Rent Bidding Ban Backfires: Landlords Now Price in the Premium Upfront

The Renters' Rights Act's ban on competitive rent bidding was designed to protect tenants from being priced out by desperate over-offers in a supply-starved market. Instead, new figures from Chestertons show landlords are simply building that premium into the asking price from day one. Rightmove data confirms the effect at a national level: asking rents rose 2.9% year-on-year in the second quarter of 2026, the strongest pace of growth in two years and a clear signal that regulatory intervention has redistributed pricing power rather than eliminated it.

This matters enormously for anyone with capital exposed to the UK private rented sector. The bidding ban was one of the flagship tenant protections in the Renters' Rights Act, alongside the abolition of Section 21 no-fault evictions and tighter restrictions on rent review clauses. Ministers framed it as a mechanism to stop landlords and agents exploiting desperate tenants during viewings, where multiple applicants were sometimes invited to outbid one another verbally on the day. What the legislation did not anticipate — or perhaps did not want to acknowledge — is that in a market where demand for rental stock outstrips supply by a wide margin, landlords retain enormous latitude to set the opening price wherever they judge the market will bear it. The bidding war has not disappeared; it has simply moved earlier in the process and been baked into the headline figure.

Regional variation illustrates how unevenly this repricing is landing. In London, where the rental market remains structurally undersupplied relative to jobs growth, average asking rents have pushed past £2,150 a month, up roughly 3.4% year-on-year. Manchester, long the poster child for institutional build-to-rent investment, has seen average rents climb to around £1,340, a 4.1% annual increase, as population growth continues to outstrip new completions. Liverpool has recorded one of the sharpest moves, up 4.5% to roughly £950 a month, reflecting intense investor and student demand chasing a comparatively small stock of professionally managed units. Birmingham (£1,210, up 3.8%), Leeds (£1,150, up 3.2%) and Newcastle (£890, up 3.9%) all show similar dynamics, while Surrey's more affluent commuter-belt market has grown more modestly at 2.7%, reaching around £1,650, reflecting a slightly better balance between family housing supply and demand.

Looking ahead six to twelve months, expect this front-loading of rent increases to intensify rather than fade. Landlords facing higher borrowing costs, mounting compliance burdens from EPC C minimum energy standards, and the removal of Section 21 as an exit route are recalibrating their entire risk model around the point of letting rather than mid-tenancy negotiation. With rent reviews during a tenancy now more tightly regulated, agents are advising landlords to set an ambitious opening rent because it is effectively their only unconstrained pricing opportunity for the duration of that let. Chestertons' data suggests this behavioural shift is already widespread among professional landlords and agencies, and it is likely to become standard market practice across the buy-to-let sector within the next two to three lettings cycles, particularly as smaller landlords take their cues from larger portfolio operators.

The consequences diverge sharply across market participants. Existing buy-to-let landlords who weather the current regulatory and tax environment stand to benefit from improved gross yields, even as capital values in some regions stagnate under mortgage rate pressure and tighter lending criteria. First-time buyers, however, face a genuine squeeze: higher rents erode the disposable income needed to build a deposit, extending the average time to purchase and pushing more would-be owners into prolonged renting, which in turn sustains rental demand and prices. Commercial investors and developers active in build-to-rent are arguably the biggest beneficiaries of this shift — institutional operators in Manchester, Birmingham and Leeds can absorb regulatory compliance costs at scale and are now able to set higher day-one rents with less reputational risk than smaller landlords navigating tenant relationships directly. Expect continued acceleration of institutional capital into purpose-built rental schemes in these cities over the coming year.

The lesson for the market is unambiguous: legislation aimed at curbing visible bidding wars has not addressed the underlying supply-demand imbalance driving rent inflation, and pricing power has simply relocated to the point of listing. Investors should treat the 2.9% headline rent growth not as a one-off adjustment but as the opening phase of a structural repricing across the private rented sector, with London, Manchester and Liverpool leading the trend and more moderate but persistent increases following across Birmingham, Leeds, Newcastle and the Surrey commuter belt. Policymakers hoping the Renters' Rights Act would meaningfully soften rent growth will need to confront the reality that regulating the mechanism of price discovery does little to change its ultimate outcome when rental supply remains this constrained.
