With headquarters in Nottingham and a further office in Watford, we are a national organisation, able to deliver our services across the UK. We also have a strong track record of working overseas and have a large network of partners across the globe who work with us to deliver our services internationally.

QSG traces its roots back to the early days of electronic security when we were pathfinders in the development of CCTV and security systems. Our company ethos is based on customer excellence and we pride ourselves on delivering excellence in all we do. This is validated by our enviable track record in retaining our customer base with some of our customers remaining with us for over 30 years. The same can be said of our highly qualified team of people; the majority of which have been in the security industry all of their working lives and spent that time working for QSG.

Our core business is delivering cutting edge, complex, security systems to public and private sector organisations. We do this by directly employing the top industry experts in the field of system design, project management and engineering. Our customer offer is completed by our national service division which provides ongoing service management.
