Westminster's Short-Term Let Crackdown: Why Compliant Serviced Accommodation Is the Big Winner

Westminster Council has fired a warning shot that every London landlord needs to hear. Council leader Paul Swaddle recently described short-term renting in the West End as "out of control," calling for tougher enforcement of the 90-day rule and demanding that platforms like Airbnb take more responsibility for policing illegal listings. The council is actively pursuing enforcement action against properties breaching planning regulations, and the message is clear: the era of unregulated, amateur short-term letting in central London is coming to an end.

But here's what makes this story so interesting for savvy property investors. As non-compliant operators are pushed out of the market, the supply of short-term accommodation in London's highest-demand postcodes is going to shrink. And that creates a genuine premium for landlords who are running professional, fully compliant serviced accommodation operations.

Let's break down exactly what this means, how serviced accommodation works as a strategy, and what you need to do to position yourself on the right side of this shift.

What Is Serviced Accommodation and Why Does It Matter Now?

Serviced accommodation (SA) sits in the sweet spot between traditional buy-to-let and hotel hospitality. Think fully furnished apartments with hotel-quality linens, professional cleaning, and flexible booking terms. Guests might stay for a few nights or a few months. The key difference from a standard Airbnb listing is the level of professionalism, consistency, and compliance baked into every aspect of the operation.

With Westminster actively cracking down on casual operators who exceed the 90-day limit without planning permission, the landlords who will thrive are those treating SA as a proper business. That means either securing the correct planning consent for year-round short-term letting or, increasingly, pivoting towards mid-term corporate bookings that fall outside the 90-day restriction entirely.

The Corporate Travel Opportunity in Central London

Here's where things get exciting. London's corporate travel market is enormous and consistently underserved. Companies relocating staff, consultancies housing project teams, and international firms needing temporary executive accommodation all create steady demand for well-managed serviced apartments in zones one and two.

Corporate bookings tend to be longer (two weeks to six months is typical), more predictable, and significantly less management-intensive than nightly tourist stays. They also command premium rates when the property is positioned correctly. A one-bedroom apartment in Westminster that might earn £150 per night from tourists could generate £180 to £220 per night on a four-week corporate booking, with far lower vacancy rates and reduced wear and tear.

What Corporate Clients Expect

Business travellers have specific requirements that set the bar higher than weekend leisure guests:

• Fast, reliable Wi-Fi (non-negotiable)
• A proper workspace or desk area
• Consistent, hotel-standard cleaning and linen changes
• Self-check-in with 24/7 support
• Invoicing and corporate billing capabilities
• Locations near transport hubs and business districts

If your property ticks these boxes, you're competing in a market segment where supply is thinning while demand holds strong.

Understanding the Enforcement Landscape

Let's talk about what Westminster's crackdown actually looks like in practice, because getting this wrong can be costly.

Under the Deregulation Act 2015, you can let a residential property on a short-term basis for up to 90 nights per calendar year without planning permission. Exceed that limit, and you're technically in breach of planning law. Westminster has been one of the most aggressive boroughs in enforcing this, using data from booking platforms and even employing monitoring technology to identify repeat offenders.

Penalties can include enforcement notices, fines, and in serious cases, prosecution. The council has also been lobbying central government for stronger powers, including the ability to force platforms to automatically block listings that hit the 90-day cap.

How to Stay Compliant

There are several routes to running a legal, year-round SA operation in Westminster and other London boroughs:

1. Apply for planning permission for a change of use to temporary sleeping accommodation (Use Class C1 or sui generis). This is achievable but not guaranteed, particularly in residential buildings.
2. Focus on stays over 90 days per guest, which typically falls outside the short-term let definition and into standard tenancy territory.
3. Blend short-term and mid-term bookings to stay within the 90-day limit while maximising yield through corporate mid-term lets for the remainder of the year.
4. Use properties with existing commercial or mixed-use consent, which may already permit short-term accommodation.

Navigating these options requires expertise. A wrong assumption about your planning status could expose you to enforcement action, which is exactly why so many landlords in central London are turning to professional management partners like Airhosts to handle compliance alongside day-to-day operations.

The Pitfalls of Going It Alone

Serviced accommodation can deliver outstanding returns, but it's not a passive investment in the way that traditional buy-to-let can sometimes be. Running a compliant SA operation means managing bookings across multiple platforms, coordinating professional cleaning teams, handling guest communications around the clock, maintaining quality standards, tracking your 90-day usage, and keeping up with evolving regulations.

For landlords with one or two properties, the operational overhead can quickly eat into those higher yields. You might find yourself spending evenings responding to guest queries or weekends coordinating turnovers. The strategy works brilliantly at scale or with professional support, but it can become a second job if you try to manage everything yourself.

The Simpler Path to High-Yield, Hands-Off Income

This is where the comparison becomes really clear. The complexity of self-managing a compliant serviced accommodation operation, from regulatory tracking to corporate client acquisition to round-the-clock guest support, is significant. But the returns from short-term and mid-term letting in central London remain far superior to traditional tenancies, often delivering 30% to 60% more gross revenue.

The solution isn't to avoid the strategy. It's to let someone else handle the complexity while you keep the returns.

At Airhosts, this is exactly what we do for London landlords every day. We manage the entire short-term let operation from end to end: platform optimisation, dynamic pricing, professional housekeeping, guest vetting, 24/7 communication, and full regulatory compliance.

Our landlords don't worry about 90-day tracking, planning applications, or midnight guest messages. They receive their monthly income and watch their property outperform the market.

The Window Is Open, But It Won't Stay Open Forever

Westminster's crackdown is reshaping the short-term let market in real time. As amateur operators exit, professionally managed properties will capture a larger share of both tourist and corporate demand. Rental premiums in compliant, well-managed serviced accommodation are already rising, and this trend will only accelerate as enforcement tightens further.

If you own property in central London and you're still renting it on a standard AST, or if you're trying to self-manage a short-term let and feeling the pressure of increasing regulation, now is the time to act.
