There is a new kind of kitchen table capitalism sweeping Britain. It involves a lot of butter, a lot of icing, and absolutely no tax receipts. Across the country, from suburban cul-de-sacs to rural farm lanes, a network of home bakers is churning out artisan cakes, sourdough loaves, and gluten-free brownies, turning their garden sheds and spare bedrooms into mini patisseries. Sources in the baking trade tell me that some of these micro-enterprises are pulling in upwards of £1,000 a week, cash in hand. But the dream, if it ever was one, is starting to curdle. The taxman has started knocking. And HMRC’s appetite for unpaid tax is not easily satisfied.
The phenomenon is part of a wider explosion in what economists call the “side hustle” economy. But the cake sheds are different. They are often invisible, operating beyond the reach of business rates, food hygiene inspections, and income tax. One baker, who spoke on condition of anonymity, told me: “I started selling to friends. Then friends of friends. Within six months I was doing weddings. I never declared a penny. I didn’t think I needed to. It was just baking.” That baker now faces a tax bill that could run into thousands after HMRC used social media data to trace her payments.
Documents obtained under Freedom of Information requests reveal that HMRC has a dedicated unit targeting online sellers. They monitor platforms like Facebook Marketplace, Instagram, and Nextdoor. They cross-reference with payment apps. They do this because the sums involved are no longer small change. One former HMRC investigator, who now advises small businesses, told me: “We used to look at plumbers and painters. Now we look at the cake ladies. They are moving thousands of pounds a week. It’s not pin money. It is a serious undeclared business.”
The scale is startling. Industry estimates suggest that the UK has over 50,000 home bakers operating as sole traders, with less than a quarter registered for tax. The average turnover per baker is around £30,000 a year, but the top earners are pulling in six figures. One case I uncovered involved a baker in Essex who was making £150,000 a year from a converted shed. She had no hygiene certificate, no business insurance, and no tax returns. HMRC caught her after a neighbour’s complaint led to a routine check. The bill for back taxes, penalties, and interest came to £47,000. She now works in a supermarket.
But the crackdown is not just about tax. Food safety is a major concern. The Food Standards Agency has issued warnings about the risks of home-produced food, especially for allergy sufferers. In 2023, a child suffered a severe allergic reaction after eating a cake bought from a home baker that contained undeclared nuts. The baker was fined £5,000. But many in the industry say the regulations are too lax. “I can sell a cake from my kitchen and no one checks my stove or my fridge,” one baker said. “It’s dangerous.”
So is the dream ending? For many, yes. The golden age of the cake shed, when you could whip up a Victoria sponge and turn it into rent money, is under siege. HMRC is getting more aggressive. Local councils are starting to crack down on planning violations. And the supermarkets, which lost sales during the pandemic home-baking boom, are fighting back with cheap mixes and ready-to-decorate kits. The margins are getting thinner.
But for every baker who closes their shed, another opens one. The lure of easy money, the freedom of being your own boss, and the sheer joy of creating something people love: those are not easy to stamp out. One defiant baker in Yorkshire told me: “They can come for me, but they won't find me. I've gone cash-only. No apps. No social media. Word of mouth. That is how the real cottage industry works.” She smiled. She also declined to give her name. She knows the taxman reads the papers.
