Hoping someone can point me in the right direction.
We have been with Scottish Power for apx 6 years. We had a series of meter readings back in 2003-2005 and then another in Jan 2007. This was our last actual reading and since then, our bills have been based upon estimates.
S.Power recently contacted us to request a reading (after 2.5 years) and it would seem that there was an underestimate over recent years, resulting in a bill for £3500.
Following a series of calls from us to S.Power, they then contacted us to advise that there was an 'error' at their end and they would be writing off a period of 6 weeks and then recalculating our bill for the last 12 months (up to the most recent meter reading). They have not been clear about what the error was (I suspect it was simply not reading the meter and using poor estimates).
They have advised today that they are sending a 'revised' bill which is slightly lower than the £3500 and I should receive this in the next couple of days. I asked them 2 questions (which I hope the forum can assist with)
1. Since they have no actual readings, what reading will be used to 'start' the period? ie. How do they know what was used in the past 12 months and what was used in the previous 1.5 years?
2. Secondly, assuming we agreed on the usage figure, what tariff is applied to the reading? Our pence/KWH has risen dramatically in the past 12 months....so what price is used to calculate the bill given that they have no idea when the electricity was used?
They have been pleasant on the phone, but ultimately couldn't answer Q2 above. They did say that the usage would be calculated on some 'average usage basis'.
Should I be doing anything? Does it matter that they didn't read the meter for 2.5 years? Do I have grounds for disputing the bill?
Any advice much appreciated
