Hi Frances1970, While you have provided a wealth of infomation there is much that you haven't provided that is unfortunately quite important. I'll put together a list of the infomation that'd be real useful in helping you with this situation. In the meantime, you have two choices either A. While we work through the problem allow the direct debit to be increased or B. request that for your next payment (and maybe a subsequent payment) that you direct debit is reduced back to earlier levels. As you are in credit they cannot refuse this although they can and will vehemently (overly so maybe) attempt to persuade you otherwise.
While I can understand your concerns over the disparity between your own bills and that of your mother there are too many varibales to make an accurate comparrison. Tarriff, usage, building make-up, energy efficiency measures, appliances, metering are just a few examples.
1. I'd like to know if your energy bills have been based on actual meter readings, either provided by the meter reader or by yourself.
2. Can you obtain your annual consumption according to British Gas, and what tarriff are you on.
3. You called for a refund, but didn't clarify if you actually got one. Did you get a refund AND an increase in your direct debit, or just an icnrease in your payments.
4. You mention a gas upply, is this also with British Gas if so is it on the same tarriff as your electricty, if not whcih tarriff and which supplier.
5. Does the meter serial number printed on your bill match the number on your physical meter?
This will help me answer your concerns about British Gas's decision. Additionaly if you could answer the points below we can look at improving the your situation.
A. Do you have regualar access to the internet?
B. Do you own the property?
C. Are there any area's where you will be able to sensibly reduce you consumption (energy efficiency -- turning applainces off, energy efficient lightbulbs etc.)
D. Can you take your meter readings at the begining and end of a 7 day period, during which use your energy as you normaly would and provide those readings here.
