How do I enforce a CCJ?

Have you considered talking to no win no fee debt collectors?
Although they were unsuccessful a Company called Bright Future Solutions did stick to their word and refunded my up front fee when they failed to get a result after a year.
Swift Resolutions also seem to have their finger on the ball, though I haven't used them for debt collection yet.

I haven't used any, but this is the way I would go too. A few years back, I made a note of Direct Collection Bailiffs Ltd.

Do a new MLOL. Even if you don’t get the £3k plus additional court costs it will be another 6 years to piss him off.

If he’s unlikely to sell his rental property you won’t get the money, and if sells below his BTL mortgage costs, but again will piss him off if there’s an additional charge against it. It’s not difficult to do.

I am afraid after 5 and a half years you will struggle to get your money. The debt write off limit is 6 years and all the tenant has to do is ignore you for 6 months and thats it. Many of us have been there, and you need to know when to throw in the towel. The thing is not to take it personally or you will throw a lot of good money after bad. I have been stiffed a few times in my 25+ years of letting (non payment , property needing refurb after letting). the first one I took personally but she avoided paying. The only success I really ever had was getting a guarantor to cough up over £2k, and he was so disgusted with his daughter and her partner he cut them out of his will and left everything to his grandkids.

I agree with Judith Wordsworth, take out a further CCJ before the old one runs out, that gives you another six years in which you may get paid. And as has been said will piss him off even more.

Bite the bullet and give it up ya p1$$ing good money up the wall l right it off when l get caught, that's the advice l recieved off my solicitor who is a personal friend these people are rats .

Further CCJs will influence the credit rating of that delinquent so its not just an annoyance rather has real world consequences to their ability to borrow and also protects potential lenders from such delinquent behaviour.

Not direct benefits to your business but the right thing to do at the cost of MCOL fees.

Accountability matters.

I used DCBL for 2 CCJ’s. After 3 half hearted attempts they advised they were unseccessful and charged me a fee. Totally useless and so different from their “on screen” successes.

You CANNOT take out another CCJ for the SAME debt, you would need to have further claims of cash to process eg further fees like tracing fees or debt collection fees incurred in trying to recover the original debt

It sounds like you're going down the Oral examination route but a charging order is probably the most effective way to secure payment of your unpaid CCJ. Alternatively, wait it out as the CCJ will remain enforceable for up to 6 years.
For what its worth, we use Frontline Collections for all Rent Arrears debt collection with a great degree of success. They provide the full shaboom for debt collection services from start to finish. Frontline Collections have also executed unpaid CCJs for us on a regular basis which is extremely cost effective.
