See attached for the bill including lots of scribblings from me! Remember the new meter fitted on 17/12 should start at 376 and 1855 rather than zero. I understand the standing charge - was just not paying attention sufficiently when I looked at the costs per unit earlier! S45C-311021116340.pdf

it's a spooky coincidence! Old meter was from 9/8 to 17/12 and then new digital one was from then to 2/2. Reading 1 is the day rate and Reading 2 is the night one. Am not at home though so can't have a look at it right now but will hopefully remember to do so when I get back from work. Looking at the amendments I've made to the wrong bill, I was incorrect earlier - the night rate is of course cheaper than the day one so I seem to have somehow been advantaged if this meter is measuring incorrectly! Mistake i made earlier was due to the fact they included the standing charge on my night costs. Night cost per kWh is 4.1p and day is now 10.82p.

yes something is odd isn't it? Splitting my bills into old meter and new meter the units used are: OLD Day - 934 Night - 452 NEW Day - 112 Night - 452 The unravelling never ends does it?! If attaching a copy of the bill helps let me know although of course the correct meter readings need to be minused at this stage until they send me an updated, correct one.

Really? Now that I didn't know! I have always thought that the night rate was cheaper and as my night consumption is 4 times my day consumption then that would work out better overall. Scrutinising my bill again it seems the day rate is cheaper indeed but I've grown up with the idea that economy 7 meant electricity used at night was cheaper. As I said earlier I'm pretty on the ball so now wonder how anyone who isn't gets by!

do have E7 and gas for heating and cooking - didnt know it was unusual though. House is 2 bedroom with 3 occupants (2 before october) and I do have a pond filter running all the time but that has been in place since i bought the house in 2004 so not a new use of power.

Thanks for your advice everyone although before I'd caught up on the posts I found a piece of card tucked behind my new meter with the start readings on it which i had no idea was there! This has made everything clear as the start readings were 376 and 1855! I checked with lowri beck and they insisted they had sent these readings to npower and on speaking to npower today with all my facts straight they insisted lowri beck had done no such thing. Anyway the upshot is that they are sorting out my account so I feel slightly sheepish for getting in such a flap on here! BUT I am really pleased it happened in some ways as it brought me to this site that i had no idea existed and i have learnt an awful lot about my power supply and bills that i wouldnt have otherwise. I am pretty clued up with finance and bills but this has taught me there is always more to learn! Thanks again all!

For the 130 days from 9/8 to 17/12 I've been charged £130.76 and then the 48 days from then to 2/2 I've been charged £157.29. I wasnt concerning myself with the amount of money as much as the kWh the new meter is reading compared to the old one when nothing has changed in my house.

Not sure what you mean! Yes I know the bill runs from August to Feb but why has my average useage (which I calculated myself) multiplied by 13.5 times since the new meter was installed? They've broken down the bill for me so I can this clearly.

yes it's a bill from august to last week when the meter reading was taking. The new meter was fitted on 17/12 and so there was a meter reading from the old one before it was removed. For 130 days it measured 452kWh and then for the 49 days from 17/12 on the new meter it measured 2307 kWh!

i only moved to them in may last year but this is my second bill. The change in useage is very clear though as they have put the date when the new meter was installed and started it from 0 on 17/12/10 and the bill goes back to last August. The old meter had a dial which went round and then the numbers which click round whereas the new one is digital - is this the imperial to metric problem that others seem to have had with gas meters on here?

so sorry for putting this in the wrong place - i only have a little bit of time at lunch so couldnt read and search through everything to get it right. doh! Thanks! k

I received my recent bill from Npower for elec and gas this morning to be sickened by the fact i apparently owe them £318 even though i pay by d/d every month! Sadly i'm not at home so can't check their meter readings from last week until tonight but on closer scrutiny I noticed that the elec meter was measuring 13.5 times more kwh each night than the old meter had! Yes power prices have gone up but nothing has changed in my home to justify a new meter measuring that much more electricity being used each night (I have night/day measurements on my meter and did on the old one too). Has anybody else experienced this? I have emailed them to highlight this issue and will await their reply before I take it any further of course. I can foresee no way of them justifying this happening though! Anyway any thoughts let me know. Thanks! Krys
