Rental Growth Peaks in May 2026: What London Landlords Need to Know

Strongest Rental Growth in 2026: A Snapshot

May 2026 saw UK rents rise by 1.1% compared to April, marking the strongest monthly rental growth so far this year. On a year-on-year basis, rents climbed by 2.5%, with Greater London and Scotland experiencing the sharpest increases. For London landlords, where rental demand remains high, this signals a clear upward trend in achievable rent — but also raises concerns around tenant affordability and tenancy sustainability.

Why This Matters: Balancing Income and Affordability

Rising rents can bolster landlord income and portfolio yields, but the flipside is increased financial pressure on tenants. In London, where living costs are already elevated, pushing rents too high risks tenancy turnover, arrears, or longer void periods. Sustainable tenancies depend on setting rents that reflect market conditions without exceeding what local tenants can realistically afford.

Practical Implications for Different Landlord Profiles

• Single-Unit Landlords: A modest rent increase aligned with the 1.1% monthly growth may be appropriate, but ensure any uplift doesn’t price out current tenants at lease renewal.
• HMO Landlords: Given higher turnover in HMOs, incremental rent rises should be balanced with the costs of tenant sourcing and void periods.
• Portfolio Landlords: With multiple properties, consider region- and property-specific rent reviews to optimise income while maintaining high occupancy.
• Accidental Landlords: If managing property alongside other commitments, prioritise clear rent review schedules and tenant affordability checks to avoid unexpected arrears.

Action Steps to Take Now

1. Review Your Current Rents: Compare your portfolio’s current rents against the latest market data for London and specific boroughs. Use sources like the RICS UK Residential Market Survey or local letting agent reports to benchmark effectively.

2. Assess Tenant Affordability: Strengthen tenant referencing procedures to include thorough income verification and affordability assessments. This reduces risks of arrears and ensures tenants can sustain rent increases.

3. Consider Rent Guarantee Insurance: This can provide a safety net against unpaid rent or tenancy defaults, particularly valuable given the medium risk level associated with rising rents.

4. Communicate with Tenants: When proposing rent increases, provide clear explanations tied to market evidence to foster goodwill and reduce disputes.

5. Monitor Market Trends: Set a quarterly reminder to review rent indices and local market conditions. This proactive approach helps you adjust strategies before lease renewals.
