Rocio Concha, Which? Director of Advocacy and Policy, said:
“Effective collective redress is something Which? has long campaigned for, and while no claim under the regime has reached a full trial yet, it is encouraging to see this case against BT progress, and hopefully be allowed to proceed to a full trial.
“If successful, this opt-out action would be good news for many BT customers who were found to have been historically overcharged for years, but saw no refund as a result.”
