EMC & RoHS Compliance China's EMC requirements for BESS draw on the GB/T 17626 series (EMC immunity testing, technically equivalent to IEC 61000-4 series) and GB 9254 (EMC emissions limits for information technology equipment). For power electronics and inverters within BESS, GB/T 14549 covers harmonic limits for grid-connected equipment. China RoHS is governed by the Administrative Measures on the Restriction of the Use of Hazardous Substances in Electrical and Electronic Products (2016 revision), with limit values set in GB/T 26572-2011 — similar in structure to EU/UK RoHS but implemented through a self-declaration and product filing regime managed by MIIT rather than a mandatory CAB conformity assessment.GB/T 17626 series — 电磁兼容 试验和测量技术 (EMC immunity testing — technically aligned to IEC 61000-4 series)
GB 9254-2008 — 信息技术设备的无线电骚扰限值和测量方法 (EMC emissions for IT equipment)
GB/T 26572-2011 — 电子电气产品中限用物质的限量要求 (Restriction of hazardous substances limit values — China RoHS)		 The Electromagnetic Compatibility Regulations 2016 (SI 2016/1091) require that BESS placed on the Great Britain market does not cause harmful electromagnetic interference and has adequate immunity to electromagnetic disturbance. Applicable harmonised standards include BS EN IEC 61000-6-2:2019 (Generic immunity standard for industrial environments) and BS EN IEC 61000-6-4:2019 (Generic emissions standard for industrial environments). A UK Declaration of Conformity citing UK-applicable BS EN standards and a UK Technical File must be prepared. RoHS: The Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Regulations 2012 (SI 2012/3032, UK RoHS) restrict the use of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE) in electrical and electronic equipment. Whether a BESS falls within the scope of UK RoHS depends on its classification — industrial monitoring and control equipment exemptions may apply. Manufacturers should seek legal advice on RoHS classification before placing product on the market.SI 2016/1091 — Electromagnetic Compatibility Regulations 2016
SI 2012/3032 — The Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Regulations 2012 (UK RoHS)
BS EN IEC 61000-6-2:2019 — Electromagnetic compatibility — Generic immunity standard for industrial environments
BS EN IEC 61000-6-4:2019 — Electromagnetic compatibility — Generic emissions standard for industrial environments		 The GB/T 17626 EMC immunity test series is technically close to IEC 61000-4 (both share the same IEC source), so Chinese EMC immunity test data may be technically reusable if the tests were conducted by a UKAS-accredited or ILAC-recognised laboratory to equivalent test levels and configurations. However, UK EMC compliance requires a UK Declaration of Conformity citing UK-applicable standards (BS EN IEC prefix) and a UK Technical File regardless of whether underlying test data is reused. A separate UK DoC must be signed by the UK Responsible Person. Chinese EMC test reports issued under GB standards alone are not sufficient. For RoHS: China RoHS self-declaration does not automatically satisfy UK RoHS (SI 2012/3032) — a separate UK Technical File and RoHS declaration are required, and the RoHS classification scope question (particularly whether BESS qualifies for industrial monitoring and control equipment exemption) must be assessed under UK law.[INFORMATIONAL] A separate UK Declaration of Conformity citing BS EN IEC standards and a UK Technical File are required regardless of any existing Chinese EMC certification. Chinese EMC test data from UKAS/ILAC-accredited labs may potentially be reused within a new UK conformity assessment — verify with a UK technical expert. Chinese RoHS self-declaration does not satisfy UK RoHS; separate UK RoHS assessment and declaration are required. UK Office of Product Safety and Standards (OPSS)2026-06-12 · unverified
Fire Safety & Electrical Installation (BS 7671 / Approved Document B) In China, BESS installation is governed by GB/T 51048-2025 (Design Standard for Electrochemical Energy Storage Stations, effective April 1, 2026, superseding GB 51048-2014) at the design level. Fire protection for industrial buildings follows GB 50016-2014 (2018 revised edition, Code for Fire Protection Design of Buildings). The BMS fire-safety linkage requirements are addressed in GB/T 42288-2022 (Safety Code for Electrochemical Energy Storage Stations). Electrical installation practice follows GB 50054-2011 (Code for Design of Low Voltage Electrical Installations) and related standards.GB/T 51048-2025 — 电化学储能电站设计标准 (Design Standard for Electrochemical Energy Storage Stations; effective April 1, 2026)

