Onnec Achieves Perfect Score in Considerate Constructors Scheme Audit – 45/45
Onnec is proud to announce that we have achieved a perfect score of 45/45 in our most recent Considerate Constructors Scheme (CCS) audit for our UK office. This represents our highest ever performance and has contributed to an uplift in our overall Certificate of Performance, rated “Excellent”.
The result reflects excellent levels of conformance across the CCS Code and confirms that we have effectively addressed the improvement opportunities identified in the previous office review. Site validation meetings undertaken during the latest registration period also confirmed that our policies and procedures are being consistently implemented across our sites.
The audit recognised our strong performance across all areas, including construction promotion, community engagement, environmental management, and workforce wellbeing, alongside our ongoing commitment to Net Zero.

Respect the Community – 15/15
We actively support principal contractors in delivering community-focused initiatives and site rules, ensuring we maintain a professional presence while delivering extensive community engagement and construction promotion activities.
Care for the Environment – 15/15
Our environmental management systems are ISO 14001 certified, with strong alignment to all principal contractor requirements. Environmental awareness is embedded through inductions and toolbox talks, while waste, energy use, water consumption, and logistics are closely monitored as part of our wider carbon and Net Zero commitment.
Value their Workforce – 15/15
Health, safety, wellbeing, and inclusion remain central to our culture. We are progressing towards ISO 45001 certification and continue to invest in high-standard wellbeing provision and a strong focus on Equality, Diversity and Inclusion across the business.
We are absolutely delighted with this result. Achieving 45/45 is no small feat, and it speaks volumes about the culture we are building across Onnec – one that prioritises responsibility, collaboration, and continuous improvement. A huge thank you goes to the entire team for their dedication and commitment in helping us achieve this outstanding standard.
