You should report changes such as moving home, rent or household changes, starting or ending work, changes in earnings, savings, childcare costs, health or caring responsibilities, and changes to your bank details. Report a change as soon as it happens through your Universal Credit online account, keeping any evidence and explaining the date it took place. Changes can affect your entitlement and may lead to an overpayment or underpayment if they are not reported promptly. If you are unsure whether something matters, leave a journal message or check the latest guidance on GOV.UK.
