Top Questions About Switching Energy Suppliers in the UK
Switching your energy supplier is quick and hassle-free. All you need to do is enter your postcode. We’ll retrieve your current usage, supplier details, and tariff — just confirm the information is correct. Then, you’ll see a list of available tariffs you can switch to online.
Once you’ve selected a deal, the switch takes less than 4 minutes to complete. After that, all you’ll need to do is submit a final meter reading to your old supplier. We’ll handle the rest — no paperwork or phone calls required.
Energy suppliers often reserve their best deals for new customers. If you don’t actively switch, you’re likely to be moved onto a standard variable tariff — typically the most expensive type of plan. These tariffs are subject to price increases and include higher unit rates and standing charges.
Switching regularly ensures you stay on competitive energy rates rather than overpaying on a default tariff. By comparing prices and choosing a better deal, you could significantly lower your gas and electricity bills.
No — you won’t lose your gas or electricity supply when switching energy providers. The change is seamless, and your energy flow remains uninterrupted throughout the process.
The only difference you’ll notice is the new tariff and price on your bill. Your energy will still be delivered through the same network and infrastructure, regardless of which supplier you choose.
Yes — you can still switch energy suppliers even if you don’t know your exact usage.
If you have a smart meter, we’ll use your latest 24-hour usage data. If not, we estimate your energy consumption based on your most recent meter reading or average usage for your home type.
We’ll present your projected usage in kilowatt hours (kWh) and monthly costs, so you can confidently compare tariffs and choose the right deal.
No — the gas and electricity you receive will be exactly the same, no matter which supplier you choose.
All energy in the UK is delivered through the National Grid, so switching supplier only changes the company that bills you — not the source or quality of your supply.
The only thing that changes is the name on your bill and the tariff you’re paying.
While we don’t currently offer phone support, our online comparison tool is designed to guide you through every step of the switching process.
You’ll find all the information you need on our website, including FAQs, energy guides, and tariff breakdowns. Our platform is built to be clear, fast, and user-friendly — so you can switch energy suppliers with confidence and ease.
The amount you could save depends on your current tariff, usage, and location. Due to the volatility in the energy market since late 2021, it's difficult to give a general savings figure.
However, when you use our comparison tool, we’ll show you the best available tariffs based on your current usage. Any potential savings will be clearly displayed on the results page — so you can make an informed decision before switching.
Switching energy suppliers in the UK typically takes 15 to 20 calendar days from the moment you start.
Here’s how it works:
- You get a 14-day cooling-off period, during which you can cancel the switch if you change your mind.
- The actual switch happens within 5 working days after that period ends.
- In some cases, your new supplier may start preparing the switch during the cooling-off period — but it won’t be completed until it’s over.
This faster switching process ensures a smooth and reliable transition to your new energy provider.
Yes — you have a 14-day cooling-off period after agreeing to switch energy supplier.
If you change your mind during this time, you can cancel the switch without any penalties or fees. The process is completely risk-free while you're within the cancellation window.
It depends on your current tariff.
- If you’re on a standard variable tariff, you can switch energy suppliers at any time with no exit fees.
- If you’re on a fixed-term contract, your supplier may charge an early exit fee — usually between £15 and £30 per fuel.
However, you can switch fee-free in the final 49 days of your contract — this is known as your renewal window. Also, if you're moving house, most suppliers will not charge a penalty for ending your contract early.
You should review your energy tariff at least once a year, or 49 days before your current contract ends.
This is known as your renewal window, and it allows you to switch suppliers without paying any exit fees. While most energy contracts are 12 months, some can last 24 or even 36 months — so always check your end date and compare prices in advance.
Regular switching helps ensure you're not rolled onto a higher-rate standard variable tariff when your deal ends.
Yes — in most cases, you’ll pay the same price through Free Price Compare as you would by going directly to the energy supplier.
In fact, we sometimes offer exclusive tariffs not available on supplier websites, thanks to the high number of customers who switch through our platform.
Plus, you can compare multiple suppliers in one place — saving time and effort compared to visiting each website individually.
Why Are Energy Prices Still High in the UK?
Energy prices remain a key concern for many UK households. While costs have started to come down since the 2021–2023 price surge, they are still higher than pre-crisis levels. Here's why energy bills are still elevated — and what you can do about it:
Wholesale Gas Prices Remain High
Although wholesale prices have dropped from their peak, they are still significantly above historic averages. Ongoing global supply chain issues and geopolitical tensions continue to affect the cost of gas — a major driver of UK energy bills.
