The Motor Fuel Price (Open Data) Regulations 2025

These Regulations, made under the Data (Use and Access) Act 2025, establish a mandatory open data scheme requiring motor fuel traders in England, Wales, Scotland, and Northern Ireland to register their petrol filling stations and report the selling price of motor fuels to an appointed third-party 'aggregator'.

Motor fuel traders must provide this price information, including any subsequent changes within 30 minutes of occurrence, for public dissemination via an Application Programming Interface (API) and other means.

The Competition and Markets Authority (CMA) is responsible for enforcement, with powers to issue compliance notices, conduct investigations, impose financial penalties up to 1% of worldwide turnover, and pursue criminal sanctions for false information or obstruction.

Arguments For

  • Establishes a transparent open data scheme for motor fuel prices, enhancing consumer choice and market competition.

  • Mandates timely reporting of price changes (within 30 minutes) via an aggregator, ensuring data accuracy and immediacy.

  • Provides the Competition and Markets Authority (CMA) with robust monitoring, investigatory, and enforcement powers, including the ability to issue compliance notices and impose significant financial penalties.

  • Defines clear registration requirements for motor fuel traders, ensuring all retail outlets are identified and tracked within the data scheme.

  • Includes a mandatory quinquennial review mechanism to ensure the Regulations remain appropriate and effective over time.

Arguments Against

  • Imposes significant administrative and technical burdens, especially around timely data submission (30-minute window),

  • The calculation of financial penalties based on the worldwide turnover of the undertaking could result in disproportionately high fines for minor or inadvertent breaches.

  • Introduces new criminal offences related to obstructing information access, potentially broadening regulatory liability beyond simple non-compliance.

  • Requires capital investment by traders to comply with data provision channels (e.g., API access), which could strain small independent businesses.

  • The staggered commencement dates (December 2025 and February 2026) create complexity during the initial implementation phase.

The Secretary of State makes these Regulations in exercise of the powers conferred by section 4(1)(b) and (4)(b), (c) and (d), 5(3)(a), (4)(a), (b), (c) and (e), (7)(a), (8) and (9), 7(1), (4)(d), (g), (j), (k) and (l) and (5), 8(1) to (11) and (13), 10, 18, 19 and 21(1) of the Data (Use and Access) Act 2025.

In deciding to make these Regulations, the Secretary of State has had regard to the matters mentioned in section 4(5) of that Act.

The Secretary of State has carried out the consultation required by section 22(3) of that Act before making these Regulations.

In accordance with section 22(1)(b) and (d) of that Act, a draft of these Regulations was laid before and approved by a resolution of each House of Parliament.

(7) Regulation 20 (determination of turnover and daily turnover) applies for the purposes of determining the turnover and daily turnover, both inside and outside the United Kingdom, of the undertaking which the motor fuel trader constitutes or of which it forms part.

Determination of turnover and daily turnover 20. (1) Subject to paragraphs (3) to (6), the turnover of an undertaking is its turnover in— (a) the last accounting period to end before the relevant date (its “relevant accounting period”), or (b) where the undertaking has no accounting period that ends before the relevant date, the period beginning with the day on which the activities of the undertaking began to be carried on and ending with the last day of the month preceding the month in which the relevant date falls.

(2) Where the CMA estimates on the relevant date that the turnover of the undertaking in the accounting period immediately preceding its relevant accounting period (the “preceding accounting period”) was higher than the turnover of the undertaking in its relevant accounting period, the turnover is its turnover in the preceding accounting period.

(3) Where the figures necessary to calculate the turnover of the undertaking in its relevant accounting period are not available to the CMA on the relevant date, the turnover is, subject to paragraph (4), its turnover in— (a) the preceding accounting period, or (b) where the undertaking has no preceding accounting period, the period beginning with the day on which the activities of the undertaking began to be carried on and ending with the day immediately preceding the date on which its relevant accounting period began.

(5) Where the period by reference to which turnover is calculated does not equal 12 months, the turnover of the undertaking is the turnover in that period divided by the number of days in that period and multiplied by 365 or, where the period includes 29th February, 366.

(6) The daily turnover of the undertaking is the turnover divided by 365 or, where the period by reference to which turnover is calculated includes 29th February, 366.

(7) For the purposes of this regulation— (a) an “accounting period” of an undertaking is a period of more than six months in respect of which accounts are prepared or required to be prepared in relation to the undertaking; (b) the “relevant date” means the date on which the notice of intent is issued under regulation 21(1) (notice of intent to impose financial penalty); (c) the provisions of Schedule 2 apply in the determination of turnover.
