These systems can dramatically reduce the effort required to access opportunities while increasing your chances of winning contracts.

What Are PSLs and Frameworks?

Preferred Supplier Lists (PSLs): A vetted group of suppliers approved to deliver goods or services to a company. Buyers often invite only PSL members to quote, making these lists a shortcut to tender opportunities.

Framework Agreements: Pre-negotiated contracts or arrangements with multiple suppliers. Buyers use frameworks to quickly procure goods or services without going through a full tender each time.

Being on a PSL or framework gives your business direct access to projects, often before they are advertised publicly.

Why You Should Target PSLs and Frameworks

Repeat opportunities – once accepted, you can bid for multiple projects under the same framework.

Reduced competition – fewer suppliers are invited to quote compared with open tenders.

Trusted status – being on a list signals credibility, compliance, and reliability.

Streamlined process – frameworks simplify procurement procedures and speed up decision-making.

Strategic relationships – build ongoing partnerships with buyers for long-term contracts.

How to Access PSLs and Frameworks

Identify relevant frameworks and PSLs, look at your sector, target organisations, and geographic focus.

Check eligibility requirements, some lists require certifications, insurances, or financial stability.

Submit applications, provide company details, capability statements, case studies, and references.

Maintain compliance, keep certifications, insurances, and records up to date.

Respond to invitations, once approved, you’ll receive project-specific invites or mini-competitions.

Track performance, frameworks often include review or scoring systems to maintain your position on the list.

Tip: Being on a PSL or framework doesn’t guarantee work, but it gives you exclusive access to the procurement process for multiple projects.

How to Make PSLs and Frameworks Work for Your Business

Prioritise high-value or strategic frameworks – focus on lists that align with your capabilities and growth goals.