GB 50054-2011 — 低压配电设计规范 (Code for Design of Low Voltage Electrical Installations)		 Electrical installation of BESS in the UK must comply with BS 7671:2018+A2:2022 (Requirements for Electrical Installations — IET Wiring Regulations, 18th Edition), which is the standard referenced by the Building Regulations 2010 for fixed electrical installation. Fire safety for buildings where BESS is installed is governed by the Building Regulations 2010 Approved Document B (Fire Safety). HSE has published specific guidance on battery storage safety risks. For standalone or outdoor BESS installations, planning permission under the Town and Country Planning Act 1990 may be required; permitted development rights vary by system size, location, and land classification. Pre-application consultation with the local planning authority and the relevant Fire and Rescue Service is strongly recommended for large systems.BS 7671:2018+A2:2022 — Requirements for Electrical Installations (IET Wiring Regulations, 18th Edition)
Building Regulations 2010 Approved Document B — Fire Safety
HSE Battery Storage Safety Guidance — hse.gov.uk/electricity/battery-storage.htm
Town and Country Planning Act 1990 — planning permission requirements		 UK BS 7671 and Chinese GB 50054 share IEC roots but diverge significantly on earthing arrangements (TN-C-S is the predominant UK domestic/commercial arrangement; TT is more common in Chinese rural installations), discrimination and selectivity rules, arc-fault protection requirements, and specific BESS compartment ventilation and thermal management provisions. Chinese design code compliance (GB/T 51048) does not transfer to BS 7671 — a UK-qualified electrician (registered with NICEIC or ECA) must design and certify the installation to BS 7671. Approved Document B fire compartmentation requirements for BESS may differ substantially from GB 50016 provisions on room sizing, separation distances, and suppression system trigger criteria.[INFORMATIONAL] A separate UK electrical installation design to BS 7671 is required — Chinese design code compliance (GB/T 51048) does not satisfy BS 7671. A UK-qualified and registered electrician must design, install, and certify the system. Fire compartmentation must be assessed against Approved Document B, which may impose different separation and suppression requirements than the Chinese equivalents.

Grid Connection — ENA EREC G99 / G98 In China, grid connection of electrochemical energy storage systems is governed by GB/T 36558-2022 (Technical Requirements for Grid-Connection of Electrochemical Energy Storage Systems) and NB/T 42129-2017 (Technical Requirements for Grid-Connected Inverters for Electrochemical Energy Storage Systems). Grid connection approval is managed by the provincial grid company (State Grid or Southern Grid) under NDRC and NEA regulations for new energy storage. The approval process involves a grid impact study, protection relay coordination with the grid company, and commissioning sign-off by the grid company's technical staff.GB/T 36558-2022 — 电化学储能系统接入电网技术规定 (Technical Requirements for Grid-Connection of Electrochemical Energy Storage Systems)
NB/T 42129-2017 — 电化学储能系统并网逆变器技术规范 (Technical Requirements for Grid-Connected Inverters for Electrochemical Energy Storage Systems)
NDRC / NEA — Measures for the Administration of New Energy Storage (2022)		 Grid connection of BESS in Great Britain that generates or stores more than 3.68 kW per phase (or more than 16 A per phase) requires compliance with ENA Engineering Recommendation EREC G99 Issue 1 (current amendment). Smaller systems at or below 3.68 kW per phase use ENA EREC G98. The G99 process requires: (1) a pre-application notification to the Distribution Network Operator (DNO) or Independent Distribution Network Operator (IDNO); (2) protection relay settings assessed and agreed with the DNO to G99 Schedule 1–3 requirements (depending on system type and capacity); (3) type testing or individual technical assessment approved by the DNO/IDNO; (4) commissioning by a competent person and DNO witness or acceptance testing. For grid-scale BESS above 1 MW that connect at transmission level or provide ancillary services: the National Grid ESO Grid Code and the Balancing and Settlement Code (BSC) obligations also apply, and a separate Connection and Use of System Agreement (CUSC) is required.ENA EREC G99 Issue 1 (current amendment) — Requirements for the Connection of Generation Equipment in Parallel with Public Distribution Networks
ENA EREC G98 Issue 1 (current amendment) — Requirements for Micro-generators Connected in Parallel with Public Low-Voltage Distribution Networks
National Grid ESO Grid Code — nationalgrideso.com/industry-information/codes/grid-code
Balancing and Settlement Code (BSC) — elexon.co.uk		 GB/T 36558 and ENA G99 differ substantially in several technical areas: frequency response operational range (GB/T 36558: 49.5–50.2 Hz normal operation; G99: 47–52 Hz operational range with defined Rate of Change of Frequency (ROCOF) ride-through), voltage ride-through curve shapes and hold times, reactive power control modes and capability requirements, and protection relay setting methodologies. G99 type-test approval is UK-specific — a product must be type-tested or individually assessed to G99 requirements by a laboratory or process acceptable to the relevant DNO. Chinese GB/T 36558 compliance test reports are not recognised by UK DNOs for G99 purposes. The DNO pre-application process, protection setting agreement, and commissioning witness tests are administrative steps with no Chinese equivalent.[INFORMATIONAL] G99 type testing and DNO pre-application approval are mandatory for grid-connected BESS above 3.68 kW per phase in Great Britain. GB/T 36558 compliance does not satisfy G99 — separate UK-specific type testing or individual technical assessment is required.

