A short guide for two audiences: companies looking to source UK EMC testing, and EMC testing providers looking to be found.

For Buyers

1. Start with a category or a search. Use the EMC Testing Services category, or search directly for a company or location.

2. Filter by what actually matters for your project. The filter panel covers:

• Standards & regulations covered — CE, UKCA, FCC, MIL-STD-461, RTCA DO-160, CISPR 25 and more
• Accreditations — UKAS, ISO/IEC 17025, ISO/IEC 17065 and other recognised schemes
• Test types — radiated and conducted emissions, immunity, ESD, surge, bulk current injection and more
• Chamber/facility types — fully or semi-anechoic chambers, screened rooms, open area test sites
• Testing location — in-lab only or on-site/mobile testing capability
• Industries supported — so you can find a provider with real experience in your sector

3. Read the listing, not just the name. Each listing shows a provider's accreditations, standards coverage, headcount band, and a "Last Updated" date so you know how current the information is. Company registration numbers link through to Companies House where available, and where a provider holds a UKAS accreditation we reference the specific laboratory number.

4. Get in touch. Use the "Contact [Company]" button on any listing to reach out directly.

For EMC Testing Providers

Get listed. If your company isn't listed yet, submit your listing — it takes a few details (company name, website, contact info and address) to get started.

Manage your listing. Use Business Login to sign in or create an account and keep your listing current.

Keep your details accurate. Buyers filter heavily on accreditations, standards and industries served — an accurate, complete listing gets found by the right customers. If anything on your listing needs correcting, get in touch and we'll update it.
