Child tax credits confusion

Sunnyseaside

I started new job in November told tax credits. Have had an award letter with payments till April. At the end of the letter is states that after 4 April '££ ' will be paid till further notice. I don't understand this as I thought I would be renewing and does that mean that they could stop soon after that. I did give them my new salary and other income changes so there will be no big changes. I'm worried that they will stop as my income has gone up a lot but I told them that in November. So basically what does 'until further notice ' mean at end of award letter

Perhaps post in the Work, Benefits and Business section would be more prudent?
