A single non-compliant component can halt your production line, trigger costly product recalls, or expose your organization to regulatory penalties exceeding £5,000 per infringement. Yet procurement teams regularly approve purchase orders without verifying the three critical compliance certifications that protect UK businesses: RoHS restrictions on hazardous substances, REACH chemical safety registrations, and UKCA conformity marking.
At Cobra Electronics, our compliance verification processes have prevented hundreds of potentially non-compliant components from entering our clients’ supply chains. This guide explains exactly what procurement professionals must verify before issuing purchase orders—ensuring your component sourcing meets UK regulatory requirements.
The stakes couldn’t be higher. Post-Brexit UK regulations diverge from EU standards, creating new compliance obligations for component buyers. Understanding these requirements isn’t optional—it’s essential for legal operation, market access, and brand protection.
Understanding UK Electronics Compliance: The Three Essential Frameworks
UK component procurement operates under three interconnected regulatory frameworks. Each addresses different aspects of product safety, environmental protection, and market access.
RoHS: Restriction of Hazardous Substances
The Restriction of Hazardous Substances (RoHS) Directive limits specific hazardous materials in electrical and electronic equipment sold in the UK market. Originally implemented as EU legislation, the UK maintains RoHS requirements post-Brexit through domestic regulations.
RoHS Restricted Substances (Maximum Concentration Values):
- Lead (Pb) – 0.1% (1,000 ppm)
- Mercury (Hg) – 0.1% (1,000 ppm)
- Cadmium (Cd) – 0.01% (100 ppm)
- Hexavalent Chromium (Cr VI) – 0.1% (1,000 ppm)
- Polybrominated Biphenyls (PBB) – 0.1% (1,000 ppm)
- Polybrominated Diphenyl Ethers (PBDE) – 0.1% (1,000 ppm)
- Bis(2-Ethylhexyl) Phthalate (DEHP) – 0.1% (1,000 ppm)
- Butyl Benzyl Phthalate (BBP) – 0.1% (1,000 ppm)
- Dibutyl Phthalate (DBP) – 0.1% (1,000 ppm)
- Diisobutyl Phthalate (DIBP) – 0.1% (1,000 ppm)
Why RoHS Compliance Matters:
RoHS regulations protect human health and the environment by restricting toxic materials in electronics. For procurement teams, RoHS compliance verification prevents regulatory violations, enables market access, and demonstrates corporate environmental responsibility.
Components failing RoHS compliance cannot legally be sold in UK markets. Products containing non-compliant components face import seizures, market withdrawal requirements, and potential prosecution.
REACH: Registration, Evaluation, Authorization of Chemicals
REACH regulations manage chemical substances throughout their lifecycle, from manufacturing through disposal. While more complex than RoHS, REACH fundamentally ensures that businesses understand and control chemical risks in their products.
Key REACH Obligations for Component Buyers:
Substances of Very High Concern (SVHC)
The SVHC Candidate List (updated twice annually) identifies chemicals requiring special management. Currently containing over 230 substances, this list includes carcinogens, mutagens, reproductive toxins, and environmentally persistent chemicals.
If any SVHC exceeds 0.1% weight by weight in a component, suppliers must:
- Provide safety information to buyers
- Communicate safe use requirements
- Notify the European Chemicals Agency (ECHA) if supplying over one tonne annually
Authorization and Restriction Requirements
Some SVHC substances require explicit authorization for use. Others face outright restrictions. Procurement must verify that component suppliers comply with authorization requirements or confirm restricted substances aren’t present.
UK REACH vs. EU REACH
Post-Brexit, the UK operates an independent REACH scheme (UK REACH) with its own registration requirements. Components entering the UK market must comply with UK REACH, while those exported to the EU must meet EU REACH. This dual compliance requirement creates additional verification obligations for UK procurement teams.
UKCA: UK Conformity Assessed Marking
The UKCA (UK Conformity Assessed) marking replaced the CE marking for products placed on the UK market (England, Scotland, and Wales—Northern Ireland follows different rules due to the Protocol).
UKCA Marking Requirements for Electronic Components:
UKCA marking demonstrates that products comply with relevant UK regulations covering:
- Electromagnetic Compatibility (EMC)
- Electrical Equipment Safety
- Radio Equipment
- RoHS compliance
Critical UKCA Considerations:
Transition Period Completion
As of January 1, 2023, UKCA marking is mandatory for most products. The CE marking transition period has ended for most product categories, though specific rules apply to different sectors.
Northern Ireland Exception
Due to the Northern Ireland Protocol, products placed on the Northern Ireland market may continue using CE marking. Products moving between Great Britain and Northern Ireland require careful compliance assessment.
