Hi Simon,

We’re aware that HMRC are moving to TLS v1.2 and will not be allowing TLS v1.0 or v1.1, so we need to ensure our software is compatible with v1.2 to allow successful submissions.

Are Companies House following suit with the iXBRL submission servers? If so, do you have any dates for this and will you also be blocking the earlier versions?

Thanks,  
Sue

Sue,

We have no plans for this, but it is something we probably need to look into.

I hope this clarifies.
