Finding the cheapest energy supplier in the UK can be difficult as prices are constantly changing. However, some energy suppliers are known for consistently offering good value tariffs. But with wholesale energy prices so high at the moment, and suppliers restricted by the energy price cap, there is currently little difference between suppliers and tariffs in terms of overall cost, and it will likely remain like this until the market returns to normal. The easiest way to find out who the cheapest energy supplier is at any given moment is to run an energy comparison.
