| Companies House filing issue |
Last week we received reports from customers that submission of accounts and Companies House forms within the software, were not being processed or acknowledged. Any submission made after 20:00 / 8:00pm on Wednesday 10th June, were placed into a queue but no acknowledgements were returned. On Friday 12th at approximately 22:00 / 10:00pm, Companies House suspended all online filing services entirely. As a result, any submissions attempted since that point will not have reached Companies House. We ask customers not to attempt to resubmit or submit any new documents at this time. We can confirm this is an issue on the Companies House side and is not limited to IRIS software and all software vendors are affected. We are actively working with Companies House to help resolve the issue as quickly as possible. There is no need to contact our support team. If you are concerned about a late filing penalty because of this issue, please be aware that Companies House does have an appeals process available. We apologise for the inconvenience caused and will keep you informed. |
