If you work in construction and want to step into a supervisory role, the SSSTS course online gives you the legal knowledge, safety responsibilities, and practical skills you need — all without leaving your home or job site.
This guide breaks down every module covered in the course, who it is designed for, and what you can do with the qualification once you complete it.
What Is the SSSTS Course Online?
The Site Supervisors’ Safety Training Scheme (SSSTS) is a two-day qualification accredited by CITB. It trains construction workers to supervise teams safely and legally on UK sites.
The SSSTS course online delivers the same nationally recognised qualification as classroom training. You complete the theory modules through a virtual learning environment, then attend a short assessment session to receive your certificate.
It is the industry-standard qualification for anyone moving from a trade operative role into a site supervisor position.
Who Should Take the SSSTS Course?
The course is designed for:
- Construction workers moving into a supervisory role for the first time
- Experienced supervisors who need to renew an expired SSSTS certificate
- Site managers who want a refresher on current UK health and safety legislation
- Subcontractors who need to demonstrate compliance to principal contractors
- Anyone who oversees two or more workers on a live construction site
You do not need any prior health and safety qualifications to enrol. The course starts from the basics and builds to a confident understanding of your legal duties as a supervisor.
Full Module Breakdown: What the SSSTS Course Online Covers
The SSSTS course online covers seven core subject areas over two days. Here is a detailed breakdown of each module.
Module 1 — Health and Safety Law
This module gives you a clear understanding of UK construction legislation and your personal responsibilities under it.
You learn about:
- The Health and Safety at Work Act 1974 and what it requires from supervisors
- The Construction (Design and Management) Regulations 2015 (CDM 2015)
- The Management of Health and Safety at Work Regulations 1999
- Your duty of care to workers, visitors, and members of the public
- The consequences of failing to meet legal obligations — including prosecution and fines
Understanding the law is the foundation of everything else in the course. You cannot supervise safely if you do not know what the law requires of you.
Module 2 — Risk Assessment and Method Statements
Supervisors are responsible for making sure risk assessments exist for every activity on site. This module teaches you how to read, apply, and brief workers on them.
You learn about:
- The five steps of a risk assessment
- How to write a basic method statement (RAMS)
- Identifying hazards before work starts
- Communicating risks clearly to your team through toolbox talks
- Reviewing and updating assessments when site conditions change
This is one of the most practical modules in the SSSTS course online because supervisors use these skills every single working day.
Module 3 — Accident Prevention and Reporting
Construction is the UK’s most dangerous industry. This module focuses on how supervisors actively prevent accidents rather than simply react to them.
You learn about:
- The causes of the most common construction accidents — falls from height, struck-by incidents, and manual handling injuries
- Near miss reporting and why it matters
- RIDDOR 2013 — what must be reported, to whom, and within what timeframe
- How to conduct a basic incident investigation
- The role of the supervisor when an accident happens on site
Module 4 — Welfare and Worker Health
UK law requires specific welfare facilities on every construction site. Supervisors are responsible for ensuring those facilities are available and maintained.
This module covers:
- Minimum welfare requirements under the CDM Regulations
- Occupational health risks — including silica dust, hand-arm vibration, and noise exposure
- Control of Substances Hazardous to Health (COSHH) and what supervisors must do
- Mental health awareness on site and the supervisor’s role in early intervention
- Managing fatigue, shift patterns, and worker wellbeing
Module 5 — Inductions and Toolbox Talks
Every worker on site must receive a site induction. Supervisors usually deliver them. This module teaches you how to do it effectively.
You learn about:
- The required content of a site induction under CDM 2015
- How to deliver a toolbox talk that workers actually understand and remember
- Keeping accurate records of inductions and briefings
- Communication techniques for multi-language teams
- How to check understanding and confirm workers are competent before they start
Module 6 — Permits to Work and Site Control
High-risk activities on construction sites require a formal permit to work system. Supervisors must understand how to operate within that system.
This module covers:
- Types of permits to work — hot works, confined spaces, excavations, and working at height
- The supervisor’s role in issuing, checking, and closing permits
- Site rules, security, and access control
- Managing subcontractors and ensuring they comply with site requirements
- Coordinating with the principal contractor and other trades
Module 7 — Environmental Responsibilities
Construction sites generate significant environmental impact. This module ensures supervisors understand their environmental duties under UK law.
You learn about:
- Waste management and the duty of care for construction waste
- Preventing pollution — water, noise, and dust controls
- Environmental legislation relevant to construction sites
- Reporting environmental incidents
- Sustainable working practices that reduce site impact
How Is the SSSTS Course Online Assessed?
At the end of the two days, you complete a written assessment. The test consists of multiple-choice questions covering all seven modules.
You also complete a short personal action plan — a written commitment to how you will apply what you have learned in your supervisory role.
Both elements must be passed to receive your SSSTS certificate.
What Do You Get When You Pass?
Once you pass the SSSTS course online, you receive:
- A CITB SSSTS certificate — valid for five years
- A card that proves your qualification to employers and principal contractors
- Recognition of your supervisory competence across UK construction sites
The certificate is widely accepted across the construction industry as proof that you are a competent, legally aware site supervisor.
How Long Does the Certificate Last?
Your SSSTS certificate is valid for five years. Before it expires, you must complete an SSSTS Refresher course to renew it.
The refresher is a one-day course and covers any updates to legislation or industry guidance since you last qualified. Many supervisors book the refresher before their certificate expires to avoid a gap in their qualifications.
SSSTS vs SMSTS — What Is the Difference?
The SSSTS course online is designed for supervisors who directly oversee operatives on site.
The SMSTS (Site Management Safety Training Scheme) is a five-day course designed for site managers and project managers who hold overall responsibility for health and safety across the site.
If you supervise a team, you need SSSTS. If you manage the site, you need SMSTS. Many construction professionals complete SSSTS first, then progress to SMSTS as their career advances.
