Cardiff Council is a local planning authority responsible for processing planning applications within its area. Applications are submitted through the council's planning portal and cover a wide range of development types, from householder extensions and change of use to large-scale residential and commercial schemes.
SiteLens tracks the Cardiff Council planning register daily and enriches every new application automatically. Each is AI-classified by category and trade, given an estimated value band and a plain-English project brief, mapped, and checked against constraint flags like flood zones, conservation areas and green belt. Every plan names the agent on the application. Pro adds the applicant's name, matched Companies House records, and the agent's direct email and phone where the council or firm publishes them, so you know who to speak to about the scheme.
You can also browse the council's own planning register on the official Cardiff Council planning portal.
