What do Ovo Energy's gas and electric tariffs offer?

Contrary to popular belief that green energy tariffs are expensive, OVO Energy tariffs aim to offer green energy at affordable prices. Some of their most popular tariffs are:

Better Smart Tariff

The lowest priced green tariff from OVO, this is a fixed tariff of 12 months which allows you to upgrade for free to a smart meter, in case you don’t have one already. You can also participate in the OVO Interest Rewards Program, which lets you earn 3% on your energy credit balance in the first year of your contract, and 4% and 5% in the second year and the following years respectively. There is an exit fee of £30 that applies to this contract, in case you wish to switch early.


Simpler Energy Tariff

For greater flexibility, you can opt for the variable Simpler Energy Tariff, which works on a flexible rolling contract. Energy prices are not fixed under this tariff, so you might end up paying more or less depending on the wholesale price of energy. However, on the upside, you can still participate in the OVO Interest Rewards program; plus, you don’t have to pay exit fees on this contract.
