Part 4: Management of public contracts Modifying public contracts Section 75: Contract change notices
Subsection (1) requires a contracting authority to publish a contract change notice before modifying a public contract or a convertible contract (defined under 74(1)).
	Subsection (2) sets out specific exceptions to the requirement to publish a contract change notice prior to modification; namely when the modification (a) increases or decreases the contract value by up to 10 per cent for goods or services or up to 15 per cent for works; or (b) changes the contract term by 10 per cent or less of the maximum term provided for on award. If, however, the modification is permitted under paragraph 9 of Schedule 8 (novation or assignment on corporate restructuring), these exceptions do not apply and consequently a contract change notice must be published.
	Subsection (3) states what a "contract change notice" is and that it must contain any information required by regulations made under section 95 (notices, documents and information: regulations and online system).
	Subsections (4) and (5) have the effect that if separate modifications made using the rationale in subsections (2)(a) or (b) (where a contract change notice is not required) could reasonably have been made together with an earlier modification of the contract, a contract change notice must still be published.
	Subsection (6) sets out exceptions to the requirement to publish a contract change notice for: (a) defence and security contracts, (b) light touch contracts, (c) contracts awarded by a private utilities, (d) contracts awarded by a transferred Northern Ireland authority, unless  awarded as part of a procurement under a reserved procurement arrangement or a devolved Welsh procurement arrangement, or (e) contracts awarded as part of a procurement under a transferred Northern Ireland procurement arrangement.
	Subsection (7) grants a power allowing a Minister of the Crown or the Welsh Ministers to amend the percentage thresholds in subsections (2)(a) and (b).
