Very little to be honest.
You could try asking your bank to see if there is any point in presenting the cheque. They used to do in the past, but I am not sure if they still do it.
A cheque is an acknowledment of a debt, so it makes suing the creditor much easier. They can't dispute that they owe you money.
However, there is no point in going to the expense of a getting a court order if they are going bust.
How much is it?
If it's a large amount and it's a limited company, you could ask your solicitor to petition for their liquidation. This may prompt them to pay you.
