UKCA marking for machinery and electrical equipment

What UKCA marking is for

UKCA stands for UK Conformity Assessed. It is the marking used for most goods placed on the market in Great Britain, which covers England, Scotland and Wales. It shows that the product meets the applicable GB legislation. It is not a European mark and it is not administered by the EU.

Northern Ireland has a different position. Goods placed on the Northern Ireland market generally use CE marking, or UKNI marking where a UK approved body has been involved in the conformity assessment. UKCA marking is not the route for Northern Ireland. A business shipping to both markets therefore needs to know which destination each order serves.

The UKCA mark covers machinery, electrical equipment, radio equipment, pressure equipment, toys and other regulated categories. Each category has its own regulations, standards and conformity route. The mark is the same, but the evidence behind it is not. A machinery file and an electrical file answer different legal questions.

How UKCA sits beside CE in 2026

The UK has extended the recognition of CE marking indefinitely for most product regulations in Great Britain. For many machinery and electrical products, a valid CE mark is enough for the GB market, and UKCA marking is not compulsory. That position followed a series of extensions and a change in policy, and it is the practical starting point for most importers.

Indefinite recognition does not mean the two systems are identical. A CE mark is based on EU law and EU harmonised standards. A UKCA mark is based on GB law and designated standards. The standards are often the same in substance, but the legal reference, the declaration and the market surveillance route are different. If a product is CE marked against a standard that has not been designated in GB, the file may not support a UKCA claim.

Some product areas have their own transition rules, including medical devices, construction products and certain chemicals. Do not generalise from machinery to every category. Check the specific regulation for the product, and check the current gov.uk guidance, because the UK has changed these dates more than once.

Who carries the duty

The manufacturer is the business that designs or makes the product, or has it made under its own name. It prepares the technical documentation, carries out the conformity assessment, draws up the declaration and applies the marking. Where the manufacturer is outside the UK, the importer takes on verification duties and must ensure that the product can be traced.

The importer must not place a product on the GB market unless it is compliant. That means checking the marking, the declaration, the instructions and the technical file. The importer's name and address normally go on the product or its packaging, so that the market surveillance authority knows who is responsible for the unit in GB.

A distributor has a lighter but still real duty. It must act with due care and must not supply a product it knows or should know is non-compliant. If the distributor changes the product or places it under its own name, it can take on manufacturer duties. A private label arrangement is a common example.

The evidence pack

A UKCA file normally contains the technical description, drawings, circuit diagrams, risk assessment, standards list, test reports, instructions and the declaration of conformity. For machinery, the risk assessment is central. For electrical equipment, the evidence usually covers insulation, creepage and clearance, temperature rise, fault conditions and the enclosure.

The declaration must identify the product, the manufacturer or importer, the legislation and the standards used. It must be signed by someone with authority. A declaration copied from an EU file often cites EU directives and harmonised standards. Those references need to be replaced with the GB regulations and designated standards, or the declaration does not describe the GB product.

Keep the file for the period required by the regulation and make it available to the authority on request. The file can be held outside the UK, but the importer needs a practical route to produce it. A PDF folder on a sales manager's laptop is not a controlled document. Use a version, an owner and a review date.

Testing and standards

The test programme should follow the designated standard for the product and the GB regulation. In many cases the technical content matches the EU harmonised standard, so an existing test report can be used as evidence. That is not automatic. The report must cover the right version, the right clauses and the actual production configuration.

A common gap is a report on a prototype that differs from the shipped product. Another is a report that covers only one variant of a family. A third is a report from a laboratory whose scope does not include the test method. The buyer should check the scope, the date and the sample identification, not just the pass page.

Where a UK approved body is required, the route takes longer. Build that into the launch plan. The approved body will want the technical file, the risk assessment and the test evidence before it can issue the certificate. A late application can delay the first shipment even when the design is ready.

Applying the mark and the label

The UKCA mark must be visible, legible and permanent. It goes on the product or, where that is not possible, on the packaging or the accompanying documents. The rules allow some flexibility for small products, but the mark should not be hidden inside a sealed housing. The importer's details and the product identification also need to be present.

The mark must be proportional and must not be confused with other marks. Do not add a UKCA mark to a product that has not been assessed against GB law simply because a customer asked for it. A false mark is worse than an absent one. It creates a misleading claim and can lead to enforcement action.

If the product already carries a CE mark, the two marks can appear together where both routes apply. Keep the declarations separate. One document that mixes EU and GB references is difficult to audit and easy to get wrong.

A checklist for importers

Before the first shipment, confirm the product category and the GB regulation. Confirm whether CE recognition covers the product or whether UKCA is needed. Check the designated standard and the test evidence. Check the declaration for GB references. Check the marking, the importer details and the instructions.

Then check the supplier's change control. A new housing material, a new PCB, a new motor or a new firmware version can affect compliance. The supplier should notify before the change and provide the updated evidence. The importer should have the right to pause a shipment until the file is updated.

Finally, keep a simple register by product: regulation, standard, test report, declaration, marking photo, importer details and review date. That register is the difference between a compliant shipment and a scramble at the border.

• Product category and GB regulation confirmed
• CE recognition checked for the specific product
• Designated standard and test scope verified
• GB declaration with the correct legal references
• UKCA mark and importer details on the product
• Instructions in the required language
• Change notification and file review dates agreed
