Choosing the right energy tariff is crucial for businesses as it directly impacts their bottom line. With the variety of options available in the market, understanding business energy tariffs is essential to make an informed decision.

1. Fixed-Rate Tariffs

Fixed-rate tariffs offer businesses stability by providing a fixed price for the duration of the contract. This means that regardless of market fluctuations, the unit rate for energy consumption remains constant.

One significant advantage of fixed-rate tariffs is budget certainty, as businesses can accurately forecast their energy expenses. It allows for easier financial planning and protects against unexpected price increases.

However, if energy prices decrease, businesses on fixed-rate tariffs may end up paying more than necessary.

2. Variable-Rate Tariffs

Unlike fixed-rate tariffs, variable-rate tariffs fluctuate in accordance with market conditions. The unit price for energy consumption can increase or decrease periodically, reflecting changes in wholesale energy prices.

While variable-rate tariffs offer flexibility and the potential for lower prices during periods of market decline, they pose a risk of price hikes during periods of volatility.

Businesses with more tolerance for price fluctuations and the ability to actively manage their energy usage may find variable-rate tariffs suitable.

3. Deemed Rates

Deemed rates come into play when a business occupies a premise without entering into a formal energy contract. In such cases, the energy supplier assigns a deemed rate, which is typically higher than standard rates.

Deemed rates are intended as a temporary solution until a formal contract is established. Businesses should avoid remaining on deemed rates for an extended period, as they are generally more expensive.

It is advisable to negotiate a proper contract with a supplier to secure a more favorable tariff.

4. Renewable Energy Tariffs

In recent years, there has been a growing emphasis on sustainability and reducing carbon emissions. Renewable energy tariffs allow businesses to align their energy consumption with their environmental goals.

These tariffs provide electricity generated from renewable sources such as wind, solar, or hydro power. While renewable energy tariffs may be slightly higher in cost compared to traditional tariffs, they contribute to a greener future and can enhance a company’s reputation as an environmentally responsible organization.

Businesses committed to sustainability should explore renewable energy tariffs as a viable option.

5. Time-of-Use Tariffs

Time-of-Use (TOU) tariffs are designed to incentivize businesses to shift their energy consumption to off-peak periods.

These tariffs offer different rates for energy consumed during peak, off-peak, and shoulder hours. Peak hours usually coincide with high demand periods when energy prices are at their highest, while off-peak hours have lower prices due to reduced demand.

By actively managing their energy usage and strategically scheduling high-consumption activities during off-peak hours, businesses can reduce their overall energy costs. TOU tariffs are particularly beneficial for businesses with flexible operations that can adjust their energy usage patterns accordingly.

6. Multi-Rate Tariffs

Multi-rate tariffs cater to businesses with distinct energy consumption patterns throughout the day. These tariffs offer different unit rates for energy consumed during different time periods.

For instance, a business might have higher energy usage during daytime operations and lower consumption during nighttime.

By segmenting the day into multiple rate periods, businesses can optimize their energy expenditure by paying lower rates during periods of lower energy usage.

Multi-rate tariffs enable businesses to align their energy costs with their operational needs, ultimately improving cost efficiency.

7. Contract Length and Flexibility

When selecting a business energy tariff, it is crucial to consider the length and flexibility of the contract. Fixed-rate tariffs often come with longer contract durations, typically ranging from one to five years.

While longer contracts provide stability, they may lack the flexibility to adapt to changing market conditions.

On the other hand, variable-rate tariffs usually offer shorter contract durations, allowing businesses to switch suppliers or renegotiate terms more frequently.

The choice between contract length and flexibility depends on a business’s risk appetite, market predictability, and desire for cost stability.

Factors Influencing Tariff Selection

A. Seasonal or Time-Based Changes: Some businesses may experience variations in energy usage throughout the year. For example, hospitality businesses may have higher energy consumption during peak seasons. In such cases, it might be beneficial to explore flexible tariffs that align with the business’s seasonal energy demands.

B. Price Fluctuations: Keeping an eye on energy price trends is vital. Businesses can analyze historical price data and consult with energy experts to make informed predictions about future energy costs. By considering market forecasts, businesses can assess whether fixed or variable-rate tariffs would be more advantageous.

C. Regulatory Factors: Businesses need to consider additional charges and levies imposed by regulatory bodies. The Climate Change Levy (CCL) is a tax applied to non-domestic energy use, while Value Added Tax (VAT) is applicable to most energy supplies. Understanding these regulatory factors helps businesses estimate the overall cost impact and select a tariff that optimizes their energy expenditure.

Further Research and Comparison

While this comprehensive overview provides a solid foundation, conducting further research is crucial to identifying the most suitable business energy tariff.

Comparison websites, such as Business Energy Comparison, offer valuable resources and tools to compare tariffs from various suppliers.

These platforms allow businesses to assess and analyze different options, considering factors such as contract duration, price per unit, renewable energy options, and customer reviews.

Through these comparison websites, businesses can find tailored solutions that align with their unique requirements and energy goals.


Understanding business energy tariffs is essential for making informed decisions that align with a company’s goals and financial interests. Fixed-rate tariffs offer stability and predictability, while variable-rate tariffs provide flexibility but come with inherent market risks.

Deemed rates should be avoided, as they are typically more expensive and temporary in nature. Factors such as seasonal variations, price fluctuations, and regulatory factors like CCL and VAT should be carefully considered.

To ensure the best tariff selection businesses can leverage comparison websites like Business Energy Comparison, which offer comprehensive insights and facilitate informed decision-making.

By selecting the right business energy tariff, companies can effectively manage costs, promote sustainability, and contribute to their overall success.
