September 2026 Lettings Market Update: What Every Landlord Needs to Know
The UK rental market is entering a period of significant change. Rising rents, falling rental supply, increasing tribunal challenges and the continued rollout of the Renters' Rights Act are reshaping the landscape for landlords, tenants and letting agents alike.
In this month's lettings market update, James Richards of Maddisons Residential examines the latest headlines affecting the private rented sector, including rent control debates, growing affordability pressures, changes to rent increase challenges, the rise of guarantor requirements and the new national landlord database.
Whether you own a single buy-to-let property or a larger portfolio in Tunbridge Wells, Kent or the wider South East, understanding these changes is essential to protecting your investment and staying ahead of future regulation.
Is the Renters' Rights Act already affecting landlords?
Yes.
Although many landlords were initially focused on the headline changes, we are now starting to see real-world effects. Tenant challenges to rent increases have increased significantly, affordability assessments are becoming more important, and many landlords are adopting additional safeguards such as guarantors and rent guarantee products. The legislation is already changing the way rental property is managed across England.
Can tenants now challenge rent increases more easily?
Yes.
Under the new legislation, tenants are more willing to challenge rent increases through the tribunal process. As a result, landlords should ensure that any rent review is supported by clear market evidence, including comparable local rental properties and accurate rental valuations.
Why are rents continuing to rise in 2026?
The main reason is the ongoing imbalance between supply and demand.
Demand for quality rental property remains extremely strong, while the number of available homes to rent has started to decline. Higher mortgage rates are also keeping many prospective buyers in the rental sector for longer, increasing competition for available stock.
What is the new landlord database and do landlords need to register?
The Government is introducing a national landlord database as part of the wider reforms affecting the private rented sector.
The intention is to improve transparency, support compliance and make it easier for tenants to verify that landlords are meeting their legal obligations. Landlords should expect registration requirements and ongoing compliance responsibilities to become a routine part of property ownership.
Should landlords be concerned about rent controls?
At present, the Government has stated that it has no plans to introduce rent controls in England.
However, political debate on the subject continues. Many industry experts have warned that rent controls could reduce investment in the private rented sector, potentially leading to fewer homes being available to rent. As a result, the issue remains one of the most closely watched housing policy discussions in the UK.
Are landlords leaving the private rented sector?
A growing number of industry commentators believe increasing regulation, higher taxation and compliance burdens are causing some landlords to reconsider their long-term plans.
While many professional landlords continue to invest successfully, the focus is increasingly shifting towards efficiency, compliance and professional property management.
Is now a good time to invest in buy-to-let property in Kent?
Kent continues to benefit from strong tenant demand, excellent transport links and ongoing population growth.
While the regulatory environment has become more complex, quality rental properties in desirable locations continue to attract strong tenant interest and deliver long-term investment potential when professionally managed.
What should landlords do before the Renters' Rights Act is fully implemented?
Landlords should review tenancy agreements, rent review procedures, compliance records, affordability assessment processes and property management arrangements.
Seeking professional advice early can help avoid disputes, maintain compliance and protect long-term rental income.
