Why am I denied access to the Tesco website?

An "Access Denied" error on Tesco usually happens when Tesco's security system blocks your IP address or flags your browser settings.

Common Causes

  • VPN or Proxy Use: Tesco blocks many Virtual Private Networks (VPNs) and overseas IP addresses to prevent automated traffic and protect its systems.
  • IP or Network Blocking: Your internet service provider (ISP) or home router IP might be temporarily restricted by Tesco's firewall due to high traffic flags.
  • Browser Compatibility: Certain browsers (like Firefox or privacy-focused setups) or strict ad-blockers can trigger security blocks on Tesco login pages.
  • Failed Login Lockouts: Entering incorrect account or Clubcard details multiple times can temporarily restrict your access.

How to Fix It

  • Turn off any active VPN.
