HomePlanningCheck is an independent service. It is not connected to any council, government department, the Planning Portal, Historic England or HM Land Registry. Results are a screening of the rules and the open data we hold, not a planning decision. Only a Lawful Development Certificate from your council makes the position certain, and anyone can apply for one direct to the council or through the Planning Portal.

Rules: The Town and Country Planning (General Permitted Development) (England) Order 2015, as in force from 27 August 2026. Data: planning.data.gov.uk (Open Government Licence v3.0), HM Land Registry INSPIRE Index Polygons, Historic England, Natural England, PlanIt. England only.
