PSC/PSC Statement Streaming API issue

API Issues
1

My team have noticed that PSC statement events (persons-with-significant-control-statements) are now being published to the PSC (persons-with-significant-control) streaming API, however, we cannot see anything to indicate that this is an intentional change on the part of Companies House. We have also observed that no messages have been published via the PSC Statements streaming API since 19/05/2025 and are wondering whether some error has occurred causing these updates to be published to the wrong stream?

This issue is causing us some issues with our consumption of the streaming API, please could you let me know whether this new behaviour is expected so that we can decide if we need to make changes to our stream consumption architecture.

Thanks,
Tyrese

No data on the PSC stream since the 19th? This is what one of my systems saw on that stream (for every hour since the 19th)

We are currently investigating an issue where it looks that customers can get Persons- of significant-control but not Persons- of significant-control-statements.

I will update once the service is restored or I have further information.

I think you’ve misunderstood my post a little bit, I’m not saying that there is no data on the PSC stream, quite the opposite, in fact. The stream that I’m saying has no data is the PSC Statements stream (persons-with-significant-control-statements) - this is the stream that has not had any data published since the 19th. The issue on the PSC stream is that resources from the PSC statements stream seem to have been erroneously published on this stream

Thank you Darran, are you able to confirm that events from the persons-with-significant-control-statements stream have been published to the persons-with-significant-control stream?

6

The service should now be fully operational. Apologies for the inconvenience.

7

Lovely, thank you for the update. Will you be publishing any events missed through the persons-with-significant-control-statements stream?

8

I did misunderstand. All is good now I see.
