Since the UK formally left the European Union, the UKCA (UK Conformity Assessed) marking has become the primary conformity mark for products placed on the Great Britain market. For manufacturers and importers of electrical accessories such as switches and sockets, understanding the UKCA marking process is critical to ensuring market access. This article provides a comprehensive guide to the documentation and testing requirements for UKCA marking of switches and sockets, with a focus on BS 1363 standards.
What is UKCA Marking?
UKCA marking indicates that a product meets the applicable UK statutory requirements for safety, health, and environmental protection. For switches and sockets, the relevant legislation includes the Electrical Equipment (Safety) Regulations 2016 and the Plugs and Sockets etc. (Safety) Regulations 1994. The UKCA marking applies to products placed on the market in Great Britain (England, Wales, and Scotland). Northern Ireland continues to follow EU rules under the Northern Ireland Protocol.
Key Standards for Switches and Sockets Under UKCA
The primary standards that apply to switches and sockets under UKCA are:
- BS 1363-1: 13A plugs and socket-outlets
- BS 1363-2: 13A switched and unswitched socket-outlets
- BS 1363-3: Adaptors for 13A plugs and socket-outlets
- BS EN 60669-1: Switches for household and similar fixed electrical installations
- BS EN 60669-2-1: Particular requirements for electronic switches
These standards define requirements for dimensions, safety, electrical performance, and testing. For example, BS 1363-2 specifies that socket-outlets must have shutters to prevent the insertion of a single-pole plug, and must pass temperature rise tests at rated current.
Documentation Required for UKCA Compliance
To affix the UKCA mark, manufacturers must compile a technical file that demonstrates compliance. The required documentation includes:
- A declaration of conformity (DoC) stating that the product meets applicable UK regulations
- Detailed design and manufacturing drawings
- A list of the standards applied (e.g., BS 1363-2, BS EN 60669-1)
- Test reports from an accredited laboratory (UKAS-accredited or equivalent)
- Risk assessment documentation
- Instructions for safe installation, use, and maintenance (in English)
MORDIO supplies wall switches and sockets for British, European, and American-style markets and supports OEM/ODM discussions. Buyers should confirm the exact product specification, applicable certification, test documentation, MOQ, and lead time for each project with the MORDIO team before ordering.
Testing Requirements for UKCA Marking
Testing is a core part of UKCA certification. Products must be tested against the relevant standards by an approved body. For switches and sockets, typical tests include:
- Electrical strength and insulation resistance tests
- Temperature rise test under full load
- Mechanical endurance test (e.g., 10,000 cycles for switches)
- Resistance to heat and fire (glow-wire test at 650°C or 850°C)
- Protection against electric shock (shutter operation, clearance and creepage distances)
- Verification of dimensions and gauging for plug-socket compatibility
For products intended for outdoor or damp locations, additional tests for ingress protection (IP rating) may be required. All testing must be performed by a laboratory that is UKAS-accredited or recognized under a mutual recognition agreement. The test reports form the basis of the declaration of conformity.
The Role of the UK Approved Body
For higher-risk products, or where the manufacturer does not have full confidence in self-declaration, a UK Approved Body can be involved. These bodies are designated by the UK government to assess conformity. For switches and sockets, most products fall under self-declaration, but the involvement of a third-party body can add credibility. The approval body will review the technical file and may conduct factory inspections and sample testing. MORDIO works with recognized testing laboratories to ensure its products meet all requirements without unnecessary delays.
Differences Between UKCA and CE Marking
While UKCA and CE marking share similar principles, there are key differences:
- UKCA requires compliance with UK designated standards (BS versions), whereas CE uses harmonized European standards (EN versions).
- The declaration of conformity must reference UK regulations, not EU directives.
- The UKCA mark must be affixed before placing on the GB market; CE marking alone is no longer accepted for GB (except for existing stock placed before the transition end).
- For products already CE marked, manufacturers may need to reassess if the UK standards differ.
Manufacturers should always check the latest UK government guidance, as rules may evolve. MORDIO continuously monitors regulatory changes to ensure its product lines remain compliant.

Compliance requirements vary by product classification, destination country, importer role, intended use, and date. Treat standards and marks mentioned in this article as research starting points rather than legal advice or a complete market-entry checklist. Before approving production or packaging, obtain written confirmation of the current requirements from the responsible authority, an accredited conformity-assessment body, or a qualified local compliance professional. Confirm the exact product model, applicable standard edition, required tests, permitted marks, technical-file contents, labeling, registration, importer obligations, and customs documents.
