For many businesses, an energy contract renewal can feel like an administrative task that only needs attention when the current contract is about to expire. However, leaving your business energy contract renewal until the last minute can mean less time to assess your options, review your energy requirements and make an informed procurement decision.

Whether you run a small business with one premises or manage energy contracts across multiple sites, understanding when to start looking at your next business electricity or gas contract can help you take greater control of your energy costs.

So, when should you renew your business energy contract?

There is no single date that works for every business. The right approach depends on your existing contract, energy consumption, business requirements, contract structure and market conditions. However, one principle applies to almost every business:

Don't wait until your current contract is about to expire before you start thinking about what comes next.

Starting the process early gives you time to review your position, understand your options and decide what is right for your business.

Why timing matters when renewing a business energy contract

Energy is a significant operating cost for many UK businesses. Yet business energy contracts are often renewed with relatively little consideration simply because the process has been left until the last minute.

When you start your renewal process early, you have more time to consider the bigger picture rather than simply looking for a replacement contract.

An early review can give you the opportunity to:

• Check your current contract and pricing.
• Confirm your contract end date.
• Review your electricity and gas consumption.
• Identify changes in the way your business uses energy.
• Compare different contract options.
• Consider whether a fixed or flexible contract is appropriate.
• Monitor wholesale energy market movements.
• Check your existing energy bills for potential errors.
• Review supplier performance and service.
• Consider your future energy requirements.
• Develop a procurement strategy rather than making a rushed decision.

The objective isn't simply to find a new contract. It is to make sure your next energy contract is appropriate for your business.

When should you start looking at your next business energy contract?

The exact timing will depend on your existing contract and circumstances, but businesses should ideally begin reviewing their position several months before their current contract ends.

This gives you time to gather the necessary information, understand your current position and assess your options.

The first thing to establish is your business energy contract end date.

It sounds simple, but businesses with multiple sites, historic contracts or several meters can sometimes find it difficult to keep track of exactly when each agreement ends.

Once you know the contract end date, you can work backwards and allow enough time for:

1. Reviewing your existing contract.
2. Understanding your current energy consumption.
3. Checking your bills.
4. Assessing your future requirements.
5. Reviewing available procurement options.
6. Considering market conditions.
7. Making a decision.
8. Arranging your new contract.

The larger or more complex your business, the more important it is to allow sufficient time.

A business with several premises and multiple energy contracts may need to start the process considerably earlier than a small business with one straightforward contract.

What happens if your business energy contract expires?

One of the biggest risks of leaving your renewal too late is reaching the end of your contract without having arranged a new agreement.

Depending on the terms of your existing contract, your supplier may move you onto a default, deemed or out-of-contract arrangement.

These arrangements can be significantly different from a negotiated business energy contract and may result in higher costs.

This is why your contract end date should be treated as an important business deadline.

Don't assume that your supplier will automatically provide the most competitive option when your current agreement ends.

Your renewal is an opportunity to review your energy requirements and consider whether your existing supplier, contract structure and procurement strategy are still suitable.

Should you automatically accept your supplier's renewal quote?

No not without reviewing your options.

When your current supplier sends a renewal offer, accepting it can appear to be the easiest option.

You already know the supplier, the account is established and changing contracts can seem like unnecessary work.

However, a supplier's renewal offer is not necessarily the best option for your business.

Before accepting a renewal quote, consider whether you have properly assessed:

• The electricity or gas unit rate.
• Standing charges.
• Contract length.
• Payment terms.
• Contract structure.
• Your expected consumption.
• Your business's future requirements.
• Supplier service levels.
• Any additional charges.
• Alternative procurement options.

It's also important to remember that the lowest unit rate does not automatically mean the lowest overall cost.

Your total energy cost depends on your consumption, standing charges, contract terms and other elements of your energy agreement.

A proper comparison should therefore consider the complete contract rather than focusing on a single headline figure.

What should you compare when renewing business energy?

When considering a business electricity contract renewal or business gas contract renewal, there are several factors worth reviewing.

1. Unit rates

The unit rate is the amount you pay for each unit of energy consumed.

It is an important part of your energy cost, but it should be considered alongside the other charges that make up your bill.

2. Standing charges

Standing charges are another important consideration.

A contract with a lower unit rate may not necessarily provide the lowest overall cost if the standing charge or other costs are higher.

3. Contract length

Consider how long you want to commit to your next contract.

The appropriate contract length will depend on your business plans, appetite for price certainty and procurement strategy.

4. Your energy consumption

Your previous energy usage can help inform your next procurement decision.

If your business has grown, reduced its operating hours, changed equipment or moved premises, your historical consumption may no longer accurately represent your future requirements.

5. Contract structure

There are different approaches to purchasing business energy, including fixed and flexible arrangements.

The appropriate option will depend on your business circumstances and how you want to manage price certainty and exposure to wholesale market movements.

6. Supplier service

Price isn't the only consideration.

You should also think about the level of service you receive, including billing accuracy, communication, account management and how effectively problems are resolved.

How do wholesale energy prices affect contract renewal decisions?

Wholesale energy prices are an important consideration when businesses are reviewing their next contract.

Energy suppliers purchase energy in the wholesale market, and movements in wholesale electricity and gas prices can influence the prices available to businesses.

