# Business energy costs and solutions

UK business owners face a complex and often challenging energy landscape. Rising costs, intricate contract structures, and the imperative to embrace sustainability demand a proactive approach to energy management. While Fuse Energy currently focuses on residential energy supply, its long-term mission is to rebuild the energy system for a future with abundant, clean, and cost-effective energy for everyone.

## Understanding the UK business energy market

The UK business energy market operates distinctly from the domestic sector, presenting unique challenges and opportunities for commercial entities. While the energy itself is the same, the framework governing its supply to businesses is fundamentally different.

### Key differences from domestic energy

Unlike household energy consumers, businesses in the UK are not protected by Ofgem's energy price cap, meaning their tariffs are uncapped and directly exposed to market fluctuations. This absence of a price cap can lead to significant cost increases when fixed-rate contracts expire, particularly if businesses roll onto variable tariffs or renew at an unfavourable time. Business energy prices are typically tailored based on factors such as consumption, contract length, location, meter type, industry, and credit profile, rather than being standardised.

Furthermore, businesses generally pay the standard 20% VAT rate on their energy, compared to the reduced 5% rate for domestic consumers. Some smaller businesses may qualify for the reduced 5% VAT rate if their consumption falls below specific thresholds, such as not exceeding 1,000 kilowatt hours (kWh) of electricity or 4,397 kWh of gas per month. However, this is not applied automatically and requires direct communication with their supplier. Business contracts also tend to be longer, often spanning one to five years, and typically lack the 14-day cooling-off period afforded to domestic customers.

### Market dynamics and volatility

The UK business energy market is significantly influenced by wholesale energy prices, which can be highly volatile. Global market dynamics, including geopolitical tensions, supply disruptions, and commodity market movements, directly impact these prices. Weather patterns also play a crucial role, with severe winters increasing heating demand and driving up gas prices, while mild weather can lead to oversupply and lower rates. This constant fluctuation makes strategic timing for contract renewals essential for businesses looking to secure favourable rates.

## Types of business energy contracts

Navigating the various business energy contracts is crucial for securing a deal that aligns with operational needs and financial strategies. Each type offers different levels of price certainty and flexibility.

### Fixed-rate contracts

Fixed-rate contracts lock in a specific price per unit of energy (kWh) for the duration of the agreement, regardless of market fluctuations. This provides budget certainty and protects businesses from sudden price increases, making them popular with smaller businesses. However, businesses on fixed-rate deals will not benefit if wholesale energy prices drop during their contract term. Fixed-term contracts can range from 12 to 36 months, or even up to five years.

### Variable-rate contracts

Variable-rate contracts, sometimes called 'Freedom' contracts, have unit rates that are linked to market activity, meaning they can increase and decrease throughout the contract duration. While offering flexibility, these contracts expose businesses to market volatility and can lead to unpredictable energy bills. Suppliers typically provide notice of any rate changes, allowing businesses to switch to a fixed-term contract if desired.

### Deemed contracts

A deemed contract, also known as an out-of-contract tariff, is a rolling agreement with expensive rates that suppliers arrange for customers who do not have a formally agreed contract. Businesses often roll onto these rates if they fail to renew their fixed-term contract before it expires. These tariffs are generally among the most expensive options and should be avoided.

> If your business energy contract expires without a new agreement in place, your supplier will typically roll you onto a deemed contract. These out-of-contract rates are usually significantly more expensive than negotiated tariffs, leading to higher energy bills. It is crucial to secure a new contract before your current one ends to avoid these costly rates.

## Key factors influencing business energy costs

Understanding the components that make up a business energy bill is essential for effective cost management. Beyond the unit rate, several other factors contribute to the overall cost.

### Wholesale prices

Wholesale costs represent the price suppliers pay for the raw energy itself. These are the most volatile component of energy bills, influenced by global supply and demand, geopolitical events, and weather patterns. Because gas is widely used in electricity generation, increases in wholesale gas prices can also impact electricity prices.

### Non-commodity charges

Non-commodity charges are costs added to energy bills that are not directly related to the wholesale price of energy. These include network charges for maintaining the pipes and wires that deliver energy, government-LED social and environmental obligations (such as the Renewables Obligation and Feed-in Tariffs), and operating costs of the energy supplier. These charges can be substantial and are often rising.

