Window Permission Checker: Pre-Renovation Assessment Service
A specialized assessment service where homeowners submit photos, measurements, and property details (postcode, build date, listed status) via a simple online form. Within 48 hours, a trained surveyor reviews the submission against their local council's specific planning rules (cached from each council's published guidance) and delivers a clear written assessment: 'Permission needed', 'Permitted development', or 'Uncertain—we recommend contacting your council with X questions'. The surveyor also flags any council-specific quirks (e.g., conservation areas, Article 4 directions).
