Fixed-Term to Periodic: How the New Tenancy Default Impacts Your Annual Yield

The implementation of the Renters' Rights Act has dismantled the traditional foundation of UK property investment: the assured short-hold tenancy (AST) fixed term. As of May 1st, 2026, all new and existing tenancies automatically default to a periodic (rolling) structure [1]. For landlords accustomed to the financial predictability of 6, 12, or 24-month fixed contracts, this shift requires a fundamental recalculation of how annual yield is projected and protected.

This legislative change effectively transfers the flexibility of tenure from the landlord to the tenant. Tenants can now issue a two-month notice to vacate at any point, removing the guaranteed income stream that fixed terms previously provided. For landlords in the Midlands—whether managing a single buy-to-let in Repton or a diverse portfolio across Burton and Birmingham—understanding the financial implications of this shift is critical to maintaining profitability in 2026.

The Financial Implications of Periodic Tenancies

The move to default periodic tenancies introduces new variables into your financial forecasting. It is no longer sufficient to simply multiply the monthly rent by 12 and deduct management fees. Landlords must now actively manage the increased risk of void periods and tenant turnover.

1. The Void Period Recalculation

Under the old fixed-term system, void periods were predictable. A landlord knew exactly when a contract was ending and could begin marketing the property weeks in advance, often securing a new tenant before the current one vacated.

With periodic tenancies, a tenant can give notice at any time. While the two-month notice period provides some buffer, the unpredictability makes scheduling refurbishments and marketing significantly more challenging. If a tenant gives notice in late October, you are suddenly faced with trying to let a property during the notoriously slow December period—a scenario that frequently results in extended voids.

2. The Cost of Increased Tenant Turnover

Tenant turnover is the silent killer of portfolio yield. Every time a property changes hands, the landlord incurs costs:

Marketing and Referencing Fees: Finding and vetting a new tenant.

Inventory and Check-Out Costs: Professional assessments of the property's condition.

Maintenance and Refresh: The inevitable "wear and tear" touch-ups required between tenancies (painting, deep cleaning, minor repairs).

Lost Rent: The days or weeks the property sits empty.

In a periodic tenancy environment, if your property management and tenant experience are sub-par, your turnover rate will increase, and these costs will compound, severely degrading your net annual yield.

3. Mortgage and Valuation Considerations

Lenders have traditionally favored the security of fixed-term ASTs. While the mortgage market is adapting to the Renters' Rights Act, some lenders are scrutinizing the cash flow stability of portfolios more closely [2]. Properties with high historical turnover rates under the new periodic system may face stricter lending criteria or less favorable rates when refinancing.

Retention Strategies in the Periodic Model

In a market where tenants can leave with two months' notice, tenant retention becomes the primary driver of financial stability. You can no longer rely on a contract to keep a tenant in place; you must rely on the quality of the product and the service.

Shifting from "Landlord" to "Service Provider"

At Stay & Co, we have always viewed property management as a hospitality business. The periodic tenancy model makes this approach mandatory. To protect your yield, you must implement proactive retention strategies:

1. Rapid-Response Maintenance: The number one reason tenants choose to leave a property is poor maintenance. Implementing a 24-hour response standard for all issues, and a 4-hour standard for emergencies, is critical.

2. Proactive Property Upgrades: Don't wait for a tenant to leave to improve the property. Offering strategic upgrades (e.g., a new appliance, fresh paint in a key room) at the 12-month mark can incentivize a tenant to stay long-term.

3. Professional Communication: Tenants expect clear, respectful, and responsive communication. A professional management team acts as a buffer, ensuring all interactions are handled efficiently and legally.

4. Fair and Transparent Rent Reviews: The Renters' Rights Act limits rent increases to once per year, and they must be fair and market-aligned. Communicating these reviews professionally, with clear market justification, prevents the "shock" that often triggers a tenant's notice to leave.

Case Study: The Cost of Complacency

Consider two identical properties in Burton, both renting for £1,000 per month.

Property A (DIY Managed, Reactive): The landlord is slow to fix a leaking tap. Frustrated, the tenant uses their new periodic rights to give two months' notice in month 8. The property sits empty for 3 weeks while the landlord handles the repair and finds a new tenant.

Cost: £750 (lost rent) + £300 (marketing/referencing) + £200 (repair) = £1,250 hit to annual yield.

Property B (Professionally Managed, Proactive): Stay & Co manages the property. A minor issue is reported and fixed within 24 hours. At month 11, we conduct a proactive check-in and arrange a minor touch-up. The tenant feels valued and stays for 3 years.

Cost: £0 in void periods. Consistent, predictable yield.

Frequently Asked Questions (FAQs) 

Q: What does "periodic tenancy" actually mean?

A: A periodic tenancy is a rolling contract (usually month-to-month) with no fixed end date. It continues until either the tenant gives notice or the landlord successfully applies for possession under specific legal grounds.

Q: Can I still ask a tenant to sign a 12-month fixed contract?

A: No. Under the Renters' Rights Act, any provisions relating to fixed terms have no legal effect after May 1st, 2026. All tenancies are treated as periodic.

Q: How much notice must a tenant give to leave?

A: Under the new rules, a tenant must provide a minimum of two months' notice to end the tenancy.

Q:  Can I still increase the rent on a periodic tenancy?

A: Yes, but rent increases are limited to once per year, and you must use the statutory Section 13 process, providing two months' notice of the increase.

Q:  How does this affect my buy-to-let mortgage?

A: Most major lenders have updated their criteria to accept periodic tenancies, as it is now the legal standard. However, you should consult with your broker, especially if you are refinancing a large portfolio.

Q:  Is there any way to guarantee a tenant stays for a year?

A: Legally, no. The only way to encourage long-term tenancies is through excellent property management, proactive maintenance, and fair rent pricing.

Q:  How does Stay & Co handle tenant retention?

A: We focus heavily on the "guest experience" even for long-term residential tenants. Our rapid-response maintenance, professional communication, and proactive property management systems are designed specifically to minimize turnover and protect your yield.

Q:  Should I consider short-term lets (SA) instead?

A: For some properties, converting to Serviced Accommodation (SA) can offer higher yields and different regulatory frameworks. Stay & Co can provide a feasibility study to see if this strategy suits your portfolio.
