Understanding which machinery falls under Annex IV high-risk categories requiring Approved Body involvement, how to build a compliant technical file, and the UKCA vs CE question for industrial customers is essential for B2B market access.

No Approved Body required. **Note:** Manufacturer must maintain full technical file and risk assessment ### Safety components **Examples:** Guards, interlocks, two-hand controls, light curtains, enabling devices **Assessment route:** Safety components have their own conformity assessment requirements — treated as separate machinery **Note:** Must carry own UKCA marking and Declaration of Conformity ### Partly completed machinery **Examples:** Sub-assemblies, drive units, end-effectors intended for incorporation into other machinery **Assessment route:** No UKCA marking — Declaration of Incorporation (DoI) required instead **Note:** Final assembler takes responsibility for overall machinery compliance ## Essential Health and Safety Requirements (EHSRs) General principles: Machinery must be designed so it can be operated safely and without causing harm to persons, domestic animals, or property under reasonably foreseeable conditions. Control systems: Control systems must be designed to withstand intended operating stresses and external influences. Safety-related control systems must prevent hazardous situations at startup and on fault. Protection against mechanical hazards: Guards and protective devices must prevent access to danger zones. Fixed guards preferred; interlocked guards where access is required. Required characteristics of guards: Guards must be robust, difficult to bypass, not cause additional hazards, and not restrict operator vision of the process where possible. Ergonomics and operator interface: Operating positions must permit supervision of danger zones. Lighting, noise, vibration, temperature, and physical effort demands must be within acceptable limits. Maintenance: Machinery must be designed so maintenance can be carried out with machine stopped. Where this is not possible, protective measures must be in place for maintenance operations. ## Technical file: required contents 01General description of the machinery and intended use 02Overall drawing and drawings of control circuits 03Detailed drawings with notes and calculations for manufacturing and functional inspection 04Risk assessment documentation showing hazard identification, risk evaluation, and measures applied 05List of UK designated standards (and any other standards) applied 06Description of protective measures adopted to eliminate identified hazards 07Technical reports from tests carried out by the manufacturer or approved bodies 08Copy of UK Declaration of Conformity 09For series manufacture: internal measures to ensure conformity is maintained ## Learn this properly, not just for one product In-depth courses and books that teach the process — not a one-off answer you'll need to look up again next time.

No — for UKCA marking, you must use a UK Approved Body, not an EU Notified Body. UK Approved Bodies are listed on the UK government's approved bodies database. For machinery in Annex IV categories, the Approved Body must examine the technical file or carry out full quality assurance. If you already have CE marking with EU Notified Body involvement, you will need a separate UK Approved Body assessment for UKCA. ### Is CE marking still accepted for industrial machinery in Great Britain? For most machinery, CE marking continues to be accepted indefinitely in Great Britain. The UK government has confirmed CE marking recognition will continue for products covered by the Supply of Machinery (Safety) Regulations. However, if you need to use a UK Approved Body for third-party assessment (Annex IV machinery), you will need UKCA marking for those specific assessment routes. Always check the current OPSS guidance for the specific product category. ### What is the difference between machinery risk assessment for UKCA vs CE? The risk assessment methodology required under UK Machinery Regulations is technically identical to that required under the EU Machinery Directive: hazard identification, risk estimation, risk evaluation against the EHSRs, and risk reduction measures in order of priority (inherently safe design, safeguarding, user information). A risk assessment prepared for CE marking is generally acceptable for UKCA, as both reference the same EN ISO 12100 standard for risk assessment methodology. 🇬🇧 UK roadmap for machinery Every standard, document, and test that applies — free, no account required.
