I run screaming from going down the court route as it is torture. I will issue section 8 1 day after the rent has defaulted for the second time (as above) and a section 21, the tenant will either then 1) bog off - and I get my house back 2) pay up 3) do nothing.
If you do nothing and have not pursued them for the rent they will take option 3 any way. Bottom line is that you want rid of them, they will never make you rich or happy, and don't kid yourself that anything else is possible. You also need to be strong about this, rent on time and nothing less. These chaps may offer you the carrot of paying rent at the end of the month/in stages/etc, apologise and say sorry this is not acceptable - and ask how much do they have in the bank now, right now. If they have £2.36, ask for it to be paid to you - you need them to take you seriously. My gut feeling is always to get rid of non payers where they have not called you in advance of non payment.
I will offer to buy out a crappy tenant before I will go to court as it is invariably cheaper, having the calm/non argumentative conversation with the tenant explaining that you no longer want them as a tenant often has the right effect.
