September saw a seasonal slowdown in applicant demand, with 32% fewer registrations month-on-month. However, rental values remained strong, with average rents reaching nearly £600 per week, the highest September figure in four years. Increased stock levels and resilient applicant budgets suggest a more balanced market is emerging across London.
Looking ahead, landlords should prepare for the upcoming Renters’ Rights Act, due to take effect from 2026. Key changes include the end of Section 21 “no-fault” evictions, the introduction of rolling tenancies, and stricter rules around rent increases and property standards. A new national landlord register and compliance framework will also be introduced in a second implementation phase.
Foxtons is actively supporting landlords through these changes, ensuring properties remain compliant and well-managed. If you have questions about how the reforms may affect your portfolio, our team is here to help.
