Business energy is essentially just gas and electricity for companies but it’s a broad topic that branches out into other areas such as net zero and carbon footprint management.
While commercial heat and power works in much the same way as domestic utilities, there are key differences to understand if you want to optimise your firm’s energy performance.
Here’s a rundown of business energy’s key components and how it differs from domestic.
Sold in bulk: Unlike domestic fuel, commercial energy is sold in bulk rather than on a monthly basis, which means it is cheaper than domestic energy.
Longer contracts: Business energy contracts are generally longer than household contracts, sometimes running up to five years, with no cooling-off period.
Single-fuel only quotes: While gas and electricity is sold bundled together to households, business gas and electricity are sold as standalone plans.
Bespoke deals: When a business takes out a commercial energy deal, the plan is sold bespokely and tailored to their needs and usage requirements.
Free health checks available: Commercial energy advisers provide free, no-obligation health checks for businesses so they can find out whether switching suppliers is in their interest and whether their energy efficiency can be improved.
Business energy prices are determined by market conditions, namely supply and demand and the cost of global gas prices. Suppliers will then assess the business in question individually and decide what to charge based on the factors highlighted in this table.

Impact & Key Supplier Checks |
|
Business Size |
Suppliers categorise firms as Micro, Small, or Medium/Large. Larger businesses often access lower unit rates (kWh) due to buying power, but may face higher daily standing charges. |
|
Annual Usage |
Your total consumption (kWh) dictates your "bracket." High-usage businesses are often offered bespoke prices, while low-usage firms may be placed on standardized "matrix" rates. |
|
Industry & Usage Profile |
Suppliers check when you use energy. Businesses operating during off-peak times (evenings/weekends) often secure lower rates than those operating 9-to-5, Monday to Friday. |
|
Contract Type |
Fixed-rate deals offer protection against market spikes. Variable or Rollover rates are typically the most expensive, often costing 33% more than a negotiated fixed deal. |
|
Geographic Location |
Regional costs vary based on the local distribution network. For example, businesses in the Midlands often see lower prices than those in North Scotland due to ease of supply. |
|
Credit Score |
Suppliers perform a commercial credit check. If a business has a lower score, the supplier may request a security deposit or apply a "risk premium" to the unit rates. |
|
Meter Type |
Larger firms using over 100kW of electricity require a Half-Hourly (HH) meter, which provides more accurate data and allows for more complex, precision-based pricing. |
If you move into a property without a pre-arranged contract, you will likely be placed on deemed rates. These are significantly more expensive than negotiated tariffs. You should contact a broker or supplier immediately to move onto a fixed-term contract and avoid these high out-of-contract costs.
While it is possible to compare rates, most suppliers will block a switch if there is an outstanding debt on the account. It is generally recommended to clear any arrears or agree on a repayment plan before attempting to transition to a new provider.
Many UK suppliers now offer dedicated renewable energy tariffs. Providers like Octopus and EDF offer green options and sustainable initiatives, including EV charging support and solar energy integration. A broker can help you perform a whole-of-market comparison to find the most cost-effective green tariff.
THINK CAREFULLY BEFORE SECURING OTHER DEBTS AGAINST YOUR HOME. YOUR HOME MAY BE REPOSSESSED IF YOU DO NOT KEEP UP REPAYMENTS ON A MORTGAGE OR ANY OTHER DEBT SECURED ON IT.
IF YOU ARE THINKING OF CONSOLIDATING EXISTING BORROWING YOU SHOULD BE AWARE THAT YOU MAY BE EXTENDING THE TERMS OF THE DEBT AND INCREASING THE TOTAL AMOUNT YOU REPAY.
