Business Electricity Comparison Jonathan Whiting Last updated on 7 December 2021 14 min read Getting a good price on your electricity is a straightforward way to save your business a lot of money.There are other important things to think about, however, including the electricity tariff you choose and the energy supplier you decide to partner with.Compare like-for-like quotes from as many electricity providers as possible to find the best deal for your business’ needs.All businesses need electricity to operate: coffee shops need electricity to brew warm, delicious drinks, manufacturing plants need electricity to power their machines and offices need electricity to avoid going back to the dark days of a pen and paper. No matter what your business is, there is no denying that electricity is essential for your day-to-day functioning.Because of this, electricity is also one of the biggest overhead costs that companies face. So it’s not hard to see why you’d be interested in reducing the amount you spend on your electricity – after all, you don’t want to be paying more than you need to be. This guide will help you to compare electricity rates, the different tariffs and leading suppliers for your business, so that you can get the best deal on your electricity.In This Guide to Business ElectricityClick on a link to jump to a specific section.01 | Business Electricity Rates02 | Business Electricity Tariffs03 | Business Electricity Suppliers04 | Compare Business Electricity QuotesCompare Business Electricity RatesThe way that business electricity rates are calculated is quite complex. If you look at your latest energy bill, you’ll notice that it is broken down into lots of smaller costs and it can be difficult to understand what they all are. What is the Climate Change Levy (CCL) tax? And why have you been charged VAT? Luckily, there are only two costs that you need to pay close attention to. These are the unit cost and the standing charge.• The unit cost is how much you are charged (in pence) for each kWh of electricity that your business uses.• The standing charge is a daily fee (in pence) that your energy supplier charges you for providing your business with electricity.Unfortunately, business electricity rates are completely bespoke for each business, so it’s difficult to know whether you’re getting a good deal on your electricity without comparing quotes from a handful of energy companies. However, as a guide, if your unit cost and standing charge are lower than the industry averages, you’re probably getting a good deal.Av. Unit Cost (p/kWh)Av.

It’s essentially the pricing structure of your electricity contract with your energy supplier. There are several different electricity tariffs available, so make sure you take a look at all of them to ensure that you choose the right one for your business needs.Flexible TariffsAlso known as a variable or standard tariff, a flexible tariff is often an energy company’s ‘default’ tariff that you’ll be put onto unless you state otherwise. Flexible tariffs are influenced by the wholesale market price of electricity. So if something happens that causes electricity prices to rise, you’ll be charged more for the electricity that you use (i.e. your unit cost will increase). The opposite applies if there is a sudden fall in the market price of electricity.Benefits:✔ If you’re a risk taker, flexible tariffs are a great option because you can benefit from cheap electricity when market prices fall. This could save your business a lot of money.✔ Flexible tariffs are a smart option if you don’t want to be tied down to a contract as they often don't have a fixed length. This means that you’re free to leave your energy supplier at any time and won’t be hit with expensive penalties.Drawbacks:✘ If market prices for electricity suddenly spike, you’ll end up paying unnecessarily high prices for your electricity on a flexible tariff. Your business could therefore be spending a lot of money just to power its premises.Fixed TariffsWith a fixed tariff, the amount you’ll pay for your business electricity stays the same for the entire duration of your contract. This doesn’t mean that you’ll pay a fixed amount for your electricity each month; it simply means that the cost per kWh of electricity will not change, regardless of variations in the market price of electricity.Benefits:✔ Fixed tariffs provide you with protection from sudden price increases in the market price of electricity. This means that they are often the most affordable type of tariff as you won’t be paying unreasonably high prices for your electricity.✔ If you want to better manage your cash flow, fixed tariffs are a good choice as you’ll know exactly what you’re being charged each month for every kWh of electricity your business uses.Drawbacks:✘ When the market price of electricity falls, you won’t be able to benefit from cheap rates for your electricity. This could mean your business is missing out on an opportunity to save money.✘ Fixed tariffs often have an end date, meaning that you are tied into a contract with your energy supplier for a predetermined amount of time (typically between 1 and 5 years). If you want to leave your energy company before your contract expires, it’s likely you’ll be hit with expensive exit fees.Green TariffsAs its name suggests, a green tariff is the most eco-friendly of all tariffs. Opting for a green tariff means that some (or all) of the electricity supplied to your business premises is generated from renewable sources, such as hydropower and wind. In some cases, a green tariff can also mean that your energy supplier will contribute towards environmental schemes on your behalf with the money you used to purchase electricity from them.Benefits:✔ Green tariffs provide a great opportunity for your business to improve its brand reputation by showing your clients and customers that you’re taking steps to reduce your carbon footprint.✔ Green tariffs can be both fixed and flexible in nature – so whatever type of tariff you want, your business can still invest in renewable electricity and sustainability projects.Drawbacks:✘ Although the renewable energy market is growing, it can still be difficult to find energy suppliers that offer green electricity tariffs.Dual Fuel TariffsLike with domestic energy tariffs, a dual fuel tariff for your business means that you get both your electricity and gas from the same energy supplier, rather than having separate contracts for your electricity and gas from different suppliers. Essentially, all the energy that your business uses is combined into 1 contract with a dual fuel tariff. To find out more about gas for your business, visit our guide to business gas.Benefits✔ If you want to manage your energy account better, going for a dual fuel tariff is a good choice as all the information you need can be found in one place, whether it’s on your bills or on your energy supplier’s website.✔ Some energy companies offer special discounts to businesses who enter into an electricity and gas contract with them. This could end up saving you a lot of money on your energy.✔ Dual fuel tariffs can be fixed, flexible or green in nature, meaning you can still enter into one regardless of the specific type of tariff you want.Drawbacks:✘ Very few energy suppliers actually offer dual fuel tariffs for business customers, so you might find it difficult to find one.Which Business Electricity Tariff Is Right for Your Business?When choosing which tariff to go for, it’s all about figuring out what’s right for your business. For example, there’s no point getting tied into a fixed tariff if you’re not intending to stay at your current business premises for very long because you’ll be stung with exit fees if you try to leave the contract early.Here are some things to think about when deciding which electricity tariff is right for your business:• Do you want to benefit from potential falls in the market price of electricity?•How important is it for your business to be powered using green electricity?• Do you want to combine both your electricity and gas supply into one contract?•How much electricity does your business use and does this amount change often?Compare Business Electricity SuppliersIn recent years there has been a huge growth in the number of energy companies operating in the UK. Many small, independent suppliers have started to penetrate the energy market, creating more competition with the long-established, larger suppliers such as E.ON and SSE.
