At WL Straughan & Son Ltd we are committed to the safety of both our personnel and for all those around us. RAMS (Risk Assessment and Method Statements) are produced for every single job. This approach allows us to highlight all possible risks and make sure everyone on site is kept safe, accounted for, and secure. 

Health and Safety is at the centre of everything we do. Our policies and procedures cover all aspects of our work and are supported through our regular management meetings and training sessions. 

Proof of our commitment to safety can be seen by our certifications, which include:
