Who Are The Largest Business Electricity Suppliers?

Many are aware of the dominant reign the ‘Big Six’ had in the UK for many years. Whilst the majority of the originally largest electricity suppliers in the UK still hold a large market share; there have been a few new suppliers gaining momentum. 

Here are the UK’s largest electricity suppliers:

Pulling from rates displayed on our business electricity page, we can review the cheapest suppliers for March 2024. It’s important to remember that these prices are an example based on the consumption of an annual 25,000 kWh of electricity. Regional factors and as wholesale prices change regularly, it is better to start your electricity comparison. Ovo Energy acquired the domestic segment of SSE in 2020 as they now only handle business energy. nPower was acquired by E.ON in 2019. These market shares are for the domestic market and have been rounded up.

What Should I Consider Before I Switch Business Electricity Suppliers?

When you switch business electricity suppliers, you must have all the information you need before you commit to a new tariff. The supplier and tariff type you choose can influence your business’ overheads and savings.

Here, we’ve put together a few tips on what you should consider to help you find the best deals when you switch business electricity supplier.

1. Your Business Needs

If savings are your priority and you have no loyalty to any specific business electricity supplier, then you should simply select the cheapest deal available when you use a business energy comparison engine to compare business electricity suppliers.

However, if you need additional services such as a Smart Meter, help with reducing consumption, or have advanced invoicing requirements, then your selection can become more limited.

You may also want to combine products such as boiler services, so you only have one monthly bill for all services. Check what each supplier can offer you before signing a new contract.

2. How Long You Require Fixed Rates

A standard business electricity contract will usually have fixed prices for one year, but some companies offer products at secure rates for up to five years.

In the outlying years, the price differential between providers increases, so it’s wise to compare more companies if you want a longer-term business electricity contract. Some suppliers offer variable-priced contracts for larger consumers of energy with half-hourly meters.

3. If You are a Multi-Site Business

As your usage increases, your unit price reduces. The same should occur for multi-site quotes which involve grouping all your sites so that you can leverage your buying power and negotiate a packaged deal. Only the larger suppliers can likely offer multi-site discounts.

Our Simple Business Electricity Supplier Comparison Service

We aim to make the process of comparing electricity suppliers as simple as possible. With our 3-step process, you can find the latest deals to keep your bills as low as possible.

Step 1: Compare the latest prices

As soon as you receive your renewal offer letter, you can start to compare new quotes from the energy market. Our energy comparison service gives you access to a wide range of tariffs from our trusted panel of business electricity suppliers.

Step 2: Select your business electricity tariff

All that’s left for you to do is select the right business electricity tariff for you. Our expert team can offer advice on the right tariff type for your business and energy usage.

Step 3: We complete your switch

Our expert team will handle the entire switching process on your behalf, including dealing with your new and old suppliers to arrange your changeover date. There will be no interruption to your business electricity supply, and you can continue to use gas and electricity as normal.

Commercial vs. Domestic Suppliers

Both the rate structure and contract lengths differ for commercial organisations versus domestic users. Businesses all pay VAT at 20%, whereas residential users pay 5%. Companies also pay the Climate Change Levy (CCL).

The majority of contracts are fixed-term plans for between one and five years, although you may be eligible for a flexible or variable-priced plan. Once signed, it’s unlikely you can cancel before the agreement's end date, although in some cases you may terminate your contract with some financial penalties.

Commercial Electricity Suppliers for Large Businesses

Only a handful of providers supply business electricity for those corporations spending over £100,000 per year or consuming over 750,000 kWh. The majority of the new entrants and independent providers concentrate on services for SMEs and micro businesses. If you have a half-hourly meter or meters categorised under the P272 regulations, then check the contract types available to you.

The tender process of getting prices is also more time-consuming as each business electricity supplier produces unique and bespoke business electricity quotes for each site. It can take a week to ten days to get your proposed tariff back. Unless you have a dedicated energy consultant working for your firm, we recommend using a broker to reduce your workload.

Small Business Electricity Suppliers 

If you run a small business or micro business, controlling energy costs and reducing your overheads is vital.

Several business electricity and business gas providers only supply SMEs. They cater their services to offer you the best possible prices. For example, British Gas Lite offers a service to SMEs entirely online in an attempt to keep costs down.

It’s worth bearing in mind that the rules surrounding business electricity renewals are slightly different for small businesses. If you run a micro business, your supplier is required to provide you with a renewal letter detailing your current prices, your renewal prices and your current energy consumption.

You will find that the renewal prices offered are often much higher than negotiated rates. Micro businesses that fail to renegotiate their contract or switch suppliers could face rates 50% higher than those on negotiated terms.

To find out how much you could save by switching business electricity suppliers, compare the latest energy tariffs.

Business Electricity Supplier FAQs

  • Should I Switch My Supplier?

    If you’re happy with the service your energy company provides to you, then there’s no need to change your commercial electricity supplier. Either call them to negotiate an improved deal or ask your broker for new prices. You will still need to switch your gas or electricity contract even if you stay with your current electricity provider.

  • How Much Could My Business Save By Switching Suppliers?

    Savings will depend on factors such as your business’ size, the number of staff, and how efficiently it is run. The more efficient your business is, the more savings you could make.

    If you haven’t switched electricity suppliers or renegotiated your contract rates for a while, it is highly likely that you’ll make savings by switching.

  • How Long Could It Take To Switch Suppliers?

    Typically, it can take around four to six weeks to complete a business gas or electricity supplier switch. Ensure that you provide your new supplier with all the details they need as failing to do so could cause a delay.

  • Could I Leave My Business Electricity Contract Early?

    Fees to terminate an ongoing contract early are usually high, so if you must do this you should ensure that the savings from your prospective new contract compensate for the early exit fees.

  • What Happens If I Do Nothing?

    If you don’t act once you receive your renewal letter, then your prices could move to 'out of contract' rates depending on the terms of your current contract. You could see a three-fold increase in your tariffs until you renew your agreement.

  • Should I Get A Dual Fuel Tariff?

    You could save money by combining your business gas and electricity contract, but it varies depending on your location. It’s best to get quotes for both single fuels and a combined tariff then compare the total price of both options.

  • How Do I Find Out Who My Supplier Is?

    A recent bill should provide the answer. If you can’t find this, then contact your local electricity distribution company.

  • What Are My Meter Numbers?

    Your latest invoices or bills should show all the meters associated with your company locations. You can also find these on the physical meter. Alternatively, a broker can match your address and postcode and locate them.
