SSSTS Refresher Course — Duration, Cost & What to Expect

The Site Supervisors Safety Training Scheme (SSSTS) is the UK construction industry's recognised qualification for site supervisors and front-line managers who are responsible for day-to-day safety supervision on construction sites. The initial SSSTS is a two-day course that covers health and safety law, risk assessment, method statements, accident reporting, and safe systems of work. The SSSTS certificate and associated card are valid for five years, after which the holder must complete the SSSTS Refresher Course to renew their certification and maintain recognised supervisor status.

The SSSTS Refresher is a one-day course rather than a full two-day repeat of the initial training. This reflects the fact that the refresher is designed to update existing knowledge rather than teach concepts from scratch. The course revisits key health and safety principles, focuses on updates to legislation or guidance since the previous training cycle, and reinforces best practices that experienced supervisors apply on site. Most providers run the refresher at their own training centres, at employer sites, or at construction industry venues, with both weekday and occasional weekend options available depending on demand.

The SSSTS card is recognised within the CSCS (Construction Skills Certification Scheme) card scheme, which is the main card system used across UK construction sites to demonstrate that workers and supervisors have appropriate safety training. Many main contractors and construction clients require all site supervisors to hold a current CSCS card, and the SSSTS-backed Supervisor card satisfies that requirement for the supervisory role.

Allowing an SSSTS card to lapse — by not completing the refresher within the five-year window — means the supervisor no longer holds a recognised supervisor-level card and may be restricted from site access under contractor safety policies.

Booking the SSSTS Refresher Course should be planned at least four to six weeks before the current certificate expires, as popular courses fill quickly in high-demand regions. CITB publishes a list of approved training providers who deliver the SSSTS and SSSTS Refresher through its website, and many providers offer online booking. Some employers organise group refresher bookings for multiple supervisors at once, which may attract a discounted rate from the training provider.

Finally, the SSSTS Refresher certificate confirms to clients, principal contractors, and main contractors that the supervisor has fulfilled their CDM 2015 and industry best-practice obligations. Keeping the certificate current is one of the simplest and most practical steps a supervisor can take to protect both their own site access rights and their employer's contractual compliance position.

This guide covers everything you need to know about the SSSTS Refresher Course — what it covers, how long it takes, what it costs, what to expect on the day, and how to ensure your renewal goes smoothly.

The SSSTS Refresher is a legal and professional necessity for anyone operating in a supervisory role on UK construction sites under the CSCS card system. Most tier-one contractors include a current, recognised CSCS card as a minimum site access requirement in their subcontract agreements, and supervisors who cannot produce a valid card on site are typically barred from entry until the card situation is resolved.

This means that an expired SSSTS certificate and card is not merely a paper compliance issue — it is a practical barrier to site access that can affect the supervisor's ability to work and their employer's ability to deploy them on certain sites.

The cost of the SSSTS Refresher is generally considered modest in the context of construction industry training costs. At £150–£250 per delegate, the refresher represents a small investment relative to the value of maintaining site supervisor status and the CSCS card. Employers with CITB levy registration may be eligible for a grant contribution toward the course cost — CITB periodically updates its grant rates for approved training, and checking the current grant position before booking is worthwhile for registered employers. Some training providers also offer early-booking or group discounts that further reduce the cost per delegate.

For supervisors who work across multiple construction companies or who are self-employed, maintaining the SSSTS certificate and CSCS card independently — rather than relying on an employer to arrange training — is particularly important. Self-employed supervisors should track their own certificate expiry date and arrange their own refresher booking rather than assuming that a client or main contractor will prompt them. Allowing the certificate to lapse can make the supervisor ineligible for certain contracts or roles until they have completed the renewal.

The SSSTS was introduced by CITB as part of a broader drive to professionalise safety management in the UK construction sector. Before schemes like SSSTS and SMSTS were established, there was no consistent national standard for construction site supervisor safety competency. The SSSTS programme created a reproducible, assessable framework that has become the industry's benchmark for front-line supervisory safety training. The scheme's longevity reflects genuine industry confidence in its content and its alignment with the CDM Regulations and other major UK construction safety legislation.

Supervisors who hold the SSSTS and are considering career progression should be aware that SMSTS (Site Management Safety Training Scheme) is the natural next step. SMSTS covers site management responsibilities at a higher level — including the principal contractor role under CDM 2015, site-wide safety management planning, and the management of multiple supervisors. SSSTS provides an excellent foundation for SMSTS, and experienced SSSTS supervisors often find the step up to SMSTS manageable with preparation. Both certifications together position a construction professional well for site manager and project manager roles.

The SSSTS Refresher also serves a welfare function beyond strict compliance. Construction sites have among the highest fatality and injury rates of any UK industry, and the regular five-year renewal cycle ensures that supervisors remain current with the latest health and safety guidance and case law that shapes best practice on site. The refresher content is updated by CITB periodically to reflect changes in legislation, published accident investigations, and emerging site safety risks — meaning the course a supervisor attends today covers content that was not available when they completed their initial SSSTS.

Supervisors returning to construction after a career break — for parental leave, health reasons, or time in a different industry — should prioritise getting their SSSTS status up to date before resuming supervisory duties. In addition to the refresher course, they may benefit from a brief self-directed review of any major CDM or HSE guidance updates issued during their absence, which their SSSTS trainer can usually advise on during the course.

The SSSTS Refresher Course covers the same core subject areas as the initial two-day SSSTS training, but at a faster pace and with a focus on reinforcement and updates rather than ground-up instruction. The course typically runs from approximately 8:30 AM to 5:00 PM and is delivered in a classroom setting with a maximum of around 12–20 delegates per session, depending on the provider. Small group sizes allow for discussion-based learning and the sharing of site experience among delegates, which is a distinctive feature of CITB-managed training.

