A survey commissioned by the BBC has found that almost half of domestic energy users don’t know how their bill is calculated.

Although Ofgem has simplified tariff structures in recent years, and limited the number of tariffs suppliers can offer, many still find their energy bills confusing, the survey found.

The survey discovered:

• 51% of consumers have not switched energy supplier in the last 5 years
• 76% of consumers think bills are too complicated
• 44% of consumers don’t understand how their bills are calculated
