Energy brokers do one thing exceptionally well: they negotiate better rates than businesses could get on their own. Market access, supplier relationships, volume leverage. That part of the model works.
But there’s a gap in the service that most brokers don’t fill. Once the contract is signed, nobody checks whether the supplier is actually billing the agreed rates. And that’s where a surprising amount of money gets lost.
The gap between the contract and the bill
A broker negotiates a unit rate of, say, 24.5p/kWh. The contract gets signed. Everyone moves on. Six months later, the supplier is billing 25.1p/kWh. Nobody notices because nobody is comparing the bill to the contract line by line.
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. These aren’t edge cases. They’re routine.
For a broker managing 200 clients, that’s roughly 40 clients being overcharged at any given time. If the broker isn’t catching those errors, the client is paying money they shouldn’t be.
Why this matters for brokers
There are three reasons brokers should care about bill accuracy, even though it’s technically the supplier’s responsibility to bill correctly.
Retention. A broker who catches a billing error is demonstrably adding value between renewals. That’s hard for a competitor to undercut. The broker who checks the bills keeps the account.
Revenue. Bill validation can be offered as a service — either bundled into the broker’s offering or as a paid add-on. It creates recurring value that doesn’t depend on the renewal cycle.
Compliance. With TPI regulation coming from Ofgem, brokers will need to demonstrate they’re acting in their clients’ interests throughout the contract, not just at the point of sale. Systematic bill validation is one of the clearest ways to do that.
What Edge does
Edge is bill validation software built specifically for energy brokers. It’s not a brokerage. It’s a tool that helps brokers do their job better.
Here’s how it works:
- Upload a bill — by file upload or API integration with your existing CRM.
- Automatic validation — Edge’s AI extracts every charge and compares it against the contract on file. Unit rate, standing charge, VAT, CCL, consumption figures, billing periods.
- Errors get flagged — with the specific overcharge in pounds and a drafted supplier query ready to send.
- Clean bills pass through — with a green tick, so your team only spends time on the ones that need attention.
The whole process takes about 30 seconds per bill.
How this fits into a broker’s workflow
Edge isn’t trying to replace anything a broker already does. It slots in alongside existing systems.
If you use a CRM like UtilityClick, Salesforce, or HubSpot, Edge works alongside it. If you track contracts in spreadsheets, that works too. The validation layer sits on top of whatever process you already have.
The key shift is that bill checking goes from something that happens occasionally (or not at all) to something that happens automatically on every bill for every client.
What brokers typically find
When brokers start validating bills systematically, they usually discover errors they didn’t know existed. The most common:
- Unit rates that don’t match the contract — the single most frequent and most expensive error.
- VAT charged at 20% instead of 5% — many small businesses qualify for the reduced rate but never get it applied.
- Standing charge discrepancies — small daily differences that compound across a year.
- Estimated reads running uncorrected — consumption estimates that drift further from reality with each billing cycle.
