BT Group PLC (LSE:BT.A) was in court today facing a class action alleging it overcharged customers £1.3 billion for their landline connections. Brought by former Ofcom executive Jason Le Patourel with funding from Harbour Litigation, it is the first class action to reach court in the UK since changes to the law in 2015 allowed them. The writ alleges that telecom giant BT, after cutting prices in 2018, failed to compensate customers for previous overcharging or those that had separately purchased landline and broadband services.
