Is there any English language test other than IELTS required?

No, IELTS is not the only English language test accepted.

UK universities also accept alternatives such as TOEFL iBT, PTE Academic, Cambridge English qualifications (C1 Advanced, C2 Proficiency), Duolingo English Test, and Oxford Test of English. Some universities may waive the English test if your previous education was in English and you provide a Medium of Instruction (MOI) certificate.

For the UK student visa, a UKVI-approved test (like IELTS for UKVI or PTE Academic UKVI) is usually required unless your university confirms your English proficiency through official admission documents.