The course content covers current health and safety legislation as it applies to construction site supervision — including the Health and Safety at Work Act 1974, the Construction (Design and Management) Regulations 2015 (CDM 2015), the Management of Health and Safety at Work Regulations 1999, and other relevant statutory frameworks. Delegates review the supervisor's legal duties under these regulations, the hierarchy of risk controls, the content requirements for risk assessments and method statements, and the accident and incident reporting obligations under RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations).

A significant portion of the refresher is typically dedicated to case studies and practical scenarios that test delegates' ability to apply legislation to real-world site situations. These scenarios might involve reviewing a risk assessment for a specific work activity, identifying shortcomings in a method statement, or determining the appropriate response to a near-miss incident. This practical application approach helps delegates connect the legislative content to the decisions they make on site rather than treating safety management as a purely academic exercise.

The refresher course concludes with a short written assessment, similar to the assessment at the end of the initial SSSTS course. The assessment tests knowledge of the key legislative and procedural content covered during the day. Most delegates who attend and engage with the course material pass the assessment without difficulty. Providers typically mark and return results on the same day, and delegates who pass receive confirmation that their certificate will be renewed. The updated SSSTS certificate is typically issued within a few days to a few weeks after the course, depending on the provider's administration process.

Delegates who do not pass the refresher assessment may be offered a resit opportunity, either on the same day (if time allows) or on a future course date. Providers generally allow one or more resit attempts, though the specific policy varies. For delegates who are concerned about the assessment, reviewing basic health and safety principles, CDM 2015 responsibilities, and RIDDOR reporting requirements before attending the course is the best preparation strategy.

Some providers also offer virtual or blended delivery options for the SSSTS Refresher, combining an online pre-course module with a shorter face-to-face assessment session. Check with your chosen provider whether virtual options are available and whether they are accepted by your employer or main contractor — some contractors require in-person attendance for CSCS-related training.

The SSSTS Refresher can also be completed by supervisors whose certificate has lapsed — those who missed the five-year renewal window. Lapsed certificate holders are generally accepted onto refresher courses rather than being required to repeat the full two-day initial course, provided the lapse has not been excessive.

Providers apply their own policies on how long after expiry a refresher is acceptable; supervisors whose certificate lapsed more than two or three years ago may be asked to retake the full initial course. If uncertain about your eligibility for the refresher rather than the initial course, contact your chosen provider before booking.

The assessment at the end of the SSSTS Refresher is not intended to catch delegates out. It is a straightforward test of the day's content — primarily health and safety law, risk assessment principles, and CDM 2015 requirements. Delegates who attend the full day and engage with the material rather than watching passively should find the assessment manageable. The most useful preparation is simply reviewing the RIDDOR thresholds (what types of injuries must be reported and to whom) and the CDM 2015 duty holder roles (client, principal designer, principal contractor, contractor, and worker) before arriving for the course.

Feedback from supervisors who have completed the SSSTS Refresher consistently highlights that one of its most valuable aspects is the opportunity to discuss safety challenges with peers from other organisations and sites. Because delegates come from different construction companies and project types, the group discussions during case studies surface a range of experiences and approaches to common site safety problems. This peer exchange is difficult to replicate in self-study and is one reason that CITB-managed training emphasises classroom delivery over purely online formats for the SSSTS scheme.

Understanding the CDM 2015 Regulations in depth is central to the refresher content. Specifically, supervisors should be clear on their role as a site operative and supervisor versus the roles of the principal contractor and the CDM coordinator (principal designer in CDM 2015 terms). The refresher tests whether supervisors understand which responsibilities fall to them directly — maintaining safety standards in their work area, conducting toolbox talks, completing risk assessment documentation — versus which responsibilities sit with the principal contractor or designer. This distinction is consistently tested in refresher assessments.

Method statements — also called Safe Systems of Work (SSoW) or WPPs (Work Package Plans) in some contractual contexts — are a recurring topic throughout the SSSTS refresher. Supervisors should understand what a compliant method statement must contain (scope of work, sequence of activities, resources required, hazards identified, controls in place, emergency procedures), how to review a method statement for adequacy before work begins, and how to ensure operatives have been briefed on its contents before commencing work. Practical method statement review exercises are common in refresher course case study sessions.

For supervisors who have moved roles, changed employers, or been on extended leave since their initial SSSTS, the refresher is also an opportunity to reconnect with the current state of UK construction safety legislation, which is periodically updated through revisions to the approved codes of practice (ACOPs), the HSE's guidance, and industry sector agreements. The refresher trainer typically highlights any significant updates that have occurred since the last SSSTS revision cycle, which keeps experienced supervisors current without requiring them to independently track regulatory changes.

After the course, the provider submits the successful delegate's results to CITB for registration, and the updated SSSTS certificate is typically issued within 2–4 weeks. The certificate is sent by post or electronically depending on the provider. Supervisors should update their employer's training records and apply for a new CSCS Gold Supervisor card as soon as the updated SSSTS certificate is received, particularly if the current CSCS card is due to expire in the near future.

The SSSTS Refresher is also a useful opportunity for supervisors to network with peers from other construction firms and to gain perspective on how different organisations approach site safety management. The informal conversations during breaks and group exercises can surface practical approaches to common challenges — near-miss reporting culture, operatives' engagement with toolbox talks, subcontractor briefings — that are valuable regardless of the legislative content.
