How Can You Change Bank Details for Child Benefit Payments in UK?
Keeping your bank details up to date is essential when receiving Child Benefit payments. If you’ve recently changed your bank or building society account, it’s important to notify the correct authority to ensure there’s no disruption to your benefit.
Fortunately, the process is designed to be straightforward and secure. You can manage this change online, by post, or through the HMRC app, depending on what suits you best.
Why Would You Need to Change Your Child Benefit Bank Details?

There are several scenarios where updating your bank account details becomes necessary for receiving Child Benefit payments. Your payments could be delayed or even halted if the change is not reported in time.
Here are some of the most common reasons:
- You’ve closed your current bank or building society account
- You’ve opened a new bank account and wish to receive payments there
- You’re switching to a joint account or a personal account
- You’ve been approved for financial arrangements like a Family Loan
- Your existing account has restricted access or has been frozen
- Your payment method needs updating due to administrative changes
It’s also important to change your bank details if:
- You’re no longer managing your finances personally and a representative is helping
- Your existing account has recurring issues with payment reception
- You’re consolidating accounts for better financial tracking
Ignoring the need to update bank information could lead to missed payments or benefit suspensions. Therefore, acting promptly helps maintain financial stability and ensures your child benefit continues uninterrupted.
What Are the Steps to Change Bank Details for Child Benefit?
Changing your bank details for Child Benefit is a straightforward process. You can either update your information online via the Government Gateway, use the HMRC app, or send a written notification by post.
Choose the method that best matches your accessibility and comfort level.
Update Child Benefit Details Online Through HMRC
The most efficient way to update your bank details is through HMRC’s online service. You’ll need to sign in using your Government Gateway account.
Steps to follow:
- Visit the HMRC service online and click the update option for bank details
- Sign in using your Government Gateway credentials
- If you don’t have an account, create one with:
- Your National Insurance number
- Child Benefit number
- A mobile phone for receiving a verification code
- Confirm your identity using photo ID such as a passport or driving licence
- Enter your new bank details
- Review and submit your changes
- Take a screenshot of the confirmation for future reference
This method is secure and provides instant confirmation of your changes.
What If You Prefer Changing Bank Details by Post?
For those who cannot access online services, writing to HMRC is a suitable alternative. This method is reliable, though slower than the online process.
What you should do:
- Write a letter addressed to the Child Benefit Office
- Clearly mention “change of circumstance” at the top of the letter
- Include your: Full name, National Insurance number, Child Benefit number, Old and new bank details
- Post it to: HM Revenue and Customs – Child Benefit Office: PO Box 1, Newcastle Upon Tyne, NE88 1AA, United Kingdom
- Post the letter at a local Post Office
- Request proof of postage and keep the receipt for records
Although slower, this method is acceptable and valid, especially for those without internet access or facing technical issues.
What Should You Do If You Cannot Access Online Services?

In some cases, individuals may not have reliable internet access or digital devices, making it difficult to update details online. HMRC provides alternative solutions for those who may face technical, mobility, or accessibility barriers.
Use the HMRC Helpline
- Call 0300 200 3100, available Monday to Friday from 8am to 6pm
- Be ready with your Child Benefit number and National Insurance number
- Note down the call details:
- Date and time
- Representative’s name
- Location of the HMRC office they represent
- Confirm the changes verbally and request confirmation details if available
Relay UK for Accessibility Needs
If you are deaf, hard of hearing, or have speech impairments:
- Use Relay UK by dialling 18001 then 0300 200 3100
- The service works via app or text phone
- There’s no extra charge for using this method
Paper-Based Reporting
- If phone access is unavailable, use the postal process described earlier
- Always get proof of postage to show when and how the letter was sent
By providing these options, HMRC ensures that every individual can make changes safely and efficiently, no matter their circumstances.
How Long Does It Take for Bank Detail Changes to Reflect?
Once you’ve submitted the updated bank details, the processing time depends on the method used. Online changes are usually processed much quicker than postal submissions. Typically:
- Online updates via HMRC/Government Gateway reflect within 3 to 5 working days
- HMRC app submissions may also take around 3 to 5 working days
- Postal updates may take 7 to 10 working days, depending on delivery and internal processing
If your change is urgent, online or phone reporting is the best option. Always track the confirmation message or take a screenshot to document the process.
What Should You Do If You Don’t Receive Payments After Changing Your Account?

