Investigation into Tata Communications (UK) Limited

Today we have opened an investigation into Tata Communications (UK) Limited (“Tata”). The investigation concerns Tata’s compliance with requirements imposed under an information request notice (the “Notice”) issued under section 135 of the Communications Act 2003 (the ‘Act’).

On 23 June 2025, Tata was issued with a statutory notice under section 135 of the Act requiring the provision of information to assist Ofcom in assessing compliance with the security duties under sections 105A – 105D of the Act and the Electronic Communications (Security Measures) Regulations 2022. The Notice required Tata to provide information regarding the measures it is taking to comply with its security duties.

Ofcom’s statutory information requests play a key part in Ofcom’s work and the information gathered from these requests informs how we carry out our statutory functions as a regulator. Therefore, it is essential that stakeholders provide accurate and complete information in a timely fashion. Where Ofcom has reasonable grounds for believing that a contravention of a requirement imposed under section 135 of the Act has occurred or is occurring, Ofcom may take enforcement action under section 138 of the Act.

The available evidence suggests that Tata may not have complied with certain requirements imposed under section 135, in that some of the information provided by Tata in response to the Notice may not have been complete and/or accurate.

Ofcom’s investigation will examine whether Tata has failed to comply with its statutory duties in relation to Ofcom’s information requests. 

We will provide updates on this page as we progress this investigation.
