Smart Watch Certification in the UK: Requirements, Process and Timelines
Smart watches are body-worn radio devices with a lithium battery, and many connect to phones and the internet, which brings in cybersecurity rules as well. Great Britain has its own UKCA regime but continues to recognise CE marking for most products, while the PSTI Act adds mandatory security rules for connected consumer devices.
To import and sell smart watches in the UK you will typically need:
UK Radio Equipment – Smart watches are radio equipment under the UK Radio Equipment Regulations 2017.
UK PSTI – Wearables are consumer connectable products, so the PSTI security requirements apply.
UKCA – The product needs a UK Declaration of Conformity and the UKCA mark, or CE where the UK continues to recognise it.

Step-by-step: how to certify a smart watch for the UK
Confirm scope for your model. Share the datasheet, materials, any radio, battery or power-supply details and the HS code so we can confirm exactly which of the schemes above apply – in the UK you decide between UKCA and CE, then check whether the PSTI security regime applies to connected products.
Set up the local party. Make sure a UK importer or UK-based economic operator is identified on the product, packaging or accompanying documents.
Assess under the UK Radio Equipment Regulations. Radio, EMC and safety testing to designated standards – normally the same EN standards used for CE.
Meet the PSTI security requirements. No universal default passwords, a published vulnerability-disclosure policy and a stated minimum security-update period, backed by a statement of compliance.
Sign the UK Declaration of Conformity and mark the product. Use the UKCA mark (or CE, where the UK continues to recognise it) with the UK importer's details.
Keep it valid. Keep the UK Declaration of Conformity and technical documentation for 10 years, publish and honour the PSTI security-update period where it applies, and watch for changes in the UK's CE-recognition policy.
Testing and documentation
Testing your smart watch will need
Radio tests for Bluetooth, Wi-Fi and any cellular or NFC function
EMC emissions and immunity (EN 301 489 series or local equivalent)
Safety to IEC 62368-1
SAR testing for wrist-worn transmitters where the output power requires it
Battery safety to IEC 62133-2 and UN 38.3 transport testing
Exact standards and editions depend on the model and the scheme; we confirm the test plan before any sample is shipped.
Documents to prepare
Product datasheet and user manual
Radio module details (bands, output power, antenna gain)
Schematics, PCB layout and block diagram
Battery and charging-cradle datasheets and certificates
Security and software-update information for the companion app
Label and packaging artwork
UK Declaration of Conformity (or EU DoC where CE is used)
PSTI statement of compliance for connectable products
FAQs: smart watch certification in the UK
Is UK Radio Equipment mandatory for smart watches in the UK?
Yes. Smart watches are radio equipment under the UK Radio Equipment Regulations 2017. GB version of RED covering radio, EMC and safety for wireless products.
What certifications do smart watches need in the UK?
The core requirements are UK Radio Equipment, UK PSTI, UKCA. The table above explains why each one applies.
Does a foreign manufacturer need a local representative in the UK?
The UK importer's name and address must appear on the product, packaging or documents. A non-UK manufacturer can also appoint a UK authorised representative to hold the technical documentation. By scheme – UK Radio Equipment: Depends; UK PSTI: Depends; UKCA: Depends – UK importer details must appear on the product.
How long does smart watch certification take in the UK?
Typical timelines by scheme: UK Radio Equipment: 4–8 weeks; UK PSTI: 2–4 weeks; UKCA: 3–8 weeks. Schemes can run in parallel once samples and documents are ready. Send us your model details for a realistic plan.
Can I reuse existing test reports for the UK?
Yes. Test reports to the EN standards used for CE marking are normally accepted for UKCA too, and CE-marked products can in most cases be placed on the GB market as they are. PSTI needs its own statement of compliance.
