Summer Admissions Test Preparation for the ESAT, TMUA and LNAT

The ESAT, TMUA and LNAT are three separate admissions tests run on two separate calendars, and a candidate applying with more than one of them has to reconcile the two by hand. UAT-UK's account window opens 1 June 2026, its October test week runs 12-16 October 2026, and the LNAT's own booking cut-off for Oxford and Cambridge falls a month earlier, on 15 September 2026, with a 15 October 2026 sit-by date landing inside that same test week.

Most guides to these tests explain what is on them. This page does something narrower and, for a candidate juggling two admissions cycles at once, more useful: it lays the two organisations' own published dates end to end, in the order they actually fall, so the gaps and the collisions are visible before they become a missed deadline. Every date below is taken directly from UAT-UK's key dates page and the LNAT's dates and deadlines page, both checked on 21 August 2026, and stated with the year and the specific sitting it applies to.

1 June 2026: UAT-UK Opens Its Account While the LNAT Stays Shut

UAT-UK's cycle begins first. Account creation, requests for access arrangements and bursary applications for all 2027-entry candidates open on 1 June 2026 at 3pm BST, and nothing on the LNAT side opens until UAT-UK's own test booking has already been running for several weeks. For a candidate who needs a separate room, extra time or a reader in either test, this six-to-seven-week head start matters: access arrangements have to be approved before a test can be booked, and approval takes UAT-UK up to ten working days to process. There is no equivalent early window on the LNAT calendar to make use of in this period, so a candidate sitting both should use these weeks to clear the UAT-UK request first, since the LNAT profile cannot even be created until August.

This is also the point to settle which UAT-UK test actually applies. Most engineering, natural sciences and computer science courses that use UAT-UK require the ESAT, while courses built around mathematical reasoning - maths, economics, some computer science routes - more often require the TMUA. Oxford also runs the TARA for a smaller group of non-STEM courses, on the same UAT-UK calendar as the ESAT and TMUA. Which one a given course needs is published on that university's own course page, not inferred from the subject name, and it is worth checking before requesting access arrangements for the wrong test.

20 July - 31 July 2026: UAT-UK Booking Opens, Five Weeks Before Anyone Can Touch the LNAT

Test booking for the October 2026 UAT-UK sitting opens on 20 July 2026 at 3pm BST. A test costs £78 for candidates sitting in the UK or the Republic of Ireland and £133 for candidates sitting elsewhere - a genuine third-party cost, distinct from any tutoring, that a family budgeting for two tests in one cycle needs to plan for twice if both an ESAT or TMUA sitting and an LNAT sitting are required. UAT-UK's own advice is to book as early as possible, since a candidate who waits risks losing their nearest Pearson VUE test centre to an earlier booker rather than to the deadline itself.

The five-week gap between this date and the LNAT's own opening on 1 August is not a quiet period. It is the window in which a candidate who has already secured an ESAT or TMUA slot should turn to preparing their UCAS course list, because the next fixed date - the LNAT's own registration opening - starts a second, faster-moving calendar that overlaps the first one almost immediately.

1 August - 14 September 2026: The LNAT Opens and the First UAT-UK Cut-Off Lands

LNAT registration and UCAS registration both open on 1 August 2026, and LNAT testing itself begins a month later, on 1 September 2026. A candidate can sit the LNAT before or after submitting their UCAS form, so the two systems are not strictly sequential - but the LNAT's own site states plainly that a test sat before the 2026 summer holiday will not count for this cycle, which rules out any attempt to get ahead of the calendar by testing early.

Six weeks after the LNAT opens, the first UAT-UK deadline of the autumn arrives: the cut-off for requesting access arrangements for the October 2026 sitting is 14 September 2026 at 6pm BST. Anyone who missed the June opening for this request now has one week left before it closes - and, as the next section shows, that same week also carries the LNAT's own first hard deadline, one day later. A candidate preparing for the LNAT alongside a UAT-UK test should treat this fortnight as the busiest paperwork stretch of the whole cycle, not the test weeks themselves.

15 - 28 September 2026: The LNAT's Oxbridge Register-By Date Beats the UAT-UK Bursary and Booking Deadlines

This is the fortnight that catches families off guard, because the LNAT's earliest deadline is not its sitting date - it is the date by which the test slot must be booked. Candidates applying to Oxford or Cambridge must register and book their LNAT test slot by 15 September 2026 in order to guarantee a sitting before or on 15 October 2026. That register-by date sits a full month ahead of the actual sit-by date, which trips up applicants who assume, reasonably from the UAT-UK side of the calendar, that a test's booking deadline sits close to the test itself.

