Energy suppliers Octopus and Shell have given an urgent message to customers who were unable to submit their meter readings on March 31.
Energy websites crashed yesterday morning after hundreds of people logged on to give them their meter readings ahead of April 1 when the new energy price cap comes into force. The day has been branded 'Bleak Friday' as thousands are expected to fall into fuel poverty by October.
Experts including Citizen's Advice and Martin Lewis have been urging people to submit their meter readings on March 31 to "draw a line in the sand" before the price hike.
