Over the past year, nearly 94 million guest nights were spent in short-term lets across the UK, a jump of more than 10% compared with the year before. That figure, from the latest ONS data, tells you one thing clearly: this isn’t a niche trend anymore. It’s a structural shift in how people travel, and it’s reshaping the places where we live.
I’ve been writing about UK property and housing policy for long enough to see patterns repeat. But the short-term letting story is different. It cuts across housing supply, local economies, tourism, and tax policy all at once. The questions I hear most often aren’t about whether Airbnb is good or bad. They’re about what it actually means for a community when a growing share of homes stop being homes and start being hotels. Here’s what you actually need to know.
If you’re a homeowner wondering whether to let your property on a short-term basis, or a resident watching your street change, the data helps cut through the noise. A buy-to-let strategy under pressure might look more attractive as a short-term let, but the rules are tightening fast. A smart leak detector like the X-Sense Wi-Fi Water Leak Detector is a sensible precaution if you’re letting a property remotely — one burst pipe can wipe out a month’s income.
How Short-Term Letting Actually Works in the UK
The first thing to understand is that short-term letting isn’t one thing. It covers everything from a spare room let for a weekend to a dedicated holiday cottage let for 40 weeks a year. The rules, the tax treatment, and the community impact are different for each.
What I notice most is how quickly the landscape has shifted. In 2022, there were around 257,000 short-term letting listings in England alone. By 2024, the UK was seeing over 90 million guest nights a year. That kind of growth doesn’t happen without consequences. The regions bearing the brunt are the South West, London, and the South East, which together account for 62% of English listings. If you live in Cornwall or Westminster, you’re not imagining the change — the numbers back it up.
If you’re thinking about letting your property, the first question isn’t “how much can I earn?” It’s “what am I allowed to do?” In London, entire homes can’t be let for more than 90 nights a year without planning permission. Scotland now has a mandatory licensing scheme, with over 27,000 licences in operation by the end of 2024. Wales is moving in the same direction. The rules are becoming a patchwork, and managing a rental property effectively now means staying on top of local regulations as much as guest bookings.
What the Growth Means for Local Communities
The most visible impact of short-term letting is on housing supply. When a property moves from the long-term rental market to short-term lets, it’s effectively removed from the pool of homes available for local residents. In areas with high tourist demand, that can push rents up and reduce availability for people who actually live and work there.
Cornwall is a stark example. It had the second-highest number of guest nights of any UK local authority in the latest period — over 3.5 million. The seasonal variation is extreme: August 2024 saw 803,920 guest nights, ten times the January 2025 figure of 78,700. That kind of swing creates a housing market where properties earn more from tourists for three months than from tenants for twelve. The council has responded by applying a 100% council tax premium on second homes, but the underlying tension remains.
Westminster tells a different story. It topped the list with over 4.1 million guest nights, a 16.7% increase on the previous year. Here the issue is less about seasonal emptiness and more about the sheer density of short-term lets in a central urban area. London’s 90-day rule was supposed to limit this, but enforcement has been described by London Councils as “a near-impossible task” without a registration scheme. Only 91 complaints were made in Kensington and Chelsea over two years, despite an estimated 9,584 short-term lets in the borough.
My take is this: the economic benefit is real. Airbnb travel added £5.7 billion to UK gross value added in 2023 and supported over 75,000 jobs. But those benefits are concentrated in tourist hotspots, while the costs — higher rents, fewer long-term rentals, neighbourhood disruption — are borne by local residents. If you’re a host, you’re part of that equation whether you think about it or not. A video doorbell can help you manage guest arrivals remotely, but it won’t solve the tension between your income and your neighbour’s housing costs.
Where Hosts and Regulators Are Getting It Wrong
The short-term letting boom has created a set of recurring problems. Some are mistakes by hosts who don’t understand the rules. Others are failures of regulation that leave communities exposed. Here are the most common ones I see.