Six days later, on 21 September 2026 at 6pm BST, UAT-UK's own bursary application deadline for the October sitting closes. A week after that, on 28 September 2026 at 6pm BST, UAT-UK's test booking closes altogether, and the organisation is explicit that it cannot accept a booking made after that time. Read together, the sequence for a dual applicant runs: LNAT booked by 15 September, UAT-UK bursary requested by 21 September, UAT-UK test booked by 28 September - three deadlines in a fortnight, on two different websites, for two different tests.

5 - 16 October 2026: What Happens When Test Week Collides With the UCAS Deadline?

UAT-UK's January-cycle access arrangements and bursary applications reopen on 5 October 2026 at 3pm BST - a full week before the October test window even starts, which is easy to miss while attention is on the immediate sitting. That sitting, UAT-UK's Test Window 1, runs 12-16 October 2026, with all three tests available on every day of the window for candidates everywhere except China, Hong Kong and Macau, which run a restricted sub-schedule across the same five days.

This is the week the two calendars actually meet. The UCAS deadline for Oxford, Cambridge and other early-deadline courses is 6pm on 15 October 2026 - a date that falls inside the UAT-UK test window itself, and the same date by which the LNAT must already have been sat for an Oxford or Cambridge application. Oxford's own admissions pages make the ESAT requirement unambiguous: every Physics applicant, for example, must take the test as three modules - Mathematics 1, Mathematics 2 and Physics - and the university's published test-dates table for 2027 entry matches UAT-UK's own to the day. A candidate reading a course requirement that mentions ESAT format or checking what score a university expects from the LNAT should do that reading well before this week arrives, because by 12-16 October the only task left is sitting the tests and submitting the form - there is no time in this window to still be researching what either test covers.

For a candidate applying to, say, a Cambridge economics course requiring the TMUA and a law course at the same university requiring the LNAT, this week is the whole point of planning backwards from it: the LNAT sitting has to be finished by 15 October, the TMUA has to be sat somewhere inside 12-16 October, and the UCAS form covering both applications is due by 6pm on 15 October. None of those three dates moves to accommodate the others.

26 October - 21 December 2026: Results, a Second UAT-UK Booking Window, and the KCL/LSE/UCL Cut-Off

Results from the October UAT-UK sitting reach candidate accounts on 16 November 2026 - a month after the test window closes, and, notably, after the UCAS deadline that the test was needed for. A university only receives a UAT-UK score if the candidate has applied to a course that lists the test as a requirement, so results arrive as confirmation of an application already submitted, not as an input to it.

UAT-UK's January 2027 booking window opens on 26 October 2026 at 3pm GMT, giving candidates who missed October, or who are applying to a course with a January admissions deadline, a second route in. Three further deadlines follow before the year ends: access arrangements requests for the January sitting close on 7 December 2026 at 6pm GMT, bursary requests close on 14 December 2026 at 6pm GMT, and booking itself closes on 21 December 2026 at 6pm GMT. On the LNAT side, the same period carries one deadline of its own: candidates applying to King's College London, the London School of Economics or UCL must sit the LNAT before or on 31 December 2026, a full ten weeks after the Oxbridge sit-by date and comfortably clear of the UAT-UK January booking window that opens around the same time.

4 January - 8 February 2027: Can You Still Sit If You Missed October?

UAT-UK's Test Window 2 runs 4-8 January 2027, on the same all-countries-except-China/Hong Kong/Macau basis as the October window. This sitting is not available to most Oxford or Cambridge applicants - the exceptions are mature candidates applying to a mature college with a January deadline at Cambridge, and applicants to Oxford's Astrophoria Foundation Year - so for the great majority of candidates this window exists only because their target course does not set an October-only deadline.

The LNAT's January deadlines split by university in a way nothing else on either calendar does. Candidates applying to Bristol or Durham must register, submit their UCAS form and sit the LNAT all by the same date, 13 January 2027 - the tightest single cut-off on the whole calendar. Every other LNAT university, aside from Oxford, Cambridge, King's College London, LSE, UCL, Bristol and Durham, allows more room: register and book by 20 January 2027, submit UCAS by 6pm on 13 January 2027, and sit the test by 25 January 2027. UAT-UK results from the January sitting follow on 8 February 2027, closing out a calendar that, for a candidate who registered for UAT-UK access arrangements back on 1 June 2026, runs for just over eight months.
