The Short Answer
Your first PIP payment is paid on the date given in your decision letter and then every 4 weeks on the same weekday, with any back pay from your claim date normally arriving as a separate lump sum. The arrears often arrive before the decision letter itself, because payment instructions move faster than post. Reading each transfer separately, against the letter, resolves almost every query about the amount.
The Two Transfers
The table below sets out the position, with each figure taken from the source named beneath it.
| Payment | What it covers | When |
|---|---|---|
| Arrears | The period from the award start date to the decision | Normally within days of the decision, often before the letter |
| First regular payment | The current 4-weekly cycle | On the date the decision letter sets |

An unexplained DWP credit shortly after a decision is almost always the arrears. Payment instructions move faster than post, which is why so many people see the money before they see the reason for it. Why the lump sum can land first is covered under back pay timing.
What the Letter Tells You
GOV.UK states that a decision letter gives "the date of your first payment", "what day of the week you'll usually be paid", "how long you'll get PIP for" and "when and if your claim will be reviewed".
Those first two lines are what to check the bank against. The weekday is fixed for the life of the award, and every later payment falls 28 days after the last.
Why the First Amount Can Look Odd
Three ordinary reasons.
It may be the arrears rather than the regular payment. It may cover a part-period between the award start date and the first full cycle. Or, where an award was already in payment and has been increased, it may be the difference rather than the full rate.
A single deposit matching neither figure is usually two payments combined. Comparing each transfer separately against the letter, rather than comparing a total, is what makes the arithmetic work.
Then Every Four Weeks
Thirteen payments a year, not twelve. Because 28 days is not a calendar month, the date moves earlier through the month each cycle. A payment on the 3rd falls on the 31st of the next month, then the 28th.
Where a due date falls on a bank holiday, GOV.UK states you will usually be paid before it and afterwards continue as normal — so the cycle itself does not shift. From the first date in your letter you can work out your payment dates for the year ahead.
If Nothing Arrives
Allow a few working days past the date in the letter. The PIP enquiry line on 0800 121 4433 (Monday to Friday, 9am to 5pm) can confirm when a payment was issued and to which account.
Those two facts separate a DWP problem from a bank problem, and each has a different next step, set out in PIP Payment Late or Missing.
Checking the Arrears Figure
The arrears are the weekly rate multiplied by the weeks from the award start date, segmented where the period crosses an April. How the owed-from date is fixed is on rules and triggers, and the cycle itself is on payment schedule explained.
