Introduction to Switching Your Business Energy Supplier

Switching your business energy supplier can be a smart way to reduce costs, access better customer service, or take advantage of more flexible contract terms. Many small businesses in the UK find that regularly reviewing their gas and electricity deals helps them stay competitive and manage overheads more effectively. Whether you’re looking to cut bills or ensure a more reliable energy supply, understanding the switching process is essential.

Before making any changes, it’s important to consider both the practical steps and the legal requirements involved. Business energy contracts often differ from domestic ones – there may be longer notice periods, early exit fees, and specific rules about contract rollovers. The law also sets out certain protections, especially for smaller businesses, to help you avoid unfair terms or unexpected interruptions to your supply. For example, Ofgem, the UK energy regulator, has introduced regulations that give microbusinesses additional rights when switching suppliers.

Knowing your business type is a crucial first step. Your rights and responsibilities can vary depending on factors like your energy usage, number of employees, and turnover. If you’re unsure where your business fits, it’s a good idea to check if your business is a microbusiness. Microbusinesses benefit from extra protections, such as clearer contract information and shorter notice periods.

Switching suppliers isn’t just about finding the cheapest deal. You’ll need to review your current contract, understand any exit fees, and make sure you’re not tied into a fixed-term agreement. It’s also wise to compare the quality of customer service and any additional support services offered. Taking the time to research and plan can help you avoid common pitfalls like accidental contract renewals or supply disruptions.

For a broader understanding of your legal rights and responsibilities when dealing with energy suppliers, see our page on Energy issues for small businesses. This will help you make informed decisions and ensure your business stays compliant with current regulations.

Assessing Your Current Energy Situation

Before you start the process of switching your business energy supplier, it’s important to have a clear understanding of your current energy situation. This helps you make informed decisions, avoid unexpected costs, and ensure a smooth transition.

Reviewing Your Current Energy Usage and Costs

Begin by gathering your recent energy bills and any consumption reports. Look at how much gas and electricity your business uses each month, and take note of seasonal changes – many businesses see higher usage in winter or during peak production periods. Pay attention to your total costs, including standing charges, unit rates, and any additional fees. Analysing this information can help you spot patterns and identify opportunities to save.

If you’re unsure how to interpret your bills or want tips on managing them more effectively, our guide on dealing with your business energy bills provides practical advice for understanding charges and keeping costs under control.

Understanding Your Existing Contract Terms

Before switching, carefully check the terms of your current energy contract. Most business energy contracts are fixed-term agreements, which means you may be tied in for a set period. Review your contract for:

  • End date: When does your current deal finish?

  • Notice period: How much notice do you need to give if you want to switch?

  • Exit fees: Are there any penalties for leaving your contract early?

  • Automatic renewal: Will your contract roll over if you don’t act before it ends?

Under UK law, suppliers must provide clear information about your contract end date and notice requirements on your bills or in your online account. Failing to follow the correct process could result in extra charges or delays, so it’s essential to know your rights and obligations.

Identifying Your Business’s Energy Needs

Every business is different, so consider how your operations affect your energy requirements. Think about:

  • The size of your premises and the number of employees.

  • The equipment you use and its energy efficiency.

  • Your business hours – do you operate mainly during the day, at night, or around the clock?

  • Any plans for expansion or changes in operations that could affect usage.

Understanding your unique energy needs will help you compare suppliers and choose a deal that matches your business profile.

If you’re experiencing ongoing issues with your current supplier or broker – such as billing errors, poor customer service, or disputes – these problems can be a strong reason to consider switching. Learn more about problems with your business energy supplier or broker and how to address them before making a change.

Taking the time to assess your current situation thoroughly will put you in a strong position to find the best energy deal for your business and avoid any legal or financial pitfalls during the switchover.

Comparing Energy Deals and Choosing a New Supplier

Comparing Energy Deals and Choosing a New Supplier

Switching your business energy supplier can help you save money and find a plan better suited to your needs. To make the most of the switch, it’s important to know how to compare energy deals effectively, understand contract terms, and choose a tariff that fits your business.

How to Compare Energy Tariffs and Suppliers

Start by gathering information about your current energy usage and contract. This includes your annual consumption (in kWh), current rates, and contract end date. With these details, you can accurately compare offers from different suppliers.

