Rent tribunal cases surge as tenants challenge rent increases
Since the Renters’ Rights Act came into force this year, rent tribunal cases have risen sharply, with tenants initiating most disputes. Tribunal decisions on market rent nearly quadrupled in July compared to the previous year.
Legal experts and letting agents report a significant increase in rent disputes reaching property tribunals since the introduction of the Renters’ Rights Act. According to data from letting agency Hamptons, tribunals made 166 market rent decisions in July 2026, almost four times the 44 decisions recorded in July 2025. This surge follows a steady monthly average of 42 decisions up to April 2026, rising to 109 in May and 129 in June.
Tenants have been responsible for initiating approximately 60% of these recent cases. The Act’s provisions have made challenging rent increases more accessible and less risky for tenants. If a tribunal approves the landlord’s proposed rent, the tenant pays the higher amount from the date of the decision, not retroactively from the landlord’s original request, reducing potential backdated liabilities for tenants.
Tribunal data and expert analysis on rent challenges
Paul Rooke, partner at Mayo Wynne Baxter, interprets the tribunal data as evidence that the Renters’ Rights Act has shifted the balance of power towards tenants. He highlights that the removal of section 21 ‘no-fault’ evictions and the elimination of backdated rent liability risks have lowered barriers for tenants to contest rent increases. Rooke stresses that landlords can no longer justify rent hikes solely by citing increased costs. Instead, any proposed increase must be backed by robust evidence of market rent, including comparable local lettings, property condition, location, amenities, and recent rental transactions.
Rooke advises landlords to maintain a clear audit trail documenting how rent figures were determined and to ensure strict compliance with the statutory section 13 process. He anticipates that rent challenges will become a significant category of disputes between landlords and tenants. Although tribunals are currently managing the increased caseload with improved processing times, a sustained rise in applications could strain a system already handling service charge, leasehold, and other property disputes.
Kristine Ng, partner at Morr & Co, concurs that the rise in tribunal challenges is unsurprising given current market conditions. She notes that many landlords seek rent increases to reflect market realities, while tenants face affordability pressures and are more willing to question the justification for such increases. Ng points out that while the right to challenge rent increases is not new, the Renters’ Rights Act has amplified the prominence of these disputes. The abolition of section 21 evictions and changes to the financial consequences of challenges have encouraged tenants to test whether proposed rent increases genuinely reflect market rent.
Ng emphasises that tribunals focus on market rent rather than landlords’ increased costs. Even if landlords have legitimate reasons for raising rents, the tribunal’s concern is the rent the property could reasonably achieve on the open market. She advises landlords to support any proposed increase with evidence of comparable local lettings and prevailing market conditions. As tenant awareness of these rights grows, rent determination cases are expected to become a more prominent feature in the residential landlord and tenant landscape, increasing demands on tribunal resources.
Implications for landlords and letting agents
For landlords and agents, the rise in rent tribunal cases signals a need for greater diligence in rent review processes. The Renters’ Rights Act has removed some traditional deterrents for tenants to challenge rent increases, making it essential for landlords to prepare thoroughly. Evidence-based rent proposals supported by recent comparable lettings and clear documentation will be crucial in defending rent increases at tribunal.
Landlords must ensure compliance with the statutory section 13 process, which governs how rent increases are formally proposed and notified. Failure to follow this process correctly can jeopardise the landlord’s position in a tribunal. Maintaining detailed records of how rent figures are calculated, including market research and property condition assessments, will help landlords demonstrate the reasonableness of their proposals.
Letting agents should advise landlords on the importance of robust evidence and procedural compliance. They may also need to prepare for an increased volume of rent disputes and the associated administrative and legal workload. The tribunal system’s current capacity to handle the surge is encouraging, but ongoing growth in cases could lead to delays and increased costs.
Challenges and uncertainties ahead
While the Renters’ Rights Act has empowered tenants, it has also introduced complexities for landlords. The focus on market rent rather than cost increases means landlords must be more strategic and evidence-focused when proposing rent changes. The evolving tribunal caseload may lead to further procedural refinements or guidance to manage demand and ensure fair outcomes.
Uncertainty remains over how tribunals will handle borderline cases and the consistency of decisions across different regions. Landlords should monitor tribunal outcomes closely to understand emerging trends and adapt their rent review strategies accordingly. There is also potential for increased pressure on tribunal resources, which could affect case processing times and landlord-tenant relations.
What landlords should consider now
- Review and strengthen rent review procedures to ensure full compliance with section 13 requirements.
- Gather and maintain comprehensive evidence of market rents, including recent comparable lettings and property condition reports.
- Document all communications and decisions related to rent proposals to create a clear audit trail.
- Prepare for the possibility of increased rent challenges and consider legal advice or specialist support when disputes arise.
- Stay informed about tribunal decisions and regulatory developments affecting rent reviews and tenancy rights.
