Over half of UK renters are now “flathugging” — staying put in their current shared home even though they want to move, according to data from flatshare site SpareRoom. That figure tells you something important about the state of the market right now: moving between shared houses has become expensive, stressful, and uncertain enough that many people are choosing to put up with what they’ve got rather than risk finding something worse. I’ve been writing about the UK rental market for years, and the one question that comes up more than any other is how to make shared accommodation actually work — not just survive it, but live in it without constant friction over money, space, or housemates. Here’s what you actually need to know.
Shared accommodation is the cheapest way to live in most UK cities, but that doesn’t mean it’s simple. The average UK room rent now sits at £747 per month, and in London it’s £985. Those figures have barely budged in the past year, but they follow a five-year period where rents rose 34% nationally and 38% in London. The result is that more people are sharing for longer, and the dynamics inside those homes are shifting. If you’re looking for a room or already living in one, the practical decisions you make about contracts, bills, deposits, and housemate agreements matter more than ever. I’ve put together a UK flat-hunting checklist that covers the basics, but this article goes deeper into the specific challenges of shared living.
What Shared Accommodation Actually Means for Your Rights
The most important thing to understand is that not all shared housing is the same in the eyes of the law. If you rent a room in a house where the landlord also lives, you’re a lodger — and your rights are much weaker than a tenant’s. A lodger can be asked to leave with “reasonable notice”, which in practice can be as little as a week. If you and your housemates all signed one tenancy agreement together, you’re joint tenants, which means you’re collectively responsible for the full rent — if one person leaves, the rest of you have to cover their share. If you each signed separate agreements for your own room, you’re individual tenants, and your liability is limited to your own room. That distinction matters enormously when things go wrong.
What I tend to notice is that most people in shared housing don’t know which category they fall into until there’s a problem. A housemate moves out without warning, and suddenly you’re on the hook for their share of the rent. Or the landlord gives you seven days to leave because they’ve decided to sell, and you have no legal grounds to stay. Before you move into any shared property, ask the landlord or letting agent directly: “Am I a lodger, a joint tenant, or an individual tenant?” Then check that the answer matches what’s in the contract. If you’re unsure about the terms, it’s worth getting a tenant and landlord lawyer to review the agreement — a small upfront cost that can save you thousands later.
Why the Rising Cost of Renting Is Changing Shared Living
The financial pressure on shared households is real and growing. Over half of flatsharers — 51% — have used a loan, credit card, advance, or second income to help pay their rent in the past year. That’s not a niche problem; it’s the majority. And the burden falls unevenly: women are more likely to be “rent burdened” than men, meaning they spend more than 30% of their gross income on housing. For someone earning the National Living Wage of £12.21 per hour in London, they’d need to work 63 hours per week to keep rent within that 30% affordability guideline. That’s nearly two full-time jobs just to afford a room.
Consider this scenario: you’re a graduate moving to Oxford for an entry-level role. The minimum starting salary you’d need to afford a room there is £32,853. If your actual salary is lower, you’re either sharing with more people, living further out, or relying on credit to bridge the gap. That’s not a budgeting problem — it’s a structural one. And it’s why flatsharers are getting older. Under-35s in the shared market are declining, while those aged 35 and over are rising. People aren’t choosing to share because they love the company; they’re doing it because renting alone or buying a home is out of reach.
What I’d do in this market is be ruthless about the total cost of a room, not just the rent. Ask about bills, council tax band, broadband, and whether the deposit is protected in a government-approved scheme. If the total monthly cost pushes you over 30% of your take-home pay, you need to either earn more, share with more people, or look in a cheaper area. A guide to the hidden costs of renting can help you calculate the real figure before you commit.
Where People Go Wrong in Shared Accommodation
Not Checking the HMO Licence Before Moving In
If a property has three or more tenants from different households and it’s not a single-family home, it legally needs a House in Multiple Occupation (HMO) licence from the local council. Many tenants don’t check this, and the consequences can be serious. An unlicensed HMO means the landlord may not be able to use a Section 21 eviction notice, and you could apply to a rent repayment order to claim back up to 12 months’ rent. But you can only do that if you know the property should be licensed. Before you sign anything, search your council’s online register of licensed HMOs. If the property isn’t on it, ask the landlord why. If they can’t give you a straight answer, that’s a red flag.
