Ecodesign — Seasonal Space Heating Energy Efficiency (ηs) Requirements (GB) China's primary energy efficiency standard for air-source heat pumps used as room air conditioners or heating equipment is GB 21455-2019 (Minimum allowable values of energy efficiency and energy efficiency grades for room air conditioners), which sets minimum energy efficiency ratio (EER) and coefficient of performance (COP) at rated conditions, not seasonal metrics. For low-ambient heat pump water heaters, GB/T 25127-2020 (Low ambient temperature air source heat pump water heater for household and similar use) covers performance under low-temperature conditions. China does not use the ηs/SCOP seasonal metric framework; Chinese test conditions and metrics are not directly comparable to EN 14511 / EN 14825 results used for UK Ecodesign compliance.GB 21455-2019 — Minimum allowable values of energy efficiency and energy efficiency grades for room air conditioners (SAMR/SAC)

Energy Labelling — A+++ to G Scale for Space Heaters (GB) China has an energy labelling system under the China Energy Label (中国能效标识) scheme, administered by NDRC and SAMR. For room air conditioners, energy efficiency grades 1–5 under GB 21455-2019 are used (Grade 1 being most efficient). However, the Chinese A-to-G or A+++ scale does not exist; the Grade 1–5 system is not equivalent to the UK/EU A+++ to G label. Product energy labels in China use a different graphical format (horizontal bar with 1–5 grades). Chinese energy label documentation cannot substitute for UK energy labelling obligations under SI 2021/1095.GB 21455-2019 — Energy efficiency grades 1–5 for room air conditioners (basis for China Energy Label)
China Energy Label (中国能效标识) scheme — NDRC/SAMR administered		 The Energy Information Regulations 2021 (SI 2021/1095) is the GB-retained framework for energy labelling of energy-related products, including covered space-heating heat pumps. The legal obligation is to provide and display the correct energy label and product information under SI 2021/1095. EN 14825 is a voluntary harmonised/designated test standard commonly used to derive seasonal space-heating efficiency data for label-class calculation; it is not itself the mandatory legal obligation.The Energy Information Regulations 2021 (SI 2021/1095)

Electromagnetic Compatibility (EMC) — UK EMC Regulations 2016 (SI 2016/1091) China's EMC requirements for household appliances including heat pumps are primarily covered under GB 4343.1 (Electromagnetic disturbance characteristics for household appliances, electric tools, and similar apparatus — Part 1: Emission) and GB/T 4343.2 (immunity), which are technically based on the CISPR 14 series. For heat pumps and air conditioning equipment, GB/T 17626 series (IEC 61000-4 based) applies for immunity testing. EMC compliance is part of the CCC certification process. Chinese EMC test reports to GB 4343.1/4343.2 are not accepted as equivalent to EN 55014-1/55014-2 testing for UK EMC Regulations compliance, as the test conditions, limits, and certification pathways differ.GB 4343.1 — Electromagnetic disturbance characteristics — household appliances, electric tools — Emission (SAMR/SAC; based on CISPR 14-1)

Air-source heat pumps, as electrical apparatus containing motors and power electronics, must meet the essential EMC requirements for emissions and immunity. The EN 55014 and EN 61000 series are voluntary harmonised/designated standards that may be used to demonstrate presumption of conformity; the mandatory legal duty is compliance with SI 2016/1091, not use of the named EN standards.

