Conformity assessment routes

Certain conformity assessment procedures allow for self-declaration of conformity by the manufacturer.

Other regulations, for those typically more 'high-risk' products, may require third-party conformity assessment.

You should check the sector-specific guidance which applies to your product to find out whether you can self-declare or need to use a third-party conformity assessment to show the UK essential requirements have been met.

CE-marked products

The government has laid legislation to continue recognition of goods that meet current EU requirements beyond 31 December 2024.

If you are following European harmonised standards to demonstrate that your product meets the EU essential requirements in the relevant EU legislation, and you want to place that product on the GB market, you should also note the following:

• where UK law allows for a product to meet the EU essential requirements, there is no specific reference to harmonised standards giving rise to a 'presumption of conformity' with the essential requirements; however, where both EU harmonised standards and UK designated standards remain aligned, manufacturers may still rely on the harmonised standard to demonstrate they have met the relevant EU essential requirements to place a product on the GB market
• in a small number of cases where there is a difference between designated standards and European harmonised standards, the conformity assessment procedures that need to be complied with before the CE-marked product can be placed on the GB market may be affected
• if a designated standard has a restriction that the equivalent European harmonised standard used does not, you may need to take additional steps to bring that product into compliance with the safety requirements before placing the product on the GB market

You should consult the sector-specific guidance for your product. You can speak to your solicitor or trade association if you are unsure which regulations apply to your products.

Self-declaration for the UKCA marking

If you self-declare for the CE marking, you can still self-declare for the UKCA marking.

Please see the following legislative areas where self-declaration of conformity for UKCA marking is permitted and, in some instances, may be required:

Legislation	Scope of products which can be self-declared
Electromagnetic Compatibility Regulations 2016	All products
Toy (Safety) Regulations 2011	All products except where designated standards covering the essential requirements either do not exist or have not been applied (either in full or in part) by the manufacturer. Or where one or more of the designated standards has been published with a restriction.
The Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Regulations 2012	All products
Medical Devices Regulations 2002	Some Class 1 devices
Radio Equipment Regulations 2017	All products except where designated standards covering the essential requirements either do not exist or have not been applied (either in full or in part) by the manufacturer.
The Pressure Equipment (Safety) Regulations 2016	Category I pressure equipment
Construction Products Regulations (Regulation (EU) 305/2011 as brought into UK law and amended)	Products within scope of System 4
Recreational Craft Regulations 2017	Certain categories of recreational craft as specified in the legislation
The Electrical Equipment (Safety) Regulations 2016	All products
The Supply of Machinery (Safety) Regulations 2008	Any machinery which is not in Schedule 2, Part 4 of the Regulations. Any machinery that is in Schedule 2, Part 4 where the requirements of all relevant designated standards have been applied in full and where those standards cover all the applicable essential requirements.
The Equipment and Protective Systems Intended for Use in Potentially Explosive Atmospheres Regulations 2016	Equipment-group II, equipment category 3
Personal Protective Equipment Regulations (Regulation (EU) 2016/425 as brought into UK law and amended)	Category I personal protective equipment
Ecodesign for Energy-Related Products Regulations 2010	All products listed in Schedule 1 with the exception of boilers as specified in retained Commission Regulation (EU) 813/2013

Mandatory third-party conformity assessment for the UKCA marking

Where mandatory third-party conformity assessment was required for CE-marked products, it is also required for UKCA-marked products.

While the current position is that after 11pm on 31 December 2024 all products must be UKCA marked, which requires conformity assessment by a UK Approved body, the government has laid legislation to continue recognition of goods that meet current EU requirements, including CE marking, for a range of products.

This means that goods that meet EU requirements, including the applicable conformity assessment procedures (which in some cases must be undertaken by EU-recognised bodies) can continue to be placed on the GB market.

Reducing re-certification and re-testing costs for UKCA marking

The current position is that where a manufacturer has taken steps under an EU conformity assessment procedure prior to 31 December 2024 but the product has not been placed on the GB market by that date, those steps will be recognised and will count towards the equivalent conformity assessment procedure required under the UKCA regime (until any certificate expires or until December 2027, whichever is the sooner).

This provision was aimed at ensuring that manufacturers do not have to undertake expensive re-testing once goods that meet EU requirements were no longer recognised on the GB market. However, as part of the process for continuing the recognition of goods that meet current EU requirements beyond 31 December 2024, the government will also be considering this provision, since it may no longer have any value in its current form.

This measure applies across all module types for the following regulations as they apply in GB:

• Noise Emission in the Environment by Equipment for Outdoor Use Regulations 2001
• Supply of Machinery (Safety) Regulations 2008
• Ecodesign for Energy-Related Products Regulations 2010 (with respect to boilers in accordance with Article 4 of Commission Regulation (EU) No 813/2013)
• Toys (Safety) Regulations 2011
• Explosives Regulations 2014
• Pyrotechnic Articles (Safety) Regulations 2015
• Electromagnetic Compatibility Regulations 2016
• Simple Pressure Vessels (Safety) Regulations 2016
• Lifts Regulations 2016
• Pressure Equipment (Safety) Regulations 2016
• Equipment and Protective Systems Intended for Use in Potentially Explosive Atmospheres Regulations 2016
• Non-automatic Weighing Instruments Regulations 2016
• Measuring Instruments Regulations 2016
• Recreational Craft Regulations 2017
• Radio Equipment Regulations 2017
• Regulation 2016/425 on personal protective equipment as it applies in GB
• Regulation 2016/426 on gas appliances as it applies in GB

Technical documentation

Record keeping

You, or your authorised representative (where allowed for in the relevant legislation), must keep documentation to demonstrate that your product conforms with the regulatory requirements.

This must generally be kept for 10 years after the product is placed on the market. The relevant period is specified in the applicable legislation.

This information can be requested at any time (within the time period set out by legislation) by market surveillance or enforcement authorities to check that your product conforms with the regulatory requirements.

The information you must keep will vary depending on the specific legislation relevant to your product, but if requested you must provide enforcement authorities with all information and documentation necessary to demonstrate that a product is in conformity. This information must be provided in English.

This could include, but is not necessarily limited to, the following:

• how the product is designed and manufactured
• how the product has been shown to conform to the relevant requirements
• the addresses of the manufacturer and any storage facilities

You should keep the information in the form of a technical file which can be supplied, if requested, by a market surveillance authority.

UK Declaration of Conformity

The UK Declaration of Conformity is a document which must be drawn up for most products lawfully bearing a UKCA marking before they are placed on the market. We recommend that manufacturers have their UK Declaration of Conformity and their EU Declaration of Conformity in separate documents.

The UK Declaration of Conformity should be available to market surveillance or enforcement authorities on request.

The information required on the UK Declaration of Conformity is largely the same as what was required on an EU Declaration of Conformity. This can vary depending on the applicable legislation but generally should include:

• the name and full business address of the manufacturer and that of your authorised representative (if applicable)
• the product's serial number, model or type identification
• a statement, stating you (the manufacturer) take full responsibility for the product's compliance
• the details of the approved body which carried out the conformity assessment procedure (if applicable)
• the relevant legislation with which the product complies
• references to the relevant designated standards, including the date of the standard or references to other technical specifications
• the name and signature of the person authorised to sign on behalf of the manufacturer or their authorised representative
• the date the declaration was issued
• supplementary information (if applicable)

You will need to list:

• relevant UK legislation (rather than EU legislation) (ODS, 5.29 KB). This can be listed as a reference to the statutory instrument number (where applicable) or the full title
• UK designated standards rather than standards cited in the Official Journal of the European Union
