You can phone this number to find out if receiving child benefit will impact the benefit cap, or see if you qualify for National Insurance credits.


When you phone the number above explain your personal situation, whether you’re the biological parent of the child or not, if you’ve recently moved to the UK, or are living abroad, there’s still a chance you could be eligible for Child Benefit.

Make a claim

You will need to send the child’s birth o adoption certificate too. You can backdate child benefit pay for up to three months.

It can take up to 12 weeks for your first payment to be processed into your account.

Change in circumstances

You must phone this number to report changes like starts working for more than 24 hours a week, goes abroad permanently, gets married, changes their name, goes to prison for more than eight weeks, and more.

Payment issues

The child benefit is typically paid every four weeks on a Monday or Tuesday, but that will change if the money is due on a bank holiday. If your money is due on a Bank Holiday, ring the number above to find out when your next payment date will be instead.

Your first payment might take a while to come through, up to 12 weeks, but if you still haven’t received it after this time you can phone the number above.  Your child benefit will be backdated for up to three months as well.

Death of a child or parent

You will typically still receive child benefit for eight weeks after the child dies, when reporting the death of a child you will have to include the date of death.

In the event of a death of one or both parents, child benefit is still available to those who become the main carer of the child or children. You’ll have to ring the Child Benefit Office on the number above to let them know about the death. Child Benefit will then be cancelled and you’ll ahve to make a new claim for child benefit if you’re not the person named as the claimant on the original form. In the event of this you might be eligible to receive Guardian’s Allowance or Widowed Parent’s Allowance on top of the child benefit.


When you phone this number the office can help deal with complaints about the level of service you’ve received, mistakes that have been made or reasonable delays you’ve experienced. When you speak to them on the phone you will have to provide some personal details, like your National Insurance number, as well as details of what happened and how you’d like your complaint settled.

If you’re not happy with the outcome of the complaint you can ask the Child Benefit Office to review their response, and then contact the Independent Adjudicator if you’re unhappy with the final response.