Ignoring the 90-day rule in London
The rule has been law since 2015, but compliance is low and enforcement is weaker. If you let an entire home in London for more than 90 nights in a calendar year without planning permission, you’re breaking the law. The risk of being caught is currently low, but that’s changing. A registration scheme for short-term lets has been proposed, and if it comes in, historical breaches could become visible. My advice: don’t assume you’ll get away with it. The cost of a planning enforcement notice can far exceed the extra income.
Assuming the Rent-a-Room scheme covers everything
The scheme lets you earn up to £7,500 a year tax-free from letting a furnished room in your main home. But it only applies if you’re a resident landlord letting a room in the property where you live. If you’re letting a separate property, or if you’re not living there yourself, the £1,000 property allowance is the relevant threshold — and it’s much less generous. A typical host earning £6,200 a year might assume they’re covered, but the wrong allowance could mean an unexpected tax bill.
Overlooking the end of Furnished Holiday Lettings tax reliefs
The FHL regime was abolished from April 2025. Hosts who previously claimed full finance-cost relief, capital allowances, and capital gains tax reliefs have lost those advantages. The Exchequer expects to recover £210 million a year by 2028-29 from this change alone. If you’re a host who relied on those reliefs, your net income just dropped. You need to recalculate your position and consider whether short-term letting still makes financial sense compared with a standard tenancy.
Underestimating seasonal volatility
Cornwall’s August guest nights were ten times its January figure. That kind of seasonality means cash flow is unpredictable, and properties sit empty for months. Hosts who budget based on peak-season income can find themselves struggling in the off-season. A realistic financial plan accounts for the quiet months, not just the busy ones.

The rules have changed, and they’re going to keep changing. Here’s what I’d do if I were starting out or reviewing an existing let.
Check your local registration and licensing requirements
Scotland’s mandatory licensing scheme had over 27,000 licences in operation by the end of 2024. Wales is introducing its own registration system. London has the 90-day rule. Some councils are introducing additional restrictions. Don’t assume national rules are the only ones that apply. Check your local authority’s website for specific requirements. If you’re in Scotland, you need a licence before you can advertise. If you’re in London, you need to track your letting nights and stop at 90 if you don’t have planning permission.
Understand your tax position now the FHL regime has ended
The abolition of Furnished Holiday Lettings tax reliefs from April 2025 is a major change. You can no longer claim full finance-cost relief on mortgage interest — you’re limited to the basic rate of tax relief, just like a standard landlord. Capital gains tax reliefs are gone too. If you were relying on those to make the numbers work, you need to recalculate. The £210 million the government expects to recover by 2028-29 is coming out of hosts’ pockets. A financial advisor can help you model the impact on your specific situation.
Keep proper records for HMRC reporting
Since January 2024, platforms like Airbnb, Vrbo, and Booking.com have been required to report UK host earnings to HMRC. The first reports were filed in January 2025 covering 2024 income. HMRC has already issued nudge letters to hosts covering earlier tax years. This isn’t a future possibility — it’s happening now. Keep a record of every booking, every expense, and every night the property was occupied. If HMRC asks questions, you need to be able to answer them.
Prepare for seasonal cash flow gaps
If your property is in a seasonal area like Cornwall or the Highlands, your income will be heavily weighted toward summer months. January had the fewest guest nights across the UK — just 4.2 million compared with August’s 12.8 million. Build a cash reserve to cover the quiet months, and consider whether a mix of short-term and medium-term lets could smooth out the income. A generational shift toward renting means there’s demand for longer lets too, and the tax treatment is often simpler.

Short-term letting isn’t going away. The demand is too strong, and the economic contribution — £5.7 billion to UK GVA in 2023 — is too significant for governments to ban it outright. But the era of light-touch regulation is ending. Licensing schemes, tax changes, and better enforcement are all coming. The hosts who thrive will be the ones who take the rules seriously, plan for the quiet months, and understand that their income has consequences for the people around them.
