Competition Law and Layered Platform Dominance Theories

1. Introduction

The UK smart-meter rollout is a statutory and licence-based programme for replacing traditional gas and electricity meters with interoperable digital meters capable of remote communication. In Great Britain, the framework combines the Energy Act 2008, Electricity Act 1989, Gas Act 1986, Energy Act 2023, supply-licence conditions, Smart Energy Code (SEC), Data Communications Company (DCC) licence, and consumer/data-protection rules. The objective is not simply meter replacement: smart metering supports accurate billing, demand flexibility, market innovation and a more digital electricity system.

2. Statutory Foundation

Section 88 of the Energy Act 2008 gives the Secretary of State powers to modify energy licences and industry codes for smart-meter purposes. Section 91 and related amendments created licensable smart-meter communication activities. The Energy Act 2023 extended the principal section 88 powers to 1 November 2028. The DCC communication service is itself licensed, while the SEC establishes detailed rights, technical requirements and obligations governing communications between meters, suppliers, network operators and authorised users.

3. Current Rollout Obligations

The 2022–2025 annual installation-target framework has ended. For the post-2025 domestic phase, the Government decided that suppliers must take “all reasonable steps” to complete installation of smart meters in remaining domestic premises by the end of 2030. Suppliers must also submit deployment plans to Ofgem; binding annual milestones for new installations and relevant replacement activity are intended to operate from January 2027. Suppliers must additionally take reasonable steps to restore meters operating in traditional mode to smart mode within 90 days after becoming aware of the problem, subject to the applicable framework.

For non-domestic premises, the post-2025 regime introduces smart-contingent contracting. From 1 September 2027, new fixed-term contracts for designated smaller non-domestic premises must generally include a term requiring the customer to have, or agree to have, an eligible smart or advanced meter. Communication and consumer-protection obligations also apply under the new framework.

4. Consumer Protection, Installation and Data

Rollout duties do not eliminate consumer-protection obligations. Installation activity is governed through licence conditions, the Retail Energy Code and the Consolidated Metering Code of Practice. Smart-meter consumption data may constitute personal data. The Data Access and Privacy Framework, Data Protection Act 2018 and UK data-protection regime therefore restrict access and use. More granular domestic consumption data generally requires stronger consumer choice or consent, particularly for half-hourly access and marketing. DCC access is also controlled through the SEC.

5. Case Law

Case Name/Citation: R (British Gas Trading Ltd) v Gas and Electricity Markets Authority [2019] EWHC 3048 (Admin)

Facts: British Gas challenged aspects of Ofgem’s methodology when implementing the statutory default-tariff price cap.

Legal Issue: Whether GEMA had lawfully exercised its statutory regulatory powers and properly addressed the statutory requirement concerning efficient suppliers’ ability to finance licensed activities.

Judgment: The High Court accepted important parts of British Gas’s challenge and granted declaratory relief.

Legal Principle/Ratio: Energy regulators exercising statutory powers must remain within the governing legislation, consider mandatory statutory factors and use a procedurally lawful decision-making process.

Significance: Although not a smart-meter-specific case, it is relevant to Ofgem’s supervision of rollout licence conditions: deployment requirements and enforcement remain reviewable on ordinary public-law grounds.

Case Name/Citation: Lloyd v Google LLC [2021] UKSC 50

Facts: A representative claimant alleged unlawful tracking and use of millions of iPhone users’ personal data.

Legal Issue: Whether compensation could be recovered for data-protection breaches without proving material damage or distress for each individual.

Judgment: The Supreme Court allowed Google’s appeal and held that compensation under the applicable legislation required proof of individual damage.

Legal Principle/Ratio: Unlawful data processing and compensable damage are distinct questions; mass data claims cannot automatically bypass proof of individual loss.

Significance: Smart-meter data can reveal detailed consumption patterns. Suppliers and authorised users must therefore treat data governance, lawful processing, security and consent as core legal components of rollout compliance.

6. Conclusion

The UK smart-meter rollout is therefore a regulated infrastructure programme built on statutory powers, licence obligations, technical codes, DCC governance, consumer safeguards and data law. Compliance requires not only installing meters, but maintaining communications, meeting deployment duties, protecting consumers and processing consumption data lawfully.
