CE certification: the full process, from testing to the mark

Type "CE certification" into a search bar and you'll get results implying there's a certificate to apply for, an office to submit to, and a badge that lands in your inbox once someone official signs off. None of that is quite right. There is no EU body that "certifies" a product in the way a driving test certifies a driver. What there is, instead, is a process: a manufacturer works through a set of legal obligations, decides (or has decided for them) whether a third party needs to check the work, and finishes by signing a document that puts their own name on the line. Call it certification if you like, since everyone does, but understanding what's really happening underneath that word is the difference between doing this properly and discovering a gap during a customs inspection.

This matters more than it used to. The European Commission's Safety Gate report for 2025 recorded 4,671 validated alerts for dangerous non-food products across the EU and EEA, a 13% increase on the year before, with 5,794 follow-up enforcement actions, the highest figures since the system began tracking them. Electronics, toys and childcare items led the categories. Market surveillance authorities are not slowing down, and a rushed or misunderstood CE certification process is exactly the kind of thing that surfaces once a product is already on shelves.

What "CE certification" actually means

CE marking runs on a self-declaration system for most products. For the large majority of consumer electronics and general hardware, the manufacturer assesses their own product against the applicable EU directives and regulations, tests it (or has it tested) against the relevant harmonised standards, compiles a technical file, and signs a Declaration of Conformity. No external body has to approve any of that before the product ships. The manufacturer's signature is the certification.

A smaller set of higher-risk product categories, including medical devices, certain machinery, pressure equipment and some radio equipment configurations, require a notified body, an independent organisation designated by an EU member state, to check part or all of that assessment before the CE mark can legally go on. Whether you fall into the self-declaration majority or the notified-body minority depends entirely on which directives apply to your specific product, not on how the manufacturer would prefer to handle it.

The process, step by step

1. Identify every directive and regulation that applies. Most electronics sit under two or three at once: commonly the Low Voltage Directive, the EMC Directive, and the Radio Equipment Directive if the product transmits wirelessly. Products with a network connection increasingly also trigger the Cyber Resilience Act. Missing a directive here is the single most common root cause of a failed CE certification, because everything downstream is scoped against this list. 2. Identify the harmonised standards for each directive. These are the specific technical standards (EN 60950, EN 300 328, and similar) that, if met, create a legal presumption of conformity with the directive's broader "essential requirements." Working from the actual standard numbers, rather than a generic checklist, is what separates a defensible technical file from a vague one. 3. Work out your conformity assessment route. This is the fork in the road: internal production control (Module A, self-declaration) for most low-risk categories, or a route involving a notified body (Modules B through H) for higher-risk ones. Our notified body guide covers exactly when the third-party route becomes mandatory rather than optional. 4. Test the product against the relevant standards. Whether that's in-house or at an accredited lab depends on your equipment and the standard itself; EMC and radio testing in particular usually needs a proper chamber. This is also where the majority of the cost in CE certification actually lives, not in any registration fee. 5. Assemble the technical file. Design drawings, the risk assessment, test reports, a list of applied standards, and manufacturing information all sit in one dossier that has to exist before the product ships and be retrievable for at least ten years afterward. Our technical file guide walks through exactly what belongs in it. 6. Sign the Declaration of Conformity. This is the legal document, and the actual certification event: a manufacturer's formal statement, made under their sole responsibility, that the product meets every directive identified in step 1. See our Declaration of Conformity guide for the required fields. 7. Apply the CE mark correctly. A fixed-proportion symbol at a minimum height, placed on the product itself wherever practical, with a notified body's four-digit number alongside it if one was involved in step 3.

Self-declaration vs notified body, side by side

Even self-declaration isn't a shortcut through the underlying work: the manufacturer still has to do genuine testing and hold genuine evidence. It only removes the requirement for someone else to check that evidence before the product ships.

