Imperial College London
This guide covers four departments — Chemistry, Chemical Engineering, Materials, and Bioengineering — at Imperial College London, ranked #2 in the world (QS 2026). Written for students applying with A-levels from international schools for 2026–27 entry.
The table below merges every department's two largest routes by application volume into one view, 2023 → 2024 UCAS cycles, with RATE = Offers ÷ Applications and a year-on-year Change column. Programme names are colour-coded by department (see legend) — Chemical Engineering runs only one undergraduate route, so it appears once. Tab 2 covers every remaining sub-programme; Tab 3 explains what's academically different between them.
Reading this table: RATE = Offers ÷ Applications, used consistently across every tab on this page — Tabs 2 and 3 no longer use a separate "Success Rate" metric, to avoid the two numbers being confused for each other. Our most recent complete UCAS cycle is 2024; Imperial's published admissions statistics currently run 2020–2024.
Worth a decision: by application volume, Molecular Bioengineering — not Biomedical Technology Ventures — is Bioengineering's second-largest route, so it's shown above. It's smaller than Biomedical Engineering, but its offer rate ran higher in both 2023 and 2024, not lower — see Tab 3. Swap in Biomedical Technology Ventures here if you'd rather keep strict alignment with the Biosciences guide's existing scope.

Selectivity Spectrum
Offer Rate here = Offers ÷ Applications, pooled across 2020–2024 for stability (small cohorts swing a lot year to year) — the same metric as Tab 1, just covering every route instead of the top two. Bars share a 0–80% scale across all four departments.

single-route dept
Chemical Engineering runs one admissions line — MEng, ESAT-gated, 46.5% five-year offer rate (4,216 apps → 1,960 offers over 2020–24; 979 apps → 428 offers in 2024 alone). There's no internal comparison to make here: that figure is the genuine odds, with no easier side-door through a sibling programme, unlike every other department on this page.

+ Management (BEng) ran around a tiny base earlier in the period and shows zero applicants in 2024 — looks discontinued, worth verifying with the department. Same direction as Chemistry: every 4-year MEng route, specialist or not, has a higher offer rate than the 3-year BEng — the extra year keeps filtering out everyone who isn't sure yet.

Bioengineering is the most internally consistent department here — its three routes sit within 17 points of each other. Biomedical Technology Ventures only has two admissions cycles of data (launched 2023), so treat its figure as provisional.
Headline: Chemistry still has the widest internal spread (2.1×, Management vs. Research Abroad) of any department here, but under Offer Rate the gap between departments is much smaller than it first looked — Materials (1.8×) and Bioengineering (1.3×) aren't far behind. Bioengineering, despite covering three genuinely different programmes, remains the most evenly matched.

Programme Differences
Each department's largest, default route — described in full, exactly as before — followed by how every sibling route differs from it.
Chemistry
BSc · 3 years · Faculty of Natural Sciences · UCAS: F100
Major ProgrammeInterviewHigh Competition
What is it?
Explores atoms, molecules and reactions — from quantum chemistry and thermodynamics to organic synthesis and spectroscopy. The department's largest and default route: 704 applications in 2024, more than every other Chemistry route combined with room to spare. Years one and two are identical across all six Chemistry routes below, so switching later is straightforward.
What you'll study

★ 51% of 2024 entrants held A*A*A*+; 85% held A*A*A or above. Overseas offers: 120 (2020) → 202 (2024).
How the other five routes differ from the BSc
MSci32.9% → 55.6%
One extra year, same entry grades, same first two years. Adds a substantially bigger final-year research project and more advanced, research-led modules. The offer-rate jump isn't about the work being easier — applicants who go straight for the 4-year code already know they want the research-heavy path, so it's a smaller, more self-selected pool.
+ Medicinal Chemistry33.9%
Same MSci structure, co-taught by chemistry lecturers and pharmaceutical-industry experts, aimed at drug discovery. The one specialist track that does not get easier than the BSc — its rate sits right alongside it.
+ Molecular Physics49.4%
Same MSci structure, co-taught with Mathematics and Physics instead. Well above the BSc and Medicinal Chemistry, sitting closer to the placement-based routes below.
+ Year in Industry / + Research Abroad55–58%
A paid industry placement, or an ~8-month placement at a partner university overseas, added onto the MSci. Both run above even the plain MSci's rate — a longer, more specific commitment narrows the pool to people who are already sure.
+ Management28.2%
Keeps the BSc's three years, swaps the final-year chemistry specialisation for a year in the Business School. By far the smallest applicant pool of any Chemistry route — yet consistently the most selective, every year for five years running.
Chemical Engineering

