How to Use an Energy Comparison Site (Step-by-Step Guide)

Why Use an Energy Comparison Site in 2025?

With energy costs going up and changes in the energy price cap, it can be a good idea to use an energy comparison site. These sites help people in the UK see and compare energy prices. You do not need to contact each supplier on your own. This makes it easy to find new deals, check the latest price cap, and get potential savings on your energy bills. It is a good way to keep up with any updates and look for better deals for your energy.

It does not matter if you use a prepayment meter, a smart meter, or if you have just moved into a new home. These platforms are here to help you save.

What Is the Best Way to Compare Energy Prices Online?

The best way to compare energy prices is to use an Ofgem-accredited comparison site. You’ll need your postcode, current supplier, energy usage, and meter type. After submitting these, you’ll see available tariffs, including fixed and variable options. Choose the one that best fits your usage and budget.

Step 1: Gather Your Details

Before you go to a comparison site, be sure to have all of these things with you:

• You will need to give your postcode.
• Tell them who your energy supplier is and what your tariff is called.
• Share your energy usage for the year in kWh. You can get this from your last meter reading or bill.
• Let them know your payment method. This could be Direct Debit or paying when you get a bill.
• Say if you use dual fuel or just need electricity.
• Tell them which kind of meter you have. Is it a standard, smart meter, or a prepayment meter?

If you do not know how much energy or how much electricity you use, most tools will give you an average. They will often look at your household size for this. It is good to know your unit of energy and your usage. This can help you get the best and most accurate deal for you.

Step 2: Choose a Trusted Comparison Site

Make sure that the tool you use is Ofgem-accredited. That means the comparison you get will meet the right standards. It will be easy for people to see, and the facts will be correct and clear.

Popular energy comparison tools include:

• Free Price Compare
• Uswitch
• MoneySuperMarket
• Compare the Market

Step 3: Enter Your Information

Start by adding your postcode. After that, finish the rest of the form.

• Pick the energy supplier you use now.
• Type in how much energy you use, or just use the average amount.
• Choose the payment method that fits you.
• Say if your meter is smart, standard, or a prepayment one.

Many tools will give you the option to filter by:

• A fixed tariff means the price is the same every month. A variable tariff can go up or down with time.
• There are deals from a new energy supplier, or you can pick a new supplier if you want to change.
• Some tariffs help people with electric vehicles or let you use more renewable energy from renewable sources.

If you want to get the most out of your tariff, you should look at each plan that your energy supplier offers. A new deal may help you use more renewable energy from better renewable sources.

Step 4: Review Your Results

After you send it in, you will get a list of the energy tariffs that are offered.

You can also sort by:

• Price (start with the lowest and go up to the highest)
• Supplier rating
• Perks (like cashback, getting paperless discounts)

Step 5: Select a Deal and Switch

Once you choose a deal:

1. Click on the link if you want to say yes and go ahead with your switch.
2. If they need more personal info, give it to them. This can be your email address or bank details.
3. Wait for a message. The new provider will let you know that they will take care of the energy switch for you.

You do not have to worry about losing your power during the switch. The Energy Switch Guarantee will make sure that everything goes well. It will take about 5 to 10 working days to make the change. Some companies also give you a warm home discount or a winter fuel payment.

Step 6: Submit Regular Meter Readings

After you change, keep sending in regular meter readings if you do not have a smart meter. This will help you get the right amount on your bill.

Benefits of Using an Energy Comparison Site

• Save money on your energy bills by choosing better electricity deals.
• You can see prices from many energy companies in one place, so you can make the best choice.
• Pick a fixed rate tariff to keep the same rate, or go with a variable tariff if you want more flexibility.
• Check payment plans and choose green renewable energy options that fit you.
• Do not pay too much to your old supplier. Move to a fixed rate tariff and you may get good news about lower prices in June and September.
