How to compare Fixed Price Energy Tariffs?

With many fixed tariffs coming to an end, you may want to compare prices for a new fixed tariff. But it’s not quite as easy as going to an energy price comparison site.

Energy comparison sites add how much you will pay till the end of the fixed term, plus the rest of the year at the standard variable tariff. Then they compare this total with a full year on a new fixed tariff. So it’s not a like for like comparison.

Fixed tariffs are made up of several parts:

  1. The daily standing charge
  2. The unit rate
  3. Less any discounts

So how to carry out a comparison between your expiring fixed tariff and a new fixed tariff?

  1. Get a hold of the above information for the old and new tariffs.
  2. Head over to and select Fixed Tariff Comparisons
  3. Enter the prices for old and new tariffs
  4. This will produce a side by side comparison with the new annual and monthly costs.

If you wish to switch, please consider using The prices available are the same as any other price comparison service.
