Sitting IGCSEs as a Private Candidate in the UK: Centres, Costs and Deadlines

By Brendaliz Chelangat, Head of Academics · November 2026 · 8 min read · First published

Every home-educated child in the UK who wants IGCSEs or A-Levels sits them as a private candidate: a student entered by an exam centre that is not their school. It works well, but it rewards planning, because centres fill up and deadlines arrive early. This guide covers how to find a centre, what it costs, when to enter, and the subject choices that make life easier.

Why IGCSE rather than GCSE

Many GCSEs include non-exam assessment, practical endorsements or spoken assessments that the entering centre must supervise, and few centres take that on for private candidates. Cambridge and Pearson Edexcel IGCSEs are assessed by written exam, with options designed for private candidates, so most home educators choose them. Sixth forms, colleges and universities accept IGCSEs alongside GCSEs.

Finding a centre

Cambridge and Pearson each publish lists of UK centres that accept private candidates; independent schools, further education colleges and specialist exam centres all appear on them. Contact two or three near you early in the year, ask which boards and subjects they take, their fees and deadlines, and how they handle access arrangements. Some centres also run the November series, useful for resits and for students ready early.

What it costs

Centres set their own fees, which usually combine the board's entry fee with the centre's own administration and invigilation charge, so the total per subject varies widely across the UK. Ask for the full price per subject in writing, including any late-entry fees, before you commit. Smartious tuition fees are separate: from USD 423 a month for Primary, varying by curriculum and level.

Deadlines

Exam boards set entry deadlines for each series, and centres set their own earlier ones so they can process entries in time. For the summer series, centres commonly ask for entries in the winter or early spring before; for the November series, by late summer. Late entries cost more or are refused, so treat the centre's date, not the board's, as your deadline.

Sciences and practicals

Science practicals are the part private candidates worry about most. Cambridge IGCSE sciences offer an Alternative to Practical paper, a written paper that tests practical skills without a laboratory session, which most private candidates take. Pearson Edexcel International GCSE sciences assess practical skills through the written papers. Check the current specification for each subject before you choose.

Access arrangements

Students with SEND or medical needs may be entitled to access arrangements such as extra time or a separate room. The centre applies for them and needs evidence, often an assessment by a specialist assessor, well before the exam. Raise it at your first conversation with the centre.
