Rents set to rise sharply as UK rental supply declines

Rents across the UK are projected to increase by up to 5% by the end of 2026 due to a fall in rental supply and sustained demand, driven in part by rising mortgage rates affecting first-time buyers.

Rents are climbing again after a period of slower growth during 2024 and 2025, with the latest Zoopla Rental Market Report highlighting a decline in available rental properties as a key factor. This trend is impacting landlords, letting agents and tenants alike, as the balance between supply and demand tightens.

The report shows that since May 2026, the number of homes available to rent has decreased, ending a three-year period where supply had been recovering and helping to moderate rent increases. By August 2026, rental supply was down 6% compared to the previous year, with an overall 3% reduction in homes for rent across the UK. This decline is particularly pronounced in regions experiencing faster rental growth, such as London and Yorkshire and Humberside.

Zoopla data reveals regional rental market disparities

London stands out as an area where both rental demand and supply are tightening simultaneously. The capital has seen rental growth accelerate to 2.9% year-on-year, up from 1.7% the previous year. This is linked to mortgage rate rises that have significantly increased the deposit required for first-time buyers in London—an average additional £35,500 compared to £18,200 nationally—keeping more prospective buyers renting for longer.

Inner London postal areas (SE, E, N, NW, SW, W, EC, WC) have seen rental supply fall by 13%, while demand has increased, pushing rental growth to between 3% and 4% in these zones. Outside London, the Yorkshire and Humberside region has also experienced a steep drop in rental supply (down 12%) alongside rising rents. Conversely, Wales has bucked the trend with a 7% increase in rental supply, which has eased rental inflation there.

The rental market continues to exhibit a two-speed nature. Lower-rent areas (under £750 per calendar month) are seeing rent rises of around 5.4%, roughly double the national average of 2.6%. These more affordable markets, often in northern England and Scotland, have fewer landlords and lower investment levels, contributing to sharper rent increases. Meanwhile, the highest-value areas are also experiencing faster rent growth due to London’s influence, although affordability constraints limit how far rents can rise.

Mortgage rates and investment levels shape rental market dynamics

Mortgage rates have increased since early 2026, reducing homeownership prospects for many and keeping renters in the market longer. This sustained demand, combined with falling rental supply, has increased competition for available properties. The average number of enquiries per rental listing has risen to 5.3, the highest level in nearly two years, indicating growing pressure on available stock.

Investment in new rental properties by landlords remains subdued due to higher costs and increased regulation, limiting the growth of rental stock. This lack of new supply is a significant factor pushing rents upwards. Zoopla anticipates that rents will rise between 4% and 5% by the end of 2026, aligning more closely with earnings growth after a period of slower increases.

Richard Donnell, Executive Director at Zoopla, emphasises that the rental market is highly sensitive to changes in supply and demand. He points out that increasing the number of homes available to rent through greater investment is the most sustainable way to stabilise rents and improve choice for tenants over the long term.

Implications for landlords and letting agents

For landlords, the tightening rental market presents both opportunities and challenges. Higher rents can improve income streams, but increased competition for tenants may require careful management of property standards and tenant relations to minimise void periods. Letting agents should prepare for heightened demand and enquiries, ensuring efficient processes for tenant vetting and property marketing.

Landlords should also be mindful of affordability constraints impacting tenants, particularly in higher-rent areas, to avoid rent arrears and turnover. The regional variations in supply and demand mean that local market knowledge will be crucial for setting competitive rents and managing portfolios effectively.

As regulatory and cost pressures continue to affect landlord investment decisions, those with existing rental stock may find themselves in a stronger position if they maintain properties well and respond to tenant needs promptly. However, the ongoing scarcity of rental homes underlines the importance of compliance with safety and licensing regulations to avoid penalties and reputational damage.

What remains uncertain in the rental market outlook

While the current data points to rising rents and reduced supply, the longer-term impact of government policies, potential changes in mortgage rates, and evolving tenant behaviour remain uncertain. The Renters’ Rights Act and other regulatory reforms may influence landlord and tenant dynamics, but Zoopla’s analysis suggests these are not the primary drivers of current rental inflation.

Landlords and agents should monitor official guidance and market developments closely. Changes in economic conditions, such as wage growth or interest rate adjustments, could alter affordability and demand patterns. Additionally, shifts in landlord investment appetite or new housing supply initiatives might affect rental stock availability in the future.

Considerations for landlords amid rising rents and tightening supply

• Review and update rental pricing strategies regularly to reflect local market conditions and affordability constraints.
• Maintain high standards of property maintenance and compliance to attract and retain tenants in a competitive market.
• Keep thorough records of rent reviews, tenant communications and property inspections to support effective management and potential dispute resolution.
• Stay informed about regional licensing requirements and safety obligations to avoid fines and enforcement action.
• Plan for potential increased demand and enquiries by streamlining tenant vetting and application processes.

Supporting landlords through market changes with TLA resources

The Landlord Association (TLA) offers members access to compliance resources and practical guidance that can help landlords and letting agents manage portfolios effectively during periods of market change. TLA’s new property management and compliance platform, ORBIT, currently in BETA testing, is designed to assist with organising property records, managing rental documentation, and recording key actions such as inspections and communications.

ORBIT’s development aims to support landlords in maintaining evidence of compliance with safety and licensing requirements, which is increasingly important as regulatory scrutiny intensifies. Members can explore TLA membership options to access tailored compliance support and keep up to date with evolving rental sector regulations.

By utilising these resources, landlords and agents can better prepare for the operational demands of a tightening rental market and ensure they meet their legal obligations while optimising portfolio performance.

Looking ahead, the rental market is expected to remain challenging, with rising rents and limited supply. Landlords should stay vigilant to regulatory changes and market signals to adapt their strategies accordingly.
