Control, Operation and Maintenance

Our approach

At Electricity North West we are experts in dealing with high voltage equipment and will tailor our service to your particular system.

Under the cover of a Control, Operation and Maintenance Agreement, we will “adopt” your high voltage plant and equipment and treat it as an integral part of our own high voltage network. This will ensure your compliance with the Electricity at Work Regulations 1989 and all other associated legislation.
