I've received a tax rebate. Will I still qualify for the next CoL payment?

I am new to the forums.
I have recently been awarded a tax rebate because I was taxed on my small railway pension.
I believe my UC  award this month on 17th September will be nil, as the tax rebate will be classed as income.
What I am worried about is that although not yet released the 2nd qualifying period dates for the cost of living payments, and because my award this period will be nil.
Will I still qualify for the next payment, as although I have received the tax rebate,the payment will actually pay my rent.
