CSCS cards explained, and what a card does not tell you

A CSCS card is the standard proof of occupational competence on a UK construction site. Most principal contractors will not let a man through the turnstile without one, and quite right.

It is also the single most misread document in the industry, because people treat it as a general certificate of good standing. It is not. It tells you one narrow thing, and the gap between what it proves and what site managers assume it proves is where problems start.

What the colours mean

Green, Labourer. The holder has passed the health, safety and environment test and holds a Level 1 award in health and safety in a construction environment. It says nothing about skill. A green card is the right card for general labour and the wrong card for anyone you expect to work unsupervised on a trade.

Red, temporary. Several kinds sit under red. Trainee, experienced worker, experienced technical or supervisory, and provisional. What they share is that they expire and mostly cannot be renewed. A red card is a man on his way to a blue card, and the expiry date is the thing to look at.

Blue, Skilled Worker. Level 2 NVQ or equivalent in the trade named on the card. This is the standard card for a competent tradesman. The trade is printed on it and it matters: a blue card in one discipline is not evidence of competence in another.

Gold, Advanced Craft or Supervisor. Level 3 NVQ. Either an advanced craft qualification or a supervisory one, and the card says which.

Black, Manager. Level 6 or 7 in a construction management discipline. The card a site manager or contracts manager holds.

White, Academically or Professionally Qualified Person. Degrees, professional body membership, that route. Common for engineers, quantity surveyors and designers visiting site.

Plant operators sit slightly outside this. Plant work is normally evidenced by a CPCS or NPORS card for the specific category of machine, and the category codes are the part to read. A man with a 360 excavator ticket above ten tonnes is not automatically ticketed for a telehandler.

What to check on a card

The trade or category, not just the colour. The expiry date. The photograph. And whether the card is real, which is the check most people skip.

Every genuine card can be verified through the CSCS card checker, either online or with the Go Smart app that scans the chip. Counterfeit cards exist and look convincing to the naked eye. Scanning takes about eight seconds and is the only check that actually proves anything.

What a card does not cover

This is the important part.

A CSCS card is not a right to work check. Immigration status is a separate legal duty and no card colour discharges it.

It is not proof of a current medical or a drug and alcohol test.

It is not proof of insurance, and it is not proof of any trade specific ticket. A blue card electrician still needs the relevant qualification and, where the work requires it, the appropriate competent person scheme registration.

It is not proof the man is any good. Competence and quality are different things. A card gets somebody through the gate. Whether he can hang a door properly is a question the card was never asked.

How we handle it

Every operative we supply is checked for right to work, the correct card for the work, and any trade tickets the job requires, before first shift. Cards are verified against the CSCS database rather than eyeballed, and we track expiry dates so a card does not lapse mid-contract on your site.

If you want to see the checks we hold on the people already working for you, ask and we will send them.