F-Gas Regulation — Refrigerant Containment and Recovery (GB) China manages refrigerants primarily through the Ozone-Depleting Substances Regulations (国务院令第573号 — Regulations on the Administration of Ozone-Depleting Substances, 2010) and associated measures implementing the Kigali Amendment. China is a Party to the Montreal Protocol and its Kigali Amendment (ratified 2021), obligating HFC phasedown. Domestic refrigerant management requirements focus on production quotas and disposal rather than an equipment-level F-gas containment inspection regime comparable to the UK/EU system. Chinese heat pump manufacturers testing to GB 4706.32 or GB/T 25127 are not required to demonstrate F-gas containment compliance to the same leak-check frequency and record-keeping standards as the UK SI 2022/1013.Regulations on the Administration of Ozone-Depleting Substances (国务院令第573号, 2010) — China
Kigali Amendment to the Montreal Protocol — HFC phasedown obligations (China ratified 2021)		 The Fluorinated Greenhouse Gases Regulations 2022 (SI 2022/1013) is the primary UK retained and amended framework governing fluorinated greenhouse gases (F-gases) in Great Britain. For air-source heat pumps, mandatory legal obligations can include containment, leak-checking above specified charge thresholds, recovery before decommissioning by certified personnel, record keeping, and HFC quota arrangements for pre-charged equipment. Refrigerants commonly used in Chinese heat pumps include R32, R410A, and R290. R32 and R410A are subject to F-gas containment and recovery obligations. R290 is not an F-gas but introduces separate flammability risk controls under product safety, installation, and building requirements; EN 378 may be used as a voluntary technical standard where relevant, but it is not itself the mandatory legal obligation.The Fluorinated Greenhouse Gases Regulations 2022 (SI 2022/1013)
The Fluorinated Greenhouse Gases (Amendment) Regulations 2023 (SI 2023/1349) — further GB amendments		 Exporters of pre-charged heat pump units to the UK must ensure the UK importer or responsible person holds sufficient HFC quota under SI 2022/1013 before GB placement, and that technical documentation covers leak-check intervals and F-gas charge records required by UK law. Engineers installing, servicing, or decommissioning in-scope units in the UK must hold appropriate F-gas handling certification. Chinese domestic compliance with refrigerant production quotas does not satisfy UK F-gas import quota obligations. R290 heat pumps avoid HFC quota rules but still need flammability risk controls under applicable product safety, installation, and building rules; EN 378 is a voluntary technical standard that may support that assessment rather than a standalone mandatory legal requirement.[INFORMATIONAL] F-gas compliance under SI 2022/1013 is mandatory for in-scope pre-charged heat pumps placed on the GB market. Chinese domestic refrigerant compliance does not satisfy UK F-gas quota and containment obligations. EN 378 is not mandatory law; for R290 and other flammable refrigerants it is voluntary technical-standard evidence that may support the separate flammability risk assessment. legislation.gov.uk / King's Printer of Acts of Parliament2026-06-12 · unverified
UKCA Marking — Great Britain Market Placement Requirement (and CE Transitional Policy) China's equivalent mandatory market-access certification is the CCC (China Compulsory Certification) mark (中国强制认证). Heat pumps for household and similar use are listed in the CCC catalogue under household electrical appliances. CCC requires third-party testing by a CNCA-designated laboratory and factory inspection. CCC has no mutual recognition with UKCA and is not relevant to UK market access.China Compulsory Certification (CCC) — administered by CNCA under Regulations on Compulsory Product Certification
CCC catalogue — household electrical appliances including heat pumps for household use		 Conformity marking is required for GB market placement under the applicable UK product regulations for heat pumps, including SI 2016/1101, SI 2016/1091, SI 2021/745, and SI 2016/1105 where the pressure-equipment rules are in scope. UKCA is not the sole mandatory route for most covered goods in Great Britain: under UK Government guidance, CE marking continues to be recognised in GB where the relevant sector rules allow, while Northern Ireland uses CE marking and, where a UK body is involved, CE plus UKNI. The mandatory obligations are the applicable UK product-safety regulations, conformity assessment, technical documentation, declaration of conformity, responsible-person/importer duties, and the correct accepted marking for the market and date of placement.The Electrical Equipment (Safety) Regulations 2016 (SI 2016/1101)

Windsor Framework (Northern Ireland — CE marking continues)		 CCC is not recognised for UK market access. A UK Declaration of Conformity or accepted EU Declaration of Conformity, technical file, and correct conformity marking must be in place before GB placement. For GB, use UKCA or recognised CE where the sector rules allow under current GOV.UK guidance; for Northern Ireland, use CE and add UKNI where a UK conformity assessment body is used. Exporters must verify the current GOV.UK sector guidance at shipment because CE-recognition rules can change.[INFORMATIONAL] Conformity marking is required, but UKCA is not the sole mandatory mark for GB where UK Government CE-recognition policy allows recognised CE marking. Heat pumps still need the applicable UK/EU conformity documentation, technical file, responsible-person/importer arrangements, and accepted marking for GB or NI. CCC has no equivalence.

