The assessment provides a summary of the government's original position at the point the Bill was introduced, prior to the current government coming in, and notes the reasons for not opting for a later sunset date. 22 November 2022 Energy sector—Retained EU law reform—bonfire of laws or death by judicial review Munir Hassan, partner, Juliet Stradling, senior counsel, Phillip Ashley, partner, James Wright, associate, and Natasha Kenber, trainee solicitor, at CMS, discuss the Retained EU Law (Revocation and Reform) Bill and how it may impact the energy sector. 28 September 2022 Brexit Bulletin—agenda for third meeting of Specialised Committee on Energy published, LNB News 28/09/2022 33 The UK government has published the provisional draft agenda for the third meeting of the Specialised

A certification giving a property an efficiency'>energy efficiency rating from A (high) to G (low) by looking at various factors (eg age, type, construction, insulation, heating systems) to promote the improvement of the energy performance of buildings and identify ways to improve energy performance and reduce associated costs.

STOP PRESS: The Energy Performance of Buildings (Scotland) Regulations 2025, SSI 2025/417 (EPC Regs 2025) revoke and replace the Energy Performance of Buildings (Scotland) Regulations 2008, SSI 2008/309 (EPC Regs 2008), updating Scotland’s energy performance framework for all buildings. EPC Regs 2025, regs 11 and 12 are in force from 1 January 2026 enabling the approval of organisations and of accreditation schemes. However, the Scottish Government has announced (March 2026) that the provisions introducing the new-style EPC regime will not come into force on 31 October 2026 as originally planned. The current EPC regime under the EPC Regs 2008 remains in place pending a revised implementation timetable. See Reform of EPCs below. How do EPCs apply to commercial property in Scotland? This Practice Note looks at how the EPC Regs 2008, SSI 2008/309 (as amended) apply to commercial property in Scotland. The EPC Regs 2008 require: • an EPC to be produced on the sale, rent or construction of a building • an EPC to be accompanied by

Ireland—Property analysis: This article, written by Brian O’Rourke, partner (Real Estate), Deirdre Barrett, partner (Real Estate) and Deirdre Sheehan, partner (Real Estate) of Arthur Cox LLP, examines Ireland's initial transposition of Directive (EU) 2024/1275, the recast Energy Performance of Buildings Directive. It outlines reforms to the Building Energy Rating (BER) regime, including the introduction of a simplified BER scale and a zero-emission building (ZEB) category, explains the interaction with existing building regulations and considers the remaining measures to be transposed, including future ZEB standards and minimum energy performance requirements for existing buildings.

Environment analysis: The UK government has launched a consultation to reform the Energy Performance of Buildings (EPB) regime, a crucial step towards achieving the nation’s ambitious net-zero targets by 2050. This extensive consultation, which runs until 26 February 2025, seeks to gather input on several key areas of the EPB framework. Here, we delve into the background leading up to this consultation, the key areas being consulted on, and likely next steps. Written by Victoria Duxbury, Lead Knowledge Counsel—Real Estate, BCLP.

[means products or systems that use as little electricity, gas, or other forms of energy as possible. OR means the amount of energy saved following implementation of energy efficient measures or practices. OR means an amount of saved energy determined by measuring and/or estimating consumption before and after implementation of one or more energy efficiency improvement measures, while ensuring normalisation for external conditions that affect energy consumption. OR means the amount of energy saved per annum and expressed in kilowatt hours (kWh) and that result from the [measures specified in Schedule [X]].]

ESOS is an energy assessment and energy savings scheme. It is mandatory for organisations that meet the qualification criteria, ie large undertakings and their corporate groups. It derives from the Energy Efficiency Directive 2012/27/EU, art 8(4)–(6), which requires EU Member States to ensure that enterprises that are not small and medium enterprises (SMEs) are subject to an energy audit carried out at least every four years. For more information, see Practice Note: Energy Efficiency Directive 2012/27/EU—snapshot [Archived]. The requirements of the Energy Efficiency Directive, art 8(4)–(6) were implemented in the UK through the Energy Savings Opportunity Scheme Regulations 2014, SI 2014/1643 (ESOS Regulations). The ESOS Regulations were made on 24 June 2014 and came into force on 17 July 2014. The Energy Act 2023 has granted powers to make necessary changes to ESOS post-Brexit, and the Energy Savings Opportunity Scheme (Amendment) Regulations 2023, SI 2023/1182 have made changes in advance of the Phase 3 compliance deadline. Substantive changes have also been made by the Energy Savings Opportunity Scheme (Amendment) Regulations
