Earlier this month, Martin Lewis encouraged every energy customer paying their bills by Direct Debit to take a meter reading on the last day of March - just 24 hours before millions of households across the UK will see gas and electricity prices rise by 54 per cent.
The consumer champion said: “If you pay by monthly Direct Debit, I’d urge you to do a meter reading on 31st March, the day before the 54% rise in the April price cap.
“You need to draw a line in the sand with your energy provider, so that you’re saying ‘everything I’ve used up to this point should be charged the cheap rate’, rather than just letting it estimate what you’ve used in March and what you’ve used at the higher rate.”
