2D Building Contractors achieves ISO certification to strengthen tender credentials and support business growth.
2D Building Contractors, based in South Wales, specialises in refurbishment and planned maintenance across the commercial sector. With ambitions to grow and secure more prestigious contracts, the company recognised that ISO certification could play an important role in demonstrating professionalism, strengthening internal processes, and supporting participation in public and private sector procurement.
Like many growing businesses in the construction sector, 2D Building Contractors reached a pivotal stage in its growth journey: how to access higher‑value contracts and build confidence with larger clients.
While the business had strong operational capability, it lacked a recognised way to demonstrate quality, compliance, and health and safety performance – particularly where certification to ISO standards was referenced or expected within competitive tenders. With limited prior experience of certification, the business sought a UKAS‑accredited certification body with a clear, structured process that would not disrupt day‑to‑day operations.
After conducting independent research, 2D Building Contractors selected British Assessment Bureau (part of Amtivo Group), based on its UKAS accreditation, transparent certification process, and strong client feedback.
The business successfully achieved certification to the following ISO Management System Standards:
These standards provided a structured approach to aligning internal management systems with recognised best practice. Implementing an Integrated Management System helped the business establish clear structure and consistency, while maintaining ownership of its internal processes.
From the outset, 2D Building Contractors valued British Assessment Bureau’s clear communication and structured certification process. The onboarding experience was straightforward, and the online client portal made it easy to access documentation and track progress at each stage.

All of the instructions received were very straightforward… The integrated manual provided us with a solid backbone to structure our evidence and processes, leading us methodically through our company systems.