When comparing deals, look at:

  • Unit rates and standing charges: These are the main costs on your bill. Some suppliers offer lower unit rates but higher standing charges, so check the total estimated cost.

  • Tariff types: Fixed-rate tariffs keep prices stable for a set period, while variable tariffs can change with market rates. Consider which suits your business’s budget and risk tolerance.

  • Contract length: Business energy contracts often last from one to three years. Shorter contracts offer flexibility, while longer ones may lock in better rates.

  • Exit fees: Some contracts charge a fee if you leave early. Make sure you know these costs before signing.

For a step-by-step guide to switching, visit Ofgem, the UK’s energy regulator. Their advice covers everything from comparing suppliers to understanding your rights during the switch.

Understanding Key Contract Terms

Before signing a new contract, review the terms carefully. Pay attention to:

  • Prices and charges: Ensure you understand all charges, including any additional fees.

  • Duration: Know when your contract starts and ends, and whether it renews automatically.

  • Notice periods: Some suppliers require notice before you switch away or your contract ends.

  • Exit fees: Check if there are penalties for leaving the contract early.

Your legal rights and obligations when switching suppliers are protected under UK law. For a comprehensive overview of your rights, including what to expect during the switching process and how to avoid penalties, see this Energy Supply Contracts guide.

Choosing the Right Tariff for Your Business

Selecting the right tariff is about more than just the lowest price. Consider your business’s energy usage patterns, whether you need flexibility, and if you value green energy options. Some tariffs may offer additional benefits, like customer support or energy efficiency advice.

For more detailed guidance on choosing your energy tariff, see our dedicated page.

Where to Find Reliable Information and Comparison Tools

To compare deals, use trusted comparison websites and check supplier reviews. Ofgem provides a list of accredited price comparison tools, ensuring the information is accurate and unbiased. Always double-check contract terms directly with the supplier before committing.

In addition to switching suppliers, you can reduce costs by improving your business’s energy efficiency. For practical tips, see the simplest way to save energy.

By carefully comparing deals, understanding contract terms, and selecting the right tariff, you can make an informed decision that benefits your business both financially and operationally.

The Switching Process: Step-by-Step Guide

The Switching Process: Step-by-Step Guide

Switching your business energy supplier can seem daunting, but following a clear process helps ensure a smooth transition and continued supply. Here’s what you need to know:

1. Review Your Current Contract

Before starting the switch, check your current energy contract for details such as the end date, notice period, and any exit fees. Most business energy contracts are fixed-term, so switching before the contract ends could result in penalties. Look for your contract’s “termination window” – the period when you’re allowed to give notice to switch without extra costs.

2. Compare Energy Deals

Research and compare offers from different suppliers to find the best rates and terms for your business needs. Pay attention to contract length, unit rates, standing charges, and any additional fees. Consider whether a fixed or variable tariff suits your business best.

3. Notify Your Current Supplier

Once you’ve chosen a new supplier, inform your current supplier that you intend to switch. This is usually done in writing and must be within your contract’s termination window. Your current supplier may make a counter-offer, but you’re under no obligation to accept it.

4. Sign Up With Your New Supplier

Agree to a new contract with your chosen supplier. You’ll need to provide details such as your business address, supply numbers (MPAN for electricity, MPRN for gas), and recent meter readings. Your new supplier will handle the switching process and contact your old supplier to arrange the changeover.

5. Switching Timeline and Notifications

The switching process typically takes between 17 and 21 days, including a 14-day cooling-off period for microbusinesses. Your new supplier should keep you updated throughout, confirming your start date and any actions required. You’ll receive a final bill from your old supplier once the switch is complete.

6. Avoiding Supply Interruptions

Switching should not interrupt your energy supply. UK regulations ensure that your gas and electricity will continue to flow during the switch, so there’s no risk of your business being left without power. To avoid delays, make sure you pay any outstanding bills and provide accurate meter readings when requested.

7. Compliance With Legal Regulations

Business energy switches are regulated by Ofgem. Suppliers must follow rules on contract transparency, switching timescales, and customer communication. Microbusinesses have additional protections, such as clearer contract terms and the right to reasonable notice before changes. Always read your new contract carefully and keep copies of all correspondence.

