Halton Borough Council Open Digital Planning Data Portal

Welcome to the Halton Borough Council Open Digital Planning (ODP) Data Portal

This page provides access to published datasets from Open Digital Planning, a community of local planning authorities in England collaborating to modernize the planning system through data-driven solutions. Supported by the Ministry of Housing, Communities and Local Government (MHCLG), this initiative aims to replace traditional, document-heavy processes with standardized, machine-readable datasets that improve the speed and transparency of planning decisions. The links below offer access to critical spatial information—including Conservation Areas, Listed Buildings, and Tree Preservation Orders—all transformed into consistent national formats to help developers, planners, and the public build and use better digital planning services.
