About M3

Our Security Solutions

At M3 Security Systems we offer a wide range of systems to suit every need. We design, supply, install and maintain CCTV, access control systems, intruder alarms, fire safety systems, automated gates and other related products.


Led by Stuart May, the M3 team is small yet highly effective. Since our launch in 2005 we have established an enviable client base and a reputation for quality solutions and superior customer service.


From our HQ in Hampshire we work throughout South East England, including London and the Home Counties. 


Every security solution that we design and install is fully compliant with all relevant British and European Safety Standards. Our installations come with service and maintenance package options, and additional extended warranties for that extra peace of mind.


We tailor our systems to suit your requirements: whether you need a major commercial integrated system or a residential security solution we can help. With over 50 years combined experience in the security industry you can rest assured you will benefit from our expertise and dedication to delivering an excellent customer experience.
