uSwitch and price comparison sites are famous for their catchy tv adverts. However, they don’t have to show you the best energy deal up front. They try to cleverly hide the best energy switching deals and show you the ones they get paid for instead. The calculation they use is also flawed. Sometimes, the best option is to wait before switching, but these sites will tell you to switch energy immediately so that they get paid. They are paid big fees when you switch to more expensive deals.
