What is a Universal Credit assessment period?

For people on Universal Credit who want to understand why their payment changes each month.

Applies to: England, Scotland, Wales, Northern Ireland Last checked against official sources: 6 October 2026

An assessment period is the one-month block that Universal Credit uses to work out each payment.

Your first one starts on the day you become entitled, usually the day you claim.
You are usually paid 7 days after each assessment period ends.
Your earnings and circumstances during that month decide what you get.
A change can affect the whole assessment period, not just from the day it happened.
Being paid twice by your employer in one period can lower that month's payment.

How an assessment period works

Universal Credit is worked out one month at a time. Each month is called an assessment period. At the end of it, Universal Credit looks at what happened during that month, such as your pay, your rent and who lives with you. It then works out your payment.

The law says an assessment period is one month, starting on your first day of entitlement. Each new one starts the day after the last one ends.

Example dates

Step	Date
You claim	4 July
First assessment period	4 July to 3 August
First payment (about 7 days later)	around 10 August
Next assessment period	4 August to 3 September
Next payment	around 10 September

That is why the first payment takes about 5 weeks. After that you are paid on the same date each month. If that date falls on a weekend or bank holiday, you are paid on the working day before.

How your pay is counted

Universal Credit counts the take-home pay you actually received during the assessment period. For every £1 you earn, your Universal Credit goes down by 55p (after any work allowance).

This works well if you are paid monthly on the same date. It can cause ups and downs if you are paid on a different pattern.

How often you are paid	What happens
Weekly	4 times a year, one assessment period has 5 paydays
Every 2 weeks	Twice a year, one assessment period has 3 paydays
Every 4 weeks	Once a year, one assessment period has 2 paydays

In those months your Universal Credit will usually be lower. It should go back up the next month.

Big one-off pay. If you earn £2,500 or more over your limit in one assessment period, for example from a bonus, the amount over £2,500 is carried into the next assessment period as "surplus earnings".

Changes during an assessment period

A change can affect your payment for the whole assessment period, not just from the date it happened. So a change near the end of an assessment period can still change that whole month's payment. Report changes straight away in your online account.

If you live in Scotland, Wales or Northern Ireland

Scotland: assessment periods work the same way, but you can choose to be paid once or twice a month.
Wales: the same as England.
Northern Ireland: the first assessment period starts when you claim, and Universal Credit is normally paid twice a month.

Common questions

Where can I see my assessment period dates?

Your monthly statement in your online account shows how much you will get for each assessment period.

Why did I get less Universal Credit this month?

If your employer paid you twice in one assessment period, both payments count, so that month's Universal Credit can be lower.
