Which Industries Require The ISO 9001 Certification?

Ensure your business meets the highest standards of quality assurance

While there is currently no legal requirement to receive accreditation from the International Organization for Standardization (ISO), there are many sectors where businesses are expected to do so.

Despite the ISO 9001 Certification not being mandatory on a national level, the most lucrative tenders offered by both public and private clients are frequently only awarded to companies who can prove they meet this standard. In some cases, it is specifically requested, while in others it remains an unspoken preference. Any industry revolving around production or customer service faces particular scrutiny of their working practices.

These examples highlight the significance of the ISO 9001 Certification for securing contracts in these sectors:


Due to the complexity and costs associated with construction work, prospective clients will often request proof of robust Quality Management System (QMS). While businesses can offer informal assurances of their working practices, clients are most likely to trust externally audited certifications like the ISO 9001.

It is seen as a guarantee that the contractor doesn’t have to worry about checking in on the site at every stage, as the business will necessarily have excellent training and safety processes in place for every worker. The certification also shows a commitment to sustainable products and practices, which investors will be looking for to ensure their buildings stay in top condition and retain value for years to come.


For manufacturers, it’s particularly important to provide evidence that their operations are subject to detailed quality management. When deciding where to award a tender, clients want to focus on the tangible product, without having to assess the manufacturing facilities of individual bidders. In these instances, an ISO 9001 is seen as a key indicator that a business is adhering to the highest international standards of production methods, facility management, and quality assurance checks. It also increases confidence in the manufactured goods, as there is a proven correlation between ISO-approved strategies and durable end products.


The hallmark of an excellent hospitality business is a positive experience for the customer. For the customers themselves, this may seem like a straightforward process reliant on the employee they encounter at the point of delivery. The reality is that a whole host of training, coordination, and management takes place behind the scenes to ensure smooth outcomes. Contractors are aware of this and seek proof of standardisation as a guarantee that service will remain consistent, even when potential difficulties arise.

The ISO 9001 Certification signals that every stage of delivery has been subject to a QMS, and that a business will continue to develop their service in response to the changing needs of customers.


There are many conditions that healthcare providers must consistently meet in order to remain in business. These have relevance at every level of an organisation, from specialised medical procedures to waste management. Monitoring the compliance and customer experience in every department requires thorough quality management, with adequate training and support across the company. The most efficient businesses look to the ISO 9001 for guidance in setting up a QMS that works for them, keeping in mind any legislation and other ISO standards they must adhere to.

Whether the potential customer is a contractor or an individual patient, the nature of the industry means that there may only be a short window to secure the client. In these instances, proof of ISO 9001 Certification can be provided immediately, establishing confidence in all areas of healthcare provision.
