What's On in London
Sunday 20 September 2026 · This weekend · City guide
Sunday 20 September has that rare, golden quality where the city feels simultaneously laid-back and alive — the kind of day you step outside meaning to grab a coffee and end up somewhere completely wonderful. From sun-dappled jazz brunches in Kingston to a late-evening indie music discovery in east London, there is a thread of something brilliant running through every hour. Lace up, tune in, and let London do its thing.
Highlights

Alice Milburn Sunday Jazz — There are few finer ways to ease into a Sunday than with live jazz and something good in your glass, and Alice Milburn's session at Ex Cellar Kingston from 11:00am promises exactly that kind of mellow, soul-warming magic. The intimate cellar setting gives it a gorgeous underground-club cosiness, and Milburn's warm, assured vocals are the kind that make strangers at neighbouring tables smile at each other. At £22, it is a proper treat that feels worth every penny.

Law Society RFC Festival of Sport — If your Sunday needs fresh air, good company, and the satisfying thud of a rugby ball, the Law Society RFC Festival of Sport at Richmond Athletic Ground from 11:00am is a full-on celebration of everything that makes grassroots sport great. Set against the backdrop of one of London's most storied sports grounds, it is a day-long affair that mixes competition with community in the best possible way. At £180 this is clearly a participation event rather than a spectator ticket, so come ready to get stuck in.

Open Age Early Session — Rollernation's Open Age Early Session from 12:00pm is a flat-out joy of a concept — roller skating for adults, free from the chaos of little ones, set inside one of London's most vibrant rinks. Whether you last laced up a pair of skates in 1987 or last weekend, the welcome here is warm and the floor is yours. At £15, it is one of the most fun and genuinely feel-good things you could do with a Sunday afternoon.

Open Age Late Session — If the early skate sells out or you simply need a longer lie-in, Rollernation rolls out a second Open Age session at 3:00pm — same brilliant concept, same inclusive, adults-only atmosphere, same £15 entry. The afternoon light, the music pumping through the rink, and the gradual rediscovery of your own balance make this something between a workout, a laugh, and a small personal triumph. Do not underestimate how much you will want to come back.

Settima, Lucifer Sky, Cariad, Lilliput Moss, Anon Dred — As the weekend draws to a close, Endeavour offers something genuinely exciting for anyone who loves discovering new music before the rest of the world catches up — five acts sharing a stage from 6:00pm in what promises to be a crackling, varied evening of live sound. Names like Lucifer Sky and Anon Dred suggest something with edges and atmosphere, while a line-up this broad hints at a night that will shift moods and surprise you more than once. At just £10, this is the kind of grassroots gig that reminds you why live music in London is still one of the greatest things on earth.
