Six weeks off school starts late July 2026, and if you're the one on kid duty for even a few of those days, you need a plan that doesn't involve overthinking it. Here's the rundown of free museums, splash spots and low-cost days out across London that'll actually keep the kids entertained — and won't wreck your weekend budget.
When Do the London Summer Holidays 2026 Actually Start?
Most London state schools break up between Tuesday 21 and Thursday 23 July 2026, back in early September. It shifts slightly by borough and school type — academies and some faith schools run their own calendar — so check your kid's actual school if you're planning time off work around it. Either way, that's roughly six weeks of holiday to fill, which is a decent stretch to actually explore parts of London you normally just commute past. If you're sharing childcare or splitting days with a partner or grandparent, sort the calendar out now rather than in week four when everyone's run out of ideas.
Best Free Days Out With the Kids This Summer
London's free museums do a lot of heavy lifting here, and they work whatever the forecast throws at you. The Science Museum in South Kensington has proper hands-on stuff kids get stuck into for hours, the Natural History Museum next door covers dinosaurs and anything that bites, and Young V&A in Bethnal Green is built for younger kids specifically, sandpit and finger-skateboard park included. The British Museum runs a Families Desk at weekends and school holidays with trails and activity packs if you want a bit of structure to the visit. For something more outdoors, Brent Lodge Park in Ealing has a free arboreal maze and a wooden viewing tower, and there are free playgrounds scattered across nearly every borough for burning off energy between stops. Browse baby and toddler classes for holiday drop-ins if you've got a younger one who needs something more structured.
Where to Cool the Kids Down When It's Hot
Royal Docks Summer Splash is back at Royal Victoria Dock — lifeguard-supervised open water swimming, sandpits, deckchairs, all free. Good shout if your kids are confident swimmers; younger ones can just dig around in the sand while you keep an eye on the older ones in the water. Paddling pools open across London parks once it warms up, including Victoria Park (Tower Hamlets) and Ruskin Park (Lambeth) — worth checking your council's site for exact opening dates before you turn up. Weekday morning swim sessions at local leisure centres are generally quieter than weekends if you're trying to avoid the crowds. Check cafes and venues for spots nearby with space for buggies and decent coffee, because a splash session followed by a flat white is a solid morning.
Budget-Friendly Activities That Don't Feel Like a Compromise
Minigolf by Craig & Karl at Montgomery Square in Canary Wharf is free to play all summer, clubs and balls handed out by stewards on the day — works for toddlers who just want to whack a ball and older kids who actually keep score. The National Maritime Museum in Greenwich runs free storytelling and craft sessions through the holidays, no booking needed, which is handy for a wet-weather backup plan. Library summer reading challenges are free, run by the local council, and genuinely keep early readers motivated without you having to nag. For something more structured, search kids activities for holiday clubs running near you — a couple of full days a week gives everyone a breather.
How to Actually Get Through Six Weeks Without Losing the Plot
Some structure helps more than you'd think, especially with younger kids. One outing, one quieter activity — museum in the morning, park or garden after lunch, works better than trying to cram in a full day every day. Booking a holiday club or two a week, even half-days, spreads the load if you're juggling work around childcare. If sleep or behaviour goes sideways with the routine change, health and wellbeing and services for parents list sleep consultants and family support who deal with exactly this during the holidays.
Quick Tips for Surviving the Summer Holidays
- Book big attractions online ahead of time, even the free ones — timed slots fill up fast in the school holidays.
- Pack for the day: sun cream, spare clothes, snacks, a phone charger, and a portable fan if you're doing the tube in the heat.
- Mix free days with one or two paid extras a week rather than blowing the budget in week one.
- Check your borough's website for paddling pool and splash park opening dates — they change year to year.
- Buggy on the tube? Plan a step-free route in advance using TfL's step-free guide, it'll save you a fight with the stairs.
