A pipeline running dry

England's housebuilding pipeline is being squeezed at its source. Government planning statistics show residential permissions falling to their lowest levels since the late 1970s, a downturn that has been building steadily since the mid-2020s rather than arriving as a single shock. For developers, lenders and investors underwriting delivery against 2026 targets, the numbers raise an uncomfortable question: if fewer schemes are getting consent today, where does next year's supply come from?

REalyse planning pipeline data illustrates the scale of the drop. Granted residential applications across England have fallen from roughly 28,500 in 2018 to around 11,500 in 2024, with associated approved unit volumes down from over 449,000 to roughly 216,000 over the same period — a decline of more than half in unit terms in just six years. Early-year 2025 figures point to further contraction, continuing a run of consecutive annual declines that has not been seen in the modern planning system.

Why approvals are drying up

The causes are structural as much as cyclical. Local authority planning departments have faced sustained resourcing pressure, slowing case processing and pushing more applications into extended negotiation or refusal. Nutrient neutrality restrictions, biodiversity net gain requirements, and stricter build-safety and fire-safety sign-off have added new pre-consent hurdles in many districts, particularly across the South East, East Anglia and parts of the North West.

Viability has compounded the effect. With build costs still elevated relative to pre-2022 levels and higher debt costs squeezing scheme economics, fewer sites are being brought forward for submission in the first place — meaning the fall in approvals partly reflects an even sharper fall in applications. REalyse data across comparable local authorities shows this viability gap most acute for flatted schemes in urban regeneration areas, where gross development values have not kept pace with build cost inflation, discouraging both submissions and approvals of higher-density consents.

Local plan coverage remains a further constraint. A material share of local authorities are still working from local plans adopted several years ago or are without an up-to-date five-year land supply position, leaving planning committees more exposed to speculative appeals but also, in practice, more cautious about greenfield and edge-of-settlement approvals.

What it means for 2026 targets and land supply

The implication for England's housebuilding ambitions is direct: planning permissions are typically the leading indicator for completions 18–36 months out, and the current trajectory does not support the delivery run-rate needed to hit stated 2026 housebuilding ambitions. Developers with land banks secured under earlier, more permissive planning cycles are relatively insulated in the near term, but those relying on fresh consents to replenish pipeline face a widening gap between target output and deliverable supply.

For land supply specifically, falling approval volumes tighten the pool of "oven-ready" sites just as demand for shovel-ready land from housebuilders and build-to-rent investors remains firm. REalyse comparables across local authority areas show consented land increasingly commanding a premium over unconsented sites, reflecting the option value of a live permission in a slower-approval environment. Investors and lenders underwriting land-led transactions should treat planning risk — not just market risk — as a primary driver of scheme timelines and exit assumptions.

Regional variation matters here too. Local authorities with adopted, up-to-date local plans and pro-growth planning committees are pulling further ahead on approval rates relative to areas still operating under outdated policy frameworks, widening the gap in investable pipeline between "planning-friendly" and "planning-constrained" markets. For portfolio-level strategy, tracking approval rates and average determination times by local authority is becoming as important as tracking price growth or rental yield.

Outlook

Absent a meaningful acceleration in local authority resourcing or planning reform delivery, the approvals slowdown looks set to persist into the medium term, keeping upward pressure on land values for consented sites and widening regional disparities in deliverable pipeline. Developers and investors are likely to place a growing premium on local authorities with clear plan coverage and faster determination times, while lenders assessing development finance will need sharper visibility on planning risk at the site and authority level. Monitoring granted units, not just headline transaction volumes, will be essential to gauging where England's housing supply is genuinely heading over the next two to three years.
