To celebrate many years of success the company gained Limited Company status in April 2014. Since its inception the company has moved from strength to strength.

In early 2017 the addition of an “In House” Design and Survey Office has seen the Domestic Extension/Orangery Business significantly expand. This allows us to reduce planning costs for clients and suggest cost effective methods from the start. It has also enabled us to provide “Smoke Evacuation” and ventilation expertise to our commercial base.


Also in 2017 Certass registration has also moved on the replacement Window/Door sector with a big increase seen in the Bi folding door market. This allows Complete Installation Systems Ltd to deliver Building Regulation Certified compliant glazing, with the added protection of Insurance backed Guarantees to all our clients, in Pvcu, Aluminium and Natural wood finishes.