Manufacturer Responsibilities
UKCA marking places legal responsibility on manufacturers to ensure compliance. For component buyers, this means verifying that suppliers have completed appropriate conformity assessment procedures and maintain technical documentation.
Pre-PO Compliance Verification: Your Essential Checklist
Effective compliance verification occurs before purchase order approval, not after components arrive. This systematic approach prevents costly non-compliance discoveries during production or market surveillance.
Document Verification Requirements
1. RoHS Declaration of Conformity
Every component must include a RoHS Declaration of Conformity explicitly stating:
- Manufacturer details and contact information
- Component part number and description
- Declaration that the component complies with UK RoHS requirements
- Date of declaration
- Authorized signatory details
Red Flags: Generic declarations covering “all products,” missing part numbers, or declarations over 3 years old without reconfirmation require immediate supplier verification.
2. Material Composition Disclosure
Request full material disclosure documentation showing:
- All substances present above 0.1% concentration
- Specific confirmation that restricted substances remain below maximum concentration values
- Test methods and laboratory certifications (IEC 62321 is the recognized standard)
Cobra Electronics maintains verified material disclosures for all stocked components, eliminating procurement delays while ensuring compliance confidence.
3. REACH SVHC Declaration
Suppliers must explicitly declare whether components contain any SVHC substances above 0.1% threshold. This declaration should:
- Reference the current SVHC Candidate List date
- List any SVHC substances present with concentration ranges
- Provide safe use guidance for any SVHC substances identified
- Confirm compliance with authorization requirements if applicable
4. UKCA Technical File Evidence
While suppliers aren’t required to share complete technical files, buyers should verify:
- UKCA marking appears on products or packaging where required
- Supplier confirms completion of conformity assessment procedures
- UK address details for compliance queries (required post-Brexit)
- Declaration of conformity covering applicable UK regulations

Frequently Asked Questions About UK Component Compliance
Does every electronic component require RoHS compliance certification?
RoHS applies to electrical and electronic equipment (EEE) placed on the UK market. Most electronic components fall within scope. However, some applications have exemptions (e.g., certain military, aerospace, or medical applications). Procurement teams should verify whether exemptions apply to specific use cases. When in doubt, requiring RoHS compliance provides the safest approach.
How often should we reverify supplier compliance documentation?
Best practice suggests annual compliance reverification as minimum. Additionally, reverify when:
- SVHC Candidate Lists update (twice annually)
- Manufacturers notify component changes
- New regulatory requirements take effect
- Switching to new suppliers or component sources
- Regulatory agencies update testing standards or methodologies
What’s the difference between CE and UKCA marking?
CE marking demonstrates compliance with EU regulations, while UKCA marking demonstrates UK compliance. Post-Brexit, products for the UK market require UKCA marking (with some transitional arrangements). Products for the EU market need CE marking. Northern Ireland follows special rules allowing CE marking due to the Protocol. Many manufacturers maintain both certifications for market flexibility.
Can we accept supplier self-declarations, or must we require third-party testing?
UK regulations generally permit manufacturer self-declaration for RoHS and UKCA compliance. However, these declarations must be based on adequate testing and analysis. Procurement best practice involves:
- Requesting underlying test reports supporting declarations
- Verifying tests were conducted by accredited laboratories
- Evaluating supplier quality management systems
- Conducting periodic audits of supplier compliance programs
Self-declarations without supporting evidence create unnecessary compliance risk.
What happens if we discover non-compliant components already in production?
Immediate actions include:
- Halt production using affected components
- Quarantine remaining inventory and work-in-progress
- Notify customers if non-compliant products were shipped
- Contact suppliers to verify non-compliance and request corrective action
- Source compliant replacement components urgently
- Investigate root cause and implement preventive measures
- Consider whether regulatory notification is required
Time-sensitive situations benefit from working with suppliers like Cobra Electronics maintaining verified UK stock of compliant alternatives.
Are Arduino and Raspberry Pi development boards subject to these regulations?
Yes. Development boards are electronic equipment subject to RoHS, REACH, and UKCA requirements when placed on the UK market. Official Arduino and Raspberry Pi products include compliance certifications. When sourcing compatible or clone boards, verify compliance documentation carefully—cheaper alternatives sometimes cut corners on compliance verification.
How do we handle components going into products exported to both UK and EU markets?
Components for products sold in both UK and EU markets should comply with both UK REACH and EU REACH, along with both UKCA and CE marking requirements where applicable. This dual compliance requirement increases documentation complexity. Working with suppliers who maintain compliance with both regimes simplifies procurement. Some manufacturers maintain UK and EU-specific product variants; verify which variant you’re purchasing.
What resources can help us stay current with compliance changes?
Recommended resources include:
- UK Health and Safety Executive (HSE) for RoHS guidance
