• Energy Suppliers

Energy suppliers are the companies that supply the gas and electricity in your home. Most energy companies in the UK do not own any of the networks of cables or pipes that deliver the gas and electricity to your home.

We’ve made it easy to start an energy comparison and switch suppliers using Utility Saving Expert.

In the UK there are around 60 energy suppliers. We check the tariffs of every single energy supplier and show you the best tariffs you can get in your home. If you decide to switch to a cheaper supplier, it’s quick and simple with Utility Saving Expert.

We are paid a fee from the suppliers for every switch completed. The fee is already included within the marketing budgets of the energy suppliers so the prices you see on our site are the same as you’ll see on theirs.
