NUS research consistently finds that close to 90% of UK students say they’re unfamiliar with what their students’ union officers actually do — even though every student is automatically a member. The SU is the most under-used institution in student life.
Key Takeaways:
- Do I have to join the students’ union? No — you’re enrolled automatically when you join your university. There’s no separate application or fee. Every student is a paid-up member by default, and you can opt out, though very few students do (and it removes your vote).
- Is the students’ union the same as the university? No. The SU is a separate, usually charitable, student-led organisation. The university funds it but it is constitutionally independent, which lets it represent students — sometimes by challenging the university itself.
- What’s the difference between a course rep and a sabbatical officer? A course rep is an unpaid, part-time role you do alongside your degree, representing classmates. A sabbatical officer is elected by the whole student body to run the union full-time for a year, paid a salary, and usually a charity trustee.
Almost every student in the UK is a member of an organisation they could not really describe. You were enrolled into your students’ union the day you joined your university, you have probably walked past its building a hundred times, and there is a reasonable chance you have spent money in its bar — and yet, surveys suggest, the large majority of students say they do not actually know what their union does or who runs it. That is a strange situation for something you are already a paid-up member of.
This guide fixes that. It explains what a students’ union actually is, what it does for you whether or not you ever get involved, how it is run, and every route into it — from the thirty seconds it takes to vote, up to running for a full-time paid role. It is written both for the student who just wants to finally understand the thing, and for the student wondering whether to stand for election. A lot of what the union does runs through societies and clubs, and getting involved is one of the most reliable ways of making friends at university, so those guides sit alongside this one.
What is a students’ union?
A students’ union — often shortened to “SU”, or called a guild or association at some institutions — is an organisation that exists to represent students and improve their experience at university. The key thing to understand is that it is yours, not the university’s.
An independent, student-led charity
Your students’ union is a separate organisation from your university. It is usually a registered charity, it is led by students, and it has its own staff, its own budget, and its own decision-making structures. The university funds it, and the two work closely together, but the union is constitutionally independent — which is the entire point. Its job is to represent students’ interests, and sometimes that means agreeing with the university and sometimes it means challenging it. An organisation that was simply part of the university could not do that credibly.
Automatic membership: you’re already in
You do not apply to join your students’ union and you do not pay a separate fee for membership. Every student at the institution is automatically a member from the moment they enrol. (In England and Wales there is a legal right to opt out of union membership, but very few students do, and opting out does not save you money — it just removes your vote.) Practically speaking: you are in, the membership is free, and the question is not whether to join but whether to use what you are already part of.
The SU vs the university: who does what
The clearest way to understand the union is to see it next to the university.
| Area | Your university | Your students’ union |
|---|---|---|
| Teaching, exams, your degree | Responsible | Represents you if something goes wrong |
| Formal complaints & appeals | Runs the process | Advises and supports you through it |
| Societies, clubs & activities | Provides some space/funding | Runs and supports them |
| Welfare & wellbeing | Provides counselling, support services | Runs an independent advice service |
| Housing | Some halls; limited private-housing help | Independent housing advice |
| Academic discipline | Runs the process | Represents and supports you |
| Bars, shops, social spaces | Some | Often runs its own venues |
| Student voice & representation | Listens (and is lobbied) | Gathers it and speaks for students |
The pattern is simple: the university delivers your education and the services around it; the union represents you within that system and runs the parts of student life that work best when students run them.
What your students’ union actually does for you
Most of what follows happens whether or not you ever attend a meeting. This is the part worth knowing even if you never plan to “get involved.”
Representation and advocacy
The union’s core job is to be the collective voice of students. It gathers what students think — through course reps, surveys, councils and elections — and uses it to push for change with the university and beyond. In practice this ranges from the small and concrete to the large and structural: extending library opening hours during exams, changing how a course is assessed, improving a building, responding to a fees or funding issue. It also represents students at the level above the individual university, often through national bodies. You benefit from this constantly without seeing it, in the same way you benefit from a lot of representation you never personally attend.
The advice service: academic, housing, money and discipline support
This is the single most underused thing most unions offer. Students’ unions typically run an advice service that is free, confidential, and — crucially — independent of the university. It is staffed by people whose job is to be on your side. They can help with academic problems (appeals, complaints, extensions and academic misconduct cases), with housing (contract problems, deposits, disputes with landlords), with money worries, and with university disciplinary processes. If something goes seriously wrong during your degree, the union advice service is one of the first places you should go — and a lot of students only discover it exists after the moment they needed it.
Societies, clubs and activities
The part of student life most visible to new students — the societies and clubs, the freshers fair, much of the sport — is run through the union. The union provides the funding framework, the room bookings, the insurance, and the training for the students who run each group. When you join a society, you are already participating in your union.
