We are built on trust: our accreditations and memberships
Trust is what we are built on – our accreditations and memberships
At IDH, engineering excellence is more than just a goal; it’s built into everything we do. That’s why we hold ourselves to the highest standards through a range of respected accreditations and memberships. These aren’t just badges on the wall, they’re an important part of our culture, guiding how we think, work, and deliver across every project.
Our certifications and membership certificates help us stay accountable, safe, innovative, and client focused. You can view our current certificates by clicking on each logo.
Quality isn’t an add-on at IDH, it’s our foundation. ISO 9001:2015, the internationally recognised quality management standard, gives us a robust framework for consistent delivery and continuous improvement. It ensures our processes remain sharp, adaptable, and always evolving, so our clients get the best, every time.
Constructionline Gold and Builders Profile
As Gold members of Constructionline and verified on Builders Profile, we make it simple for clients to assess our credentials quickly and with confidence. From health and safety to financial stability, our pre-qualified status speeds up procurement and reassures clients that we’re ready to deliver from day one.
Once For All Health & Safety SSIP (SSIP Acclaim)
Our Acclaim accreditation via the SSIP framework speaks volumes about our safety-first approach. We don’t treat health and safety as a box-ticking exercise. Whether for temporary works or permanent structures, we prioritise safe outcomes across the board.
Working in the rail sector demands rigorous compliance. Our RISQS verification proves we’re up to the challenge. It confirms we have the expertise, systems, and processes to design safe, effective, and regulation-ready solutions for complex rail environments –helping to keep the UK’s railways running smoothly.
Safety and well-being are non-negotiable at IDH, particularly in the rail sector. Our membership with CIRAS (Confidential Incident Reporting and Analysis System) gives our rail team a safe, confidential space to raise concerns. It strengthens our culture of openness, accountability, and continual safety improvement.
In an increasingly digital world, safeguarding data is a critical part of all businesses. Our Cyber Essentials certification proves we have the necessary controls to protect against common cyber threats. Whether it’s sensitive client information or technical documentation, we treat data with the utmost care.
Institution of Civil Engineers (ICE)
Our people are our greatest asset. That’s why we’re proud to have chartered and incorporated engineers on our team, registered with the Institution of Civil Engineers. As an ICE approved employer, we go a step further, actively supporting our engineers’ development through structured training and mentoring, so they continue to deliver excellence at every stage of their careers.
ICO Registered
We’re committed to responsible data management. Being registered with the Information Commissioner’s Office (ICO) confirms we comply with UK GDPR and approach data handling with integrity. It’s just one more way we show our commitment to doing things properly.
As members of the Temporary Works Forum (TWf), we stay informed on the latest guidance, innovations, and risks in temporary works. This insight shapes how we design scaffolding, formwork, falsework, and hoarding; so that temporary structures are safe, efficient, and built on current best practices.
Scaffold design requires precision, safety, and practicality. We follow guidance from the National Access and Scaffolding Confederation (NASC), the industry standard-bearer for safe and compliant access solutions. It’s a benchmark that ensures our designs are ready for any challenges.
As members of Construct, we stay at the forefront of concrete technology and design. It keeps our engineering fresh, relevant, and aligned with modern construction methods, that way our clients benefit from the latest thinking in concrete solutions.
Holding a Builder’s Profile certificate means IDH can manage building safety risks, maintain proper records and demonstrate organisational competence.
The Building Safety Act (BSA) Standard Construction Assessment is a construction industry assessment used to demonstrate that a company complies with the UK Building Safety Act requirements and has the appropriate competence, processes, and safety controls in place.
We’re proud to share and report on IDH’s annual carbon usage, which we do through the Supply Chain Sustainability School. We’re committed to transparency and sustainability. This initiative allows us to engage with our partners and stakeholders, taking a collaborative approach towards a more sustainable future.
At IDH, these accreditations and memberships don’t just validate our work, they strengthen it. They help us maintain high standards, encourage continuous improvement, and foster a culture where safety, quality, and innovation are second nature.
For our clients, it means every project is underpinned by robust processes, talented people, and a trusted reputation, so you can build with confidence.
Certified. Trusted. IDH.
