How to Do a Site Induction for Construction: Complete UK Guide
Everything you need to run effective site inductions on construction projects. What to cover, how to record it, and how to keep it practical instead of a box-ticking exercise.
TL;DR
- • On multi-contractor projects, the principal contractor ensures a suitable induction; on every project, each contractor covers workers under its control unless the PC already has.
- • Cover site rules, hazards, welfare facilities, emergency procedures, PPE requirements, and reporting.
- • Keep a dated record as useful evidence; CDM 2015 does not prescribe a signed induction form.
- • HSE guidance calls for visitor inductions proportionate to the visit, with less detail for escorted visitors.
- • Keep it practical and site-specific — cover the actual hazards, rules and emergency arrangements before work starts.

What is a site induction?
A site induction gives workers the site-specific information they need before starting work. Contractors must cover workers under their control unless a principal contractor has already provided the induction; HSE guidance also covers proportionate visitor inductions. Its purpose is to explain the hazards, rules and emergency procedures for that particular site — not construction in general, but this site, this project.
Think of it as the “welcome to site” briefing. A qualified electrician might have 20 years of experience, but they have never been on your site before. They do not know where the live services run, where the welfare facilities are, or what the emergency assembly point is. The induction fills those gaps.
A site induction is different from general health and safety training. It is not about teaching someone how to use a circular saw or explaining the hierarchy of control. It is about giving them the site-specific information they need to work safely on your project from day one.
What is the legal basis for site inductions?
Site inductions are required under several pieces of legislation, but the primary ones for construction are:
- CDM 2015, Regulation 13(4)(a) — on a project with more than one contractor, requires the principal contractor to ensure a suitable site induction is provided.
- CDM 2015, Regulation 8 — requires those appointing designers or contractors to take reasonable steps to ensure they have the necessary skills, knowledge, experience and organisational capability.
- Management of Health and Safety at Work Regulations 1999, Regulation 10 — requires employers to provide employees with comprehensible information on risks and preventive measures.
- Health and Safety at Work etc. Act 1974, Section 2 — the overarching duty on employers to provide information, instruction, training, and supervision to ensure safety.
The HSE’s L153 guidance explains the site-specific content that a suitable induction should cover. Regulation 13(4)(a) itself requires the principal contractor on a project with more than one contractor to ensure a suitable site induction is provided.
Who needs a site induction?
Start with every worker under a contractor’s control. They need a suitable induction unless the principal contractor has already provided it. HSE guidance also recommends proportionate inductions for occasional and once-only visitors. In practice, consider:
- Your own employees and direct labour.
- Subcontractors and their workers — electricians, plumbers, roofers, plasterers, scaffolders.
- Agency and temporary workers.
- Delivery drivers entering the site area.
- Visitors — clients, architects, structural engineers, building control officers.
- Homeowners on domestic projects who need to access parts of their property.
The depth of the induction varies depending on the person’s role. A bricklayer joining the site needs the full induction. A delivery driver dropping off a pallet of blocks needs a shorter briefing covering the key hazards, traffic routes, and unloading area. A visiting building control officer needs to know about PPE requirements, current hazards, and who to report to.
The critical point is that workers receive the information required for their work, while visitors receive a briefing proportionate to their visit and whether they are escorted.
What should a site induction cover?
The content of your induction should be tailored to the site, but here are the core topics that every construction site induction should address:
Site rules and access
Working hours, site boundaries, access and egress points, parking arrangements, speed limits on site, no-go areas, and rules about alcohol, drugs, and smoking. Make it clear what happens if someone breaks the rules.
Welfare facilities
Location of toilets, hand-washing stations, drinking water, rest and eating areas, changing facilities, and drying rooms. On domestic jobs, explain whether the homeowner has agreed to provide access to their facilities and any conditions on that arrangement.
Emergency procedures
What to do in an emergency: fire alarm location and assembly point, how to raise the alarm, location of fire extinguishers, first-aid kit location, name and location of the first-aider, nearest A&E, and the site address for emergency calls. If there is a specific evacuation route, walk it during the induction.
Site-specific hazards
The key hazards on this particular site. For example: open excavations, overhead power lines, fragile roofs, asbestos-containing materials, confined spaces, live services, or adjacent occupied buildings. Point these out during a site walk-around wherever possible.
PPE requirements
The minimum PPE required on site at all times (typically hard hat, safety boots, hi-vis) and any additional PPE required for specific areas or tasks (eye protection near cutting, ear protection near noisy plant, dust masks in enclosed spaces).
