Good to see that Eon have reduced their tariffs to 5, much less daunting than previously.
Plans 1 and 2 are variable, subject to increases, Plan 2 being 3% cheaper than Plan 1. Three percent discount would give just over £30 discount per year for the average energy user, and for this you would have to sign up for 12 months, subject to a cancellation fee if you see cheaper deals elsewhere. Not a brilliant discount!
The further three plans are fixed rates meaning you will not be charged for any energy increases. However, you have to sign into a contract, subject to cancellation fees if you see cheaper deals elsewhere and want to change supplier.
All tariffs offer rewards, such as Tesco Clubcard vouchers or loyalty rewards, I would prefer that overall prices were reduced, without these gimmicky offers.
Eon's tool did not give tariff prices for individual plans which made it difficult to see how they compared with other energy providers. In order to see full details you would have to research further. What are Eon trying to hide?
Overall - great that Eon are simplifying their tariff structure, but they need to be more transparent with what prices they are actually offering, also cut out their loyalty rewards, and reduce their tariffs.
