For everyone else affected by the power cut, UK Power Networks sent the following:
Engineers are on their way. At this point we think the issue is a fault with some equipment in your local substation affecting the Farren Road, Como Road area. Until an engineer arrives on site, it’s difficult to give a time of restoration. Using an average timescale for this type of power cut in your area, we’re looking to have the power back on between 23:30 and 00:30 However, as the repair progresses; this may change.
