Get a cheaper deal

Energy suppliers make a lot of money if you don't switch! If you've never done a price comparison or you've come to the end of an energy contract, there's a good chance you'll be on a 'standard variable' tariff. This is normally the most expensive rate your energy supplier offers, so by switching to a fixed rate you can usually save a decent amount.

Take back control

If you don't compare prices, your energy provider will pick a tariff for you! An energy switch takes less than 5 minutes - and it means you can select the best energy plan for you. Looking a cheap energy deal? Want a dual fuel tariff to reduce your energy bills? Perhaps you'd like a green energy supplier? We do a whole of market comparison so you can choose.

Frequently asked questions about energy comparison

The majority of households in the UK are overpaying on their energy bills, so it’s very likely that you are too. This is especially true if you are a customer of one of the Big Six energy companies (British Gas, EDF Energy, E.ON, npower, Scottish Power, or SSE) or are on a standard variable tariff. Comparing energy prices is free, simple, and should only take you a few minutes. By doing so you could save hundreds of pounds on your gas and electricity bills.

No. Your energy supply will continue as normal when you switch energy suppliers. Your gas and electricity will be supplied the same way as before so no changes will need to be made to your home. The only difference you will see is the name of the company on your energy bills, as well as the price you pay.

If you get your gas and electricity from the same supplier, you will be on what is known as a dual fuel tariff. It can often be cheaper to buy your gas and electricity together, although this is not always true. The price of your tariff will always depend on your specific requirements and energy usage. Therefore, it is always essential to compare energy tariffs in order to find the cheapest deals that work for you.

You can switch energy suppliers whenever you wish, although if you are on a fixed price tariff you may have to pay an exit fee depending on how far into your current deal you are. Different suppliers will have different rules, so it’s important to check with your current energy supplier to see how much you could be charged for ending your deal. Suppliers must tell you at least 42 days before your end date that your current deal is about to expire, so this is a good time to switch. If you let your fixed tariff deal end without switching, you will be rolled onto your supplier’s standard variable tariff, which will usually be one of their most expensive deals.

Once you’ve decided to switch and have selected a tariff, you’ll enter a 14-day ‘cooling off’ period. During this time, if you decide you actually don’t want to switch, or that you want to switch to someone else entirely, you are free to cancel to process by talking to your new supplier.

This will depend on several factors, including how much you’re spending now and, most importantly, the kind of tariff you’re currently on. If you’re on a Standard Variable Tariff (which is most likely the case if: you’ve just moved in to a property, your fixed rate deal has finished, or you don’t know what tariff you’re on) then savings can be in the hundreds.

Yes, and you’re likely to get a much better deal if you do. And with the smart meter rollout in the UK well and truly underway, you could also benefit from switching to one of these. A smart meter measures your energy usage in real time and sends this information back to your supplier, which results in far more accurate bills.

However, often people have prepayment meters installed due to arrears from previous energy tariffs, or issues with credit ratings. If this is the case then you may have difficulty switching to a standard meter unless you have cleared your arrears and improved your credit rating.

When the switch goes through, you will be sent a final bill by your current supplier detailing any remaining payments due. For the most part, any debts will simply be included on this bill and won’t hinder the switch (though this will be up to the new supplier). However, if your debts to your current supplier exceed £500, then you’ll need to pay at least a chunk of it back before you’ll be allowed to switch.

In short, no. First of all, you can’t get dual fuel tariffs for your business – you will have to get your business electricity and gas separately. Business energy prices will typically be higher than the energy cost for an average household, even for small businesses. Most energy suppliers offer business energy tariffs, although you might benefit from finding a dedicated business energy supplier, who can tailor you a quote for your specific needs. To get a business energy quote, head over to our business energy comparison page.

This depends on the energy tariff you are currently on. If you have recently switched to a better energy deal, you may already be on the best tariff available to you, so you may not find many opportunities to save when comparing suppliers. However, if you haven’t switched gas and electricity suppliers for over a year, it’s likely you’ll be on a standard variable rate tariff, and comparing energy deals from other suppliers and switching could save you hundreds of pounds on your energy bills every year.

Other than switching to a cheaper energy deal, there are many other ways you can help to keep your bills low. Making sure your home is energy efficient can drastically reduce your overall energy usage, resulting in cheaper bills. Ways you can do this range from the simple (turning off your appliances when not in use), to the complex and expensive (installing loft and cavity wall insulation).

Household energy prices are affected by wholesale energy costs, which in turn are determined by a combination of factors, including supply and demand and international events such as war and extreme weather. The amount of available energy supply is a big driver behind household rates, and when supplies run short, energy prices often increase. Energy prices in recent years have been exceptionally high due to a number of reasons, including the resurgence of demand following the pandemic and the conflict in Ukraine causing supply issues throughout Europe.

The energy price cap is set by the energy regulator Ofgem and is used to cap the amount that energy suppliers can charge consumers, with the cap being reviewed every three months. The cap is not the maximum amount you pay for your energy but refers to the maximum a household can be charged per year for average usage, and your own bills will change depending on how much gas and electricity your household uses. Whether the energy price cap will save you money depends on your energy usage and the tariff you have agreed with your energy supplier, but it will prevent you from being ripped off with rates much higher than the average wholesale costs.

Wholesale energy prices are currently falling, which is expected to lead to lower energy bills for households in the UK. Following this recent reduction in wholesale costs, Ofgem's energy price cap will fall to £2,074 for an average dual fuel household in July, which would make the government's energy price guarantee redundant. However, despite the upcoming drop, household energy bills are likely to remain significantly above pre-pandemic levels for the foreseeable future.

While most people will have heard of the 'Big Six' energy suppliers, you may come across some suppliers who you've never heard of. While comparing prices, you may see that these 'unknown' suppliers are offering better deals, but you may be concerned about the legitimacy of the supplier. Every energy supplier we compare is Ofgem-accredited, so you don't have to worry about any scams or rogue companies. If you're unsure, do some research on the new supplier, such as looking at any online reviews from other customers.

There are several renewable electricity suppliers in the UK, including OVO Energy, Good Energy, Octopus Energy, Ecotricity, Green Energy UK, Outfox the Market, SO Energy, and Shell Energy. However, Green Energy UK is the only domestic supplier of 100% green gas. When comparing energy suppliers with usave, you can see how much of any supplier's energy comes from renewable sources.

No, there is nothing stopping you from getting your electricity from one supplier and your gas from another. But while it's definitely more convenient to have one supplier for both your gas and electricity, it sometimes may work out cheaper to have separate suppliers. That's why it's important to compare energy prices and tariffs between suppliers before committing to any provider.

The Energy Price Guarantee (EPG) is a government-backed energy support scheme that was introduced in October 2022 to limit the soaring costs of energy. The EPG is not the same as the energy price cap set by Ofgem but was used as a temporary measure to further protect consumers in a cost-of-living crisis. It is currently set at £2,500 per year for the average household and will remain so until 30th June 2023. However, since the energy price cap is set to reduce to below £2,500 per year from July 1st, the EPG will effectively become redundant.

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.

Energy comparison sites like usave make money through commission payments from energy suppliers. When you switch energy supplier through our website, we might get a small commission from your new supplier. However, this doesn't affect the price you pay - you will not be charged more for your energy tariff if you switch via usave than if you went directly to the supplier. Many energy suppliers are happy to pay small commission rates to comparison sites like ours as it helps them to save money on advertising and marketing.
