HSBC App — In-App Messaging and Chat

For non-urgent queries, the HSBC mobile app provides a secure messaging service where you can contact the HSBC support team without calling. Response times vary — typically within a few hours during business hours.

To use in-app messaging:

  1. Open the HSBC app and sign in
  2. Tap the Help icon or navigate to Support
  3. Use the virtual assistant for quick answers, or request to speak to a human agent

In-app chat is suitable for: account queries, statement requests, direct debit questions, and general information. For urgent matters — fraud, lost cards, or large transfers — always call.

Reporting Fraud to HSBC

If you think your account has been compromised, act quickly:

  1. Freeze your card immediately — open the HSBC app, go to Manage card, and toggle the card to frozen. This takes effect instantly and is reversible.
  2. Call 03457 404 404 — select the fraud option. The fraud team is available 24 hours a day, 7 days a week.
  3. Change your online banking password — do this via the HSBC app or at hsbc.co.uk as soon as possible.

Types of Fraud HSBC Can Help With

Card fraud (someone has used your card without permission): Freeze the card in the app and call HSBC. They will investigate and issue a replacement card. You’re generally entitled to a refund for unauthorised transactions.

Authorised push payment (APP) fraud (you were tricked into sending money to a fraudster): Report immediately to HSBC. Under PSR rules introduced in 2024, banks are required to reimburse most APP fraud victims — HSBC will open an investigation.

Phishing and impersonation: If you received a suspicious call, email, or text claiming to be from HSBC — report it. Forward suspicious texts to 7726 (free). Never share your PIN, full password, or one-time passcodes with anyone, including callers claiming to be from HSBC.

Visiting an HSBC Branch

HSBC maintains one of the larger UK branch networks among high-street banks. Branches are useful for:

  • Opening certain account types that require in-person identity verification
  • Bereavement services and estate administration
  • Power of attorney and legal account matters
  • Large counter withdrawals or deposits
  • More complex banking queries where face-to-face discussion helps

Use the HSBC branch finder on the HSBC website to check your nearest branch and its opening hours before travelling — hours vary by location and some branches operate reduced days.

HSBC Premier Customer Service

HSBC Premier customers benefit from a dedicated Premier contact number printed on the back of their Premier Mastercard, as well as access to a named Premier Relationship Manager who provides personalised support.

Premier customers can also access HSBC Premier Centres — dedicated banking centres in major cities with private meeting rooms and extended service hours.

How to Make a Formal Complaint to HSBC

Step 1 — Contact HSBC

Raise your complaint by:

  • Calling 03457 404 404
  • Sending a secure message via the HSBC app
  • Writing to HSBC’s customer relations address (found on the HSBC website)
  • Visiting a branch

Be clear about what went wrong and what outcome you’re seeking. HSBC must acknowledge your complaint promptly and issue a final response within 8 weeks.

Step 2 — Financial Ombudsman Service (FOS)

If HSBC’s final response doesn’t resolve your complaint — or if 8 weeks pass without a resolution — you can escalate to the Financial Ombudsman Service for free:

  • Website: financial-ombudsman.org.uk
  • Phone: 0800 023 4567 (free from UK landlines and mobiles)
  • The FOS is independent, impartial, and its decisions are binding on banks

You must go through HSBC’s complaints process before the FOS will accept a case.
