About OSI

Ethos

Delivering high quality projects

The Directors and many of the managers, supervisors and trades staff have worked together throughout the life of the company. We have developed an ethos of working together that is efficient, cost-effective and positive towards the local environmental , diversity and sustainability considerations.

Almost 30 years of quality

The company was formed in 1982 initially to service the growing market for specialised main-frame computer environments. This work demanded fast-track, multi-disciplined teams experienced in the design and installation of power supplies and climate control in addition to the entire range of internal systems and finishes.

” OSI now applies this ‘one-stop-shop’ approach to all types of property refurbishment and fitting out. We combine general and specialist skills with in-house building services resources to provide an integrated and reliable high quality service.”

We work throughout the UK and Overseas with all projects supervised by a Director with full decision-making responsibility. OSI is committed to providing a first class service, one where time, quality and overall client satisfaction are our key concerns.
