ISO certification in the construction sector

The ISO standards are well known within businesses who operate in the Construction industry. Qualifying for tenders and government tenders is one of the most important objectives of a Construction company. Gaining ISO certification can help this as it demonstrates that appropriate procedures and processes are in place to meet objectives efficiently and consistently.

Why Do Construction Companies Need ISO Certification?

The construction industry is one of the few sectors which expect ISO certification as a minimum entry. Companies who are not ISO certified may get left with the smaller jobs and therefore struggle to grow. A key requirement when going for tenders is to showcase appropriate Management Systems which will drive improvements. Additionally, for construction companies to streamline operations, it is important that they have the right Management Systems in place which work with their scope. Becoming ISO certified covers different operations and helps develop an effective Management System. 


ISO 9001 is the minimum required standard for most construction companies who are looking to expand. This will demonstrate a solidified quality management system and quality of work carried out to customers. The natural progression from ISO 9001 is ISO 14001. This ensures environmental impacts are considered, which is massively important for construction companies. As regulations and environmental controls are constantly changing, companies will need to keep up to date with the ISO14001 standard to ensure all requirements are met. From this, ISO 45001 is introduced. This is the standard for ensuring a Health and Safety management system is implemented. Achieving ISO 45001 develops trust with a company’s clients, employees and contractors. Due to this, many construction companies will select sub-contractors based on their Health and Safety performances. Also, being able to actively demonstrate this will bring success to your business.

Considering Construction is one of the most dangerous sectors to work in, ISO certification is vital for Construction companies to possess. As a result, ISO 45001 is key as it is a major factor in controlling and reducing the number of accidents which occur. Another point to consider is that being ISO certified will also demonstrate the company is working hard towards continual improvement. This is desired by stakeholders and tenders. 

ISO 9001, ISO 14001 & ISO 45001 are some of the most important ISO certifications which will help Construction companies. 


ISO9001 will help organise and manage subcontractors with the appropriate procedures and policies being implemented. ISO 14001 will help gain a deeper understanding of the environmental impacts construction has. By managing this, benefits including reduced waste and management of energy will be presented. Gaining ISO 45001 will demonstrate understanding of health and safety measures in the workplace. Therefore, reducing the risk of incidents and accidents. Which helps improve trust between employees, stakeholders and suppliers.

We have developed two pathways for ISO certification. Internally managed and supported by consultancy. This means that you can achieve certification in whichever way suits your company and current Management System. Our consultants have extensive experience in the ISO world and will be there to support you through the ISO journey. All requirements of the ISO standard will be in place and thoroughly checked prior to your external assessment.

The Cost of consultancy is very much dependent on the size and scope of your company. We will always offer a free visit to assess your company’s requirements and provide a no obligation quote based on this initial assessment together with an estimated completion date.

If we implement The Titan System, we will set up a fixed monthly subscription fee on a flexible rolling contract. Prices for both are available on request here.

Testimonials from construction clients

Working within the utilities industry and competing with large tier 1 consultancies where ISO accreditations are the norm, WorkFlow Services decided to start the ISO journey to gain ISO 9001 accreditation. After meeting with Mark Nolan and the team and seeing the Titan software in action, WorkFlow were confident that not only could they gain 9001 but also decided to work towards gaining 14001 and 45001 too. Having little knowledge of the requirements at the start of our journey, Mark 1 have enabled us as a company to learn and develop our systems and create an IMS.

WorkFlow Services have now completed their Stage 1 audits for all 3 certifications and are about to go through the stage 2 audits from which they hope to gain official certification next month. This is thanks to Mark 1 and their knowledge and invaluable help along our journey.

Jane Gough - Workflow Services Ltd

Our business is dependent on robust processes and outstanding products so it was natural for us to seek ISO accreditation. Working with Mark 1 gave us the direction and support we needed to achieve the standard. We are dedicated to sustaining this now and building on this success

Brian Lee - Managing Director

It was a rigorous process however Mark 1 provided excellent guidance and support from start to finish and we are absolutely delighted with the outcome. We have now achieved status in both quality and environmental management which enables us to expand our client base as the certification is a necessary requirement for many customers, in particular those working within the public sector.