The Ofgem Energy Price Cap
The Energy Price Cap, set by Ofgem, limits what suppliers can charge on standard variable tariffs. While it's reviewed every three months and has fallen slightly, it still reflects elevated wholesale costs — so household bills remain higher than expected.
Fossil Fuel Dependence
A large portion of UK electricity and heating still comes from gas. The transition to renewables is underway, but until it’s fully realised, fossil fuel dependency keeps prices volatile.
Rising Supplier Costs
UK energy suppliers face increased operating and regulatory costs. These are passed on to consumers, which limits how much prices can fall — even when wholesale rates ease.
What You Can Do
Even though prices remain high, you can take control of your bills:
- Compare energy deals to find cheaper fixed or variable tariffs
- Switch suppliers within your renewal window to avoid default rates
- Use smart meters and home energy tips to reduce consumption
What Is the Energy Price Cap?
The Energy Price Cap is a limit set by Ofgem on what energy suppliers can charge for each unit of gas and electricity. It was introduced to protect UK consumers from unfair price increases — particularly those on standard variable or default tariffs.
How Often Is the Price Cap Reviewed?
Ofgem reviews the price cap every three months. Adjustments are based on changes in wholesale energy costs, network charges, and other industry factors. This helps ensure energy prices reflect current market conditions while still offering a degree of protection to households.
Current Price Cap (As of October 2025)
From 1 October to 31 December 2025 the price for energy for a typical household who use electricity and gas and pay by Direct Debit will go down by 7% to £1,755 per year. For a typical household, this will reduce their energy bills by £11 a month.
What the Price Cap Does (and Doesn’t) Cover
The cap sets a maximum unit rate and standing charge — not a total bill limit. If you use more energy than the average household, your total costs may still exceed the capped amount.
Can You Save More by Switching?
Yes — while the price cap offers some stability, it doesn't always represent the cheapest option. Many suppliers offer fixed-rate tariffs or exclusive online deals that can beat the capped prices. Comparing energy deals regularly is one of the best ways to reduce your bills.
When Will Energy Prices Go Down in the UK?
The UK energy market remains unpredictable, and the Ofgem Energy Price Cap has seen several changes over recent months:
- July to September 2024: £1,755 per year (typical dual-fuel household, direct debit)
- October to December 2024: £1,834 per year
- January to March 2025: £1,738 per year
These figures are based on Typical Domestic Consumption Values (TDCVs) and assume average household energy usage. While prices have fluctuated slightly, they remain higher than pre-crisis levels.
Why Prices Are Still Volatile
Several factors are keeping energy prices elevated:
- Wholesale gas prices remain unstable due to global supply issues.
- Network and operating costs continue to rise for UK energy suppliers.
- Environmental and VAT obligations also influence final consumer prices.
Even when wholesale prices fall, other cost factors may delay reductions for households.
What to Expect Going Forward
Experts suggest that energy prices may stay elevated for the foreseeable future due to:
- Ongoing global market uncertainty
- Slower-than-expected transitions to renewable energy
- The impact of geopolitical tensions on supply chains
How Consumers Can Take Control
While the market is out of your hands, your bill isn’t. You can:
- Compare energy prices regularly to ensure you’re not overpaying
- Switch suppliers when better tariffs are available
- Improve energy efficiency at home with smart meters, insulation, and lower usage habits
Final Tip: Use our free energy comparison tool to check if you could save money right now by switching to a cheaper deal — even in today’s market.
How to Compare Energy Prices Effectively in 2025
Comparing gas and electricity prices is one of the best ways to lower your energy bills. Follow these simple steps to find the best energy deals for your home:
1. Use a Trusted Energy Comparison Site
Start by visiting a reliable platform like Free Price Compare. Just enter your postcode, current supplier, and estimated usage. You’ll instantly see a tailored list of available gas, electricity, and dual fuel tariffs in your area.
2. Choose Between Fixed and Variable Tariffs
- Fixed tariffs lock in your unit rate for a set period, usually 12 to 24 months. They offer price stability and protection against market spikes.
- Variable tariffs follow wholesale prices — they can go up or down, offering flexibility but less predictability.
Choose based on how much certainty or flexibility you want.
Want to dive deeper? Check out our Fixed Price Energy: Is It the Right Choice for You? to understand more.
