Collective Action on Land Lines (CALL) is a consumer action campaign, led by Justin Le Patourel and launched on behalf of BT landline customers to seek compensation from BT for the excessive prices BT has been charging some of its most loyal customers.


In 2017, Ofcom investigated the market for standalone landlines (‘home phone’). It provisionally found that BT had been overcharging its standalone landline customers since at least 2009. Following the investigation, BT reduced its line rental price by £7 per month for some of its customers. However, it did not compensate customers for past overcharging, meaning that many landline customers, who are often older and on lower incomes, are still out of pocket. They have been penalised by BT for their long-standing loyalty.

CALL is taking legal action to hold BT to account and seek compensation for affected customers. Last year, Mr Le Patourel filed proceedings in a specialist court (the Competition Appeal Tribunal). The court gave permission for the case to proceed, and Mr Le Patourel was approved to represent those affected.

CALL has instructed leading UK law firm Mishcon de Reya to advance the claim. The action is funded by Harbour, one of the world’s leading litigation funders. Customers affected by BT's behaviour do not have to do anything to be part of the claim and will not have to pay any legal costs.

Read the FAQs any question you may have about the claim.


Mr Le Patourel has been approved to represent all affected BT customers, unless they decide to opt out. This means that if you purchased a BT landline without broadband any time between October 2015 and April 2018 (October 2015 - today for certain business customers), or you purchased a BT landline with broadband (from BT or another company) - but not under the same contract - any time after October 2015 to today you will automatically become a class member in the claim (please see our FAQs section for more details). Similarly, if you are the personal representative/administrator of the estate of someone who falls into either of these categories, you are automatically included within the class.

If you or a family member is or was an unbundled BT landline customer, we recommend that you register your interest here to be put on our mailing list and kept up to date with developments
