A CSCS card is not a legal requirement. The scheme says so itself: holding a card is not required by law, but most principal contractors and major house builders in the UK require one before you can work on their sites. The actual legal duty sits in the Construction (Design and Management) Regulations 2015, and it is about competence rather than cards: a contractor must not put anyone on site unless they have — or are in the process of obtaining — the skills, knowledge, training and experience for the task. Knowing the difference tells you what training actually matters.
At a glance: Nexis CPD offers £9 CPD-accredited online courses for construction workers, with a verifiable e-certificate on passing — and any three courses cost £18.

What does the law actually require?
Regulation 15 of CDM 2015 sets out the contractor’s duties. Three matter most for training:
- Regulation 15(7) — a contractor must not employ or appoint a person to work on a construction site unless that person has, or is in the process of obtaining, the necessary skills, knowledge, training and experience to carry out their tasks safely.
- Regulation 15(8) — each worker must be given appropriate supervision, instructions and information.
- Regulation 15(9)(a) — that information must include a suitable site induction, where the principal contractor has not already provided one.
Two things follow. First, the duty sits with the contractor, not only with you. Second, “in the process of obtaining” matters: the law recognises that people are trained while supervised on the job. Behind CDM sits the general employer duty in the Health and Safety at Work Act 1974 to provide information, instruction, training and supervision.
Where CSCS fits
CSCS cards show that a worker has the training and qualifications for the job they do. The scheme is owned by industry bodies — Build UK, the Civil Engineering Contractors Association, the Federation of Master Builders, Unite and GMB — and it is site rules, not legislation, that make a card effectively necessary.
Most CSCS cards require passing the CITB Health, Safety and Environment test and holding a recognised qualification for your occupation. An online CPD awareness course will not, on its own, get you a CSCS card, and you should be wary of anyone suggesting it will. Check the official CSCS website for what your card requires.

Which topics come up again and again?
Whatever your trade, a handful of hazards cause most serious harm on site, and each has its own legal training duty:
- Asbestos — anyone liable to disturb asbestos during their work needs awareness training. Buildings constructed before 2000 can contain it. See who needs asbestos awareness training.
- Work at height — falls from height remain one of the biggest causes of death in construction. See the Work at Height Regulations 2005.
- Risk assessment and method statements — understanding the RAMS you are asked to sign, rather than signing blind.
- Manual handling, COSHH, noise and dust — the cumulative harms that do not make headlines but end careers.
A practical training set for site workers
The three courses construction workers most often need together:
- Asbestos Awareness (Category A) — awareness only; it does not qualify anyone for licensed or notifiable asbestos work
- Working at Height Awareness
- Risk Assessment Awareness
Those three together cost £18 rather than £27, because any three courses trigger the pay-for-2-get-3 offer. Add them to the cart and the discount applies automatically. Health and Safety in Construction is a useful broader foundation.
Keep your certificates somewhere you control. Site managers and principal contractors increasingly ask to see training records at induction, and a certificate with a QR code they can check on the spot saves a delayed start.
Frequently asked questions
Is a CSCS card a legal requirement?
No. The CSCS scheme itself states that holding a card is not a legal requirement, but most principal contractors and major house builders in the UK require workers on their sites to hold a valid card. It is site rules rather than legislation that make a card effectively necessary for most construction work.
What training does the law require for construction workers?
Regulation 15 of the Construction (Design and Management) Regulations 2015 says a contractor must not employ or appoint a person to work on site unless they have, or are in the process of obtaining, the necessary skills, knowledge, training and experience for their tasks. Workers must also receive appropriate supervision, instructions and information, including a suitable site induction where the principal contractor has not already provided one.
Can an online course get me a CSCS card?
Not on its own. Most CSCS cards require passing the CITB Health, Safety and Environment test and holding a recognised qualification for your occupation. An online CPD awareness course is not a CSCS card, not an NVQ and not the CITB test, so check the official CSCS website for what your specific card requires.
Who is responsible for construction training, the worker or the contractor?
Both have a part, but CDM 2015 places the duty on the contractor not to put anyone on site without the necessary skills, knowledge, training and experience, and to provide supervision, instructions and a site induction. Workers also have their own duty under section 7 of the Health and Safety at Work Act 1974 to take reasonable care and co-operate with their employer.
What training topics matter most on a construction site?
A small number of hazards cause most serious harm: asbestos, which anyone liable to disturb it needs awareness training for; work at height, one of the biggest causes of death in construction; and understanding the risk assessments and method statements you are asked to sign. Manual handling, COSHH, noise and dust cause cumulative harm that ends careers.
Construction training courses
£9 per course. CPD accredited, 100% online, verifiable e-certificate. Pay for 2, get 3 — any 3 courses for £18.
This article is general information, not legal advice. Nexis CPD courses are CPD-accredited awareness courses; they are not regulated qualifications, are not NVQs, and are not equivalent to a CSCS card, the CITB Health, Safety and Environment test, NEBOSH or IOSH. Our asbestos course is Category A awareness only and does not qualify anyone for licensed or notifiable asbestos work. Online awareness training does not replace site-specific induction, practical training on equipment, or the supervision your contractor must provide.
