Why your energy firm’s cheapest deal might not be its cheapest

Dealing directly with an energy company might seem like a fail-safe way to get the best price from it – but it’s not necessarily the case. The cheapest deal for half of the biggest energy companies was not available directly from their own websites, according to our snapshot investigation.

We checked the websites of 12 of the biggest energy companies in December 2019 and compared the price of the cheapest deal quoted to us with the cheapest deal available elsewhere from the same company, according to available whole-of-market data.

A customer using a large amount of energy in the east of England, for example, could have ended up paying nearly £300 more per year by picking a tariff from one supplier’s website than they would have paid had they looked on a third-party comparison site.

Read on to find which suppliers didn’t list their cheapest deals on their website in our investigation and how to get the best deal from your energy company.
