London Theatre July 2026: Complete What's On Guide

What July Looks Like

The rhythm of a London theatre July is set by the calendar: the school summer holidays begin in the last week of the month, and producers programme their family shows to land exactly then. This year the family offer is unusually strong — three significant new productions open for the holidays, joining a bench of long-running favourites that already do this better than almost anywhere in the world.

The most useful way to read this month, then, is by who you are booking for. If you are bringing children, the choice is genuinely excellent and we would start there. If you are after an evening out, a run of sharp comedies and continuing hits carries you through to September. Below is our honest take, grouped that way — families first.

The Best Family Shows This Summer

If June conversion taught us anything, it is that the family outing — booked for a group, chosen with care — is the summer booking that matters most. Here is where we would put that decision this July.

Dog Man: The Musical — Queen Elizabeth Hall, Southbank Centre Family

This is the family show we would book first for the summer holidays. Based on Dav Pilkey's worldwide-bestselling graphic novels — from the creator of Captain Underpants — Dog Man: The Musical brings the part-dog, part-policeman, all-hero crime-fighter to the stage in a fast, funny, hour-and-a-quarter adventure with no interval. Best friends George and Harold race to finish their musical before lunchtime, while Dog Man tries to stop Flippy the cyborg fish and outwit Petey, the world's most evil cat.

It plays a strictly limited run at the Queen Elizabeth Hall on the Southbank from 29 July to 16 August — right at the start of the holidays — and at roughly 75 minutes it is well judged for younger attention spans. Recommended for ages 5 and up. This is the one to move on early, because a three-week window during the holidays fills fast.

Brainiac Live — London & on tour Family

Winner of the 2025 Olivier Award for Best Family Show, Brainiac Live is the UK's original high-energy science spectacular — liquid-nitrogen clouds, vortex smoke rings, exploding hydrogen balloons and a great deal of controlled chaos, all watched safely from your seat. It is loud, fast and genuinely thrilling for children, with just enough real science underneath the bangs to count as a day out that teaches something.

It returns for the 2026 summer holidays in London and across the country. Recommended for ages 5 and up, with loud bangs and flashing lights throughout — worth knowing if you are bringing very young or sound-sensitive children. See our page for the current venues and dates.

Cats — Regent's Park Open Air Theatre Musical

Andrew Lloyd Webber's Cats returns in a brand-new production directed and choreographed by Drew McOnie, Regent's Park's Artistic Director — its first major staging in a decade, and its first outdoors. Based on T.S. Eliot's Old Possum's Book of Practical Cats and built around the famous score, from Memory to Macavity, this is a big, spectacular summer musical staged under the open sky, which is a large part of its appeal for a family evening.

It plays Regent's Park Open Air Theatre for seven weeks only, from 25 July to 12 September 2026, before a UK and Ireland tour from October. As an open-air show, it is worth checking the weather and bringing layers. See our page for booking and tour dates.

Still the Best of the Family Bench

Three new openings are the headline, but London's standing family shows are the reason it leads the world for this, and several are perfectly placed for the holidays.

The Tiger Who Came to Tea at the Theatre Royal Haymarket remains the West End's most reliable first-theatre trip — 55 minutes, ideal for ages 3 to 8, and exceptional value, running through to 5 September. My Neighbour Totoro at the Gillian Lynne Theatre, the RSC's six-time Olivier-winning Studio Ghibli adaptation, is the more ambitious choice for slightly older children (ages 6 and up) and plays to 30 August. Paddington the Musical at the Savoy, with music and lyrics by Tom Fletcher, is the newest of the big family musicals and booking well into 2027.

And the giants are all still standing: The Lion King at the Lyceum, Wicked at the Apollo Victoria, and Matilda The Musical at the Cambridge — the three you book when you want a guaranteed West End occasion for a mixed-age group.

One more for the diary, with a very tight window: Bluey's Big Play, the Olivier-nominated stage show built around the beloved Blue Heeler family, plays New Wimbledon Theatre from 28 July to 2 August — six days only, and aimed squarely at the youngest theatregoers. If Bluey is a fixture in your house, move quickly.

Grown-Up Nights Out

If the children are not part of the plan, July and the weeks just after it are strong for a classic London evening — two new comedies open, and the summer's best plays keep running.

The Comedy About Spies — Adelphi Theatre Comedy

Winner of Best New Play at the 2026 WhatsOnStage Awards and an Olivier nominee, Mischief's The Comedy About Spies returns to the West End for a strictly limited eight-week run after a sold-out 2025 season. From the team behind The Play That Goes Wrong, it is a 1960s spy caper of stolen weapon plans, rival CIA and KGB agents converging on a London hotel, mistaken identities and immaculately timed chaos. The Guardian called it a "delightfully silly show" on its first run — the kind of evening you leave grinning.

It plays the Adelphi from 1 August to 26 September 2026, running around two hours and twenty minutes including an interval, recommended for ages 10 and up. A strong, uncomplicated choice for a group who want to laugh.

How the Other Half Loves — The Old Vic Comedy

Alan Ayckbourn's 1969 comedy — three couples, one affair, and an escalating tangle of misunderstandings — gets a new production directed by Phillip Breen, staged in the round for which the play was originally written. Roger Allam and Dorothy Atkinson lead as Frank and Fiona Foster, joined by Ayesha Antoine, Laura Elsworthy, Adam Gillen and Rowan Polonski. It is part of Matthew Warchus's final season at the Old Vic, and Ayckbourn remains one of the great architects of comic mechanism — the misunderstandings here are engineered with real precision.

Previews begin 29 July, with the run continuing to 19 September and press night on 11 August. Recommended for ages 12 and up.

Still Running: The Summer's Best Plays

Arcadia at the Duke of York's is the one we would not let pass — Tom Stoppard's greatest play in Carrie Cracknell's acclaimed revival, running to 12 September. The Truth at the Apollo is the reliable classic night: Florian Zeller's sharp comedy of honesty and affairs, 90 minutes with no interval, running to 12 September. Sinatra The Musical at the Aldwych, the world-premiere jukebox biography built around the big-band songbook, continues its long run. And if you move quickly, the all-female Glengarry Glen Ross at the Old Vic — Indira Varma and Rosa Salazar leading Mamet in the round — plays its final performances, closing 18 July.

Coming Up: On Sale Now

Looking further ahead, Jesus Christ Superstar is on sale now for its upcoming tour — Andrew Lloyd Webber and Tim Rice's rock opera, with tickets from £20.80. Worth booking early if it is on your list; see our page for dates and venues.

Also on Our Radar: Booking Direct

As ever, a few of the summer's most talked-about productions are not available through our booking partners — we can't sell you tickets, but they are worth knowing about. Regent's Park Open Air Theatre's wider summer season and the National Theatre's programme both carry notable work this July; for anything not linked above, book directly with the venue. We include shows here on editorial merit, not because of any commercial relationship — and if a show isn't worth your money, we will say so.
