With the spread of computing procedures and mathematical ideas into many areas, there is high demand for professionals who are expert in both.

Our Mathematics and Computer Science degrees are mathematical courses orientated towards computing science.

Taught jointly by the Departments of Computing and Mathematics, they provide a firm foundation in mathematics, particularly in pure mathematics, numerical analysis and statistics. They also cover all the essentials of computer science, with an emphasis on developing software, as well as more theoretical topics.

This makes the courses particularly suited to mathematically-able students with interests in both subjects.

Study programme

During the first two years you take core modules from both departments and complete project work, with the chance to choose some optional modules in the second year.

In the third year you can choose from a wide variety of optional modules offered by the departments to suit your interests, and will also complete a substantial individual project.

Transfer between courses

The high level of shared content means transfer between any of our Mathematics and Computer Science courses is usually possible at any time during the first year.

If you are an international student, transferring to a different course could have an impact on your Tier 4 visa. Please visit our International Student Support webpage for further information.


Please note that the curriculum of this course is currently being reviewed as part of a College-wide process to introduce a standardised modular structure. As a result, the content and assessment structures of this course may change for 2018 entry. We therefore recommend that you check this course page before finalising your application and after submitting it as we will aim to update this page as soon as any changes are ratified by the College.

Professional accreditation

This course is professionally accredited by IET (Institution of Engineering and Technology) and BCS (the Chartered Institute for IT).

Achieving a professionally accredited degree demonstrates to employers that you have achieved an industry-recognised standard of competency.

Like our MEng degrees, our BEng degree counts towards the educational requirements for becoming a Chartered Engineer (CEng). A CEng is a highly respected qualification earned by professionals working in engineering, which can lead to higher earning potential and better career prospects. It also brings international recognition of your qualification, which is particularly useful for students preparing for a career abroad.

While our MEng degrees fully satisfy the educational requirements of this professional qualification, BEng graduates will need to undertake further study on graduation to demonstrate that their knowledge is at Master's degree level.

All applicants for CEng status will also need to demonstrate their ability to meet competences described in the Engineering Council's UK-SPEC.

Our professional accreditation agreements with BCS and IET are renewed every five years, and our current agreement is due to be renewed for students beginning this course from the 2017–18 academic year.


As well as your main Imperial degree, you will also receive the award of the Associateship of the City and Guilds of London Institute (ACGI) on completion of this course.

The City and Guilds of London Institute is one of three historic Colleges that came together to form Imperial College London in 1907.

Find out more about our Associateships.

Some applicants may be set lower offers and some more challenging ones. It is the College’s policy to not make offers below three A’s at A-level in relevant subjects, 38 IB points with at least a grade 6 at higher level in relevant subjects, or their equivalent.

A typical range of offers made by this Department in 2016 (encompassing at least 85% of applicants who studied A-level or IB) is shown above.

Post-application open day and interview

If your UCAS application indicates that you are likely to satisfy our requirements and you live within reasonable travelling distance of the College you will be invited for an interview. This enables us to get an impression of your motivation, your suitability for the course and your potential for success in an engineering career. Equally importantly, it gives you a chance to find out more about the courses and about Imperial in general.

All applicants will also be asked to complete an online admissions test.

The interview day consists of:

  • a welcome presentation from the Admissions Tutor and Director of Undergraduate Studies
  • a guided tour of the facilities at the Department and College
  • demonstrations of undergraduate projects
  • a 1-1 interview with one of our lecturers

If you are unable to attend an interview day, the Department will organise a Skype interview.

English language qualifications (all applicants)

For admission to this course, you must achieve the standard College requirement in the appropriate English language qualification. For details of the minimum grades required to achieve this requirement, please see the English language requirements for undergraduate applicants.

Academic Technology Approval Scheme (ATAS)

An ATAS certificate is not required for overseas students who apply for this course.

For more information about the Academic Technology Approval Scheme (ATAS), please see the International Student Support website.

Tuition fees and funding

We charge tuition fees for every year that your course lasts. The fee you will be charged is based on your fee status, which is determined by government regulations.

Tuition fees (Home and EU students)

2018 entry
£9,250 per year

The above fee applies to the academic year 2018–19 only.

The fee for Home/EU students is controlled by the UK government.

Please note that the fee you pay may increase annually by an amount linked to inflation and approved by Parliament under the Student Fees (Inflation Index) Regulations 2006 – currently the measure of inflation used is the RPIX.

Government funding

If you're a Home student, you can apply for a Tuition Fee Loan from the UK government to cover the entire cost of tuition for every year of your course.

You can also apply for a means-tested Maintenance Loan to help towards your living costs.

EU students

The UK government has confirmed that funding arrangements for EU students starting a course in 2018 means they will continue to pay the Home rate of tuition and have access to the Tuition Fee Loan for the duration of their course.

This will remain the case even if their course finishes after the UK's exit from the European Union.

Tuition fees (Overseas and Islands students)

2018 entry
£29,000 per year

The tuition fees for Overseas and Islands students are set by Imperial College London.

You should expect and budget for your tuition fee increasing each year by an inflationary amount. The measure of inflation used will be the Retail Price Index (RPI) value in the April of the calendar year in which the academic session starts e.g. the RPI value in April 2019 will apply to fees for the academic year 2019–2020.

Accommodation and living costs

Living costs, including accommodation, are not included in your tuition fees.

Over 90 per cent of Imperial undergraduates choose to live in our halls of residence in their first year. You can compare costs across our different accommodation options on our Accommodation website.

A rough guide to what you might expect to spend to live in reasonable comfort in London is available on our Fees and Funding website.