3. Check Contract Terms and Exit Fees
Don’t just focus on the monthly cost. Look at:
- Contract length
- Early exit fees
- Renewal options -
Also consider extras like green energy tariffs, rewards, or bundled services that might benefit your household.
4. Read Customer Reviews
Check reviews and ratings to understand how reliable and helpful a supplier is. Consider customer service quality, billing accuracy, and responsiveness when evaluating deals.
5. Make the Switch with Confidence
Once you’ve chosen your tariff, switching is simple. Free Price Compare handles the process from start to finish — including contacting your new and old suppliers. You won’t lose supply, and you’ll receive all notifications directly.
Energy Expert Commentary: Understanding the Price Cap and Market Trends
Our Energy Experts Says:
The Ofgem Energy Price Cap is reviewed and updated every three months to reflect wholesale costs and other market factors. While prices have come down from the peak levels seen in 2022 and early 2023, they remain higher than pre-crisis norms.
The Energy Price Guarantee, a government support measure, ended in 2024. Since then, households have returned to market-based pricing under Ofgem’s regulated cap. While this offers a level of protection, it doesn't always guarantee the lowest available rates.
That’s why it’s important to compare energy deals regularly. Many suppliers now offer fixed-rate tariffs and other competitive options that may beat the price cap, especially if your energy use is consistent.
Use Free Price Compare to explore the latest unit rates, standing charges, and exit fees — so you can make an informed decision about switching to a better deal.

Energy ExpertUnderstanding UK Energy Tariffs: Dual Fuel, Single Fuel, Fixed, and Variable
Dual Fuel vs Single Fuel Tariffs
A dual fuel tariff means you get both your gas and electricity from the same energy supplier, under one contract. You’ll receive one bill for both fuels, and some suppliers may offer discounts or loyalty incentives for dual fuel customers.
What is a Single Fuel Tariff?
A single fuel tariff means you choose separate contracts for
your gas and
electricity — either with the same supplier or different ones. This can provide more flexibility
and potentially
lower prices if the best gas and electricity deals come from different providers.
Which is Better?
- Dual fuel is often more convenient with one bill and fewer admin tasks.
- Single fuel may be more cost-effective if you shop around and choose the lowest rates for each fuel separately.
You can compare both options using filters on the Free Price Compare platform to see which offers the best deal for your usage.
Fixed vs Variable Rate Tariffs
Fixed Rate Tariffs
A fixed rate tariff locks in your energy unit rates and standing charges
for the length of
your contract — typically 12 to 24 months. This provides price certainty and protects you from
wholesale market
increases.
Key Points:
- You’ll still pay more if you use more energy — your bill isn’t fixed, just your rates.
- Fixed tariffs often include exit fees (up to £125 per fuel), though you can switch fee-free within 49 days of your contract ending (your “renewal window”).
- Some new suppliers may even cover your exit fees to win your business.
Ideal for: Households wanting price stability and control over budgeting.
Variable Rate Tariffs
A variable rate tariff means your energy prices can rise or fall in line with wholesale market trends. There's no fixed term, and you can usually switch at any time without penalties.
Key Points:
- You’re free to leave at any time — no exit fees.
- If you don’t actively choose a new tariff when your contract ends, you’ll automatically be moved onto a standard variable tariff.
- This is often the default option for new movers or customers who haven't switched in a while.
Ideal for: Flexibility, or for those waiting for better fixed deals to return.
Final Tip: Fixed and variable tariffs — just like dual and single fuel — both have their pros and cons. The best choice depends on your energy usage habits and risk tolerance. That’s why comparing your options is the smartest move.
Use our platform to check the latest tariffs from trusted UK suppliers, and filter results by contract type, fuel type, and more.
Green Energy Tariffs and Renewable Energy Suppliers in the UK
What Is a Green Energy Tariff?
A green energy tariff means the electricity you pay for is matched by energy generated from renewable sources, such as wind, solar, or hydro power. Some tariffs are 100% renewable, while others are a mix of green and conventional sources.
Even with a green tariff, your electricity is delivered via the National Grid, just like standard electricity. The key difference lies in how your supplier sources and replaces the energy you use.
How Much of the UK’s Energy Is Renewable?
Around 25% of the UK’s electricity is generated from renewable sources. The rest still comes from fossil fuels and nuclear power — though this is gradually changing as the UK moves toward net zero.
