See pricesWhat it means to change your energy supplier.
Switching energy suppliers means choosing a different company to provide your electricity, gas or both.
Think of it as a bit like changing your phone or internet contract – you're looking for a better deal, better service, or maybe even an environmentally-conscious option. And since energy prices fluctuate, regularly reviewing your current energy tariff can help you get the best deal.
What are the common reasons for changing energy suppliers?
People may switch energy providers for many different reasons, such as:
Cost savings.
Switching could unlock significant savings on your energy costs.
Greener options.
Make a positive impact on the planet by choosing a supplier that offers renewable energy tariffs.
Customer service that cares.
Tired of long wait times and unhelpful customer support? Get an energy supplier that has great customer service.
Tariff flexibility.
Find a tariff that perfectly matches your normal energy use and lifestyle. This could be a fixed tariff for a year or a tariff designed for electric vehicle chargers.
What are the key considerations before changing energy suppliers?
Before switching, check for exit fees and your contract terms such as your contract end date.
Check your current energy use, and have your recent energy bills, current tariff information, accurate meter readings and your current supplier’s details to hand.
How much could you save by switching energy supplier?
This is the burning question for most of us. While we can't promise a specific number because it varies person to person, a change of energy supplier could unlock savings on your annual energy costs.
Your old tariff may have been great at the time, but the unit rates and standing charges might not be competitive now. Since energy prices are constantly going up and down due to the price cap, reviewing your energy deal every 3-6 months could help ensure you're not paying over the odds.
To truly understand your potential savings, you'll need to look beyond the headline price and compare the finer details, including:
Unit rate.
The cost for each kilowatt hour (kWh) of energy you use.
Standing charge.
The fixed daily charge that covers the cost of keeping your home connected to the energy network, even if you don't use any energy.
Tariff type.
Whether it's a fixed rate (where your unit price stays the same for a set period) or a variable rate (which can go up or down.)
Exit fees.
Does your current contract have a fee for leaving early? If so, you'll need to add up whether the savings outweigh that cost.
Choosing the best energy supplier to switch to.
Before you make the switch, there’s a few things you should look into first.
Tariff types: Understand the different tariff options available (fixed, variable, dual-fuel, green energy), their pros and cons, and if there’s any exit fees. Try and forecast your annual cost too.
Customer service: Look for suppliers with excellent customer service ratings, and Trustpilot scores.
Renewable energy options: Looking to cut your carbon footprint? Then look for a supplier offering renewable electricity tariffs.
Price caps: Be aware of the energy price cap and how it could affect the tariff you want to switch to.
How to change your energy supplier.
What are the steps when comparing your current supplier with new energy suppliers?
1Gather information.
Look into your current supplier’s tariffs and compare them with new deals with their competitors.
2Compare.
Use price comparison websites and explore the available deals to you.
3Research.
Check government resources like the Energy Saving Trust for unbiased advice and information.
How to estimate your energy use for a new deal.
You've probably noticed that every good energy quote tool asks for your annual energy use. This is because it’s the only way to get an accurate quote. The simplest and most reliable way to figure out your estimated use is to look at your most recent annual energy statement or bill.
If you can't find your bills, you can always use national averages, however, this will only give you a rough estimate. Using your actual kilowatt-hour (kWh) data is the only way to ensure the quoted price is close to the price you'll actually pay.
How to get the most accurate energy quote.
Getting a quote that reflects your actual energy use is key to making the right choice. Follow our simple checklist to help make the process more straightforward.
1Have your data ready.
Have your annual kilowatt-hour (kWh) use for electricity and/or gas (if you're switching both).
2Provide an accurate meter reading.
When you’re asked for your most recent meter readings, provide them as soon as you can. Current readings are essential for the final bill from your old supplier and the opening read for your new one.
3Know your current tariff details.
When comparing, check the unit rates, standing charges, and end date of your existing contract.
4Forecast your annual cost.
Use a reliable comparison tool that lets you plug in your annual kWh use to create a forecast of your total annual cost. This overall figure, rather than just the unit rate, is the best way to judge which deal is cheapest for your home.
The switching process explained.
When you switch suppliers, the process is usually broken down into four steps.
1Choosing a supplier.
Choose your new supplier and sign up for a new deal.
2The switch.
Your new provider contacts your current supplier to arrange the switch.

Frequently asked questions
Can I change energy suppliers now?
You can usually switch energy suppliers at any time, but there might be some restrictions if you're on a fixed-term contract with exit fees. Smart meters generally don't cause any issues when switching.
Why has my electricity supplier changed?
Sometimes your electricity supplier might change automatically due to company closures, government intervention, or supplier buyouts. If this happens, don't panic! Ofgem appoints a new supplier in such cases, and your new supplier will contact you.
Is it worth changing energy suppliers?
