Why Switching Energy Provider Still Matters in 2026
The UK energy market has been through enormous changes over the past few years, and if you have not reviewed your tariff recently, there is a good chance you are paying more than you need to. Energy prices have stabilised compared to the peaks of 2022 and 2023, but standing charges continue to creep up and many households remain on default tariffs that are far from the cheapest option available.
The good news is that switching energy provider in the UK is now quicker and easier than it has ever been. The process typically takes around five working days for gas and electricity, and your supply will not be interrupted at any point. In this guide, we will walk you through exactly how to switch, what to look for, and how much you could save.
How Much Could You Save by Switching?
According to Ofgem, households on standard variable tariffs could save anywhere from £100 to £300 per year by switching to a cheaper fixed deal. The exact amount depends on your usage, region, and the deals available at the time, but the potential savings make it well worth spending fifteen minutes checking.
Use the Energy Bill Calculator on Freebies to get an estimate of your current costs and see how they compare to what else is on the market.
Step 1: Gather Your Current Energy Details
Before you start comparing deals, you need to know exactly what you are currently on. Dig out a recent energy bill or log into your existing supplier’s app and note down the following:
- Supplier name – who you are currently with
- Tariff name – usually shown on the first page of your bill
- Payment method – direct debit, prepayment, or pay on receipt
- Unit rate – the price per kWh of gas and electricity
- Standing charge – the daily fixed cost
- Estimated annual usage – usually shown in kWh on your bill
- Exit fees – check if your current tariff charges a fee for leaving early
If you cannot find your bill, most suppliers let you download a PDF from their website or app. You can also submit a meter reading before switching to make sure your final bill is accurate.
Step 2: Compare Tariffs on a Comparison Site
Once you have your details to hand, head to an OFGEM-accredited comparison site. Popular options include Uswitch, MoneySuperMarket, and Compare the Market. Enter your current usage and postcode, and the site will show you a list of available tariffs sorted by potential savings.
Look beyond just the headline savings figure. Some tariffs come with introductory discounts that end after a few months, while others offer longer-term price stability. Pay attention to the following factors:
- Fixed vs variable tariffs – A fixed tariff locks in your unit rate for a set period, usually 12 months. This gives you certainty about your costs. A variable tariff can change at any time, which means your bills could go up or down.
- Standing charges – Two tariffs might have the same unit rate but very different standing charges. Over a year, a difference of 5p per day adds up to £18.25.
- Exit fees – Some fixed tariffs charge £30 to £60 per fuel if you leave before the term ends. Factor this in if you think you might want to switch again.
- Green credentials – If renewable energy matters to you, look for tariffs that are 100% renewable electricity. Some of these are now competitively priced.
- Customer service ratings – A cheap tariff is not much use if you cannot get through to anyone when something goes wrong. Check Trustpilot reviews and Citizens Advice supplier ratings.
Step 3: Check for Switching Incentives and Refer-a-Friend Offers
Many energy suppliers offer bonuses for new customers. These can significantly boost your savings and are worth hunting for before you commit. Common incentives include:
- Account credit – Some suppliers offer £30 to £75 in credit applied to your account within a few weeks of switching
- Refer-a-friend schemes – Suppliers like Octopus Energy run generous referral programmes where both you and the person who referred you receive credit. Check out the Octopus Energy deals page on Freebies for current offers
- Smart thermostat bundles – Some suppliers include a free smart thermostat or other energy-saving device with certain tariffs
- Dual fuel discounts – Getting both gas and electricity from the same supplier often comes with a small discount
These incentives can add £50 to £100 in value on top of the savings from a cheaper tariff, so always factor them into your decision.
Step 4: Initiate the Switch
Once you have chosen your new tariff, the switching process itself is straightforward. You can usually initiate the switch directly through the comparison site or by visiting the new supplier’s website. Here is what happens:
- You provide your details – Name, address, current supplier, tariff, and a meter reading. The whole process takes about ten minutes online.
- The new supplier contacts your old supplier – They handle the switchover coordination. You do not need to call your old supplier yourself.
- A cooling-off period applies – You have 14 days to cancel the switch if you change your mind, with no penalty.
- The switch completes – For gas and electricity, the switch typically takes around five working days after the cooling-off period. There is no interruption to your supply at any point.
- Your final bill is calculated – Your old supplier will send a final bill based on your closing meter reading. If you are in credit, you should receive a refund within 14 days.
One important note: if you have a smart meter, it may lose its smart functionality when you switch suppliers. This is more common with first-generation SMETS1 meters. SMETS2 meters generally work across all suppliers. Check with your new supplier before switching if this is a concern for you.
Step 5: Review Your New Tariff Regularly
Switching is not a one-and-done task. Fixed tariffs typically last 12 months, after which you will be moved onto your supplier’s standard variable tariff. This is usually more expensive, so set a reminder for about a month before your fixed term ends to start comparing deals again.
A good habit is to check comparison sites every six months, even if you are still within a fixed term. You might find an even better deal has appeared, or you might confirm that your current tariff is still competitive. Either way, staying aware of the market means you are less likely to end up overpaying.
What About Switching Water Provider?
Unlike gas and electricity, most UK households cannot choose their water supplier. If you live in England or Wales, your water supplier is determined by where you live. However, if your property has a water meter, you can still save money by reducing consumption and checking whether you are eligible for any social tariffs or assistance schemes offered by your water company.
You can use the Water Bill Calculator to check whether switching to a metered supply could save you money. As a general rule, if you have fewer people in your home than bedrooms, a water meter is likely to reduce your bills.
Switching Broadband and Mobile at the Same Time
While you are in the mood for switching, it is worth reviewing your broadband and mobile contracts too. Many people stick with the same provider for years out of inertia, even when much cheaper deals are available. Ofcom now requires providers to send end-of-contract notifications, so check your recent communications from your broadband and mobile providers.
For broadband, switching is now even easier thanks to One Touch Switch, a system that lets you switch provider without having to contact your current supplier. You simply sign up with the new provider and they handle the rest. The Broadband Cost Calculator on Freebies can help you work out whether you are overpaying.
For mobile, consider whether you really need a contract handset or whether a SIM-only deal would be cheaper. Once your handset is paid off, moving to a SIM-only plan can cut your monthly bill dramatically. The Phone Contract vs SIM-Only Calculator breaks down the numbers.
Common Switching Myths Debunked
“Switching means my power will be cut off”
This is completely false. Your gas and electricity supply continues uninterrupted throughout the switch. The only thing that changes is which company sends you the bill.
“It takes weeks of paperwork”
The actual time you spend on switching is about ten to fifteen minutes filling in an online form. The supplier handles everything else behind the scenes. The full switch takes around five working days for gas and electricity, but you do not need to do anything during that time.
“I need to contact my old supplier”
No, your new supplier handles the entire process. The only thing you need to do is provide an up-to-date meter reading when prompted, so your final bill from your old supplier is accurate.
“Switching will damage my credit score”
Energy suppliers do not report to credit reference agencies in the same way that lenders do. Switching energy provider will not affect your credit score. However, if you leave unpaid bills with your old supplier, those could eventually be passed to a debt collection agency, which would affect your credit file.
