The format of the accounts filed at Companies House via Sage for Accountants looks very unprofessional. The format materially differs from the copy generated for issue to clients. Which can only mean that the problem is from the iXBRL tagging. Please look into this as it is off-putting to clients to see such formats on the public register of Companies.
Fixing this manually is impossible without the time consuming work of identifying and tagging accounts manually before submitting, which carries the risk of errors and rejection from Companies House.
This is also relevant to full accounts. And this is more concerning as the option to file paper copies of accounts at companies house is being phased out
