Since 18th November 2025, Companies House has been experiencing ongoing issues with its filing systems. While they are working to fix the problems, new faults are appearing as others are resolved. At the moment, this is affecting the filing of CS01s as well as several other document types.

Please be assured that we are in regular contact with Companies House and doing everything we can to ensure time-sensitive documents are submitted on time. We know this situation is frustrating, and we will continue to keep you updated until the issues are fully resolved.
