Liniar Group: ISO 14001 Certification and Drone Surveying

ISO 14001

Liniar, a prominent player in the PVCu industry, has been manufacturing fenestration and outdoor systems since 1974.

Known for its innovation and sustainable practices, Liniar offers a comprehensive range of products, including windows, roofs, bi-folding doors, decking, and fencing. Their commitment to sustainability has earned them recognition and numerous accolades over the years.

Critical Path are complementary to our team, providing an external perspective for us. They have really understood and integrated themselves within our business and have done a fantastic job – I couldn’t speak highly enough of them!

The Challenge

Before engaging our services, Liniar held ISO 9001:2008 and ISO 14001:2005 certifications, along with a wide array of environmental policies, processes, and procedures.

With their purpose-built facilities in Denby, UK, Liniar understood the importance of continuously improving their environmental performance and sustainability.

However, they sought external support to conduct an impartial review of their operations and enhance their compliance efforts.

How We Helped

In 2016, we were appointed as Liniar's external support to facilitate the transition from the existing ISO standards to ISO 9001:2015 and ISO 14001:2015, the latest iterations. Our comprehensive consultation covered various aspects, including product lifecycle design, raw material handling, PVCu extrusion, packaging, warehouse management, and logistics.

To conduct a thorough environmental impact survey, we utilised drone technology, providing an aerial perspective and capturing hard-to-reach areas, improving safety and data collection efficiency. Additionally, we implemented improvement projects focusing on emergency preparedness, developing bespoke processes and procedures for spill handling, pipeline leaks, drill training, and on-the-job training.

Benefits of Drone Surveying

Enhanced safety: Drone surveying eliminates the need for personnel to operate in unsafe or hazardous environments, reducing potential risks and ensuring the safety of workers.

Aerial perspective: Drones provide a birds-eye view, capturing comprehensive and detailed aerial imagery of the survey area, including hard-to-reach or inaccessible locations.

Improved data collection: Drone surveys provide an entire recorded video or high-resolution images, offering a wealth of visual data for analysis and documentation purposes.

Cost and time savings: They are efficient, reducing the time required to survey large areas compared to traditional methods. This leads to cost savings by minimising labour-intensive processes.

Detailed site analysis: With drone surveys, it is possible to conduct a thorough analysis of the site, identifying environmental impact factors, potential hazards, and areas of improvement.

Environmental monitoring: Drones can be used for ongoing environmental monitoring, tracking changes over time and providing valuable insights for sustainable management practices.


Incorporating Environmental Documentation: Working alongside Liniar's internal compliance and environmental team, we integrated the environmental documentation into their ISO 14001 management system. This encompassed ensuring regulatory compliance, identifying site-wide environmental risks and opportunities, gathering relevant data, conducting environmental awareness training, and performing periodic internal audits and management review meetings.

Results Achieved

Collaborating with Liniar, we established an effective ISO 14001 Environmental Management System (EMS) that consistently manages corrective actions and environmental objectives. To maintain their certification, we conduct regular internal audits, while external verification audits are carried out by BSI, a renowned certifying body.

Even during the challenges of the COVID-19 pandemic, Liniar demonstrated resilience. They temporarily shifted production to manufacture protective visors for key workers, showcasing their commitment to community support. Despite supply chain disruptions, their ISO 14001 external audit with BSI resulted in zero audit findings for two consecutive years.

Our partnership with Liniar spans six years, covering a wide range of compliance and environmental consulting services. Through our collaboration and strong working relationship with the management team, we were honoured with a personal invitation to the company's internal staff Christmas party.
