All UK universities will ask you for an English language test certificate as part of your application. The level that you need to achieve depends on the test you take and the course and university you are applying for.
All UK universities accept IELTS (International English Language Testing System) as proof of English ability. IELTS is the world’s most popular English language proficiency test for higher education and global migration, accepted by more than 10,000 organisations worldwide. IELTS is jointly owned by the British Council, IDP: IELTS Australia and Cambridge Assessment English.