Bars, shops, events and spaces
Many unions run their own commercial spaces: a bar, a café, a shop, a venue for club nights and gigs. These are not just conveniences — the profit from them is typically reinvested into the union’s services and activities. Union venues are also usually the cheapest social spaces on or near campus, which makes them relevant to anyone watching their budget, and they are a significant part of student nightlife.
| SU service | What it helps with | How to access it |
|---|---|---|
| Advice service | Appeals, complaints, housing, money, discipline | Drop-in or appointment; free, confidential |
| Representation | Course and university-level issues | Through your course rep / SU officers |
| Societies & clubs | Hobbies, interests, sport, friends | Freshers fair, refreshers fair, year-round |
| Union venues | Cheap socialising, events, club nights | Just turn up |
| Volunteering | Experience, community, skills | Union volunteering team |
| Elections & democracy | Choosing who represents you | Vote each year; stand if you want |
How your students’ union is run
The union’s democratic structure looks more complicated than it is. Strip it back and there are three layers: the people elected to lead it, the people elected to represent specific groups, and the meetings where decisions get made.
Sabbatical officers: the elected, paid, full-time roles
At the top are the sabbatical officers — usually shortened to “sabbs.” These are students, elected by the whole student body, who take a year out of study (or stay on for a year after graduating) to run the union full-time. They are paid a salary for the year, typically in the region of £17,000–£21,000 depending on the union and location, and they are usually also trustees of the union as a charity, which gives them real legal responsibility. There are normally several of them, each with a brief — a president, plus officers for areas like education, welfare, activities, and sport. They are, in effect, the union’s elected leadership for that year.
Course reps and part-time officers
Below the sabbatical officers sits a much larger layer of part-time roles. Course representatives — usually just “course reps” — are students who represent their classmates on a particular course or in a particular department, gathering feedback and raising it with staff. The role is unpaid and you do it alongside your degree; the time commitment is small. Many unions also have part-time officers for specific communities or campaigns, again unpaid and done alongside study. This layer is the union’s main day-to-day connection to ordinary students.
Union Council, referendums and how decisions get made
The union’s policy — its official positions and priorities — is set democratically. Most unions have a council or similar body, made up of elected students, that meets through the year to debate and pass policy. Bigger questions can go to a referendum of all students. Any member can usually submit an idea or a motion. The exact machinery varies between unions, but the principle is consistent: the union’s positions are meant to come from students, through a process students can take part in.
How SU elections work
Once a year — usually in spring — the union holds elections for the next year’s sabbatical officers and many of the part-time roles. Any member can stand; any member can vote. Campaigns run for a week or two, voting is done online, and the results are announced at a results night. The elections are the single biggest formal moment of student democracy in the year, and, as the next sections discuss, they are also where the engagement problem is most visible.
[Detailed national data on students’ union elections — turnout, candidate numbers, trends — is published each year by the National Union of Students in its survey of unions, which is a useful external reference point for how engaged students across the UK actually are.]
Ways to get involved: the ladder
“Getting involved in the SU” sounds like one thing, but it is really a ladder of options with very different levels of commitment. You can step on at the bottom and never go higher, and that is completely fine — the bottom rung still matters.
Low-commitment: vote, give feedback, use the services
The lowest rung costs you almost nothing and is genuinely worthwhile. Vote in the annual elections — it takes a couple of minutes online and it is the most direct say you get over who represents you. Respond to union surveys when they come round. Tell your course rep when something about your course is not working. And actually use the services you are paying for, especially the advice service. None of this requires you to “be an SU person.” It is just using your membership.
Medium: become a course rep, volunteer, join a campaign
The middle rung is where you start contributing rather than just consuming. Becoming a course rep is the most common entry point — it is a small time commitment, it looks good, and it genuinely helps the people on your course. Volunteering through the union, joining a campaign you care about, or helping run a society all sit on this rung too. The defining feature of the middle rung is that it is meaningful but it does not take over your life or your degree.
High: run for a part-time or sabbatical officer role
The top rung is standing for election — for a part-time officer role alongside your studies, or for a full-time sabbatical role. This is a serious commitment, especially a sabbatical year, which is a full-time job. It is also, for the right person, one of the most formative things you can do at university. You do not have to be the obvious “student politician” type to do it well; unions are generally keen for a wider range of students to stand than currently do.
| Rung | Option | Time commitment | What you get out of it |
|---|---|---|---|
| Low | Vote, give feedback, use services | Minutes | A say; support when you need it |
| Low–Medium | Become a course rep | An hour or two a term | Influence; a CV line; useful contacts |
| Medium | Volunteer, join a campaign, run a society | A few hours a month | Experience, friends, skills |
| High | Part-time officer | Significant, alongside study | Leadership experience, real responsibility |
| High | Sabbatical officer | Full-time for a year | A paid leadership role; major experience |
You can also move up the ladder over time — plenty of sabbatical officers started as a course rep in first year.
Course rep and officer roles, honestly
The advice to “get involved” tends to skip the honest detail of what these roles are actually like. Here it is.
