6 Sustainable Summer Swaps for a Greener British Summer

Summer in the UK means picnics in the park, days at the coast, and — if you’re not careful — a lot of single-use plastic. Over the past few summers I’ve slowly swapped out the usual disposable kit for options that last longer, cost less over time, and don’t leave a trail of packaging behind. None of these are expensive “eco investment” purchases; they’re small, practical swaps that pay for themselves by the second or third use.

Here are six worth making this year.

1. A Reusable Water Bottle

A decent insulated stainless steel bottle keeps drinks cold for hours in the sun and cuts out the need for single-use plastic bottles on hot days out. It’s one of the simplest reusable drinkware upgrades you can make, and a good one will outlast a whole season of festivals, beach days and school runs. Hydro Flask and Klean Kanteen are the two most reliable options if you want something genuinely built to last rather than a novelty that dents after a month.

2. Reef-Safe Sunscreen

Protecting your skin matters, but plenty of high-street sunscreens contain chemicals — oxybenzone and octinoxate among them — that are known to damage coral reefs and marine life once they wash off in the sea. Reef-safe, mineral-based sunscreens give the same protection without that trade-off, and they’re increasingly easy to find through UK stockists rather than needing to be imported.

3. Sustainable Swimwear

If you’re due a new swimsuit this year, it’s worth looking at swimwear made from recycled nylon rather than virgin synthetic fabric. It sits alongside the rest of an eco-friendly wardrobe approach — buying fewer, better-made pieces rather than restocking every season. Summersalt and Vitamin A are two brands doing this well, with genuinely wearable, well-fitted designs rather than eco-swimwear that looks the part but doesn’t perform.

4. Bamboo Sunglasses

Plastic sunglasses frames can take centuries to break down once they’re binned. Bamboo frames biodegrade, and they’ve come a long way from the slightly clunky early designs — brands like Woodzee and Panda Sunglasses now make frames that hold their own style-wise against anything on the high street.

5. Organic Cotton Beach Towels

Conventional cotton is one of the most chemically intensive crops grown, using large amounts of pesticides and water. Organic cotton is grown without those inputs, which makes for a softer, more absorbent towel and a lighter footprint. Coyuchi and Sand Cloud both make organic beach towels worth the slightly higher price tag — they last years longer than the thin, fast-fashion versions that fray after a couple of washes.

6. Biodegradable Picnic Supplies

Disposable plates and cutlery are a picnic staple, but the plastic versions sit in landfill indefinitely. Compostable alternatives made from bamboo, cornstarch or sugarcane break down naturally instead, which makes them a straightforward fit for a sustainable hosting approach to outdoor entertaining. Repurpose and Biocean both offer ranges that decompose properly rather than just being labelled “eco” without the substance behind it — worth checking for compostable certification rather than taking the packaging’s word for it. Pair them with safer food storage options at home and the plastic-free approach carries through from picnic to pantry.

The takeaway

None of these swaps require an overhaul of how you spend your summer — just a slightly different choice at the point of buying. Start with whichever feels most useful for how you actually spend your summer (the water bottle is the easiest first step for most households), and build from there. It fits the same logic as any of the everyday household swaps worth making around the home: small, durable changes beat one big gesture that doesn’t stick.
