Your Guide to Small Business Electricity

Whatever company you run, and however many sites you have, the cost of small business electricity will always be significant.

In most instances, gas will be used to heat business premises such as offices, shops or cafes. Electricity, however, is more likely to power equipment, computers and lighting.

For both gas and electricity, you’re still likely to require separate contracts for each. Dual tariff contracts are typically reserved for domestic customers. However, some business energy suppliers may offer you a discounted rate to take both gas and electricity from them.

As a small business, it’s essential to keep your energy bills as low as possible. This is why it’s so important to be on a favourable small business electricity deal.


If your business is classed as a ‘micro business’, the rules on business electricity tariffs are different.

Microbusinesses are businesses that employ fewer than 10 people, with an annual turnover or balance sheet no greater than £2m. You also qualify as a micro business if you use less than 100,000 kWh of electricity a year.

As a micro business, you have more protection from energy suppliers than most larger businesses. There is also far greater flexibility when you switch between energy suppliers.

For businesses that qualify as a microbusiness, energy suppliers are obligated to:

  • inform you of the key terms of the energy plan before you agree to it
  • send you the energy contract with terms and conditions within 10 days, including all renewal terms for fixed term plans
  • include the new contract end date and the latest date that you can give notice to terminate on your bill if you have a fixed term plan.

  • with a credit or debit card
  • direct bank transfer
  • cheque on receipt of a bill

Electricity tariffs for small businesses

There are some significant differences in electricity tariffs between domestic and non-domestic consumers.

For example, business electricity contracts are usually longer, often between two to five years. Moreover, business electricity contract do not come with a set cooling-off period. This makes it difficult to switch suppliers once locked into a contract. Therefore, it’s essential for businesses to ensure they’re happy with the contract they’re on.

Electricity is priced in units. These are known as kilowatt hours, or kWh. Kilowatt hours refer to the power used for a period of time. For instance, a 1kW appliance used for an hour will use 1kWh.

For businesses, the unit prices for electricity are typically cheaper than for domestic energy. On top of this, businesses are able to negotiate on their quotes prices. More often than not, the larger the business, or the more electricity required, the cheaper the rate will be.

A business electricity bill does include other costs within it too. These include:

  • a standing charge
  • VAT (normally at 20% as opposed to 5% charged on domestic electricity bills) 
  • costs to maintain the transmission and distribution network
  • costs towards the Climate Change Levy

The graphic below represents a breakdown of the costs contained within an energy bill.

Tariff types for small business electricity

For small businesses, electricity tariffs are usually either:

  • fixed – the unit price will stay the same throughout your contract
  • variable – the unit price could potentially rise or fall throughout your contract depending on the market

Some business electricity suppliers offer ‘green energy’ tariffs. This tariff will engage more electricity from renewable resources, such as solar power and wind farms.

Some tariffs can also come without a standing charge, so you only pay for the electricity consumed without a daily rate on top.

Deemed and rollover contracts

A deemed contract is enacted when a customer moves into a new site and uses gas or electricity before agreeing to a contract with the supplier.

A rollover contract is also not ideal. They are used if you don’t negotiate a new electricity deal at the end of your current contract. 

Both of these types of tariffs both involve paying very expensive rates for electricity – sometimes upwards of 80%. Avoid these contracts at all costs – they’re a waste of money.

How much does small business electricity cost?

There are many factors which will determine the price that you pay for business electricity. For example:

Type of business: any business that runs outside of peak hours is likely to be offered a lower price for their business electricity from suppliers.

Geographical location: cheaper energy tariffs are usually found in major cities due to scale.

Credit rating: the greater your credit score, the more likely a supplier will offer you a cheaper tariff.

Business size and consumption volume: the more energy that your business uses, the more likely you are going to be able to negotiate for a price that suits you.

Contract length: in some cases, business energy suppliers will offer cheaper prices for longer term business electricity prices.

According to the Department of Business, Energy and Industrial Strategy, non-domestic energy consumers spent the following on their energy:

Very Small Businesses: 17.16 pence per kWh

Small Businesses: 15.43 pence per kWh

Small/Medium Businesses: 14.33 pence per kWh

Medium Businesses: 13.22 pence per kWh

Large Businesses: 12.92 pence per kWh

Very Large Businesses: 11.82 pence per kWh
