Im not sure which tariff that you are meaning here.
There is a Spreading Warmth Tariff that indeed has met its quota which was earnings of under £13,500 per annuam household income, children under 16, pensionable age etc etc.
If you are now earning below that quota now but the tariff is no longer available then theres not a lot you can do. Also to say that they hand out this option to anyone they choose is unfair, they will rely on what information the person gives and make judgement from there. Its like a benefit from the government, most people slip through the net simply by not telling the full story and let down people like yourself who, if the Tariff was not now withdrawn would certainly have been entitled to.
The First Step option is indeed that, you need to have a debt in place and unable to make enough payments towards the account due to your circumstances. I understand that you feel they should be stopping people coming into debt. If you have zero on your account, the assumption will automatically be that you arent in a debt situation.
How can they prevent a 'debt', they cant predict your bill. They have to have something to work with so they can get a pattern of your usage and also break that debt down over a period of time.
When you get your next balance, get on the phone and tell them simply you WANT to pay your bill but your situation means that you are unable to do soor unable to meet the minimum required (esp payment plans). Then they can look into what arrangements can be made, lower your unit tariffs and they also review your accounts after six months to see if they helps is still needed or that you can now manage.
I dont mean to be picky here but just remember, the Tariffs are on a high probability signed up for over the telephone. Its not like a visit is made by a doctor etc to assess if you are entitled. Unfortunately there are people who grab as much as they get, dont actually consider they dont really need the help and let down folks who are in awkward situations not of their doing.
