As the court date is so close, I think you should not pay the �14.
Do as much preparation as already discussed.
Tell the court that it was never your intention to permanently deprive the council of its �14, that you have always tried to ensure the rent is paid and time, and where you have fell into arrears you have paid in full as soon as possible.
Also, make a record of all your income - include every penny you get . Show as a monthly total, after taxes and so on.
Do the same for your outgoings - include rent, council tax, gas, electric, water rates, phone, tv licence, car tax, car insurance, house insurance. Everything that has to be paid that is essential. Divide yearly bills by 12 and show how much all of this is each month.
Finally, make a list of all other monthly outgoings - loans, hp, that sort of thing.
Now you will be able to clearly show the court how much spare cash you have for food, clothing and other living expenses.
I think you will be able to make the council look quite foolish.
And afterwards make your formal complaints.
