Buy-to-let (BTL) borrowers are currently facing uncertainty as lender guidance struggles to keep pace with recent legislative changes. Following the introduction of the Renters’ Rights Act on May 1, 2026, significant alterations to tenancy laws have left many landlords in a state of confusion regarding their mortgage conditions.

What has changed with the Renters’ Rights Act?

The Renters’ Rights Act has abolished the assured short-hold tenancy (AST) in England and Wales, converting all existing ASTs to assured periodic tenancies. This shift means that landlords can no longer issue fixed-term tenancies, and possession can only be sought on statutory grounds outlined in the Housing Act 1988. This has significant implications for BTL landlords who must now navigate a more complex legal framework.

How does this impact buy-to-let mortgages?

The changes brought by the Renters’ Rights Act directly affect the practical experience of being a landlord. Many BTL mortgage conditions were established when ASTs were the norm, and as a result, some lenders have not updated their guidance to reflect the new legal realities. For instance, Lloyds Bank continues to reference ASTs in its customer-facing BTL guidance, potentially misleading borrowers who are now subject to different tenancy regulations.

What should landlords do now?

Landlords are advised to consult their mortgage brokers or lenders directly to obtain written confirmation that their periodic tenancies comply with the new Act. This step is important to ensure that landlords are not inadvertently breaching their mortgage conditions due to outdated lender guidance. The inconsistency in lender updates highlights the importance of proactive communication between landlords and their financial representatives.

What this means for landlords and investors

For landlords and investors in the buy-to-let market, these changes necessitate a careful review of existing tenancy agreements and mortgage conditions. The shift to assured periodic tenancies may affect rental income stability and the ability to evict tenants. Investors should remain vigilant about lender communications and seek clarity on how their mortgage products align with current legislation. Understanding these changes will be vital for maintaining compliance and optimising rental yields.

Frequently asked questions

What are assured periodic tenancies?

Assured periodic tenancies are a new form of tenancy that automatically applies to existing assured short-hold tenancies following the Renters’ Rights Act. They do not have a fixed term and can only be terminated under specific statutory grounds.

How can I ensure my BTL mortgage is compliant?

To ensure compliance, landlords should contact their mortgage broker or lender for written confirmation that their periodic tenancy meets the requirements of the Renters’ Rights Act. This will help avoid potential issues with mortgage conditions.
