Rent Growth Slows to 3.4% as Renters' Rights Bill Nerves Ease

New rental market data shows annual rent growth across the UK has cooled to around 3.4%, down sharply from the double-digit peaks of 8-9% recorded in 2023, even as the Renters' Rights Bill edges closer to Royal Assent. This is a striking reversal of the narrative that has dominated landlord forums and property investment seminars for the past two years: that abolishing Section 21 "no-fault" evictions and moving all tenancies to a periodic basis would prompt landlords to either exit the market en masse or push rents higher to compensate for perceived new risks. The data suggests neither has happened at scale, at least not yet.

For UK property investors, this matters enormously because rental yield assumptions underpin almost every buy-to-let purchase decision, refinancing model and portfolio valuation in the country. A market where rent growth is decelerating rather than accelerating changes the calculus for landlords weighing up whether to expand, hold, or divest. It also undercuts the more alarmist commentary that has circulated since the Bill's second reading, which warned of a supply-driven rent spiral as nervous landlords quit the sector. Cooling rental inflation, set against a backdrop of continued build-to-rent expansion and a slow but steady recovery in mortgage approvals, points to a market rebalancing rather than one in crisis.

Regionally, the picture is far from uniform. London rents, having led the post-pandemic surge, are now growing at closer to 2.5% annually as affordability ceilings bite, particularly in zones 1 and 2 where average rents exceed £2,100 a month. Manchester and Leeds, by contrast, continue to see stronger growth of 4-5%, reflecting sustained inward migration, university demand and comparatively constrained new supply relative to population growth. Birmingham sits in the middle, buoyed by regeneration around the HS2 corridor despite the project's troubled recent history. Liverpool and Newcastle remain the standout yield markets for landlords, with gross yields still comfortably above 7% in some postcodes, even as rent growth there has also softened from last year's highs. Surrey and the wider commuter belt tell a different story again, with rent growth flattening as hybrid working reduces the premium tenants will pay for proximity to London termini.

The Renters' Rights Bill itself remains a significant structural change, and it would be wrong to suggest landlords have nothing to plan for. The abolition of Section 21, the introduction of a single system of periodic tenancies, and new grounds for possession tied to rent arrears and landlord circumstances will require portfolio landlords in particular to tighten tenant referencing and rent-arrears management. What the current data indicates is that the market has largely priced this in already, rather than reacting with a fresh wave of rent increases or panic selling. Anecdotal evidence from letting agents in Manchester and Birmingham suggests some landlords accelerated planned rent rises earlier in 2024 and 2025 in anticipation of the reforms, which may partly explain why growth is now cooling from an already-adjusted base.

Looking ahead six to twelve months, expect rental growth to continue moderating towards the 2-3% range nationally as affordability constraints, a modest uptick in rental supply from build-to-rent completions, and stabilising mortgage rates combine to take heat out of the market. First-time buyers should benefit indirectly: slower rent growth reduces the urgency to buy at any cost, giving prospective purchasers more room to save deposits and negotiate. Buy-to-let landlords with well-managed, compliant portfolios in strong regional cities are likely to see steady if unspectacular income growth, while highly leveraged landlords in marginal locations may find the maths increasingly unforgiving once the Bill's compliance costs are factored in alongside subdued rent growth. Commercial investors eyeing the private rented sector, meanwhile, should read this as validation of the institutional build-to-rent model, which is structured around stable, professionally managed income rather than opportunistic rent maximisation.

The clearest conclusion is that fears of a Renters' Rights-driven rent shock have proved overstated, at least in the data available so far. The legislation will reshape landlord behaviour and tenant protections meaningfully once implemented, but it has not been the catalyst for runaway rents that some in the industry predicted. Investors should treat the current cooling as evidence of a maturing rental market rather than a temporary lull before renewed inflation, and position portfolios accordingly around cities — Manchester, Leeds, Liverpool — where fundamentals remain strongest, rather than betting on legislative disruption to drive returns.
