Rental market
The rental market is the system through which residential properties are let by landlords to tenants in exchange for rent. It encompasses every aspect of the letting process, the supply of available homes, the demand from prospective tenants, the pricing mechanism that sets rent levels, and the regulatory framework that governs the relationship between landlord and tenant. In the UK, the rental market is most commonly discussed in the context of the private rented sector (PRS), which refers specifically to housing let by private individuals and companies rather than by local authorities or housing associations.
The rental market is sometimes used interchangeably with the private rented sector, though strictly the PRS refers to the sector itself (its participants, regulations, and tenure classification), while the rental market describes the economic dynamics of supply, demand, and pricing that operate within it.
The scale of the UK rental market
According to the English Housing Survey 2024-25 headline report published by MHCLG, the private rented sector accounted for 4.7 million households, 19% of all households in England, in 2024-25. This represents a near-doubling since the early 2000s, when the sector accounted for 9–11% of households. The sector has remained broadly stable at around 19–20% since 2013-14. Approximately 2.3 million private landlords operate in England, the majority of whom own one to five properties and self-manage at least part of their portfolio.
The rental market is the second largest housing tenure in England, ahead of the social rented sector (16% of households) but well behind owner occupation (65%). Private renters are more nationally diverse than other tenure groups and are spread more evenly across income quintiles than either mortgagors or social renters.
What drives supply and demand in the rental market
Rental market dynamics are shaped by the interaction between housing supply (the number of homes available to rent) and tenant demand (the number of households seeking rental accommodation).
On the demand side, the structural drivers are sustained and long-term. Homeownership affordability has declined significantly since the early 2000s, with high house prices and deposit requirements keeping a growing proportion of households in the rental market for longer. Demographic factors, including household formation rates, internal migration, and the concentration of younger workers in cities, add consistent demand in certain geographies. International net migration, which rose sharply after the pandemic before falling significantly in 2024-25, has been a particularly volatile demand driver in recent years.
On the supply side, the picture is more constrained. The number of private rented homes available has declined in many areas as landlords have sold or exited the sector in response to rising mortgage costs, tax changes (particularly the Section 24 mortgage interest restriction), and the growing regulatory burden. According to NRLA survey data cited by August's landlord blog, 41% of landlords reported being likely to sell properties during 2026, compared with just 19% in 2023-24. Rental supply remained approximately 22% below pre-pandemic levels in late 2025, even as demand moderated.
This supply-demand imbalance is the primary driver of the sustained rent growth seen since 2021, though the pace of increases has slowed markedly as tenant affordability has reached its limit and migration has fallen.
Current rental market conditions (2025-26)
According to Zoopla's Rental Market Report (March 2026), the average rent for new lets across the UK stood at £1,319 per month as of March 2026, having risen 1.9% in the previous year, down from 2.8% a year earlier. Demand for rental homes was 14% lower than a year ago, at its lowest level for six years, driven primarily by lower net migration. Supply, while still below pre-pandemic levels, has improved, and the market is becoming more balanced as a result.
Regional variation is significant. Some areas, particularly Northern cities and affordable commuter towns, continue to see above-average growth. Others, including some London boroughs and cities where supply has improved, have seen rents for new lets fall modestly.
From working with self-managing landlords across the UK, we observe that the landlords who are best positioned in the current market are those who have maintained their properties to a high standard and have invested in tenant relationships. In a market where tenants have more choice than they did two years ago, the ability to secure good tenants quickly and retain them at renewal is worth materially more than the ability to push rents to the ceiling at every review.
What the rental market means for landlords
For a landlord, understanding the rental market in their specific area is essential for three practical decisions: setting rent at the right level, assessing whether a potential investment will yield adequate return, and anticipating how market conditions affect demand and void periods.
Rent levels in the local market are the primary determinant of the achievable rent for any given property. A rent set significantly above comparable properties will extend voids; a rent set materially below comparable properties may attract tenants but erodes yield unnecessarily. For landlords assessing whether a local market justifies investment, rental yield is the primary metric. The annual rent expressed as a percentage of property value, net of running costs.
Landlords using August's property insights feature can see their own portfolio performance, including actual rent levels and void rates, against the wider market context, making investment and pricing decisions data-led rather than instinct-led.

The Renters' Rights Act and the rental market
The Renters' Rights Act 2025, in force from 1 May 2026, represents the most significant regulatory change to the rental market in a generation. Its most immediate market effects are structural: the abolition of Section 21 no-fault evictions removes the ability of landlords to exit tenancies without a valid ground, which has contributed to accelerated portfolio sales ahead of the Act's commencement. Rent increases are restricted to once per year and must follow a formal Section 13 notice procedure, removing the ability of landlords to use informal increases or contractual review clauses to adjust to market conditions between tenancies.
These changes do not reduce the rental market's fundamental supply-demand dynamic. The structural shortfall in housing supply relative to demand remains, and the Renters' Rights Act does not directly increase the number of homes available to rent. What it does is rebalance the market — tenants gain greater security and protection; landlords operate with greater regulatory obligations and reduced flexibility. For landlords who remain in the market and manage their properties professionally, the longer tenure security the Act promotes can be operationally beneficial, reducing turnover costs and void periods.

Frequently asked questions
What is the UK rental market?
The UK rental market refers to the system through which residential properties are let by private landlords and housing associations to tenants in exchange for rent. The private rental market, the private rented sector, accounts for approximately 4.7 million households (19% of all households in England) and is the second largest housing tenure after owner occupation. Rent levels within the market are determined by the local balance of supply (available homes) and demand (households seeking rental accommodation), subject to the legal framework that governs the landlord-tenant relationship.
Why are rents in the UK rental market so high?
UK rents have risen substantially since 2021 due to a combination of constrained supply and sustained demand. Supply has been reduced as many landlords have exited the sector in response to mortgage cost increases, tax changes including Section 24, and rising regulatory obligations. Demand has remained structurally high due to homeownership affordability barriers and household formation. According to Zoopla's March 2026 rental market report, UK average rents for new lets rose 1.9% in the year to March 2026, a significant slowdown from the 2022-23 peak, as tenant affordability limits and lower migration began to ease demand pressure.
How do I find the market rent for my property?
Market rent for a specific property is determined by comparing it against recently let comparable properties in the same area, similar size, type, condition, and location. Property portal data from Rightmove, Zoopla, and OnTheMarket provides asking-rent benchmarks. Local letting agents will typically provide a valuation based on achieved rents, which is a more reliable basis than asking rents alone. Factors that affect market rent above or below the local average include proximity to transport, the quality of the property, outdoor space, and whether utilities or furnishings are included.
