Onnec Awarded “Excellent” Rating by the Considerate Constructors Scheme

We are proud to announce that Onnec has achieved an “Excellent” rating from the Considerate Constructors Scheme (CCS) in a recent audit — a milestone that reflects our company-wide commitment to responsible construction, sustainability, and the wellbeing of our people and communities.

This recognition demonstrates our alignment with the Code of Considerate Practice, which sets standards in three core areas: Respecting the Community, Caring for the Environment and Valuing the Workforce.

What is the Considerate Constructors Scheme?

The Considerate Constructors Scheme encourages construction companies, contractors, and suppliers to operate with greater care for their neighbours, the environment, and their workforce. Each of the three pillars is assessed on a 15-point scale, with a score of 9 indicating compliance and higher scores recognising best practice and innovation.

Environmental Excellence: A Perfect Score
  • A key highlight of our recent assessment was a perfect 15/15 in the Environmental section, reinforcing Onnec’s reputation as a leader in sustainability within our sector. We were commended for our:
  • ISO 14001 accreditation, validating our effective environmental management systems
  • Strong controls over materials and waste at both our warehouse and head office
  • Adherence to all Principal Contractor (PC) requirements
  • Adoption of renewable energy initiatives at our head office
  • Active carbon reduction commitment with clearly defined targets and scope monitoring

Our approach aligns with our company values of curiosity, innovation, and continual improvement. We know that our impact goes beyond the build – and we’re committed to making it a positive one.

How We Achieved This

Achieving an “Excellent” rating under the Considerate Constructors Scheme was made possible by the collective efforts of our teams, and our proactive approach to building a better, more responsible business.

  • Sustainability in Practice: We’ve taken a forward-thinking stance on sustainability, underpinned by our carbon reduction strategy and ongoing investigations into innovative carbon-cutting methods specific to our industry. Our commitment to renewable energy and efficient resource usage supports our long-term environmental goals.
  • Effective Waste Management: Our central warehouse and offices are equipped with structured waste management systems, ensuring minimal environmental impact and responsible disposal of materials across all projects.
  • Supporting Our Workforce: We prioritise both the professional and personal wellbeing of our employees through clear policies and support mechanisms. This includes access to mental and physical wellbeing programmes, equality, diversity, and inclusion policies in place to ensure a welcoming environment for all and career development opportunities for internal staff and local job seekers, with additional support for disadvantaged groups.
  • Safety First: Health and safety is non-negotiable. We uphold the highest standards across every project with daily safety briefings, detailed RAMS (Risk Assessment and Method Statements) and a consistent focus on creating and maintaining safe working environments.
  • Leadership and Culture: Our open-door policy, championed by Directors and managers, ensures every team member feels valued and heard. We encourage collaboration, ownership, and shared responsibility in delivering quality work. Everyone is empowered to contribute to the successful delivery of projects.
Looking Ahead

While we are proud of this recognition, we know there is always room for improvement to ensure ongoing compliance and even higher standards moving forward.

At Onnec, we are committed to raising the bar for responsible construction — not just meeting expectations, but exceeding them. This “Excellent” rating is not just a score; it’s a reflection of our culture, our people, and our purpose.
