The energy market in 2026 is complex and volatile. Whether it’s planned non-commodity fees or unplanned spikes due to geopolitical issues, businesses are being hit with eye-watering energy bills.
And to make energy procurement even more confusing, there’s a host of energy firms out there vying for the eyes of every UK business. But choosing the right energy broker in 2026 is becoming increasingly essential for running an efficient business.
We are here to take you through some of the common pitfalls businesses face when they discover they have signed with the wrong energy broker, so you don’t make the same mistakes.
Here at Renew & Sustain, we are more than a call-centre reseller with a quick commission at the front of their minds. We act as a supportive energy procurement partner for all of our clients. This means swapping some of the energy broker red flags with a host of green ones, including ongoing support, gathering data to understand each business’s unique energy usage and finding a contract with long-term interests in mind.
What Questions to Ask a Potential Energy Broker for Business
Below, we highlight a few key questions you should ask any potential energy broker and explain why each is important to your business. Let’s make sure your business chooses the right energy broker in 2026.
1. Transparency of Fees
The question to ask: Do you clearly disclose your commission structure?
Many brokers embed their commission into the unit rate, making it invisible. While this isn’t illegal or inherently wrong, the lack of transparency poses a problem for businesses seeking their best long-term energy options.
Not having full knowledge of how your broker is being paid means your business can’t assess if their recommendations are the best option. Transparent brokers openly disclose their costs and may give businesses the option to adjust them.
2. Ongoing Support
The question to ask: Do you provide ongoing support after my business has signed the contract?
Some energy brokers will disappear once the contract is signed, and ongoing support for their clients is not part of their offering.
With Renew & Sustain, energy procurement doesn’t end with your signature. Ongoing services such as bill validation, consumption monitoring via smart submetering services, and energy-use anomaly detection can save you thousands of pounds over the contract term.
3. Energy Bill Breakdowns
The question to ask: Can you explain my non-commodity costs and how much they contribute towards my business’s energy bill?
Some energy brokers purely focus on your unit rate, which is not the entire picture. Elements such as non-commodity charges (DUoS, TNUoS, BSUoS, etc.) can make up around 60% of your total energy cost.
If an energy broker doesn’t explain these, you’re being kept in the dark about how your business’s energy costs are composed.
4. Eye-Opening Audits
The question to ask: Have you reviewed whether my agreed capacity is set correctly?
Incorrect kVA capacity can lead to unnecessary fixed charges or expensive excess capacity penalties. A proper business energy audit ensures you’re not overpaying before you review your energy usage at new rates.

What Does kVA Capacity Mean?
Your kVA capacity is the amount of electricity your site is allowed to use at any one time. It’s like a limit agreed with your energy supplier.
- If it is set too high, you pay for more capacity than you need
- On the other hand, if it is set too low, you will get charged a penalty.
Energy Broker Green Flag for kVA Capacity
A good energy broker for business would not jump straight to pricing contracts. They should:
- Look at your real usage data
- Compare it to your current capacity setting
- Identify if you’re overpaying or at risk of penalties
- Recommend adjusting it before renewing or switching contracts.
5. Supplier Relationships
The question to ask: Do you cover the whole market, or just a preferred panel?
Some brokers only work with two or three energy suppliers, the ones with which they have strong commercial relationships. This can limit your energy or pricing options and may not offer the best outcome for your business.

6. The Best Type of Contract
The question to ask: Why is this contract structure right for my business?
Different types of energy contracts for business come with different degrees of risk. A good broker aligns the structure with the willingness or ability of your business to absorb risk, not just what’s easiest to sell.
Types of energy contracts for business include:
- A fixed contract locks in a price for the full term, giving you predictable bills. It’s great if you value certainty, but you won’t benefit if market prices drop.
- A flexible contract lets you buy energy in stages, taking advantage of market dips, but it requires more active management and comes with some risk.
- A pass-through contract combines fixed and variable elements, which can lower costs but makes bills less predictable.

