There are also three buttons at the top of the table, ‘gas and electricity price’, ‘gas prices only’ and ‘electricity prices only’. Clicking these will re-order the table to show you the best options for each scenario.

The table also contains links to customer reviews for all the tariffs available, allowing you to gain further insight into the deals that interests you.
