A client is a subsidiary of an Irish limited company.
The UK sub has had its Authentication code changed by Companies House for some reason. I have never had it changed before for any of my other clients. The one we used last year to submit the accounts no longer works.
I have applied for the code to be sent to the registered address but the registered address on Companies House is no longer the address and so the new Authentication code doesn't arrive. (long story - company secretarial stuff was done by HO in Dublin)
Does anybody know how to get a new code when the address on Companies House is no longer correct?
