2025 has been a milestone year for COSAC and Safe2Site. As the original pioneers of fully online CSCS training – and as a CITB Approved Training Organisation – we’ve continued to lead the industry with fast, flexible, and accessible e-learning trusted across the UK.
This year, over 45,000 learners successfully completed their qualifications with us, maintaining our exceptional 98% pass rate and receiving their certificates within just 24 hours. We also maintained our 4.9-star rating across both Google and Trustpilot.
2025 saw a significant rise in the number of B2B clients choosing COSAC as their primary training partner. Construction companies, labour suppliers, and subcontractors relied on us for:
Businesses choose us because our process is simple, efficient, and designed to reduce downtime – getting workers site-ready without delays through trusted site safety training and recognised qualifications.
Our customer support team has continued to be a major reason learners choose COSAC. With evening and weekend availability, fast responses, and expert guidance, customers consistently praise us for:
This unmatched level of support helped maintain our excellent 4.9-star rating across all major platforms.
Before online construction training became mainstream, COSAC had already developed digital-first solutions that challenged traditional classroom models. Our Safe2Site Online CSCS Green Card course remains one of the most trusted ways to gain your CSCS training quickly and flexibly.
Years of experience delivering site safety training have enabled us to continually improve the learner experience while maintaining high standards of quality and compliance.
A major highlight this year was the continued growth of Safe2Site Premium, our all-in-one package that offers a seamless journey from training to assessment. It remains one of the most convenient ways to complete all requirements for the CSCS Green Card in one place.
By combining training, assessment support, and certification guidance, Safe2Site Premium simplifies the CSCS training process for individuals and businesses alike.
2025 also saw more supervisors and businesses choosing Safe2Site Supervision – our online alternative to the SSSTS classroom course. Designed for easier access, better flexibility, and quicker completion, it has become a leading choice for those needing a supervisor-level qualification without the limitations of traditional training.
For organisations looking to develop management skills, our site supervisor training programme offers practical knowledge focused on compliance, leadership, and workplace safety. Many learners also choose it as an alternative route to a traditional SSSTS supervisor course.
The cost of an SSSTS supervisor course varies depending on the provider, training format, and location. Classroom-based courses typically range from £200 to £400, while online alternatives may offer greater flexibility and cost savings. Learners should always compare course content, accreditation, and support when choosing supervisor training.
The best course for construction depends on your role and career goals. New entrants often begin with CSCS training and health and safety qualifications, while experienced workers may progress into site supervisor training or management programmes. Choosing CITB approved courses helps ensure qualifications are recognised by employers and meet current industry standards.
These achievements reflect our ongoing commitment to delivering accessible site safety training and supporting workforce development across the UK construction industry.
As we move into 2026, our focus remains on doing what we do best: offering fast, accessible, and reliable training that helps learners and businesses move forward confidently. We aim to:
We remain committed to building training that is practical, efficient, and designed for real-world construction needs. This includes expanding access to CITB approved courses, enhancing CSCS training pathways, and supporting future site supervisor training requirements.
As we reach the end of 2025, we want to say a genuine thank you to all the learners, companies, and partners who have trusted COSAC this year. Your success is the foundation of everything we do.
Whether you were entering the construction industry, renewing qualifications, becoming a supervisor, or upskilling your staff, we’re proud to have been part of your journey through quality site safety training and recognised qualifications.
From all of us at COSAC, we wish you a Merry Christmas, a peaceful festive season, and a very Happy New Year. Here’s to a safe, successful, and productive 2026.
