Where does Woolroom source its wool?

From British Wool, the UK’s farmer-owned wool marketing co-operative. We buy graded, tested lots at British Wool auction every two weeks and add each contributing farm to our traceability database.

British Wool, formally the British Wool Marketing Board, is a non-profit-making co-operative founded in 1950 and owned by its farmer members. It collects, grades, tests, sells and promotes fleece wool on behalf of UK sheep farmers.

By hand, at one of eight grading depots. Graders assess staple length, fineness, crimp, handle, lustre, colour, strength, uniformity and overall style, sorting fleeces into almost 120 grades across six principal wool styles: Fine, Medium, Cross, Lustre, Hill and Mountain.

Is British wool tested?

Yes. Wool is independently tested for micron, colour and dry yield against international standards before auction, giving buyers consistent technical data.

What is the Shepherd's Crook mark?

British Wool's trademark, launched in 1970, verifying British wool provenance. Licensed brands use it to signal certified British wool content.

Can British wool be traced to a specific farm?

Yes, and at the most detailed level. A bale usually contains wool from several farms, and British Wool's system retains the identity of every farm contributing to it, which is what allows Woolroom’s Wool ID® to connect your product to real farms.

The Organisation Behind Britain’s Wool

Beyond 'Made in Britain'

Most wool bedding brands know whether their wool is British. But very few can tell you which farm it came from, who graded it or what happened between the sheep and the sewing machine. Woolroom can, and the reason is British Wool.

1. Shearing and collection

Sheep are shorn once a year, usually between May and August, for their comfort and health. Farmers pack their fleeces into official British Wool sheets and deliver them into the collection network of eight grading depots across the UK.

2. Grading: where quality is decided

This is the stage that matters most to us, and the one almost nobody outside the industry sees.

Every fleece is assessed by hand and assigned a grade. British Wool grades into almost 120 different fleece grades, with further grades for lamb’s wool, organic wool and traceable wool.

3. Independent testing

Before wool is sold, it’s independently tested for micron, colour and dry yield against international standards.

This is the part that separates British wool from most natural-fibre supply chains. It means we aren’t buying on description or reputation. We’re buying against measured technical data. We can specify wool not just by where it came from, but by what it actually is.

For a product that has to insulate, breathe, wick moisture and stay resilient for years, that distinction is everything.

4. To the auction house

Graded, tested lots are sold through a programme of auctions running throughout the year, connecting British farms to the global textile trade—flooring, furnishings, apparel and bedding.

British Wool deliberately feeds the annual clip onto the market progressively instead of releasing a full year's production at once. That controlled approach helps maximise value for members and manages exposure to global price volatility.

Woolroom’s wool is bought at auction every two weeks. Each purchase brings a new set of graded lots into our supply chain, and every farm that contributed to those lots is added to our traceability database. That rhythm keeps our wool current rather than sitting in long-term storage, and it means the list of farms behind our products keeps growing.

Three Levels of Traceability

More and more, knowing a material is “British” is just the starting point. British Wool’s system offers provenance at three places:

British farm provenance

All of the wool British Wool handles comes from British farms. It doesn’t grade or sell wool from anywhere else. That’s the foundation, the assurance that the fibre is genuinely British, not sourced internationally and simply marketed as British.
Regional traceability

Because wool passes through one of eight regional grading depots, it can be traced to the part of the country it came from—Scottish borders, Welsh hills, West Country.
Farm-level traceability

This is the most detailed level. Individual bales can be traced back to the farms that contributed wool to them, creating a direct line between a finished product and the people who produced the fibre.

How a Bale is Actually Traced

The system is built into the physical movement of the wool.

Delivery. A farmer’s consignment receives a unique document number, recorded on their Receipt of Wool.
Grading. Wool is sorted into skeps, each carrying a unique data card that keeps it connected to the right farmer.
Weighing. Data is captured against the farmer’s account.
Baling. As wool from different farms is combined by grade, the tracking information travels with it. Each finished bale receives its own identification code.

