Cambridge Chemical Engineering & Biotechnology: At a Glance
The Cambridge Chemical Engineering and Biotechnology course offers a unique integration of two key scientific disciplines: chemical engineering and biotechnology.
Chemical engineers focus on transforming raw materials into valuable products, while biotechnology leverages living systems and organisms to create new solutions. The Cambridge Chemical Engineering and Biotechnology course offers a uniquely interdisciplinary approach to these disciplines, designed to equip students with the tools needed to solve real world problems, such as creating sustainable food and water supplies, cleaner energy, and renewable plastics.
In the first year, students build a strong foundation in engineering design, chemistry, and practical skills through lectures and hands-on lab work, as well as small group supervisions. By the second year, you’ll have the opportunity to dive deeper into specialised areas such as biotechnology, process thermodynamics, and fluid mechanics. In the third year, students undertake a major design project, applying their knowledge to real-world problems, with further research options in your final year.
The course places a strong emphasis on the essential transferable skills needed to drive innovation. The four year course is accredited by the Institution of Chemical Engineers and ensures all graduates can go on to make a positive impact in their careers.
The Cambridge Chemical Engineering and Biotechnology course is a unique offering. It’s really important you use your personal statement to show the admissions tutors that the course is exactly what you are interested in studying. Not Chemistry. Not Engineering. Not Biotechnology. Not Life Sciences. So, why Chemical Engineering and Biotechnology?
You’ll certainly encounter the question at interview but it’s important that before you even write your personal statement, you have an answer to this question as it should help guide and structure your Chemical engineering personal statement. Make sure you have a really good understanding of what Chemical Engineering and Biotechnology actually is and encompasses. These online resources can help you get a better sense of the subject:
The Cambridge Chemical Engineering and Biotechnology Department: Take a look at the research interests of departmental staff to get a sense of the kind of projects and scope of Chemical Engineering and Biotechnology. They also have some short videos introducing their research. Look for further reading opportunities if you find one topic particularly interesting!
IChemE: IChemE has a great series of videos and articles which introduce Chemical Engineering and help you understand what Chemical Engineers do. This is a great starting overview.
Cambridge Chemical Engineering & Biotechnology Entry Requirements
If you are applying for Chemical Engineering and Biotechnology at the University of Cambridge for 2027 entry, you will need strong predicted grades, the right A-Level or IB subjects, the Engineering and Science Admissions Test (ESAT) and, if shortlisted, a strong performance at interview.

Applicants must also take the ESAT View our full guide to the ESAT, here
Competition is high: in the 2025 admissions cycle, Cambridge receive approximately 7 applications per place, with 77 applicants accepted.
Cambridge Chemical Engineering ESAT
Do You Need the ESAT for Cambridge Chemical Engineering?
Yes. Applicants to Cambridge Chemical Engineering and Biotechnology for 2027 entry are required to take the Engineering and Science Admissions Test (ESAT).
The ESAT is designed to assess the mathematical and scientific problem-solving skills needed for demanding undergraduate courses at universities including Cambridge.
Which ESAT Modules Do Chemical Engineering Applicants Take?
Cambridge Chemical Engineering and Biotechnology applicants take:
Mathematics 1
plus two modules chosen from:
Biology
Chemistry
Physics
Mathematics 2
Each module lasts 40 minutes, meaning applicants complete 120 minutes of testing in total.
Choosing your two additional modules strategically is important. You should consider both your A-level subjects and the areas in which you are strongest at solving unfamiliar problems under time pressure.
When Is the ESAT for 2027 Cambridge Entry?
For students applying to Cambridge for 2027 entry, the relevant ESAT sitting takes place from 12–16 October 2026.
This falls immediately before Cambridge’s 15 October 2026 UCAS deadline, making it important to begin preparing well in advance rather than leaving ESAT practice until your application is submitted.
Always check the official Cambridge and UAT-UK guidance before registering, as test arrangements and deadlines can change.
How Should You Prepare for the Cambridge Chemical Engineering ESAT?
Effective ESAT preparation is about more than revising A-level content.
The test assesses whether you can apply familiar mathematical and scientific principles to unfamiliar problems accurately and under significant time pressure.
A strong preparation strategy should include:
Mastering the specification. Identify any gaps in the assumed mathematical and scientific knowledge before moving heavily into timed practice.
Practising unfamiliar problems. Avoid relying exclusively on standard A-level questions. You need to become comfortable deciding how to approach a problem rather than simply recognising a familiar question type.
Working under timed conditions. Forty minutes passes quickly, so speed and question selection become important.
Analysing your mistakes. Record whether errors are caused by missing knowledge, misreading questions, inefficient methods or time pressure.
Completing official preparation materials. These provide the closest indication of the style and level of reasoning expected in the real test.
Your goal should not simply be to complete as many questions as possible. You should become progressively more efficient at identifying the scientific or mathematical principle needed to solve each problem.

