What each card colour means, how long one lasts, and what a card does and does not do for you on site.
A skills card is the construction industry’s shorthand for "this person has the training and qualifications the job needs". It is not a legal requirement in itself — no regulation says you must carry one — but most principal contractors insist on a valid card before they will let anyone through the gate, so in practice it decides whether you work.
The main card colours
- Green — Labourer. For basic non-skilled site tasks, not a substitute for a skilled trade card. A school leaver
starting as a general labourer, holding a basic site health and safety award and a pass in the operatives safety test, fits here.
- Red — Apprentice. For someone registered on a recognised apprenticeship. It gives site access
while the apprenticeship and the qualification are still in progress.
- Blue — Skilled Worker. For someone holding a relevant Level 2 vocational qualification (NVQ or
SVQ) for their own occupation. Some occupations use another CSCS Alliance scheme; check the route for the actual job rather than choosing a card by colour alone.
- Gold — Supervisory or advanced skilled work. These are separate routes with qualifications
appropriate to the role.
- Black — Manager. The senior card in the main range, for those with a management-level
vocational qualification. Do not confuse it with the gold Supervisory card.
Validity and renewal
A Blue Skilled Worker card lasts five years. A first Labourer card lasts two years; someone continuing in a labouring role can renew for five years when the renewal requirements are met, including evidence of that work. Other routes have their own validity periods.
Check the current qualification, test and renewal requirements for the card. For renewal of an initial two-year Labourer card, acceptance of the original safety test is extended to three years. Do not assume every renewal needs a new test or that every card lasts five years.
An expired card is not a card. It does not renew itself, it cannot be stretched for another few years, and it must never be lent to a colleague who has lost theirs. If yours has run out, renew it before you turn up expecting access.
Digital cards are available through the My CSCS app. Sites can verify cards using CSCS Smart Check; a photo of a card is not a substitute for checking that it is valid.
What a card does not do
A card is evidence of training and role suitability. It does not exempt you from the site induction or the site rules, it does not prove you are insured to operate plant, it does not make you an employee of the principal contractor, and it does not remove anyone’s duty to manage safety, supervise work or provide welfare facilities. The card gets you on site; everything else still applies once you are there.
