What You Should Look For in an Electricity Supplier

Remember -- there’s no such thing as a perfect energy supplier. Factors such as the location, energy usage, and size of your business can influence whether a certain supplier will be the ideal choice. That’s why it is crucial to compare business electricity providers before switching suppliers.

#1 Reputation and Years in the Industry

Energy providers that have been in the industry for years know what they’re doing. When searching for the best business electricity supplier, it’s important to gauge whether they have the expertise. Additionally, consider the company’s reputation. Are they responsive? Do they take complaints seriously? One way to determine this is by reading customer reviews.

#2 Rates

Energy suppliers typically offer a fixed-rate energy plan and a variable rate plan. Under a fixed-rate energy plan, your rate remains unchanged throughout your contract. On the other hand, under a variable-rate plan, your rate changes according to the current market price. This means that when prices go up, so does your rate.

#3 Length of Contract

Another factor to consider is the length of the contract. Whether you choose a six-month or a thirty-six-month contract is entirely up to you, but keep in mind that short-term plans are often more expensive than long-term ones.

Five Common FAQs About Business Electricity


#1 How much do U.K. businesses spend on energy each year?

On average, medium-sized businesses use 35,000-kilowatt-hours of electricity each year. On the other hand, large businesses consume around 90,000-kilowatt-hours of electricity. Small or micro-businesses tend to use anywhere between 15,000 and 25,000-kilowatt-hours of electricity per year.

#2 Is business electricity more expensive than domestic electricity?

It depends. Since business customers will use more electricity than non-domestic customers, energy providers tend to charge lower rates for business electricity. However, businesses will have to pay a higher value-added tax (VAT) of around 20% -- that’s 15% higher than the 5% VAT charged for domestic users.

Additionally, domestic customers are subject to price caps, which means that they never have to pay above a predetermined amount. There are no price caps in place for business customers, hence, they may be more expensive.

#3 Do you need a business electricity contract if your home is being used for business?

The answer is no, provided that not more than 40% of the electricity is used for business. This means that if you go beyond the de minimis threshold of 33-kilowatt-hours per day or 1,000-kilowatt-hours per month, you may have to sign a business electricity contract. If you’re unsure about your usage, it’s best to consult the experts at Watt Utilities. Our team will be able to help determine the best course of action for your situation.

#4 What is the VAT for business electricity?

Businesses pay 20% VAT for their electricity use. However, this does not apply to the following:

  • Home-based businesses where 60% of their electricity use is for domestic purposes
  • Charitable organizations funded by donations and/or grants
  • Businesses that do not exceed the de minimis amount of 33 kWh per day

In such cases, businesses will have to pay only 5% VAT.

#5 How much do small businesses pay for electricity?

To calculate how much a small business would have to pay for electricity each year, simply use the following equation:

Energy use * price per kWh + daily standing charge * 365

For instance, a small business using 10,000 kWh per year, at a standard £0.14/kWh, with a daily standing charge of £0.50 p would have to pay £1582.5 annually.

FAQs About Switching to the Best Business Electricity Supplier


#1 What information does Watt Utilities need to switch me to a new business electricity supplier?

We will need information about your business and your current energy contract, such as:

  • Details about your business (e.g. name, location, industry, etc.)
  • Average electricity usage of your business in kWh
  • Your current energy supplier’s name
  • Your current tariff’s end date
  • Your MPAN number

Most of this information can be found in your electricity bill.

#2 Will my business electricity supply be interrupted during the switch?

Not at all. At Watt Utilities, we will facilitate the switch from start to finish. Once we’ve notified your old supplier that you’ll be switching suppliers, your new supplier will take over. You will experience zero disruptions throughout the entire process.

#3 How long does it take to switch business electricity suppliers?

Suppliers that have signed up to the Energy Switch Guarantee have twenty-one days or three weeks to complete the switch. However, some suppliers may wait until the end of the fourteen-day “cooling off” period to initiate the switching process. The process may take longer if your new supplier does not have the details they need.

#4 Can I switch electricity suppliers if my business is moving?

If you’re planning on moving your business, whether to a co-working space or an entire office building, you need to find out who supplies the electricity to the property you’re transferring to. Then, you should change the account name to your business name.

Don’t forget to take the meter reading at your old premises before you move, as you will still have to pay your outstanding bills.

#5 What is green business electricity?

Green electricity is eco-friendly electricity. It refers to renewable sources of energy such as solar, wind, hydro, biogas, and more. Green energy does not produce harmful greenhouse gas emissions, unlike ‘traditional’ sources of energy such as coal and oil. If you’re thinking of going green, there are plenty of tariffs that may be available to you. Ask the experts at Watt Utilities to learn more.
