Over the past decade, the proportion of UK flatmates aged 45 and above has risen from 10% to 16%, while the share of under-25s has fallen from 32% to 26%. That shift might sound modest, but it represents a fundamental change in who is sharing a home in Britain today. For anyone trying to make sense of the housing market — whether you’re a renter, a landlord, or just watching from the sidelines — this tells you something important: the old assumption that flat-sharing is a young person’s game no longer holds.
I’ve been watching the UK housing market for years, and this is one of those quiet trends that sneaks up on you. It doesn’t make the same headlines as house price crashes or stamp duty changes, but it affects how millions of people actually live. The rise of co-living — purpose-built shared housing with private bedrooms and communal spaces — is part of the same story. So is the growth of multigenerational house shares, where the age gap between the oldest and youngest flatmate is twenty years or more. These aren’t niche arrangements anymore. They’re becoming a mainstream response to a market that simply doesn’t work the way it used to. Here’s what you actually need to know.
What Co-Living Actually Means in Practice
The term gets thrown around a lot, so let me be clear about what we’re talking about. Co-living isn’t the same as a traditional house share where three friends split a Victorian terrace. Purpose-built co-living schemes are professionally managed buildings with private studio-style bedrooms and shared kitchens, lounges, and sometimes gyms or co-working spaces. Residents sign individual tenancy agreements, so you’re not on the hook if a flatmate moves out. The typical resident is between 26 and 40, and they value flexibility, social connection, and convenience over square footage.
What I find striking is how quickly this has moved from a niche London phenomenon to a genuinely national trend. London still accounts for 74% of completed co-living units, but regional cities like Manchester, Liverpool, and Birmingham are seeing rapid growth. In 2024, co-living completions outside London rose by a remarkable 1,508% year-on-year. That’s not a blip — that’s a structural shift. If you’re thinking about where the UK housing market is heading, this is one of the clearest signals available. For a deeper look at how urban living is evolving, I’d recommend reading our piece on the future of UK city living.
Why This Shift Matters for Everyone
This isn’t just a lifestyle preference — it’s a response to a housing market that has become genuinely unaffordable for large swathes of the population. The Nationwide first-time buyer house price to earnings ratio sits at 4.7, meaning the average home costs nearly five times the average salary. Meanwhile, average rents outside London have climbed 40.9% between Q4 2020 and Q4 2025. When both buying and renting are this expensive, people adapt. One way they adapt is by sharing homes with people who aren’t their university friends.
Consider this scenario: a single person in their late forties, divorced, no property, working in a regional city. Twenty years ago, they might have rented a one-bedroom flat on their own. Today, with rents having risen so sharply, that same flat might take up half their take-home pay. A co-living unit or a house share with older flatmates becomes not just a reasonable choice, but the only financially viable one. Housing charities have warned that homelessness among over-60s is rising, and single older people who don’t own a property are increasingly likely to end up in shared housing as they approach retirement.
What I notice when I talk to people about this is that the stigma around older flat-sharing has faded faster than most commentators realise. Matt Hutchinson, the director of SpareRoom, put it plainly: “People think of flat sharing being a young people’s game but the older cohort are growing by far the fastest.” That’s not a prediction — it’s already happening. If you’re a landlord or investor, this demographic shift has direct implications for what kind of properties will be in demand over the next decade. The viability of the buy-to-let market increasingly depends on understanding these changes.
Where People Misunderstand the Trend
The most common mistake I see is assuming co-living is just for young professionals in London. That was true five years ago. It isn’t true now. The data shows a much more complex picture, and getting it wrong means missing both opportunities and risks.
Assuming Co-Living Is a Temporary Phase
Many people still treat co-living and older house sharing as a stopgap — something people do for a year or two before “getting back on track” to owning a home. The numbers tell a different story. The proportion of flatmates aged 65 and above has tripled in the past decade. These aren’t people waiting for their mortgage application to go through. They’re retirees, divorcees, and older workers who have accepted that traditional housing pathways no longer apply to them. Nick Henley, co-founder of Cohabitas, a house-sharing site for over-40s, said 18% of the last 5,000 people who registered said they would be open to living in an intergenerational home. That’s a significant minority willing to cross age boundaries that would have seemed unusual a generation ago.
Overlooking the Regulatory Landscape
Co-living operators and landlords who ignore the regulatory side do so at their peril. The Renters’ Rights Act 2025 introduced new requirements around tenancy agreements, eviction procedures, and property standards. These rules apply to co-living schemes just as they do to traditional rentals. If you’re running a shared property without understanding the legal framework, you’re exposed. A tenant landlord lawyer can help clarify your obligations, but the key point is this: the regulatory environment is tightening, not loosening. Co-living isn’t a regulatory grey area anymore — it’s a recognised housing category with its own compliance requirements.
Underestimating the Investment Scale
Some people still think of co-living as a handful of converted office blocks in Zone 2. The reality is that UK investment in Build to Rent reached a record £5.3 billion in 2025, and single-family homes now represent 59% of that total. Co-living is a smaller slice, but it’s growing fast. Nearly £1 billion has been spent on co-living developments since 2020, and 45% of institutional investors plan to invest in this asset class by 2028. The current pipeline includes over 13,000 units either under construction or with planning permission. That’s enough to nearly triple the existing supply. This isn’t a cottage industry anymore — it’s an institutional asset class.

