ABOUT LEIGH
Practical experience | Professional knowledge | A lifelong commitment to self-protection
"I’m Leigh Simms - a martial arts instructor, qualified non-practicing lawyer and author (#1 Best Seller on Amazon) specialising in self-defence law and self-protection training.
With over two decades of experience in karate and self-defence instruction, which includes achieving a 5th Dan in Karate recognised by the British Combat Karate Association, I’ve made it my mission to bridge the gap between effective physical techniques and the legal realities of self-defence in England & Wales.
My work empowers martial arts instructors, professional trainers, and frontline staff to teach and apply self-defence that is not only practical, but legally sound and professionally delivered.
I’ve authored on self-defence law, helped instructors audit their syllabus for legal risk, and now lead legally-compliant training programs trusted by martial arts schools, security companies, and corporate teams across the country.
Whether you’re running a dojo, managing a frontline workforce, or delivering CPD to high-risk staff, I help you remove legal grey areas, and train with clarity, confidence, and compliance."

Leigh Simms is as self-protection educator, martial arts instructor, and legal professional with extensive experience in training, teaching and knowledge sharing.
