A stalling sales market, a moving rental pipeline

UK house price growth flatlined in the year to March 2026, with the average property holding at £268,000 according to the ONS/Land Registry UK House Price Index — the weakest annual reading since April 2024. England fared worse still, down 0.6% to £290,000, and London recorded its eighth consecutive month of annual price falls, dropping between 2.1% and 3.7% depending on the month sampled. Zoopla and Propertymark both point to Budget-driven uncertainty over housing taxation and higher mortgage rates as the drag, with buyers "negotiating more carefully" and sellers having to price realistically to attract interest.

Against that backdrop, capital earmarked for UK residential is increasingly bypassing the sales market altogether. Build-to-rent (BTR) and purpose-built student accommodation (PBSA) are absorbing a growing share of institutional attention, not because returns are guaranteed, but because the income profile is less exposed to capital value volatility and the planning pipeline for rented product is, on current evidence, moving faster than traditional housing.

Watkin Jones' recent run of deals is a useful bellwether. Its joint venture with Housing Growth Partnership delivered the 397-bed Venti House PBSA scheme in Stratford, aimed at the roughly 14,000 students studying near UCL East and the London College of Fashion. The group has since progressed a 484-bed scheme in Bristol's Temple Quarter, a 201-bed Bristol project, and the 784-bed "The Ard" scheme in Glasgow through a joint venture with Maslow Capital — while its FY2025 results showed BTR and PBSA revenue both falling sharply as the wider development market cooled. That combination — deal volume holding up structurally while headline revenue and profit compress — is itself a signal of where developer conviction now sits.

Why the planning pipeline favours rented product

REalyse planning pipeline data across the past three years shows a consistent pattern: BTR and PBSA schemes are being approved at meaningfully higher rates than traditional residential applications of comparable scale.

Across all three years, traditional residential schemes have been refused at roughly double the rate of BTR and PBSA applications, even though traditional schemes still account for the overwhelming majority of total submissions and units. Early 2026 figures point to a broader planning slowdown across the board — traditional residential approval rates have dipped toward the high 50s — but the relative gap in favour of rented-sector schemes has held.

This isn't necessarily about planning committees favouring BTR or PBSA in principle. It more likely reflects self-selection: institutional sponsors bring forward schemes on sites with stronger planning fundamentals, engage more consistently with local authorities pre-application, and can absorb longer gestation periods that speculative housebuilders often can't. Watkin Jones' description of its own pipeline — sites "secured" subject to planning, run alongside a live forward-funding book of roughly £2bn — reflects that patience. The Stratford scheme, incidentally, took from a 2024 joint-venture announcement through to practical completion for the 2026/27 academic year, a multi-year runway that only capital structured for long income can readily fund.

The yield and comparables case for pivoting

For lenders and investors underwriting today, the appeal isn't just about faster consent. It's about relative resilience of income. Where sales-led schemes are directly exposed to a flat-to-falling capital values environment — REalyse comparables data shows sold price per square foot largely tracking sideways across most English regions outside the East Midlands and East of England — BTR and PBSA income streams are underpinned by structural undersupply rather than owner-occupier sentiment.

Student accommodation in particular benefits from demand that is largely decoupled from mortgage rates and consumer confidence. Watkin Jones cites roughly 14,000 students within reach of its Stratford scheme alone, and REalyse-tracked PBSA pipeline data suggests several East London boroughs — Tower Hamlets, Newham, Hackney — have a backlog of consented but unfunded schemes, stalled less by planning risk than by the availability of forward-funding capital. That's precisely the gap joint ventures like Watkin Jones–HGP and Watkin Jones–Maslow Capital are designed to close: pairing sites that already carry planning momentum with balance sheets that can move at pace.

Gross-to-net yield comparisons continue to favour this thesis. Rental growth has stayed firmly positive even as sales values stall — ONS data shows UK private rents up 3.5% year-on-year to April 2026, with regional rental inflation as high as 6.5-7.6% in areas like the North East, comfortably outpacing both house price growth and general inflation. For institutions underwriting 10-15 year hold periods, an asset class where rental income is growing at multiples of capital value is a straightforward argument, even before accounting for the planning advantage.

Outlook

None of this suggests BTR and PBSA are immune from the broader slowdown — Watkin Jones' own FY2025 numbers, with BTR revenue down 14.2% and PBSA revenue down 42.4%, show that deal volume and delivered revenue can diverge sharply when funding conditions tighten. But the direction of travel in planning consents, rental growth and institutional deal structuring all point the same way.

For developers and lenders watching the pipeline, the metric worth tracking isn't headline deal announcements — it's the conversion rate of already-consented BTR and PBSA sites into funded starts. If that conversion accelerates through the rest of 2026, it will confirm that the shift toward rented product is structural rather than a temporary hedge against a flat sales market.