Permits and reporting
Any permit-to-work systems in operation (hot works, confined spaces, excavation). How to report hazards, near-misses, and accidents. Who to report to. Explain that reporting is not about getting people in trouble — it is about preventing someone getting hurt.
How to deliver the induction effectively
A site induction is only effective if the person actually takes the information on board. Reading a laminated sheet in a portacabin while someone waits impatiently for a signature is not an effective induction. Here is how to do it properly:
Deliver it face-to-face. A site manager, foreman or whoever is running the site can deliver the induction person-to-person. This allows the new person to ask questions and gives you a chance to gauge whether they have understood. On larger sites, group inductions are fine for the standard content, but try to include time for individual questions.
Include a site walk-around. Do not just talk about hazards — show them. Walk the new person around the site and physically point out the excavations, the scaffold access points, the welfare facilities, the first-aid kit, and the emergency assembly point. Showing the actual locations helps workers identify where those site arrangements apply.
Keep the language simple. Not everyone on site has English as their first language. Use plain words, avoid jargon, and check understanding by asking questions: “If there was a fire, where would you go?” “Who would you tell if you spotted a hazard?” If someone does not understand, find a way to communicate — whether that is through a colleague who speaks their language, visual aids, or a translated summary.
Keep it relevant. Do not pad the induction with generic health and safety waffle. Every minute of the induction should be about this site and this project. A focused induction should cover the actual hazards and controls on this site rather than relying on a generic lecture.
How to record and sign off inductions
CDM 2015 does not prescribe a written or signed induction form. Keeping a dated record of who was inducted, when, what was covered and who delivered it is still sensible evidence. A signature can confirm receipt, but it does not replace checking understanding.
At a minimum, your induction record should capture:
- Full name of the person being inducted.
- Company they work for (if a subcontractor).
- Date and time of the induction.
- Name of the person who delivered the induction.
- Topics covered (use a checklist).
- Signature of the inductee confirming they understood the information.
- CSCS card number and expiry (if applicable).
Traditionally, this is done on a paper form kept in a site folder. The problem with paper is that it gets lost, damaged by rain, or left in the van. Digital sign-off — where the inductee signs on a tablet or phone — stores records automatically with the project, so you can retrieve them during an audit or HSE inspection.
How to handle visitor inductions
HSE guidance says site inductions should also be provided to people who visit occasionally or once. The detail should match the visit: escorted visitors need only the main hazards and controls they may encounter, while unescorted visitors need more information.
A visitor induction should cover:
- PPE requirements — provide a hard hat, hi-vis, and safety glasses if required.
- Areas they can and cannot access — keep visitors away from active work zones.
- Who they must be accompanied by at all times.
- Key hazards they need to be aware of (open excavations, overhead work, plant movements).
- Emergency procedures — fire assembly point, exit routes.
Keep the visitor briefing proportionate to the visit and cover the hazards and arrangements that affect that person. Record the visitor’s name, the date, and the time in a visitor log. Some sites use a separate visitor sign-in book for this purpose. The important thing is that you know who is on your site at any given time and that they have been briefed on the basics.
When do you need a refresher induction?
A site induction is not a one-and-done exercise. Conditions on site change — new hazards appear, work phases shift, and emergency procedures may be updated. There are several situations where a refresher induction is warranted:
- A significant change in site conditions — for example, a new phase of demolition introducing asbestos risks, or deep excavation work starting.
- A worker returns to site after a prolonged absence (more than a few weeks).
- New safety procedures are introduced — such as a new permit-to-work system or changed traffic management.
- An incident or near-miss has occurred that highlights gaps in understanding.
- On longer projects, review whether workers need a refresher as the work and risks change.
A refresher does not have to repeat the entire induction from scratch. Focus on what has changed and why. Cover the new hazards or updated procedures, allow questions and check understanding. Record it just like the original induction.
Site induction template: what to include
A good site induction form serves two purposes: it guides the person delivering the induction (so nothing gets missed), and it provides a record for your files. Here is a practical template structure you can use:
Header: project and site details
Project name, site address, principal contractor name, site manager name and phone number. This information stays the same for every induction on the project.
Inductee details
Full name, employer/company, trade, CSCS card number and expiry date (if applicable), next of kin and emergency contact number.
Induction checklist
A list of topics to be covered, each with a tick box. This ensures the person delivering the induction does not skip anything. Topics should include: site rules, working hours, PPE requirements, welfare facilities, emergency procedures, first-aid arrangements, site-specific hazards, reporting procedures, permits to work, and environmental controls (dust, noise, waste).
