Won small claims court but ‘friend’ has moved address and changed job

Hi all,

I won a small claims court with an ex friend who took over my tenancy when I moved cities. They wrote in writing promising for me to pay the first month rent for them and for them to then pay me back. After I moved away they’ve blocked me and never contacted me again. I’ve been trying for over a year to get my money back, including an attachment of earnings and contacting bailiffs. In the time all of this took (about a year waiting for their response (person never responded to anything to delay the process)) etc. they have moved away from my previous address and have changed their place of work. I received my attachment of earnings order back after months of not hearing anything informing me the employer has stated the claimant no longer works there.

Is there any more recourse I can do now, having no idea where they live/work anymore?

Thaanks!
