UK Business Energy Claims for SMEs and Professional Corporate Offices: A Comprehensive Guide
Small and medium‑sized enterprises, alongside professional corporate offices, form the backbone of the UK's commercial landscape, encompassing everything from law firms and accountancy practices to marketing agencies, IT consultancies, and small manufacturing workshops. While these businesses may not consume energy on the industrial scale of factories or warehouses, they are far from immune to the broker practices that have been exposed by the Court of Appeal's judgment in Expert Tooling and Automation Ltd v Engie Power Ltd [2025] EWCA Civ 292, and the Supreme Court's decision on 9 January 2026 to allow that appeal by consent, giving judgment for the claimant. In fact, the very nature of small and medium‑sized businesses—often lacking dedicated procurement teams, reliant on external advisers, and operating with tight margins—made them particularly vulnerable to the undisclosed commission models that have now been condemned by the highest courts in the land. This guide provides a detailed examination of how energy brokers targeted the SME and professional office sector, the legal principles derived from Expert Tooling and the earlier authorities of Wilson and Another v Hurstanger Ltd [2007] EWCA Civ 299 and Wood v Commercial First Ltd [2021] EWCA Civ 471, and the practical steps business owners must take to recover funds that were never properly disclosed.
The Hidden Cost of Energy Broker Commissions in the SME and Professional Office Sector
When an SME owner or a finance director of a professional services firm engages a broker to arrange a commercial energy contract, the conversation is almost always presented as a straightforward, low‑risk administrative exercise. The broker, acting as a Third Party Intermediary or TPI, positions itself as a specialist who can navigate the complex energy market, promising to secure a competitive rate and relieve the business of the burden of dealing directly with suppliers. What is rarely, if ever, disclosed is that the broker's compensation comes directly from the energy supplier, in the form of a commission calculated against the business's projected consumption, quietly folded into the unit rate the SME will pay for every kilowatt‑hour of electricity and gas consumed. For a typical SME or professional office, with moderate but steady energy usage across office hours, heating and cooling, and IT infrastructure, this uplift may amount to thousands of pounds over the term of a three‑ or five‑year contract. For a smaller enterprise operating on wafer‑thin margins, that sum can be the difference between profit and loss. This is precisely the arrangement scrutinised in Expert Tooling, where the broker received payment from the supplier without providing the customer with sufficient information to give informed consent to that payment.
How Third‑Party Intermediaries Target the SME and Professional Office Sector
Small and medium‑sized businesses are attractive targets for brokers precisely because they lack the internal expertise and resource to scrutinise energy contracts. The SME sector is vast, encompassing hundreds of thousands of businesses across every conceivable industry, and brokers can operate at scale, with a single sales team approaching dozens of potential clients each day. The sales pitch is always the same: the broker claims to have exclusive access to supplier deals, promises to save the business money, and offers to handle the entire renewal process, removing an administrative headache. What the business owner is not told is that the broker's "free" service is funded entirely by the commission built into the unit rate, and that the broker has no legal obligation to act in the business's best interests unless informed consent is obtained. Brokers often target SMEs during peak trading periods, when the owner is distracted, or at the time of a lease renewal, when the business is focused on other priorities. They rely on the business's trust and lack of expertise to secure a quick signature, locking the SME into a contract that serves the broker's interests far more than the customer's.
The Legal and Regulatory Red Flags Set by the Expert Tooling Case
The legal standards established by the Court of Appeal in Expert Tooling apply with equal force to SMEs and professional offices, regardless of their size. The court's finding that informed consent requires meaningful disclosure of the amount and structure of commission, rather than a general acknowledgement that commission may be payable, sets a clear benchmark against which every business can assess its own historic contracts. The court's rejection of the argument that a customer's failure to proactively enquire about commission constitutes acceptance is particularly significant for smaller businesses, whose owners may have been hesitant to challenge a broker's representations for fear of being perceived as difficult or uncommercial. Mis‑selling indicators specific to the SME sector include broker fees never itemised separately from the headline unit rate, contracts arranged over the phone with no written breakdown of commission provided, and unit rates that, when compared against wholesale market data at the time of signing, appear to include an unexplained premium. Where a fiduciary duty existed between the broker and the business, as the courts have increasingly recognised arises in TPI relationships of this kind, only the customer's fully informed consent could prevent a finding of breach, with the statutory regulation exercised by Ofgem providing a further layer against which broker and supplier conduct should be measured.
