What Makes a Brand Sustainable?

Sustainable brands ensure their workers receive fair pay and work in safe conditions. They frequently collaborate with certified factories and follow strict ethical standards.

These brands focus on using organic, recycled, and even biodegradable materials as a preference. Eco-friendly materials include:

• Organic cotton
• Hemp
• TENCEL
• Recycled polyester

Reliable, eco-friendly firms are genuine about their supply chains and manufacturing methods. Certifications such as Fair Trade, GOTS, and OEKO-TEX demonstrate true dedication.

Sustainable brands work to reduce their environmental impact. They do the following:

• Use energy-efficient methods
• Minimise waste
• Take part in carbon offset programs

Best Sustainable Clothing Brands in the UK

If you are in the UK and prefer to shop locally, browse the top-rated, more sustainable clothing brands from the region. Here are the ten best sustainable clothing brands in the UK:

1. BEEN London

BEEN London was founded by former BBC journalist Genia Mineeva. This brand focuses on turning waste into luxury products. They follow a zero-waste approach by using materials that would otherwise go to landfills in East London. This includes:

• Tannery off-cut leather
• Recycled plastic bottles
• Innovative vegan options like apple skin leather.

Local artisans in East London handcraft each accessory. This helps cut down transport emissions and supports the local leatherworking industry.

BEEN London’s bags have a carbon footprint about 87% lower than similar bags from high-street brands.

To promote sustainability, they offer free repairs at their workshop and plant a tree for every purchase through their partnership with Tree-Nation.

2. Komodo

Komodo is a UK fashion brand that started in 1988. It is known as an early leader in ethical fashion. The founder, Mark Bloom, also known as Joe Komodo, created the brand after travelling in Asia, wanting to respect nature and the workers who make our clothes.

Today, Komodo uses eco-friendly materials like GOTS-certified organic cotton, hemp, bamboo, and recycled polyester. They are famous for their hand-knitted wool collections made in a solar-powered factory in Nepal.

Komodo follows a slow-fashion model, producing small batches of clothing to reduce waste. They also support “1% for the Planet,” donating a portion of their sales to help with reforestation and environmental charities.

3. Baukjen

Baukjen is a London-based brand that has recently become B Corp certified, achieving one of the highest scores in the fashion industry. They focus on stylish womenswear and are now carbon-negative across their entire supply chain. The brand uses natural, renewable fibres and has cut plastic in its packaging by more than 95%.

What makes Baukjen special is its commitment to a circular economy. They offer a “Pre-Loved” marketplace and a rental scheme, encouraging customers to share and reuse clothes rather than buy new ones for every occasion. Any unsold stock is never thrown away; it is donated to charities like Dress for Success or repurposed through their Zero Waste initiatives.

4. Thought Clothing

Thought Clothing started as Braintree Clothing in 1995. For decades, they have focused on “mindful” dressing. Their motto, “Wear me, love me, mend me, pass me on,” shows their commitment to lasting clothing. They were among the first to use sustainable materials like hemp and bamboo, which need much less water and fewer pesticides than regular cotton.

Thought Clothing is also a founding member of Common Objective, a platform for ethical fashion professionals. Their designs are made to be “seasonless,” so they don’t follow quick fashion trends that promote wasteful shopping. They work closely with small factories in China, ensuring fair pay and safe working conditions for all workers.

5. Beaumont Organic

Beaumont Organic was founded by Hannah Beaumont-Laurencia in 2008 and supports the “Slow Fashion” movement. Based in Manchester, the brand creates clean, simple designs that stand the test of time. After her experience in the high-street fashion industry, Hannah started the brand to demonstrate that clothes can be beautiful without harming workers or the environment.

The brand is known for its strong community involvement. In 2008, Hannah founded The Beaumont Organic Foundation, which donates 1% of its annual profits to support healthcare and education in Fiji. They have funded hospital improvements and provided school supplies on the island of Taveuni.

Beaumont Organic also produces its clothing in Europe, especially in Portugal, using trusted family-run factories to ensure transparency.

6. Mother of Pearl

Under the guidance of activist Amy Powney, Mother of Pearl has become a leader in sustainable luxury fashion. After winning the BFC/Vogue Designer Fashion Fund, Amy Powney launched the “No Frills” collection, the first fully sustainable collection from start to finish. This project was featured in the documentary Fashion Reimagined.

Mother of Pearl emphasises transparency by mapping every step of their supply chain. They use natural materials like organic wool and Tencel and avoid harmful chemicals in their dyeing processes.

By combining high-fashion styles with a farm-to-wardrobe approach, they illustrate that sustainable fashion can succeed at London Fashion Week.

7. KOHR

KOHR is a fashion brand based in Manchester that is changing how clothes are made in the UK. Founded in 2020 by Amy Joanne Kohl, the brand makes all its designs in-house. This helps them control quality, wages, and waste. They produce garments only when someone orders them, reducing the problem of unsold items.

KOHR is dedicated to transparency and even shares the exact hourly wages of its clothing makers. Their collections include gender-neutral basics made from organic, biodegradable, and leftover fabrics.

Impressively, 90% of KOHR’s materials are undyed, which saves thousands of litres of water and prevents harmful chemicals from polluting water during production.

8. Elvis & Kresse

Elvis & Kresse is a unique brand known for its “landfill to luxury” approach. Since 2005, they have rescued old fire hoses from the London Fire Brigade and turned them into durable, water-resistant accessories. These hoses are made from high-grade rubber that takes centuries to break down, but Elvis & Kresse transform them into stylish bags and belts.

The brand has a five-year partnership with Burberry to repurpose over 120 tonnes of leather offcuts that would otherwise be wasted. Elvis & Kresse is a certified Social Enterprise and donates 50% of its profits to charity. Specifically, all proceeds from their fire hose collection go to The Fire Fighters Charity, creating a positive impact on both society and the environment.

9. WAWWA

WAWWA is a streetwear brand based in Manchester that focuses on putting “People and Planet before Profit.” They have built their own factory in Manchester, where they train local workers and pay them more than the national living wage. This setup makes their supply chain entirely transparent.

WAWWA uses GOTS-certified organic cotton and recycled polyester to make functional, durable clothing, including hoodies, beanies, and jackets. Their “1+1” collection stands out because for every hat or pair of socks sold from this line, WAWWA donates the same item to someone homeless.

The brand blends Manchester’s textile history with a modern, vegan-friendly approach to social responsibility.

10. Yes Friends

Yes Friends, based in Bristol, wants to make ethical fashion available to everyone. Sam Mabley started the brand to show that sustainable clothes don’t have to cost a lot. By selling directly to customers and buying in large amounts, they offer organic, Fairtrade t-shirts for under £10 while still giving workers a bonus on top of their living wage.

Yes Friends works from a solar-powered building and uses partner factories in India that get over 50% of their energy from renewable sources. They have a “Great” rating from the independent directory Good On You, showing they lead in affordable ethics.

They are transparent about their production costs, demonstrating that it’s possible to create a low-cost garment while maintaining high ethical standards.

How to Spot Truly Sustainable Fashion Designers

With so much green washing in the industry, it’s essential to know what to look for when you shop. To find genuine sustainable fashion designers, look for signs of quality.

• Third-Party Certifications: Look for labels such as GOTS for organic fibres and Fairtrade for worker rights.
• Material Transparency: Green brands will clearly disclose the materials their fabrics are made of, using recycled or natural materials.
• Supply Chain Data: Visit the brand’s website to find a list of its factories and details on its ethical policies.
• End-of-Life Solutions: Check whether the brand offers repairs or a recycling program for when the clothing wears out.
