How to check a CSCS card before someone starts on site
A short crew on Monday morning is a problem. A crew turned away at the gate because a card is expired, the wrong type or not genuine is a bigger one. It holds up the programme, and it can leave the principal contractor questioning your site controls.
This guide sets out a practical way to check a CSCS card (or an equivalent partner scheme card) before anyone is booked. It is written for contractors, housebuilders, site managers and small trade firms in the UK.
Why check before day one
Site access rules are usually set by the principal contractor or the client, and many sites will not admit anyone without a valid card that suits the work. If you only find a problem at the turnstile, you have already lost the day.
Checking beforehand gives you time to ask for a replacement, find another operative or tell the site team what to expect. It is much cheaper to find the problem on Thursday than on Monday at 7am.
Step 1: Read the card itself
Ask the worker for a clear photo of the front and back, or look at the physical card. Then check:
- Name and photo. Does the photo look like the person in front of you, and does the name match their other ID?
- Expiry date. Is the card in date for the whole period you are booking them? A card that expires mid-job is a problem waiting to happen.
- Card type. Does it suit the role? See the next step.
- Scheme. Is it a CSCS card or a card from a partner scheme? Partner scheme cards are accepted on many sites, but not all, so check what your site requires.
- Condition. Damaged, altered or hard-to-read cards should be queried.
Step 2: Match the card to the role
Each card type shows what the holder has been assessed for. CSCS currently lists the following card types (summarised from CSCS's list of card types):
| Card type | Broadly for |
|---|---|
| Labourer | Unskilled site workers only, not skilled occupations |
| Blue Skilled Worker | Workers with a construction-related NVQ or SVQ |
| Gold Skilled Worker | Workers with a construction-related NVQ or SVQ at Level 3 |
| Supervisory | Supervisors with a construction-related supervisory NVQ or SVQ |
| Manager | Managers with a relevant construction management qualification |
| Professionally Qualified Person | Members of CSCS-approved professional bodies |
| Academically Qualified Person | Holders of certain construction-related degrees, HNDs, HNCs or CIOB certificates |
| Apprentice and Trainee | People on a recognised apprenticeship or working towards a qualification |
| Experienced Worker, and Experienced Technical, Supervisor or Manager | People with on-the-job experience who are working towards a qualification |
| Provisional and Industry Placement | Short-term cards for probation periods and work placements |
The scheme updates its card types and eligibility rules from time to time, so check the CSCS website for the full and current criteria before relying on this table.
The important question is not "is this a valid card?" but "is this the right card for this job on this site?" A labourer's card does not cover someone you want to use as a skilled groundworker or carpenter. A supervisor or site manager role usually calls for a supervisory or management card. Always check the site's own requirements.
Step 3: Verify that the card is genuine
Reading the card is not the same as verifying it. CSCS runs CSCS Smart Check, which is available as a mobile app, a website and an API, and lets employers and site teams check a card against the details CSCS holds. See the CSCS website for how to access it.
If the worker holds a partner scheme card, such as one for electricians or plant operators, use the checking method for that scheme.
If anything does not match, such as the name, expiry date or card type, do not book the worker until it has been resolved.
Step 4: Check trade tickets separately
A CSCS card does not replace trade-specific tickets. Depending on the work, you may also need to see:
- Plant cards, such as CPCS or NPORS, for the machines the operator will use. Check the category as well as the expiry date.
- Site safety training, such as SSSTS for supervisors or SMSTS for managers.
- Any other tickets your site or client requires for the task.
Check each ticket against the work you are booking them for. An excavator card does not cover a dumper, for example, unless the categories on the card say so.
Step 5: Treat CIS and right to work as separate checks
A card check says nothing about tax status or the right to work in the UK. Both need their own checks.
- CIS. If you are a contractor paying subcontractors under the Construction Industry Scheme, HMRC requires you to verify each new subcontractor before you pay them. HMRC then tells you which deduction rate to use: 20% for registered subcontractors, 30% for unregistered subcontractors, or no deduction where the subcontractor has gross payment status. See what you must do as a CIS contractor on GOV.UK.
- Right to work. Employers must check a person's right to work before employing them, following the Home Office employer's guide to right to work checks. A CSCS card is not proof of right to work.
Step 6: Keep a record
Note what you checked, who checked it and when. A copy of the card (front and back), the expiry date and the verification outcome is usually enough. If a site audit or a dispute arises later, a dated record is far better than relying on memory. Set a reminder for any card or ticket that expires during the engagement.
A quick pre-start checklist
- Photo and name match the worker's ID
- Card is in date for the whole booking
- Card type suits the role and the site's requirements
- Card verified through CSCS Smart Check or the partner scheme's checker
- Trade tickets seen, in date and the right category
- CIS status verified with HMRC (self-employed trades)
- Right to work check completed
- Copies and dates recorded
How Guild handles card checks
Guild is a construction and trades recruitment brand that checks CSCS cards (or partner scheme cards) for the right level and expiry date, confirms CIS status with HMRC for self-employed trades, and looks at trade tickets such as CPCS, NPORS, SSSTS and SMSTS. Checks marked as blocking, which are the card, CIS and right to work, must be complete before a placement can start.
We are currently building our construction and trades talent pool of groundworkers, carpenters, electricians, plant operators, labourers and site managers. Candidates register, upload a CV and add their card and tickets. Employers can create an account and tell us what they need.
FAQs
Is a CSCS card the same as a trade ticket?
No. A CSCS card shows a worker's occupation and level of qualification. Trade tickets such as CPCS or NPORS show competence on specific plant or safety training. Many roles need both.
Does a CSCS card prove someone can work in the UK?
No. Right to work needs its own check.
What should I do if a card has expired?
Don't book the worker for site work until they hold a valid, in-date card. Ask them to share the renewal details, and check the new card when it arrives.
Which card does a groundworker need?
It depends on their qualifications, experience and the site's requirements. Ask the worker which card they hold and confirm it with the site or principal contractor before booking.
Need cards and tickets checked before your next start?
Create an employer account to tell us about a role or crew requirement. Tradespeople can also register with Guild to add their CV, CSCS card and tickets, which is free for candidates.
