Which offers more tariff options?

While some people like their provider to offer a range of tariffs, there are good suppliers that offer one type of tariff really well, so it’s worth considering a range of providers.

Both of these suppliers offer a broad range of tariff types designed to cater for a range of circumstances. They also both offer time-of-use tariffs designed for electric vehicle owners who wish to charge their cars at home at night, when there is typically less pressure on the grid.

They both sell pre-payment tariffs, which can offer households better control over how much they spend on their energy usage. But it’s worth bearing in mind that pre-payment tariffs are typically a more expensive way to power your home when compared to energy supplied through a “standard” credit meter and paid for via direct debit.

Both suppliers may charge an early exit fee if you want to move to a different supplier. The fees vary depending on your tariff.
