I have a small company and we signed up in 2014 on a one year contract. Unknown to us the contract expired and our tariff shot up about 40%. They did not inform us we were out of contract. An ESB salesman called last month and gave us a cracking rate. He called because he could 'see' we were out of contract. The Energia bills fail to give the average or highest MIC used, as a consequence we were buying 125kVA MIC when our highest was 41 kVA. We paid Energia in excess of €10,000 in punitive tariff and ESB and Social in excess of €9000 for over stating our MIC. All could have been avoided with transparent billing. We are going to the regulator, but because it appears no wrong was committed, nothing will be done. Unjust enrichment? As close to a scam as you can legally go? Our office clerk would have to be very sharp to notice the tariff change amongst all the numbers. Avoid Energia!
