Unusual usage amount

My laters monthly bill is approximately double my usual which is strange since I have turned off heating in half of my house. Where can I query a usage calculation?

Is the bill based on actual meter readings?

Hey @Dagurney

Thanks for your post, in feb you gave us a set of reads a day after your estimated bill which was over 700kwh higher than expected. This was the first read since November so indicated you had used a lot more than we estimated for the winter period.

We would suggest adding reads each month from now on to prevent shock bills.
