There are six main electricity suppliers in the UK. These are British Gas, E.ON, npower, Scottish Power, Scottish and Southern Energy and EDF Energy.

Global warming and the decrease in traditional fossil fuels such as coal and natural gas means electricity suppliers are sourcing alternative means of supplying electricity to customers. As well as Britain’s six major suppliers offering green electricity plans, there are also green electricity suppliers such as Ecotricity and Good Energy who specialise in green plans.

Green electricity plans do differ in their "greenness" with two main types of plans available. Green supply plans match some or all of the electricity you buy with the equivalent purchase of renewable energy, which the supplier makes on your behalf. The plan will detail how much electricity in your supply is renewable and from where it is sourced.

The second plan is a green fund where you pay a small premium on your tariff to fund renewable electricity schemes. Your electricity supply does not change but you are contributing to future renewable initiatives.
