Real feedback from organisations certified to ISO 19443 by LRQA.

Achieving ISO 19443 certification reinforces Balfour Beatty Kilpatrick's commitment to placing nuclear safety, quality and continuous improvement at the heart of everything we do. The standard has strengthened our nuclear safety culture, enhanced supply chain assurance and provided independent confidence to our customers and stakeholders that robust controls are embedded across our business. We chose LRQA as our certification partner because of their recognised expertise within the nuclear sector and their professional, collaborative approach throughout our certification journey. Achieving certification with zero nonconformities is a testament to the commitment of our people and leadership team across the organisation.
Balfour Beauty
As a long-standing supplier into the nuclear sector, ISO 19443 certification is essential to demonstrating to our customers that quality and safety are embedded throughout our supply chain and internal processes. The nuclear safety culture embedded within the standard has had a positive impact on the wider business, generally improving operations and conformance throughout. Achieving certification has helped us strengthen our internal processes, improve traceability, and give our nuclear clients greater confidence in our ability to meet their exacting requirements. LRQA have been our trusted certification partner for many years, and their understanding and guidance of the ISO 19443 standard was hugely beneficial in achieving certification.
Brafe Engineering
ISO 19443 is an important milestone for Broder Metals Group, demonstrating that our quality management systems are designed to minimise risks that could impact nuclear safety while meeting the stringent expectations of the nuclear supply chain. Certification has enabled us to engage with customers who require ISO 19443 as a prerequisite for tendering, supporting our growth within the sector. With major projects such as Great British Nuclear SMR programme, Hinkley Point C and Sizewell C driving demand for qualified suppliers, we are proud to be among the first UK bar stockholders to achieve this internationally recognised standard. LRQA's technical expertise and collaborative approach continue to support us in maintaining and continually improving our management system, ensuring we consistently meet the high expectations of the nuclear industry.
Broder Metals Group Limited
We found LRQA to be a trusted and collaborative partner, and their support was instrumental in helping us achieve certification. We would like to thank the LRQA team for their expertise and contribution to this successful outcome.
CEF
As a supplier within the nuclear sector supply chain, ISO 19443 helps us ensure that our quality performance aligns with the high standards expected within the industry. Cyclife has a nuclear-licensed site, and ISO 19443 assists us in managing our supply chain and in assuring predictable, desirable quality outcomes.Cyclife UK has only been certified since 2025, so it is a little early to realise all the anticipated benefits. However, better supply chain controls and an improved competitive position are two very clear benefits that have manifested quickly.LRQA is a UKAS-accredited, reputable organisation with whom Cyclife UK has a long-standing, mutually beneficial relationship. LRQA provides consistently good service and a high calibre of auditing personnel, all of whom are trained and deliver in a consistent manner to a high standard. 
Cyclife UK
With the Nuclear sector set to grow in the coming years ISO 19443 was a natural progression for us. Goodman Metalworks are already heavily involved in Oil & Gas and Nuclear fabrication & welding so the Quality Systems were already in place, we just needed to build on top of the solid foundation we had. The standard itself sets a very high bar but working alongside LRQA has been a seamless process and the auditors have been knowledgeable and precise. We were proud to achieve certification at the first attempt and sail through SV1 with no Minor NC's.
Goodman Metal works
Achieving ISO 19443 certification represents an important milestone for Jay Contracts Ltd and reinforces our commitment to quality, traceability, risk-based thinking, and continual improvement.Implementing the standard has strengthened our management systems and enhanced our ability to meet the demanding expectations of the nuclear supply chain, while embedding greater awareness of nuclear safety culture throughout the organisation.We chose LRQA because of its recognised technical expertise, professional approach, and ability to provide a robust and credible certification process.

Achieving certification has strengthened our processes and provided greater confidence to our customers and partners. We chose LRQA as our certification partner for its expertise, credibility and understanding of the specific quality requirements of the nuclear industry.
SIG Trading Ltd
Attaining certification to ISO 19443 was significant for STRABAG UK Ltd, as it verified that we have the arrangements in place to deliver projects and services that are important to nuclear safety, indicating to clients and regulators that we are a capable supplier.
Going through the certification enabled us to enhance existing arrangements for the benefit of not just nuclear related projects, but also projects in our current sectors, namely transport infrastructure, energy, light industrial and water. It also helped to strengthen awareness of requirements for nuclear related project delivery and nuclear safety culture across the business.
Working with LRQA has validated the reason for choosing them to undertake the certification, as they were proactive, explained what was needed and the assessors were knowledgeable and experienced on both the ISO requirements and nuclear projects.
