Up until recently I was a customer with Npower for over 3 years, the issue I had was my bills kept increasing yet my energy consumption was not. I received my final bill and to say I was shocked was an understatement! £346 due to my account being underestimated for over a year. No meter readings taken by an engineer for this time period nor any prompts from Npower for me to undertake them, quite frankly my account was obviously not being monitored. I have stated this in my official complaint however to no avail. I am now taking the matter further especially given that upon speaking to an advisor it was clarified that my gas meter has not had an inspection since 2016 therefore falling short of what is outlined by ofgem regarding suppliers licences, namely metres must be inspected every 2 years at least unless other arrangements had been made. In my case this was not and therefore due to the lack of concern regarding this and the lack of interest to try and resolve the complaint raised by myself I have no choice but to take this further with myself also preparing to take my case to the Gas and Electricity Marketing Authority. In addition to requesting all my statements showing the KW per hours used and the cost of the energy I have made a full subject data access request in addition to providing evidence of the metre inspection in 2016 and also the telephone recording from my conversation with the advisor regarding the matter. I must say I am disappointed that loyal customers can be treated like this and as a company you fall very short of what is expected in relation to customer care!!