UKCA Marking, UK Responsible Person & Electrical Equipment (Safety) Regs 2016 — Market-Access Route In China, the primary mandatory market-access route for BESS is compliance with GB 36276-2023 (Safety Requirements for Lithium-Ion Batteries for Electrical Energy Storage). China Compulsory Certification (CCC, 3C) may apply to certain sub-categories of BESS depending on the applicable CCC catalogue — manufacturers should confirm whether their specific BESS configuration falls within a CCC-listed category with CNCA or an approved certification body, as the CCC catalogue for energy storage is periodically updated. Chinese manufacturers obtain a CCC certificate and affix the CCC mark; they can self-certify for non-CCC GB standards through factory inspection and type testing at CNAS-accredited laboratories. There is no equivalent to the UK Responsible Person concept in the Chinese system — the manufacturer itself bears the certification and market-access obligations domestically.GB 36276-2023 — 电力储能用锂离子蓄电池安全要求 (Safety requirements for lithium-ion batteries for electrical energy storage)
CCC (China Compulsory Certification) — CNCA catalogue-dependent; confirm applicability for BESS sub-category
GB/T 36276-2018 (superseded by GB 36276-2023) — earlier edition for reference only		 To place a BESS on the Great Britain market, a manufacturer must follow the conformity route under the Electrical Equipment (Safety) Regulations 2016 (SI 2016/1101) and, where applicable, the Electromagnetic Compatibility Regulations 2016 (SI 2016/1091). The market-access route has four structural elements: (1) Conformity assessment — demonstrate conformity with the relevant designated standard (principally BS EN IEC 62619:2022 and BS EN IEC 62933-5-1:2019) through a UK Conformity Assessed Body (UK CAB) where third-party assessment is required, or by the manufacturer's own declaration where self-declaration is permitted; (2) UK Declaration of Conformity (UKDOC) — a signed document listing the product, applicable standards, and the responsible person; (3) UKCA marking — the mark must appear on the product or, where impracticable, on its packaging or in accompanying documentation; it must not be affixed before all conformity obligations are met; and (4) UK Responsible Person — a manufacturer established outside the UK (including a Chinese manufacturer) must appoint a UK-based Responsible Person (natural or legal person established in the United Kingdom) who holds the Technical File, signs the UKDOC, and ensures the product conforms to applicable requirements before it is placed on the market. CE marking is currently accepted in Great Britain under the ongoing OPSS transition; however, this transition has been extended multiple times and its end date is subject to change — always verify the current policy at gov.uk/guidance/using-the-ukca-marking before relying on CE for Great Britain. Northern Ireland continues to require CE marking (and the UKNI mark for UK CAB-assessed products placed on the NI market) under the Windsor Framework.SI 2016/1101 — Electrical Equipment (Safety) Regulations 2016

