Construction and engineering are high-risk industries, so giving your supervisors proper safety training isn’t optional — it’s how you meet your legal duties and keep people safe. Two qualifications come up for first-line supervisors and team leaders: the Site Supervisor Safety Training Scheme (SSSTS) and CCNSG Leading a Team Safely. They sound interchangeable, but they belong to different schemes and suit different sectors — and one has an entry requirement the other doesn’t. Here’s how to pick the right one.
The key difference up front
SSSTS is the CITB supervisor qualification for the construction industry — required by BuildUK for supervisors on their sites, and taken as a standalone two-day course. CCNSG Leading a Team Safely is a one-day ECITB top-up within the engineering-construction safety passport scheme, aimed at the engineering, utilities and energy sectors — and it requires you to already hold a valid CCNSG Safety Passport. So the choice usually comes down to which sector and scheme your site operates under, not simply course length.

Which one is right for your supervisors?
Choose SSSTS
The standard two-day CITB qualification for construction site supervisors and team leaders. Required by BuildUK, no prerequisites, and the recognised stepping stone toward the SMSTS for those heading into site management.
Choose CCNSG Leading a Team Safely
The one-day ECITB top-up for supervisors already working under the CCNSG safety passport scheme on engineering, energy or utilities sites — building team-leadership and safety skills on top of the Safety Passport they already hold.
Frequently asked questions
Is SSSTS or CCNSG Leading a Team Safely better?
Neither is “better” — they suit different sectors. SSSTS is the construction-industry standard (CITB, required by BuildUK). CCNSG Leading a Team Safely is for the engineering, utilities and energy sectors that run under the ECITB safety passport scheme. Choose based on where your supervisors work.
Do I need a Safety Passport before Leading a Team Safely?
Yes. CCNSG Leading a Team Safely requires you to already hold a valid two-day CCNSG Safety Passport. It’s a one-day top-up, not a standalone qualification. SSSTS, by contrast, has no entry requirement.
How long does each qualification last?
The SSSTS certificate is valid for five years, renewed with a one-day SSSTS Refresher. The CCNSG scheme runs on a three-year cycle, renewed through the CCNSG Safety Passport renewal rather than separately.
Can a construction supervisor take Leading a Team Safely instead of SSSTS?
For most construction sites, SSSTS is what’s expected, because BuildUK specifies it. Leading a Team Safely is aimed at the engineering-construction and utilities sectors. If you’re unsure what your site or client requires, check before booking.
What comes after SSSTS?
Many supervisors progress from SSSTS to the five-day SMSTS as they move into site management, or toward a Construction NVQ.
