Latest Update: Deadline to opt out 11 November 2022


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 provisionally found that BT had been overcharging its landline ('home phone') customers. As a result of Ofcom's investigation, BT agreed to reduce its line rental price by £7 per month for some of its customers.

However, BT did not offer to compensate its customers for its past wrong-doing, meaning landline customers are still out of pocket. Many of these customers are older and from low-income brackets, essentially they have been penalised by BT for their long-standing loyalty.

CALL has taken legal action to hold BT to account and seek compensation for BT's customers. In order to do this, Mr Le Patourel recently filed proceedings in a specialist court (the Competition Appeal Tribunal) which seek to have him appointed to represent the group of individual consumers harmed by BT's unlawful behaviour.

CALL has instructed leading UK law firm Mishcon de Reya to advance the claim and is funded by Harbour, one of the world’s leading litigation funders, to fund the legal action.

BT's customers affected by BT's behaviour do not have to do anything to be part of the claim and will not have to pay legal costs.

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



If you purchased an unbundled BT landline from 2015 onwards, it is very likely that you may have been subjected to unfair pricing (please see our FAQs section for more details).Mr Le Patourel is seeking to automatically represent all BT customers who purchased an unbundled BT landline from 2015, unless they decide to opt-out. This means that if you purchased a BT unbundled landline from 2015 onwards, or if you are the personal representative/administrator of the estate of someone who has, you will automatically become a class member in the claim.
