Holding a CSCS card is not a legal requirement in the UK, but CSCS's own guidance confirms cleaners working on a live construction site are expected to hold one -- a Labourer (green) card for general site cleaning, or a Skilled Worker (blue) card for specialist cleaning roles -- while cleaners working only in site offices or welfare facilities away from the live site do not need one.
Is a CSCS card a legal requirement?
No -- there is no legal requirement in UK law to hold a CSCS card. It is an industry-standard scheme that most principal contractors and site operators choose to require for access to a live construction site, as part of their own site rules and health and safety management.
When does a cleaner need a CSCS card?
According to CSCS's own guidance, published on cscs.uk.com, 'CSCS cards are required when a cleaner is working on a live construction site.' A card is not required when a cleaner is working somewhere that isn't a live site -- such as site offices or welfare facilities -- although site managers should still induct, and where appropriate escort, non-construction workers.
Which CSCS card do cleaners need?
CSCS points cleaners toward two card types depending on the work: a Labourer card for general on-site cleaning duties, such as clearing construction debris and keeping the site tidy, and a Skilled Worker (blue) card for specialist cleaning roles such as industrial cleaning, which requires a Level 2 Certificate in Cleaning and Support Services Skills to apply.
What if a site insists every cleaner needs a card, even in welfare areas?
CSCS has publicly acknowledged that some sites insist everyone must hold a card regardless of role, which can result in legitimate non-construction workers being incorrectly refused entry. It remains the site manager's responsibility to induct and manage access for workers who fall outside the official card requirement.
