Experts in EMC pre-compliance, problem solving and design for EMC

Unit 3 Compliance is a West Yorkshire test lab and consultancy specialising in Electro-Magnetic Compatibility (EMC) testing, troubleshooting/problem solving, pre-compliance and product design support.

We have the skills and the tools to fix your EMC problems quickly and effectively.

COVID-19 Update: Unit 3 Compliance is still open with plenty of products coming through the door for testing. Our Bradford test laboratory is open with common sense working practices (daily cleaning of key areas, social distancing, etc). Customers are welcome on site to witness tests or to send equipment for remote testing. Design reviews and consultancy services are unaffected.

I hope that you are remaining safe, well, and productive. Very much looking forward to a cup of tea and a catch up when things have settled down.

See you soon,


EMC Test Lab

Our EMC test lab is well equipped and capable of testing to a wide range of emissions and immunity standards. These test facilities are at your disposal for a much lower price than a big name test lab and are backed up by our in depth engineering, fault finding and problem resolution experience. Our flexibility and low cost makes us an ideal partner for any EMC pre-compliance testing you require.

From integrating wireless capability such as Wi-Fi or Bluetooth to supporting your product through manufacturing and into service we’ve got the EMC knowledge you need to make your product a success.

In addition we offer environmental test services such as temperature/humidity and vibration/shock testing.

CE Marking + More

To get your product onto the global market you need to be up to speed with all the relevant regulations but if you aren’t familiar with them this can be a time consuming activity. We can advise you on the requirements for your product and assess it for CE (EMCD and RED for Europe), FCC (USA), IC/ISED (Canada) and more. In the event that there are problems then we are here to help you solve them with a depth of technical knowledge

It’s not just EMC either – we also advise our customers on electrical safety (LVD, UL), RoHS, WEEE – everything you need to get your product on sale. We also love a good a report and can help you build or review your Technical File and associated documentation.


The approach we take is to help you at all stages of the design to ensure your products are delivered on time and on budget.

Your products are our products – we aren’t happy until you are happy. When you engage with us we become your compliance department, bringing the tools and experience you need to get the job done.
