Summary
A site induction is the first thing that happens to anyone setting foot on a notifiable or multi-contractor construction site — before they pick up a tool, before they walk past the hoarding. It is a short, structured briefing that tells the worker what the specific hazards are on this site, where the welfare and first aid are, what to do if the alarm sounds, what PPE is mandatory, and what the site rules are. It is not the same as a toolbox talk and it is not optional paperwork: under CDM 2015 it is a legal duty, and the records you keep are the evidence that the duty was discharged.
The induction exists because every site is different. A worker may be fully trained and CSCS-carded, but they do not know that the south scaffold is condemned, that the only fire exit is round the back because the front is blocked by the muck-away, or that there is a confined-space permit system in operation. The induction transfers that site-specific knowledge before exposure to the risk, which is exactly what the Health and Safety at Work etc. Act 1974 and CDM 2015 require of those in control of the work.
For a sole trader or small firm working under a principal contractor, the induction is something you receive and sign. When you are the one running the site — the principal contractor on a project with more than one contractor — the induction is something you must provide, record, and keep current as the site and its hazards change. This article covers both sides: what a good induction contains, who is responsible under CDM 2015, the records you must keep, and how inductions differ from toolbox talks.
Key Facts
- CDM 2015 — the Construction (Design and Management) Regulations 2015 are the principal health and safety regulations for construction work in Great Britain. They define the dutyholders and their responsibilities.
- Regulation 13 (principal contractor duties) — the principal contractor must plan, manage and monitor the construction phase and ensure every worker is given a suitable site induction.
- Regulation 15 (contractors' duties) — each contractor must not start work until satisfied their workers have received a suitable site induction and any further necessary information and training.
- Health and Safety at Work etc. Act 1974 — the overarching statute; Section 2 (duty to employees) and Section 3 (duty to others) underpin the requirement to inform and instruct.
- Who needs one — every worker, subcontractor, delivery driver entering the working area, and every visitor. No exceptions; "I was only here ten minutes" is not a defence.
- When — before the person starts work or enters the working area for the first time. Re-induction is needed after a long absence or when site conditions change significantly.
- Principal contractor — appointed in writing by the client where there is more than one contractor. On single-contractor projects that contractor takes on the relevant duties.
- Principal designer — coordinates health and safety in the pre-construction (design) phase; feeds residual design risks into the information used at induction.
- Construction phase plan — required on every CDM project; the induction communicates its site rules and arrangements to the workforce.
- F10 notification — projects lasting longer than 30 working days with more than 20 workers simultaneously, or exceeding 500 person-days, must be notified to the HSE on form F10.
- Welfare (Schedule 2) — CDM 2015 Schedule 2 sets minimum welfare facilities (toilets, washing, drinking water, rest areas); the induction tells workers where they are.
- Induction record — a signed register of who was inducted, when, and by whom; retained as evidence of compliance.
- Toolbox talk — a short, focused talk on a single topic, repeated periodically; distinct from the one-off general induction.
- Domestic clients — on domestic projects the client's CDM duties normally pass to the contractor (or principal contractor); inductions still apply to the workforce.

Detailed Guidance
Who is responsible under CDM 2015
The duty depends on the project structure. Where a project has more than one contractor, the client must appoint a principal contractor in writing. That principal contractor carries the Regulation 13 duty to ensure every worker on site receives a suitable induction and that the construction phase is planned, managed and monitored. Each individual contractor then carries the Regulation 15 duty: they must not let their own people start work until satisfied those people have been inducted.
On a single-contractor project, there is no principal contractor — the sole contractor takes on the relevant duties, including making sure their workers are inducted and informed.
WHO RUNS THE INDUCTION?
More than one contractor on the project?
YES -> Client appoints PRINCIPAL CONTRACTOR (in writing)
-> PC ensures EVERY worker is inducted (Reg 13)
-> Each contractor ensures its own workers inducted before start (Reg 15)
NO -> Single contractor takes on the duties
-> That contractor inducts its workers
Domestic client?