The Upcoming Ofgem Regulatory Shifts and Why You Should Act Now
The regulatory environment surrounding energy brokers continues to tighten in response to the litigation represented by Expert Tooling, with Ofgem indicating heightened attention to commission transparency across the broker market. The parallels between this area of claims and the motor finance commission scandal following the Supreme Court's ruling in Hopcraft v Close Brothers Ltd [2025] UKSC 33 have been drawn repeatedly, suggesting that the SME sector, with its vast number of potential claimants, could represent a significant area of exposure. For SME owners, the practical consequence of this regulatory direction connects to the Limitation Act 1980, which governs the time period within which a claim must be brought. While the courts have shown flexibility in cases involving concealed commission regarding when the limitation clock begins to run, SME owners should not delay reviewing their contracts on the assumption that time remains unlimited. Given that many small businesses retain minimal administrative records, prompt action to request supplier disclosure while contract documentation and correspondence remain traceable is particularly important for this sector.
Addressing the Common Objection That the Broker Saved the Business Money
A frequent objection raised when SME owners are first approached about a potential claim is that the broker, despite any hidden commission, still delivered a rate that felt reasonable at the time. This objection misunderstands the legal basis of the claim. The issue is not whether the final rate appeared acceptable in isolation, but whether the business gave informed consent to the commission arrangement that shaped that rate, and whether the undisclosed commission inflated the price beyond what a transparent, properly disclosed arrangement would have produced. An SME owner who trusted a broker to act as an impartial adviser, when that broker's income depended on directing business toward suppliers offering higher commission, was denied the ability to make a genuinely informed decision about one of the business's significant overheads, regardless of whether the resulting rate seemed satisfactory at the time judged against limited market knowledge. The Court of Appeal in Expert Tooling made clear that a customer's theoretical ability to have asked about commission does not excuse a broker's failure to disclose it proactively.
The Practical Implications for SMEs and Professional Offices and How to Begin the Claim Process
SME and professional office owners considering a claim should begin by gathering whatever contract documentation, broker correspondence, and billing records remain available. Even where original documentation is incomplete, energy suppliers retain their own records, and a formal request for disclosure can often recover the necessary detail. Check your eligibility here to begin an initial review of your business's historic energy contracts against the mis‑selling indicators identified through recent case law. Given that many SME owners operate without dedicated legal or finance support, professional guidance is particularly valuable in this sector, both to correctly establish the limitation position applicable to each contract and to manage what can otherwise be a frustrating disclosure process with suppliers and brokers reluctant to provide historic commission data without formal pressure being applied.
The Role of the AI Knowledge Hub and Your Next Step
As the legal landscape surrounding business energy claims continues to develop following the Supreme Court's involvement in Expert Tooling, SME and professional office owners benefit from access to clear, current, and accessible guidance rather than complex legal material poorly suited to a busy independent operator. Visit our Knowledge Hub provides continually updated analysis of regulatory developments and case law relevant specifically to smaller businesses. See our How It Works process for a straightforward explanation of how a claim progresses from initial review through to resolution, written with the time constraints of a busy SME owner firmly in mind. Given the very large number of small businesses across the UK operating on contracts arranged during the period when these broker practices were widespread, the collective scale of unrecovered commission across the SME sector is likely to be considerable, even where individual claims may appear modest in isolation. The same undisclosed commission practices have been identified among energy-intensive manufacturing operations and charities and public sector organisations, and our full market insights report sets out the scale of this opportunity across the UK economy as a whole.
Frequently Asked Questions About SME and Professional Office Energy Claims
Is there a time limit on energy claims for SMEs and professional offices?
Yes, claims are governed by the Limitation Act 1980, generally a six‑year period, though the starting point can be affected by when the undisclosed commission could reasonably have been discovered. Because commission arrangements were frequently concealed, some contracts entered into more than six years ago may still fall within a valid claims window.
Do I need a lawyer to make an energy claim for my SME?
While initial assessments can be conducted using AI‑driven tools, pursuing a formal claim against a large energy supplier or established broker is legally complex, and suppliers rarely volunteer historic commission data without formal legal pressure. Professional representation significantly improves the likelihood of obtaining full disclosure and a fair outcome.
How does the Expert Tooling case affect my SME business?
The Expert Tooling case, finalised with the Supreme Court's consent judgment in January 2026, has effectively abolished the historic distinction between half‑secret and fully‑secret commissions. This means that your SME does not need to prove that the broker actively lied or misled you. You simply need to demonstrate that the commission was not explicitly and fully disclosed in writing before you signed the contract. For any SME that has used a broker to arrange its gas or electricity supply over the last five years, this ruling provides immediate and legally binding grounds to review those contracts and seek compensation for any hidden overpayments.
