Wilko Made a Profit Almost Every Year. It Still Died.

Lesson 2: why cash, not profit, decides whether a business survives — and why owner-managed businesses walk into this one more than anyone.
Welcome back to Summer School. Last week, Lego taught us that you can grow yourself nearly to death if you never work out which products make money. This week’s lesson is closer to home, and sadder, because this one didn’t get a turnaround.
If you grew up in Britain, you knew Wilko. Paint, seeds, lightbulbs, pick ‘n’ mix — the shop that always had the thing you needed for less than you expected to pay. It started as a single hardware store in Leicester in 1930, stayed in the founding family for its entire life, and grew into 400 stores and around £1.2 billion a year in sales.
In August 2023 it collapsed into administration. By the end of October, every single store was gone. Roughly 12,000 people lost their jobs.
And here is the detail that makes it a Summer School lesson rather than just a sad story: Wilko was, for most of its life, a profitable business. It didn’t die of losses. It died of cash.
How a £1.2 billion business runs out of money
Retail runs on a simple, brutal piece of working capital mechanics. You buy the stock before you sell it. The gap is bridged by supplier credit — your suppliers effectively lend you the stock for 30, 60, 90 days, backed by credit insurers who guarantee they’ll get paid if you go under.
Which means a retailer’s real overdraft isn’t at the bank. It’s spread invisibly across hundreds of supplier accounts. And unlike a bank loan, it can be called in overnight, by people you’ve never met.
That is exactly what happened. As Wilko’s trading weakened — squeezed by inflation, by rivals like B&M and Home Bargains in cheaper retail-park locations, by expensive high-street leases it couldn’t escape — the credit insurers looked at the numbers and quietly withdrew cover. Suppliers, no longer insured, started demanding payment up front. A business with thin margins and no cash reserves suddenly had to fund its own shelves. It couldn’t. Stock gaps appeared, sales fell further, confidence fell with them, and the spiral did what spirals do. When the company finally sought emergency funding, nobody said yes. It owed around £625 million when the administrators arrived.
None of this happened overnight. Every stage of that sequence was visible months in advance — to anyone tracking the right numbers.
The decisions that emptied the tank
A business survives shocks with the buffer it built beforehand. This is where Wilko’s story turns from bad luck into a lesson, because the buffer had been steadily handed out.
In the decade before the collapse, around £77 million was paid to shareholders in dividends. Administrators later reported that £9 million of it went out after 2019 — the very years underlying profits were halving and sales were sliding. Dividends were still being paid within a year of the end, while the company pension scheme carried a deficit that ultimately left around 2,000 members facing a shortfall the regulator went on to scrutinise.
I want to be careful here, because it’s easy to write this as a morality tale, and that’s not the lesson. Family shareholders taking dividends from a family business is normal and legitimate — it’s the point of owning one. The lesson is about the question that was seemingly never asked forcefully enough: not “did we make a profit this year?” but “can the balance sheet afford to lose this cash?”
Those are different questions. Profit is an opinion — shaped by accounting policies, timing, and judgement. Cash is a fact. Wilko’s dividends were being paid out of the opinion while the fact deteriorated.
Why owner-managed businesses walk into this
Wilko was family-owned for 93 years, and I’d argue that’s not incidental to how it ended. In an owner-managed business, the person deciding the dividend and the person receiving it are the same person, or sit at the same dinner table. There is no independent voice in the room whose job is to say: not this year. The business can’t spare it.
I see the small-scale version of this constantly, and it has nothing to do with greed. A founder has had three good years. Drawings have crept up to match. The household has quietly reshaped itself around the business’s best year, not its average one. Then a soft six months arrives — a big client wobbles, costs jump — and the money that would have absorbed it has already gone. Not wasted. Just gone.
The problem is that you can’t have this conversation with yourself. Nobody can. It’s the single strongest argument I know for having someone financially senior in the business who doesn’t depend on you for their career and doesn’t come to Sunday lunch.
What to actually do — this quarter, not someday
Three disciplines, all stolen directly from how Wilko died.
First, run a rolling 13-week cashflow forecast, and treat it — not the P&L — as the document that tells you whether you’re OK. Profit tells you how the year went. The 13-week cash view tells you whether you’ll still be here to care.
Second, count supplier credit as borrowing, because it is. Add up what you owe suppliers right now and ask what happens if the terms halved. If the answer is “we’d be in serious trouble within a month,” you don’t have a cash buffer — you have someone else’s, on loan, revocable without notice. Watch for the early signals too: a supplier tightening your terms is often the first outside party to tell you the truth about your business.
Third, make dividends and drawings a balance-sheet decision. Set a cash floor the business never goes below — three months of fixed costs is a reasonable starting point at the size most of my readers run — and pay out only from what sits above it. Some years that number should be zero, and someone in the room needs to be able to say so out loud.
A 93-year-old business with £1.2 billion in sales couldn’t survive about six weeks of a cash squeeze. Whatever size you are, your survival window is a number. It can be calculated this week. Most founders have never seen theirs written down.
