Understanding Energy Suppliers: What You Need to Know

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 now only around 26 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.

At Utility Saving Expert, we understand that everyone’s requirements and priorities differ, which is why we offer a free, impartial comparison service to help you find the best deal.

To begin your search, you’ll need to consider your energy usage, your budget, and any preferences you may have regarding renewable energy or customer service. Once you have a good understanding of your needs, you can start comparing the available options.

Our comparison service allows you to easily compare different energy suppliers’ tariffs, rates, and discounts to find the most suitable plan for you. You can filter the results based on various factors such as price, contract length, and renewable energy options.

We also provide detailed information on each supplier, including their customer service record, green energy options, and any extra perks or benefits they offer, such as cashback or smart meters.

Once you’ve found a plan that meets your requirements, we’ll guide you through the switching process, making it as simple and stress-free as possible. We’ll also ensure that you don’t experience any interruption to your energy supply during the switch.

Remember that switching energy suppliers can often result in significant savings, so it’s worth taking the time to compare and find the best deal for you.
