Online or paperless tariff
With an online tariff you’ll manage your account online only, with no paper bills or letters. Online tariffs tend to be cheap, as they save the supplier money on postage and paper. They’re also more eco-friendly.
But if you like to file your paper bills away each month, this may not suit you. It’s also worth noting that most online tariffs don’t have customer call centres, so you won’t be able to speak to someone if you have an issue.
Green, ‘eco’ or renewable tariffs can work in a number of ways. One option is that whatever amount of energy you use will be ‘given back’ by your supplier to the National Grid in renewable energy. Alternatively, they may supply your home with 100% renewable energy, a mix of renewable and non-renewable or they may contribute to environmental projects instead.
Green tariffs aren’t necessarily always the most expensive, but price isn’t their selling point and they may cost more than the cheapest tariff.
