YY Security was originally established in 1948.

By the late 1980’s early 90’s with the help of new directors YY Security had expanded to a London and nationwide security company, providing a complete residential and commercial service.

With Steve Owens as the current director, with 30 years + experience, the company has moved from strength to strength and is constantly improving and advancing services.

Having procured the London underground contract in the 80’s, amongst several other high profile contracts, YY Security continued to adapt to an ever changing security industry encompassing:

  • Locksmiths
  • Burglar Alarms
  • Access control
  • CCTV Glazing
  • Fire Alarms
  • Grilles & Gates
  • Carpentry Security
  • Security Shutters
  • Automatic Gates

Having invested considerably both in terms of time and finance into ensuring that our policies and operating procedures are of a British recognised standard, we are very proud to say we have been awarded ISO 9001 2008 and with an unprecedented view point to health & safety/environmental issues, Young & Young are moving towards an ISO14001 certification.

Shane D’Moirah became a director of Alarms/CCTV/Access Control in 2001 and has driven the company forward in new technology advancements including meeting the stringent requirements of the industry by SSAIB (Security Systems and Alarms Inspection Board).

This body being UKAS Accredited – Registration No: 131-A. SSAIB is a leading Certification Body offering a wide range of schemes for providers of electronic security, fire systems and guarding security services in the UK and Republic of Ireland. Their aim is to promote high standards within these sectors and to provide recognition for those who achieve them.
