IELTS vs Cambridge Exam in London: Which to Choose 2026

If you are studying English in London and need a certificate, choose IELTS for university applications, UK visas or work permits you may repeat every two years, and choose a Cambridge exam (B2 First, C1 Advanced or C2 Proficiency) for a permanent qualification that proves your level for life. Both exams are respected across the UK and worldwide, but they test English in different ways and cost different amounts. This guide from The London Community, the free platform helping international students find English schools, accommodation and events in London, UK, will help you pick the right one and find a good preparation course.

We speak to hundreds of students every month, and the same question keeps coming up in our community chat: should I take IELTS or a Cambridge exam? The honest answer is that it depends on your goal, your budget and how long you plan to stay in London. Let us walk you through it.

The short answer: which exam is right for you?

Pick IELTS Academic if you want to study at a UK university, apply for a Student route visa, or work as a nurse, doctor or teacher in the UK. Pick IELTS General Training if you are applying for a Skilled Worker visa or for immigration to Australia, Canada or New Zealand. IELTS scores are valid for two years, so you may need to sit it again later.

Pick a Cambridge English Qualification (B2 First, C1 Advanced or C2 Proficiency) if you want a certificate that never expires, if you enjoy studying towards a fixed level over 10 to 12 weeks, or if you want a qualification that looks strong on a CV in Europe. Cambridge exams are also accepted by most UK universities and by UK Visas and Immigration for many visa routes, which surprises many students.

If you are still unsure, you can try our AI school matcher and it will ask about your goal, your current level and your budget, then suggest schools in London that specialise in the right exam for you.

How the two exams compare at a glance

Below is a quick side by side so you can see the main differences. Prices are for tests taken in London in 2026 and are correct at the time of writing.

If you plan to stay in the UK for a long time and want proof of your English level for future job applications, a Cambridge certificate is a smart investment because you never need to retake it. If you are here for a specific short term goal like starting a Master's degree in September, IELTS is usually faster and simpler.

IELTS: what to expect on test day

IELTS has four parts: Listening (30 minutes), Reading (60 minutes), Writing (60 minutes) and Speaking (11 to 14 minutes). Listening, Reading and Writing are done in one sitting, usually in the morning. The Speaking test can be on the same day or up to seven days before or after your written papers.

In London, the biggest official IELTS centres are the British Council in Spring Gardens near Trafalgar Square (Charing Cross tube, Zone 1), IDP at Kings Cross and several test venues in Stratford and Barbican. Most students choose the computer delivered IELTS because results arrive within 3 to 5 days rather than waiting almost two weeks for the paper version.

The scoring uses bands from 0 to 9. Most UK universities ask for an overall band of 6.5 with no section below 6.0 for undergraduate courses, and 7.0 for postgraduate courses. For a Student route visa on a pre-sessional English course, you usually need at least IELTS 4.0 in each skill. Always check the exact requirement of your university or visa before you book.

Should you take IELTS on paper or computer?

The content is identical, but the computer version has an on screen timer, faster typing for the Writing paper, and much quicker results. Choose paper only if you find typing difficult or if you are used to writing essays by hand. Both versions cost the same and are accepted equally.

Cambridge exams: B2 First, C1 Advanced and C2 Proficiency

Cambridge English Qualifications are level based, which means you register for one specific CEFR level and either pass, fail or get a grade above or below. The most popular in London are B2 First (upper intermediate, sometimes still called FCE), C1 Advanced (advanced, sometimes called CAE) and C2 Proficiency (near native, sometimes called CPE).

Each Cambridge exam has four papers: Reading and Use of English, Writing, Listening and Speaking. The Speaking test is done in pairs, which many students find less stressful than the one to one IELTS interview. Cambridge is famous for its Use of English section, which tests grammar, vocabulary and word formation in ways that IELTS does not. If you enjoy learning grammar rules and word families, you will probably enjoy preparing for Cambridge.

Cambridge exams are held on fixed dates, usually two or three times a year for each level. This means most language schools in London build their courses around these dates, running 10 to 12 week programmes leading straight to the exam. If your school year is flexible, this fixed structure can be a big help because you always know what you are working towards.

Which Cambridge exam matches your level?

