Construction Retention: Risks and Best Practices
What Is Construction Retention?
Construction retention is a contractual agreement where a percentage of a contractor’s payment is withheld until specific project milestones have been achieved. Its purpose is to provide financial security for the employer by ensuring any defects or incomplete work are rectified before the final payment is released.
In UK construction contracts, retention is commonly set at 3% to 5% of the contract value. Typically, half of the retained amount is released upon practical completion, with the remaining balance paid after the defects liability period has ended and all outstanding issues have been resolved.
Why Is Retention Important?
Retention benefits both clients and contractors when managed correctly.
For employers, it provides assurance that work will be completed to the required standard and that contractors remain responsible for addressing defects after completion.
For contractors, however, retained funds can place pressure on cash flow, making it essential to understand the contract terms and monitor payment milestones throughout the project.
Common Risks of Construction Retention
Delayed Cash Flow
Retention reduces the amount received during construction, which can affect a contractor’s ability to pay suppliers, labour and other project costs.
Late Release of Retention
Retention payments are sometimes delayed because of administrative issues, certification delays or unresolved defects, leaving contractors waiting longer than expected for money they have already earned.
Contract Disputes
Unclear retention clauses or disagreements over what constitutes a defect can lead to costly disputes and strained working relationships.
Insolvency Risk
If the employer or main contractor becomes insolvent before retention is released, recovering those funds may be difficult.
Best Practices
- Review retention clauses carefully before signing the contract.
- Maintain detailed project records, including inspections, completion certificates and snagging reports.
- Rectify defects promptly to avoid unnecessary payment delays.
- Track retention release dates and follow up once contractual milestones have been achieved.
- Seek Quantity Surveying advice if payment issues or disputes arise.
Expert Insight
Many retention disputes are not caused by the retention itself but by poor contract administration. Keeping accurate records, understanding contractual obligations and maintaining open communication throughout the project can significantly reduce delays and improve the likelihood of receiving retention payments on time.
Key Takeaway
Construction retention is designed to protect project quality, but it can also affect a contractor’s cash flow if not managed properly. Understanding the retention provisions within your contract, maintaining thorough documentation and monitoring payment milestones will help reduce disputes and ensure retention is released when due.
If you need support reviewing retention clauses or managing construction payments, working with an experienced Quantity Surveyor can help protect both your financial position and the successful delivery of your project.
