Hi Mate,
A friend of mine has been in a similar position to you.
The solution he took was either declaring him self banckrupt, or starting a phoenix company (Winding up the old company and Starting a fresh in its place with a similar trading name.)
I think it was the latter option, its completely legal, but I think entry criteria is very specific. Its worth a shot if you haven't got the money.
One bit of advice I will give you is that you 100% should not sell any of your personal assets (House/car) until you've had professional advice.
If you contact a insolvency practitioner they will be able to give you free impartial advice, I think spoke to a few of them, I've attached one to get you started www (.) clarkebell (.) com
