UK University Open Days 2026: What to Pre-Book, What to Walk Up, and How to Email the Department
5 min read Article Updated 2026-05-27
Most prospective students walk into a UK uni open day, hit a queue, do one subject talk, and walk out feeling rushed. The day works for them in inverse proportion to how much they planned it. Three things make the difference: knowing which sessions to book the moment registration opens, knowing which ones to walk up to instead, and knowing what to do when the session for your course is "fully booked".
Below: the open day calendar for seven major UK universities for the rest of 2026, the three buckets you actually want, and a short template for emailing a school directly when the subject session you needed is full.
The 2026 open day calendar (verified today)
Seven universities, ordered with Oxford first because it's the unusual case that proves the booking rule. Dates and booking patterns checked against each university's open day page this week.
| University | Open day dates | Booking pattern |
|---|---|---|
| Oxford | 1 and 2 July, 18 September | Drop-in by default; a few sessions need advance booking |
| Imperial | 12 and 13 June | Booking essential; a virtual open day is also offered |
| Bristol | 12 and 13 June, 31 October | Booking essential; subject sessions fill fast |
| Warwick | 20 and 27 June, 10 and 24 October | Booking essential; opens roughly eight weeks before each date |
| UCL | 26 and 27 June | Booking essential; UCL asks you to pick one of the two days, not both |
| KCL | 27 June, 11 July, 12 September, 17 October | Booking essential; four chances across the year |
| LSE | Spring date already passed; autumn date to be announced | Register your interest first, then book when you get the invite |
For any university not in this list, the pattern is almost always the Warwick one: booking essential, and the booking window opens six to eight weeks before the day. Set a reminder for the date booking opens, not for the open day itself.
One thing the table cannot show: at almost every booked-out university, the headline subject sessions for competitive courses (medicine, dentistry, veterinary science, popular law and computer science programmes) book out in hours, not days, the moment the window opens. If you're applying for a competitive course, treat booking-opening day like an application deadline.
The three buckets: pre-book, walk-up, and email-the-department
The honest version of an open day is two layers. The university markets it as a single thing you book. In practice it's a registered main day with sub-sessions that fall into three buckets, and most prospective students only ever do the first one.
Pre-book (do these the moment booking opens)
Subject talks. Accommodation tours at the popular halls. Live Q&A panels with current students. Subject-specific lab tours, mock-tutorials at Oxbridge, applicant taster sessions at the more selective London courses. These have small capacity, they fill in hours at competitive courses, and they're the ones you'll regret missing.
The work to do beforehand: pick one subject session for your top course, one accommodation tour for the hall you'd actually want to live in, and one panel that lines up with a worry you have (cost of living, course workload, year-abroad logistics, whatever it is). Three booked things is enough for one day.
Walk-up (don't waste a booked slot on these)
General campus tours that run on rotation throughout the day. Department and library information stalls. The course-overview stands in the main marquee. Students' Union info points. The "where to live in this city" stalls. These have plenty of capacity and they run continuously, so a booked slot would only get in their way.
The trick is to book a single high-value session for your top course (a 90-minute slot is typical) and then walk up to four or five secondary things in the gaps. A walked-up campus tour an hour after your subject talk is more useful than a second booked session, because you've got a frame of reference for the questions to ask the tour guide.
Email the department directly (the move readers don't know about)
If your subject session is full and the next open day is past the date you need to decide, email the school's undergraduate admissions contact directly. Most schools will accommodate a smaller subject taster, a one-to-one with a current student, or a "standing at the back" seat at the talk that's officially full. Smaller post-92 schools respond fastest. The most over-subscribed Russell Group departments respond least often, but more often than you'd expect for the polite ask.
The email template
Use this 7 to 14 days before the open day, not on the day. The school-level admissions email usually follows the pattern admissions-<school>@<uni>.ac.uk or ug-admissions@<school>.<uni>.ac.uk. If that bounces, the central admissions team will route the message.
Subject: Open day [date], [Course name], is there flexibility if the subject session is full?
Dear [School name] admissions team,
I'm planning to attend the [date] open day to look at [course]. The subject session is showing as fully booked. I'd really like to hear from a current student or attend a smaller version of the session if there's any option. I'm an offer-holder / current Year 12 / mature applicant [pick one] and the open day is the only chance I have to visit before [the deadline you're working to].
Is there anything you'd suggest?
Thanks,
[Your name]
Be specific about why you need flexibility. Deadline pressure is honest leverage. Name what you'd swap for, so the school doesn't have to guess. The replies that come back are often short ("Yes, come along and we'll fit you in") but they're the difference between a useful visit and a wasted one.
What to actually do on the day
Arrive at the welcome point about thirty minutes before your first booked session, not at the headline start time. The first hour is when the queues are worst and the orientation desks are most useful. Pick up the printed programme and a campus map even if you've got the app; cross-referencing on paper is faster.
Between booked sessions, eat lunch in the part of campus where the course you're applying for is taught, not at the central marquee. The food is usually worse, but you'll see the building you'd actually be in. Ask the current students you bump into one specific question: not "do you like it here?" but "what would you have wanted to know before you started?"
Take five minutes at the end of the day to write down three things while they're fresh: what surprised you, what worried you, and one question you didn't get to ask. That note is what makes the second open day (because you should aim to do at least two before you firm) useful instead of repetitive.
Bottom line
Open days reward planning. Book the moment booking opens. Use the pre-book slots for the things that have small capacity. Walk up everything else. If the session you needed is full, email the department a week before the day with a polite, specific ask. The schools that say yes are the ones you wanted to hear from anyway.
