Lists of standards that businesses can use to show their products, services or processes comply with essential requirements of legislation.
Many businesses currently use European harmonised standards to provide presumption of conformity with relevant EU law. As the UK retained many of the requirements of EU law at the end of the transition period the essential legal requirements that businesses must meet in the UK did not change. Therefore, all harmonised standards that gave presumption of conformity with EU law became designated standards in the UK on 1 January 2021. Designated standards can be used to provide a rebuttable (i.e. could be countered by evidence) presumption of conformity to GB law in the same way that harmonised standards are used to demonstrate compliance with EU law.
Harmonised standards remain the relevant standards for placing goods on the Northern Ireland market, where EU rules continue to apply. However, the Government is seeking to find a new balance in the Northern Ireland Protocol to place it on a more sustainable footing that would impact on how products are regulated in NI.
A designated standard is a standard, developed by consensus, which is recognised by government in part or in full by publishing its reference on GOV.UK in a formal notice of publication. Depending on the product, a designated standard can be a standard adopted by any of the four following recognised standardisation bodies, or by international standardising bodies (including the International Organization for Standardization (ISO), International Electrotechnical Commission (IEC) and International Telecommunication Union (ITU).
- British Standards Institution (BSI)
- European Committee for Standardisation (CEN)
- European Committee for Electrotechnical Standardisation (CENELEC)
- European Telecommunications Standards Institute (ETSI)
Note: Designated standards do not replace the mandatory essential legal requirements but offer a technical solution to fulfil them. The manufacturer retains full responsibility for ensuring the product complies with the relevant essential requirements. The content of the standard is the responsibility of the recognised standardisation bodies, with BSI as the UK’s National Standards Body representing the interests of UK stakeholders. From 1 January 2021, when deciding if a standard is appropriate for designation, the government will check how far it covers the various essential requirements set out in the relevant legislation.
The government will ensure that the standards applicable in the UK best suit the UK’s needs, including designated standards businesses can use to provide presumption of conformity with GB law. It will update the list of designated standards as and when necessary to retain and enhance the high levels of consumer safety. It may decide not to designate or to designate with restriction. Any such restrictions will be published on GOV.UK, and businesses should check frequently.
In the interests of transparency, the government will make its proposals to publish references to standards publicly available for 28 days. Interested parties may object to their publication within this timeframe. The references will be published to designate the standards on day 29, unless the proposal is withdrawn or amended before that date.
References of designated standards
Designated standards are prefixed “BS”, “EN”, “EN ISO” or “EN IEC”. The “EN” prefix indicates that the standard has been adopted by a European standardising body. Where the designated standard specified in the notice of publication is prefixed “EN” it is acceptable to reference this version in technical documentation, or a version of the same standard with a national prefix. This is because European standards are adopted identically by the 34 national members of CEN and CENELEC.
For example: BS EN 71-1:2014+A1:2018, DIN EN 71-1:2014+A1:2018, or simply EN 71-1:2014+A1:2018 are all equally acceptable.
While the essential legal requirements in GB remain the same as the equivalent EU law, the informative Annex ZA/ZZ and any references to EU law in designated standards should be read as applying to the legislation for GB in the same way, subject to any restrictions or points made in the relevant notice of publication. This will change if and when the essential legal requirements in GB change. We have asked BSI to ensure that any new or revised designated standards map across to the essential legal requirements in GB.
