A widening gap between ambition and delivery

Housebuilders and developers are submitting more planning applications than they have in several years, buoyed by policy signals on housing targets and a modest recovery in land transactions. On paper, this looks like the start of a supply-side rebound that lenders, investors and local authorities have been waiting for.

But the number that matters most to anyone underwriting a scheme or forecasting completions is not applications submitted — it is applications granted, and, further downstream, homes actually built. Across much of England, Scotland and Wales, approval rates and build-out have not kept pace with the rise in submissions. That divergence is the real story, and it raises an uncomfortable question for the sector: is the pipeline genuinely improving, or is it simply inflating with schemes that will sit in limbo for years?

Applications up, approvals flat: reading the pipeline correctly

Planning pipeline data — tracked at project level with submission dates, decision dates, decision outcomes (granted, refused, in progress, withdrawn), unit counts and site values — gives a much sharper read than headline application volumes alone.

REalyse data shows that when we segment the pipeline by decision status rather than submission status, a large and growing share of "live" applications sit in prolonged "in progress" limbo, often for 12–24 months beyond typical local authority determination timeframes. Refusal rates in several high-demand local authorities have also crept up over recent cycles, particularly for larger schemes above 50 units, where affordable housing contributions, biodiversity net gain requirements and infrastructure capacity assessments introduce additional friction.

This matters commercially in a few distinct ways:

For developers and investors

A rising application count without a corresponding rise in grants inflates the apparent size of the "opportunity pipeline" without improving deliverable supply. Underwriting a site on the assumption that planning risk is falling — because more schemes are in the system — is a mistake if approval timelines and refusal risk in the relevant local authority haven't actually improved. Comparing planning-stage GDV assumptions against realistic approval probabilities, by local authority and unit scale, is now a critical due diligence step rather than a nice-to-have.

For lenders and credit teams

A backlog of undetermined or stalled applications is a leading indicator of construction finance risk. Loan books with concentrated exposure to local authorities carrying above-average "in progress" backlogs may be more exposed to delayed drawdowns and extended facility terms than the headline pipeline suggests. Screening exposure by local authority determination speed — not just by geography or asset type — offers a more accurate risk lens.

For agents and valuers

Where planning pipelines are large but approval-to-completion conversion is weak, forward-looking supply assumptions used in comparable-based valuations can overstate near-term stock increases. This has knock-on effects for pricing new-build premiums and for advising vendors and investors on likely competition from schemes that may never reach practical completion within a normal disposal timeframe.

Where the bottlenecks are concentrated

The gap between submissions and grants is not evenly spread. REalyse's planning pipeline analysis, cut by local authority, sector group and unit scale, points to a few consistent patterns worth flagging to institutional audiences:

• Larger schemes face disproportionate delay. Applications above roughly 50–100 units, particularly Build-to-Rent and mixed-tenure schemes, tend to carry longer "in progress" durations than smaller infill applications, reflecting the added complexity of viability negotiations and affordable housing quotas.

• High-demand urban local authorities show the widest application-to-grant gap. Areas with strong underlying housing need and land value pressure — many in London, the South East and parts of the core cities — often show the largest divergence between submission growth and grant rates, a sign that political and capacity constraints, not lack of developer appetite, are the binding constraint.

• Stalled schemes cluster geographically. Sites with planning consent but no recorded start on site for an extended period tend to concentrate in specific local authorities and site typologies (notably brownfield regeneration and land requiring significant remediation or infrastructure unlocking), rather than being randomly distributed — useful context for investors screening for "shovel-ready" versus "paper-ready" opportunities.

What this means for the housing supply narrative

None of this means the increase in applications is meaningless. Rising submissions do reflect genuine developer confidence and land activity, and a healthy pipeline has to start somewhere. But treating gross application volume as a proxy for future housing delivery risks overstating how quickly supply will respond, both for policymakers setting housing targets and for investors modelling absorption and rental supply growth in build-to-rent or single-family housing strategies.

The more useful lens — and the one institutional users increasingly apply — is a funnel view: applications submitted, applications granted, schemes started on site, and units completed, each benchmarked against local authority-level historical conversion rates. Where that funnel narrows sharply between submission and grant, or between grant and start-on-site, the pipeline is better read as a queue of intent rather than a forecast of delivery.

Outlook

Expect the application-approval gap to remain a defining feature of the UK development landscape over the next few cycles, particularly while local authority planning capacity, affordable housing viability negotiations and environmental assessment requirements continue to add time to determination processes. For developers, lenders and investors, the practical response is not to wait for policy fixes but to price planning risk more granularly — by local authority, scheme scale and sector — using conversion-rate evidence rather than headline application counts. Those who can distinguish a genuinely accelerating pipeline from one that is simply getting longer and more crowded will be better placed to underwrite, lend against and value sites with confidence.
