sombr at The O2 2027: all five London dates, ticket availability and what fans need to know

One night at The O2 would already have been a fairly emphatic UK arena debut. sombr is now doing five.

The London run for his You Are The Reason Tour has expanded rapidly, with shows now scheduled across five nights in June 2027. Suki Waterhouse is listed as the special guest for the London dates.

For fans, the expansion is good news. It also makes the booking decision slightly more complicated. Five nights means five chances to get in, but also five chances to discover next spring that the date you bought no longer works.

Here is what is confirmed so far.

All five sombr O2 dates in 2027

The current London dates are:

• Monday 21 June 2027, The O2
• Tuesday 22 June 2027, The O2
• Thursday 24 June 2027, The O2
• Friday 25 June 2027, The O2
• Tuesday 29 June 2027, The O2

The fifth show on 29 June is the newest addition.

Ticketmaster now lists the later date alongside the existing O2 shows, while Stereoboard reported that it was added as a fifth and final London night following continued demand.

There is one small wrinkle worth knowing if you are checking several sources. At the time of writing, The O2's own event page still shows the earlier run ending on 25 June. Ticketmaster already lists 29 June, so the venue page appears not to have caught up with the newest addition yet.

Are sombr O2 tickets sold out?

Availability has been moving quickly.

When the fifth date was announced, Stereoboard reported that the previous four London shows had sold out. Ticketmaster currently shows low availability against several of the O2 dates, so it is better to check the live ticket page than rely on an older sold-out label.

That distinction matters with major arena shows. Extra production holds, returned tickets and other releases can sometimes change what appears to be available after the initial rush.

If the date you want currently looks unavailable, use the official ticketing pages rather than assuming a social media seller is your only option.

How did one London show become five?

The original announcement included a single London date as part of sombr's 2027 European arena tour.

That did not last long.

Extra O2 nights followed as demand built, eventually taking the London run to five shows. It is another sizeable step in a rise that included a major Reading and Leeds Festival appearance in 2026 and now leads into sombr's UK arena debut.

Five nights at the same arena also creates something slightly unusual for fans. You are not choosing between completely different legs of a tour. You are choosing between several versions of essentially the same London plan, separated by only a few days.

That is useful when tickets first go on sale. It can be awkward months later.

What if you bought the wrong sombr date?

Concert tickets increasingly go on sale a long way ahead of the actual show. June 2027 can look very straightforward from September 2026.

Then somebody books a holiday. Work dates move. A wedding appears. Your friends can suddenly do Tuesday but not Friday.

With five London shows, there is a decent chance that some fans eventually find themselves with the right artist, the right venue and the wrong night.

At the same time, somebody else may have exactly the reverse problem.

That is the sort of situation Swoppd is designed for. If one fan has tickets for 22 June but needs 25 June, while another has 25 June tickets and needs 22 June, Swoppd can help those fans find each other.

The important bit is what happens next.

Swoppd does not make a ticket transferable. A swap can only go ahead where the official ticket provider allows the relevant tickets to be legitimately transferred.

For tickets bought through The O2 or AXS, the venue says they use AXS Mobile ID. The O2 also advertises AXS Official Resale for eligible tickets.

That does not automatically confirm that every sombr ticket can be transferred between fans. Event-specific transfer functionality should be checked in AXS or with the relevant ticket provider before arranging a swap.

Where should you buy sombr tickets?

Start with the official channels.

The O2 says buyers using its website are directed to AXS, its official ticketing partner. Ticketmaster also has listings for the London shows.

Buying through an authorised source matters for more than simply avoiding scams. It tells you which provider actually issued your ticket, and that becomes important later if you need to check transfer, resale or entry rules.

The safest starting points are the official O2 event page and Ticketmaster's sombr listings.

If tickets appear unavailable, be particularly wary of strangers offering screenshots or asking you to move quickly because "someone else is interested". A screenshot is not the same thing as a legitimate transferable ticket.

Which O2 date should you choose?

If several nights are still available to you, there is no meaningful difference in venue. The question is simply which date is least likely to become a headache later.

The shows fall on a Monday, Tuesday, Thursday, Friday and another Tuesday.

The Friday night on 25 June may naturally be the easiest for people travelling into London without work the following morning. The weekday dates could be more useful if your weekends are already crowded or you are hoping to avoid the busiest travel periods.

The newest 29 June show also gives fans another option several days after the original run.

There is no clever trick here. Pick the date that genuinely works best rather than buying whatever appears first and assuming it can be fixed afterwards.

The short version

sombr is now scheduled to play five nights at The O2 in June 2027, on 21, 22, 24, 25 and 29 June.

Ticket availability has changed quickly as extra nights have been announced, so check the live authorised ticket pages for the latest position.

If you already have tickets and later realise another night works better, first check whether your specific tickets can officially be transferred. If transfer is permitted and another fan has the opposite date problem, that is where Swoppd can be useful.

Five nights gives London fans far more chances to see sombr. It also means "I've got the wrong date" could become a surprisingly common problem before June arrives.