Energy procurement red flag: Pushing the “cheapest” deal just to get a sale.
The key to avoiding this red flag is to ensure the contract type matches your business. Some brokers will just push whatever contract is easiest to sell, often a standard fixed deal, without considering your business needs. A good broker will take the time to understand your business, explain the pros and cons of each option, and recommend a contract that aligns with your comfort level for risk.
7. Supplier Reputation
The question to ask yourself: How do I check that suppliers are stable, reliable and trusted?
The key here is to look beyond just price. Do some research on the broker, especially if the price seems a little too good to be true, and build a picture of their reputation. Do they have good reviews or any client case studies? Heading into a contract with a less-trusted supplier could spell further costs down the line, so it’s well worth taking the time to find an energy broker you feel comfortable partnering with, especially if your business is taking a longer-term view.
Without looking around, you could be stuck with an energy supplier that offers a low rate but is financially unstable, or with one that has poor customer service, leaving you in the lurch.
Things to check:
- Financial stability: Will the supplier remain in business for the full contract term?
- Service quality: Are they responsive when problems arise?
- Track record: Do they have a history of smooth operations and satisfied customers?
By looking into these factors, you’re reducing unnecessary risks. Stability and reliability might not be as immediately tempting as a low price, but they protect your business from unexpected costs and disruption.
8. Data and Consumption Analysis
The question to ask: Have you analysed my historical consumption in detail?
In short, accurate procurement decisions need a good understanding of your usage patterns, not just headline annual consumption. Essentially, poor data means poor contracts, which can cost your business unnecessary expense.
Energy procurement red flag: Uninformed contracts
What some energy brokers don’t do is look further into how and when your business uses its energy. They might only consider your total yearly consumption, which can lead to uninformed decisions that don’t tell the full story of your usage.
At Renew & Sustain, we will look into factors such as peak usage times during the day, seasonal trends, and any unusual spikes or drops in demand to fully understand your business’s energy usage and get you the best-fitting deal.
This deeper analysis matters because energy prices and contract structures can vary depending on your usage pattern. For example, a business that uses most of its energy during peak hours may need a different approach compared to one that operates overnight or on weekends. Without this insight, you could be placed on a contract that doesn’t suit how your business actually runs.
Proper data analysis also helps identify opportunities to reduce waste, improve efficiency, and avoid unnecessary costs, which is what our energy consultation experts do best at Renew & Sustain.
9. Checking for Billing Accuracy
What to ask: Will you check my invoices for errors?
Billing errors are more common than most businesses realise. Without validation, you may be overpaying without knowing it.
10. Service Levels and Support
The questions to ask: What are your response times and service commitments?
When issues arise, customer service and support matter. Larger brokers might operate a lower level of service with slower response times. This can delay resolutions, or a lack of support can affect your business.
At Renew & Sustain, every one of our partners gets a dedicated account manager as a primary contact, as well as access to our entire team’s energy consultancy expertise. We also offer 24/7 support, so you can always raise a question and get the support you need.
Renew & Sustain’s energy procurement contracts take your business’s unique needs into account, and our ongoing support is available whenever you need it.
Energy Procurement in 2026: Common Myths
There are a few common myths surrounding energy procurement for business. Let’s highlight a few so that you can feel confident in your energy procurement decisions.
Myth 1: All brokers are the same
Some operate as high-volume sales operations focused on commission. Others, such as Renew & Sustain, act more like strategic partners, prioritising long-term value and operational efficiency.
Myth 2: The cheapest rate is always the best deal. It rarely is. The lowest rate can mean the wrong contract structure, hidden risks, or working with unstable suppliers. True value comes from the right strategy, not just the lowest number.
Myth 3: Bigger brokers are safer. Not necessarily. Larger firms often prioritise volume and targets over service quality. This can result in slower response times and less personalised support.
