than replace it. School hours are 8am to 4pm UK time (the site footer says 8am–4.30pm), with core lessons Monday to Thursday and Fridays for enrichment and Houses. Its “day in the life” shows form time with the same tutor each morning, a live core lesson at 09:30 and a one-to-one mentor check-in at 11:00. Sophia also mentions a custom timetable built around a child’s time zone, training or travel; separate regional timetables are not published on the official site.
In practice: a child in East Asia would find King’s InterHigh’s Southeast Asia timetable easier to follow live, while Sophia’s UK-hours core day would fall in the afternoon and evening there. A child in the UK or Europe can follow either. A child in North or South America would be studying UK hours (early morning or overnight) with either school, or relying on recordings. For a general picture of what a day looks like at any online school, read how an online international school works.
Terms are almost identical. Both start the 2026/27 year on 7 September 2026 (Sophia’s new students begin on 4 September). King’s InterHigh runs a 35-week year in three terms, with the Spring term starting in the week of 4 January 2027 and the Summer term in the week of 12 April 2027. Sophia’s autumn half term is 23–30 October 2026, and its last day of lessons in the summer is 9 July 2027.
Accreditation, inspection and qualifications
UK online schools are not “accredited” in the American sense. The relevant mark is the Department for Education’s Online Education Accreditation Scheme (OEAS), under which Ofsted assesses an online school against standards for safeguarding, teaching, curriculum and leadership. Both schools hold it.
- King’s InterHigh says on its accreditations page that it “is accredited by the UK government’s Department for Education (DfE) through the Online Education Accreditation Scheme (OEAS)”, after “a thorough assessment by Ofsted”, and links the report. It is also an accredited Cambridge International School approved by Cambridge International Education, a Pearson Edexcel Approved Online Centre, and offers the IB Diploma Programme online. Students take Cambridge IGCSEs and International AS/A Levels, Pearson Edexcel qualifications, or the IB Diploma.
- Sophia High School says on its accreditation page that it is accredited by the DfE through the Ofsted-delivered OEAS, is registered under URN 149905, and is an accredited member of the Independent Schools Association (ISA) and the Council of British International Schools (COBIS). It publishes its inspection report and says its next accreditation inspection is scheduled for autumn 2026, three years after its initial accreditation. It is a Pearson Edexcel Virtual Centre, one of a small number approved to run International GCSE and International A Level exams under remote invigilation from home.
Because both schools lead to recognised public exams (Cambridge or Pearson Edexcel international qualifications, and at King’s InterHigh the IB), the certificates students earn are the same certificates a pupil at a physical British school would receive. The practical difference is where exams are sat: Sophia offers remote invigilation for its Pearson exams; King’s InterHigh says exam fees are paid directly to the exam centre.
People also ask: honest answers
Which is the best online British school?
There is no single “best”: both King’s InterHigh and Sophia High School are DfE-accredited and teach towards recognised British qualifications. The better question is which model fits your child. If your child is self-motivated, benefits from rewatching lessons, or lives in the Middle East or Southeast Asia, King’s InterHigh’s scale, recordings and regional timetables are strong. If your child needs to be seen and heard in every lesson, Sophia’s classes of six to eight and cameras-on teaching are the point of difference. Our online international schools compared guide covers a wider field.
Why are Sophia High School fees higher than King’s InterHigh fees?
Sophia’s fees page lists what tuition includes: 25+ hours of live lessons weekly, classes of six to eight, UK-qualified specialist teachers, weekly parent consultations and a Parent Learning Portal, GL and CAT4 benchmarking, small-group clinics and one-to-one mentoring. Smaller classes need more teachers per student. King’s InterHigh operates at a much larger scale with average Explore classes of 20 and recorded lessons, which allows a lower fee. Neither approach is “right”; they are different products at different prices.
Are King’s InterHigh lessons live or recorded?
Both. Lessons are live and timetabled, taught by teachers in real time, and every lesson is also recorded and available 24/7. Students are expected to follow their timetable; the recordings help with catch-up and revision.
Do UK families pay VAT on online school fees?
At King’s InterHigh the listed price is the total for everyone, with VAT included where applicable. At Sophia, UK residents pay VAT on top of the listed fee; families living outside the UK do not. Check where you will be resident when you enrol, because that decides which figure applies.
Can my child join mid-year?
Yes, at both. King’s InterHigh accepts enrolments throughout the year, with no waiting list, and says enrolment takes at least 48 hours and up to two weeks. Sophia lets students enrol at the start of any half term, subject to places in the cohort, and says most families complete its four steps in two to three weeks.
Is there an entrance test?
King’s InterHigh is non-selective and requires no entry tests, though students must be fluent in English (its guide suggests around CEFR A2 for Primary and B1 for Secondary); the IB Diploma needs at least seven (I)GCSEs at grade 6 or above including English and Maths. Sophia’s process includes a live one-to-one assessment lesson with a teacher after the £100 registration; it offers EAL support but does not publish a formal English level.
