UK Business Energy Claims for Supermarkets and Grocers: A Comprehensive Guide
Supermarkets and independent grocers operate some of the most energy‑intensive retail premises in the UK, driven above all by refrigeration and freezer cabinets that run twenty‑four hours a day, seven days a week, alongside bright store‑wide lighting, in‑store bakeries, and climate control across large floor areas. This scale of consumption made grocery retail a prime target for brokers seeking to extract undisclosed commission from long‑term supply contracts. The legal position has been reshaped by the Court of Appeal's judgment in Expert Tooling and Automation Ltd v Engie Power Ltd [2025] EWCA Civ 292, upheld by the Supreme Court's consent judgment of 9 January 2026, and grounded in the fiduciary duty principles established in Wood v Commercial First Ltd [2021] EWCA Civ 471. This guide sets out how brokers targeted supermarkets and grocers, the legal framework now available, and how to pursue recovery of hidden overcharges.
The Hidden Cost of Energy Broker Commissions in the Supermarket and Grocery Sector
Store managers and retail finance teams engaging a broker to arrange energy supply are told they are securing a competitive rate for a large, complex site. In practice, the supplier offers the broker a discounted wholesale price, to which an uplift is added before the final rate reaches the store. Given that refrigeration alone can account for a substantial share of a grocery store's total electricity use, running continuously regardless of trading hours, even a small per‑unit markup compounds into a very large sum across a multi‑year contract, particularly for chains operating dozens of branches under near‑identical terms.
How Third‑Party Intermediaries Target Supermarkets and Grocers
Brokers are drawn to grocery retail because each store represents a substantial, stable energy account, and a chain of stores multiplies that value many times over. The broker's pitch typically emphasises the complexity of multi‑meter, high‑consumption sites and its own specialist ability to navigate that complexity, while never volunteering the size of its own commission. Contract renewals are frequently timed around seasonal peaks such as the Christmas trading period, when store management has limited capacity to interrogate contract detail.
The Legal and Regulatory Red Flags Set by the Expert Tooling Case
Expert Tooling established that a broker must disclose the exact commission amount, method of calculation, and cumulative cost impact before a contract is signed; mere awareness of a possible fee is not informed consent. The Supreme Court's consent judgment of 9 January 2026, following Hopcraft v Close Brothers Ltd [2025] UKSC 33, abolished the distinction between half‑secret and fully‑secret commissions, meaning any supermarket or grocery contract lacking a detailed written breakdown of broker earnings can now be challenged.
The Upcoming Ofgem Regulatory Shifts and Why You Should Act Now
Since October 2024, Ofgem has required commission disclosure in non‑domestic contracts, with full statutory regulation of brokers expected by 2027 and 2028 following the government's 23 October 2025 announcement. Grocery retailers that signed contracts between 2020 and 2023 should act within the six‑year window under the Limitation Act 1980, particularly while broker correspondence and billing records remain available across every store.
Addressing the Common Objection That the Broker Saved the Business Money
Brokers frequently point to savings against an out‑of‑contract rate, but that rate is deliberately punitive, not a genuine market benchmark. As Expert Tooling confirms, the legality of the arrangement depends on full disclosure of the broker's own earnings, regardless of whether it improved on a punitive default tariff.
The Practical Implications for Supermarkets and Grocers and How to Begin the Claim Process
A claims review begins with gathering signed energy contracts, broker sales correspondence, Letters of Authority, and recent bills for every store in the estate. Check your eligibility here to begin an independent assessment of your supermarket or grocery business's historic energy agreements.

Frequently Asked Questions About Supermarket and Grocery Energy Claims
Is there a time limit on energy claims for supermarkets and grocers?
Yes, the Limitation Act 1980 generally imposes a six‑year time limit, though the Section 32 concealment exception can delay the start of that period. Many contracts between 2020 and 2026 are likely actionable, but a specific legal assessment for each store is essential.
Do I need a lawyer to make an energy claim for my supermarket or grocery store?
An initial assessment can be done with AI, but formal claims against large brokers and suppliers are legally complex. A solicitor familiar with the Expert Tooling ruling significantly improves the chances of a maximum settlement.
How does the Expert Tooling case affect my supermarket or grocery business?
The Expert Tooling case, finalised by the Supreme Court in January 2026, abolished the distinction between half‑secret and fully‑secret commissions, giving immediate grounds to review historic contracts where commission was not explicitly disclosed.
