The Singles Tax: How Friends Are Pooling Resources to Beat Higher Living Costs

Leanne was in her late twenties when her relationship ended, and she faced a problem that millions of single people in Britain know well: the things that couples take for granted—splitting rent, dividing utility bills, sharing a mortgage—suddenly became unaffordable on one income alone. She had a decent salary and wanted to buy a home with a garden and parking space in Kent, where she'd grown up. But the market prices made it impossible to go it alone.

Her friend Sarah, whom she'd known since school, was in a similar bind. Sarah worked as cabin crew and was renting a room in a shared house in Brighton, wanting to move back to Kent but unable to afford the deposit and monthly payments on her own. When Sarah suggested they buy a property together, Leanne's first instinct was to refuse. It seemed too complicated, too risky. But after consulting a mortgage adviser, they decided to try it—and what followed became a small case study in how to beat what's increasingly being called the singles tax.

The singles tax is real, though hard to pin down precisely. Estimates suggest single people pay anywhere from hundreds of pounds to £10,000 extra per year compared to couples, depending on where they live. The math is straightforward: rent or mortgage payments can't be halved between one person and nobody. Council tax is 25 percent cheaper for a single occupant than for a couple, but that's not the same as paying half. Subscriptions, utilities, internet—all of these are fixed costs that couples split but singles bear alone. Then there are the discounts designed for pairs: two-for-one cinema tickets, railcards for couples, gym memberships that reward partnership. Solo travelers often pay a premium called the single supplement. For a country where 36.8 percent of adults have never married or entered a civil partnership, and where 8.6 million people live alone—nearly a third of all households—this adds up to a significant financial penalty for being unattached.

Leanne and Sarah approached their purchase methodically. They agreed in advance that they'd live together for at least two years, later extending that to four, and they discussed what would happen if one of them wanted to leave. They split the mortgage payments proportionally, accounting for their different salaries. They drew up a declaration of trust to protect themselves when it came time to sell. They opened a joint account for household bills, with Sarah taking on the role of tracking what each person owed each month. Because they had similar eating habits, they also shared meals and took turns cooking, which cut their food costs. Leanne called it their happy home, not their forever home—a phrase that captured the pragmatism of the arrangement.

After four years, they sold the house for a profit. The equity they'd built went toward separate purchases for each of them. Sarah says neither of them would have been able to do what they did without that shared property. Leanne agrees, though she thinks she might eventually have afforded her dream home on her own—it just would have taken much longer. "The hidden singles tax," she says, "is that everything has to take so much longer for you to be able to be in a position of affordability to do what you want to do."

Their success caught the attention of their friend Philly, who saw an opportunity. She launched Cucoon, an online platform designed to match single people who want to buy property together. The aim, she says, is to level the playing field—particularly in housing, where the singles tax bites hardest.

Other solutions are emerging too. Julia Pearson started Just4One about nine years ago after discovering that solo holidays came with a financial penalty. The website now lists travel providers that don't charge single supplements and offers practical advice for managing life alone. She's tried adding a named driver to her car insurance and saved 8 percent on her premium, though she notes the RAC warns this doesn't always work. She also borrows tools from friends for home renovations and shares plant cuttings from her garden. "Rather than thinking, 'I've got to go out and buy that,' think about how else can you play that, what else can you do aside from having to buy something?" she says. "It's good for the social side as well, two benefits in one."

The solutions range from the formal—co-buying with legal protections—to the everyday: shared dinners where hosts take turns cooking with bulk ingredients, borrowing circles where expensive items like lawnmowers circulate among friends, errand pooling where people share fuel costs by taking turns driving to the supermarket. None of these are new ideas. What's new is the recognition that single people, now more than a third of the adult population, need them more than ever.