-> CDM client duties normally pass to contractor / PC
What a good induction covers
A site induction is site-specific. A generic "health and safety video" is not enough on its own — it must tell the worker about this site. The core content:
- Site rules and management — who is in charge, sign-in/out procedure, working hours, no-go and restricted areas, permit-to-work systems, and the smoking/vaping and drugs-and-alcohol policy.
- Site-specific hazards — the actual risks present: deep excavations, live overhead or buried services, asbestos surveys and any ACMs, traffic and plant routes, fragile roofs, working at height, confined spaces.
- Welfare arrangements — where the toilets, washing facilities, drinking water and rest area are (CDM Schedule 2).
- First aid — names of the first aiders, where the kit and any defibrillator are, and how to raise the alarm.
- Fire and emergency — the alarm signal, escape routes, the assembly point, and the procedure for reporting an emergency.
- PPE — the minimum PPE for the site (typically hard hat, hi-vis, safety boots, eye protection) plus task-specific requirements.
- RAMS — confirming the worker has access to and understands the relevant risk assessments and method statements for their work.
- Reporting — how to report incidents, near misses, and unsafe conditions, and the expectation that they will.
Records and registers
The induction is only as good as the evidence it happened. Keep an induction register: name, company, date, who delivered the induction, and the worker's signature confirming they understood it. Many sites issue an induction sticker for the worker's hard hat or a signed induction card so supervisors can see at a glance who has been through. The register is what you produce if the HSE asks, or if there is an incident and you need to show the worker was briefed on the hazard involved.
Retain the records for the life of the project at minimum, and longer where health risks (asbestos, noise, vibration) may have a long latency. The register also drives re-induction: anyone who has been off site for an extended period, or who started before a major change to the site, needs re-inducting.
Inductions vs toolbox talks
These are often confused. The induction is the one-off, comprehensive briefing a person gets before they first work on the site — it covers everything above. A toolbox talk is a short (often 10–15 minute), focused session on a single topic — manual handling, working near excavations, a recent near miss, a change in the weather plan — delivered repeatedly through the project to keep specific risks front of mind.
INDUCTION TOOLBOX TALK
One-off, before first work Repeated, ongoing
Comprehensive, site-wide Single focused topic
Mandatory under CDM Reg 13/15 Good practice / risk-driven
Signed register Attendance record
You need both. The induction gets people safely onto the site; toolbox talks keep them safe as the work and hazards evolve.
Frequently Asked Questions
Does a delivery driver need an induction?
If they enter the working area, yes — at least a short visitor or driver induction covering traffic routes, the assembly point, PPE and where they may and may not go. A driver who stays in the cab in a segregated, controlled delivery bay may need only a cut-down briefing, but anyone walking into the live site needs inducting. The principal contractor decides the level based on the risk the visitor is exposed to.
How often do you need to re-induct someone?
There is no fixed legal interval. Re-induction is triggered by significant change: a long absence from site, a major change in site layout or hazards (a new phase, demolition starting, a new excavation), or where competence or understanding is in doubt. Many principal contractors also refresh inductions periodically on long projects as a matter of good practice.
Is a site induction a legal requirement on a domestic job?
CDM 2015 applies to domestic projects, but the client's duties normally transfer to the contractor or principal contractor. The duty to inform and instruct workers under the Health and Safety at Work etc. Act 1974 and CDM still applies, so workers on a domestic site must be inducted to the site's hazards even if the homeowner is the "client" on paper.
Who can deliver a site induction?
Someone competent and familiar with the site — usually the principal contractor's site manager or a nominated supervisor. The person delivering it must know the site's actual hazards and arrangements; reading a generic script without site knowledge defeats the purpose.
What happens if there is no induction and someone is hurt?
The dutyholder who failed to induct (typically the principal contractor under Reg 13, or the contractor under Reg 15) is exposed to enforcement action by the HSE — improvement or prohibition notices, prosecution, and unlimited fines on conviction. The absence of an induction record is strong evidence that the duty to inform and instruct was not discharged.
