When it comes to energy bill validation, brokers have two options: do it yourself with software, or outsource it to a bureau. Both catch errors. Both recover money. But they work very differently, cost very differently, and suit very different types of brokerage.
What's a bureau service?
A bureau service is an outsourced team that handles bill validation on your behalf. Companies like Inspired PLC, LASER Energy, and EIC offer this. You send them your client bills (or give them access to supplier portals), and their team checks every invoice, flags errors, and raises queries with suppliers.
It's a managed service. You hand over the bills, they do the work, you get reports back.
The big players:
- Inspired PLC — the largest in the UK, processing 2.5 million bills per year. They recovered £37 million in overcharges last year alone.
- LASER Energy — a public sector buying organisation that also offers bureau services to commercial clients.
- EIC — Energy Intelligence Centre, offering validation alongside broader energy management services.
What's bill validation software?
Software like Edge gives your team the tools to validate bills in-house. Bills flow into the system, get checked automatically against the contract on file, and come back green (clean) or flagged (error found). Your team reviews the flags, confirms the errors, and sends the supplier queries.
The validation is automated. The decision-making stays with you.
How they compare
Cost
Bureau services typically charge per bill or take a percentage of recovered overcharges. Per-bill fees range from £2-£10 depending on the provider, volume, and service level. Percentage-of-recovery models take 20-40% of whatever they claw back.
On a portfolio of 500 bills per quarter, a bureau service at £5 per bill costs £10,000 per year. A percentage model on £50,000 in recovered overcharges takes £10,000-£20,000.
Software subscriptions are generally lower. Edge, for example, is priced per client per month with no per-bill charges and no recovery fees. The total cost depends on portfolio size, but it's typically a fraction of bureau pricing.
Speed
Bureau services operate on their own timeline. You send bills in, they process them in batches, and you get results days or weeks later. The turnaround depends on their workload and your priority level as a client.
Software validates in near-real-time. Upload a bill, get results in seconds. If you're integrated via API, bills get validated as they arrive without any manual step at all.
For brokers who need to respond quickly to client queries about specific bills, the speed difference matters.
Control
This is the biggest practical difference.
With a bureau, the validation happens in someone else's system, using their methodology, on their schedule. You get the output but you don't control the process. If you disagree with how an error was classified, or want to prioritise certain checks, you're making requests rather than changes.
With software, you control the workflow. You set the contract terms, you configure the checks, you decide which flags to pursue and which to dismiss. Your team builds expertise in validation rather than outsourcing it.
For brokerages that want bill validation to be a core competency — something they market to clients and use for retention — in-house control matters.
Scalability
Bureau services scale by adding headcount. That works up to a point, but it means costs increase roughly linearly with volume. Processing twice as many bills costs roughly twice as much.
Software scales differently. The marginal cost of validating one more bill is close to zero. Whether you're processing 100 bills or 10,000, the software cost stays relatively flat. The only variable cost is your team's time reviewing flags.
Client relationship
With a bureau, the validation sits between you and your client. The bureau finds the error, but you present it. Your client may or may not know there's a third party involved.
With software, validation is your service. Your team catches the error, your system flags it, your client sees you delivering the value. There's no middleman in the relationship.
When a bureau makes sense
Bureau services work well when:
- You don't have the internal capacity to run validation, even with software
- Your portfolio is very large and you need a managed service while you build internal capability
- You want someone else to handle the supplier dispute process end to end
- Bill validation isn't central to your value proposition — it's a nice-to-have, not a differentiator
When software makes sense
Software works well when:
- You want bill validation to be part of your core service offering
- You want to control the process, the data, and the client relationship
- You're cost-conscious and want to keep more of the recovered value
- You need real-time or near-real-time validation rather than batch processing
- You're building a tech-forward brokerage and want validation integrated into your platform
The hybrid approach
Some brokerages use both. Software handles the routine validation — checking every bill automatically and flagging errors. A bureau handles the complex disputes — historical claims, multi-year reconciliations, or supplier negotiations that require specialist knowledge.
This gives you the speed and cost efficiency of software for day-to-day validation, with the deep expertise of a bureau for the edge cases.
Making the choice
The question isn't which approach is better in the abstract. It's which one fits your brokerage.
If you want to see what software-based validation looks like in practice, how it works walks through the Edge process from bill upload to supplier query. You can also check our pricing to see how it compares to bureau fees, or try Edge free and run your first batch of bills through to see what it catches.
