As the energy price cap comes into force on April 1, people are being urged to submit their energy meter readings before the costs spike.
Today has been dubbed 'Meter Reading Day' as bill payers scramble to get their energy usage submitted before the 54 per cent rise.
However with the amount of traffic that energy companies have had online has led to Octopus Energy, EDF, E.ON and SSE crash, leaving customers unable to submit their meter readings. British Gas customers have had this issue since February.
