Communications data meaning

What does Communications data mean?
Communications data, in the postal context, describes non-content information about a postal communication and the use of a postal service. In the UK (England & Wales, Scotland and Northern Ireland), it is defined in the Investigatory Powers Act 2016 to include: (a) postal data that is comprised in, attached to or logically associated with a postal communication, whether added by the sender or otherwise (for example names and addresses on packaging, barcodes and tracking identifiers); (b) information about any person’s use of a postal service (for example posting, handling, routing, delivery and tracking events), excluding the content of the communication except for the information within (a); and (c) other information held or obtained by or for a postal operator about the persons to whom it provides the service and relating to that service (often called subscriber or account data). It excludes the content of letters or parcels. The term is central to data retention, acquisition and disclosure powers, and to compliance by postal operators with lawful access requests from law enforcement and intelligence agencies. Usage and scope are broadly consistent across the UK jurisdictions. In Ireland, the phrase is used descriptively; postal services are regulated separately and legislation uses different terminology, although...

IPA 2016 Part 3 communications data: UK public authorities, permitted purposes, data categories and authorisation routes (Investigatory Powers Commissioner and DSOs) - practitioner checklist

The Investigatory Powers Act 2016 (IPA 2016) reshapes the statutory regime governing covert surveillance conducted by public authorities, a regime largely, but not entirely, previously contained in the Regulation of Investigatory Powers Act 2000 (RIPA 2000). This Checklist carefully sets out those public authorities that hold the power to apply for authorisation to obtain communications data under IPA 2016, Pt 3, preserving the established focus and scope throughout. Authorisations to secure communications data may only be granted where defined conditions are satisfied, by the Investigatory Powers Commissioner under IPA 2016, s 60A, by designated senior officers under IPA 2016, s 61, or by designated senior officers in urgent circumstances under IPA 2016, s 61A. In operational practice, the Office for Communications Data Authorisations carries out this function on the Commissioner’s behalf. The table below specifies which public authorities may apply to access communications data, the kinds of communications data they are permitted to request, together with the purposes for which such data may be obtained, whether...

UK GDPR personal data breach management workflow for legal practitioners: assessment, containment and recovery, ICO and data subject notification, record-keeping, stakeholder communications, and post-incident prevention

This flowchart shows how to handle a data protection incident (including a cyber security incident) in line with the UK General Data Protection Regulation (UK GDPR). It mirrors the UK GDPR’s rules on reporting and recording personal data breaches, alongside the Information Commissioner’s Office (ICO) guidance on breach management. It charts the end-to-end breach lifecycle, offering direction and links to the relevant precedents for each step of the process. See Precedents: Personal data breach plan, Data breach report form—internal and Data breach assessment and action plan, which steer you through every stage of this workflow. Note 1—assemble data breach team The initial action is to bring together your data breach team. Decide who in the organisation is best positioned to respond promptly to the incident and who should support the ensuing enquiry. This typically calls for contributions from specialists across the business, including IT, HR and compliance/legal, and may, in some instances, involve engagement with external stakeholders and suppliers.

UK Data (Use and Access) Act 2025: Implications for Pension Schemes—DSARs, Complaints, ICO Powers, ADM, Recognised Legitimate Interests, Marketing, Special Category Data, Purpose Limitation and Practical Steps

What are the most significant changes introduced by the Act that pension scheme trustees need to prepare for? The most notable reforms in the Act that trustees should be ready for are: Data subject complaints: complaints about the handling of personal data must be acknowledged within 30 days and answered without undue delay. ICO enforcement powers: the Information Commissioner’s Office (ICO) now has authority to compel interviews and require the production of documents to assess compliance. Data subject access requests (DSARs): the Act codifies the ICO’s existing guidance, meaning (i) trustees must apply a ‘reasonable and proportionate’ search standard when responding; and (ii) the ‘stop the clock’ rule pauses the one-month deadline for a response. Automated decision making (ADM): the Act allows reliance on the full set of lawful bases — including ‘legitimate interests’ — when non-special category personal data is used for significant automated decisions about an individual, provided suitable safeguards are in place. ...

Ireland: Auto-enrolment/MyFutureFund - hindering risks, data protection cautions and 3.5% qualifying scheme minimum from 2026; employers to review exemption strategies

MyFutureFund The State’s new automatic retirement savings scheme, ‘MyFutureFund’, has attracted significant media attention over the past week. While AE is due to commence within the next few weeks, the principal catalyst is that the Department of Social Protection (the Department) has recently sent letters to various organisations cautioning about the risk of employers ‘hindering’ staff from joining MyFutureFund. Specifically, the Department stated that compulsory enrolment into a company pension scheme, where this is not an explicit contractual term and only modest employer contributions (for example, 1%) are payable, would be treated by the Department as an offence of hindering. These communications have sparked engagement with the Department by employer representative groups and stakeholders across the Irish pensions sector, including the Irish Association of Pension Funds (the IAPF). From that engagement it is evident that employers whose strategy is built on all employees being in exempt employment, and therefore outside the auto-enrolment regime, will need to revisit—swiftly—the practicality and lawfulness of that approach over the coming weeks...

UK GDPR lawful bases for personal data processing: consent, contract, legal obligation, vital interests, public task and legitimate interests, with DUAA 2025 updates and Article 9/10 conditions

STOP PRESS: On 19 June 2025, the Data (Use and Access) Bill secured Royal Assent, transforming into the Data (Use and Access) Act 2025 (DUAA 2025) and taking partial effect on that same date. Provisions of DUAA 2025 dealing with issues such as handling data subject access requests, and granting the power to make further regulations, commenced immediately on 19 June 2025. Other elements, relating to notices issued by the Information Commissioner and certain facets of law enforcement processing, began to apply on 19 August 2025 (being two months from the date of Royal Assent). The bulk of DUAA 2025’s measures will only commence once additional regulations, by way of statutory instruments, are made and brought into force. Parts 5 and 6 of DUAA 2025 operate to revise and update areas of UK data protection and ePrivacy law within the UK, including the United Kingdom General Data Protection Regulation, Assimilated Regulation (EU) 2016/679 (UK GDPR), the Data Protection Act 2018, and the Privacy and Electronic Communications (EC Directive) Regulations...
