Energy brokers have a reputation problem. And honestly, some of them have earned it. Opaque fees, hidden commissions, and contracts that benefit the broker more than the client — it's no wonder business owners are sceptical.
But a good broker can genuinely save you money. The key is understanding how the model works and what to look for.
How brokers get paid
Most energy brokers don't charge you directly. Instead, they receive a commission from the energy supplier, which is built into your unit rate. You pay the supplier, and the supplier pays the broker a small amount per kilowatt-hour (kWh) of energy you use.
This means the broker's fee is embedded in the price you see. It's not a separate invoice or a hidden charge — but it's also not always transparent, and that's where problems start.
Typical commission ranges:
- Electricity: 0.1p to 0.8p per kWh
- Gas: 0.1p to 0.5p per kWh
The difference between 0.1p and 0.8p might sound small, but on a business using 100,000 kWh of electricity a year, that's the difference between paying your broker £100 and £800. Over a multi-year contract, it adds up fast.
Where the savings come from
A good broker saves you money in three main ways:
1. Market access
Energy suppliers don't all offer the same rates. Prices vary based on your consumption profile, your location, your meter type, and the supplier's current position in the market. A broker who compares the whole market — not just a preferred panel — will find rates you'd never see if you went direct.
In fact, many suppliers only offer their best rates through brokers. Going direct doesn't guarantee a better price, and often means you're only seeing one option.
2. Negotiation
Brokers negotiate rates every day. They know which suppliers are competitive for your type of business, which ones are running promotions, and which terms are worth pushing back on. A business owner negotiating once every two or three years simply can't match that.
3. Time
Searching the energy market properly takes time. Gathering quotes, comparing terms, understanding the fine print — it's hours of work. A broker does this for a living. Your time is better spent running your business.
What to look for in a broker
Not all brokers are created equal. Here's what separates the good ones from the rest:
Transparency. You should be able to ask your broker exactly how much they're earning from your contract, in pounds and pence. If they won't tell you, walk away.
Whole-of-market comparison. Some brokers only work with a handful of suppliers. This means they're not searching the full market — they're presenting the best option from a limited pool. Ask whether they compare every available supplier.
No lock-in. Your broker should earn your business through service, not contractual obligation. If you're locked into a multi-year agreement with your broker regardless of performance, that's a red flag.
Proactive management. A good broker doesn't just find you a deal and disappear. They should be tracking your contract end dates, monitoring the market, and reaching out before your renewal is due.
Where brokers fall short: after the switch
Even the best broker typically disappears between renewals. They find you a great rate, sign the contract, and you don't hear from them until the next renewal window. But what happens to your bills in the meantime?
Industry data shows that 1 in 5 energy bills contain errors. Wrong unit rates, incorrect VAT, standing charge mismatches, estimated reads that never get corrected. A broker negotiates the contract terms, but nobody checks whether the supplier is actually billing you according to those terms.
That's where bill validation comes in. Once you've switched, make sure your new bills are correct. Edge validates every charge against the contract automatically, catching errors that would otherwise go unnoticed until your next renewal.
The bottom line
A bad broker costs you money. A good broker saves you more than they cost. The difference comes down to transparency, market access, and whether they're genuinely working in your interest.
But even with a great broker, your bills still need checking. The best rate in the world doesn't help if the supplier isn't billing it correctly.
