We've only had a prepaid meter in our house for 4 months now and we are a household of 4 adults. We have noticed that the electricity usage is now reaching the levels of billed electricty. I'm aware of the sliding scale but heck, we are basically back to where we were before prepaid. As yet we have not even switched a single heater on and our pool pump is down to 4 hours a day. We use an energy saving lamp in the lounge instead of using the main lights in the evenings. We deduced that switching the geyser off-and-on really had negligible impact, so we stopped that and as surmised, the impact was hardly significant. We are at R200 per week now and at this rate we will soon be back at our pre-prepaid levels.
So really, does it actually save you money, or does it work on the idea that if you visibly see your electricity burning up, you become el cheapo?