Missed payments can occur due to errors or delays. If you’ve updated your bank details and notice a disruption in payments, it’s essential to investigate promptly.
Check Confirmation
- Revisit your Government Gateway account or HMRC app dashboard.
- Confirm the bank detail change was properly submitted and officially approved.
Contact HMRC
- Call HMRC’s Child Benefit helpline at 0300 200 3100 without delay.
- Have your reference numbers, NI number, and personal identification details ready.
- Record the date, time, and name of the representative for future proof or follow-up.
Verify Bank Details
- Double-check the exact bank account information you submitted online.
- Ensure there were no typos, wrong sort codes, or account mismatches.
Steps to Rectify
- Resubmit your updated bank details through your HMRC online account if needed.
- Use postal confirmation letters or email screenshots if HMRC requests supporting evidence.
- Ask HMRC to initiate a payment trace if the funds have still not appeared after confirmation.
Taking these steps helps prevent prolonged delays in receiving your Child Benefit and ensures your payments are processed correctly moving forward.
Can You Use the HMRC App for Other Child Benefit Updates?
Yes, the HMRC app offers more than just a place to update bank information. Once logged in through the Government Gateway, you can access a variety of features that make managing your benefit easier.
Using the app, you can:
- Update personal or contact details
- View your Child Benefit letters or messages
- Notify HMRC if your child stays in full-time education after age 16
- Get proof of entitlement for loan or visa applications
- View recent payments and expected payment dates
The app provides a convenient, secure way to stay on top of your benefit without needing to make phone calls or send letters.
Will Changing Bank Details Affect Other HMRC Payments?

Changing your bank details for Child Benefit only updates that specific benefit. It does not automatically update your details for other HMRC-related payments such as tax refunds, Tax Credits, or Universal Credit.
Each of these services operates independently within HMRC’s systems, so any changes must be made individually.
To avoid missed or misdirected payments, you should log in to the relevant HMRC service for each benefit or tax service you receive. For example, update your bank details separately through your Universal Credit account or Self Assessment portal if applicable.
It’s essential to double-check that every payment stream reflects your current bank information. Doing so ensures there are no delays in receiving funds and that all HMRC payments continue to reach your correct account without interruption
Do You Need to Notify Other Departments Like DWP or Local Council?
Yes, updating your bank information with HMRC does not automatically alert departments like the Department for Work and Pensions (DWP) or your local council.
If you receive:
- Housing Benefit
- Universal Credit
- Council Tax Support
- Other local authority-based allowances
You will need to contact each respective body directly to provide your new bank account details. This ensures your entire benefits portfolio remains active and accurate.
Is It Safe to Change Bank Details Through HMRC Digital Services?
Yes, updating your bank information through HMRC’s digital platforms is highly secure. The Government Gateway uses encrypted channels and identity verification protocols to protect personal data.
Security measures include:
- Photo ID verification (passport or driving licence)
- Two-factor authentication using mobile verification codes
- Private access to your HMRC dashboard
These layers of protection ensure your information is kept safe and that changes are only made by authorised individuals. Always log out of your session and avoid using public Wi-Fi to maintain your privacy.
Conclusion
Staying up to date with your bank account information is essential for receiving uninterrupted Child Benefit payments.
Whether you choose to update your details online, via the HMRC app, by phone, or through the post, each method offers a secure path for reporting the change.
Ensuring your payments go to the right account not only avoids delays but also provides peace of mind. Act promptly and use the method that best suits your access and comfort level.
