Mid-Term Rentals Are Booming in London: How the Renters' Rights Act Is Creating a Lucrative New Niche for Landlords

A Seismic Shift Is Reshaping London's Rental Market

With just weeks to go before the Renters' Rights Act takes full effect on 1 May 2026, London's lettings landscape is undergoing one of its most significant transformations in a generation. The headline change? The complete abolition of fixed-term assured shorthold tenancies (ASTs). From next month, every new private tenancy in England will be periodic by default — and tenants will be able to leave with just two months' notice.

For many landlords, this feels like a loss of control. But beneath the uncertainty, a fascinating market dynamic is emerging. A growing class of "in-between" tenants — corporate relocators, insurance-displaced households, digital nomads, and contract professionals — are actively avoiding the traditional rental market altogether. Instead, they're seeking furnished mid-term lets of one to three months, and they're willing to pay a premium for them.

This is creating a genuine opportunity for London landlords who understand the niche. But it's also a market that demands operational sophistication. Let's break down exactly what's happening, how mid-term rentals work, and what you need to know before diving in.

Why the Renters' Rights Act Is Fuelling Mid-Term Rental Demand

The logic is straightforward. Under the new legislation, tenants on periodic tenancies can serve two months' notice and leave at any time. For landlords offering traditional long lets, this introduces a new layer of void risk — a tenant who signs up in January could be gone by April.

But here's the flip side: many tenants don't actually want an open-ended periodic tenancy either. Relocating professionals arriving in London for a three-month project don't want the administrative burden of setting up a tenancy they'll immediately need to unwind. Insurance companies housing displaced families after a flood or fire need guaranteed accommodation for defined periods. Corporate contractors want move-in-ready, fully furnished spaces without the friction of utility setup, council tax registration, and furniture sourcing.

These tenants are falling through the cracks of the traditional AST market — and landing squarely in the mid-term rental space.

What Exactly Are Mid-Term Rentals?

Mid-term rentals typically refer to furnished lettings lasting between one and six months, though the sweet spot in London tends to be one to three months. They sit in the gap between short-term holiday lets (often under 28 days) and traditional long-term tenancies.

Key characteristics include:

• Fully furnished and equipped — tenants expect hotel-level readiness, including linens, kitchenware, Wi-Fi, and often utilities included in the rate
• Flexible booking terms — often arranged through platforms like Airbnb, Booking.com, Spotahome, or corporate relocation agencies rather than traditional letting agents
• Higher nightly or weekly rates — mid-term lets typically command 20–40% more per month than equivalent unfurnished long lets, compensating for shorter occupancy periods
• Different regulatory treatment — stays over 90 consecutive nights in London generally fall outside the 90-day short-term letting cap, meaning landlords can operate year-round without planning permission concerns

Who's Booking Mid-Term Lets in London Right Now?

The demand pool is broader than many landlords realise:

• Corporate relocators and project-based professionals moving to London for defined contract periods
• Insurance-displaced tenants (known as "decant" housing) placed by loss adjusters and insurers, often with guaranteed payment
• International professionals testing London living before committing to a long-term tenancy
• Digital nomads and remote workers spending one to three months in the capital
• Families between property transactions — selling one home and awaiting completion on another

At Airhosts, we've seen enquiries from corporate and insurance channels increase by over 35% in the first quarter of 2026 alone — a trend directly correlated with uncertainty around the new tenancy framework.

The Pros and Cons Landlords Need to Weigh

The Upside

• Higher yields: A well-managed mid-term let in zones 1–3 can generate 30–50% more annual revenue than a traditional long let, even accounting for occasional void periods.
• Flexibility: You retain the ability to use your property, adjust pricing seasonally, or pivot strategies without navigating complex eviction procedures.
• Quality tenants: Corporate and insurance bookings often come with employer or insurer guarantees, reducing payment risk significantly.
• Regulatory clarity: Stays exceeding 90 nights avoid the short-term let planning restrictions that apply in many London boroughs.

The Challenges

• Operational intensity: Mid-term lets require professional cleaning between guests, linen management, maintenance responsiveness, and guest communication — far more than a traditional tenancy.
• Furnishing and setup costs: Expect to invest £5,000–£15,000 in quality furnishing, depending on property size, plus ongoing replacement costs.
• Platform management: Maximising occupancy means listing across multiple channels, managing dynamic pricing, handling enquiries promptly, and maintaining high review scores.
• Compliance complexity: You'll need to navigate HMO rules (if applicable), safety regulations, insurance requirements, and potentially business rates rather than council tax for certain let types.
• Void risk: Without a robust booking pipeline, gaps between tenancies can erode your yield advantage quickly.

The Operational Reality: Why Most Landlords Struggle to Self-Manage

Here's where many landlords hit a wall. The mid-term rental niche is genuinely lucrative — but it's operationally closer to running a hospitality business than managing a buy-to-let. You're not just a landlord; you're a host, a revenue manager, a cleaner coordinator, and a concierge.

Self-managing a mid-term let means responding to booking enquiries within minutes (not hours — platforms penalise slow responses), coordinating professional cleans to tight turnaround schedules, handling check-ins and key exchanges, resolving maintenance issues in real time, and continuously optimising your pricing against market demand.

For landlords with one property and a full-time job, this quickly becomes unsustainable. For portfolio investors, it's virtually impossible without a dedicated team.

The Smarter Path: Professional Short-Term Let Management

This is precisely why an increasing number of London landlords are choosing to hand the entire operation to a specialist management company — and why professionally managed short-term lets consistently outperform self-managed mid-term rentals on both yield and hassle.

With a professional partner like Airhosts, you get the best of every world:

• Multi-platform listing and optimisation across Airbnb, Booking.com, Vrbo, and corporate channels — capturing short-term, mid-term, and corporate demand simultaneously
• Dynamic pricing technology that adjusts rates daily based on London market conditions, local events, and seasonal patterns
• Full guest management from enquiry to checkout, including 24/7 communication, key exchange, and concierge support
• Professional housekeeping and linen services with quality-controlled turnovers between every stay
• Regulatory compliance management, ensuring your property meets all safety, licensing, and local authority requirements
• Revenue reporting and transparency, so you always know exactly what your property is earning

Rather than limiting yourself to mid-term bookings alone, a professionally managed short-term let captures the full spectrum of London demand — from weekend leisure guests paying peak nightly rates to three-month corporate relocators on negotiated monthly terms. This blended strategy typically delivers the highest annual yield of any residential letting approach in London.
