There are ways you can check your CSCS, CPCS or CISRS card with the CITB’s free online CSCS card checker. This is a simple and easy tool that will tell you if you have an existing card that is due for renewal, expired or will no longer be reissued due to company changes. In order to view your membership, you will need to enter some personal information into the CITB’s website. This includes your surname, national insurance number and/or your registration number. This will then generate all the details you require, such as the card itself, further course facts and any tests that may be relevant to your card.
