2007
The year Dalex Systems was established. It has continued to grow ever since.
Today we operate a range of building services, with a growing number of office staff and a qualified, highly experienced all-trade base, including multi-fuel heating engineers and builders.
Our approach, to be the complete "one stop shop" for all central heating services, has developed continuously. It is constantly reviewed with one aim: to surpass our clients' expectations.
As a company we have the structure, capacity, experience and resources to deliver a quality service to suit every customer's requirements.