Ignoring the Deposit Protection Rules
Your deposit must be placed in a government-approved tenancy deposit scheme within 30 days of payment. If it isn’t, the landlord cannot use a Section 21 eviction notice, and you can claim compensation of between one and three times the deposit amount. This applies to assured shorthold tenancies in England and Wales. Lodgers are not covered by this protection, which is another reason to know your tenancy type. If you’re a lodger, your deposit is not legally protected — so negotiate a lower amount or get a written receipt.
Relying on Verbal Agreements for Bills and Chores
Money disputes are the most common cause of tension in shared houses. Who pays for the broadband? What happens if someone uses more electricity than everyone else? How do you split the council tax if one person is a student and exempt? Without a written agreement, these questions lead to arguments and, in some cases, one person covering costs that should be shared. A simple shared house agreement — signed by everyone — should cover: how bills are split, how the deposit is divided when someone leaves, how notice is given, and what happens if someone doesn’t pay. It doesn’t need to be a legal document; a signed email or WhatsApp message is better than nothing.
Not Planning for a Housemate Leaving
In a joint tenancy, if one person leaves without finding a replacement, the remaining tenants are legally responsible for the full rent. That can mean an extra £500–£1,000 per month per person overnight. The fix is to agree in advance how replacements will be found and approved. Include a clause in your written agreement that says: any tenant who wants to leave must give at least one month’s notice and help find a suitable replacement. The landlord must approve the new tenant, but the departing tenant should bear the cost of advertising and viewings. A guide to decoding tenancy agreements can help you spot these clauses before you sign.

| City | Average Room Rent (Q1 2026) | 5-Year Change |
|---|---|---|
| London | £985 | +37% |
| Edinburgh | £823 | +28% |
| Belfast | £650 | Steep rise |
| Cardiff | £586 | +40% (Wales) |
What I’d flag here is that the steepest rises aren’t always in the cities you’d expect. Over the past five years, the biggest increases have been in Belfast, Newcastle, and Cardiff, not just London. If you’re looking for value, don’t assume a smaller city means cheaper rents — check the local data first.

How to Find and Secure the Right Shared Property
Start Your Search With the Right Filters
Use sites like SpareRoom and RoomsForLet, but don’t just look at the rent. Filter by bills included, deposit amount, and whether the property has an HMO licence. Look for listings that mention the council tax band and broadband speed — these are signs of a professional landlord who has thought about the details. When you message a landlord or current tenant, ask three specific questions: what’s the total monthly cost including bills, how long have the current housemates lived there, and what’s the notice period for leaving. If they can’t answer clearly, move on.
View the Property With a Critical Eye
During the viewing, check the condition of shared spaces — the kitchen, bathroom, and living room. Are there enough sockets? Is the boiler serviced? Is there a working carbon monoxide alarm and smoke alarm? These are legal requirements, not optional extras. A carbon monoxide alarm costs very little and could save your life. If the landlord hasn’t installed one, that tells you something about their approach to safety. Also check the water pressure, the heating system, and whether the windows open and close properly. These are the things that will drive you mad if they don’t work.
Understand the Rent a Room Scheme if You’re the Homeowner
If you own a home and are considering renting out a room to a lodger, the Rent a Room Scheme lets you earn up to £7,500 per year tax-free. That’s £625 per month. The scheme applies whether you own or rent the property yourself, as long as it’s your main home. The lodger must live in the property with you, and you must share some living space. The scheme is separate from HMO licensing, which applies only to properties with three or more tenants from different households. If you’re thinking about taking in a lodger, check the beginner’s guide to renting for the full rules.
Prepare for the Future: What Happens When Rents Rise Again
The data shows that UK room rents have been flatlining in 2026, but that follows years of steep increases. The supply of lodger rooms is now in decline — lodger ads fell 2.5% year on year in January 2026 after four years of growth. That means fewer rooms are available, and when demand picks up again, rents will likely rise. If you’re in a shared property now, consider locking in a longer tenancy — 12 months or more — to protect yourself from rent increases. If you’re looking for a room, be prepared to act fast when you find a good one. The best properties go within days, not weeks.
