Thanks for posting and welcome to community
I am very sorry that your payments have been increased by such a lot since you started with us, especially given that you input your estimated annual usage upon signing up. Your payments have been increased in order to pay back the debt in your account, which was caused by your payment initially being too low compared to your usage.
I’ve had a look over your statements and the majority of your usage does seem to be on electricity. Do you have any really old appliances in your home, or have you bought anything extra?
It might be worth testing your meter to check whether it’s clocking usage correctly. You can do this yourself. All you need to do is to take a photo of your electricity reading and then turn off your electricity supply at the fuse box. Then, at least 30 minutes later, take another photo of the reading. The number shouldn’t have changed, as there was no electricity going through your meter. So, if it has, then your meter could be faulty. Let us know once you’ve done that test and we can take it from there.
With regard to your first generation smart meter, I’m sorry that we’re not yet able to get remote readings. We are hoping to enroll all smart meters like yours before the end of the year, and we’ll email you once this is possible.
Any questions, please let us know.
