Advice on recovering an unpaid debt for 7K from a firm applying to be struck off

Hi

I am wondering if anyone can advise regarding how to best go about recovering an unpaid invoice (for £7K of consultancy work) which I carried out about 1 year ago? I had previously done a lot of consultancy work for this company but during the last assignment I worked on it became clear that they were in financial difficulty. I was told at one stage that the firm was having financial problems with the client of the project I was working on and that therefore I was 'working at risk' and that they might not be able to pay me in full unless the client agreed to pay them monies owed. However I was not formally requested to stop by a company director until some months later. Once I was asked to stop work on this project I did so immediately.

Having submitted my final invoice approximately 10 months ago I was then told by a company director that they could not pay the invoice and were considering winding up the company. I then sent my invoice to their registered accountants who did not pay the invoice but duly referred me back to a company director to query whether the invoice was valid. The director then informed me that the invoice would not be paid as they had no money to pay it and it would not be entered on the company accounts as they did not consider it to be valid.

Recently I checked on company house and it appears that about 2 months ago the company applied to be struck off Companies House register. I am now unsure whether there is any possibility to recover this debt and whether it is worth investing money paying the Money Claim Online (MCOL) service fees given this situation?

Any advice would be appreciated.
