Who we are
Health & Safety Advisor.co.uk (HSA), powered by Lesu, is an owner led UK health, safety, quality and compliance consultancy, built and led by experienced, chartered professionals. We act as the competent person for businesses that need expert safety advice without the overhead of a full in-house safety department.

John Turner
Founder and Managing Director
A welcome from John
Thank you for visiting. I started this business because I believe every organisation deserves safety advice that fits them, not a template. When you work with us, you work with me and my senior team directly, and we build everything around your people, your sites and your goals.
Our vision
To be the health and safety partner UK businesses turn to first, because good safety advice should be personal, practical and built around you.
What makes us different
We don't sell packages. Every client gets bespoke, customised support, scoped to your risks, your sector and your people, then delivered by the same senior specialists from first call to close-out.
Our four Cs
Meeting the law and the standards that apply to you, clearly and confidently.
Building safety into how your people think and work every day.
Plain, honest advice that everyone on site understands.
Reviewing, learning and raising the bar, project after project.
Our people
Health & Safety Advisor.co.uk is owner-led. Engagements are partner-run from enquiry to close-out. Specialist consortium members are utilised as per SQEP requirement.

How we work
Everything we do is guided by our four Cs: Compliance, Culture, Communication and Continuous Improvement. Every engagement is bespoke, because lasting safety comes from working together, not box-ticking.

Supporting the Armed Forces community
We proudly support SSAFA, the Armed Forces charity, which provides lifelong support to serving personnel, veterans and their families. We value the skills and discipline that service leavers bring to health and safety.
