How to Compare Business Energy Contracts

Choosing a business energy contract is about more than finding the lowest electricity or gas unit rate.

For UK businesses, the right energy contract needs to balance price, contract terms, flexibility, supplier service and your business's energy requirements. Comparing contracts properly can help you avoid unnecessary costs and give you greater control over your energy budget.

Whether you run a single site, a multi-site business, a golf club, garden centre, gym, restaurant or another energy-intensive operation, knowing what to look for can make the procurement process much easier.

In this guide, we explain how to compare business energy contracts and the key factors to consider before signing a new agreement.

What is a business energy contract?

A business energy contract sets out the terms under which your electricity or gas is supplied to your organisation.

Unlike domestic energy, business energy contracts can vary considerably in structure. Depending on your business and supplier, you may encounter fixed, variable, flexible, rollover, deemed or out-of-contract arrangements.

The right contract isn't necessarily the one with the lowest headline price. You need to understand what you're actually paying for and what happens throughout the contract term.

Understand your current energy usage

Before comparing business energy contracts, establish how much energy your business uses.

Ideally, review at least 12 months of electricity and gas consumption. This can help you identify:

• Annual electricity consumption in kWh
• Annual gas consumption in kWh
• Seasonal variations
• Peak periods of consumption
• Changes in usage over time
• The number of meters you have
• Your current contract end date
• Your current unit rates and standing charges

Your consumption profile can influence which contracts are available and which procurement strategy is most appropriate.

For example, a business with predictable consumption may have different requirements from a business with significant seasonal fluctuations.

Compare the electricity and gas unit rates

The unit rate is the amount you pay for each unit of energy used, normally measured in pence per kWh.

It is one of the most important figures when comparing business energy contracts, but it shouldn't be considered in isolation.

A supplier offering a lower electricity unit rate may have higher standing charges or other costs. Another supplier may offer a slightly higher unit rate but more favourable overall terms.

Always compare the total expected cost, rather than simply choosing the lowest number on a quote.

Check the standing charge

The standing charge is a daily charge associated with your energy supply.

It can have a significant impact on the total cost of a business energy contract, particularly for businesses with multiple meters.

When comparing quotes, check:

• The daily standing charge
• Whether it is fixed for the contract term
• Whether it differs between meters
• Whether any additional charges apply

A small difference in standing charges can add up over a full contract term.

Look beyond the headline price

A business energy quote can contain several different elements.

Depending on the contract, you may need to consider wholesale energy costs, network charges, government schemes, supplier charges and other costs.

Some contracts may pass certain charges through separately rather than incorporating everything into one fixed unit rate.

This is why two quotes that initially look similar can produce different overall costs.

Always ask for clarity on what is included in the quoted price and what can change during the contract.

Compare fixed and flexible energy contracts

One of the biggest decisions when comparing business energy contracts is whether a fixed or flexible approach is suitable.

Fixed energy contracts

With a fixed-rate contract, the price per unit is generally agreed for the contract period.

The main advantage is predictability. If wholesale prices rise, your agreed unit rate won't automatically increase simply because the market has risen.

However, a fixed contract also means you generally won't benefit from falling market prices during the fixed period.

It's also important to remember that a fixed unit rate doesn't mean your total bill will be fixed. If your business uses more energy, your overall bill will increase.

Flexible energy contracts

Flexible procurement allows businesses to purchase energy in stages or at different points during the contract period.

This can provide greater flexibility and opportunities to respond to movements in the wholesale market, but it also involves more complexity and market exposure.

Flexible contracts may be more appropriate for larger businesses with significant energy consumption and the resources to actively manage their procurement strategy.

Ofgem recognises both fixed and flexible contract structures within the non-domestic energy market.

Check the contract length

Don't automatically assume that a longer contract is better.

A longer agreement can provide greater price certainty, but it also commits your business to a supplier for a longer period.

Before agreeing to a contract, consider:

• How long you expect to operate from your current premises
• Whether your energy consumption is likely to change
• Whether you are expanding or reducing your operations
• Your budget requirements
• Your tolerance for energy price fluctuations

For a growing business, flexibility may be particularly important.

Check the contract's renewal terms

One of the most important details to establish iswhat happens when your contract ends.

Depending on the agreement, you could be moved onto an out-of-contract or deemed arrangement, or the contract could automatically roll over.

Ofgem explains that a business may be placed on a deemed contract if it uses energy without agreeing a contract, while out-of-contract rates can apply according to the terms of the existing agreement.

