I’ve had a similar issue after a new meter was installed without proper notice. Just like you, my electricity usage jumped by over 30% even though nothing had changed in my household — same appliances, same routine. I also suspected the new meter might be reading inaccurately, so I tested my usage with minimal load, yet the readings remained high. It’s frustrating to see billing escalate when your actual consumption hasn’t. Installing an independent usage monitor in your DB board can really help cross-check the readings before escalating the issue to your power company. In my case, I noticed an unusual spike in my MEPCO bill after a new digital meter was installed. I documented the issue and shared more details here for anyone facing the same problem: https://mepcobillchk.pk/ .
