Are energy websites misleading customers?

The big five energy comparison sites have admitted they earn up to £30 in commission every time a customer switches provider.

When customers change both electricity and gas accounts, they charge up to £60.

The figures emerged as the bosses of five price comparison sites were questioned by MPs on the Energy Select Committee.

The price comparison sites argued that the fees were justified, but have been accused of failing to show the cheapest deals for some customers.
