The Public Contracts Regulations 2015

Modification of contracts during their term

72.—(1) Contracts and framework agreements may be modified without a new procurement procedure in accordance with this Part in any of the following cases:—

(a) where the modifications, irrespective of their monetary value, have been provided for in the initial procurement documents in clear, precise and unequivocal review clauses, which may include price revision clauses or options, provided that such clauses—

(i) state the scope and nature of possible modifications or options as well as the conditions under which they may be used, and

(ii) do not provide for modifications or options that would alter the overall nature of the contract or the framework agreement;

(b) for additional works, services or supplies by the original contractor that have become necessary and were not included in the initial procurement, where a change of contractor—

(i) cannot be made for economic or technical reasons such as requirements of interchangeability or interoperability with existing equipment, services or installations procured under the initial procurement, or

(ii) would cause significant inconvenience or substantial duplication of costs for the contracting authority,

provided that any increase in price does not exceed 50% of the value of the original contract;

(c) where all of the following conditions are fulfilled:—

(i) the need for modification has been brought about by circumstances which a diligent contracting authority could not have foreseen;

(ii) the modification does not alter the overall nature of the contract;

(iii) any increase in price does not exceed 50% of the value of the original contract or framework agreement.

(d) where a new contractor replaces the one to which the contracting authority had initially awarded the contract as a consequence of—

(i) an unequivocal review clause or option in conformity with sub-paragraph (a), or

(ii) universal or partial succession into the position of the initial contractor, following corporate restructuring, including takeover, merger, acquisition or insolvency, of another economic operator that fulfils the criteria for qualitative selection initially established, provided that this does not entail other substantial modifications to the contract and is not aimed at circumventing the application of this Part;

(e) where the modifications, irrespective of their value, are not substantial within the meaning of paragraph (8); or

(f) where paragraph (5) applies.

(2) Where several successive modifications are made:—

(a) the limitations imposed by the proviso at the end of paragraph (1)(b) and by paragraph (c)(iii) shall apply to the value of each modification; and

(b) such successive modifications shall not be aimed at circumventing this Part.

(3) Contracting authorities which have modified a contract in either of the cases described in paragraph (1)(b) and (c) shall send a notice to that effect, in accordance with regulation 51, for publication.

(4) Such a notice shall contain the information set out in part G of Annex 5 to the Public Contracts Directive.

(5) This paragraph applies where the value of the modification is below both of the following values:—

(a) the relevant threshold mentioned in regulation 5, and

(b) 10% of the initial contract value for service and supply contracts and 15% of the initial contract value for works contracts,

provided that the modification does not alter the overall nature of the contract or framework agreement.

(6) For the purposes of paragraph (5), where several successive modifications are made, the value shall be the net cumulative value of the successive modifications.

(7) For the purpose of the calculation of—

(a) the price mentioned in paragraph (1)(b) and (c), and

(b) the values mentioned in paragraph (5)(b),

the updated figure shall be the reference figure when the contract includes an indexation clause.

(8) A modification of a contract or a framework agreement during its term shall be considered substantial for the purposes of paragraph (1)(e) where one or more of the following conditions is met:—

(a) the modification renders the contract or the framework agreement materially different in character from the one initially concluded;

(b) the modification introduces conditions which, had they been part of the initial procurement procedure, would have—

(i) allowed for the admission of other candidates than those initially selected,

(ii) allowed for the acceptance of a tender other than that originally accepted, or

(iii) attracted additional participants in the procurement procedure;

(c) the modification changes the economic balance of the contract or the framework agreement in favour of the contractor in a manner which was not provided for in the initial contract or framework agreement;

(d) the modification extends the scope of the contract or framework agreement considerably;

(e) a new contractor replaces the one to which the contracting authority had initially awarded the contract in cases other than those provided for in paragraph (1)(d).

(9) A new procurement procedure in accordance with this Part shall be required for modifications of the provisions of a public contract or a framework agreement during its term other than those provided for in this regulation.
