Compare Business Gas & Electricity Suppliers

Currently, the ‘Big Six’ energy suppliers account for approximately 70% of the current market share.

However, the range of gas and electricity suppliers is increasingly expanding, and there are several alternative smaller independent suppliers to choose from. These smaller companies often offer cheaper deals.

If you are a business owner, you could benefit from switching to a cheaper business energy supplier with a more competitive pricing plan for your fixed-term energy contract as this could help you save costs.

Comparing energy suppliers and tariffs are the key to getting the best deal for your business energy. In this guide, we’ll provide you with all the information you need to make a well-informed choice.

Comparing Business Gas Suppliers

When choosing a gas supplier for your business, it is important to consider all the options available to you to help you make the best choice. Ideally, you want to select a deal that meets all your business needs at a low rate.

At Business Electricity Prices, our experts can negotiate with business gas suppliers on your behalf to ensure you have access to great business gas prices .

As there is no one cheapest energy deal for all businesses, it’s important to compare as many suppliers as possible before signing up to a new contract. With Business Electricity Prices, you can quickly compare a wide range of suppliers and tariff types to ensure you are on the best deal for your business.

Compare Business Electricity Suppliers

Similar to the process of choosing a gas supplier for your business, you’ll want to select an electricity supplier that offers you the lowest rate possible for the electricity supply required for your business.

If it’s been a while since you’ve switched business electricity suppliers or renegotiated your contract, you are likely to be on your suppliers’ default tariff. Energy regulator Ofgem has found that the unit rates on these default tariffs can be 50% higher than negotiated contracts.

At Business Electricity Prices, we will ensure you find the best deal to suit the size of your business, your consumption levels and your business meter type.

Whether you run a micro business or a high consumption business with half hourly metering, you can reduce your business electricity costs by comparing business electricity suppliers today.

Which Business Energy Supplierrs can I switch to?

There is now a huge range of choice when it comes to switching business energy suppliers. There are more than 50 providers on the market supplying gas and electricity to businesses.

Choosing the right supplier can be difficult. Without an experienced energy broker on your side, you may need to go from supplier to supplier comparing prices. At Business Electricity Prices, we aim to make the process of comparing energy suppliers simple.

Here, you can find information on some of the leading business energy suppliers. With us, you can compare suppliers from the big six, to independent and green energy suppliers.

Independent Business Energy Suppliers

The popularity of independent suppliers has grown in recent years and they are often found to be some of the best-rated providers on the market.

Some examples of independent energy suppliers in the UK are:

Small Commercial Energy Suppliers

As the business energy market has grown, the number of small suppliers offering business gas and electricity tariffs has increased rapidly.

Due to carrying lower overheads than many of the larger suppliers, small business providers often offer some of the best rates available. Despite this, some businesses are concerned about the risk of a smaller energy supplier going out of business.

However, there is little reason for businesses to be concerned. Many small business electricity suppliers have been operating for many years. For example, Corona Energy was founded in 1995 and continues to supply around 15,000 small and medium-sized businesses.

If a supplier does go out of business, Ofgem’s safety net process passes your supply to an alternative supplier. There would be no interruption to your gas or electricity, and you would be free to stay with your new supplier or switch to a new energy deal.

Here, you can find some examples of small business energy suppliers in the UK:

What Should I Consider When Choosing My Business Energy Supplier?

Selecting a business electricity supplier is an important decision as it can influence your business’ overheads and savings. You can make a well-informed decision by considering the following:

1. Your Business’ Needs

If savings are your priority and you have no loyalty to any specific company, then you should simply select the cheapest tariff from your  business electricity quotes.

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

Standard commercial electricity supplier contracts usually have fixed prices for one year, but some companies offer products to 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 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. It’s likely that only the larger suppliers can offer multi-site discounts.

Tips For Getting The Lowest Supplier Prices

As soon as you receive your renewal offer letter, you can start to compare new quotes from the whole energy market.

Use these tips to get the lowest price for your business:

  • Tip 1: You could save money by changing your meter from one that uses one tariff at all times to a meter that charges differently during the night or at weekends.
  • Tip 2: Never accept a renewal offer because there will always be a cheaper alternative.
  • Tip 3: Use a comparison site or a business energy broker that can compare all suppliers so that you can choose from the whole market.
  • Tip 4: The smaller independent energy providers often have lower rates than the “Big Six”, and it’s wise to include them in your search.
  • Tip 5: A Smart Meter is unlikely to save you money, but installing one ensures your bills are always accurate and you never have to take meter readings.

The majority of new contracts for small businesses include a unit price plus a daily standing charge. You’ll typically pay a daily rate of 25p plus a unit price of between 14p and 18p depending on your location and the supplier you use.

Commercial Vs Domestic Suppliers

Both the rate structure and contract lengths differ for commercial organisations versus domestic users. Businesses all pay VAT at 20%, where 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 end date, although in some cases you may terminate your contract with some financial penalties.

Commercial Energy Suppliers for Large Businesses

Only a handful of energy companies 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 energy 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.

Commercial Energy Suppliers for Small Businesses

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

There are several business electricity and business gas providers who 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 energy 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 who 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 energy suppliers, compare the latest energy tariffs with Business Electricity Prices.

Business Gas and 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 energy company.

  • 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 energy 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 Energy 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.
