21 of the UK’s best sustainable high street brands in 2023

The high street is not the first place that springs to mind when thinking about shopping sustainably.

But while the majority of mainstream brands don’t have the best reputation when it comes to environmental and ethical responsibility, the global push for sustainable fashion is driving more and more brands to improve their policies.

What makes a high street brand sustainable?

In this day and age, with greenwashing rife, the word “sustainable” can be an empty promise made by many brands.

That’s why conscious shoppers have to develop a keen eye for what true corporate environmental and social responsibility looks like.

Eco-friendly high street brands will often have third-party certifications attesting to their sustainable sourcing practices and the use of recycled materials, as well as recycling and free repair schemes. They will also promote transparency across all stages of production, and set science-led targets to reduce carbon emissions and textile waste.

Sustainable brands should also implement ethical practices when it comes to their workers’ rights, from prohibiting child labour across all suppliers to providing a true living wage in their supply chain. Not to mention that they should have well thought out animal welfare policies.

Ethical companies will be transparent about their labour standards, auditing their overseas suppliers and showing their commitment through third-party certifications like Fairtrade and Fair Wear.

For more on certifications to look out for, see our guide in Why Is Ethical and Sustainable Fashion Important: What Everyone Should Know, and for tips on how to avoid greenwashing, see our article here.

So, what are the UK sustainable high street brands you should be on the lookout for?

Good On You rates them as “It’s a Start” too, while Remake give them a not bad 38.

12. Converse

Almost every closet comes with an iconic pair of chucks.

Converse has been working towards making its practices more sustainable by using more recycled materials and setting ambitious targets for reducing greenhouse gas emissions.

The brand’s Renew collection is the most eco-friendly yet, featuring a sole made with partly recycled rubber scraps and 100% recycled canvas.

You can also recycle your old pair of chucks by bringing them to a Nike shop, Converse’s owners.

Converse still has a way to go to ensure the payment of a living wage to its workers so Good On You rates them as “It’s a Start”.

13. H&M

Swedish fashion giant H&M might not be the first company that comes to mind when you think of UK high street sustainable brands. They are ultimately a fast fashion brand that promotes consumption. However, the brand is taking major steps towards sustainability and outshines its fast-fashion competitors in this regard.

The brand is moving to textile-to-textile recycled polyester (as opposed to recycled PET bottles) by 2025 and implement more closed-loop practices, reusing scraps from the textile industry.

In 2020, H&M also ranked among the top 5 in Fashion Revolution’s Transparency Index.

14. Adidas

Adidas is another popular brand of trainers that has recently started to embrace eco-friendly practices.

The German company is using more and more recycled and eco-friendly materials, as well as using non-toxic dyes to reduce the product’s impact on water waste and pollution.

The brand’s denim is also made by implementing water-saving practices, and synthetic indigo dye is slowly being phased out.

Like the brands before them, Good On You recognises the steps M&S are taking to be more environmentally sustainable, however they still fall down on their lack of payment of a living wage in their supply chain, so they are rated as “It’s a Start”. Remake gives them 31.

16. Seasalt

M&S is also the main stockist for Seasalt, a colourful fashion retailer inspired by the beauty of Cornwall.

Seasalt uses eco-friendly materials like organic cotton, bamboo fabric, linen, and recycled PET bottles to create part of its collection, using renewable energy for all direct operations.

The brand uses recyclable packaging and offers a take-back scheme to recycle all items.

Seasalt is doing a lot of things right, but like others, still has a way to go. Good On You rate them as “It’s a Start”.

18. Nike

Nike is not always the first choice when thinking about sustainable high street brands in the UK, but it has come a long way.

Nike has also started to use at least 50% recycled materials (like polyester and nylon) for apparel and 20% for trainers, and the brand’s Move to Zero initiative is implementing more closed-loop recycling practices.

The company also uses either organic cotton, BCI cotton, or recycled cotton for all products.

They are starting to implement a living wage in their supply chain and received a good score in the Fashion Transparency Index but need to improve their animal welfare policies. They too are rated “It’s a Start” by Good On You and get 25 from Remake.

19. G-Star RAW

Dutch denim company G-Star RAW is using more recycled cotton and BCI cotton for its jeans, so much so that only 1% of products are made with conventional cotton.

G-Star is also using Tencel, recycled elastane, hemp, and eco-friendly viscose, as well as pollution-reducing practices as part of its commitment to ZDHC.

G-Star are rated as “It’s a Start” by Good On You.

20. Uniqlo

Uniqlo is the king of practical basics, and it has started to include more sustainable and recycled materials as part of its collection.

The brand uses recycled PET bottles to create more sustainable polyester and employs BlueCycle technology to reduce the amount of water used for the jeans finishing process, by up to a whopping 99%.

They need to improve their worker welfare and payment and so are rated “It’s a Start” by Good On You and given 24 by Remake.

21. Nobody’s child

Not traditionally thought of as a high street brand but super ethical Nobody’s Child is now available in selected John Lewis stores and Selfridges.

The brand strives to be as conscious as possible in every aspect; from paying a living wage and ensuring good working conditions in its supply chain, to the use of sustainable materials such as organic cotton and Lenzing viscose.
