Key Takeaways

• The CMA has issued an open letter reminding domestic heating oil suppliers that consumer contract terms must be fair and transparent, with particular focus on terms that remove or reduce supplier liability.
• The letter follows a CMA intervention over order cancellations during a price and demand surge tied to the Middle East conflict, which resulted in voluntary compensation for hundreds of customers.
• Compliance teams in any consumer-facing sector should treat it as a signal of enforcement priorities for contract terms during market volatility.

Deep Dive

The CMA has issued an open letter reminding domestic heating oil suppliers that consumer contract terms must be fair and transparent, with particular focus on terms that remove or reduce supplier liability. The letter follows a CMA intervention over order cancellations during a price and demand surge tied to the Middle East conflict, which resulted in voluntary compensation for hundreds of customers. Compliance teams in any consumer-facing sector should treat it as a signal of enforcement priorities for contract terms during market volatility.

The context matters. The CMA stepped in after some suppliers canceled orders when heating oil prices and demand surged. Hundreds of customers who ordered through an intermediary site were affected, and the CMA secured voluntary compensation from the suppliers involved. This indicates that canceling orders to take advantage of higher market prices, supported by contract terms that shield the supplier from liability, will be viewed as a fairness issue. Intermediary and platform arrangements also drew scrutiny, so responsibility across distribution chains should be reviewed.

No deadlines or compliance dates are specified. The letter is effective as a reminder from publication on 10 September 2026, and the CMA could reasonably be expected to monitor the sector and follow up. Because the matter has already involved an intervention, suppliers should assume heightened attention. The related "heating oil review" and the CMA's collection of responses to the economic impacts of the Middle East conflict suggest wider scrutiny of price-shock behavior.

Recommended actions for compliance professionals:
- Review standard terms for clauses that exclude or limit liability for cancellation, delay, or non-performance, and assess them against fairness and transparency standards.
- Confirm that terms are written in plain, prominent language and that consumers are told clearly about cancellation rights and supplier remedies.
- Examine order-cancellation procedures and decision logs for periods of price volatility, and ensure that cancellations are not driven by margin considerations without a defensible basis.
- Assess intermediary and marketplace relationships, including allocation of liability, complaint handling, and redress.
- Prepare remediation and compensation protocols, and brief senior management and the board.

Risk implications: the exposure is primarily regulatory and reputational. Unfair terms may be unenforceable against consumers, and the CMA may pursue further action beyond voluntary redress. Firms outside the heating oil sector with similar contracts, particularly in energy, fuel, and other commodity-linked supply, should consider the same lessons, since the CMA's approach is likely to carry over to other markets affected by sudden price shocks.
