Short answer: for decades, charity shops made real money selling clothing they couldn't put on the rail — known in the trade as "rag" — to textile merchants for reuse or recycling overseas. That market has collapsed, and it's now costing many shops money rather than earning it, which is a big part of why some donations get turned away or feel unwelcome right now.
WRAP's own market reporting puts the numbers plainly: the price paid for charity shop textiles fell by around 41% between 2013 and 2023, and by more for textile bank donations. The Textile Recycling Association has described an unprecedented collapse in the global market, driven by a flood of low-quality fast fashion that overseas buyers no longer want, alongside rising processing and export costs. Some merchants have gone from paying charities for rag to warning they may start charging for collection instead. The Charity Retail Association has noted that rag now makes up under 2% of the average shop's income, down from a meaningful revenue stream not so long ago.
Every charity shop still has to sort what comes in: sellable stock goes on the rail, and everything else used to go out the back door to a rag merchant, clearing space for the next donation. When that merchant won't collect, or collects less often, or pays nothing, backrooms fill up fast — and a full backroom is a genuine health and safety problem, not just an inconvenience. That's the practical reason a shop might ask you to hold onto something a little longer, or turn away a bag it would have taken without a second thought a few years ago. It's also one of several pressures behind the closures happening across the sector right now, even as more people than ever want what these shops sell.
Rather than shredding old textiles down into low-value insulation or wiping rags, "fibre-to-fibre" recycling breaks clothing down and respins it into fibre that can be woven into new fabric — genuinely closing the loop instead of just delaying landfill. WRAP's UK Textiles Pact, backed by major retailers, is working to make this commercially viable at scale in the UK, and projects like ACT UK have already piloted turning 100% post-consumer textile waste into new yarn and garments.
There are smaller-scale versions of this happening locally too — East London's own FibreLab mechanically shreds textile waste and respins it into recycled fibre for filling materials and new products, run as a hyper-local, low-emissions operation rather than a shipped-overseas one. Nice to know it's happening right here rather than being shipped off somewhere else entirely.
I've also started buying shops' good, sellable overflow stock directly, for more than rag pays and more reliably collected, when a shop has more than it can move or store — and selling it on to people like Walthamstow's own market traders, who are dealing with a very similar squeeze.
Quality matters more than it used to. A shop that has to pay to dispose of unsellable stock benefits far more from one good-condition item than three items it can't sell. See our guide on preparing clothes that will actually raise funds, and check the directory for which shops near you currently have capacity for textiles — it's genuinely appreciated more than it might seem.