What being a course rep is really like
Being a course rep is mostly low-key. You gather feedback from your coursemates — sometimes informally, sometimes in meetings — and you raise it with staff at things like staff–student committee meetings. Some terms there is a lot to raise; some terms there is very little. The role rewards being organised and being willing to speak up in a room with staff in it. It is not glamorous, but it is real: course reps are the reason a lot of small, sensible changes to courses actually happen. And it is genuinely useful on a CV because it is concrete evidence of representing other people and communicating with an institution.
What a sabbatical year involves
A sabbatical year is a full-time job. You are running part of a charity, you have a brief to deliver, you sit in a lot of meetings with senior university staff, you represent students publicly, and you are — usually — a charity trustee with the legal responsibility that carries. It is paid, it is a year long, and it is demanding. People who have done it tend to describe it as one of the hardest and one of the best things they have done. It is not a soft option or an easy way to delay graduating.
The career value: what it signals to employers
Both roles, at their own scale, signal things employers actively look for. A course rep role is communication, representation and a bit of diplomacy. A sabbatical role is leadership, budget responsibility, public-facing communication, and managing competing interests — which is why former sabbatical officers often find the year opens doors. If you are thinking about how university experience translates into work, this connects directly to graduate jobs, careers and internships.
The honest downsides
It would be dishonest to only give the upsides. Course rep work can feel thankless in a quiet term when nobody gives you feedback. A sabbatical year means stepping out of your studies and out of your normal student life for a year, which is a real disruption, and the job can be stressful and politically exposed in a way student life usually is not. Union politics can also be frustrating — change is slow, and not every campaign succeeds. None of this is a reason not to do it. It is a reason to go in with your eyes open.
Why it’s worth caring, even though turnout is low
There is an awkward fact at the centre of student unions, and pretending it away helps nobody.
The low-turnout problem
Turnout in students’ union elections is low. The national average has sat at roughly 16–17% in recent years — meaning the people who run your union, and set its priorities, are typically chosen by around one in six students. Alongside that, surveys have found that close to 90% of students say they are unfamiliar with what their union’s officers actually do. So the situation is: an organisation everyone is a member of, run by people most members did not vote for and could not name.
What low engagement actually costs students
This is not just a democratic tidiness problem. Low engagement has real costs. It means the union’s positions are shaped by a small, self-selecting slice of the student body, which makes them less representative. It makes it easier for the university to discount what the union says — “you only speak for a sixth of students” is a genuine line of argument. And it means a lot of students never find the advice service, the support, and the influence they are entitled to, simply because they never engaged enough to know it was there. The cost of disengagement is mostly invisible, which is exactly why it persists.
Small actions that genuinely make a difference
The encouraging part is that the bar to making a difference is very low — because engagement is low. In an election decided by a small turnout, one more vote is proportionally worth a lot. A course rep role that nobody else stood for is yours for the taking. A motion to council, a campaign idea, a piece of feedback — these land more easily in a system most students ignore than they would in a crowded one. You do not have to become a full-time student politician. Voting, repping, and using the union you are already part of are small actions, and in a low-engagement system, small actions count.
Conclusion
A students’ union is not a building, a bar, or a vague idea — it is an independent, student-led organisation that you are already a member of, that represents you whether you notice or not, and that runs a set of services and activities you have already paid for. Understanding it is worthwhile on its own. Using it is better: vote in the elections, tell your course rep when something is wrong, and remember the advice service exists before the moment you need it. And if you want to go further, the ladder is right there — course rep, volunteer, officer — and because so few students climb it, every rung is more reachable than it looks.
The easiest first step is the smallest one: next time your union holds an election, spend the two minutes it takes to vote. You are paying for a say. Use it.
To go further, societies and clubs covers the most popular way students get involved, and the social life hub brings the rest of this part of student life together in one place.
Frequently asked questions
Do I have to join the students’ union?
You are enrolled automatically when you join your university — there is no separate application or fee. In England and Wales you have a legal right to opt out of membership, but very few students do, it saves you no money, and it removes your vote.
Is the students’ union the same as the university?
No. The union is a separate, usually charitable, student-led organisation. The university funds it and the two work closely together, but the union is constitutionally independent so it can represent students’ interests, including by challenging the university when needed.
What’s the difference between a course rep and a sabbatical officer?
A course rep is an unpaid, part-time role you do alongside your degree, representing your coursemates. A sabbatical officer is elected by the whole student body to run the union full-time for a year, is paid a salary, and is usually a charity trustee.
Do sabbatical officers get paid?
Yes. Sabbatical officer roles are full-time and salaried — typically somewhere around £17,000–£21,000 for the year, depending on the union and location.
How do I vote in SU elections?
Elections are usually held once a year, in spring, with online voting open for a set period. As an automatic member you are eligible to vote — watch for the announcement from your union and follow the link when voting opens.
Can I get involved without running for anything?
Absolutely. Voting, responding to surveys, giving feedback to your course rep, volunteering, and joining a society are all ways of being involved that do not require standing for election.
What is the NUS, and how does it relate to my SU?
The National Union of Students is a confederation of students’ unions across the UK that represents students at a national level and provides services to member unions. Your local students’ union may or may not be affiliated to it; either way, your day-to-day union experience is mostly local.