8. If You’re Moving Premises

If you’re switching supplier because you’re relocating, there are extra steps to consider. You’ll need to close your old account, open a new one at your new site, and coordinate the switch to avoid double charging or supply issues. For detailed guidance, see our advice on dealing with your energy supply when you move business premises.

9. If Your Supplier Goes Bust During the Switch

If your current supplier goes out of business while you’re switching, don’t panic. Ofgem will automatically appoint a new supplier to take over your supply, and your energy will not be cut off. You should take a meter reading and keep records of any communications. For step-by-step instructions, see what to do if your energy supplier has gone bust.


By following these steps and staying informed, you can switch your business energy supplier with confidence, avoid unnecessary costs, and ensure your business remains compliant with all legal requirements. If your circumstances change – such as moving premises or dealing with a supplier failure – be sure to review the relevant guidance to keep your business energy running smoothly.

Legal Considerations and Contract Terms

When switching your business energy supplier, it’s important to understand the legal considerations and contract terms involved. Taking the time to review your contract carefully can help you avoid unexpected costs, penalties, or supply interruptions.

Understanding Your Rights and Obligations

Business energy contracts are legally binding agreements between your business and the supplier. Unlike domestic energy contracts, business contracts often have fewer protections, so it’s essential to know your rights and obligations before signing. For example, you’ll be bound by the contract’s terms for its full duration, which can range from one to several years. Breaking a contract early might result in exit fees or other penalties.

If you’re a small business or a microbusiness, you may benefit from additional legal protections. Microbusinesses, for example, have specific rights regarding contract transparency and notice periods. To see if your business qualifies, you can check if your business is a microbusiness.

Spotting Unfair Contract Terms and Hidden Fees

Before committing, scrutinise the contract for any unfair terms or hidden fees. Watch out for:

  • Automatic rollover clauses: Some contracts automatically renew if you don’t give notice. This can lock you into another fixed period, often at higher rates.

  • Termination fees: Check if there are charges for leaving the contract early.

  • Non-transparent pricing: Make sure all costs are clearly stated, including standing charges, unit rates, and any additional fees.

  • Complex terms: If any part of the contract is unclear, ask your supplier for clarification or seek independent advice.

The law prohibits unfair terms that create a significant imbalance between you and the supplier. If you believe a term is unfair, you may be able to challenge it, but it’s best to raise concerns before signing.

Legal Protections for Small Businesses and Microbusinesses

Small businesses and microbusinesses enjoy certain legal safeguards. For instance, suppliers must provide clear information about contract end dates and renewal terms. Microbusinesses are entitled to at least 30 days’ notice before their contract ends, giving you time to compare offers and switch without being rolled over.

Knowing your business’s status is crucial, as it affects your rights. You can check if your business is a microbusiness to understand what protections apply to you.

Reading and Understanding Contract Details

Never rush into an energy contract. Take the time to read all the terms and conditions, including the small print. Pay particular attention to:

  • Contract length and renewal process

  • Notice periods for switching or terminating

  • All fees and charges

  • Payment terms and methods

If you’re unsure how the contract terms will affect your business, especially regarding tariffs and pricing structures, you can learn more by visiting our guide on choosing your energy tariff.

Understanding your legal position and contract terms not only protects your business but also helps you make informed decisions when switching energy suppliers. If in doubt, seek professional advice before committing.

After Switching: Managing Your Energy Supply and Costs

After switching to a new energy supplier, it’s important to manage your energy supply and costs effectively to ensure you get the full benefit of your new deal. Here’s what you need to know about handling your bills, keeping track of your usage, finding support if you need it, and building a positive relationship with your supplier.

Handling Your Energy Bills

Once your new supplier takes over, you’ll start receiving bills directly from them. Make sure you check your first bill carefully – it should reflect your agreed rates and any opening meter readings you provided. If you spot any errors, contact your supplier straight away to resolve them. Setting up a direct debit can often make payments easier and may even secure you a better tariff.

For more detailed advice on paying and managing your bills after switching, see our guide on dealing with your business energy bills.

