We recently had an instance where we were unable to file accounts for a client company through VT Filer. The filing failed, giving us a very uninformative error message. We later found out that the Companies House service was unavailable between 8am and 8pm on the filing deadline (a Saturday). We filed the accounts at the beginning of the following week and appealed the inevitable penalty. Companies House rejected the appeal, saying that we should have been aware that the service was unavailable (we weren't) or could have filed between 8pm and midnight on the Saturday (perhaps, if we'd known that it would resolve itself at 8pm) and, sticking the boot in for good measure, saying that leaving it until the last minute "seems unnecessarily risky".
Anyone have experience of this? It seems a bit harsh to me, but should we just accept it and move on?
