About EMC Directory
EMC Directory brings UK EMC test labs and consultancies together in one place. Every listing is structured the same way: standards and regulations covered, accreditations, test types, chamber and facility types, frequency range and industries served, so you can compare providers directly, on the specifics that matter for a project.
Why EMC Directory
EMC Directory draws on 30+ years' tactical and strategic leadership across operations, quality, engineering and project delivery in the electronics manufacturing sector, including senior roles inside global OEMs and Tier 1 suppliers under a range of international ownership. That experience spans new product introduction, supplier selection and global account management across several regulated, safety-critical industries, where EMC compliance testing is one of the gates a product has to clear before it can ship. This practical, first-hand experience of how choosing the right test partner can affect your project's cost and timeline shapes what's captured on every listing here.
What "capability" actually means in EMC testing
"Full Compliance Testing" covers real range. A lab with a semi-anechoic chamber testing to the harmonised standards for CE marking and the designated standards for UKCA marking, and a specialist lab testing to automotive, military or aerospace standards, sit under related headings but are not interchangeable. Accreditation adds another layer of specificity: an ISO/IEC 17025 accreditation only covers the tests and frequency ranges in the lab's own schedule, and the standards a lab is set up for decide whether its report will be accepted in the market you are selling into. Pre-compliance testing helps find problems early, but it does not replace a formal test report. Facility type matters too: a fully anechoic chamber, a semi-anechoic chamber, a reverberation chamber and an open area test site each suit different standards, worth knowing going in.
This is exactly the detail the standards, accreditation, test type and facility filters on this directory are built around.
Built on what actually determines fit
Every listing captures standards and regulations covered, accreditations, test types, chamber and facility types, frequency range, testing location and industries served, structured the same way throughout so you can filter and compare providers on the specifics that matter. Listings are reviewed and kept current, and each one carries a "Last Updated" date so you know how fresh the information is. We make reasonable efforts to keep every listing accurate and current, though details can change faster than any listing is updated. Always verify accreditations, capacity and trading status directly with a company before relying on it for a business decision. See what "Verified" means for the full picture.
We've also built the tools for the part of the process that usually happens over email and spreadsheets: save the providers you're considering to a shortlist, compare their accreditations and capabilities side by side, and send one enquiry to all of them at once - saving you time, and widening your reach without extra effort.
Coverage
The directory currently lists 30+ UK EMC testing providers and consultancies across eight categories: Full Compliance Testing (20), Pre-Compliance Testing (11), Military & Aerospace Testing (8), Automotive EMC Testing (5), EMC Consultancy & Design (5), Marine Type Approval (5), Wireless & Radio Testing (5) and TEMPEST & Security Testing (2). Coverage spans pre-compliance specialists through to accredited full compliance labs, and general-purpose test houses through to providers built around a specific sector: aerospace and defence, medical devices, automotive, railway and marine among them. New listings are added, and existing ones rechecked, on an ongoing basis, so coverage keeps growing rather than sitting as a fixed snapshot.
Who it's for
- Buyers and engineers sourcing a UK EMC test lab or EMC consultancy: product and compliance teams planning a first test, design engineers booking a pre-compliance scan ahead of formal testing, and procurement teams qualifying a lab for ongoing work. Whether it's a one-off scan or an ongoing programme, the filters are built around the detail that actually determines fit.
- EMC testing providers and consultancies, who can submit a new listing to put their standards, accreditations and capabilities in front of buyers filtering on exactly those criteria.
