Betting and Gaming Duties Act 1981

10 (1) Where in the case of any track or other premises an officer has reason to believe that bookmaking on events taking place thereon is being or is to be carried on, or that facilities for sponsored pool betting on those events are being or are to be provided, or that a totalisator is being or is to be operated in connection with those events, at a place on those premises or on any ground or premises adjacent thereto, he shall be entitled for the purpose of exercising the powers conferred by this paragraph to be admitted without payment to that place, and he may require—

(a) any person who appears to him to be or intend carrying on bookmaking, providing such facilities or operating a totalisator there to give such information as he may demand and to produce to him any accounts, records, or other documents which appear to him to be connected with the business of bookmaking or with the provision of those facilities or the operation of that totalisator or which it appears to him will establish the identity of that person; and

(b) any person who appears to him to have made a bet there with any bookmaker, or through the persons providing any such facilities, or by means of a totalisator, to give such information with respect to the bet as he may demand and to produce to him any document in connection with the bet supplied to that person by the bookmaker, the persons providing those facilities, or the operator of that totalisator, as the case may be,

and any such person as aforesaid shall comply with any such requirement.

(2) Where an officer—

(a) has reason to believe that any person who is not a bookmaker is holding himself out as mentioned in section 12(1) of this Act at any place, and

(b) has reason to suspect that person to have become liable by virtue of that section to pay an amount by way of general betting duty or pool betting duty,

the officer shall have the like powers with respect to that place as if the person so holding himself out were a bookmaker and that place were such a place as is mentioned in sub-paragraph (1) above.
