Universal credit question

[TTCbaby2x]

I am currently claiming UC while on unpaid maternity leave.

I have had to hand my notice in as my son is disabled and I am his carer. My end of employment date is 21/04 and I am going to be receiving a one of payment from my employer on 25/04 for holiday pay they owe me from 2024. This will be around the £1800 mark.

I currently receive around £580/£600 UC per month. My question is when I receive this one off payment from my employer, how many months will they drop my UC to £0 for? I assume the first month it will drop to £0 because of the one off payment that month but the following month will they drop it to £0 too? Essentially the one of payment from my employer benefits me in no way then as I am being deducted UC to cover this full payment?

Also another question, the month my UC drops to £0 do I have to reapply for it again for the following month, will they cancel my UC claim? Or as it's a one off will they keep my claim open and pay me as normal the following month?

I'm not sure how it works and would appreciate any advice.

It won't affect subsequent months at all. It only would if it were more than £2500 over the amount needed to take your UC for the first month to zero, so you're fine

And no, you won't need to reapply. Claims stay open for a few months of zero payments (I think six months)

Though be sure to log into your account to double check

UC will treat it as earnings in the assessment period that HMRC tell them it is received, so in theory it should only impact 1 month, and for a one off month I don’t believe your claim would be cancelled no

They should keep the claim open and only drop you for one month. I work but I get a top up for childcare costs and every year I get a bonus that takes me way above the threshold, so the following month I get £0 and then I get it back again.
