# The Motor Fuel Price (Open Data) Regulations 2025, Regulation 20: Determination of turnover and daily turnover


(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.
(4) Where the figures necessary to calculate the turnover of the undertaking under paragraph (3)(a) or (b) are not available to the CMA on the relevant date, the turnover of the undertaking is its turnover in the period beginning with the day after the last day of its relevant accounting period and ending with the last day of the month preceding the month in which the relevant date falls.
(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.
