Comparison Site Inaccuracy - Beware

ritchiewags

Hello All,
:exclamatiBeware moneysupermarket.com
I recently used moneysupermarket to search for a cheaper dual fuel tarrif. I entered both current monthly spend and anual usage. They came up with slightly different savings (how is that possible:cool:). Anyway, I decided to switch to eon (coming second in each search and good customer service rating:)) with a saving of either £143.23 or £74.73 (first is spend, second usage:cool:). The documents arrived from eon today and I used their figures to calculate the saving - an amazing £16.18 anually:eek:. This was their fixonline v8, which seems a good deal. I cancelled the switch as I didn't want to commit to fixed prices for a year and a £30 cancellation fee - all for a saving of £1.52 a month. Even if you add in the £30 cashback its still a poorer deal than they reckon.
This not a criticism of eon , but of moneysupermarket, who must be pulling figures out of thin air for their calculations:cool:

Did you work out the savings using the unit rates from E-on?

If so did you include the discounts in your calculations (which can be up to 27% with E-on)

If you put your usage into a comparison site its highly unlikely it would have been inaccurate.

Post your figures here and we'll have a look.

This is not unique to the comparison site you refer to, but to all comparison sites.

You only get accurate figures if you input your consumption in kWh.
If you input expenditure, the comnparison sites make some estimations as to your actual consumption and this is where the variations come from. Monthly spend by DD can be significantly different to actual consumption as many threads from those who post who are are hugely in credit or debit testify to.

(You get accurate figures whether you use spend or kWh. It is, however, a lot easier to keep track and know what's going on when you use kWh.)

Just did an iteration on moneysupermarket - absolutely no difference between their suggested saving and the tariff from E-on's own site.

Please provide more evidence, OP.
