WEATHER RELATED OUTAGES - updated 1.00pm 27/10/2025

We’re making great progress restoring power across the network. Currently there are 178 customers without power, but we have a large number of crews in multiple locations again today.

We are keeping a close eye on the developing weather system. Unfortunately some of the repairs require helicopter assistance and these will have to wait until the weather has moved through.

Estimated restoration times are regularly being uploaded to the Outage Map.

If you have any concerns or questions, please call our customer service team on 0800 30 90 80.

TREAT ALL POWER LINES AS LIVE AT ALL TIMES. Please stay away from any downed lines and report any sighting to us on 0800 30 90 80.

For the most recent updates on outrages, please check our outage map. To report an outage, call 0800 30 90 80.
