A massive power cut forced shops, offices and units in Sussex to close down as more than 1,500 customers of UK Power Networks were affected. A spokesperson from the company apologised for the incident after swiftly restoring power, and added: "UK Power Networks worked as quickly and safely as possible to restore power to 1,574 customers in Horsham, whose supplies were interrupted…following a fault on the high voltage electricity network." The fault was due to an explosion at a nearby electrical sub-station.
