Even with the best intentions, companies can stumble on the road to achieving CE marking or UKCA marking. There are numerous common pitfalls that can delay or derail a compliance effort. The good news is that these pitfalls are well-documented, and with proactive management you can avoid them. In this final article, we highlight several frequent mistakes businesses make in the CE/UKCA certification process and provide guidance on how to steer clear of them. Learning from others’ missteps will help ensure your own product compliance journey is as smooth as possible.
The mistake: Waiting until late in development – or after the product is built – to think about compliance requirements. This “bolt it on at the end” approach is a recipe for trouble. If you only consider regulations at the last minute, you may discover design issues or documentation gaps that require costly rework or cause launch delays. It’s not uncommon for products to fail certification tests or reviews because a key requirement was overlooked during design.
How to avoid it: Integrate compliance from the start. As discussed earlier, make compliance a core part of project planning. By ensuring regulatory requirements are addressed in design, you won’t face nasty surprises at the eleventh hour. This includes doing early risk assessments, consulting standards during design decisions, and maybe even having a compliance expert involved in design reviews. Companies that integrate compliance early consistently report lower costs and fewer delays, compared to those that retrofit compliance later. The quote “ensure products are able to access UK, EU and global markets through accurate and reliable CE marking… We always approach every project with compliance in mind... helps to keep development costs low, and allows for a quicker route to market” from Blue Lightning Solutions exemplifies the value of early integration. In short, don’t treat compliance as just ticking a box at the end – bake it into your project’s DNA.
The mistake: Neglecting the technical documentation (tech file) or producing it haphazardly. Some companies focus only on testing and assume paperwork is a formality, only to find out their submission is rejected due to missing or inconsistent documents. Inadequate documentation is one of the most common reasons a CE/UKCA certification process falters. Examples include missing test data, no formal Declaration of Conformity, outdated drawings, or lack of evidence for compliance with certain clauses of standards. Regulators and certifiers are meticulous – if your documentation doesn’t convincingly show compliance, they can’t approve your product.
How to avoid it: Treat documentation as seriously as testing. Start compiling your technical file early and keep it up-to-date (list all applicable standards and how you meet them, include all required test reports, etc.). Use checklists based on the target directives to ensure you include every required item (such as a risk assessment report, user manual, labeling sample, conformity declaration, etc.). Have someone double-check that the documentation is internally consistent (e.g., the model numbers and specs match everywhere). If you’re unsure what needs to be in the technical file or DoC, consult guidance documents or get expert help. Sometimes involving a compliance consultant to review your documentation can catch omissions before submission. Remember, thorough documentation not only smooths certification – it also forces you to truly confirm every compliance aspect is handled, which is exactly the point.
The mistake: Forgoing pre-compliance or internal testing and going straight to an official lab test with an unvetted product. This can lead to failures in the test lab, which are costly in terms of re-testing fees and time lost while problems are fixed. A related mistake is doing minimal testing on one version of the product and not on all variants (e.g., assuming that if one model passes, a slightly different model will too without verification).
How to avoid it: Test early and often. Conduct pre-compliance tests for critical regulatory aspects (EMC, electrical safety, etc.) on prototypes or early units. This will uncover issues when they are easier to fix. Also, if your product has variations (different configurations or options), evaluate which differences could affect compliance (like a higher power model that might emit more electromagnetic noise, or a version with a different casing material affecting flammability) and test accordingly. It’s a pitfall to assume one-size-fits-all for testing; regulators expect that each version sold is compliant. Utilize accredited labs for informal pre-tests or invest in some in-house testing capabilities if feasible. When you do go for official certification testing, you’ll be much more confident of passing, potentially saving the expense of multiple test rounds. In short, don’t treat the certification lab as a QA department – do your own QA first.
The mistake: Misunderstanding what regulations apply to your product or misapplying the standards. Compliance rules can be complex – for instance, a company might assume their product doesn’t need CE marking when it actually does, or they might use the wrong standard (e.g., testing to an outdated version or a standard that doesn’t fully cover their product’s features). Another scenario is failing to realize that using certain components (like a wireless module) brings additional regulations into scope (like radio communications directives). These missteps can lead to non-compliance despite best efforts.
How to avoid it: Do thorough research and get clarity on requirements. At the start of the project, identify all applicable directives/regulations. If uncertain, check the European Commission’s guidance lists or UK regulatory guidance to see if your product category is covered. Consult official sources or standards databases to ensure you reference the latest harmonized/designated standards for each essential requirement. If your product is novel or borderline in category, consider seeking advice from a notified body or industry group about what standards/testing are expected. For example, if you have a IoT gadget, you likely need to comply with the Radio Equipment Directive (RED) in addition to general safety directives. Staying up-to-date with changes is also key: standards are updated periodically, and regulations can evolve (like the UK’s post-Brexit adjustments). Make someone on your team responsible for monitoring these changes or work with compliance experts who inform you. Essentially, avoid assumptions—verify every requirement. It’s much better to spend time up front clarifying what’s needed than to discover a compliance gap when you thought you were done.
The mistake: Viewing compliance as a one-time project that ends when you get the certificate or affix the mark. In reality, compliance obligations continue through the product’s lifecycle. A common pitfall is making modifications to the product after certification (for example, changing a component supplier, or adding a new feature) and not reassessing whether the product still conforms. Many companies have unintentionally voided their compliance by altering a design and not updating tests or documents. Another aspect is forgetting to maintain production controls – e.g., using cheaper materials in later batches that don’t meet the spec of the tested sample.
How to avoid it: Treat compliance as an ongoing commitment. After you obtain CE or UKCA marking, implement a process for change control. Any significant design change, material swap, or manufacturing change should trigger at least a review of compliance impact. Ask questions: Does this change affect safety? Does it introduce new hazards? Is retesting needed for any standard (for instance, a new PCB layout might need EMC re-check)? Keep records of changes and decisions made about compliance for each change. Also, maintain a relationship with test labs or certification bodies so you can consult them if unsure whether a change is “major” or not. Additionally, ensure your production stays consistent with the certified design – establish quality controls so that every unit produced meets the specs/standards of the prototype that was approved. Regular audits or inspections can catch if something in production starts to deviate. Remember that as the manufacturer, you are responsible for continuing conformity of the product as long as it’s being sold. A good practice is periodically reviewing your technical file and updating it with any changes, as well as keeping an eye on if any standards have changed, especially if your product stays on the market for many years. By doing so, you’ll avoid falling out of compliance over time.
Final Thoughts: Navigating CE and UKCA compliance can be complex, but steering clear of these common pitfalls goes a long way toward success. In summary, plan early, document thoroughly, test proactively, understand your requirements, and stay vigilant even after certification. Many companies that ran into trouble did so not because the rules were impossible, but because they underestimated some aspect of the process. By learning from these lessons and possibly leveraging compliance support services when needed, you can significantly de-risk the journey to getting your product certified. In the end, avoiding these pitfalls not only helps you get the compliance marks faster – it also improves your product’s overall quality and your team’s expertise for future projects.
