Frequently asked questions

What kinds of tariff are available?+

The range covers fixed, variable, tracker, EV, time-of-use, dynamic and green tariffs, plus a small number of prepay options. That spread lets you pick a rate that matches how you use power, from a stable fixed deal to one that follows the market.

Is switching to a SmartEnergy Holdings plan free?+

Most plans carry no switching charge, with a smaller number using a share-of-savings or subscription model instead. If a plan is paid for on a savings share, the amount you keep depends on the tariff terms, so weigh that against a plan with a straightforward monthly cost.
