If your business energy bill has jumped in the last renewal cycle, you’re not alone — and you’re not stuck with whatever your supplier quotes you. A business energy broker exists to put your gas and electricity contract in front of the whole market instead of just one supplier, so you’re negotiating from a position of competition rather than accepting a single renewal offer.
This guide covers exactly what a business energy broker does, how they get paid, whether they’re actually cheaper than going direct, and what to check before you sign with one.
What Is a Business Energy Broker?
A business energy broker buys energy on your behalf instead of you dealing with suppliers one at a time. A whole-of-market broker tenders your gas and electricity usage across a panel of suppliers, negotiates unit rates and standing charges, and manages the contract from quote through to renewal.
The key distinction is whole-of-market vs. tied. A whole-of-market broker works for you and recommends whichever supplier offers the best deal. A tied broker (or one working off a short supplier panel) is often steering you toward whoever pays the biggest commission. Always ask which one you’re talking to.
What Does a Business Energy Broker Actually Do?
A good broker’s job goes well beyond finding a lower unit rate. In practice, it covers:
- Tendering your usage profile across a panel of suppliers rather than a single quote
- Negotiating contract terms, not just headline price — length, exit clauses, pass-through costs
- Validating invoices for billing errors, which are more common than most businesses realise
- Tracking your renewal window so you don’t roll onto expensive out-of-contract rates
- Advising on market timing — when wholesale prices dip, that’s when to lock in a fixed term
- Managing multi-site contracts with consolidated billing and reporting for businesses with more than one location
For larger energy users, this can extend into flexible purchasing, half-hourly data analysis, and carbon reporting support.
How Do Energy Brokers Get Paid?
There are two common models:
- Commission built into the unit rate the supplier quotes you — you never see a separate invoice from the broker, but the rate includes their cut.
- A fixed fee, with the broker passing through a lower supplier rate in exchange.
Neither model is inherently wrong, but the amount should be disclosed to you in writing before you sign anything. A broker that won’t tell you how it’s paid is a red flag. A broker with no preferred-supplier deals is what allows genuinely whole-of-market tendering, rather than a shortlist that quietly favours whoever pays the most commission.
Is It Cheaper to Use a Broker or Go Direct to a Supplier?
Going direct gets you one supplier’s price, on one day, with no competitive pressure. A broker puts that same supplier in competition with dozens of others for your contract — and that competition is where the saving actually comes from.
Typical savings from switching via a broker run 15–30% against out-of-contract or auto-renewal rates, which is what most businesses end up paying if they let a contract lapse without shopping around. On top of the headline rate, brokers also catch billing errors and mistimed renewals — costs that are easy to miss but add up over a contract term.
How Much Can a Business Actually Save?
The real number depends on three things: your current contract, your usage, and where the wholesale market sits when you tender. As a rough benchmark, 15–30% against an out-of-contract or auto-renewal rate is typical, and multi-site businesses often save more once billing consolidation and error-catching are factored in.
For a concrete example: one manufacturing client saw a 20% reduction on a roughly £37,000 annual gas spend by timing a fixed-price switch to a market dip — a saving north of £22,000 over three years. A multi-site bakery group cut annual energy costs from around £150,000 to £82,000 across all its locations. These aren’t universal outcomes, but they show the range of what whole-of-market tendering can achieve compared with a single-supplier renewal.
How to Choose the Right Business Energy Broker
Before signing with any broker, ask three questions:
- Are they whole-of-market, or tied to a small supplier panel?
- Is their commission disclosed in writing, before you commit?
- Can they show proof of results with named clients, not just generic testimonials?
Independent accreditations are worth checking too. Look for certifications like B Corp status, ISO 9001, and membership of a formal redress scheme — these signal a broker that’s been externally audited rather than one making unverifiable claims about itself.
Are Energy Brokers Regulated in the UK?
Not in the same way suppliers are. Suppliers hold an Ofgem licence; brokers, as third-party intermediaries, currently do not. Ofgem does require brokers serving microbusinesses to belong to a redress scheme such as the Energy Ombudsman, and reputable brokers voluntarily commit to clear commission disclosure on top of that minimum requirement. Because broker regulation is lighter-touch than supplier regulation, independent accreditation and a redress scheme membership are the practical checks worth making.
Does a Business Energy Broker Only Handle Gas and Electricity?
The core service is business gas and electricity, but a full-service brokerage typically extends further — business water, solar and battery storage, carbon reporting and compliance support, and ongoing invoice validation after the contract is signed. Consolidating all of this under a single account manager is usually where multi-site businesses save the most on admin time as well as money.
Frequently Asked Questions
Is using a business energy broker free? Usually, yes — the broker’s fee is typically built into the supplier’s unit rate rather than charged to you separately, though some operate on a fixed-fee basis instead. Ask upfront which model applies.
Will switching broker or supplier cause my business to lose power or gas supply? No. Switching is a change of billing and contract, not a physical disconnection — your supply continues without interruption during a switch.
How far in advance should I start the renewal process? Most brokers recommend starting 3–6 months before your current contract ends, since wholesale prices fluctuate and locking in during a dip requires lead time to tender and switch before the old contract expires.
Can a broker help if I have multiple business sites? Yes — this is often where brokers add the most value, consolidating billing across sites into a single point of contact and a single renewal calendar instead of tracking multiple contracts separately.
The Bottom Line
A business energy broker’s value comes from competition: putting your usage profile in front of a wide supplier panel instead of accepting a single renewal quote. The savings are real when the broker is whole-of-market, discloses how it’s paid, and can show results with named clients — and the risk is mainly in picking a broker that’s tied to a narrow panel while presenting itself as independent. Ask the three questions above before you sign, and you’ll avoid most of the pitfalls.