Monitoring Your Energy Usage and Costs

Regularly monitor your energy usage to ensure you’re making the savings you expected. Many suppliers offer online accounts or apps where you can track your consumption in real time. Comparing your current bills to those from your old supplier can help you spot trends and areas to cut back. Consider installing a smart meter if you haven’t already – this can provide more accurate readings and help you identify energy-saving opportunities.

Getting Extra Support If You’re Struggling

If you find your energy costs are higher than expected or you’re struggling to keep up with payments, don’t wait to seek help. Most suppliers offer support for businesses facing financial difficulties, such as payment plans or advice on reducing usage. You can learn more about your options by reading our information on getting extra support from your energy supplier.

Keeping in Touch with Your Supplier

Good communication with your supplier is key to avoiding issues and making the most of your contract. Make sure you know how to contact them – whether by phone, email, or an online portal – and keep a record of your correspondence. Notify them promptly about any changes to your business or premises, and don’t hesitate to ask questions about your bill or tariff. This proactive approach can help you avoid misunderstandings and ensure you’re always on the best deal for your needs.

Understanding Your Rights and Legal Protections

Your new supplier must comply with rules set out in the Energy Act 2013, which protects businesses when switching suppliers and ensures fair treatment. This legislation covers your right to switch, the information suppliers must provide, and how disputes should be handled. If you believe your supplier isn’t meeting their obligations, contact them first to resolve the issue. If you’re not satisfied, you may be able to escalate your complaint further.


By staying on top of your energy bills, monitoring your usage, seeking support when needed, and maintaining open communication with your supplier, you’ll be well-placed to manage your business energy costs effectively after switching.

Common Issues and How to Resolve Them

Switching your business energy supplier can bring significant benefits, but it’s not uncommon to encounter challenges along the way. Understanding the typical issues and knowing how to address them can help ensure a smooth transition and protect your business from unnecessary disruption or costs.

Potential Problems When Switching Suppliers

Some of the most frequent issues businesses face during or after switching energy suppliers include:

  • Delays in the Switching Process: Administrative errors, incomplete information, or outstanding debts can slow down or halt the switch.

  • Contract Overlaps or Gaps: If your old contract hasn’t ended before the new one starts, you might face double billing or, conversely, a gap in supply.

  • Unexpected Charges: Early termination fees or hidden costs may arise if you leave your contract before its end date.

  • Billing Disputes: Inaccurate final bills or disagreements over meter readings can lead to confusion and financial disputes.

  • Supply Interruptions: Although rare, supply interruptions can occur if there are issues with your account details or meter registration.

For a deeper look at these and other common challenges, see our guide on problems with your business energy supplier or broker.

Handling Disputes and Complaints

If you encounter a problem with your new or previous supplier, it’s important to act quickly:

  • Contact the Supplier Directly: Raise your concern with your supplier’s customer service team. Clearly explain the issue and provide any supporting documents, such as contracts or bills.

  • Follow the Supplier’s Complaints Procedure: All licensed energy suppliers must have a formal complaints process, which should be outlined on their website or in your contract.

  • Keep Records: Document all communications and retain copies of any correspondence or evidence relating to your complaint.

If the issue isn’t resolved within eight weeks, or you’re unhappy with the outcome, you may be able to escalate the complaint to the relevant ombudsman or regulatory body.

When to Seek Legal Advice or Escalate

Some situations may require professional legal guidance, especially if:

  • The dispute involves large sums of money or complex contractual terms.

  • You believe your supplier has breached your contract or failed to meet regulatory obligations, such as those set out by Ofgem or under the Gas Act 1986 and Electricity Act 1989.

  • You’re facing threats of disconnection or legal action.

A solicitor experienced in business energy contracts can help you understand your rights and negotiate a resolution. In some cases, mediation or arbitration may offer a quicker, less costly alternative to court proceedings.

Support and Resources for Small Businesses

Small businesses have several resources available when dealing with energy supplier issues:

  • Supplier Complaints Teams: Your first port of call for most problems.

  • Ombudsman Services: If your complaint remains unresolved, you may be able to seek an independent review, depending on your business size and the nature of the issue.

  • Industry Regulators: Ofgem oversees the energy market and sets rules suppliers must follow to protect business customers.

  • Business Advice Services: Many local authorities and business groups offer support and guidance on managing energy contracts and resolving disputes.