OPSS UKCA marking guidance — gov.uk/guidance/using-the-ukca-marking
Windsor Framework — Northern Ireland CE/UKNI marking obligations		 Four structural gaps exist between the Chinese and UK market-access regimes: (1) Responsible Person — China has no equivalent requirement; a Chinese manufacturer exporting to Great Britain must appoint a UK-established Responsible Person before the product can legally be placed on the market. This person must hold the Technical File, sign the UKDOC, and be identifiable on the product or its documentation. (2) Conformity assessment route — CCC certificates and Chinese GB test reports are not recognised by UK CABs as equivalent to BS EN IEC 62619/62933 assessments; a separate UK-applicable conformity assessment is required. (3) CE/UKCA transition — CE marking is currently accepted in Great Britain under OPSS transition policy, but this is a temporary arrangement with an uncertain end date; a UKCA route should be planned. (4) Northern Ireland divergence — products destined for Northern Ireland must meet CE marking requirements (and UKNI mark if assessed by a UK CAB); the two parts of the UK are subject to different conformity marking regimes under the Windsor Framework, which adds administrative complexity for a single UK-wide distribution strategy.[INFORMATIONAL] A Chinese manufacturer cannot legally place a BESS on the Great Britain market without (a) appointing a UK-established Responsible Person, (b) completing a UK-applicable conformity assessment to BS EN IEC 62619/62933, (c) signing a UK Declaration of Conformity, and (d) affixing the UKCA mark (or currently-accepted CE mark — verify the OPSS transition deadline before relying on CE). Chinese CCC certificates and GB test reports alone do not satisfy the UK market-access requirements. Products destined for both GB and Northern Ireland face a split-regime compliance obligation under the Windsor Framework.

UKCA Safety Certification (BS EN IEC 62619 / 62933) China requires electrochemical BESS to comply with GB 36276-2023 (Safety Requirements for Lithium-Ion Batteries for Electrical Energy Storage), which covers similar electrochemical safety requirements at the cell and module level. GB 38031-2020 covers cell-level safety (originally for EV traction batteries but referenced for lithium cells in other applications). CCC (China Compulsory Certification) is not directly applicable to utility-scale BESS in all sub-categories — confirm applicable catalogue scope with the certification body. Chinese GB test reports from CNAS-accredited laboratories cover substantially similar electrochemical hazard scenarios as BS EN IEC 62619/62933 but are assessed to different test protocols, temperature ranges, and state-of-charge limits.GB 36276-2023 — 电力储能用锂离子蓄电池安全要求 (Safety requirements for lithium-ion batteries for electrical energy storage)
GB 38031-2020 — 电动汽车用动力蓄电池安全要求 (Safety requirements for traction battery — EV; cell-level safety reference)		 UKCA marking is mandatory under the Electrical Equipment (Safety) Regulations 2016 (SI 2016/1101) and the Electromagnetic Compatibility Regulations 2016 (SI 2016/1091) for BESS placed on the Great Britain market. The product must comply with BS EN IEC 62619:2022 (Safety requirements for secondary lithium cells and batteries for use in stationary applications) and BS EN IEC 62933-5-1:2019 (Safety requirements for grid-integrated electrical energy storage systems). Conformity assessment must be performed by a UK Conformity Assessment Body (UK CAB). CE marking is still accepted in Great Britain under the current OPSS transition policy; however, this transition period has been extended multiple times and may end — manufacturers should verify the current deadline at gov.uk/guidance/using-the-ukca-marking before relying on CE acceptance.SI 2016/1101 — Electrical Equipment (Safety) Regulations 2016

OPSS UKCA marking guidance — gov.uk/guidance/using-the-ukca-marking		 GB 36276-2023 aligns in scope with BS EN IEC 62619/62933 on electrochemical safety but test protocols, temperature ranges, and SOC limits differ. Chinese GB test reports are generally NOT accepted by UK CABs as equivalent to BS EN IEC 62619/62933 testing — independent UK-applicable testing is required. A structural administrative gap exists: the UKCA regime requires a UK-registered Responsible Person (importer or UK Authorised Representative) to hold the Technical File, sign the UK Declaration of Conformity, and affix the UKCA mark. A Chinese manufacturer without a UK legal entity cannot self-certify for UKCA and must appoint such a person before placing product on the Great Britain market.[INFORMATIONAL] A BESS product certified only to Chinese GB standards cannot be legally placed on the Great Britain market without UKCA marking (or currently-accepted CE marking under OPSS transition). GB test reports alone are insufficient — UK CAB testing and a UK Responsible Person appointment are required.

