Current standard tariffs from the Big Six

The Competition and Markets Authority recently found that about 70% of households are on a ‘default’ standard variable tariff. These are generally a lot more expensive than cheaper fixed deals. If you're on one of these tariffs, you are paying too much. 

Our research found that if you're on a standard tariff with one of the Big Six, you could save up to £299 by switching to the cheapest deal:

1. Eon £1,135: £265 more expensive than GB Energy Supply Premium Energy Saver

2. SSE £1,146: £276 more expensive

3. EDF Energy £1,155: £285 more expensive

4. British Gas £1,156: £286 more expensive
