A growing pipeline, a shrinking gate

England's housebuilding pipeline is busier than it has been in years. REalyse planning data shows residential applications submitted nationally climbed sharply from 2021 into 2022, and while volumes have since cooled from that peak, they remain well above pre-2022 levels — with 2025 applications running close to double the 2021 total.

The problem isn't a shortage of proposals. It's what happens to them next. Approval rates — the share of granted schemes among those actually decided — have drifted downward from around 73–74% in 2021–2022 to roughly 69–70% through 2023–2025. That's not a collapse, but it is a persistent, multi-year erosion at exactly the moment the sector needs more homes moving through the system, not fewer.

For developers, investors and lenders underwriting sites on the assumption of "likely consent," that erosion matters. A few percentage points of approval-rate decline, applied across tens of thousands of applications, translates into thousands of homes stuck in limbo each year — schemes that have absorbed pre-application costs, viability work and community consultation, only to stall at committee.

Where the bottleneck really sits

The national picture masks enormous local variation, and this is where REalyse's local authority-level comparables become essential for site selection and risk pricing. Among the local authorities generating the highest volumes of residential applications, approval rates range from below 45% to nearly 80% — a gap wide enough to make or break a scheme's viability case before a single brick is laid.

London boroughs feature heavily among both the busiest and the most conservative authorities. Areas such as Croydon and Brent show approval rates materially below the national average, sitting closer to the 40–55% range, while high-volume authorities outside London — including parts of the South West and North Yorkshire — are approving closer to 80% of decided applications. Birmingham, despite strong application volumes, also sits below the national average on approval rate.

This isn't simply a London-versus-the-rest story. It points to genuine local authority capacity constraints, differing appetite for density and design compromise, and inconsistent application of the National Planning Policy Framework at committee level. For institutional investors comparing sites across regions, local approval-rate benchmarking is no longer optional due diligence — it's a pricing input.

What's driving the disconnect

A few structural factors help explain why more applications aren't converting into consents:

• Planning department capacity — many local planning authorities have seen resourcing pressure and staff turnover, extending decision timescales and pushing more applications toward committee-level scrutiny rather than delegated officer sign-off, where refusal risk tends to be higher.

• Rising withdrawal and pending volumes — REalyse data shows the pool of withdrawn or still-undecided applications has grown alongside submission volumes, suggesting schemes are increasingly being pulled or renegotiated pre-decision rather than refused outright, which still delays delivery even where it doesn't show up as a formal refusal.

• Viability tension — with build costs and finance costs elevated relative to a few years ago, more schemes are being submitted at unit mixes or densities that push against local plan policy on affordable housing and design, increasing the chance of refusal or costly amendment cycles.

• Political and local scrutiny — councillor-level decisions, particularly in areas with vocal local opposition, continue to diverge from officer recommendations more often in higher-density, higher-profile schemes — a pattern visible in the lower approval rates concentrated in specific London boroughs and major cities.

What this means for underwriting and site selection

For lenders and investors, the message from this data is straightforward: a rising national application count is not, on its own, a leading indicator of future housing delivery. The conversion rate from application to consent — and the time it takes to get there — is the more reliable signal, and it varies enormously by local authority.

REalyse's planning and development data allows users to benchmark a target site's local authority against its approval-rate history, decision timescales and unit-mix precedent before committing capital to site acquisition or pre-application work. Combined with comparables on achieved sale prices and rental yields in the same postcode district, this gives a fuller picture of whether a scheme is likely to clear the planning gate on the timescale and unit mix assumed in the business plan.

Outlook

Unless local planning authority resourcing and committee-level consistency improve, the gap between rising application volumes and stagnant approval rates looks set to persist into 2026. For developers and investors, that argues for treating planning risk as a distinct, locally-priced variable — not a national assumption — when screening sites and stress-testing development appraisals.
