London puts the spotlight back on Airbnb and Booking: the 90-day limit is no longer a mere administrative detail

Westminster has asked Airbnb and Booking.com to work more firmly against tourist rentals that exceed the legal limit of 90 days per year. This news brings to the forefront a key reality for owners, managers, and investors: operating a tourist property without first reviewing limits, licenses, land use, and documentation can generate increasingly visible risks. The case is especially relevant because it is not just a local issue in London. It reinforces a trend already seen in Spain and other European markets: more control over platforms, more data sharing, more traceability of listings, and less margin to operate without clear documentation. For the short-term rental sector, the message is direct: the profitability of a property cannot be analyzed solely based on occupancy, average price per night, or tourist demand. Before listing a property or purchasing a property for vacation rental, one must verify if the property can be legally operated and if the documentation withstands scrutiny.

Quick read Gatavia: this case should not be seen solely as international news. It reinforces a clear trend in tourist destinations and pressured cities: more inspections, more data sharing, more control over platforms, and less margin to operate without documentation.

What has happened

The City Council of Westminster, one of the most tourist-heavy and pressured areas in London, has asked platforms such as Airbnb and Booking.com to take action against the rise of short-term rentals that may be violating local regulations. In London, there is a particularly important rule: a residential property cannot be rented as short-term accommodation for more than 90 nights per year without specific planning permission. The problem, according to local authorities, is that part of the market may be exceeding that limit through multiple listings, different accounts, rotation between platforms, or insufficient information. The news is significant because Westminster contains thousands of short-term accommodations, and some of that supply is suspected of being non-compliant. The institutional message is increasingly clear: platforms can no longer merely function as commercial showcases; they are also required to cooperate in compliance monitoring.

Why it matters for owners in Spain

Although the case is British, the logic is very similar to what is already being seen in Spain and the European Union. Short-term rental has ceased to be an informal activity and is becoming an increasingly documented, monitored, and connected activity with public registries. For a Spanish owner, the practical takeaway is not that “London is regulating,” but that the model of control is changing in many cities. It is no longer reliant solely on physical inspections or neighborhood complaints. Increasingly, data from platforms, registration numbers, traceability of reservations, and consistency between what is listed and what is actually authorized carry more weight. This directly affects properties listed on Airbnb, Booking, Vrbo, and other channels. If the listing does not match the license, if a night limit is exceeded, if the homeowners association has restricted tourist use, or if the property does not fit zoning requirements, the risk ceases to be theoretical.

Short-term rental enters a data control phase

The European Union has already approved a specific framework to improve the collection and sharing of data on short-term rentals. The goal is for authorities to better understand how many properties are available, where they are located, who operates them, and for how long they are rented. This does not mean that Brussels will decide which properties can or cannot be rented out for tourist purposes. That decision still depends on each country, autonomous community, municipality, and, in some cases, homeowners associations. But it does mean that control will be easier, more automated, and harder to evade.

The trend is clear: advertisements must be better identified, platforms will have more collaborative obligations, and administrations will be able to cross data more quickly.

What a Property Owner Should Review Before Continuing to Advertise Their Property

The news from Westminster serves as a practical reminder for any owner or manager operating in short-term rentals. Before thinking about prices, occupancy, or profitability, it's advisable to review whether the property can be documented in the event of an inspection or platform review.

Profitability Can No Longer Be Calculated Without Regulations

For years, many analyses of tourist investment focused almost exclusively on gross income: average rate, occupancy, platform commissions, and cleaning. This approach is no longer sufficient. In 2026, a profitable tourist property is not merely one that secures bookings. It is one that can operate without a disproportionate risk of sanctions, ad removal, community conflict, or administrative closure. A property with high demand but poor regulatory standing can become a fragile investment. Conversely, a property with lower potential income but well authorized, well documented, and well managed can offer a more stable and defensible return.

Gatavia Conclusion

The pressure from Westminster on Airbnb and Booking confirms a trend that is already spreading across Europe: cities want to know which properties are being rented, for how many nights, with what authorization, and under what responsibility. For owners, managers, and investors, the conclusion is straightforward: short-term rentals are not disappearing, but they are becoming more professionalized. And those who want to operate with peace of mind will have to work with data, documents, and compliance. In tourist housing, profitability starts long before the first booking. It begins by checking if the property can be legally advertised, if the ad reflects reality, and if the file is prepared for an inspection.