B2 First is aimed at learners who can hold a confident conversation, read a newspaper article and write a short essay. C1 Advanced is for learners who can follow a lecture, write a report and negotiate in English. C2 Proficiency is close to a well educated native speaker and is often used by future English teachers or translators. If you do not know your level, most schools in our directory offer a free placement test before you enrol.

Cost comparison: exam fees plus course fees

The exam fee is only part of the total cost. The real question is how much you will spend on preparation. Below is a typical London budget in 2026 for a 10 week preparation course of 20 lessons per week, plus the exam fee.

Schools in central London (Zone 1, near Oxford Circus, Holborn or Covent Garden) usually cost 20 to 30 percent more than schools in Zone 2 areas like Camden, Angel or Bethnal Green. The travel time is often only 10 to 15 minutes on the Tube, so budget conscious students can save hundreds of pounds by studying slightly further out. You can browse our school listings and filter by area, price and exam type.

Which exam do UK universities and employers prefer?

All Russell Group universities in London, including UCL, King's College London, Imperial College London, LSE and Queen Mary, accept both IELTS Academic and Cambridge C1 Advanced or C2 Proficiency. The key difference is that IELTS is more common for foundation and pre-sessional programmes, while Cambridge certificates are often preferred by students who finished secondary school abroad and want to prove their English level once and for all.

For UK employers, especially in customer facing roles or graduate schemes, a Cambridge certificate on a CV is often seen as more impressive because it shows years of structured study. IELTS is more common for regulated professions like healthcare, where the specific IELTS for UKVI or the Occupational English Test is a legal requirement.

If you are unsure what your target university or employer wants, look at their admissions page or job advert. Most list specific score requirements. You can also ask the community in our Q&A section, where students who applied to the same universities share their experiences.

The best English schools in London for exam preparation

You can prepare for either exam at almost any of the 55 accredited schools in our directory, but some schools specialise. Look for these signs when you compare options.

• Accreditation: The school should be British Council accredited and a member of English UK. This is required for visa students and a good sign for everyone else.
• Fixed exam dates: Cambridge preparation courses should end just before an official Cambridge test session (usually March, June, August and December).
• Small classes: Look for 12 to 15 students per class. Anything above 18 makes speaking practice much harder.
• Mock exams: A good preparation course includes at least two full mock tests with written feedback.
• Registered test centre: Some schools are approved IELTS or Cambridge test venues, meaning you can sit the exam in the same building where you studied.

Popular exam prep schools in London include those in Bloomsbury (near Russell Square tube), Covent Garden (Piccadilly line), Camden (Northern line, Zone 2) and Greenwich (DLR, Zone 2 or 3). Travelling by bus can also save money: routes 24, 29, 55 and 73 cover many of the main language school areas for £1.75 per journey with a contactless card.

Booking your exam in London

Book your IELTS through the British Council or IDP websites at least four weeks before your target date, as popular dates in June, July and September fill quickly. Book your Cambridge exam through your school if possible, or directly through an authorised centre like the Central School of English or International House London.

Bring your passport (or Biometric Residence Permit) on test day. Photocopies are not accepted. Arrive 30 minutes early because ID checks take time, and remember that you cannot bring your phone, watch or bag into the exam room. Most centres provide free lockers.

Preparation tips from students who passed

Set a realistic timeline. Most students move up half a band in IELTS (for example, from 5.5 to 6.0) with 8 to 10 weeks of focused study at 20 lessons a week. Going from B2 to C1 for Cambridge usually takes a full academic term of 12 weeks.

Practise every skill every week. It is tempting to focus only on your weakest area, but the exams reward balance. Read a British newspaper like The Guardian for 15 minutes daily, listen to BBC Radio 4 podcasts on your walk to school, and speak English with classmates at lunch instead of switching to your first language.

Join community events to practise in a natural setting. Free language exchanges at London bookshops, museum tours and student meetups all count as speaking practice. You can check upcoming community events on our platform, and many of them are free.

Which exam should you choose?

Choose IELTS if you have a specific university offer or visa deadline within the next year, if you want fast results, or if you are moving on to another country soon. Choose a Cambridge exam if you want a permanent certificate, if you enjoy structured grammar study, or if you plan to stay in the UK long term.

Whichever you pick, remember that your preparation matters more than the exam itself. A good teacher, small classes and regular practice will get you the score you need. To find the right school for your budget and level, use our matcher or read more articles in our blog for local advice.

Good luck, and welcome to London. You will do great.