MCS Certification — Scheme-Conditional Requirement for Boiler Upgrade Scheme Grant Eligibility There is no direct Chinese equivalent to the MCS scheme-conditional certification system. China does not have an equivalent residential heat pump installation grant scheme with associated product certification requirements comparable to MCS. Chinese manufacturers seeking UK residential market access for heat pumps eligible for government grants must obtain MCS product certification independently of their existing Chinese certifications (CCC, GB/T 25127 testing, etc.). MCS certification requires EN 14511 performance data and a quality management framework that aligns with MCS audit requirements — Chinese CCC documentation does not satisfy MCS assessment criteria.No direct Chinese equivalent — CCC and GB/T 25127 are the closest domestic credentials but are not accepted by MCS
GB/T 25127-2020 — Low ambient temperature air source heat pump water heater (SAC) — CN performance reference		 MCS (Microgeneration Certification Scheme) certification is NOT a general import law requirement for air-source heat pumps entering the UK market. It is a scheme-conditional requirement: heat pump installations must be carried out by MCS-certified installers using MCS-certified products to be eligible for government grants under the Boiler Upgrade Scheme (BUS). The Boiler Upgrade Scheme provides grants (the amount may change — verify current figures at gov.uk/apply-boiler-upgrade-scheme) for replacing fossil fuel boilers with low-carbon heating systems including heat pumps. MCS product certification requires the heat pump to meet MCS 007 (Heat Pump Standard), which references EN 14511 performance testing, minimum COP and SCOP values, and quality management requirements. The MCS Certified Products Directory lists approved products. Without MCS product certification, the heat pump can still be legally sold and installed in the UK, but the installer cannot claim BUS grants for that installation. MCS is administered by MCS Charitable Foundation and the scheme rules are set independently of statutory product regulations.MCS 007 — Heat Pump Standard (MCS Charitable Foundation) — product certification requirement for BUS eligibility
Boiler Upgrade Scheme (BUS) — administered by Ofgem under the Energy Act 2013 (UK)
EN 14511:2018 — Performance testing referenced by MCS 007		 MCS certification is not required to legally sell or import heat pumps into the UK. However, without MCS product certification, residential end-users cannot claim Boiler Upgrade Scheme grants for installations using that product, severely limiting commercial appeal in the residential retrofit market (which is the primary UK heat pump market segment). Chinese manufacturers targeting the UK residential market should budget for MCS 007 assessment, EN 14511 testing (if not already done for Ecodesign compliance), and ongoing MCS audit obligations. MCS certification is a commercial necessity for most UK residential heat pump sales even though it is not a statutory import requirement.[INFORMATIONAL] MCS certification is scheme-conditional (required for Boiler Upgrade Scheme grant eligibility) but is NOT a statutory import or product safety law requirement. Heat pumps can be legally sold and installed in the UK without MCS certification, but this eliminates BUS grant eligibility for residential installations, which is a significant commercial barrier in the UK residential market. Chinese manufacturers targeting residential sales should treat MCS as a commercial necessity. UK Government / Ofgem2026-06-12 · unverified
Boiler Upgrade Scheme (BUS) — Grant Eligibility Conditions China has various heat pump subsidy programmes at national and provincial level under energy conservation and rural heating policies, but there is no direct equivalent to the BUS scheme-conditional MCS certification requirement. Chinese subsidy programmes are typically administered through provincial governments and linked to approved product catalogues or energy efficiency grades under GB 21455, not a third-party certification scheme comparable to MCS.No direct Chinese equivalent — Chinese heat pump subsidies are administered through provincial government approved product catalogues, not MCS-equivalent certification The Boiler Upgrade Scheme (BUS) is a UK government grant programme administered by Ofgem that provides financial incentives for replacing fossil fuel heating systems with low-carbon alternatives including air-source heat pumps in residential and small non-domestic properties. Eligibility conditions include: (1) the property must have a valid Energy Performance Certificate (EPC) with no outstanding loft or cavity wall insulation recommendations; (2) the heat pump product must be MCS-certified (see hpuk-market-access-02); (3) the installation must be carried out by an MCS-certified installer; (4) the scheme grant amount is subject to government review and may change (verify current figures at gov.uk/apply-boiler-upgrade-scheme). The BUS is a demand-side financial mechanism, not a product regulation.

MCS 007 — Heat Pump Standard (product eligibility prerequisite)		 The BUS and MCS requirements are a commercial barrier, not a statutory import requirement. Chinese manufacturers without MCS product certification cannot have their products installed under the BUS grant programme, which is the primary demand-driver for the UK residential heat pump market. Obtaining MCS certification requires: EN 14511 performance testing, a quality management system audit, and ongoing compliance with MCS scheme rules and product re-testing intervals. This is a scheme-conditional gap — it does not affect legal importation but directly affects commercial viability in the UK residential sector.[INFORMATIONAL] The Boiler Upgrade Scheme is a UK government grant programme, not a product regulation. MCS certification is the prerequisite for BUS eligibility. Neither BUS nor MCS is a statutory import requirement, but both are commercially essential for the UK residential heat pump market.

Pressure Equipment Safety — Refrigerant Circuit (UK PER 2016) China's pressure equipment framework is administered by the State Administration for Market Regulation (SAMR) under the Special Equipment Safety Law (特种设备安全法, 2013) and the Regulations on Safety Supervision of Special Equipment (特种设备安全监察条例). Pressure vessels in heat pump refrigerant circuits may be classified as special equipment (特种设备) depending on design pressure and volume. Manufacturers must hold a Special Equipment Manufacturing Licence (特种设备制造许可证) issued by SAMR for in-scope equipment. The Chinese pressure vessel standard GB 150 series and the refrigerating system standard GB 9237 (Safety requirements for refrigerating systems) are the primary technical references. Compliance with the Chinese special equipment framework does not satisfy UK PER 2016 conformity assessment requirements; the classification categories, conformity assessment routes, and approval body systems are different.Special Equipment Safety Law (特种设备安全法, 2013) — China

Product Safety — EN 60335-2-40 Household Heat Pumps (GB) China's primary safety standard for household heat pumps is GB 4706.32 (Safety of household and similar electrical appliances — Particular requirements for heat pumps, air-conditioners and dehumidifiers), which is technically based on IEC 60335-2-40 with national deviations. Products must obtain CCC (China Compulsory Certification) for domestic market sale under the low-voltage electrical apparatus catalogue. CCC testing is conducted by CNCA-designated laboratories. While the GB 4706.32 standard shares a common IEC ancestor with EN 60335-2-40, national deviations, test conditions, and the certification pathway (third-party CCC vs. UK self-declaration with UKCA) are different. GB 4706.32 / CCC certification is not accepted as a substitute for EN 60335-2-40 testing under UK product safety regulations.GB 4706.32 — Safety of household and similar electrical appliances — Particular requirements for heat pumps, air-conditioners and dehumidifiers (SAMR/SAC; technically based on IEC 60335-2-40 with national deviations)
