First time paying energy bills, should I be worried? 989kWh total energy use in a month.

I got my bill back from OVO Energy and they said from 11th Jan to 10th Feb I used 989kWh of energy for my last billing month, this amounted to £247. I rent a 2 bed flat with electric heaters & electric hob, no gas, I also work from home. Is this a normal expected amount or is something wrong?
