It was the side-hustle that defined lockdown Britain. The cake shed. A suburban phenomenon. Garden gates propped open. A trestle table groaning under Victoria sponges. Cash on the honour system. Some bakers pulling in £1,000 a week. But the dream, as ever, is crumbling.
Behind the bunting, a political fault line. The cake shed economy is a tax evasion scandal waiting to happen. HMRC are watching. The Treasury is briefing. Sources say the Chancellor is “seriously concerned” about the scale of undeclared income. One Whitehall insider told me: “It’s not about the jam. It’s about the £100m in lost revenue.”
The National Federation of Cake Shed Proprietors (yes, it exists) is in a panic. They’ve hired a lobbying firm. Former special advisers are circling. The word “cakism” is being whispered in the tearooms of Westminster. A backbench rebellion is brewing. Tory MPs in marginal seats are terrified. Their constituents are bakers. Their constituency associations are funded by cake sales.
Labour sees an opportunity. Shadow Chancellor Rachel Reeves has been spotted at a farmers’ market in Peckham. She was “buying a brownie,” aides claim. But my sources say she was meeting with aggrieved bakers. The line being tested: “The Tories want to tax your traybakes.”
Meanwhile, the Department for Environment, Food and Rural Affairs is in a turf war with HM Treasury. Defra insists cake sheds fall under “local food production.” They want a regulatory light touch. The Treasury wants a crackdown. The Prime Minister is said to be “in the middle,” mentally noting which constituencies have the highest density of cake sheds.
Let’s look at the numbers. A survey by the Cake Shed Owners Association (CSOA) found that the average baker is earning £1,042 a week. That is above the national median wage. But here’s the rub: 87% are not registered as self-employed. They are operating outside the system. HMRC estimates that this tax gap is £500m annually. A Treasury source told me: “We can’t afford to let this slide. Not when the NHS needs funding.”
But bakers are fighting back. They argue that cake sheds are about community, not commerce. That the spirit of the enterprise is mutual aid. That taxing them would destroy the very fabric of neighbourhood life. It’s a message that has resonance. The Conservative Party’s internal polling shows that 68% of swing voters believe cake sheds are a “good thing”. Only 12% think they should be regulated.
The government is in a bind. If they crack down, they risk alienating a key demographic: Middle England. If they don’t, they lose revenue and credibility. The Chancellor is reportedly weighing a “cake amnesty”. A one-off scheme to allow bakers to declare past income without penalty. But the Treasury is split. Hardliners want a full investigation.
Expect this to become a defining issue of the next parliament. The cake shed is no longer just a place for sponge cake. It is a battleground for the soul of low-tax Britain. I’ll be watching the bunting. And the budget red boxes.
