An SMSTS certificate is valid for five years from the date you pass. To keep it valid, you take the SMSTS Refresher, a two-day course, before the expiry date.

If you let it lapse, you will normally need to book the full five-day SMSTS course again. That is three extra days away from site, so it pays to plan ahead.

Set a reminder now Put your expiry date in your phone calendar with a reminder six months before. Many site managers only find out their certificate has lapsed when a contractor asks for it.

What the refresher covers

The refresher updates you on law changes and good practice, and goes back over the core of the full course: CDM duties, risk management, and how to lead safety on a busy site. It ends with an exam, so treat it seriously.

Mistakes that cost people their SMSTS

Most people lose their certificate simply because they forget when it runs out. Five years is long enough to change employer, phone and email, and the reminder gets lost.

  • Booking the refresher after expiry. Once the certificate has lapsed, you normally have to retake the full five-day course instead of the two-day refresher.
  • Leaving it to the last month. Refresher dates can be busy. Aim to book three to six months ahead.
  • Losing your certificate details. Keep a photo of your certificate and your CITB details. You will need them to book the refresher.
  • Assuming your employer tracks it. Some do, many do not. It is your certificate, so track it yourself.

A simple renewal plan

  1. On the day you pass, add your expiry date to your phone calendar with two reminders: six months and three months before.
  2. At six months, ask your employer whether they will fund the refresher.
  3. At three months, book the two-day refresher, classroom or online.
  4. Bring your current certificate details to the course.
  5. After passing, add the new expiry date to your calendar straight away.
