Quandry - Think we're being undercharged for gas.

Something is not correct here.

990kWh should cost somewhere in the region of £35.

So although that quote above gives the correct calculations for a metric meter(ie.88 cubic metres = 990kWh) you are being correctly charged for an Imperial meter. -i.e. 88 gas units = 2,801kWh. and £82.33(+VAT?) would be about right for 2,801kWh.(approx 3p/kWh)

Blimey this is confusing!

This is with npower. The "cost split" states "first 990 at 8.315p".

Just checked prices on their website and standard gas is listed as 8.042p per kwh. There are prices listed at 3p per kwh, but this is with a standing charge of £120 per year.

As an aside, I think the wrong meter number is a red herring as I've just dug out a bill from 2006 with the correct meter number on, but it's still treating meter units as metric.

Ah you didn't explain you were with NPower.

You are a 'victim' of 'seasonal weighting'(sculpting) where in winter you are charged for a much higher number of Tier 1(primary) units than in summer. Only NPower have this structure.

So forget my post 21 above, you are being charged for a metric meter.

One consolation is that your consumption is extremely low. To only use 88 gas units - even if they are imperial - in a winter quarter(2,800kWh) indicates that your annual consumption will be well below average - probably about 8,000kWh.

As indicated previously, I believe that you will have a good case to argue that you should only be backbilled for 12 months.

To me it sounds like npower have taken the details from the transco database which showed it was a 4 dial meter but when they configured it on their system they only set it up as a 5 dial, quite an easy mistake to make so if you were to change supplier it is very likely for the new supplier to bill you correctly.
