Rent Tribunals Are Slashing Landlord Increases Post-RRA: Why Mid-Term Rentals Sidestep the Ceiling Entirely

Tribunals Are Blocking the Rent Increases London Landlords Need

The numbers are in, and they're sobering. According to Property Industry Eye, analysis of 667 tribunal decisions since May 2026 shows a clear pattern: landlords requesting significant rent increases under the Renters' Rights Act are having them slashed by tribunals. The average requested increase sits around 14%, but tribunals are consistently cutting these down, sometimes dramatically.

Combine that with the new 24 to 49% property income tax rates arriving in April 2027, and the picture for traditional AST landlords in London is getting uncomfortably tight. Costs are rising, rental income is being capped by tribunal ceilings, and the margins that once made buy-to-let attractive are shrinking fast.

So what are savvy London landlords doing about it? A growing number are turning to mid-term rentals, a strategy that sidesteps the tribunal mechanism entirely. Let's explore how this works, why it matters right now, and what you need to know before making the switch.

What Exactly Are Mid-Term Rentals?

Mid-term rentals occupy the space between traditional long lets and short-term holiday stays. Typically ranging from one to six months, these lettings serve a specific and growing market: corporate relocations, medical professionals on placement, academics on sabbatical, families between homes, and international workers on project-based assignments.

Unlike an Assured Shorthold Tenancy, a mid-term rental operates on a contractual licence or a short fixed-term agreement. The key distinction here is that mid-term lets, when structured correctly, fall outside the scope of the Renters' Rights Act and its tribunal mechanism for rent disputes.

This means you set your price based on market demand, not based on what a tribunal panel decides your property is worth relative to comparable rents in the area.

Why Mid-Term Rentals Avoid the Tribunal Ceiling

The rent tribunal process under the RRA applies specifically to periodic assured tenancies. When a landlord proposes a rent increase, tenants can challenge it, and the tribunal determines whether the proposed rent reflects open market value. In practice, tribunals have been conservative, often anchoring to existing rent levels and making modest adjustments.

Mid-term rentals operate on a fundamentally different basis. Each letting is a new agreement at a new price. There is no sitting tenant disputing an increase because the tenancy concludes at the end of its fixed term. You are free to price your next booking according to current demand, seasonality, and your own financial needs.

For London landlords watching their AST rental income fall behind rising mortgage costs, insurance premiums, and the looming tax changes, this flexibility is genuinely meaningful.

The Real Advantages for London Landlords

Pricing Freedom

You set the rate for each booking. If demand is strong in your area, you capture that value immediately rather than waiting 12 months to propose an increase that might get rejected.

Higher Gross Yields

Mid-term rentals in London typically command a 20 to 40% premium over equivalent long-term AST rents. Furnished properties in well-connected zones can perform even better, particularly for corporate tenants who value move-in-ready convenience.

Reduced Wear and Tear Risk

Shorter stays mean more frequent inspections and turnovers. You catch maintenance issues early and keep the property in better condition over time.

Tenant Quality

The mid-term market attracts professional tenants, often with employer-backed budgets. Payment reliability tends to be high, and the contractual framework gives you more control over occupancy terms.

The Pitfalls You Need to Watch

Mid-term rentals are not without their challenges, and it would be dishonest to pretend otherwise.

Void Periods

Unlike a long-term AST where rent flows continuously, mid-term lets carry the risk of gaps between bookings. Poor marketing or incorrect pricing can leave your property sitting empty during shoulder periods.

Operational Complexity

Each new tenancy requires onboarding: cleaning, inventory checks, key handovers, contract preparation, and tenant vetting. Multiply that across six or more tenancies per year and the admin burden grows significantly.

Furnishing and Setup Costs

Mid-term tenants expect a fully furnished, well-equipped property. The upfront investment in quality furniture, linens, kitchen supplies, and reliable Wi-Fi is real. A poorly furnished property simply will not compete.

Regulatory Awareness

Some London boroughs have specific rules around short and mid-term lets. While most mid-term arrangements (30 days or longer) fall outside the 90-day short-term let rule, you need to understand your local authority's position and ensure compliance.

Consistent Marketing

You cannot just list a property and hope for the best. Success in the mid-term space requires active listing management across multiple platforms, dynamic pricing adjustments, and fast response times to enquiries. This is where many self-managing landlords struggle.

When Self-Management Becomes the Real Problem

Here is where many landlords reach a crossroads. The mid-term rental model clearly offers better income potential and freedom from tribunal constraints. But the operational demands can quickly consume your time, especially if you own multiple properties or have other professional commitments.

The most common mistake we see at Airhosts is landlords who recognise the opportunity but underestimate the workload. They start strong, then booking gaps appear, cleaning standards slip, and the premium income they expected fails to materialise.

This is also why many landlords exploring mid-term lets eventually discover that professionally managed short-term lets deliver even stronger returns with less personal involvement.

Short-Term Lets: Higher Returns, Fully Managed

Short-term lets in London, when managed professionally, consistently outperform both traditional ASTs and self-managed mid-term rentals. Nightly rates capture peak demand periods, holiday surges, and event-driven pricing that monthly rates simply cannot match.

The perceived complexity of short-term lets, guest communications, cleaning schedules, dynamic pricing, platform management, regulatory compliance, is exactly why professional management exists. When someone else handles all of that, you are left with the income and none of the operational headaches.

Airhosts manages the entire process for London landlords: listing optimisation, professional photography, guest screening, 24/7 communication, cleaning coordination, pricing strategy, and full regulatory compliance. Our landlords earn more while doing less, which is exactly the point.

The Clearest Path Forward for London Landlords

The traditional AST model is under genuine structural pressure. Tribunal ceilings are capping your income at a time when costs are accelerating, and the April 2027 tax changes will squeeze margins further. Mid-term rentals offer a meaningful improvement, but they demand active management and carry operational risks that can erode the premium if you are not set up properly.

Professionally managed short-term lets combine the pricing freedom of mid-term rentals with higher yield potential and a truly hands-off experience.
