What Is a CSCS Blue Card?
The Skilled Worker Card — proof that a UK construction tradesperson holds a recognised NVQ Level 2 qualification for their trade.
Quick Answer
The CSCS Blue Card (officially the Skilled Worker Card) is a Construction Skills Certification Scheme card for UK tradespeople who hold an NVQ Level 2 or equivalent qualification in their trade, plus the CITB Health, Safety and Environment test. It is the most common card held by qualified tradespeople — electricians, bricklayers, carpenters, plumbers, plasterers, and more — and is valid for 5 years.

Frequently Asked Questions
What is the difference between a CSCS Blue Card and a Green Card?
Green Card = labourers who passed the HS&E test only, no trade qualification. Blue Card = qualified tradespeople with NVQ Level 2+ and the HS&E test. Blue Card is the next level up and confirms the holder is a trained tradesperson.
Can I work on site without a CSCS Blue Card?
You can if the site doesn't enforce CSCS requirements, but most major UK construction sites require all workers to hold the appropriate CSCS card. Turning up without a card will often result in you being refused site access.
What qualifications count towards a CSCS Blue Card?
Recognised qualifications include NVQ Level 2, City & Guilds diplomas, EAL awards, and equivalent SCQF Level 5 qualifications (Scotland). JIB-registered electricians qualify through JIB/ECS cards, which are part of the CSCS scheme.
How long does it take to get a CSCS Blue Card?
Once you have your NVQ and have passed the HS&E test, the card application typically takes 5–14 working days. Test results are usually instant at the test centre.
How much does a CSCS Blue Card cost?
The CSCS card application fee is currently £36. The CITB HS&E test costs approximately £22. The NVQ itself varies — employer-funded apprenticeships cost nothing to the worker, while adult NVQ routes cost between £200 and £1,500 depending on the awarding body and route.
