A pipeline built on a narrow base

Purpose-built student accommodation has been one of the UK's most resilient real estate sub-sectors over the past decade, underpinned by rising international enrolment, chronic undersupply in many city centres, and yields that have held up better than much of mainstream residential. But the shape of the current development pipeline suggests that resilience is increasingly concentrated rather than broad-based.

Industry pipeline tracking puts the share of new PBSA beds due to complete in 2026 that sit within Russell Group university markets at around 93%. That is an extraordinary degree of concentration for a sector that, on paper, serves well over 150 higher education institutions across England, Scotland, Wales and Northern Ireland. Russell Group cities — Manchester, Leeds, Bristol, Birmingham, Glasgow, Edinburgh and a handful of others — have become the default underwrite for institutional capital, on the logic that larger, more selective universities guarantee more durable tenant demand.

The problem is that this logic has, in places, stopped being tested against local-level data. When capital allocation follows university prestige rather than ground-level absorption rates, days-on-market trends and rent growth at the scheme level, the market risks building up concentration risk in exactly the locations where competition for sites and planning consents is already fiercest — while under-serving, or mispricing, demand in cities with genuine but less "investable" student populations.

Where the vacancy signal is flashing

Nottingham is the clearest current example of a city where the oversupply narrative is turning from theoretical to visible. Reported vacancy rates in parts of the city's PBSA stock have reached 12.7%, a level that would be unusual in a mainstream Build-to-Rent scheme and is materially above what operators typically underwrite for stabilised student assets, where vacancy of 2–5% is the more conventional planning assumption.

Nottingham is not a marginal university city — it hosts two large institutions and a substantial student population — which is precisely what makes the vacancy figure notable. It suggests that oversupply risk is not confined to cities with structurally weak higher education demand, but can also emerge in solid, well-established markets where development has simply outpaced genuine bed-for-bed need, or where new stock has been delivered in the wrong typology, price point or location relative to where students actually want to live.

REalyse planning and development data shows a similar pattern taking shape elsewhere: several non-Russell Group cities with meaningful student populations have seen clusters of PBSA planning consents move through in relatively short succession, often from multiple operators targeting the same catchment with limited visibility of each other's pipelines. Where several hundred beds are delivered into a market within an 18–24 month window, without a corresponding increase in overall student numbers, rental growth and achieved occupancy are the first indicators to soften — typically well before vacancy becomes visible in headline reporting.

Are developers and lenders pricing the right risk?

The central question for institutional capital is whether underwriting models have kept pace with this shift. Much PBSA appraisal still leans on university reputation and historic occupancy as a proxy for forward demand, rather than granular, scheme-level comparables of asking rent, achieved rent, void periods and rent-to-income affordability in the specific micro-market being developed.

That approach made sense when PBSA supply was genuinely scarce almost everywhere. It is less reliable now that supply has become lumpy and city-specific. A lender assessing a new scheme in a secondary city needs more than the university's Russell Group status (or lack of it) — they need visibility of:

• The existing and pipeline PBSA bed count within walking distance of campus, including consented but not-yet-built schemes that competitors may be sitting on

• Achieved rent and occupancy trends on comparable existing stock, not just asking rents on new-build marketing material

• Local rental affordability relative to typical student and parental income, since asking rents in some secondary cities have risen faster than wage growth in the surrounding working population

• Local authority planning policy and any Article 4 Direction activity around HMO conversion, which affects the private rented alternative that students can fall back on if PBSA pricing is too aggressive

Where this analysis is skipped, the risk is a familiar one from past real estate cycles: capital continues to chase a small number of "safe" locations even as yields compress there, while genuine opportunities — and emerging risks — in a wider set of cities go underpriced in both directions. Some secondary markets may in fact be undersupplied and offer attractive risk-adjusted entry points; others, like parts of Nottingham's current stock, may already be showing the early signs of oversupply that warrant caution on new consents rather than continued delivery.

What this means for the next development cycle

For developers, the practical implication is that site selection needs a harder look at bed-to-student ratios and the existing competitive pipeline, not just a city's position in the university prestige hierarchy. A smaller, well-researched scheme in an under-supplied secondary city may carry a more attractive risk-return profile than a seventh competing tower in a Russell Group city centre.

For lenders, the Nottingham example is a useful stress test. Loan books with concentrated exposure to a handful of Russell Group markets may feel protected by name recognition, but uniform geographic concentration is itself a risk factor if those markets are also where yield compression and rising construction costs are squeezing development margins hardest. Equally, exposure to secondary cities should be assessed scheme-by-scheme against local absorption data rather than treated as uniformly higher risk.

As the 2026/27 academic year approaches, the PBSA sector's next phase of performance is likely to be defined less by the headline Russell Group versus non-Russell Group divide, and more by which operators and lenders did the granular, local-market homework before committing capital. Markets that look similar on a university league table can behave very differently once pipeline, pricing and real occupancy data are compared side by side.
