Snowdonia Global Safety Services Ltd is a specialist health, safety and environmental consultancy founded by John Frost, delivering expert support across complex, high-value construction projects worldwide. With over 25 years of experience in high-risk industries, we provide strategic HSE leadership and practical on-site delivery to ensure projects are completed safely, efficiently and in full compliance with regulatory requirements.

Our experience spans major international developments across data centres, nuclear, oil & gas and pharmaceutical sectors, supporting both clients and principal contractors on multi-million and multi-billion pound programmes. We are trusted to embed safety at every stage of the project lifecycle—improving performance, strengthening safety culture and ensuring successful project delivery in demanding environments.

Our consultancy is built on a foundation of real-world project delivery at the highest level. We bring extensive experience working on complex builds in highly regulated environments, where safety, precision and performance are critical.

We have successfully led HSE strategy and delivery on large-scale developments including hyperscale data centres, energy infrastructure and pharmaceutical facilities. This includes managing multidisciplinary teams, advising senior stakeholders and working collaboratively with global clients and contractors to achieve exceptional safety outcomes.

Our approach combines technical expertise with strong leadership, enabling us to influence behaviours at every level – from boardroom decision-makers through to site operatives. We are experienced in implementing ISO 45001 systems, ensuring CDM 2015 compliance and driving continuous improvement across all aspects of health, safety and environmental performance.

At Snowdonia Global Safety Services Ltd, we go beyond advisory services. We provide practical, solutions-driven support that delivers real results. We understand that every project presents unique challenges, particularly in high-risk and live environments, and we tailor our approach accordingly.

We specialise in identifying risk early, developing effective mitigation strategies and implementing robust safety systems that integrate seamlessly into project delivery. Whether it’s complex MEP interfaces, high-voltage systems, confined space operations or logistics within operational facilities, we provide clear, actionable solutions that support both safety and productivity.

Our focus is always on enabling progress, not restricting it, ensuring that safety becomes a driver of project success rather than a barrier.

At Snowdonia Global Safety Services Ltd, we combine technical expertise with a collaborative and commercially aware approach. We work closely with clients, principal contractors and supply chains, integrating seamlessly into project teams and delivering value from day one.

We understand the pressures of programme delivery, budgets and deadlines, ensuring our safety strategies support progress rather than hinder it. Our clear communication at all levels helps maintain consistency and confidence throughout the project lifecycle.

Beyond compliance, we focus on building a proactive safety culture through behavioural programmes, coaching and engagement. This approach drives improved performance, stronger workforce wellbeing and measurable reductions in incident rates across high-risk, complex projects.
