Why Take a SSSTS Refresher Course Online?

Your SSSTS certificate is only valid for five years. If you don’t renew it before it expires, you risk losing your qualification—and with it, your ability to supervise legally on UK construction sites. That’s where our Online SSSTS Refresher course comes in.

COSAC’s Safe2Site Supervision Training (S2SST) is a recognised online alternative to the SSSTS Refresher. It’s designed to help busy site supervisors maintain their certification without needing to attend a classroom course. With our fully remote, self-paced platform, you can renew your qualification from anywhere—on your schedule.

What Is the SSSTS Refresher Course?

The Site Supervision Safety Training Scheme (SSSTS) Refresher is a one-day training course that must be completed before your current SSSTS certificate expires. It ensures that you remain up to date with legislation, safety responsibilities, and best practice on site.

Traditionally, the refresher has been delivered in person. However, COSAC now offers a CITB-recognised online alternative through our Safe2Site Supervision Training. It delivers the same learning outcomes—without requiring you to take time off work or travel to a test centre.

Why Choose the Online SSSTS Refresher With COSAC?

As a site supervisor, you already know how tight schedules can be. Attending a full-day in-person course can be a real challenge—especially when deadlines, logistics, and team responsibilities are at stake.

COSAC’s Online SSSTS Refresher course gives you everything you need to stay compliant, without putting your job on hold.

Benefits of our online SSSTS Refresher alternative:

• Start immediately – No need to wait for classroom dates
• Train anytime – Study on your own schedule, from any device
• No travel required – Complete the course from home or site
• Self-paced format – Stop and start as needed, without pressure
• Recognised outcome – Fully CITB, JIB, and ECS approved
• Quick certification – Get your certificate within 24 hours of passing

Who Needs an Online SSSTS Refresher Course?

This course is ideal for:

• Site supervisors with a valid SSSTS certificate that is about to expire
• Subcontractors who need a fast and flexible renewal option
• Employers looking to keep staff compliant without downtime
• Professionals working remotely or outside easy reach of a test centre
• Supervisors who prefer to train in a quiet, self-managed environment

Note: If your SSSTS certificate has already expired, you will need to take the full SSSTS course again. Renew early to avoid disruption.

What Does the Online SSSTS Refresher Cover?

The COSAC Online SSSTS Refresher course is aligned with CITB standards and covers the full range of required topics to maintain your status as a qualified site supervisor.

The content includes:

• Legal responsibilities under the Health and Safety at Work Act
• Site supervision duties under CDM 2015 Regulations
• Conducting and reviewing risk assessments
• Methods of enforcing site safety and improving culture
• Communication and toolbox talks
• Behavioural safety, reporting, and supervision techniques

Each module is interactive, with clear explanations and real-world examples that help you apply the content to your day-to-day responsibilities on site.
