Navigating the 2026 Tenancy Law Shift: How Letting Agents in Corsham Keep Your SN13 Portfolio Compliant

For landlords in Corsham, 2026 has brought some of the biggest changes to private renting in years. The Renters’ Rights Act 2025 introduced new rules from 1 May 2026, changing how tenancies operate, how rents can be increased and how landlords regain possession. For letting agents in Corsham, helping landlords understand and adapt to these changes has become an increasingly important part of effective property management.

With Corsham house prices averaging £395,620 over the last year, protecting both the value and income potential of a property portfolio is more important than ever. From managing changing tenancy arrangements to keeping up with statutory requirements, landlords need a reliable approach to compliance. Working with experienced letting agents in Corsham can help reduce the risk of costly mistakes while keeping your SN13 portfolio running smoothly.

1. Moving to Periodic Tenancies: What the End of Fixed Terms Means for Your Corsham Property

One of the biggest changes is the end of fixed-term assured tenancies.

From 1 May 2026, assured tenancy agreements can no longer have a fixed term or set end date. Existing assured shorthold tenancies automatically become Assured Periodic Tenancies, with the tenancy continuing on a rolling basis. The rental period will usually be monthly unless the agreement specifies a shorter period.

For landlords, this means the traditional approach of waiting for a fixed term to expire before deciding what happens next is no longer appropriate.

Tenant flexibility can also influence turnover and void periods. Landlords should therefore review their tenancy records, understand the new notice arrangements and plan ahead for potential changes in occupancy.

2. Issuing Rent Increases Legally: Understanding Section 13 Notices

Rent reviews have also changed.

After 1 May 2026, landlords cannot rely on rent review clauses in existing tenancy agreements for new increases. Instead, rent increases must follow the Section 13 process under the Housing Act 1988. Landlords can increase rent only once a year and must provide at least two months’ written notice using Form 4A. The proposed rent must not exceed the open market rent.

For Corsham landlords, understanding the local market is therefore particularly important. With average sold prices rising by 4% over the last year, and properties achieving different values depending on type, landlords should still base rental decisions on the current rental market rather than simply applying a percentage increase.

A well-evidenced rent review can help reduce the likelihood of disputes and ensure the increase is properly managed.

3. Avoiding Costly Compliance Mistakes

The 2026 changes make accurate tenancy records increasingly important.

If a tenant does not have a written tenancy agreement or written record of the tenancy terms, the landlord must provide certain written information by 31 May 2026. The new legal rules also apply automatically, even where the tenancy agreement has not been updated.

Landlords should therefore review:

• Existing tenancy agreements and records
• Rent increase procedures and notices
• Deposit documentation
• Statutory safety records
• Required tenant information
• Possession notices and supporting evidence

Getting the paperwork wrong can create significant complications if a landlord later needs to recover possession.

4. Protecting Your Investment: Why Professional Letting Agents in Corsham Can Help

The end of Section 21 notices is another major change. From 1 May 2026, landlords cannot use Section 21 to end a tenancy without a legal reason. Instead, they must rely on a valid Section 8 possession ground and follow the required notice process.

For landlords managing multiple properties, keeping track of these requirements can quickly become an administrative burden.

A professional letting agent can help by reviewing tenancy documentation, managing rent reviews, monitoring statutory obligations and ensuring possession procedures are handled correctly.

Local expertise can also be valuable. Corsham’s property market includes a broad mix of homes, with semi-detached properties averaging £380,450, detached properties £520,408 and terraced properties £311,682 over the last year. Understanding the local market alongside the changing legal framework helps landlords make better-informed decisions.

Staying Compliant in a Changing Rental Market

The 2026 tenancy reforms mean landlords need to be more proactive about compliance. From periodic tenancies and Section 13 rent increases to possession procedures and tenant information, relying on old processes could leave your portfolio exposed.

For Corsham and SN13 landlords who want professional support managing these responsibilities, working with experienced local letting specialists can provide greater confidence and help keep day-to-day property management on track.
