Assessment periods and payment dates explained

Your first assessment period begins on the day you make your claim and runs for one calendar month. Every period after that follows the same pattern, and your payment is made seven days after each one ends. So the date you happened to click submit fixes your payment date for as long as the claim lasts. Claim on the 3rd and you are paid around the 10th every month; claim on the 28th and you are paid around the 4th. There is no way to change it afterwards short of closing and reopening the claim.

Because Universal Credit is paid monthly in arrears, the first payment arrives about five weeks after you claim: one full assessment period, then seven days for processing. That gap is the hardest part of a new claim, and it is why advances exist. An advance is not extra money, it is your own future payments brought forward and repaid over the following months, but it is interest-free, and for most people the choice is between an advance and something worse.

If your payment date falls on a Saturday, Sunday or bank holiday, you are paid on the last working day before it. The assessment period does not move, only the payment does, so the following month goes straight back to the usual date. Around Christmas this can mean a payment arriving several days early, which is welcome at the time and leaves a longer gap before the next one.

Earnings are allocated to the assessment period in which your employer reports them to HMRC, not the period you worked. If you are paid weekly, fortnightly or four-weekly, some periods will contain an extra pay date, and the taper treats the whole lot as one month's earnings, so that month's award drops sharply and the next recovers. The same thing happens when an employer pays early before a bank holiday. It evens out, but it is brutal on a monthly budget if it is unexpected.

A change takes effect from the assessment period it falls in, not the day you report it. Report a rent rise, a new child, a change in hours or the end of a job as soon as it happens: report it late and you lose the money for the periods that have already closed. The rule cuts both ways. A change reported late that would have reduced your award creates an overpayment you have to repay, so the journal entry is worth making the same day.