King’s InterHigh vs Sophia High School vs NIJIN GLOBAL ACADEMY vs Minerva Virtual Academy (official data)
For families still deciding, here are both schools beside two other options. Minerva Virtual Academy is a smaller British online school with weekly one-to-one mentoring. NIJIN GLOBAL ACADEMY (NGA) is a different kind of school: an online international school for ages 6–18 focused on Asia and Oceania, not yet open.

Reviews and common concerns, answered honestly
Parents comparing these two schools raise similar questions. Here is what each school says officially, so you can weigh it yourself.
“Will my child get enough attention in a bigger online class?”
King’s InterHigh gives an average of 20 students in its Explore lessons and pairs live teaching with 24/7 recordings and a dedicated pastoral team. Sophia’s model is built around six to eight per class, cameras on and one-to-one mentoring. If your child tends to switch off unless called on, the smaller class may be worth the higher fee; if your child is independent and likes to rewatch lessons, the larger school may work well.
“Will my child be lonely?”
Both schools address this. King’s InterHigh lists co-curricular clubs and activities and a community across more than 120 countries. Sophia lists daily form time, four Houses, Friday enrichment and clubs, esports leagues and monitored socialisation classrooms. Many families also add local activities and sport.
“What about exams — where will my child sit them?”
Exam fees are extra at both schools. Sophia students can sit Pearson Edexcel exams from home under remote invigilation (from £150 per paper plus the entry fee) or at a physical centre. King’s InterHigh says exam fees are paid directly to the exam centre, typically £150–200 per qualification. Plan the exam centre early if you live outside a major city.
“Is the fee going to rise?”
Fees are set each year. King’s InterHigh’s fees page already shows a 2027/28 toggle alongside 2026/27, and Sophia publishes 2026–27 figures. Use each school’s calculator or ask Admissions for a written quote for your child’s start date.
“Can my child study from the United States or Canada?”
Both schools accept students worldwide, but neither publishes an Americas timetable. King’s InterHigh’s three timetables are UK, Middle East and Southeast Asia; Sophia’s core day runs on UK hours, with a custom-timetable option. Check the live-lesson times against your local clock before enrolling.
Alternatives if neither King’s InterHigh nor Sophia fits
Minerva Virtual Academy suits secondary students aged 11–18 who want live lessons with a weekly one-to-one mentor in a smaller community, at £9,365 for the 2026/27 annual fee (including a £500 deposit and £95 subscription), with a GST time-zone option. Read our Minerva Virtual Academy fees guide. Wolsey Hall Oxford suits families who want structured homeschooling rather than a daily live timetable: students work through mostly Cambridge courses with tutor-marked assignments and a Student Progress Manager, and pay per course or bundle plus a £95 registration fee — see our Wolsey Hall Oxford fees guide. Families aiming at selective universities who want an accelerated online school can also compare our Crimson Global Academy fees and review. For the full picture of each school in this comparison, see our separate King’s InterHigh fees and review and Sophia High School fees and review. If you are also weighing American-style options, our reviews of Laurel Springs School tuition and Stanford Online High School tuition cover two well-known US online schools.
NIJIN GLOBAL ACADEMY (NGA) is a different kind of option. It is an online international school for ages 6–18 focused on Asia and Oceania, opening in September 2027 (planned), with free trial classes monthly from September 2026 and pre-opening trial classes in April–May 2027. Its first cohort is 100 students, and it is operated by NIJIN Inc. in Japan, whose sister alternative school NIJIN Academy has more than 1,000 students. NGA does not rank children by test scores: lessons are small-group live dialogue (classes of about 8), subjects are learned in English with a bilingual English–Japanese mentor, English levels follow the CEFR, and students take part in social co-creation projects with companies and governments plus international exchange. An optional Cambridge IGCSE / A-Level pathway is listed on the curriculum and timetable page. There is no academic entrance exam and no English requirement; NGA can run alongside a local school or as the main school, and it travels with the family if they relocate. Tuition is not yet published; NGA says it will be far more affordable than a typical international school, with no enrolment, facility or uniform fees, materials included and sibling discounts.
Be clear about the trade-offs: unlike King’s InterHigh and Sophia, NGA is not yet open, not yet accredited, and has no graduates or track record. Its timetable is built for Asia–Oceania daytime, so for families in the UK, Europe or the Americas live classes may fall outside their day — check the timetable against your local time. If you want a DfE-accredited British school with published fees and exam results today, King’s InterHigh and Sophia High School are the schools to compare.

Choosing calmly
King’s InterHigh and Sophia High School are both serious, accredited British online schools; they simply make different promises. One offers scale, flexibility, recordings and regional timetables at a lower fee; the other offers small, cameras-on classes and close mentoring at a higher one. The most useful next step is to sit in on what each offers — an induction, a taster or an assessment lesson — with your child beside you, and notice where they lean in. Whichever you choose, the right school is the one where your child is known and keeps wanting to learn.
