21 ultimate affordable sustainable swimwear brands UK 2024

As soon as spring hits, many of us can’t wait to begin our search for affordable sustainable swimwear. With new brands emerging that champion sustainability, it has never been easier to have the perfect beachside look that doesn’t contribute to beach pollution.

Eco friendly swimwear is becoming a hot topic in the fashion industry. A key driver of the projected $6.74 billion growth of the swimwear sector between 2020 and 2024, it seems sustainable swimwear is what everyone will be talking about this summer.

What is Sustainable Swimwear Made From?

Often made from synthetics derived from petrochemicals and coloured with toxic dyes, most conventional swimwear gets a failing grade for sustainability. Sustainable swimwear, often made from recycled or eco-friendly fibres, and crafted in fair supply chains, offers a low impact version of swimwear.

While there are lots of fabrics that make up the sustainable swimwear market, some common players include:

Econyl: A regenerated nylon made from ocean pollution, including discarded fishing nets, and landfill waste. This innovative fabric offers the same properties as virgin nylon without the environmental footprint.

Repreve: One of the world’s leading recycled fibres, Repreve has so far recycled more than 25 billion plastic bottles into material used for everything from swimwear to car interiors. This fantastic fibre is used by industry leaders such as Fitbit and Land’s End.

See our article for more on recycled polyester.

Affordable Sustainable Swimwear for the UK

This collection includes some of the hottest sustainable swimwear brands for every beachside holiday or relaxing poolside afternoon this summer.

However, it is important to note, sustainable clothes generally cost more to produce as workers are paid fairly and materials are carefully chosen. These sustainable styles are not the rock-bottom prices of fast fashion, but they are styles that won’t cost the earth.

Fast fashion brands that often have cheap swimwear styles have been left out of this list. While fast fashion may have cheap prices, they often don’t operate with the sustainable and ethical practices that reflect an industry that stands for fair supply chains and environmental protection.

However, as well as the brands listed here, we’ve made it really easy for you to be able to access sustainable fashion. See our article with some exclusive discounts for Good Maker Tales readers giving you money off some of our favourite brands.
