(1) In respect of the functions regulated by section 17 of the 1988 Act, the matter specified in section 17(5)(e) of that Act ceases to be a non-commercial matter but only to the extent that either paragraph (2) or (3) applies.
(2) This paragraph applies where, before inviting the submission of tenders, a relevant authority determines that contractors not based within the United Kingdom may not participate in the procurement of a relevant contract.
(3) This paragraph applies where, before inviting the submission of tenders, a relevant authority determines that contractors not based within the local area may not participate in the procurement of a relevant contract.
(4) For the purposes of paragraphs (2) and (3) a contractor is “based within” a location where that contractor is based or has established substantive business operations, not taking account of the location of the corporate ownership or control of the contractor.
(5) For the purposes of paragraph (3), “the local area” is—
(a) where there is one relevant authority which intends to enter into a relevant contract—
(i) the area of that authority, or
(ii) the area specified in (i) and any of the areas of the counties or London boroughs that border that area;
(b) where there are two or more relevant authorities which intend to enter into a relevant contract—
(i) the areas of those authorities, or
(ii) the areas specified in (i) and any of the areas of the counties or London boroughs that border those areas.
(6) For the purposes of sub-paragraphs (a)(i) and (b)(i) of paragraph (5), where the relevant authority is wholly located within a single county or London borough, the area of that authority may be either—
(a) the area of the authority, or
(b) the area of the single county or London borough that the authority is located within.
(7) For the purposes of paragraph (5), the area of a relevant authority is determined by reference to where the authority primarily exercises its functions, disregarding any areas outside of the United Kingdom.
(8) Where the relevant authority advertises for the purpose of inviting tenders in accordance with either paragraph (2) or paragraph (3), the authority must specify which paragraph applies, and (where paragraph (3) applies) the extent of the local area for the purposes of paragraph (5)—
(a) in respect of a notifiable below-threshold contract, in the below-threshold tender notice, and
(b) in respect of all other relevant contracts, in the advertisement.
