Due to long standing issues with Eon in 2007, I decided to change my supplier I was already a customer with British Gas, contacted them re supplying my Electricity, told them that they were already supplying my gas by way of a pre-payment meter, and that my electricity was also by way of a pre-payment meter. I was told i would receive notification of a change over date within a few days,I had received a letter from BG a few weeks earlier regarding a new tariff they had introduced in March 2007 it was called the "Essentials Tariff" and upon satisfying certain conditions afaer receiving the completed registration form BG would apply this new tariff. I returned the completed registration form, and then received a letter to say that they would be supplyiing my Electricity as from 25/08/2007, having received no key from BG, I was still using my old key, having contacted BG re my problem I was told a Key would be sent within a few days, but did not receive anything. I kept a record of all my the payments made on my old key, as from the 25/09/2007 up to and including 31/12/2007, I had credited £284 using my old key. during the dates stated. After issues regarding the amount I was crediting to my electricity BG informed me that they would be changing my pre-payment meter as from Sunday 3/02/2008. I had to contact BG 2 days after the new meter had been fitted as I had credited £19 in 2days and had a usage showing of 103.56 kwh ,it was suggested that I conduct a 7 day meter test after which I should contact BG with the results. I was shocked to find that from[midday] 03/02/2007 up to and including 13/02//2007, I had credited my meter with a total of £55 and had used a total of 421.33 kwh. I then recv'd a letter from BG dated 6/02/2007, the letter stated that Since 15th Jan a total of 776 kwh had been used presumably this was used from 15/01/2008 up to 03/02/2008 and was related to the old meter, this meant that in 19 days I had used 776 kwh, I had also noted that I had credited an amount of £284, from 25/09//2007 up to and including 31/12/2007. Upon telephoning BG with my results and concerns I relayed my meter readings to them , and that I stiil felt that the readings and figures I had, were quite excessive in comparison to other family members and companies, I was assured that the readings and figures given were correct. I then rcv,d a letter from BG dated July 2008, apologising for not updating my meter with the details for the "Essentials tariff" over the last few months, apparantley I had qualified for this tariff back in Feb 2008, but had been paying for the "Standard British Gas pay as you Energy tariff", an identical letter was also enclosed stating all details except it was for my electricity meter. Cutting a long story short.. Since Sunday 03/02/2008 up to and including 27/07/2012, I had been on the Essentials Tariff, which would end on the 27/07/2012, but a new scheme "Warm Home Discount Scheme" to register it required you to complete a form and return within 21 days choosing either "yes" or "no" for all questions,this I completed and returned on 26/06/2012, upon qualifying a discount of £130 would automatically be applied to your electricity meter before 31/03/2013. As from 27/07/2012 BG automatically moved me onto their "Standard Tariff" and details of the tariff had been printed on the back of the letter. "Standard Tariff" from 27/07/2012 up to and including 31/01/2013, I had noticed a vast difference in the amount of cash I was crediting to my meter after being moved onto the above tariff, I was discussing this with my daughter a few days before xmas, whereby she told me she had just received her £130 credit, I asked if she had noticed a difference with the amount she was crediting to her meter, which I discovered was nowhere near the amount I had been crediting. I decided to do a meter Comparison check with my daughters pre-payment meter, it was at this time I discovered that I had a lot more screens showing on my meter, than she did, after telephoning BG re my missing £130 discount, i was told that they had not received my form, and that it was now to late to obtain the £130 discount for 2012/2013, I stated that the completed form was sent to them, and that they also knew that I had been on Health Related Benefits since qualifying for the "Essentials Tariff" in 2007/2008, I was told there was nothing that could be done as the closing date had already gone. I then stated that I had been comparing my usage and costs with that of my daughters and found that I was crediting nearly twice as much cash to my meter and was also according to my annual statements using a great deal more electric. After relaying my meter readings to the BG operator, I was informed that I was actually on an Economy 7 meter and was also on a two tier rate, instead of the Single Rate, I stated that BG had installed the meter on 03/02/2008, and that i had contacted them 2 days after with regards to the amount I had credited within 2 days and after doing a 7 day meter check was told that it was ok. It was arranged that an engineer would call within 2 days and change the meter, but on arriving the engineer stated that the meter did not want changing as it was only the rate that needed changing, after the engineer had been took a reading immediately after he left and compared it to a reading i had taken just before he came. I decided to do a 7 day meter test once again, but after crediting my meter suddenly found that it had reverted back to the 2 tier rate again, after ringing BG again I was told that the engineer should have changed the meter completely, this was arranged to take place on 01/02/2013, once again I took a reading immediatelybefore the engineer came, and then did a meter check over the next 14 days. After comparing all my meter readings and annual statements for which I have 2 each year covering different months but same years [confusing i know] one statement stating next years usage [standard tariff] and the other covering different months but same year stating [essential tariffs], was told by BG they could not explain why this had happened, and that i was definately being billed for the essential tariff, I once again compared my readings against my daughters as she had been on the same tariffs as me but with a differnt supplier, I was appalled to find the following... New meter installed Sunday 03/02/2008, but instead of a Single rate tariff being used, I found that a 2 tier rate and night rate had been programmed onto the meter, this 2 tier rate and night rate was still in use up to and including 01/02/2013. After studying my readings from the meter I was shocked to find that since 03/02/2008 up to and including 01/02/2013, I had actually credited through my meter £5344, and had usage of 45251.05 kwh, the following is the actual reading immediatley before an engineer completely changed my meter..

Taking the annual figures of consumption and cost upon my daughters annual statement, here are the differences I noticed..... Daughters actual usage based on Actual readings from....

BG have been looking into this but have not contacted me as yet it was stated that BG calculation dept would calculate, what my usage was and the actual cost, but do not think I have been overcharged, can anyone help me on this matter before I contact them myself. Much Appreciated in advance junkimuki If there is Anyone out there that can actually work to the figures above, in relation to single rate and 2 tier night rate,
