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 Halton's published datasets from Open Digital Planning, a community of local planning authorities in England collaborating to modernise 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 standardised, machine-readable datasets that improve the efficiency 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 datasets to assist developers, planners, and the members of the public access to better digital planning services.

Developer Contributions
This platform provides clear, accessible information on Section 106 planning obligations and Infrastructure Funding Statements, helping users understand how development contributes to local infrastructure and community needs. By publishing these datasets in an open, consistent format, we support transparency, improve public trust in the planning process, and enable better analysis of how funding is secured, allocated, and delivered across projects.
