Three checks before using a Q3 planning headline in a development finance case: the denominator, unknown outcomes and the gap between regional evidence and a specific project.
A falling planning approval rate can survive a demanding sensitivity check and still tell you very little about the financeability of an individual project. Georgina explains three checks to make before using a Q3 headline in a development funding case.

The original ICPSR planning study, version 1 provides the approval-rate analysis and backing evidence. The Hugging Face planning unit-definition study addresses a separate question: how an inclusion filter changes the unit trend. Applications, approvals and dwellings are different measures.

Planning approvals fell. Does that change your development finance case?
Welcome to the Construction and Capital Podcast. I'm Georgina. Today's research briefing is written by Matt Lenzie, using Construction Capital's third-quarter twenty twenty-six planning evidence.
Imagine you are preparing a funding memo for a development. You find a regional report showing that the planning approval rate has fallen. It is tempting to turn that into a sentence about a tougher market, and then carry the same conclusion into your finance case.
Before you do, there are three questions worth asking. What went into the rate? Could the unknown outcomes change its direction? And what does the result actually tell you about your own scheme?
Start with the headline. In a matched panel of two hundred and fifty-three authorities, the approval rate fell from seventy-one point nine six per cent in the third quarter of twenty twenty-five, to sixty-eight point three eight per cent a year later. That is a decline of three point five eight percentage points.
This is a partial panel, not a complete national planning census. The same authorities are included in both periods. The calculation uses approvals divided by approvals plus refusals. Withdrawals are outside it. So are recorded decisions whose outcome has not been classified.
That last group matters. There were one hundred and ten recorded unknown outcomes in the earlier quarter, and one hundred and thirty-one in the later one.
Here is the second question. Could those unknowns overturn the headline?
We can test the most extreme assignments without pretending to know what happened to any individual application. Give every unknown in twenty twenty-six an approval, and every unknown in twenty twenty-five a refusal. That is the assignment most favourable to the later quarter.
The panel's approval rate still falls, by about two point three one percentage points. Reverse the assignments, and the decline becomes about four point nine one points.
The useful conclusion is quite precise. The unknown-outcome category, on its own, cannot reverse the panel's direction. That does not establish why the rate fell. It does not solve missing coverage or errors in the original records. And it is not a probability forecast.
Now look underneath the panel. Construction Capital's new interactive explorer applies the same test to seven custom regional groups. Six retain their direction under every possible assignment of their recorded unknowns. Five always fall, while the South West always rises.
The exception is the East of England. Its known-outcome comparison shows a fall of roughly half a percentage point. But the extreme assignments run from a decline of one point six four points to a rise of zero point seven seven points.
For that group, a firm claim that approvals deteriorated is more than the recorded outcomes can support. You can say the known-outcome rate fell, provided you also explain that assigning the unknowns differently can change the direction.
The distinction is useful in a funding memo. A large movement may survive a demanding check, while a small movement can depend on how a small missing category is treated. The same headline style should not be used for both.
That brings us to the third question. What does this mean for development finance?
A regional approval rate supplies background. It does not price a loan, measure lender appetite, or tell you the chance that your site gets permission. These aggregates do not identify which planning decisions led to financed projects.
Keep the market paragraph separate from the evidence about the scheme. In the market paragraph, state the geography, period, denominator and limitation. For the project itself, examine the actual consent position and outstanding conditions. Keep the cost plan, delivery assumptions and proposed funding structure explicit as separate matters.
If you are writing about the East of England, for example, a careful sentence would say that the known-outcome rate fell slightly, but the direction is sensitive to recorded unknowns. That is a hypothetical drafting example, not a description of a particular client's project.
There is another trap. An approval-rate test and a housing-unit test answer different questions. The companion planning study on Hugging Face examines how inclusion rules change the reported unit trend. You should not treat an approval, an application and a dwelling as interchangeable observations.
The show notes link to that study, the original planning report on I C P S R, and the interactive explorer. The explorer includes the source counts, a downloadable results table and code to reproduce the calculation. You can change the assignments yourself, one recorded outcome at a time.

Before your next funding memo, check the denominator, test the unknowns, and keep the market evidence separate from the project's own case. Thanks for listening.
