Energy is one of the largest ongoing operational costs for many small and medium-sized enterprises (SMEs). Electricity and gas power equipment, heat buildings and keep daily operations running, so the way a business purchases its energy supply can have a direct impact on overall costs.
Energy procurement simply refers to how a business buys electricity and gas. This includes selecting suppliers, choosing tariffs and managing contracts over time.
In practice, many businesses inherit tariffs when they move premises, miss contract renewal windows or remain on outdated deals long after market prices have changed.
This guide explains how energy procurement works for SMEs. It covers common tariff types, contract options, the factors that influence energy pricing and how businesses can approach energy purchasing more strategically through effective planning and business energy comparison.
What Energy Procurement Means for SMEs?
Energy procurement is the process of selecting, negotiating and managing energy contracts for electricity and gas. For SMEs, this usually involves reviewing supplier offers, choosing a tariff structure and agreeing a contract that suits the business’s operational needs.
Unlike large corporations with dedicated procurement teams, many SMEs manage energy purchasing alongside other responsibilities. Limited time and limited visibility of wholesale energy markets can make it harder to assess when to switch suppliers or lock in a new contract.
Electricity and gas for businesses are purchased through commercial contracts rather than domestic tariffs. Prices are influenced by movements in wholesale energy markets, network charges and government policies.
The type of contract chosen affects both cost stability and exposure to market volatility. A fixed tariff can provide predictable pricing, while more flexible arrangements may move with market conditions.
For many SMEs, procurement decisions affect long-term operational costs rather than just the monthly bill.
Why Energy Procurement Matters for Business Costs?
A business energy bill contains several different cost components. Understanding these elements helps explain why procurement decisions can influence overall spending.
Typical components of a business energy bill include:
- Unit rate: The price paid for each kilowatt hour (kWh) of electricity or gas consumed.
- Standing charge: A daily fixed cost applied by the supplier for maintaining the energy supply.
- Taxes and levies: Government-imposed charges such as the Climate Change Levy (CCL).
- Network costs: Charges for maintaining the electricity grid and gas infrastructure.
Even small differences in the unit rate can scale significantly over a year. Businesses operating long hours or using energy-intensive equipment often see the biggest impact from price changes.
Network charges also influence overall costs. For example, electricity bills may include Transmission Network Use of System (TNUoS) charges, which contribute towards the maintenance and operation of the UK’s high-voltage electricity transmission network.
These charges are typically embedded within supplier pricing. Another cost factor is the Climate Change Levy (CCL), an environmental tax applied to business energy consumption.
Businesses that enter a Climate Change Agreement (CCA) with the government – committing to meet energy efficiency targets, may receive a reduction in the CCL rate applied to their energy use.
When contracts expire or are left unmanaged, suppliers may place businesses on higher default tariffs. This often results in energy being purchased at less competitive rates.
Understanding Common Business Energy Tariffs
SMEs usually encounter a few core tariff structures when purchasing energy.
Standard Variable Tariff (SVT)
A Standard Variable Tariff allows the price per unit and standing charge to move in line with the energy market. These tariffs are commonly the default option offered by suppliers and usually have no fixed contract term.
Because prices change with market conditions, SVTs can expose businesses to rising energy costs.
Deemed Tariffs
Deemed tariffs apply when a business moves into new premises without arranging an energy contract with the existing supplier. These tariffs are typically among the most expensive options available and remain in place until a formal contract is agreed.
Out-of-contract Rates
Out-of-contract rates occur when a fixed agreement ends and the business has not renewed or switched suppliers. The supplier automatically moves the account onto temporary rates that are usually higher than standard fixed contracts.
These tariff types are common reasons businesses unintentionally pay more than necessary for energy.
Fixed vs Flexible Energy Contracts
Businesses typically choose between two broad approaches when purchasing energy.
Fixed-term Energy Contracts
Fixed contracts lock in a set unit rate for electricity or gas over a defined period, often between one and three years. This approach provides predictable energy costs and reduces exposure to short-term market volatility.
For SMEs operating on tight margins, predictable pricing can help support budgeting and financial planning.
Flexible or Pass-through Contracts
Flexible contracts track wholesale energy prices more closely. This structure allows businesses to benefit if market prices fall, but it also exposes them to price increases.
Flexible procurement models are more commonly used by larger organisations or businesses with very high energy consumption, as they often require active market monitoring.
Because of the budgeting stability they provide, fixed contracts remain the most common option for SMEs.
Timing Energy Contracts and Renewal Windows
The timing of an energy contract can affect procurement outcomes. Business energy contracts typically last between 12 and 36 months.
Suppliers often open renewal windows several months before the contract end date. This allows businesses to review available options before their current agreement expires.
If a contract is allowed to lapse without renewal, suppliers may move the business onto higher out-of-contract rates.
Reviewing contracts early allows time to compare offers from multiple suppliers and select a more suitable tariff before default pricing applies.
How Energy Usage Affects Procurement Decisions?
Energy procurement is not only about securing the lowest price. It also depends on how a business uses electricity and gas.
Several operational factors influence the most suitable contract structure:
- Operating hours
- Seasonal demand patterns, such as heating in winter or cooling in summer
- Machinery and equipment usage
- The number of premises or operational sites
Different sectors experience different energy demand patterns. Hospitality venues often see peak electricity use during evening service hours.
Manufacturing sites may operate continuously, leading to high and stable electricity demand. Care homes require heating, lighting and equipment running around the clock.
Understanding these usage patterns helps businesses align energy contracts with their operational profile.
The Challenges SMEs Face When Buying Energy
Many SMEs encounter similar challenges when managing energy procurement.
Time is often limited, which makes it difficult to review contracts or track supplier offers. Tariff structures can be complex, with multiple pricing components and contractual terms. Energy markets also change quickly, which means supplier prices can shift within short periods.
Comparing supplier quotes directly can also be difficult because tariffs may include different pricing structures, standing charges or embedded network costs.
For busy business owners, keeping up with these variables can be challenging alongside day-to-day operations.
How Energy Comparison Services Support SMEs?
Energy comparison services help simplify procurement by providing a clearer view of available options.
Typically, these services:
- Monitor electricity and gas prices across multiple suppliers
- Compare tariffs side-by-side
- Translate contract terms into plain language
- Manage the switching process once a deal is selected
For businesses, this approach reduces the time spent analysing supplier offers and helps avoid situations where contracts lapse into higher default tariffs.
Practical Steps SMEs Can Take to Improve Energy Procurement
While the energy market can appear complex, there are practical steps SMEs can take to improve procurement decisions.
- Start by reviewing your current energy contract and noting the renewal date. Understanding when the agreement ends allows time to explore alternative options.
- Check the tariff type and pricing structure applied to your supply. Businesses that have moved premises or allowed contracts to expire may be on higher deemed or out-of-contract rates.
- Analyse your business’s energy usage patterns. Operating hours, equipment and seasonal demand can influence the most suitable contract structure.
- Compare offers from multiple suppliers before renewal windows close. Even small changes in unit rates can affect annual costs.
- Finally, keep records of your MPAN (electricity supply number) and MPRN (gas supply number). These identifiers make it easier to obtain accurate quotes when reviewing suppliers.
Energy procurement is a strategic business decision rather than a routine bill payment. The type of tariff selected, contract structure and timing of renewals all influence long-term electricity and gas costs.
Businesses that regularly review contracts and compare supplier offers place themselves in a stronger position to control overheads.
Working with specialist comparison services can simplify the process, provide visibility across the energy market and reduce the administrative burden of managing contracts.
For SMEs, informed procurement helps maintain predictable operating costs and avoid unnecessary energy expenditure.
