The launch of a comprehensive market study by the Competition and Markets Authority (CMA) into the retail supply of heating oil for domestic use marks a significant step towards addressing concerns over pricing volatility and availability in this essential market. As of March 2026, approximately £2.3 billion was spent on heating oil by UK households not connected to the main gas grid, highlighting the substantial financial burden faced by these consumers.
With prices subject to fluctuation and rural households often bearing higher costs due to limited supply options, the investigation aims to examine how competition functions within this market. Key areas of focus will include price-setting mechanisms, transparency of charges, and potential barriers to entry for new suppliers. The CMA's review is expected to shed light on issues that have sparked growing public concern over consumer affordability.
A broad range of stakeholders has contributed their insights to the CMA's information-gathering process, including prominent industry bodies such as UKIFDA and BoilerJuice, alongside consumer advocacy groups like Citizens Advice, Citizens Advice Scotland, Consumer Scotland, and charities focused on fuel poverty. The inputs have underscored the wide-reaching impact of heating oil costs across different segments of society.
The study is scheduled to conclude with a final report by July 2026, potentially outlining recommendations for market improvements. If competition issues are identified, this could lead to regulatory interventions aimed at safeguarding consumer interests. The statutory deadline for completing the study falls on 19th March 2027.
This regulatory initiative underscores the CMA's dedication to fostering fair and competitive markets that benefit all consumers. Its outcomes may have far-reaching implications for thousands of households relying on heating oil, particularly those in rural areas where access to affordable energy is a pressing concern.
