Manx Utilities headquarters will only be open to customers for key meter readings from today.
The authority is making changes to how it operates as a precaution against the Coronavirus outbreak.
The organisation says its teams will be working remotely to respond to emergency fault situations.
It adds for any business other than key metering, customers should visit www.manxutilities.im, call 687 687 or e-mail enquiries@manxutilities.im
