COVID-19 - update

The health and well-being of our employees, customers and suppliers are of paramount importance to us.

We continue to monitor the latest advice and guidance from the government and are working on measures across our business to minimise any future disruption which we may experience.

Motortronics has been deemed part of the “essential” business supply chain due to the industries and customers we serve.

We have a carefully restructured operation in place to ensure continuity of service and supply and will continue to ensure that we are following latest government & health guidelines to support the health and welfare of our staff worldwide.

Our staff are available via phone, email or video conference facilities in lieu of face to face meetings.

We are continuing to monitor the situation and should anything change a member of our team will be in touch directly. For more information click here for a statement from Motortronics’ Vice President – Joyce Mitchell.
