Can You Take Modules Outside Your Department?

The answer is: it depends enormously on your university, your department, and your programme. That's not a hedge — it's the reality of how UK universities structure optional module provision. Some programmes actively encourage cross-department study. Others prohibit it entirely. Most fall somewhere in between, with rules that aren't obviously documented anywhere.

Here's how the system actually works.

The three categories of universities

UK universities handle cross-faculty module access in one of three ways.

Open elective systems. Some universities — particularly civic redbricks and newer universities — operate genuinely open elective systems where students can take a defined number of credits from anywhere in the institution. You might be a history student taking a data science module, or an engineering student doing a language course. The elective slots are built into the degree structure. This is the most flexible arrangement and is particularly common at universities that have invested in interdisciplinary curriculum design.

Permitted cross-faculty modules. Many universities allow cross-faculty study but only from a prescribed list. Your economics department might have formal arrangements with the politics, law, or statistics departments to accept certain modules as optional credit. Outside that list, you're not permitted to cross. This is the most common arrangement at UK universities.

Closed systems. Some programmes — particularly professional degrees in medicine, dentistry, law, and some engineering programmes — operate entirely within their own faculty. All optional credit comes from within the department, and cross-faculty study isn't available. This is especially common where professional accreditation bodies specify what the curriculum must contain.

The only way to know which category your programme falls into is to check your programme specification and any associated optional module documentation from your department.

How to find out what's actually permitted

Your first port of call is the module specification or programme handbook. Every UK university is required to publish these, and they should specify whether optional credits can come from other faculties and, if so, what the constraints are.

If the documentation is unclear — and it often is — contact your personal tutor or department administrator directly. Ask specifically:

• Am I permitted to take optional modules from outside the department?
• If so, how many credits are available for this?
• Do I need formal approval, or can I select them directly through the module portal?
• Are there any prerequisites or level restrictions that apply?

The last question matters. Many departments will allow you to take modules from other faculties, but only at a compatible level. A second-year student typically can't take a final-year module from another department without special approval.

The strategic case for cross-faculty modules

Beyond whether it's permitted, there's a question of whether it's worth doing. The answer depends on your goals.

Broadening career-relevant skills. This is where cross-faculty modules make their strongest case. An economics student adding a data science or programming module develops skills that have genuine market value and that aren't available within a pure economics curriculum. A history student adding a psychology or communications module builds transferable skills for roles in policy, media, or public affairs.

Grade distribution considerations. Modules from other departments can have different grade distribution profiles than modules within your own faculty. A marketing student who takes a psychology module may find the grade distribution in that module more favourable than their home-department options — or less so. Without data, this is guesswork. GradeHack holds FOI-sourced grade distributions for modules across multiple UK universities, which can help you assess specific cross-faculty options.

Meeting degree requirements flexibly. Some programme structures allow you to use cross-faculty modules to fulfil breadth requirements. If your degree requires a certain number of credits outside your core specialisation, cross-faculty modules can be the mechanism for meeting that requirement without picking up a weak module from the edge of your home department's offering.

Intellectual interest. Not everything needs a strategic justification. If you're a computer scientist who wants to take a module on the history of science, that's a legitimate choice. The caveat is to understand how the module is assessed and whether the format suits your strengths before you pick it purely on interest.

The risks of cross-faculty modules

Cross-faculty study carries specific risks worth understanding before you commit.

Assessment format mismatch. Modules from other faculties are often assessed very differently from your home department. An engineer taking a sociology module might find the assessment is entirely essay-based, which requires a different kind of preparation. If your writing isn't strong, an essay-heavy module from another department is a risk. How assessment type affects your performance is worth understanding before you pick.

Contact hours and scheduling. Cross-faculty modules are scheduled independently of your home department. Timetable clashes are common and aren't always resolvable. Check the scheduled times before you select.

Support and assumed context. Lectures and seminars in other departments assume a shared background that you may not have. A statistics module taken by a literature student may lack the conceptual foundation the lecturer assumes. This isn't insurmountable, but it requires more independent effort to catch up on assumed knowledge.

Administrative complexity. Cross-faculty registrations sometimes fall through administrative gaps. Confirm your registration directly with both departments. Don't assume a selection in the portal means you're enrolled — follow up in the first week of term.

What to do if you want to study outside your department

If cross-faculty study is permitted in your programme, the process is usually:

1. Identify the module you want and confirm it's available to students from your faculty.
2. Check there are no prerequisite courses you haven't taken.
3. Confirm the timetable doesn't clash with anything you're already committed to.
4. Submit the selection through the module portal, or request formal approval if required.
5. Follow up with the target department to confirm your registration.

If cross-faculty study isn't formally permitted but you're keen to pursue it, speak to your personal tutor. Some departments will make exceptions for strong academic cases, particularly for final-year students whose research interests don't fit neatly within the home department's offering.
