LONDON – The UK Competition and Markets Authority (CMA) is initiating court-based enforcement action against heating oil suppliers who refuse to compensate customers after a wave of order cancellations and aggressive repricing.
The intervention follows a market-wide review triggered by extreme volatility in global energy markets, which left approximately 1,700 households facing unexpected costs. The regulator confirmed that while some firms have already agreed to provide restitution, it will pursue legal remedies against those resisting compensation claims, using its powers under the UK competition and consumer protection regime.
This regulatory friction highlights a systemic vulnerability for the 1.5 million UK households dependent on heating oil. Unlike domestic gas and electricity users, these consumers operate outside the protection of the Ofgem energy price cap, leaving them fully exposed to wholesale price swings and the contractual practices of individual distributors. Many of the affected households are low- to middle-income families that must pay for deliveries up front, magnifying the impact of any short-notice change in terms.
Contractual failures and consumer loss
The dispute centers on a pattern of behavior where suppliers cancelled existing orders during a period of rapid price inflation, subsequently offering new quotes at significantly higher rates. In some instances, households were forced to re-order at inflated prices or risk a total loss of fuel, despite having believed they had already secured a confirmed delivery.
The financial impact on affected consumers reached up to £350 per household. These losses occurred as retail prices peaked 92% higher, driven by geopolitical instability in the Middle East and the disruption of shipping routes through the Strait of Hormuz, with wholesale benchmarks such as Brent crude spiking sharply over a short period.
“We’ve heard troubling reports from heating oil customers about cancelled orders and sudden price increases – and are moving quickly to get to the bottom of these concerns,” said Sarah Cardell, Chief Executive of the CMA.
The CMA is specifically probing two primary areas of concern:
- The cancellation of confirmed orders followed by the issuance of higher quotes, and whether customers were clearly informed of their rights at the point of sale.
- Sudden price increases applied to automated deliveries, which are triggered by tank sensors when fuel levels drop, raising questions over how and when contractual terms can be varied.
Systemic regulatory gaps
The reliance on heating oil is geographically concentrated, with a significant impact in Northern Ireland, where 62.5% of homes depend on the fuel, compared to a UK average of just over 5%. Because these households often reside in rural or off-grid areas, they face limited supplier competition, higher logistics costs, and fewer practical alternatives when deliveries are cancelled at short notice.
The current market structure allows for rapid price adjustments based on global crude benchmarks. However, the CMA found that the lack of a proportionate regulatory regime has allowed what it describes as “clear gaps” in protection, particularly regarding how prices are quoted and how cancellations are managed under the Consumer Rights Act 2015. That legislation sets out core rights around fair contract terms, transparency and the delivery of services with reasonable care and skill, providing the legal backdrop for any challenge to unilateral changes in agreed prices.
Officials say the episode also exposes a wider policy question for government: whether essential off-grid heating fuels should be brought under a more formal oversight regime, akin to arrangements in the regulated gas and power markets, to prevent similar disputes during future energy shocks.
Proposed regulatory framework
To mitigate future volatility, the CMA has recommended a new regulatory regime to ensure fair treatment during periods of market instability. This framework would shift the industry toward a more transparent, registered model of operation, with clearer lines of accountability between small local distributors and larger wholesale suppliers.
The proposed standards include:
| Requirement | Objective |
|---|---|
| Supplier Registration | Ensure all firms meet minimum operational and ethical standards and can be held to consistent rules across the UK. |
| Quote Transparency | Standardize how prices are quoted, when they can be revised, and how cancellations are handled, including clear timelines and redress routes. |
| Vulnerability Register | Create a formal mechanism to provide additional support to at-risk households, such as elderly customers or those reliant on heating oil for medical needs. |
| Volume Review | Assess minimum order volumes to allow smaller, more affordable purchases, reducing the risk of bill shocks for cash-constrained consumers. |
The CMA is now preparing formal enforcement proceedings against non-compliant firms while awaiting the government’s response to its recommendations and a decision on whether to adopt the proposed regulatory regime. Any move to legislate or extend sector-style regulation to heating oil would require coordination between Westminster and the devolved administrations, and is likely to form part of the wider political debate over how the UK protects off-grid households during the next phase of the energy transition.
