If I have a customer who doesn't pay, I don't mess about but go directly to MCOL. It's painless, adds the cost to the debtor, and once they get the court paper work through, it often scares them into paying. If they don't pay, not only do they end up with a CCJ against them, but if they try to sell the property, raise money against it etc, the Land Registry will flag up that there is an outstanding debt on it which will have to be settled first.
However, I can't understand why you left it so long, don't do so again; however you have 6 years to get his sorted so do so now, hit him with MCOL, do not use a solicitor unless MCOL fails as you'll be paying through the nose for something that can be done without that extra cost.
