I am delighted to have worked with Trinity on the MOD Corsham project. I needed a company that I could totally rely upon to meet the exacting requirements of the contract and I know from previous experience that Trinity delivers highly polished services as standard.

Sector Overview

The MOD (Ministry of Defence) is one of the largest land owners in the UK, with 230,000 hectares of land reflecting circa 1% of the total UK estate.

The current UK Defence budget is expected to top £45 Billion and highlights the ongoing investment required to support the Armed Forces right across the UK, including the construction and ongoing maintenance of the MOD’s buildings and residential facilities.

Trinity Sector Experience

Trinity Fire & Security Systems has gained a wealth of experience within the Defence sector over a number of years.

The Corsham PFI Development project, with a build value circa £194M, is a prime example of the typical works undertaken by Trinity on behalf of the MOD. The Corsham project is a military communications hub and the development provides crucial support for military operations around the world.

Trinity Fire & Security Systems completed the design, supply, installation, and commissioning of the 11-panel site wide networked Fire Alarm System and, in addition, a variety of Security Systems were also installed. Moving forward Trinity has also been chosen as the MOD’s preferred partner for their Planned & Preventative Maintenance.

Trinity is committed to providing the highest level of service and safety standards via the dedicated team of technical engineers based within our regional offices.