Make sure you know:

Contract start date, Contract end date, Renewal window, Notice requirements, What happens after expiry

Keeping track of these dates gives you time to review the market and arrange your next contract before the current agreement ends.

Check for exit fees and other charges

Don't overlook the small print.

Some business energy contracts may contain charges or restrictions if you want to leave before the end of the agreed term.

Check the terms for:

• Early termination charges
• Exit fees
• Renewal provisions
• Notice periods
• Payment terms
• Additional supplier fees
• Changes to pricing during the contract

If anything isn't clear, ask the supplier or energy consultant to explain it before you sign.

Consider the energy supplier's reputation

Price matters, but it isn't the only consideration.

A supplier that offers a competitive rate but provides poor customer service can create significant administrative problems.

Before choosing a supplier, consider:

• Customer service
• Billing accuracy
• Complaint handling
• Account management
• Ease of communication
• Online account facilities
• Experience with businesses similar to yours

Businesses should consider the supplier's reputation and the terms of any broker or intermediary arrangement when choosing a business energy contract.

Check the broker or consultant's fees

Using an energy broker or consultant can make comparing business energy contracts easier, particularly if you have multiple sites or significant consumption.

However, you should understand exactly how the service is paid for.

Energy brokers can charge for their services and that fees may be charged separately or included within the supplier bill. Businesses should check what fees apply and which suppliers the broker works with.

Ask:

• How is the service paid for?
• Is there a commission?
• Is a fee added to the energy rate?
• Which suppliers are included?
• What support is provided after the contract is signed?

Transparency is important when comparing energy procurement services.

Consider renewable energy options

For businesses with sustainability targets, renewable energy may also form part of the procurement decision.

Some suppliers offer renewable electricity tariffs or other options designed to support businesses with their environmental objectives.

However, don't assume that a green tariff is automatically the cheapest or most appropriate option.

Consider your sustainability objectives alongside price, contract structure and overall energy strategy.

Compare quotes on a like-for-like basis

This is one of the most important steps.

If you're comparing three business energy quotes, make sure you are comparing equivalent information.

For example:

A quote with the lowest unit rate isn't necessarily the cheapest contract overall.

Why timing matters when comparing energy contracts

You don't have to wait until the final weeks of your existing contract to start comparing business energy prices.

Starting the process early gives you more time to understand your options and monitor the market.

Energy Costs Managed, for example, uses wholesale price monitoring as part of its procurement approach, helping businesses make informed decisions about when to secure electricity and gas rates.

This can be particularly valuable for businesses with significant or complex energy requirements.

What information do you need to compare business energy contracts?

Having the right information available can speed up the procurement process.

You will generally need:

• Your current energy supplier
• Current contract end date
• Recent energy bills
• Meter numbers
• Annual electricity consumption
• Annual gas consumption
• Current unit rates
• Standing charges
• Number of sites and meters
• Any specific sustainability requirements

Having accurate consumption information helps suppliers and consultants provide more meaningful comparisons.

Should you use an energy broker or consultant?

You can approach energy suppliers directly, but comparing the market can become time-consuming, particularly for larger organisations or businesses with multiple sites.

An energy broker or consultant can help compare suppliers, explain contract options and manage the procurement process.

Businesses can use third parties such as energy brokers to help arrange a business energy contract, but recommends checking their experience, fees, supplier coverage and terms before entering into an agreement.

The key is to choose a provider that offers clear pricing, transparent advice and ongoing support, rather than simply presenting the cheapest headline rate.

Don't stop once you've signed the contract

Comparing business energy contracts shouldn't be a one-off exercise.

Once your new contract is in place, continue to monitor:

• Energy consumption
• Energy bills
• Contract rates
• Supplier charges
• Market movements
• Contract end dates

Bill validation can also help identify discrepancies between your agreed contract terms, actual consumption and what you're being charged.

Energy Costs Managed provides business energy bill validation alongside contract sourcing and wholesale price monitoring, giving businesses a more complete approach to managing energy costs.

How to compare business energy contracts: a simple checklist

Before choosing a new contract, ask yourself:

• What is the total expected cost?
• What is the electricity unit rate?
• What is the gas unit rate?
• What are the standing charges?
• Is the price fixed or variable?
• What additional charges apply?
• How long is the contract?
• When does it end?
• What happens when it expires?
• Are there exit fees?
• How does the supplier perform for customer service?
• Are broker or consultant fees included?
• Does the contract support our sustainability objectives?

If you can answer all of these questions, you'll be in a much stronger position to make an informed decision.
