Smart Energy Code meaning

Published by a LexisNexis Energy expert
What does Smart Energy Code mean?
Smart Energy Code (SEC) The industry multi‑party contract that governs the end‑to‑end smart metering arrangements in Great Britain, including use of the Data Communications Company (DCC) services. In practice, it sets the rights and obligations of energy suppliers, electricity distribution network operators, gas transporters and other DCC users and service providers. The SEC is not created by primary legislation but is designated and maintained under gas and electricity licence conditions overseen by Ofgem and the Secretary of State; its defined terms sit in the SEC and relevant licences. Key legal features include mandatory accession for GB suppliers and relevant network operators; governance by the SEC Panel; SEC Subsidiary Documents; security, data access and privacy controls; device enrolment and technical specifications; change control and performance assurance; and procedures for market entry, user access and incident management. Compliance is typically a licence obligation and is material in regulatory compliance, procurement and outsourcing, data access arrangements, diligence and transaction drafting. Jurisdiction: applies in Great Britain (England & Wales and Scotland). Northern Ireland and Ireland operate separate smart metering frameworks and do not use the SEC.

It will concentrate on complaints from domestic energy suppliers, small enterprise complaints against non-domestic suppliers, and heat network complaints. Electricity and gas networks and third-party intermediaries will instead be consulted on separately. The plans include shortening the escalation period for complaints from eight to four weeks, allowing automatic compensation where EO decisions are not put into effect promptly, and granting the EO a statutory designation. DESNZ has also stated that Ofgem will regulate third‑party intermediaries, including energy brokers and price comparison sites, which have previously operated...

EU energy cybersecurity and critical infrastructure: CER, NIS 2, electricity network code, forthcoming gas/hydrogen codes and Cyber Resilience Act—scope, obligations and timelines

Protection of critical infrastructure and cybersecurity—EU strategy In October 2016, the European Parliament’s Committee on Industry, Research and Energy (ITRE) issued a Cybersecurity Strategy for the Energy Sector. The paper reviewed prevailing policies and legislation, and considered routes for developing energy‑specific cyber security solutions and protective practices. It found that the continued rollout of smart energy systems, coupled with growing interconnection and interdependence across Member State borders, has produced rapid expansion of networked intelligence throughout energy grids and into consumers’ premises via smart devices. This enlarged attack surface, together with the fact that the energy system is inherently linked to every other critical infrastructure network, renders the sector especially susceptible to cyber attacks. That exposure has only grown since the 2016 strategy was released. On 16 December 2020, the European Commission and the High Representative of the Union for Foreign Affairs and Security Policy presented a new EU Cybersecurity Strategy. The 2020 plan encompasses the security of essential EU services (for example energy grids, railways and hospitals) and also...

Great Britain Retail Energy Code (REC): legal basis, governance and consolidation; Central Switching Service, key provisions and recent regulatory developments

What is the Retail Energy Code (REC)? The Retail Energy Code (REC) sets the framework for the retail elements of the gas and electricity markets in Great Britain (GB). It supports Ofgem’s Switching Programme and brings together, aligns and streamlines a range of retail obligations that were previously spread across different codes. For more on GB energy industry codes, see Practice Note: Industry Bodies and Codes—Great Britain electricity and gas market. The Switching Programme seeks to enhance customers’ experience of changing gas or electricity supplier, especially by enabling rapid switching. This accelerated switching model is delivered through the Central Switching Service (CSS), which became operational in July 2022 and is run by the CSS Provider under the REC. Under its smart metering communications licences, the Data Communications Company (DCC) must procure and provide the CSS and is, accordingly, the designated CSS Provider under the REC. For further detail on developments to date regarding Ofgem’s Switching Programme, see Practice Note: Great Britain energy market—policy and policy implementation tracker...

Great Britain smart metering: regulatory framework, DCC/SEC governance, roll-out obligations, non-domestic options, and MAP–supplier contracting (churn, asset tracking and risk protections)

What is smart metering? For an introduction to smart meters, see also Practice Note: What is a smart meter? In Great Britain, licensed electricity and gas suppliers are required under their supply licences to take all reasonable steps to roll out smart meters to domestic and small business customers. The programme is expected to lower customers’ energy bills, boost energy efficiency, and make it simpler to switch energy supplier. The UK government views smart metering as a crucial instrument for a low‑carbon economy, reaching net zero emissions by 2050, and realising ambitions for an affordable, secure and sustainable energy supply chain. The smart meter roll‑out has been extended on several occasions since the Electricity Act 1989 and Gas Act 1986 were amended to place duties on licensed suppliers to complete it. There have also been multiple reviews and publications on progress, including National Audit Office reports such as Rolling out smart meters (November 2018) and Update on the rollout of smart meters (June 2023). In August 2025, DESNZ...