Transport of Lithium Batteries by Road — UN 38.3 + ADR / GB CDG Regs China requires UN 38.3 testing as a prerequisite for the transport of lithium batteries — this is a globally harmonised requirement and the same test standard applies. The domestic road-transport regime for dangerous goods is governed by the Regulations for the Road Transportation of Dangerous Goods (道路危险货物运输管理规定, MOTC Order No. 37, 2016 revision) and the GB classification and packaging standards GB 12268 (List of Dangerous Goods) and GB/T 15258 (Safety Data Sheet format). For BESS specifically, GB 36276-2023 includes cell-level transport provisions. Chinese transport documents (危险货物运单, DG waybill) are not valid for UK/ADR movements — UK-format dangerous goods notes and English-language safety data sheets (SDS) are required.UN 38.3 — same globally harmonised test standard as UK/international

GB 36276-2023 — cell-level transport provisions for BESS		 Lithium-ion batteries and BESS shipped to or within Great Britain by road must comply with two overlapping regimes. First, UN 38.3 testing (UN Manual of Tests and Criteria, Part III, Section 38.3) is mandatory before any lithium battery or cell is transported internationally or domestically — this includes electrical, mechanical, thermal, short-circuit, overcharge/forced-discharge, and altitude simulation tests. Test reports must be available for inspection. Second, road carriage of BESS units that contain lithium batteries above the small quantity thresholds is governed in Great Britain by the Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009 (SI 2009/1348, as amended — the 'GB CDG Regs'), which transpose ADR (European Agreement concerning the International Carriage of Dangerous Goods by Road) into GB law. BESS modules are classified under UN 3480 (lithium-ion batteries, not installed) or UN 3481 (lithium-ion batteries contained in / packed with equipment). Packing instructions P903 / LP904 apply. A Dangerous Goods Note (DGN) in English, emergency contact details, and driver/handler training to ADR 1.3/8.2 are required. Northern Ireland follows the same ADR regime under the Windsor Framework.UN Manual of Tests and Criteria, Part III, Section 38.3 — UN 38.3 lithium battery test

UN 3480 — Lithium-ion batteries (standalone); UN 3481 — Lithium-ion batteries in or packed with equipment
Packing Instruction P903 / LP904 — ADR packaging requirements for large lithium battery cells and modules		 The UN 38.3 test itself is the same standard globally — a valid UN 38.3 report from a CNAS-accredited Chinese laboratory is generally accepted for international transport including UK import. However, there are material administrative gaps: (1) Chinese road transport documents (危险货物运单) are not valid for road carriage within Great Britain — GB CDG Regs-compliant dangerous goods notes (DGN) in English are required. (2) Safety Data Sheets must be in English and follow UK/GHS CLP format (GB/T 15258 format is structurally different). (3) Drivers and handlers must hold ADR-applicable training certificates (ADR 1.3 awareness and, for drivers carrying above threshold quantities in tank vehicles, ADR 8.2 certificates) — Chinese MOTC dangerous-goods driver qualifications are not directly recognised. (4) Vehicle and packaging marking and labelling requirements under ADR differ from Chinese GB marking rules. (5) For very large BESS (heavy over-dimension loads), a STGO (Special Types General Order) abnormal load movement permit may be required under the Road Vehicles (Authorisation of Special Types) (General) Order 2003.[INFORMATIONAL] A valid UN 38.3 test report from a CNAS-accredited Chinese laboratory is generally portable for international and UK import purposes. However, Chinese road transport documents are not valid for in-GB road movements — English-language ADR-compliant dangerous goods notes, UK/GHS-format SDS, and ADR-trained drivers/handlers are required. Verify the current ADR edition incorporated into GB CDG Regs and confirm packing instruction applicability (P903/LP904) with the logistics provider before first shipment.