How to Write a Cambridge Chemical Engineering Personal Statement
Students applying in 2026 for 2027 university entry answer three structured questions rather than submitting the traditional single continuous personal statement.
Cambridge reads all three sections of your UCAS personal statement and recommends focusing primarily on academic detail.
For Chemical Engineering and Biotechnology, this is an opportunity to demonstrate not simply that you “love science”, but how you have explored your subject beyond the school curriculum and how your thinking has developed as a result.
Question 1: Why Do You Want to Study Chemical Engineering and Biotechnology?
Try to avoid answering this question with generic statements about how much you enjoy Chemistry or Maths!
Instead, consider which problems, ideas or applications have led you towards Chemical Engineering and Biotechnology specifically.
You might have become interested in:
sustainable energy
carbon capture
pharmaceutical production
biochemical engineering
industrial processes
materials
food and consumer-product manufacturing
renewable resources
biotechnology
process optimisation
The strongest answers explain how an initial interest led to further exploration.
For example, rather than simply saying that you read a book about renewable energy, discuss an idea you encountered, what you found interesting about it and the further questions it prompted.
This gives Cambridge evidence of academic curiosity, rather than simply a list of activities.
Question 2: How Have Your Studies Prepared You?
Your academic subjects provide an excellent opportunity to demonstrate the interdisciplinary thinking required for Chemical Engineering.
Think about connections between your subjects.
How has Mathematics helped you model or understand scientific processes?
How has Chemistry developed your understanding of reactions, thermodynamics or materials?
Has Physics changed the way you think about forces, energy or fluid behaviour?
Has Biology introduced you to biological systems that could be understood or manipulated through biotechnology?
You don't need to repeat information Cambridge can already see elsewhere in your application. Focus instead on what you have learned and how you think.
Question 3: What Have You Done Outside Education to Prepare?
For Cambridge, supercurricular activities are generally much more useful than simply listing extracurricular achievements.
Supercurricular activities are things you have done outside your normal curriculum to explore your academic subject.
These might include:
reading books or academic articles
attending lectures
completing online courses
entering science or mathematics competitions
undertaking independent projects
listening to relevant academic podcasts
attending university outreach programmes
relevant work experience
exploring a particular scientific question independently
Again, reflection matters more than quantity.
Three activities explored thoughtfully can tell an admissions tutor far more about you than a list of ten books, lectures and competitions.
Ask yourself:
What did I learn?
Did anything surprise me?
Did I disagree with anything?
What question did this lead me to investigate next?
That process demonstrates the kind of independent academic thinking Cambridge wants to see.
Once you do understand the subject, think about what it means to you. How would you define it? What excites you about it? These questions can guide your independent research and direct your preparation for your Cambridge Chemical engineering personal statement.
Cambridge want to see that you are genuinely excited about the subject and have taken time and steps to further explore it. That means looking at associated areas (e.g. energy, environment healthcare products, sustainability, risk and safety etc.) and having a broad understanding of an interest in the wide range of scientific disciplines it encompasses.
Some reading suggestions that you can dip in and out of to explore the breadth of Chemical Engineering and Biotechnology are:
Online resources:
The New Scientist (look for articles on Chemical Engineering and Biotechnology!)
Chemical Engineering resources (useful explanations of scientific principles!)
Books:
J Keeler & P Wothers, Why Chemical Reactions Happen, O.U.P.
PW Atkins, Molecules, Scientific American
Bondi, C, New Applications of Mathematics, Penguin
Hall, N (ed.), The New Scientist Guide to Chaos, Penguin
Baillie, C and Vanasupa, L, Navigating the Material World, Academic Press
As you read to gain a broad understanding of the subject, pay close attention to interdisciplinary links you can draw out in your personal statement and any other topics that interest you that you can go away and research further.
A really strong Cambridge Chemical Engineering personal statement will be able to show your interest in and understanding of the subject and an ability to engage with some of the interdisciplinary thinking and real world applications. Cambridge emphasise the power of the course to allow graduates to enact real positive change in the world so look for moments where Chemical Engineering and Biotechnology have created innovative solutions that inspire and excite you.
Tutors are also looking for you to showcase your curiosity and commitment to the Cambridge Chemical Engineering and Biotechnology course. A great way to do this is through co-curricular activities. These allow you to engage with the subject first hand, build your knowledge and demonstrate your creativity and innovative approach to problem-solving, qualities also strongly valued by Cambridge admissions tutors.

Boost your Cambridge Chemical Engineering Personal Statement
A great way to showcase curiosity for the Cambridge Chemical Engineering and Biotechnology course is by working with a tutor on an independent research project, diving into a topic of your own interest and honing your problem-solving and research skills. Students will work with tutors who are graduates from the Cambridge course to explore their research interests, answering questions such as: “Can biotechnology provide sustainable solutions for the global food crisis, or are the engineering challenges too complex?”
Working with a U2 Tuition tutor will push you to develop problem-solving skills and expand your Chemical Engineering and Biotechnology knowledge to impress admissions tutors and really stand out.
How to prepare for the Cambridge Chemical Engineering & Biotechnology Interview
The Cambridge Chemical Engineering Interview is the first moment you get to meet the admissions tutors and it’s the opportunity for your excitement for the course to really shine through.
You will normally have two interviews, each lasting around 20-25 minutes.
The interview questions you get asked will in part assess your motivation and in part your skills and aptitude. Be ready to expand on your Chemical engineering personal statement and on why you want to study the subject.
You should also be prepared for some practical questions in your Cambridge Chemical Engineering interview that are designed to test your problem-solving skills and maths and science knowledge. Make sure you have a strong understanding of order of magnitude (a key skill for engineers) and have broadened your knowledge of science beyond the A Level curriculum.
The Cambridge NRich programmes are a great way to boost your knowledge in preparation for the ESAT and the Cambridge Chemical engineering interview. They have programmes in Maths, Chemistry and Physics that will help enhance your skills beyond the level set at A Level.
A Cambridge interview is designed to test your aptitude for the subject and the supervision system. Being able to think flexibly is a key skill for Chemical Engineering students and something the interview format naturally tests. You will often be presented with new information in stages and tasked to process it and incorporate it into your argument. Don’t be afraid to change your mind if new information contradicts something you’ve just said. Show yourself to be an agile thinker who can quickly and intelligently respond to new information and use it to solve problems.
Cambridge Chemical Engineering Interview Days
