Fuel Oil: Competition

Asked by Laura Kyrke-SmithLabourDepartment for Energy Security and Net ZeroTabled Answered 16 March 2026UIN 119767

The question

To ask the Secretary of State for Energy Security and Net Zero, (i) what steps he is taking to improve transparency and competitiveness in the heating oil market, and (ii) what protections and monitoring he is putting in place for consumers that use the heating oil market.

Answered by Martin McCluskey

Heating oil customers are not tied to a single supplier and can shop around for the best price, supported by commercial price comparison websites. Unlike gas and electricity, heating oil is bought on the spot market, making it more exposed to short‑term volatility in global oil prices, which we recognise is a significant concern for those reliant on it.

We continue close engagement with industry to ensure pricing is fair and transparent, the CMA is ready to act against any unfair or anti‑competitive behaviour. We are keeping under review whether any further action may be needed to protect consumers.
