Introduction to Comparing UK Energy Suppliers

Comparing UK energy suppliers is a smart way to save money and ensure you’re getting the best possible service for your home or business. With dozens of gas and electricity companies competing for your custom, regularly reviewing your options can help you find lower prices, better customer support, and tariffs that suit your lifestyle.

UK law gives you important rights when switching energy suppliers. Under rules set out by Ofgem, the energy regulator, you have the freedom to choose your supplier and switch without penalty once your contract ends or if you’re on a standard variable tariff. Suppliers must make the switching process straightforward, and you’re protected against being left without supply during the changeover.

This page will guide you through the essentials of comparing both gas and electricity suppliers, helping you understand your rights, what to look for in a contract, and how to avoid common mistakes. If you’re new to the process or want to brush up on the fundamentals, our overview of gas and electric basics is a great place to start.

Before you begin comparing, it’s helpful to review your current energy usage and needs. This will make it easier to spot deals that genuinely save you money or offer features that matter most to you. As you explore this page, you’ll find links to more detailed information on major energy suppliers and related topics, supporting you to make confident, informed choices about your energy supply.

How to Compare Energy Suppliers in the UK

Comparing energy suppliers in the UK is a straightforward process that can help you save money and find a deal that suits your needs. Here’s a step-by-step guide to help you get started:

  • Gather Your Current Usage Information: Start by checking your latest energy bill. Look for details on your current tariff, unit rates (the price you pay for each unit of gas or electricity), standing charges (the daily fee you pay regardless of usage), and your typical monthly or annual usage. Having this information ready will make it easier to compare offers accurately.

  • Compare Prices and Tariffs: Use official comparison tools to see what different suppliers are offering. Look beyond just the headline price – focus on the unit rates, standing charges, and any discounts that may apply. Ofgem, the UK’s energy regulator, requires suppliers to clearly display these details, making it easier to compare like-for-like.

  • Consider Key Contract Features: Pay attention to the length of the contract and whether it’s a fixed or variable tariff. Fixed tariffs lock in your rates for a set period, offering protection from price rises, while variable tariffs can go up or down. Check for any exit fees if you decide to leave your contract early.

  • Look for Green Energy Options: If reducing your carbon footprint is important to you, check whether suppliers offer renewable energy tariffs. Many providers now supply electricity from renewable sources, and some also offer green gas options.

  • Assess Customer Service and Reputation: Good customer service can make a big difference, especially if you need help with billing or have a complaint. You can check supplier ratings and reviews to get an idea of their reputation.

  • Check Official Recommendations: Ofgem regularly publishes guidance and recommendations to help consumers make informed choices. Make sure any comparison tool you use is Ofgem-accredited for accuracy and reliability.

Once you’ve compared your options and found a suitable deal, you may want to learn more about switching energy supplier or get detailed advice on choosing your energy tariff. Taking these steps can help you secure the best deal for your household while staying informed about your rights under UK energy regulations.

Your Rights When Switching Energy Suppliers

When switching energy suppliers in the UK, you are protected by clear legal rights designed to make the process simple and fair. Under rules set by Ofgem, the energy market regulator, you have the right to switch suppliers freely – there are no charges for switching, and your gas or electricity supply must not be interrupted during the changeover.

Typically, the switching process takes about five working days, although it can take a little longer if you request a later date. Throughout, your new supplier must provide clear, accurate information about your contract, including any exit fees or notice periods. You have a 14-day cooling-off period to change your mind after agreeing to a new contract.

To understand your full consumer rights when switching energy suppliers, including protections around billing and complaints, visit the relevant guidance. For a step-by-step overview of switching, see Ofgem.

If you encounter problems – such as delays, unexpected charges, or issues with your final bill – you should first contact your supplier. If the issue isn’t resolved, learn how to complain about an energy company and what steps to take next. This ensures your rights are upheld throughout the switching process.

What to Look Out For in Energy Contracts

When comparing energy contracts, it’s important to understand the key terms and conditions before signing up. One of the first things to check is whether the tariff offers a fixed or variable rate. Fixed rate tariffs lock in your unit price for a set period, while variable rates can go up or down depending on the market. Each has its pros and cons – read more about fixed vs variable rates to see which might suit your needs.

Pay close attention to the contract length. Many deals last 12 or 24 months, and leaving early could mean paying an exit fee. Early termination fees can be costly, so always check the terms if you think you might need to switch before the contract ends.

Be wary of seemingly attractive discounts or offers. Sometimes, discounts only apply for a short period or come with conditions that can be easily missed. Always read the fine print to avoid surprises.

If you’re interested in renewable energy, check whether the tariff uses green electricity or gas, and understand if this affects the overall cost. Some green tariffs might be more expensive, while others are competitively priced.

It’s also important to consider if the tariff matches your household’s usage pattern. For example, some tariffs are better for high evening use, while others suit steady, all-day consumption.

If you ever face issues such as unexpected charges or unclear bills, see our guide on problems with your energy bill for help resolving disputes. And if you believe you’ve been overcharged, find out how to claim back credit from your supplier.

By carefully reviewing the contract details and understanding your rights under Ofgem’s regulations, you can avoid common pitfalls and choose the best energy deal for your needs.

Common Pitfalls and How to Avoid Them

Switching or choosing a new energy supplier can help you save money, but it’s important to be aware of common pitfalls. Many consumers run into issues such as unclear pricing, hidden exit fees, or misleading marketing that promises savings which don’t materialise. Always check whether the advertised rate includes all charges and whether discounts are conditional.

Before signing up, carefully review the contract terms. Pay particular attention to the length of the contract, any early termination charges, and how price changes are handled. Under the Gas and Electricity (Consumer Complaints Handling Standards) Regulations 2008, suppliers must provide clear information about terms and conditions, so don’t hesitate to ask for details if anything is unclear.

After switching, monitor your bills closely for the first few months. Mistakes can happen during the transfer process, such as incorrect meter readings or delays in closing your old account. Spotting errors early makes it easier to resolve them quickly.

If you do experience problems with your energy supply or supplier, there are steps you can take to resolve disputes and ensure your consumer rights are protected. Being informed and vigilant will help you avoid unnecessary costs and stress when switching energy providers.
