A surge in applications, but is it translating into homes?

UK planning application volumes have reportedly climbed back towards their highest levels in five years, as councils process a backlog shaped by shifting national policy, reintroduced housing targets, and developers moving early to beat incoming regulatory changes such as biodiversity net gain requirements and updated building safety rules. For an industry that has spent years blaming planning delay for the housing shortfall, that should be good news.

But for institutional investors, lenders and developers underwriting sites today, the more important question isn't how many applications are being submitted — it's how many of those consents actually turn into groundworks, drawdowns and completed units. REalyse's planning and development data lets us test that directly, tracking individual schemes from submission through decision to construction start. The picture that emerges is more cautious than the headline "planning revival" narrative suggests.

What REalyse data shows: a widening approval-to-delivery gap

Looking at residential planning applications with a recorded decision and construction start date, the conversion rate from granted units to units actually breaking ground held in a healthy 84–89% range through 2021–2023. From 2024 onward, that rate dropped materially — falling into the 64–71% range across 2024 and 2025, even as total granted units remained substantial year-on-year.

In practical terms: a meaningful and growing share of consented residential units are sitting un-started. That's consistent with what many developers and lenders have been reporting anecdotally — viability gaps driven by build cost inflation, tighter development finance, and, in some segments, softer sales absorption rates — but it's notable to see it show up so clearly in the scheme-level data rather than just in survey sentiment.

For lenders and credit analysts, this matters for two reasons. First, a granted consent is not itself a strong signal of delivery timing — modelling drawdown schedules purely off decision dates risks overstating near-term completions. Second, sites with stalled starts often carry embedded viability stress (land value, build cost, or exit price mismatches) that's worth flagging before it shows up as a covenant issue.

Regional variation matters

England accounts for the overwhelming majority of granted residential units nationally, but Scotland, Wales and Northern Ireland each show materially smaller and more volatile application volumes year to year — a reminder that "UK planning reform" doesn't move uniformly across the four nations. Local authority capacity, resourcing, and differing planning frameworks (particularly Scotland's separate system and Wales's distinct development plan process) mean the applications-to-starts gap is unlikely to close at the same pace everywhere. Investors comparing opportunities across nations should expect delivery timelines — not just consent probability — to diverge by geography.

Reform is necessary, but it isn't sufficient

The policy logic behind recent planning reform — mandatory housing targets, streamlined committee processes, presumption in favour of sustainable development — is aimed squarely at the consenting stage. If applications are indeed rising, that's evidence the reform agenda may be nudging more schemes into the system. But REalyse's data suggests the bottleneck has partly shifted downstream: from "can we get permission" to "can we make the numbers work to start on site."

That has direct implications for how professional investors and developers should be reading the current cycle:

• For developers and development managers: benchmarking a site's viability against REalyse comparables for build cost, achieved sale price per sq ft, and absorption rates is arguably more decision-critical right now than the planning risk itself.

• For lenders and credit analysts: tracking construction start rates by borrower, region and asset type — not just consent status — gives an earlier read on portfolio delivery risk.

• For investors: areas with rising consents but weak start rates may represent either a buying opportunity (land banked at depressed values, awaiting a viability turn) or a warning sign of a structurally stuck pipeline, depending on local demand fundamentals.

Outlook

The rise in planning applications is a genuinely useful leading indicator — but only if it's read alongside delivery data, not instead of it. Until build costs, finance conditions and sales absorption improve enough to close the gap between consent and construction start, a five-year high in applications risks becoming a five-year high in unbuilt permissions rather than new homes. Institutional players who track the full pipeline — from submission to start to sale — will be better placed to separate genuine delivery opportunities from paper pipeline.