What About Green Gas?
Green gas is harder to produce and more expensive than renewable electricity. It’s typically created from organic waste like plants, food, and animal matter.
Some suppliers — like Good Energy — offer a small percentage of green gas (e.g. 6%) in their mix. While not widely available, it's a growing area of innovation.
Learn more about suppliers offering renewable deals in our Green Energy Guide.
Green Energy Suppliers to Consider
There are several UK energy suppliers that specialise in green tariffs. These companies are committed to sustainability and helping consumers reduce their carbon footprint.
- Ecotricity – Offers 100% renewable electricity and invests in new green infrastructure
- Octopus Energy – Provides green electricity as standard and supports solar tech
- Good Energy – Focuses on sustainable energy and green gas inclusion
- E.ON Next – Offers environmentally friendly tariffs and carbon offsetting options
By choosing a green energy supplier, you're supporting the UK's transition to cleaner energy — without changing how you receive your supply.
Final Tip: When comparing energy tariffs, look for labels like 100% renewable, REGO-certified, or carbon neutral to ensure the tariff matches your environmental goals.
Types of Domestic Energy Meters in the UK
Understanding which energy meter you have can help you manage your energy usage, submit accurate readings, and choose the right tariff. Here's a breakdown of the main domestic meter types in the UK:
Standard Credit Meters
These are the traditional meters still found in many UK homes. You use energy first and pay later, usually through monthly or quarterly bills.
- Readings are either submitted manually or taken by your supplier
- Bills are often estimated, then adjusted based on actual readings
- Best suited for customers on credit-based energy tariffs
Smart Meters
Smart meters automatically track and send your energy usage to your supplier, eliminating the need for manual readings.
- Show real-time usage in kWh and pounds
- Help identify energy waste and control costs
- Support dynamic pricing and time-of-use tariffs
As of 2025, the UK government aims to have smart meters installed in:
- 74.5% of residential properties
- 69% of small businesses
Smart meters are free to install and are being offered by most major suppliers.
Smart meters also help track your kWh of electricity in real time, making it easier to monitor your electricity usage and stay on top of energy costs.
Not sure if a smart meter is right for you? Our article to help you decide. What is a Smart Meter and How Does It Work?
Prepayment Meters (Pay As You Go)
Prepayment meters require you to pay for energy before you use it — similar to topping up a mobile phone.
- Common in rental properties or where budgeting is a priority
- You can top up your meter using an electricity key, gas card, or a smart meter. These pay-as-you-go options are common for households looking to control spending or manage debt.
- If your credit runs out, your energy supply is paused until you top up again
While convenient for managing costs upfront, prepayment tariffs can be more expensive per unit than credit-based options.
Final Tip: Your meter type can impact your billing, tariff eligibility, and overall energy costs. When comparing energy prices, check if your current meter supports smart features, or if switching to a different type could offer better savings or control.
You can also use Free Price Compare to filter deals based on your meter type and preferred payment method.
What Are Prepayment Energy Tariffs and How Do They Work?
A prepayment energy tariff — also known as Pay As You Go — allows you to pay for your gas and electricity before you use it, by topping up your meter with credit.
How Prepayment Tariffs Work
- You top up your meter using a key, card, or smart meter
- Credit can be added at PayPoint or Payzone shops, or online via your supplier’s mobile app
- As you use energy, the credit is deducted in real-time
If your credit runs low, you’ll need to top up again to keep your energy supply active. Most suppliers offer emergency credit to help you avoid losing power unexpectedly.
Is Prepay Energy More Expensive?
Prepayment tariffs are often more expensive per unit than standard credit tariffs. You won’t benefit from direct debit discounts, and your options may be more limited.
However, these tariffs can still help you:
- Budget more easily
- Avoid debt by only using what you’ve paid for
- Regain control if you’re clearing past arrears
Can I Switch if I’m on a Prepayment Meter?
Yes — you can still compare and switch energy suppliers, even if you have a prepayment meter.
When switching:
- Use filters to view prepayment-compatible tariffs
- Look for suppliers offering better unit rates or support services
- Consider upgrading to a smart prepay meter to unlock more flexible top-up options
Final Tip: If you’re on a prepayment meter, it’s still worth checking for better energy deals. Use Free Price Compare to explore supplier options and see if switching could reduce your energy costs.
What Is an Economy 7 Tariff and Is It Right for You?
