Essential information for suppliers of electrical equipment, including CE / UKCA marking

To fully understand this guidance, it is important to note the difference between the United Kingdom and Great Britain:

  • UK: England, Scotland, Wales and Northern Ireland
  • GB: England, Scotland and Wales

This guidance is for England, Scotland and Wales

Electrical equipment is required to comply with the Electrical Equipment (Safety) Regulations 2016, which have been amended by the Product Safety and Metrology etc (Amendment etc) (EU Exit) Regulations 2019. There are separate provisions made for Northern Ireland to take account of the Northern Ireland Protocol whilst it is in force.

The Regulations apply to electrical equipment that is designed to be connected to a domestic mains electricity supply, as well as to some industrial equipment. Components of electrical equipment are also covered if they are to be supplied as separate items.

Electrical equipment designed for use between 50-1,000 volts AC or 75-1,500 volts DC must be safe, constructed in accordance with principles constituting good engineering practice and conform to specific regulatory safety objectives.

If the electrical equipment complies with a designated standard* (such as the EN 60335 series of standards on the safety of domestic electrical appliances), it is automatically taken to be safe. There are specific requirements for the manufacturer of the product, including affixing theĀ CE / UKCA mark, drawing up and holding a declaration of conformity, and keeping technical information for inspection purposes.

[*'Designated standards' are those approved by the Secretary of State and published by the British Standards Institution (BSI).]

Second-hand items (including items for hire and equipment supplied as part of a furnished accommodation) are required to satisfy the principal elements of the safety objectives only. They are not required to have the CE / UKCA mark etc.


Electrical equipment must be:

  • constructed in such a way to ensure that it can be used safely and for the purpose that it was made
  • in conformity with the safety objectives contained in Part 2 of, and Schedules 1 and 2 to, the Regulations, including:
    • being marked in accordance with the requirements set out below so that it can be easily traced
    • designed so that the equipment, including its component parts, can be safely and properly assembled and connected
    • instructions and information required for the equipment to be used safely must be marked on the equipment or in an accompanying notice
    • operate at a safe temperature with no dangerous high resistance connections / joints, arcing or radiation
    • have adequate insulation for foreseeable conditions
    • have the right technical information available, demonstrating compliance with UK marking requirements and a 'declaration of conformity'



Manufacturers must have adequate internal production control (quality assurance) as a means of satisfying conformity, achieved through taking responsibility for the technical documentation and monitoring manufacturing processes. Either the manufacturer or (by written mandate) the authorised representatives should draw up a declaration of conformity in accordance with Schedule 8 to the Regulations and apply the CE / UKCA mark (as below).

If the electrical equipment complies with a designated standard, there is a presumption that it meets the principal safety objectives.


A manufacturer or their authorised representative must do the following.

Ensure that the electrical equipment bears a type, batch or serial number, or other element, allowing its identification.

Indicate on the electrical equipment the manufacturer's name, registered trade name or registered trade mark and the postal address at which they can be contacted. If it is not possible to indicate these on the equipment itself, then it may be indicated on the product packaging or accompanying documents. These have to be legible and easily understood by the end users and market surveillance authorities. In the UK it must be in English.

Affix a CE / UKCA mark to the equipment, the packaging, instruction sheet or guarantee certificate. The CE / UKCA mark is a declaration that the equipment complies with the Regulations.

Manufacturers must also draw up and hold a 'declaration of conformity', which should contain:

  • the product model, type, batch or serial number(s) to which the declaration of conformity applies (for traceability purposes)
  • the name and address of the manufacturer or their authorised representative
  • a description of the electrical equipment (may include a colour image where necessary for the identification of the electrical equipment)
  • a reference to the relevant designated standards used to assess compliance (if no designated standard, then a reference to other specifications)
  • identification of the person who will enter into commitments on behalf of the manufacturer or authorised representative (if appropriate)
  • the place and date of issue

Compile and hold technical documentation, which should contain:

  • a general description of the electrical equipment
  • the conceptual design, manufacturing drawings, details of components, etc, along with information to help interpretation of these
  • a list of the standards with which the electrical equipment complies; or, if standards were not used, a description of what has been done to ensure compliance with the general safety requirement
  • results and reports of tests, examinations, calculations, etc


An importer is a person or business based in the UK who places equipment on the GB market from a country outside the UK. Importers must not place any electrical equipment on the market unless they have assurances that it complies with the principal safety objectives (see above) and ensure that the manufacturers have met all their obligations in relation to conformity assessment procedures, technical documentation, CE / UKCA marking and labelling requirements. This must be made available to an enforcement body on request.

Importers must also indicate on the electrical equipment their name or registered trade mark and a postal address at which they can be contacted. To assist with the changeover, the UK is applying a transitional period ending on 31 December 2027 to allow UK importers of goods from the European Economic Area (EEA) or Switzerland to provide their details on the packaging or in accompanying documentation as an alternative to placing them on the equipment itself (before Brexit, these business were considered to be distributors).


Manufacturers and importers have additional obligations. They must:

  • carry out sample testing of electrical equipment made available on the market
  • investigate (and keep a register of complaints about) non-conforming electrical equipment and electrical equipment recalls
  • keep distributors informed of any such monitoring


Distributors must also act with care to ensure that they supply only equipment for which the manufacturers and importers have carried out their duties as above. They should verify that the electrical equipment:

  • bears the CE / UKCA mark
  • is accompanied by the required documents
  • the labelling requirements have been complied with
  • the label identifies the importer
  • that instructions and safety information are provided in English

Where a distributor considers or has reason to believe that electrical equipment is not in conformity with the principal elements of the safety objectives or any of the requirements above, the distributor must not make the electrical equipment available on the market until it has been brought into conformity.


The declaration of conformity and the technical documentation must be kept and be available for inspection by enforcement bodies (including Trading Standards) by:

  1. the manufacturer, if they are in the UK
  2. their authorised representative*
  3. if neither of the above, the importer into the UK

These must be kept for a period of 10 years beginning on the day on which the electrical equipment is placed on the market.

[*You can continue to use authorised representatives if they are based in the UK, the EU, the European Economic Area, or Switzerland and Turkey. However, if you need to appoint a new authorised representative to put your goods on the market post-Brexit, the new authorised representative will need to be based in the UK.]


If the electrical equipment is a plug-in device (such as a charger) intended to be connected, without the use of a mains lead or plug, directly to the UK public electricity supply via a socket outlet conforming to BS 1363: 13 A plugs, socket-outlets, adaptors and connection units, the economic operator must ensure that the plug-in device is compatible with socket outlets conforming to BS 1363.

Where the electrical equipment has a flexible lead and plug assembly, such as a vacuum cleaner, and is intended to be connected to the UK public electricity supply by means of a socket outlet conforming to BS 1363, the economic operator must ensure that that plug is a correctly fitted standard plug fitted with a BS 1362 fuse, or is a correctly fitted non-UK plug conforming to the safety provisions of IEC 884-1 and correctly fitted with a compatible conversion plug.

Many modern electrical appliances are now fitted with 'smart' technology, some connected via Bluetooth and others via apps on computer, laptop or mobile devices. Such devices may also be covered by the Radio Equipment Regulations 2017. Information on how the Radio Equipment Regulations 2017 apply in GB may be found on the GOV.UK website.


The Electromagnetic Compatibility Regulations 2016 may also apply. They contain provisions prohibiting electromagnetic emissions from electrical equipment interfering with the operation of other equipment.
