Company Profile

TSI - Total Security Installations - is a long standing security company with over 40 years industry experience.

In the early days, TSI specialised in safes and vaults. Founder and chairman, Peter Terry, invented the Terry anti-hold-up Safe back in 1972. Over 40 years on you will still find it in use, protecting cash and staff. A product still approved by insurers today.

As customer needs developed, so did TSI, diversifying UK-wide and offering both physical and electrical security solutions. Along the way, we've kept our customer focus, family-run ethos and commitment to quality and innovation.

Today, our expertise is at the forefront of the business.

Our award-winning staff who have technical ability and product knowledge, blend with industry professionals within our team, including former heads of security and loss prevention experts, from insurance, retail and finance.

Applying this knowledge has earned TSI an international reputation for innovative, bespoke engineered solutions.
