It's a pain and no large error - when I was less experienced than I am now, I got rooked for £15000 from a company who went bust and that in the same year as having to accept a 'commercial settlement' from another company which cost me almost as much in lost revenue. It wasn't the best of years..
Although there are legal remedies for this (s214 of the Insolvency Act provides for personal directors liability if, on the balance of probability, it can be established that the directors knew or ought to have known that they were heading towards liquidation) the duller truth is that everyone else is correct in what's actually going to happen and you're going to end up with nothing.
Have you considered approaching the furniture shop(?) directly to provide for their ongoing work? The increased profit, since you are likely to find a 'middle' price between the amount you're currently getting and what they were paying to the other company would be beneficial to you both and you would be likely to recover your losses over the contract period. Don't worry if you have a restraint of trade clause in your agreement - the impending liquidation of the company pretty much renders that contract useless for either party.