Switching energy suppliers could actually save you money, get you better service, and offer more environmentally friendly options. But it's important to compare deals and see what works best for you before making the switch. Sometimes, sticking with your current supplier might be the best choice, especially if they offer a good loyalty rate.
What is the role of smart meters when changing energy suppliers?
If you’ve already got a smart meter, this can make the switching process even smoother and help you track your energy use more effectively. If you have an older smart meter (SMETS1), it's worth checking with your new supplier to ensure it’s compatible with your new tariff.
Understanding your final bill after changing energy suppliers.
Your final bill from your old supplier will include charges for all energy you’ve used up to the switching date, including any outstanding debt, and any credit you're owed. Check this bill very carefully for any errors or discrepancies as you may be eligible for a refund if you’ve been overpaying.
How is my final bill calculated when I change suppliers?
Your final bill will include charges for all energy used up to the switching date, any outstanding debt, and any credit you're owed. It's crucial to check this bill for accuracy and contact your old supplier if you have any questions.
What happens to my credit balance when I change?
Your old supplier is legally obligated to refund any outstanding credit on your account. This usually happens automatically within a few weeks of your switch.
Can I dispute errors on my final bill?
Yes, you have the right to dispute any inaccuracies on your final bill. Contact your old supplier and provide evidence of the error. If the issue isn't resolved, you can escalate the complaint to the Energy Ombudsman.
How does changing energy suppliers work if I have a prepayment meter?
You can still switch suppliers with a prepayment meter. Your new supplier will provide instructions on how to transfer any existing credit to your new account. In some cases, you may need a new meter installed.
Can I switch to a renewable energy tariff?
Many suppliers offer renewable energy tariffs, where the electricity you use comes from sources like wind, solar, or hydro power. When comparing tariffs, check the fuel mix to see how much of the energy is renewable.
What should I do about my energy supply if I'm moving home?
You can usually arrange for your energy supply to be transferred to your new address, or you can choose a new supplier. It's best to inform your current supplier of your moving date and provide them with forwarding details.
Can I switch suppliers if I'm in debt to my current provider?
If you're in debt to your current supplier, you may need to pay off the debt before you can switch. However, some suppliers may allow you to switch with a small amount of debt, which will be added to your final bill.
What if my new supplier goes bust after I've switched?
Ofgem, the energy regulator, has a 'safety net' process to ensure your energy supply isn't interrupted if your supplier goes bust. You'll be automatically transferred to a new supplier, and any credit balance you have will be protected.
How do I know if I'm getting the best energy deal?
Compare suppliers based on tariff type, unit rates, standing charges, contract length, and customer service. Price comparison tools and supplier websites can help you here.
What happens if my new supplier cancels my change?
If a switch is rejected, it may be due to debt with your current supplier or incorrect details. Contact both suppliers to resolve the issue and try again.
Who is responsible for switching my Direct Debit?
When changing energy suppliers in the UK, your new energy supplier is responsible for your Direct Debit. To be clear, there isn’t a ‘switching over’ process, your new supplier sets up a new Direct Debit.
Your new supplier also lets your old supplier know that you're switching and stops your previous Direct Debit after your final bill.
Find more information about switching and Direct Debits at Citizen’s Advice.
Will I need to tell my old energy supplier I'm switching?
Don’t worry, when changing energy providers, you won’t need to tell your old energy supplier that you’re leaving. Your new supplier will sort everything for you.
How early can I switch energy suppliers?
Switching is quick and flexible, typically taking 3-5 days to complete. You’re protected by a 14 day cooling off period if you change your mind, without paying any fees should you change your mind.
Finally, if you’d prefer to switch on a specific date, you usually can. Simply contact your new supplier and let them know the date. This is ideal if you’re nearing the end of a fixed tariff and don’t want to switch until it’s ended.
Where can I get advice on choosing an energy deal?
There are a number of places to get independent and impartial advice on finding the best deal for your home. The most common next step is using a comparison website that has signed up to Ofgem's Confidence Code. This code ensures the comparisons are truly independent and unbiased.
Can I get the best energy deals with no credit check?
Generally, the most competitive fixed rate deals are offered to customers who pay by Direct Debit. Suppliers usually run a credit check for these deals to be confident you'll be able to pay your bill each month.
However, if you're keen to avoid a credit check, you'll likely be offered a Prepayment tariff. This means paying for your energy upfront by topping up a meter. It's important to note that Prepayment tariffs are usually more expensive than Direct Debit options, though the gap has narrowed thanks to the energy price cap.
Can I get the best energy deals with no exit fees?
Yes. Most Standard Variable Tariffs (SVTs), like our Next Flex tariff, don't have any exit fees because they aren't tied to a fixed contract length. So, you're free to switch whenever you want! Just note that the unit price you pay can go up or down with the market.
