Hi all,
There are a few issues here so I'll put up some info on each and if I miss one, let me know.
Basics about your gas meter and types, large bills..
Here is an extract from another of my posts on a similar subject which might be useful
"In reference to the bill you have, I would suggest a few simple checks that you can perform yourself.
Firstly.. Check the meter serial number on your bill is the same as that on your actual meter. Also look on the meter for a sticker or label indicating the meter has at some point been changed.
The reasons for this are mainly down to 2 things...
1 there are 2 main types of gas meter. a "4 dial" and "5 dial". As the name suggest a 4 dial meter will have four numbers in white which are your reading (also 2 in red but these are not relevant). This meter measures gas per hundred cubic feet. A 5 dial meter has 5 numbers in white (and 3 in red, again not important) and measures in cubic meters. Therefore, each unit recorded on your meter will be worth a different amount dependent on the type you have (or the type they think you have) 1 unit recorded on a 4 dial meter will cost you much more as that represents 100 cubic feet of gas, rather than the 1 cubic meter a 5 dial would record. If you have a 5 dial meter and the company takes these readings and calculates your bills based on a 4 dial calculation, your bill will be huge.
2 Meters, like all things need replaced from time to time and have a lifespan before they need to be replaced or "re certified". This is not a task carried out by your supplier but rather the shipper of gas to your property. (95% of the time this will be transco) They carry out the change and inform the supplier after it has been carried out, but occasionally these details do not get thru and the suppliers records are not updated. (this is more common than you might think) going back to my first point, 4 dials are older meters (identified with a 6 number serial number) and are most often replaced with a newer 5 dial meter (these have a longer serial no of about 13 numbers, usually starting G4....) If these details are not picked up, you get the above scenario.
Secondly,
How much have your payments been and have they sent a bill in that time? have they read the meter themselves? I ask these as for such a large amount, your meter may have "over-cycled"
This means... when your meter records usage (starting at zero for easy counting, and using a 4 dial) it goes
0001, 0002, 0003 and so on till it gets to 9999.. at this point it goes back around to 0000 and keeps counting. Depending on your readings, they may think, or their records might indicate, you meter has over-cycled. (for info once round a 4 dial dial meter is easily 8k and over on new prices) If they have overestimated your bills previously, their system may be so far ahead it thinks you have gone past the 0000 point, when in reality, you haven't."
hope that helps a bit
If you have received a large "catch up" bill
If you have received a large catch up bill due to faults on behalf of your supplier in either not billing you or using very low estimates, under Ofgem regulations, they are only allowed to bill you back for 12 months of the shortfall of payments v usage. An extract from one of their reports reads...
"Suppliers have commercial incentives to provide their customers with accurate bills as part of providing good customer service. To reinforce these incentives, we have worked with suppliers over the last 18 months to establish an independent Ombudsman to deal with billing disputes and end back-billing beyond a year from July 2007." And the full report this is from can be found at the link below, the extract is from page 10.
