Compare the UK's Top Business Energy Suppliers

Companies now have a huge range of choice when it comes to switching business energy suppliers.

This can make it particularly difficult to decide what is best for your business. Many just choose one of the traditional ‘Big Six’.

The truth is that better deals could be available with some of the newer, independent suppliers.

Large Business Energy Suppliers

Most people in the UK will be well aware of the “Big Six” energy suppliers. Over the years, a number of energy suppliers have challenged the traditional “Big Six”. One of the largest suppliers to do this is OVO Energy, which now serves almost 5 million customers.

When comparing business gas & electricity suppliers, many customers feel more comfortable switching to a larger supplier. The long-established service of a large energy supplier can offer business customer consistency and certainty. However, it’s important to remember that they won’t necessarily offer the best deals on the market.

Independent & Small Business Energy Suppliers

Over recent years, independent and small business energy suppliers have grown in popularity. This has led to many businesses choosing to leave the traditional big six for an independent commercial energy supplier.

As they carry lower overheads than many of the larger suppliers, smaller suppliers can offer some of the best rates on the market. Despite this, when the market is unstable, many businesses are concerned about the risk of their supplier going out of business.

However, you should keep in mind that your business will be protected by the Ofgem safety net. If your supplier was to go bust, Ofgem will provide a new supplier for you with no disruption to your gas and electricity supply. Once you’ve been moved to an alternative supplier, you would be free to compare business gas and electricity suppliers.

    Ofgem will now appoint a new supplier for you, who will contact you soon.

    In the meantime, sit tight, take a meter reading and wait until the supplier we appoint gets in touch.

  • Can I Stay With The Same Energy Supplier?

    In some cases, we can negotiate a better business energy deal with your current supplier. This means you can continue to receive your energy supply from the same provider without switching.

    You should regularly compare business energy suppliers to make sure you're getting the best deal available. Our experts can help you find competitive rates, even if it means sticking with your current supplier.

  • How Long Does It Take To Switch To A New Business Energy Supplier?

    Once we start the switching process, it usually takes around five working days, thanks to OFGEM's Faster Switching guarantee.

    We'll inform both your new and old business energy supplier and get things moving as quickly as possible. The process can be delayed if you have not supplied all the information needed to your new supplier.

  • How Do Business Energy Suppliers Calculate Bills?

    When calculating the cost of business energy bills suppliers take in to account a number of factors;

    Standing Charge: This is a flat, fixed rate charge which applies to all energy bills whether they are domestic or business and it is a charge you will pay regardless of your level of energy consuption.

    kWh Unit Rate x Consumption: This covers the actual amount of energy you use and is simply kWh usage multiplied by your kWh unit rate.

    VAT: A VAT rate of 20% is applied to all business energy bills.

    Levies and/or Discounts: Some business energy customers may also have additional charges/levvies and or discounts applied to their bills. One common levy on business energy bills is the Climate Change Levy and one common discount is the Energy Bill Discount Scheme (EBDS).

  • Can I Get a Dual Fuel Contract for My Business?

    In short, no. Dual Fuel contracts are not common for business energy which means you will need a seperate contract for each fuel type with your business energy supplier.

  • How Can I Reduce My Business Energy Bills?

    Reduce Usage: The primary way to reduce the amount you pay for business energy is to reduce the amount of energy you use. This could be achieved by training staff to adopt for energy conscious practices such as switching monitors and lights off when not in use, especially overnight.

    Run A Business Energy Audit: If you're stumped for ideas on how to reduce usage or become more efficient then undertaking a business energy audit is advisable. This process will highlight where your business uses the most energy as well as where is wastes to the most.

    Compare Current Supplier Prices: As with any billable service, comparing current pricing to check you are getting the best possible deal is one of the best ways to save money on your current business energy bills.

    Leverage Modern Technology: These options can range from the installation of a smart meter which will help you better track when, where and how much energy is used across your business and you could also invest in energy saving infrastructure such as sensor activiated light switches which ensure the lights are only on in a room when a person is present.

  • Have Opus Energy Closed Down?

    In January 2023, Opus Energy announced that they would no longer be trading within the gas market, and all existing gas customers are to be moved to EDF Energy.
