Using VPNs and region locks

  • Platforms like BBC iPlayer, Peacock and 10 Play are region-locked and normally require you to be in their respective countries, along with a local account.
  • Some guides suggest using a VPN to appear in the right region, but availability, legality and quality can vary by provider and local law, so users should check their own country’s rules and each service’s terms of use.