An Economy 7 tariff is a type of electricity plan that offers cheaper rates for seven hours overnight — known as off-peak hours. Electricity used during the rest of the day (peak hours) is charged at a higher rate.
How Economy 7 Works
- You get two electricity rates: a lower rate overnight and a higher rate during the day
- The off-peak period typically lasts 7 hours between 10pm and 8:30am, though exact times depend on your supplier and region
- To benefit, you need to use a significant portion of your electricity at night
Who Is Economy 7 Suitable For?
This tariff works best for households that:
- Have electric storage heaters or electric water tanks
- Charge an electric vehicle overnight
- Use appliances like dishwashers, washing machines, or dryers during off-peak hours
Do You Need a Special Meter?
Yes — Economy 7 requires a multi-rate electricity meter that records your usage during both day and night hours. This is often referred to by its MPAN (Meter Point Administration Number), which helps suppliers identify your tariff and usage.
If you’re unsure, your current bill or meter display will usually indicate if you’re already on an Economy 7 plan.
Is Economy 7 Cheaper?
It can be — but only if you shift at least 40% of your usage to off-peak hours. Otherwise, the higher daytime rates may offset the savings.
Before switching:
- Compare Economy 7 tariffs to standard fixed or variable deals
- Review your usage patterns to estimate potential savings
- Check if your appliances can be scheduled for night use
Final Tip: Economy 7 can offer great savings if your lifestyle fits the off-peak schedule. Use Free Price Compare to check Economy 7 deals and compare them with regular tariffs to see what works best for your home.

Frequently Asked Questions
The Energy Price Cap is a limit set by Ofgem, the UK’s energy regulator, on what suppliers can charge per unit of gas and electricity for households on standard variable or default tariffs. It protects customers from unfair price rises, especially during volatile market conditions, but it does not cap your total bill. What you pay still depends on your actual energy usage.
The current price cap level for a typical dual-fuel household paying by direct debit is £1,720 a year (July–September 2025), rising to £1,755 from 1 October 2025.
The cap is set by Ofgem, the independent energy regulator for Great Britain. Ofgem reviews and adjusts the cap every three months, reflecting changes in wholesale costs, network charges, government levies, and supplier operating expenses. This helps balance consumer protection with the stability of the energy market.
The cap was introduced in January 2019 to protect customers on default tariffs from overpaying. Before it, many households—particularly those who hadn’t switched—were paying much more than necessary. The cap ensures fairer energy tariffs, especially for vulnerable households.
Yes. The cap is reviewed and updated quarterly (January, April, July, October). It can move up or down depending on wholesale energy costs and other factors. Each update sets new per-unit rates and standing charges, which in turn affect your bills.
The cap limits the maximum you can be charged per kWh and for standing charges, but it does not cap your overall bill. Your final bill still depends on how much energy you use. Think of it as a cap on rates, not on spend. That’s why monitoring your usage remains important.
The cap applies to:
- Customers on standard variable tariffs
- Prepayment meter customers (with a slightly different cap level)
- New movers automatically placed on a deemed tariff
If you’re on a fixed-term deal, the cap doesn’t apply until your contract ends. Some dual fuel deals and green tariffs may sit above or below the cap depending on the supplier.
Yes. The cap sets the maximum price suppliers can charge on standard tariffs, but it’s not always the cheapest option. Fixed-rate tariffs and promotional deals are often priced below the cap. Running an energy comparison can highlight cheaper deals and potential annual savings.
If your supplier fails, Ofgem’s Supplier of Last Resort scheme automatically moves you to a new supplier. Your supply won’t be interrupted, and the cap will still protect you from unfair charges. Initially you’ll be placed on a default tariff, which may not be the cheapest. Once the transfer is complete, you can switch to a better tariff.
Not exactly. While Ofgem sets the cap nationally, the actual per-unit rates vary by region due to different network and distribution costs. This means your neighbour in another part of the UK might pay a slightly different rate, even under the cap.
The cap will continue to be reviewed every three months, but its long-term future depends on wholesale costs, government policy, and the UK’s transition to renewables. For now, it offers stability for households, but the average annual cost of energy still fluctuates. Many experts believe fixed-rate tariffs will remain important alongside the cap.
