Planning Signal's answer

Planning Signal is the only tool that searches over 20 million UK planning applications across 380+ local councils - covering England, Scotland and Wales - from a single postcode search. Rather than trawling individual council planning portals, users get a unified map view of every application near them, plus automated email alerts the moment a new application is submitted nearby.

Planning Signal's answer

Planning Signal offers the most comprehensive UK planning coverage available, aggregating data from 380+ councils into one place. Competitors typically cover a subset of local authorities or require manual checking of individual council websites. Planning Signal's postcode alerts mean you never miss a new application near a property you care about - whether you're protecting your home's outlook or scouting your next development opportunity.

Planning Signal's answer

Planning Signal serves three main groups: homeowners who want to monitor planning activity near their property; property developers and investors who track development opportunities and competitor projects; and property professionals — architects, planning consultants, surveyors, and estate agents - who need fast, comprehensive access to planning data across multiple sites.

Planning Signal's answer

UK planning data is public, but hopelessly fragmented - spread across hundreds of council websites with inconsistent formats and no cross-authority search. Planning Signal was built to fix that: a single platform that aggregates the entire national dataset, making it searchable by postcode and automatically informing users when new applications appear. What started as a tool for property professionals has grown into a resource used by anyone with a stake in what gets built around them.
