Planning Applications by the Numbers: A 2026 Snapshot

Published 16 March 2026

Planning Signal tracks over half a million planning applications across 380+ UK councils. That dataset tells a story about what people actually build, how the system works in practice, and where the pressure points are. Here is what the numbers reveal about the state of planning in the UK right now.

The Big Numbers

549,000+ total planning applications tracked
380+ councils monitored daily
25,000+ registered architects in our directory
236,000+ registered contractors
43,000+ towns and villages with data

These figures represent a comprehensive snapshot of the UK planning system. Every day, new applications appear on council planning portals, and every day, decisions are made that shape neighbourhoods, affect property values, and determine what gets built.

What Are People Applying For?

Not all planning applications are for house extensions. The full breakdown of application types challenges some common assumptions about what the planning system actually handles:

Full applications - 231,392 (42% of all applications)
Discharge of conditions - 68,624 (12%)
Tree work - 62,127 (11%)
Outline applications - 59,587 (11%)
Amendments (non-material/minor) - 28,080 (5%)
Heritage/listed building - 25,814 (5%)
Householder - 13,059 (2%)
Advertising/signage - 11,592 (2%)

The first thing most people notice is that householder applications, the category that covers home extensions and loft conversions, account for only 2% of the total. This is misleading. Many householder projects fall under permitted development and never appear on planning portals at all. The extensions you see being built on your street may never have needed a planning application.

Full Applications Dominate

At 42%, full planning applications are the system's workhorse category. This covers everything from a single new dwelling in someone's garden to a 500-home housing estate, from a change of use (converting a shop to a restaurant, or a house to flats) to a new industrial unit. The breadth of this category is staggering, and it explains why processing times vary so dramatically. A full application for a garden shed that exceeds permitted development limits and a full application for a 20-storey mixed-use tower both sit in the same statistical bucket.

Tree Work Is Bigger Than You Think

One in nine planning applications is about trees. That is 62,127 applications for pruning, felling, or works to trees in conservation areas and those covered by Tree Preservation Orders. If you have a protected tree in your garden, you need the council's written consent before you pick up a chainsaw. Even dead wood removal on a TPO tree technically requires notification.

The volume of tree applications creates a genuine administrative burden. Each one requires assessment by a tree officer or arboriculturist, and many councils have only one or two dedicated tree officers handling thousands of applications per year. This explains why tree application decisions can take longer than the statutory period, despite being relatively straightforward assessments.

Conditions Dominate Post-Approval Work

The second-largest category is not a new application type at all. It is discharging conditions attached to existing approvals. Nearly every planning permission comes with conditions: approved materials, landscaping schemes, drainage strategies, construction management plans, hours of construction, boundary treatments. Each condition needs a formal application to discharge it before or during the build.

A typical housing development might have 20-30 conditions attached to its permission. That means a single approved scheme generates dozens of follow-up applications, each requiring officer time and a formal decision. For developers, managing condition discharge is a significant project management task. Miss a pre-commencement condition and you risk invalidating your entire permission.

Outline Applications: Testing the Water

Despite the extra step involved (you still need "reserved matters" approval before you can build), outline applications account for 11% of all submissions. They establish the principle of development without committing to detailed design. This makes them popular in several scenarios.

Land sellers use them to establish planning potential before marketing a site. A field with outline permission for five houses is worth considerably more than a field without any planning status. Developers use them to test whether a council will accept development on a site before spending money on detailed architectural drawings. And homeowners occasionally use them to establish whether building in their garden is acceptable in principle.

Heritage: A System Within a System

Heritage applications (listed building consent, conservation area works, and applications affecting heritage settings) account for 5% of all cases. That might sound small, but these applications consume disproportionate officer time. They require specialist knowledge, consultation with Historic England for significant cases, and detailed heritage impact assessments. A single listed building consent application for internal alterations to a Grade I property might take longer to assess than a dozen straightforward householder extensions.

The Advertising Surprise

Over 11,500 applications relate to advertising and signage. Every illuminated shop sign, billboard, estate agent board (in certain areas), and banner needs advertisement consent. Businesses opening new premises often forget this requirement entirely, putting up signage without permission and risking enforcement action. The rules are particularly strict in conservation areas, where even the colour and font of a shop sign can be controlled.

What the Regional Split Reveals

Application volumes are not evenly distributed. London boroughs handle high volumes of householder and change-of-use applications in small geographic areas. Rural authorities handle fewer applications but over vast territories, meaning site visits take longer and local knowledge is harder to maintain. Coastal authorities deal with flood risk on almost every application. Former industrial areas see clusters of contaminated land assessments.

The planning system is not one system. It is 380+ local systems, each shaped by geography, politics, staffing levels, and local priorities. A planning application in Westminster operates in a completely different context from one in the Scottish Highlands, even though both follow broadly similar legislation.

Processing Times: The Hidden Story

The government sets targets of 8 weeks for minor and householder applications, and 13 weeks for major developments. In practice, many councils routinely exceed these targets, particularly for complex applications. Extensions of time (where the applicant agrees to give the council longer) mask the true picture. An application might officially be "decided within target" because the applicant agreed to a 16-week extension of time, even though no reasonable person would call 16 weeks fast.

The councils that consistently meet targets tend to be those with adequate staffing, efficient validation processes, and strong pre-application services that prevent problematic applications entering the system in the first place.

What This Means for You

Whether you are a homeowner planning an extension, a developer assessing a site, or a professional monitoring the market, understanding the planning landscape helps you make better decisions. Knowing that tree applications are common in your area suggests protected trees nearby. Seeing clusters of discharge of conditions applications indicates active building sites. A high proportion of outline applications in a neighbourhood signals land being prepared for future development.

The planning system generates enormous amounts of public data. Every application, every decision, every condition, and every appeal is recorded. The challenge has always been making that data accessible and useful. That is exactly what Planning Signal does.