Yes. Support includes:
- Warm Home Discount (£150 credit)
- Winter Fuel Payment (for pensioners, means-tested from 2025)
- Cold Weather Payments (triggered by severe weather)
- Supplier hardship funds, fuel vouchers, or additional support credit for prepayment customers
You may also qualify for extra help by joining the Priority Services Register, which gives tailored support if you’re elderly, disabled, or have specific needs.
Yes. With Ofgem’s current energy price cap at £1720 from 1st July – 30th September 2025, most households on standard variable tariffs are paying more than they need to. Switching to a fixed or cheaper tariff below the cap could save you money and protect you from future rises. Use our comparison to see today’s best deals—it only takes minutes.
The energy price cap is set by Ofgem and limits the unit rates and standing charges suppliers can charge on standard variable tariffs. It does not cap your total bill—your usage still matters. The cap is reviewed every three months to reflect changes in wholesale energy costs. From the 1st of October 2025, the cap for a typical dual-fuel household is £1755 per year. Bills may be higher or lower depending on how much energy you use.
Energy prices are set by Ofgem’s price cap, which is reviewed every three months in line with wholesale costs.
- Right now (July–September 2025) the cap for a typical household paying by direct debit is £1,720 per year.
- From 1 October to 31 December 2025, it will rise slightly to £1,755 per year — an increase of around £35 a year, or £2.93 a month.
- The next price cap update will be announced around 25 November 2025, setting rates for January–March 2026.
Because prices can go up or down, many households choose a fixed-rate tariff. Fixing locks in your price per unit for 12–24 months, giving certainty even if the cap rises again.
- Fixed tariff: Your price per unit of energy stays the same for the length of your contract. This makes budgeting easier and protects you from rises, though you may pay more if prices fall.
- Variable tariff: Your price can go up or down in line with the price cap. This can be cheaper if costs fall, but your bills could rise if the cap increases.
A dual fuel tariff means you get both your gas and electricity from the same supplier. This is usually cheaper and more convenient than separate contracts, and many suppliers offer discounts for dual fuel. You can still switch gas and electricity separately if you prefer.
Switching is simple and free. All you need is:
- Your postcode
- Your current supplier and tariff name (from your bill)
- A rough idea of your usage or what you currently pay
We’ll show you the best deals. Once you’ve chosen, your new supplier handles the switch—it usually takes 5 working days, and you’ll have a 14-day cooling-off period if you change your mind. If the switch takes longer, you’re entitled to £40 compensation.
No. Your gas and electricity stay on throughout. The Energy Switch Guarantee ensures a seamless transition with no break in supply, no new equipment, and no disruption.
Our service is completely free. Suppliers pay us a commission, which doesn’t affect the price you pay. Most switches have no fee. If you’re on a fixed contract and leave early, you may be charged an exit fee—but by law, suppliers can’t charge this if you’re within 49 days of your contract ending.
Yes—if you pay the bills directly, you can choose your supplier. Your landlord only controls this if they pay the energy bills. It’s always worth letting them know, but legally you can switch if you’re responsible for the account.
When you move:
- Take a meter reading on the day you move out.
- Tell your current supplier to close the account.
- At your new home, you’ll be placed on a “deemed” variable tariff by the existing supplier. Compare and switch as soon as possible—you don’t have to stay with them.
- If you owe money for more than 28 days, your supplier may stop you switching until you’ve paid.
- If you’re on a prepayment meter and owe less than £150, you can usually switch, and your debt will move to your new supplier.
If you’re struggling, speak to your supplier—they must offer payment plans and may have hardship funds.
You may qualify for extra help, including:
- Warm Home Discount – one-off £150 credit for eligible households
- Winter Fuel Payment – support for pensioners (means-tested from 2025)
- Cold Weather Payment – extra help during prolonged freezing temperatures for those on certain benefits
- Supplier hardship schemes – many providers offer grants or special tariffs
Check what you’re entitled to and don’t hesitate to ask your supplier for support.
A smart meter automatically sends readings to your supplier and shows you how much energy you’re using. All suppliers are required to offer smart meters by the end of 2025. You can still get one when you switch—if you already have a modern SMETS2 smart meter, it will keep working with your new supplier.
Yes. Many suppliers offer 100% renewable electricity tariffs, often at the same price as standard deals. Some also offset gas emissions. You can filter for green tariffs in our comparison results to find an eco-friendly option.
No. Our service is free for consumers. We earn a small commission from the supplier you choose, but this doesn’t affect your price. You’ll pay exactly the same as going direct.
