When Is London Mayor Election 2026

Right, let’s cut through the fog of London. You’ve seen the posters peeling off the Tube station walls, you’ve heard the faint sound of a megaphone in the distance. You’re wondering, when exactly do we get to vote for the next person to boss around Sadiq Khan? The short answer is Thursday, 7 May 2026. Mark it in your phone, tattoo it on your arm, or just remember it’s the day your daydreams about a functioning Tube might finally get a new champion.

Yes, that’s right—2026. Not 2024, not 2025, but the year we’ll all pretend to be very engaged in local politics again. It feels like an eternity, but the London mayoral election is a fixed four-year cycle, like the Olympics but with fewer medals and more arguments about ULEZ. The last one was in 2024, so the next one is exactly two years after that, like a recurring nightmare you actually look forward to.

Now, you might be thinking, “Why can’t they just hold it next week? I’ve got strong opinions about the congestion charge!” Well, calm down, you passionate urban warrior. The date is set by law—the Greater London Authority Act 1999, to be precise. It’s always the first Thursday in May, which is conveniently the same day as local council elections, so you can vote for your local bin managers and the person who pretends to care about the Northern line all in one go. Efficiency!

Who’s running? (Or, The Art of Speculation)

Right now, in the cold, dark winter of 2025, we don’t know the full list. It’s like a celebrity marriage: everyone is talking, but nobody knows who’s actually committed. Sadiq Khan is almost certainly running for a third term, because why stop now when you can still find new ways to annoy the suburban SUV drivers? The Conservatives will likely pick someone who promises to “get tough” on something, probably knife crime, potholes, or the price of a pint in Zone 2.

But here’s the juicy bit: the surprising fact that will make you the star of your next pub quiz. The last time a London mayor was re-elected after just one term was… never. Ken Livingstone served two terms, Boris Johnson served two terms, and now Sadiq Khan is gunning for his third. So if history is any guide, the next election is less a contest and more a coronation, unless someone invents a time machine and brings back a giant fox skeleton.

The Liberal Democrats will put forward someone who is incredibly competent and whom you will forget within 48 hours of the result. The Greens will probably have a candidate who proposes to replace all black cabs with electric recumbent bicycles. And then there will be the actual indie candidates—the ones who promise to ban pigeons or introduce a free croissant for every commuter. You’ll laugh, but that croissant guy might get 4,000 votes.

The Day Itself: What to Expect

On 7 May 2026, you will shuffle to your local polling station—probably a draughty church hall or a primary school that smells of stale biscuit. You’ll get a ballot paper the size of a small tablecloth. You’ll have two votes: one for your first-choice candidate and one for your second-choice. This is called the Supplementary Vote system, which is basically political speed-dating: if your top pick gets knocked out, your second choice gets a shot. It’s surprisingly romantic for something involving city hall.

Do you have to vote? No. But if you don’t, you forfeit the right to complain about the pothole on your street that looks like the Grand Canyon. Also, there’s a weird bylaw in the GLA Act that says if turnout drops below 30%, the winner must ride the entire Hammersmith & City line in a pantomime horse costume. (I made that last bit up, but it should be true.)

The results usually come in around midnight on Friday, 8 May. You can stay up, drink cheap wine, and watch the count on a live stream hosted by someone who really loves spreadsheets. The winner will give a speech thanking their “incredible team,” their “amazing family,” and “the good people of London, especially those who didn’t vote for me—I’ll win you over.” You’ll groan, but deep down, you’ll feel a tiny spark of civic duty.

Why It Matters (Besides the Obvious)

Look, the London mayor controls a lot of stuff: the Tube, the buses, the police (partly), housing policy, and the congestion charge. That means whoever wins in 2026 will decide if your commute costs £15 or £20 or if you have to swim to work because they’ve pedestrianised the Thames. It’s a big job, and they get a snazzy office in City Hall, which is currently shaped like a glass egg. Fancy.

Here’s a truly surprising fact: the London mayor has less power than the mayor of Paris or New York, but more power than the Queen. Technically, the Queen can’t order a bus to turn left. The mayor can. So take that, monarchy. In 2026, you get to choose who holds that bus-rending power.

So, until then, keep an eye on the news, ignore the early polls (they’re always wrong), and start practising your “I was this close to voting for the Croissant Party” story. The countdown to Thursday, 7 May 2026 is on. You’ve got exactly one year and a bit to decide if you want a mayor who’s a bit of a plonker or a mayor who’s a complete plonker. See you at the ballot box!

P.S. If you’re a non-Brit, please don’t move to London just to vote. We have enough problems. And if you’re a pigeon, you can’t vote either. Sorry.
