Entry Requirements for KCL Computer Science
A-Levels
The standard requirement is AAA, which must include grade A in Mathematics or Further Mathematics. If you're taking linear A-levels in England, you'll also need to pass the practical endorsement in all science subjects, with an exception for private candidates unable to take the practical component. KCL does not consider the EPQ at any point in the assessment process.
A contextual offer of AAA is available for eligible applicants, still requiring grade A in Mathematics or Further Mathematics. KCL's contextual admissions policy takes wider circumstances into account, similar to the additional criteria used for EMDP in Medicine, though the eligibility factors differ by programme. Check KCL's contextualised admissions page for the current criteria.
A-level General Studies, Critical Thinking, Thinking Skills, and Global Perspectives are not accepted as one of your three A-levels under either the standard or contextual offer.
International Baccalaureate
The standard requirement is 39 points overall, or an aggregate of 20 from three Higher Level subjects, including grade 6 in Higher Level Mathematics or Further Mathematics. The 39-point total includes TOK and EE. Students on the new IB Maths curriculum need either Analysis and Approaches or Applications and Interpretation at Higher Level to meet the subject requirement.
The contextual IB requirement is 36 points overall, or an aggregate of 18 from three Higher Levels, again including grade 6 in Higher Level Mathematics or Further Mathematics.
Access to Higher Education Diploma
The standard route requires a 60-credit Access to HE Diploma with 45 Level 3 credits overall, of which 42 must be at Distinction and 3 at Merit. The diploma must be in a relevant subject (Computing, Mathematics, Science, or similar) and include at least 15 Level 3 credits in Mathematics at Distinction.
The contextual route requires the same 60-credit, 45 Level 3 credit structure, but with 36 credits at Distinction and 9 at Merit instead.
Graduate Applicants
If you've completed or are completing a degree, KCL generally considers a UK Bachelor's degree with a 2:1 profile (or overseas equivalent) as meeting entry requirements, though applicants predicted or achieving a high 2:1 or First are viewed more competitively. Subject requirements still apply: if you didn't study Maths to the required level at A-level, KCL may instead look for significant Mathematics content within your degree, graded 2:1 or above on those modules.
Tuition Fees
International tuition for the Computer Science BSc is approximately £40,450 per year. Total estimated annual cost, including living expenses, books, and other costs, runs to roughly £61,000 per year for international students, though these figures should always be checked directly against KCL's current published fees before budgeting, as they change between admissions cycles.
UK home students pay the government-regulated tuition fee rate, currently £9,535 per year, the same across most KCL undergraduate programmes.
Course Structure and Accreditation
Computer Science at KCL is a three-year BSc taught within the Department of Informatics, part of the Faculty of Natural, Mathematical & Engineering Sciences. The course is professionally accredited by BCS, The Chartered Institute for IT, giving your qualification recognised standing within the UK tech industry.
Student life around the course includes a active culture of tech-focused societies: game development, women in computer science, robotics, and regular hackathons, careers panels, and talks. KCL's research strengths in the department span areas including AI, cybersecurity, and health technology applications.
Rankings and Graduate Outcomes
KCL ranks 6th in the UK for producing the most employable graduates, according to the Times Higher Education Graduate Employability Rankings 2025. KCL overall sits at 31st globally in the QS World University Rankings 2026, with strong subject-level reputation across STEM disciplines reinforced by its position in London's tech and finance job market, a genuine practical advantage for Computer Science students seeking internships and placements during their degree.
Computer Science, alongside Medicine, Law, Dentistry, and Business Management, is consistently named among KCL's most oversubscribed undergraduate programmes, meaning entry requirements and competition both run higher here than for many other courses at the university.
How to Apply
Applications go through UCAS using course code G400, institution code K60. The equal consideration deadline is 29 September 2026 for this course; applications after this date may still be considered if places remain, but without guaranteed consideration. As with most KCL undergraduate programmes (excluding research-focused and some specialist courses), an interview is not typically required for standard entry to Computer Science.
If you're applying after the equal consideration deadline or didn't receive an offer, see the King's College London Clearing 2026 guide for how the Clearing process works and what to do on results day.
Planning Your Move to London
Computer Science students at KCL are based primarily at the Strand Campus, in the Department of Informatics. If you're researching the course, attending an open day is a strong way to speak directly with current Informatics students about workload, the tech society scene, and what the Strand-based teaching actually involves. See the King's College London open days 2026 guide for confirmed dates.
Once you have an offer, accommodation near the Strand Campus becomes the next practical decision. For a full breakdown of costs and the best areas for Strand-based students specifically, see the complete guide to King's College London accommodation.

Final Verdict
KCL's Computer Science BSc combines a genuinely strong academic and accreditation profile with one of the best graduate employability records in the UK, set against a tough AAA entry bar that reflects just how oversubscribed the course is. If your Maths grade and overall profile are strong, it's a course worth building your application around specifically, rather than as a backup to another subject.