Wholesale prices can move for a wide range of reasons, including supply and demand, geopolitical developments, weather, infrastructure and wider economic conditions.

This means that the market can change while a business is considering its next contract.

However, businesses should be cautious about trying to predict exactly when energy prices will reach their lowest point.

Rather than attempting to perfectly time the market, a more practical approach can be to monitor wholesale market movements and use that information to support a wider procurement strategy.

This is particularly relevant when considering fixed contracts, where a business may want greater price certainty for a defined period.

Regular market monitoring can help businesses make decisions based on current market information rather than simply waiting until their existing contract expires.

Review your energy consumption before renewing

Your energy consumption should form an important part of your contract renewal review.

Businesses change.

You may have expanded your premises, increased production, installed new equipment or changed your opening hours. Alternatively, you may have reduced your workforce, closed a site or changed how your premises operate.

All of these factors can affect how much electricity and gas your business uses.

Before arranging a new contract, consider:

• Has your annual consumption increased or decreased?
• Has your operating pattern changed?
• Have you opened or closed premises?
• Have you installed new equipment?
• Have your production levels changed?
• Are your opening hours different?
• Are you expecting further changes during the next contract period?

Understanding these changes can help ensure that your procurement strategy reflects the business you operate today and the business you expect to operate during the next contract period.

Don't overlook your existing energy bills

Contract renewal is also a good opportunity to check whether your current energy bills are accurate.

Energy bills can contain errors or discrepancies for a variety of reasons.

These can include:

• Incorrect meter readings.
• Estimated consumption.
• Incorrect rates.
• Incorrect standing charges.
• Charges that don't match the agreed contract.
• Unexpected additional charges.
• Issues following a meter change or premises move.

If an issue isn't identified, you could continue paying incorrectly without realising there is a problem.

A business energy bill validation can provide an additional layer of checking and help identify discrepancies that may otherwise be overlooked.

This is particularly valuable for businesses with high energy consumption or multiple sites, where even a relatively small billing discrepancy can have a significant financial impact over time.

What if your business has multiple sites?

Managing a business energy contract renewal becomes more complicated when you have several premises.

Each site may have a different:

• Contract end date.
• Supplier.
• Meter.
• Consumption profile.
• Contract rate.
• Operating pattern.

This can make it difficult to maintain a clear overview of your overall energy position.

For example, one site might be approaching renewal while another has two years remaining on its contract.

Without a centralised approach, businesses can end up managing contracts reactively rather than strategically.

Multi-site energy management can help bring this information together, providing a clearer picture of contracts, consumption and renewal dates across your business.

This can make it easier to plan procurement decisions and identify opportunities across your entire property portfolio.

Fixed or flexible: which business energy contract is right?

One of the key decisions businesses may need to consider during renewal is whether a fixed or flexible contract is appropriate.

Fixed energy contracts

A fixed contract can provide greater price certainty because the agreed energy rate is fixed for a specified period, subject to the terms of the contract.

This can make budgeting easier and provide businesses with greater certainty around future energy costs.

However, fixing your price also means you may not benefit from future falls in relevant market prices.

Flexible energy contracts

Flexible procurement can provide greater flexibility around purchasing energy and may allow businesses to take advantage of market opportunities.

However, it can also involve greater exposure to market movements and may require more active management.

Neither approach is automatically right for every business.

The appropriate procurement strategy depends on factors such as your energy consumption, financial position, risk appetite, business requirements and market conditions.

A business energy contract renewal checklist

Before agreeing to your next business energy contract, it is worth working through a simple checklist.

☐ Do you know exactly when your current contract ends?

☐ Have you reviewed your existing contract and rates?

☐ Have you checked your standing charges?

☐ Have you reviewed your recent energy consumption?

☐ Has your business changed since your current contract began?

☐ Have you checked your recent energy bills for errors?

☐ Have you considered your future energy requirements?

☐ Have you reviewed the supplier's renewal offer?

☐ Have you considered alternative contracts and suppliers?

☐ Have you considered fixed versus flexible procurement?

☐ Have you considered current wholesale market conditions?

☐ Have you allowed enough time to make an informed decision?

If you can't answer these questions confidently, it may be time to review your current energy arrangements.

Common mistakes businesses make when renewing energy contracts

A business energy contract renewal doesn't have to be complicated, but there are several common mistakes worth avoiding.

Leaving it until the last minute

Waiting until your contract is about to expire can put unnecessary pressure on the decision-making process.

Automatically accepting the renewal offer

Your existing supplier's offer may be convenient, but convenience doesn't necessarily mean it is the right option for your business.

Focusing only on the unit rate

The unit rate is important, but it isn't the only component of your overall energy cost.

Ignoring consumption changes

Using old consumption information without considering how your business has changed could result in a procurement strategy that doesn't reflect your future requirements.

Failing to check existing bills

Renewal is a good opportunity to identify billing discrepancies before moving forward with your next contract.

Trying to predict the energy market

No one can accurately predict every movement in wholesale energy prices. A structured procurement strategy can be more useful than trying to identify the perfect day to fix your price.

Forgetting about the next renewal

Once your new contract has been arranged, record the important dates and start planning for the next review well in advance.
