TSB Customer Service Number — Complete Practical Guide

Overview: Why knowing the right TSB contact channels matters

Contacting TSB (TSB Bank plc) efficiently saves time, prevents fraud escalation, and ensures faster resolution for account, card, mortgage, or business-banking issues. TSB offers voice, in‑app and web channels; each is routed differently depending on the problem (general enquiry, lost/stolen card, fraud, complaints, business queries). For security and compliance reasons, some enquiries must be handled by phone and cannot be resolved by email.

Before calling, note that UK banks increasingly route customers through automated menus and identity checks. Having the correct contact number and the right documents ready reduces average handling time and increases the chance of immediate resolution rather than escalation to a specialist team.

Primary TSB contact points and where to find the official numbers

The definitive source for current TSB telephone numbers and service hours is TSB’s official contact page: https://www.tsb.co.uk/help/contact/. As of mid‑2024, the commonly published UK general customer services number used by TSB was 0345 835 0444 (local‑rate). Because banks periodically change routing and add dedicated lines (for cards, mortgages, business banking and overseas callers), always confirm the number on the TSB website or in the TSB mobile app before dialing.

TSB also provides secure messaging via the TSB mobile app and online banking for non‑urgent enquiries. For time‑sensitive matters (lost/stolen cards, suspected fraud or account compromise) phone contact is preferred because it allows immediate card blocking, account restrictions and rapid escalation to the fraud team.

Lost, stolen or compromised cards — phone actions and typical timings

If you suspect a debit or credit card has been lost or stolen, call TSB immediately to block the card. Blocking a card typically prevents further ATM withdrawals and contactless payments within minutes; physical card replacements are dispatched by next‑day delivery in many UK postcodes, or within 3–5 working days in some regions. When calling, expect to confirm identity (name, date of birth, sort code and account number or last four digits of the card) before action is taken.

For suspected fraud, TSB’s fraud investigators will often issue a provisional credit while they investigate — this can take 5–10 business days for most cases, longer if external partner banks are involved. Keep records of suspicious transactions (dates, merchant names, amounts) because detailed information accelerates the investigation and reduces the need for repeated calls.

What to have ready when you call — critical data and security checks

Prepare the following before you dial: full name as on account, date of birth, current address, sort code and account number (or last four digits of the card), recent transaction details (three most recent successful or questionable transactions with exact amounts and dates), and a telephone number reachable during investigation. Providing this upfront shortens identity verification and resolution time.

TSB will not ask for your full online banking password. They may ask for memorable information or to confirm a recent transaction to authenticate you. Never disclose full PINs or one‑time passcodes (OTPs). If any caller — even someone claiming to be from TSB — asks for OTPs or full passwords, end the call and contact TSB using the official number on tsb.co.uk.

Complaints, escalation and external recourse

If your issue is not resolved to your satisfaction by frontline teams, ask for a complaints reference number and the name of the manager handling the case. TSB has an internal complaints process that typically issues a written response within 8 weeks for complex cases; simpler complaints often receive resolution within 5 working days. Request timescales and a clear next step when you first raise a complaint.

If you remain dissatisfied after exhausting TSB’s complaints procedure, you can refer the dispute to the Financial Ombudsman Service (FOS). Useful FOS contact details: phone 0800 023 4567 (UK freephone) or 0300 123 9123; postal address Exchange Tower, London E14 9SR; website https://www.financial-ombudsman.org.uk/. The FOS is independent and can award compensation where appropriate.

Practical channels and tips — how to choose the fastest route

• Phone: Best for lost/stolen cards, suspected fraud, urgent account closures or when immediate action is required. Expect identity checks and, depending on call volume, waits of 5–25 minutes in normal conditions; peak times (Mondays, early mornings) can be longer.
• TSB mobile app & online banking secure messaging: Ideal for non‑urgent requests (document uploads, account queries, balance corrections). Messages create a case reference and track progress; response times are usually within 24–48 hours for routine enquiries.
• Complaints process & escalation: Ask for complaint reference, expected timescale, and manager details. If unresolved within the provided timeframe, collect all correspondence and escalate to the Financial Ombudsman Service after 8 weeks or sooner if told you have a “final response.”

Specialist lines, business banking and international callers

TSB runs separate teams for business banking, mortgages and specialist wealth services; these specialist lines reduce handling time because staff have sector‑specific authority. If you are calling about a business account, request transfer to the business banking desk and have company registration number and director ID ready.

International callers should use the dedicated overseas contact number listed on TSB’s contact page or use the secure in‑app message if you have access — international routing and fraud prevention steps differ and may require additional identity proofing (e.g., invoice copies, utility bills with international formatting).