### VAT and other taxes

As mentioned, businesses generally pay the standard 20% VAT rate on energy, a significant difference from the 5% rate for domestic consumers. Additionally, some businesses may be subject to the Climate Change Levy (CCL), a tax on energy supplied to non-domestic users, which adds to the overall energy bill. Understanding these tax implications is vital for accurate budgeting.

## Strategies for managing business energy

Proactive energy management can significantly reduce costs and enhance a business's resilience against market volatility.

### Comparing suppliers and deals

Regularly comparing business energy suppliers is one of the most effective ways to reduce electricity bills. Many businesses overpay due to outdated contracts or a poor understanding of pricing factors. Switching suppliers before a contract renews can unlock lower unit rates and more favourable terms. Unlike domestic switching, business energy comparison requires detailed analysis of consumption patterns, peak usage, and seasonal variations.

### Improving energy efficiency

Implementing energy efficiency measures is a long-term strategy for reducing overall consumption and demand. This can involve conducting an energy audit to identify usage patterns, investing in energy-efficient equipment (such as LED lighting and modern office appliances), improving building insulation, and using programmable thermostats. Understanding factors like [air source heat pump efficiency](https://www.fuseenergy.com/blog/air-source-heat-pump-efficiency) can also guide businesses towards more sustainable heating solutions. Even small improvements can have a meaningful impact on operating costs.

### Risk management and hedging

In a volatile market, managing risk is paramount. Businesses can adopt strategies like securing fixed-term contracts to provide price certainty. Larger businesses with higher energy consumption might explore flexible purchasing contracts, which allow them to buy energy at various points throughout the contract duration, potentially taking advantage of favourable market conditions. Developing a comprehensive energy strategy that balances cost, risk, and sustainability is key.

## Embracing sustainable business energy

Sustainability is no longer just a corporate social responsibility initiative; it's an increasingly important consideration for business energy procurement, offering both environmental and financial benefits.

### Renewable energy options

Businesses have several options for integrating renewable energy. One of the simplest is switching to a renewable electricity tariff from their supplier, which sources energy from wind, solar, or hydro. For those with suitable premises, installing on-site solar panels can generate electricity, reduce reliance on the grid, and lower energy bills. Wind energy solutions, such as small-scale wind turbines, can also be viable for businesses with appropriate land.

### Carbon reduction initiatives

Beyond direct energy sourcing, businesses can engage in various carbon reduction initiatives. This includes optimising energy usage through smart systems and demand management, which involves reducing consumption during peak demand times. Investing in low-carbon heating solutions like heat pumps can also significantly reduce heating-related emissions. For those considering such upgrades, understanding the [air source heat pump running cost](https://www.fuseenergy.com/blog/air-source-heat-pump-running-cost) is essential for long-term financial planning. Many government incentives and programmes are available to support businesses in adopting energy-efficient and sustainable practices.

### Navigating green certifications

When seeking green energy solutions, businesses should understand certifications and claims. Renewable energy is often backed by UK-certified Renewable Energy Guarantees of Origin (REGOs), which verify that an equivalent amount of energy has been generated from renewable sources. Ensuring suppliers provide transparent information about their renewable energy mix and certifications helps businesses avoid potential greenwashing and demonstrate genuine commitment to sustainability.

## The future of business energy

The energy landscape for businesses is continuously evolving, driven by technological advancements and a growing focus on sustainability.

### Emerging technologies

The future of business energy will be increasingly digital, connected, and data-driven. Smart technologies, such as AI-driven demand forecasting and energy management systems, will enable businesses to optimise consumption and participate in energy markets by trading surplus energy. Advances in energy storage solutions will also play a crucial role, helping to manage the intermittent nature of renewable energy sources. Electrification of transport, heating, and industrial sectors is expected to significantly increase electricity demand by 2050.

### Long-term energy planning

Developing a long-term energy strategy is becoming indispensable for businesses. This involves not just managing immediate costs but also planning for future resilience, compliance with evolving regulations, and aligning with sustainability goals. Businesses will need to be agile, embracing new models of energy consumption and production to stay competitive. This strategic approach helps future-proof operations against market shifts and increasing regulatory demands.

### Preparing for abundance

The UK energy system is undergoing a major transformation, with a significant shift towards low-carbon generation. The government aims for at least 95% of electricity generation to come from low-carbon sources by 2030, with an ambition to deliver a fully decarbonised power system by 2035. This move towards abundant, clean power will reshape how businesses interact with energy, potentially offering more control and opportunities to save or even earn by adjusting consumption patterns through smart controls.
