The stay-at-home shift is redrawing UK student accommodation demand

A structural shift in student housing demand

For years, the UK purpose-built student accommodation (PBSA) investment case rested on a simple, durable premise: a growing, internationally diversified student population chasing a stubbornly undersupplied stock of beds. That premise still holds in aggregate terms, but the composition of demand underneath it is changing in ways that institutional investors, lenders and developers can no longer treat as noise.

UCAS figures for the 2026 admissions cycle show 38% of UK acceptances indicated an intention to live at home while studying, up from roughly 32% in 2017 — a rise of more than six percentage points in under a decade, and the figure has climbed every year since 2022. Among UK 18-year-olds specifically, the intention-to-live-at-home rate is now above 44%, with over 750,000 applicants nationally flagging a preference to commute rather than relocate. In Scotland and Northern Ireland, where tuition and transport economics differ from England, first-year commuter rates are already running at a third or more of intake.

This is not a temporary post-pandemic blip. It is the cumulative effect of maintenance loan values failing to track rent inflation, average PBSA rents pushing into the £180–£270 per week range in high-demand cities, and universities actively redesigning timetables and campus facilities — commuter lounges, condensed teaching days, off-peak gym access — to accommodate a cohort that no longer defaults to halls.

What this means for PBSA occupancy and rental growth

The sector's recent trading updates already hint at where this is heading. National PBSA booking rates for the 2026/27 cycle were tracking meaningfully behind prior years as of mid-2026, and private-sector occupancy across the cycle has been estimated at around 85%, down from a pre-pandemic norm closer to 95–98%. Glasgow and Edinburgh — two markets that expanded PBSA supply aggressively over the past decade — have seen some of the sharpest occupancy declines, with Glasgow's booking rate for 2026/27 reported at roughly half the level seen at the same point two years earlier.

It would be wrong to treat this purely as a supply-side story. Structural undersupply is real — Savills puts the UK student-to-bed ratio at around 2.7–3.0 full-time students per purpose-built bed across the twenty largest markets, with an estimated 200,000-plus beds still needed to reach healthier provision levels. But undersupply and softening occupancy can coexist when the pool of students willing to pay for a bed is itself shrinking at the margin. REalyse data on rental listings and achieved rents across major university postcodes can isolate this effect at a local level, comparing asking-to-achieved discount trends and days-to-let for PBSA-adjacent postcodes against the wider market, rather than relying on national averages that can mask city-by-city divergence.

For underwriters, the practical implication is that the "safe" assumption of near-full occupancy as a backstop to rental growth assumptions needs re-testing market by market. A scheme in a city with a large commuter catchment — somewhere like Bradford, Sunderland or outer-London boroughs with strong rail and road links to a major campus — may carry materially higher leasing risk than the same unit economics would suggest in a city where the university draws predominantly from outside commuting distance, such as St Andrews or Durham.

Affordability pressure is reshaping where demand concentrates

The commuter shift is fundamentally an affordability story, and it is landing unevenly across the market. Unite, the UK's largest listed PBSA operator, has flagged that rents would need to reach roughly £12,000–£13,000 a year in most markets to make new development viable against current build costs, against an achieved UK average closer to £8,000. That gap is precisely the territory where commuter substitution bites hardest: students priced out of newer, amenity-rich studios are either opting to live at home or trading down into HMOs and shared houses rather than leaving the market altogether.

This has two consequences worth separating. First, demand is polarising by institution tariff. UCAS data shows higher-tariff providers capturing a growing share of total acceptances — over 40% in 2026, up more than 1.5 points year-on-year — while lower-tariff institutions lost share. Russell Group and other high-tariff universities, which draw more heavily from outside their immediate city and retain stronger international cohorts, are proving more resilient to the commuter trend than post-92 institutions with large local catchments, where day-one intention-to-live-at-home rates can be considerably higher than the national average.

Second, the squeeze is reviving appetite for traditional student HMOs in markets where PBSA has become too expensive relative to local incomes and loan support. REalyse's HMO licensing and comparables data can help investors and lenders identify postcodes near universities where licensed HMO stock is thinning — often due to Article 4 restrictions or landlord exits linked to tax and regulatory changes — even as local commuter and budget-conscious demand persists. Those markets may offer a more defensible income case than a new-build PBSA scheme chasing rents the local catchment cannot sustain.

Implications for underwriting and development appraisal

For institutional investors and lenders, three adjustments to standard PBSA underwriting practice look increasingly warranted:

• Catchment-adjusted demand modelling. Rather than applying a flat city-level student-to-bed ratio, appraisals should weight for the share of a university's intake likely to commute, using institution-level UCAS data alongside transport accessibility analysis. A scheme adjacent to a university with a high commuter share needs a materially different occupancy sensitivity than one serving a predominantly residential cohort.

• Rent-to-loan coverage as a leading indicator. With maximum maintenance loan support in England sitting below the annual rent on a typical en-suite PBSA room in many cities, tracking the gap between loan coverage and achieved rent by postcode — something REalyse's rental comparables data supports — offers an early warning signal for leasing risk that is more forward-looking than trailing occupancy figures.

• Diversified exit and operator strength. Given softening national occupancy and muted rental growth (around 2% in 2025/26 versus the 7%-plus seen a few cycles earlier), scheme valuations should place more weight on operator covenant and nomination agreement coverage, and less on extrapolating historical rental growth trajectories.

Development strategy is adjusting in parallel. Several large operators have already signalled they will concentrate new delivery on a smaller number of high-tariff, high-retention university markets rather than pursuing broad-based regional expansion — a rational response to a demand pool that is bifurcating rather than growing uniformly.

Outlook

None of this points to a collapse in the PBSA investment case. The sector remains structurally undersupplied against total student numbers, investment volumes into operational assets have held up, and well-located schemes serving universities with resilient residential catchments should continue to command premium rents and strong occupancy. But the stay-at-home shift means the sector's growth is becoming more selective rather than broad-based.

For developers, lenders and investors, the practical takeaway is to stop underwriting PBSA as a single national asset class and start pricing it as a portfolio of distinct local markets, each shaped by its own mix of institution tariff, commuter accessibility and loan-to-rent affordability. Tools that combine granular rental comparables, HMO licensing data and planning pipeline visibility at postcode level — rather than city-wide averages — are becoming essential to telling those markets apart before capital is committed.
