Who We Are
A UK Commercial Security Specialist, Established 2006
Founded in 2006 by a BSc (Hons)-qualified network engineer, MCD Security Systems has grown into one of the UK's trusted commercial security specialists — delivering CCTV, access control, intruder alarms and security consultancy for clients across the commercial, public sector and international markets.
Over 17 years and 1,000+ installations, we've built our reputation on technical expertise and a relentless focus on project delivery. Every system we install is specified by experienced consultants, installed by CRB-checked engineers, and backed by a 2-year workmanship warranty and ongoing support.
From a single access-controlled door to multi-site, fully integrated security solutions, our approach is the same: understand the risk, design the right system, and deliver it to specification.
"This is why organisations across Yorkshire, London and beyond choose MCD for their security and consultancy needs."
