London Is Officially the Loneliest City in the World. Being Single There Also Costs £21,000 a Year.
Let's start with the ranking nobody wants to top.
Global loneliness data puts London at the very top of the list: 55% of London residents say they feel lonely, the highest rate recorded for any major city in the world. That's not a small-sample survey finding — it's consistent with earlier city data showing roughly 700,000 Londoners classified as severely lonely between 2018 and 2019, 61% of them single and living alone. In a city of nearly nine million people, more connected on paper than almost anywhere on Earth, more residents report feeling isolated than anywhere else measured.
Here's the number that makes that ranking make sense: being single in London costs, on average, an extra £21,000 a year, according to a 2024 analysis by workplace insights firm Nous. That figure includes £16,254 in annual rent for a one-bedroom flat, £1,851 in utilities, and the accumulated cost of every expense a couple would otherwise split — deposits, insurance, council tax, the whole structure of shared living that London's housing market prices as a genuine financial advantage.
Loneliest city in the world. Most expensive city to be single in. Those two facts are not a coincidence sitting next to each other.
What the money actually does to connection
A "singles tax" of £21,000 doesn't just sit quietly on a spreadsheet. It reshapes daily behaviour. Add £80-plus for a casual dinner for two in central London, £15 for a single cocktail, and £50 a head for event tickets, and the basic financial math of dating — before any relationship even forms — becomes a genuine deterrent. National research has found that one in four young UK singles now say cost-of-living pressure has made them less likely to seek out a relationship at all.
It compounds with London's other defining feature: time. Londoners work longer average hours than residents of any other UK city, and rising housing costs have pushed more people further from the centre, stretching commutes and shrinking the window for anything resembling spontaneous social life. By the time someone finishes work, travels home, and handles the basics of daily life, dating competes for what little energy is left — and loses, more often than not.
Marriage isn't just declining. It's declining on a schedule.
The longer-term trend is stark enough that a UK think tank put a number on it. Research by Civitas found that the number of marriages in the UK has nearly halved over the past 35 years — and extrapolated forward, the current trajectory would see marriage effectively disappear as an institution by 2062. That's a projection, not a certainty, and trends like this rarely continue in a straight line. But it's a striking marker of how far the decline has already travelled, and London, as the country's most expensive and least affordable major city, sits right at the front edge of it.
Surrounded, and still unseen
What emerges from the numbers isn't a city short on people. It's a city where the cost of building a life with someone has climbed so high that a huge number of Londoners are, functionally, opting out — not because they've stopped wanting connection, but because the practical path toward it keeps getting narrower. Living with flatmates well into your thirties because solo rent is unaffordable. Rationing dates because £80 dinners add up fast on top of rent that already eats half a paycheck. Working the long hours the city demands, then having nothing left for the evening plans that might have led somewhere.
That's the real shape of London's loneliness — not an absence of people, but a structural squeeze on the time, money, and energy it takes to actually meet the right one. In a city where every one of those resources is scarcer than almost anywhere else in the world, the case for a more deliberate, curated approach to meeting someone isn't a luxury. It's simply a rational response to what the city's own numbers are describing.
