Want to know the best ethical and sustainable knitwear brands in the UK, to go to for cosy jumpers, sweaters and cardigans? I’ve got you covered with this handy guide to the brands for men and women to know, as well as the ethical issues to be aware of.

Knitwear is a key winter staple, beloved by many for its natural thermoregulatory abilities to keep you warm without feeling sweaty. But beyond the cosy factor, many knitted items come with a footprint of animal cruelty, toxic dyes, and less-than-natural materials.

Wool may be a natural and renewable material, but many brands weave synthetic fibres, such as acrylic through their wool knitwear.

There are numerous reasons for this. The use of acrylic is said to reduce bobbling and help your item retain its shape. However, the main reason is that acrylic is cheaper than using natural wool. This means many brands lean towards these cheaper synthetic fibres. Yet acrylic is plastic, so this means your knitwear is derived from fossil fuels and will shed potentially harmful microplastics every time it’s washed.

However, it’s not a simple case of 100% pure knitwear being good and synthetic fibres being bad. Within the woollen industry, there are key issues of animal cruelty within the supply chain.

Mulesing, for example, is a practice carried out on merino lambs to help avoid flystrike – an infection caused by flies. Here, strips of skin are removed from the lambs in a painful procedure without anaesthesia. It’s a cruel practice, that some countries have banned, whilst others like Australia continue to allow mulesing.

The Eco-Friendly Knitwear Brands To Know

Thankfully, there are more sustainable and kinder ways to buy knitwear. Some brands use recycled wool, others opt to give a new life to existing garments, and other eco-friendly brands use 100% natural wool sourced from transparent and traceable farms.

To help point you in the right direction, I’ve rounded up my favourite eco-friendly woollen brands to know, that are as stylish as they are sustainable.

The price range key for this guide is:

 £ = Under £50 | ££ = £50 – 100 | £££ = £100+