★ Most demanding entry — ESAT + interview. 64% of 2024 entrants held A*A*A*+. Applications grew from 754 (2020) to 979 (2024).
How the other routes differ
There aren't any46.5%
The only department on this page with no sibling routes at all. The 46.5% five-year offer rate is the genuine odds for anyone applying — there's no easier specialist side-door the way there is in Chemistry or Materials.
Materials Science & Engineering
BEng · 3 years · Faculty of Engineering · UCAS: JF52
Major ProgrammeInterviewHigh Competition
What is it?
Studies the structure, properties and applications of materials — metals, ceramics, polymers and biomaterials — and how to design new ones. The largest of the department's four active routes (391 applications in 2024). The first two years are shared with every other Materials route, so the BEng is the natural default if you're not yet committed to a specialism.
What you'll study
Structure & properties of materials
Computational modelling
Materials design & characterisation
Group & individual project work
Career paths
Materials / R&D engineer
Aerospace & defence
Biomedical devices
Renewable energy sector
★ Most accessible grade profile of the four departments — ~20% of entrants held AAA, the floor minimum. Typical offer is A*AA, not A*A*A as sometimes quoted — confirm against the department's own apply page.
How the other three routes differ from the BEng
MEng32.8% → 59.5%
One extra year, Master's-level elective modules and an individual research project added to the same BEng foundation. Same pattern as Chemistry's BSc → MSci step: the 4-year code draws a smaller, more committed pool and is easier to get an offer on than the BEng, despite identical entry grades.
+ Nuclear Engineering40.7%
Same MEng structure, specialised toward nuclear materials and engineering. Sits between the plain MEng and the BEng — easier than the BEng, but not quite as accessible as the unspecialised MEng.
Biomaterials & Tissue Engineering34.5%
A separate MEng specialised toward biomedical-facing materials — bone regeneration, implants, tissue scaffolds. Still easier than the BEng, though the closest of the three MEng routes to it.
+ Managementdiscontinued?
Existed earlier in 2020–24 but shows zero applicants in the latest cycle — looks discontinued. Worth checking with the department before presenting it as a live option.
Biomedical Engineering
MEng · 4 years · Faculty of Engineering · UCAS: H161
Major ProgrammeInterviewModerately Competitive
What is it?
A "top-down" engineering route into medicine and biology — mechanics, imaging, prosthetics, medical devices, physiological monitoring. By far the largest and most established route in the department — 709 applications in 2024, more than the other two routes combined — and the one most applicants mean when they say "Bioengineering at Imperial."
What you'll study
Biomedical signals & imaging
Biomechanics & tissue engineering
Medical device design
Physiology for engineers
Career paths
Medical devices R&D
Clinical engineer
Health technology entrepreneur
Academic research / PhD
★ Highest offer rate of the four departments (48.1%) and largest overseas offer volume (341 in 2024, up from 154 in 2020).
How the other two routes differ from Biomedical Engineering
Molecular Bioengineering53.4% → 70.0%
Not a duration variant but a genuinely different academic identity — "bottom-up" engineering of biological systems at the molecular and cellular level, rather than top-down devices and mechanics. Smaller than Biomedical Engineering (930 vs. 3,036 applications over five years) — but its offer rate is the highest in the department, not the lowest. If another page on this site calls it "more competitive" than Biomedical Engineering, this data says otherwise.
Biomedical Technology Ventures58.2%
Keeps Biomedical Engineering's core foundation but swaps a meaningful slice of engineering content for entrepreneurship and business, run jointly with the Business School, including a startup internship. Launched 2023, so only two admissions cycles exist — treat its rate as provisional. Sits between Biomedical Engineering and Molecular Bioengineering.