What actually drives the timeline

Timelines for CE certification vary by an order of magnitude depending on which route applies, and the honest answer to "how long does CE certification take" is that testing lab and, where relevant, notified body capacity is usually the bottleneck rather than the paperwork itself. A straightforward self-declared product with standard EMC and safety testing can realistically move from finished prototype to a signed Declaration of Conformity in a matter of weeks if the lab has capacity. Products needing a notified body are a different story: capacity across the EU's designated bodies has been under real strain in 2026, with roughly 45–50 bodies currently designated under the Medical Devices Regulation compared with around 80 under the older directive it replaced, leaving an estimated backlog of over 15,000 pending applications across all currently active notified bodies. If your product needs third-party assessment, booking a slot early is not optional caution; it's the actual critical path.

What CE certification costs

There's no fixed fee for CE certification, but the ranges are consistent enough to plan around. Self-declared wireless products typically run from roughly €1,500 to €3,000 or more for EMC and radio testing alone, while products requiring notified body involvement commonly exceed €13,000 once assessment fees are added on top of testing. Our dedicated CE marking cost guide breaks down each line item in more detail, but the short version is that testing, not registration or paperwork, is where most of the budget goes.

Where manufacturers get it wrong

The most expensive mistake isn't a failed test. It's discovering the wrong assessment route after the product is already tooled up. A manufacturer who assumes self-declaration applies, orders packaging printed with a bare CE mark, and only later discovers their product category needs a notified body is looking at a reprint on top of the delay. The safer order of operations is always: confirm the applicable directives and assessment route first, then test, then finalise packaging artwork.

As one compliance reviewer we work with put it while auditing a client's pre-launch checklist: "the question I ask first isn't 'has it been tested', it's 'do you actually know which directives you're testing against', because I've seen a beautifully documented EMC report attached to a product that also needed a machinery risk assessment nobody had started. That gap doesn't show up until an inspector asks for the full technical file, not the parts you remembered to do."

The second common error is treating "self-certification" as meaning "no evidence needed." Self-declaration removes the notified body checkpoint, not the underlying legal requirement to hold genuine test reports and a complete technical file. A signed Declaration of Conformity with nothing behind it is not a lesser version of compliance. It's non-compliance with a signature on it, and it's arguably easier for an inspector to identify than a product that was never marked at all, because the paperwork trail invites exactly the scrutiny it can't survive.

Getting started

If you haven't yet worked out which directives apply to your specific product, that has to come before any of the steps above make sense. Our free requirements checker walks through your product's category and features and returns the applicable EU, UK and US regulations, each linked to its official source, so you know whether you're looking at a self-declaration route or a notified body one before you book any lab time.

FAQ

Is CE certification the same as CE marking? In everyday use, yes: most people use the two terms interchangeably. Technically, CE marking is the symbol and the legal marking requirement, while the underlying work (testing, documentation, and either self-declaration or notified body assessment) is the certification process that earns the right to apply it.

Do I need a notified body for CE certification? Only if your product falls into a category where the applicable directive specifically requires third-party assessment, such as certain medical devices, machinery, or radio equipment configurations. Most standard consumer electronics can be self-declared under Module A. Check our notified body guide for the categories where it's mandatory.

How long does CE certification take? For self-declared products with standard testing, often a matter of weeks once a test lab has capacity. For products needing a notified body, plan for months, since notified body capacity across the EU has a real backlog in 2026 and booking early is the main lever you control.

Can I do CE certification myself without a consultant? Yes, for the many products where self-declaration applies. The legal requirement is that the manufacturer does genuine, defensible work, not that a third party is hired to do it. Where the assessment route genuinely requires a notified body, that part cannot be self-performed, since it's defined by law as third-party.

What happens if I skip CE certification and just add the mark? Applying a CE mark without having actually completed the underlying assessment is a legal misrepresentation, not a shortcut. It carries the same market surveillance and enforcement exposure as a product that fails testing, with the added problem that there's no genuine technical file to fall back on if a regulator asks for one.
