Getting onto a Preferred Supplier List (PSL) can be a great way to secure regular business. It doesn’t guarantee work, but it puts you in a position to be considered whenever opportunities arise. Here’s how to approach the process.

Understand the Requirements

Every PSL has its own criteria. Common requirements include:

Evidence of relevant experience or case studies

Proof of insurances, accreditations, or certifications

Policies such as health & safety, data protection, or equality & diversity

Before you apply, make sure you fully understand what’s expected. Read any guidance carefully and note deadlines.

Prepare Your Documents

A PSL application often requires more than a simple form. You may need:

Company overview

Financial stability information

References or client testimonials

Evidence of previous projects

Having these documents ready in advance saves time and ensures your application is complete.

Follow the Application Instructions

Some PSLs require online submission, others via email or post. Make sure you follow the instructions exactly. Missing documents or incorrect formatting can disqualify you.

Pay attention to deadlines and plan your time accordingly — even “quick” applications can take a few days to prepare properly.

Highlight Your Strengths

Think about what makes your business different. Are you faster, more reliable, or specialised in a certain area? Make sure your application demonstrates these points clearly.

Be concise, factual, and honest, don’t overcomplicate it with jargon. The goal is to make it easy for the client to see why you should be on their list.

Maintain Relationships

Even after you submit, it helps to maintain a professional relationship with the organisation. Follow up politely if appropriate, and make sure they know you’re available for questions.

Plan for Renewal

PSLs often run for a fixed period (e.g., 2–3 years). Keep track of renewal dates and be ready to update your information when the next application window opens.
