Electrical accidents, equipment failure, and downtime are often the result of inadequate maintenance or inspection practices. When a commercial or industrial business implements a good maintenance routine it can be extremely beneficial in order to maintain profits and minimize costs as a result of outages.

KER can offer maintenance contracts for all your electrical equipment or develop a preventative maintenance schedule for your own team to perform. We will inspect all your electrical components and diagnose potential threats before the situation becomes critical. Our maintenance programme is tailored to suit our customers’ individual needs depending on their sector and industry.