Underpinning all of it is British Wool's investment in a QR-code-based traceability system, so origin information survives grading, baling and auction instead of evaporating the moment individual fleeces enter the commercial supply chain. It’s an old agricultural system with a modern digital record running alongside it.

We’ll clarify something that’s often glossed over: a bale weighs roughly 350–400kg and usually contains wool from several farms. Traceability doesn’t mean one bale equals one farm. It means the identities of the farms contributing to that bale are retained, not lost when the wool is pooled by grade.

That's what powers Wool ID®. Every Woolroom product carries a lot number on its care label and a QR code. Scan it and you can read about the farms, the farmers and the flocks behind your wool: Cracrop Farm in Cumbria, Boundary Farm in Rutland, Manor Farm in Dorset, Llanfechan in Wales, and a growing list of others.

Traceability Pays the Farmer

This isn’t only a consumer benefit. Traceable wool commands a premium above standard auction prices, and that additional value is returned to British Wool’s farmer members.

It creates a genuine link between what shoppers want to know and the people producing the fibre. You want to know where the wool in your duvet came from. We want to demonstrate responsible sourcing. And the farmer who grew that fleece is paid more because the market specifically asked for it.

Provenance becomes economic value, not just a story.

The Shepherd’s Crook Mark: Your Verification

British Wool trademarked the Shepherd's Crook mark in 1970, and it’s since become the established symbol of British wool provenance.

It matters because “wool” on a label tells you almost nothing. Wool can be imported from anywhere, blended with anything, and still be accurately described as wool. The Shepherd’s Crook is a licensed mark that verifies the wool in a product is genuinely British—sourced through British Wool, from British farms.

For you, it’s a simple starting point when comparing products. Here at Woolroom, it means our claims are verifiable beyond our own say-so. Woolroom holds the Authentic Traceable British Wool certification alongside Authentic Traceable Organic British Wool for our organic washable collection(among othercertifications).

Wool: Britain’s Oldest Industry

Wool is widely regarded as Britain’s oldest industry, and it’s not an exaggeration to credit the fibre with building this country to some degree. Wool’s production, processing and trading may well be the first commercial industrial enterprise in the nation’s history, serving as the backbone of the medieval economy. Kings taxed its export, and Norwich, York and Coventry made their wealth on it.

The Woolsack is where the Lord Speaker in the House of Lords sits and resembles a large square cushion covered in red cloth. In 1938 it was re-stuffed with a blend of wool from Britain and the other wool producing nations of the Commonwealth. The woolsack is thought to have been introduced in the 14th century to reflect the economic importance of the wool trade in England.

More than a Wool Merchant

British Wool's role extends past collecting and selling fibre. It runs approved shearing and wool-handling training to keep those rural skills alive for the next generation — because the industry depends on far more than sheep and farms. It depends on generations of practical knowledge in shearing, handling, sorting and presenting wool correctly.

It also works to create demand, partnering with manufacturers, retailers and designers, and supporting initiatives such as the Campaign for Wool. Producing wool is only sustainable for farmers if there's a market for it.

Between the sheep and the finished product, British Wool provides the collection infrastructure, the grading expertise, the independent testing, the auction route to market, the promotion that creates demand, the training that preserves the skills, and the traceability that lets us tell you the truth about where your wool came from.

What It Means for Your Bedding

This is what's behind every Woolroom duvet, pillow, and mattress: a fleece from a named British farm, graded by hand, tested against international standards, and tracked every step of the way. It's not a claim about wool. It's a record of it.

Better performance means grading and micron testing ensure the wool in your duvet was selected for bedding, not simply available. Verified provenance means the Shepherd's Crook and Wool ID® are checkable, not adjectives. It's a fairer deal for farmers, since traceable wool earns a premium that goes back to the farm. And it's a supply chain you can see, documented from shearing to sale.
