OFCOM has opened an investigation into BT’s compliance with its obligation to provide customers with clear and simple contract information before they sign up to a new deal, the regulator has announced.

Telecoms providers have been required to give customers contract information and a short — usually one-page — summary of the main contract terms before signing up since June last year.

But in October, Ofcom opened an investigation into EE — which is part of the BT group — after it suspected it may have failed to comply with the requirements.
