The recent gazettal of the Construction Industry Security of Payment (“SOP”) Ordinance on 27 December 2024 marks a significant milestone for the construction industry in Hong Kong. This landmark legislation aims to address longstanding payment issues and enhance protections for stakeholders throughout the supply chain. Late payments and cash flow disruptions have long plagued contractors and subcontractors, often leading to project delays and financial instability. By introducing clear payment obligations and a streamlined dispute resolution process, the SOP Ordinance brings Hong Kong in line with global best practices seen in jurisdictions such as the UK, Singapore and Australia.
Key Features of the SOP Ordinance
Prohibition of Unfair Payment Terms
The SOP Ordinance prohibits payment clauses such as "pay when paid," which have historically caused delays and uncertainties in the payment chain. This ensures that all parties receive their entitled payments on time, fostering a more reliable payment environment.
Adjudication Mechanism The Ordinance introduces a speedy, cost-effective, and binding resolution process for interim payment disputes. This mechanism ensures that disputes do not hinder project progress, allowing for a more efficient and uninterrupted workflow. Adjudicators will be appointed through registered Adjudicator Nominating Bodies (ANBs), ensuring fairness and expertise in dispute resolution.
Comprehensive Coverage The SOP Ordinance applies to: Main contracts for construction works in both public and private sectors in Hong Kong valued at not less than HK$ 5 million。
Main contracts for the supply of goods or services related to construction work valued at not less than HK$ 0.5 million. Subcontracts along the same supply chain, regardless of value.
This ensures protection for all tiers of stakeholders stakeholders, from large contractors to small suppliers.
Implementation Timeline The Ordinance was gazetted on 27 December 2024, with the Secretary for Development's authority to register and administer Adjudicator Nominating Bodies (“ANBs”) taking effect immediately. The remaining provisions will come into operation on 28 August 2025, governing construction contracts entered into on or after this date.
What the Construction Industry Should Know and Do
The SOP Ordinance is expected to bring several benefits to the construction industry, including:
Timely Payments Ensuring all parties receive payments on time, reducing financial stress and enhancing cash flow stability.
Reduced Wage Arrears By addressing payment delays, the Ordinance aims to reduce the occurrence of wage arrears for workers, promoting fair labour practices.
Lower Project Procurement Costs By reducing the price premiums associated with payment risks, the Ordinance may lower overall project procurement costs.
To ensure compliance with the Construction Industry Security of Payment Ordinance when it becomes effective, here are three preliminary steps you can take today:
1. Review and amend contracts

Statutory Adjudication Mechanism: Educate your team about the statutory adjudication process for resolving payment disputes. This mechanism provides a swift, cost-effective, and binding interim resolution.
Suspension Rights: Inform your staff about the right to suspend or slow down work under certain conditions if payment disputes arise.
3. Implement robust contract administration
Documentation and Record-Keeping: Ensure that all payment claims, responses, and related documentation are meticulously recorded and managed. This will be crucial for compliance and for initiating adjudication proceedings if necessary.
Regular Audits: Conduct regular audits of your contract administration processes to ensure they align with the new requirements and to preclude liability for unmeritorious SOP claims.
