British Gas says it will tell its customers every six months whether they are on the company's cheapest energy tariff - but customers need to check elsewhere to make sure they are on the cheapest energy deal around.  

Energy giant British Gas has vowed to send each of its 10 million customers a personalised 'tariff check' on their bill every six months. This will tell them whether or not they are on the company’s cheapest deal. 

British Gas is the first of the major energy companies to provide this service to all customers automatically. However, its tariffs are not the cheapest on the market, and some bill payers could be hundreds of pounds better off by switching to a deal with a cheaper provider. 

If you want to find out which energy company offers the cheapest energy tariff for your home, you can compare gas and electricity prices using Which? Switch, our independent price comparison service.  

Switch to a cheaper energy deal 

Households that are on British Gas's most expensive tariff, Sustainable Energy (with standard gas) tariff, could save £316 a year on average by switching to the cheapest deal on the market, Spark Energy's Advance tariff. 

And even customers on British Gas's cheapest dual fuel tariff, Online Variable February 2014, could save £152 on average by switching to this Spark Energy tariff.

British Gas customer service

British Gas came 11th in the most recent Which? energy supplier satisfaction survey. This puts it ahead of some of its big six rivals, such as Npower and EDF Energy, but a long way behind smaller energy companies, such as Good Energy and Ecotricity.

Simple energy tariffs

Which? believes that radical action is required to increase competition in the energy market. 

We want simpler energy tariffs that make it easier for consumers to choose the best deal. And we want the government to introduce a single unit price for energy, that would apply to all tariffs and allow people to spot the cheapest deal at a glance.