| Total operational UK units | 7,540 | — |
| London’s share of completed units | 74% | Declining as regions grow |
| Pipeline (under construction or approved) | 13,000+ | Could nearly triple supply |
Ignoring the Quality and Satisfaction Data
There’s a persistent assumption that co-living means cramped, impersonal, low-quality housing. The evidence suggests otherwise. A Homeviews survey found that 92% of co-living residents would recommend their landlord to friends and family. Some projects have achieved full occupancy within months of completion. That level of satisfaction doesn’t happen by accident. It reflects a product that genuinely meets a need — flexibility, social connection, and a professionally managed environment. If you’re dismissing co-living as substandard housing, you’re missing what residents actually value.

Whether you’re a potential resident, a landlord, or an investor, the rise of co-living creates both opportunities and pitfalls. Here’s how to approach it practically.
If You’re Looking for a Co-Living Space
Start by understanding what you’re actually paying for. Co-living rents typically include utilities, Wi-Fi, and cleaning of communal areas. That all-inclusive model can make the monthly figure look higher than a traditional house share, but the total cost is often comparable once you add bills. Look at the tenancy agreement carefully — individual contracts are standard, but notice periods, deposit terms, and break clauses vary. Visit the building in person if you can. The marketing photos won’t show you how thin the walls are or whether the communal kitchen actually gets cleaned. If you’re over 40 and looking for shared housing, specialist sites like Cohabitas cater specifically to your age group. A property lawyer can review your tenancy agreement if anything feels unclear.
If You’re a Landlord Considering Co-Living
The financial case is strong, but the operational demands are higher than traditional letting. Co-living requires professional management — cleaning schedules, maintenance protocols, and often on-site staff. The Renters’ Rights Act 2025 has raised standards across the board, and co-living schemes are not exempt. You’ll need to comply with fire safety regulations, HMO licensing where applicable, and minimum room size requirements. The upside is that well-managed co-living properties achieve higher yields and lower void periods than standard rentals. The downside is that the management overhead is significant. If you’re not prepared to run it like a business, it’s probably not for you.

If You’re an Investor Looking at the Sector
Institutional money is flowing into co-living, but that doesn’t mean every scheme is a good bet. The current pipeline of over 13,000 units means supply is about to increase significantly. Markets that are oversupplied with co-living could see downward pressure on rents. Focus on cities with strong employment growth, large populations of young professionals, and limited existing co-living stock. Manchester, Liverpool, and Birmingham fit that profile. London is more saturated. Also pay attention to the regulatory trajectory — the Renters’ Rights Act 2025 is unlikely to be the last piece of legislation affecting this sector. If you’re investing through a fund, check how much of the portfolio is in co-living versus traditional Build to Rent. Single-family homes now make up 59% of BTR investment, and that segment has different risk characteristics.
What the Future Holds
Nick Henley of Cohabitas put it bluntly: “I think the majority of people will have to house share in the future, that’s the way things are going. We need developers to start building shared housing, but it’s not happening. They’re building small places, single dwellings for young people.” That mismatch between what’s being built and what people actually need is the central tension in this story. The demand for co-living and shared housing is being driven by affordability, demographics, and changing social norms. The supply is growing, but it’s still concentrated in London and a handful of regional cities. If the pipeline delivers as expected, we could see the UK’s co-living stock nearly triple in the next few years. That would represent a genuine structural shift in how a significant portion of the population lives. Whether that’s a good thing depends on quality, regulation, and whether the market builds the right kind of homes in the right places.
