What to do when your debtor may be voluntarily liquidating?

[Wpalzm]

I won a case against a small Limited Company. They have refused to pay, and then informed me that they are liquidating. However according to The Gazette and Companies House, they are currently active and not yet going through liquidation. However it does look from their website as though they have stopped trading.
I had been intending to get a warrant of control to recover the payment, but it seems unlikely now that this would be successful.

Should I contact the liquidators?
Should I serve and SD1 statutory demand?
Should I complain to the government Insolvency Service?
Any other steps forward from here?

FWIW, the company director will lie and cheat and play games at every turn. So I cannot be convinced that any of his actions are genuine.

Ask who the liquidator is and when the creditors meeting is to be held. And yes, if you are told who the liquidator is, contact that person.
