With temperatures soaring across the country, keeping the kids entertained over the school holidays without draining your bank account is a massive challenge. When it gets exceptionally hot outside, standard park trips can feel less like fun and more like an endurance test.

To help you survive the summer break with your budget and your sanity intact, we’ve rounded up the best low-cost, heatwave-friendly activities. These ideas span the country, accommodate everyone from toddlers to hard-to-please teenagers, and include plenty of brilliant ideas for staying cool at home.

Out and About: Staying Cool Across the Country

If you need to escape the house, the goal is to find air conditioning or natural shade. Thanks to national transport schemes running over the summer, family travel options are more affordable than ever, making cheap days out highly accessible.

1. The Cool Sanctuary of Museums & Galleries

Most national museums and art galleries offer free entry and, crucially, excellent air conditioning.

• For Littles & Middles: Head to regional interactive spaces like the Natural History Museum (London), the World Museum (Liverpool), or the National Museum of Scotland (Edinburgh). They have hands-on exhibits that keep younger minds busy in a climate-controlled environment.
• For Teenagers: Modern galleries like Tate Modern (London) or The Whitworth (Manchester) are great spots for older kids to wander. Many large museums also host free tech or art workshops specifically for teens during the holidays—check their local websites to book a free slot ahead of time.

2. Splash Zones and Outdoor Pools

When the heat peaks, water is the ultimate sanity-saver for parents.

• Splash Pads & Fountains: Many council parks feature free splash pads or fountains (like the public fountains at Granary Square in London or Science City in Bristol). Pack a towel, change of clothes, and plenty of sunscreen.
• Lidos and Outdoor Pools: If you are near the coast or areas with historic public pools, a family swim ticket is usually very budget-friendly. Look out for community-run outdoor pools which often offer heavily discounted family slots during heatwaves.

3. Forest and Woodland Canopies

Open fields are heat traps, but dense woodlands are naturally much cooler and provide great natural protection from ultraviolet rays.

• National trust sites, Forestry England, Forestry and Land Scotland, and Natural Resources Wales offer massive, deeply shaded trail networks perfect for walking.
• The Teen Angle: Turn a shaded walk into a competitive game of Geocaching (a free global digital treasure hunt using your phone’s GPS). It gives teenagers a purpose-driven reason to walk without feeling like they are on a boring family stroll.

At-Home Hacks: Keeping Cool and Entertained

When the midday sun is just too fierce, staying inside with the curtains drawn is the smartest move. Here is how to keep the peace at home without relying entirely on screens.

1. DIY Ice-Capades (Best for Younger Kids)

Water play doesn’t always have to happen outside. You can create brilliant sensory experiences right in the kitchen.

• The Frozen Toy Rescue: Freeze small plastic dinosaurs, coins, or toys inside plastic containers filled with water. Give your kids a spoonful of salt, a spray bottle of warm water, and some blunt tools (like plastic spoons) to “excavate” the toys. It keeps them cool and occupied for ages.
• Homemade Ice Lollies: Skip the pricey supermarket boxes. Blend leftover fruit, fruit juice, or yogurt, pour them into molds (or clean yogurt pots with a spoon for a stick), and freeze.

2. The Living Room “Chill-Out” Cinema

Turn the hottest part of the afternoon (usually 2 PM to 5 PM) into an official, low-energy cinema event.

Shut the blinds, turn off the lights, drag mattresses or duvets onto the floor, and set up fans safely. It keeps kids laying down and resting during peak temperatures rather than running around causing heat exhaustion.

The Teen Angle: Let your teenagers curate a film marathon (like Marvel, Harry Potter, or classic movie trilogies) or an indoor gaming tournament. If they are in charge of the schedule and setup, they are much more likely to happily engage.

3. Indoor Camping & Den Building

Building a classic blanket fort takes on a new meaning in a heatwave. Use lightweight bed sheets instead of heavy blankets and position a fan so it blows cool air directly inside the entrance. It creates a shaded, breezy micro-climate in the living room where kids can read, play on tablets, or nap comfortably.

Budget Projects Specially for Teenagers

Teenagers can be the hardest demographic to entertain on a budget, especially when they just want to retreat to their bedrooms. Here are three cheap ways to get them motivated and moving:
