Imperial College London is one of the most selective universities in the world, and — alongside Oxford and Cambridge — one of the hardest to get into in the UK. It is a founding member of the Russell Group and a pure science, engineering, medicine, and business institution: there are no humanities or arts degrees here. That focus, combined with a place in the global top ten, makes Imperial extraordinarily competitive. Getting in means understanding what the headline numbers actually mean.
The real acceptance rate at Imperial
As with every elite university, two very different figures get quoted for Imperial, and the gap matters.
Applications received: very high across a relatively small number of STEM and medicine courses, so applications-per-place ratios are among the steepest in the country.

Review my statement → From £7.49 · Results in under 10 minOffers made: broadly in the 35–45% range across the institution — significantly lower than most Russell Group universities, and lower still on the flagship courses.
Enrolled students: the enrolment rate is in the low teens, but at Imperial the offer rate itself is the binding constraint: unlike a large civic university, Imperial does not hand out offers to most qualified applicants.
The key difference from most universities on this list: at Imperial, clearing the academic bar does not guarantee an offer. Because almost every applicant is predicted top grades, the college is choosing between candidates who all look excellent on paper. That makes everything beyond grades — admissions tests, the personal statement, and (for some courses) interviews — genuinely decisive.

Entry requirements by course
Imperial's offers are among the highest in the UK, typically ranging from A*AA to A*A*A, with mandatory admissions tests for several subjects.
| Course | Typical A-level Offer | Notes |
|---|---|---|
| Medicine (A100) | A*AA | Chemistry + Biology; UCAT required; interview (MMI) |
| Computing | A*A*A | Maths required; among the most competitive CS courses in the UK |
| Mathematics | A*A*A | STEP or MAT required; Further Maths expected |
| Aeronautical Engineering | A*A*A | Maths + Physics required |
| Mechanical Engineering | A*AA | Maths + Physics required |
| Electrical & Electronic Engineering | A*AA | Maths + Physics required |
| Chemical Engineering | A*AA | Maths + Chemistry required |
| Physics | A*A*A | Maths + Physics required |
| Chemistry | A*AA | Maths or another science |
| Biomedical Sciences / Biochemistry | AAA | Chemistry + Biology |
| Business (Management/Analytics) | A*AA | Maths required for analytics routes |
IB requirements: Imperial's standard IB offer sits between 38 and 42 points — among the highest in the UK — with 6s and 7s at Higher Level in the relevant subjects. Mathematics and the most competitive engineering courses sit at the top of that range.
Medicine at Imperial: the hardest door to open
Imperial's School of Medicine is one of the most competitive in the country, integrated with one of the largest NHS trusts in Europe.
Acceptance rate: a small single-digit percentage of applicants secure a place, with thousands of applications for a few hundred seats.
UCAT requirement: Imperial uses the UCAT to shortlist for interview (following the retirement of the BMAT). There is no fixed published cut-off; Imperial ranks applicants by score each cycle, so the effective threshold moves year to year. A score well above the annual average is effectively necessary to reach interview.
Interview format: Multiple Mini Interview (MMI), assessing communication, ethical reasoning, and motivation. With so many top-grade, high-UCAT applicants, the MMI is where places are won and lost.
Subject requirements: Chemistry and Biology at A-level — the standard demanding science combination, with an A* expected.
Engineering, Computing and Maths: the STEP/MAT factor
Outside Medicine, Imperial's flagship courses are its engineering and computing programmes, which carry A*A*A requirements and treat the personal statement as a serious differentiator.
For Mathematics, Imperial requires the STEP or MAT admissions test — a deep problem-solving paper that goes well beyond A-level Maths. Strong A-level grades are assumed; the test is what separates offers from rejections. For Computing, the bar is A*A*A including Maths, with applications-per-place ratios among the highest in the country. Across all of these, demonstrating genuine engagement with the subject — projects, reading, real problem-solving — matters because almost every applicant has the grades.
Rankings: what Imperial's position means
Imperial is one of a tiny handful of UK universities ranked in the global elite:
- QS World University Rankings 2026: consistently in the global top 10, and among the top few in the UK alongside Oxford and Cambridge
- Times Higher Education 2026: comfortably within the global top 20
- Complete University Guide 2026: top 5 in the UK, frequently top 3
- Research strength: world-leading across engineering, the physical sciences, and medicine
Imperial's standing in STEM is genuinely Oxbridge-level. For engineering, computing, and the physical sciences, it is one of the strongest universities in the world.
Imperial's history and Russell Group standing
Imperial received its royal charter in 1907, formed from a merger of earlier science and engineering colleges in South Kensington. It was a founding member of the Russell Group in 1994 and became fully independent from the University of London in 2007, marking its centenary.
In selectivity, Imperial sits in the very top tier of UK universities — with Oxford and Cambridge — and well above the rest of the Russell Group for the subjects it teaches.
Contextual offers at Imperial
Imperial operates contextual admissions. Eligible students — from under-represented backgrounds, low-participation areas, or with circumstances that have affected their education — may receive offers one to two grades below the standard requirement, and are considered with additional context. Some courses also run dedicated widening-participation and foundation routes (including for Medicine).
Eligibility is assessed from UCAS and contextual data; check Imperial's published criteria directly, as the specifics vary by department.
Who gets into Imperial?
For most Imperial courses, offers go to applicants who:
- Are predicted A*AA to A*A*A at A-level, with the relevant subject combinations (Maths and Further Maths for the quantitative courses)
- Sit and perform well on any required admissions test (UCAT for Medicine; STEP/MAT for Maths)
- Have a personal statement showing genuine, specific engagement with the subject — not just aptitude
Because the grade bar is so high and so many applicants clear it, Imperial is one of the universities where the personal statement and tests genuinely decide outcomes. Meeting the grades is the entry ticket, not the deciding factor.
Imperial vs. comparable universities
Imperial's only true peers in the UK are Oxford and Cambridge, and for many STEM subjects it competes with them directly for the strongest applicants. Students applying to Imperial typically also apply to Cambridge or Oxford, UCL, and one or two strong Russell Group sciences departments (Manchester, Bristol, Warwick) as more achievable choices.
Imperial's distinguishing feature is its single-minded focus: a global-elite institution that does only science, engineering, medicine, and business, in the heart of London. For those fields, it is as good as anywhere in the world.
The personal statement: what Imperial is looking for
At Imperial, admissions teams are choosing between candidates who almost all have top predicted grades. The personal statement is one of the few places where an applicant can stand out — and on courses without interviews, it carries real weight.
What they look for is evidence of genuine scientific or mathematical thinking: not a list of achievements, but engagement with the subject beyond the syllabus — problems you have worked on, ideas you have read about, projects you have built. A statement that shows you think like a scientist or engineer, rather than just that you are good at exams, is a meaningful advantage in a field of near-identical top applicants.
