Millions of parents in the UK will be temporarily unable to access their Child Benefit details online while HM Revenue & Customs carries out planned maintenance on its digital service. The shutdown affects the online tool used by claimants to check and update information linked to their claims.
The service will close from 10pm on Friday 18 September 2026 until 2am on Saturday 19 September 2026. HMRC has said the closure is limited to online access and does not affect Child Benefit payments.
Scheduled Maintenance Limits Access to Child Benefit Tools
Parents who need to report changes to their circumstances or manage their claim online will have to wait until the service reopens. According to HMRC’s service availability guidance, the Child Benefit service is otherwise operating normally, with no other reported issues.
HMRC said: “Due to scheduled maintenance, you will be unable to access our online service from 10pm on Friday 18 September 2026 to 2am on Saturday 19 September 2026.” The tax authority added: “We apologise for any inconvenience this may cause.”
The online service allows parents to make changes that could affect their Child Benefit claim. This includes updating details connected to their entitlement. For most families, Child Benefit is paid every four weeks.
The warning does not indicate a suspension or delay to payments. It relates only to the availability of the online platform during the maintenance window. Parents who need to make changes to their claim have been advised to avoid waiting until the period when the service is unavailable.
Child Benefit Claims Can Also Affect National Insurance Credits
Child Benefit provides financial support for families, but claims can also be linked to National Insurance credits. These credits can count towards a person’s State Pension entitlement, according to information provided by HMRC.
This can affect parents who stop working or reduce their working hours while caring for children. A Child Benefit claim may allow them to continue receiving National Insurance credits during periods when they are not paying National Insurance through employment.
The online service is also used by parents making new claims or adding another child to an existing claim. According to HMRC, a claim can be made 48 hours after a child’s birth has been registered or once a child comes to live with the claimant.
Parents applying for Child Benefit may need their child’s birth or adoption certificate, bank or building society details, and their National Insurance number if they have one. A partner’s National Insurance number may also be required if they have a partner.
HMRC states that Child Benefit claims can be backdated for up to three months from the date the claim is made. Parents without a birth or adoption certificate can still apply, though the process may take longer and HMRC may later request the document as evidence. The planned closure is a short interruption to the digital service rather than a change to the benefit itself. Once maintenance is complete, parents will be able to return to the online platform to manage their claims as usual.
