Unless it’s an established trader I wouldn’t bother.
I worked for 6 weeks for a guy who had a gardening company. He didn’t pay and after a couple of bounced cheques I took him to a small claims court. He didn’t appear or respond so I was granted full judgement.
He still didn’t pay and it can’t be enforced at this stage. I paid again to have a County Court Judgement after which you can get bailiffs in.
The bailiffs went round demanding money. He asked to pay in instalments so the bailiffs left to ask me if this was OK – it was made pretty clear that they thought this was the only chance of getting money so I agreed.
He didn’t pay and then moved house (he was just renting). I was told it that tracing him would cost more money which they probably wouldn’t get back as he would just move again.
I gave up.
If it’s a bricks and mortar business then it’s possibly worth it, but as the gardener said to me “I can’t give you what I haven’t got”. It cost around £500 to get nothing back.
