No, UK law does not name SMSTS as a requirement for site managers. However, many principal contractors and clients expect a valid CITB SMSTS certificate before you run their sites. That gap between law and hiring practice matters when you step up from supervisor.
Some people prefer to learn site safety duties before booking a CITB course. Learnera’s SMSTS Course (Site Management Safety Training Scheme) covers CDM duties, risk assessment and working at height. This CPD learning builds your knowledge at your own pace. It does not award the CITB SMSTS certificate that contractors ask for.
Key Points
- No UK law names SMSTS, yet CDM 2015 requires suitable skills, knowledge and experience.
- Many principal contractors and clients make SMSTS a site rule or contract condition.
- A CITB SMSTS certificate lasts five years, and an expired one means retaking the full course.
What Does UK Law Actually Require From Site Managers?
UK law requires competence rather than a named course. The Health and Safety at Work etc. Act 1974 places a general duty on employers. They must provide the information, instruction, training and supervision needed for health and safety.
The Construction (Design and Management) Regulations 2015 build on that duty across Great Britain. Northern Ireland follows its own CDM regulations from 2016. Under CDM 2015, contractors must check the skills, knowledge and experience of workers they appoint. That check covers the people who manage their sites.
Neither law sets out which certificate proves this. That choice sits with employers and clients. So a site manager without SMSTS is not breaking the law by holding the role. The real legal question is whether that person can manage the risks on that particular site.
Why Do Contractors Treat SMSTS As Essential?
Contractors treat SMSTS as essential because it gives them quick, recognised proof of safety training. CITB states that Build UK endorses SMSTS as the standard training for construction managers. Many large principal contractors belong to Build UK. That is why many people call SMSTS industry mandatory.
SMSTS is not the only route these rules accept, though. The Build UK Training Standard also lists alternatives such as IOSH Managing Safely in Construction. Still, check how each employer words its requirement. An advert that names SMSTS may not accept an alternative.
What Does The CITB SMSTS Course Involve?
The CITB SMSTS course is a five-day programme delivered by approved training providers. You can attend in a classroom or join live remote sessions. Topics include CDM duties, risk assessments, method statements, occupational health and managing high-risk work. CITB sets no formal entry requirements. It suggests SSSTS first if you lack health and safety management experience.
Assessment runs throughout the week. You complete core exercises and then sit a final exam of 25 questions. CITB’s scheme rules set the pass mark at 26 out of 32 marks. The certificate stays valid for five years after you pass.
Renewal needs planning. The two-day SMSTS Refresher must be completed before your certificate expires. Miss that date and you need to retake the full five-day course. Adding your expiry date to a work calendar can prevent a costly repeat.
Does An SMSTS Certificate Give You A Black CSCS Card?
No, SMSTS alone does not qualify you for the Black CSCS Manager card. The two do different jobs. Many contractors ask for both, so it helps to see them side by side.
| CITB SMSTS certificate | Black CSCS Manager card | |
|---|---|---|
| What it shows | Site management safety training | Management qualification and safety test |
| How you get it | Pass the five-day CITB course | Relevant management NVQ plus the CITB managers test |
| Validity | Five years | Five years |
The card route usually involves a construction management NVQ, such as Level 6. You also need to pass the CITB Health, Safety and Environment test for Managers and Professionals. CSCS lists the accepted qualifications on its website, so check them before you enrol.
Holding one does not cover the other. A manager with a Black card may still need SMSTS to meet a contractor’s site rules. The reverse applies too.
Check What Your Next Role Requires
The SMSTS course is not mandatory by law. Yet it often shapes who gets hired to run a site. So the practical step is to check what your target employers require.
Read the training section of a few site manager adverts in your area. Note whether they name SMSTS or accept alternatives. If you already hold the certificate, check its expiry date today. Then pick one CDM duty you feel less sure about. Studying that area now gives your formal training a stronger starting point.
Common Questions About SMSTS
Supervisors usually take the two-day SSSTS course instead. Many move on to SMSTS when they start managing sites.
Yes. CITB says delegates should hold, or be about to hold, a site manager role.
Yes, through live remote sessions with an approved provider. Self-paced online study does not lead to the CITB certificate.
CITB funding goes to registered employers, not individual workers. Ask your employer whether SMSTS qualifies under current CITB rules.
It depends on your score under CITB’s scheme rules. Some results allow a resit. Others mean repeating the full course.
