Following the successful national rollout of our new digital service, we are now entering the next phase of our transformation. The legacy Appeals Casework Portal (ACP) has stopped accepting new planning and enforcement appeals, as we move closer to a fully integrated digital end-to-end service.
Advancing our digital transformation
The transition to the ' Appeal a planning decision ' service marks a significant step in our journey to modernise the appeals process. Built to meet the latest Government Digital and Data standards, the new platform provides a more intuitive, secure, and resilient experience for appellants, agents, and local authorities.
What this means for users
The legacy Appeals Casework Portal (ACP) is now being phased out. Depending on your appeal type and when you started your application, the following applies:
New appeals: Most planning and enforcement appeals must now be submitted via the new digital service.
Existing appeals: If you submitted an appeal on ACP you can still log in to view its progress and manage your case.
Unsupported appeal types: A small number of specialist appeal types are not yet hosted on the new service. We are working to onboard these throughout the 2026/27 financial year.
How to submit an appeal
The following appeal types are already supported on the Appeal a planning decision service:
- Householder
- Planning
- Listed Building
- Commercial Planning
- Commercial Adverts and Advertisements
- Enforcement Notice
- Enforcement Notice Listed Building
- Lawful Development Certificate
