Your SSSTS certificate is valid for five years and must be renewed before expiry to maintain your eligibility to supervise on UK construction sites. If it expires, you will need to retake the full course. Our online SSSTS refresher alternative provides a fast and flexible way to stay compliant without classroom attendance.
COSAC’s Safe2Site Supervision Training (S2SST) offers a recognised online route designed for busy site supervisors who need to renew their knowledge and maintain compliance without taking time off work or travelling to a training centre.
The SSSTS refresher is designed for site supervisors who already hold a valid SSSTS certificate and need to update their knowledge before expiry. It ensures you remain up to date with current legislation, safety responsibilities and best practice on construction sites.
Traditionally delivered in a classroom, many supervisors now choose an online SSSTS refresher alternative such as Safe2Site Supervision Training, which delivers the same core learning outcomes in a more flexible format.
Supervisors often work under tight schedules, making it difficult to attend fixed classroom courses. An online SSSTS refresher allows you to complete your training around your workload, without disrupting site responsibilities.