Declaration and sign-off
A statement along the lines of: ‘I confirm that I have received a site induction, I understand the information provided, and I will comply with the site rules.’ Space for the inductee’s signature, date, and the inductor’s signature.
Competence check (optional but recommended)
A few simple questions to check the inductee was actually listening. For example: ‘Where is the fire assembly point?’ ‘What PPE is required at all times?’ ‘Who do you report a hazard to?’ Use the answers to check understanding and revisit any point that is unclear.
Common mistakes with site inductions
Site inductions are one of the most basic safety measures on a construction site, yet they are frequently done poorly. Here are the mistakes we see most often:
- Treating it as a form-filling exercise. Handing someone a sheet to read and sign is not an induction. The information needs to be explained and understood.
- Using a generic induction that is not specific to the site. Every site is different. The induction must cover the actual hazards, facilities, and procedures on this particular project.
- Not keeping a useful record. A dated note of who attended and what was covered helps evidence the briefing; a signature alone does not prove understanding.
- Skipping inductions for subcontractors. A qualified electrician still needs a site induction — they know their trade, but they do not know your site.
- Forgetting visitors. HSE guidance recommends a briefing proportionate to the visit, with only the main hazards and controls needed for escorted visitors.
- Not updating the induction content when site conditions change. If new hazards appear, the induction should reflect them.
Frequently asked questions
Is a site induction a legal requirement?
Yes. On a project with more than one contractor, CDM 2015 regulation 13(4)(a) requires the principal contractor to ensure a suitable site induction is provided. On every project, regulations 15(8) and 15(9)(a) require each contractor to provide every worker under its control with appropriate supervision, instructions and information, including a suitable site induction where the principal contractor has not already provided one.
How long should a site induction take?
There is no fixed legal duration for a site induction. Allow enough time to explain the rules, welfare, emergency arrangements, first aid, reporting route and hazards the worker will encounter. Walk the site where that helps show a location or control, invite questions and check understanding before work starts. Keep the content relevant to this project and record who attended and what was covered.
Do visitors need a site induction?
HSE guidance says occasional and once-only visitors should receive an induction proportionate to their visit. Escorted visitors need only the main hazards and controls they may encounter; unescorted visitors need more detail. A practical visitor briefing can cover PPE, restricted areas, who accompanies them and emergency procedures.
Can I do a site induction verbally or does it need to be written?
The induction can be delivered verbally, and a spoken briefing with a site walk-around can be effective. CDM 2015 does not prescribe a written or signed induction form. A dated record of the person, topics covered and who delivered it is still sensible evidence, and a signature can help confirm receipt without replacing a check that the worker understood.
How often do I need to redo site inductions?
There is no fixed legal interval for refresher inductions, but good practice is to consider a refresher when conditions on site change significantly (for example, a new phase of work introducing new hazards), when someone has been away from the site for a prolonged period (more than a few weeks), or when new safety procedures are introduced. On longer projects, review whether workers need a refresher as the work and risks change. The key principle is that workers must have current, relevant information about the hazards and procedures that affect their work.
What PPE do I need to provide for the induction?
You do not necessarily need to provide PPE for the induction itself, but you must ensure that anyone going on site has the appropriate PPE. The minimum requirement varies by site, but typically includes a hard hat, safety boots, and a hi-vis vest. Eye protection, ear protection, gloves, and dust masks may be needed depending on the work being done. Under the Personal Protective Equipment at Work Regulations 1992 (as amended), employers must provide PPE free of charge to their employees. For subcontractors, it is their employer’s responsibility — but you should check they have the right kit before allowing them on site.
Site inductions — how to do them so workers actually remember
Pros
- A site induction explains the rules, hazards and emergency arrangements workers need for this project.
- A clear dated record helps show what workers were told, but it does not replace a suitable briefing and check of understanding.
- Inductions set site culture on day one — PPE, welfare, working hours, reporting all get normalised up-front.
- Keep the briefing focused on site-specific information, allow questions and check that workers understand the controls relevant to their tasks.
Cons
- Boilerplate inductions can omit the local risks workers need to understand.
- Missing site-specific items (fragile roof, first aid room, assembly point) = the induction is worthless.
- Re-inductions for returning workers are often skipped — but site changes mean re-induction matters.
- HSE guidance calls for proportionate inductions for occasional and once-only visitors, with less detail for escorted visitors.
| Topic | Covered? | Notes |
|---|---|---|
| Site rules (PPE, hours, welfare) | Always | Must include the non-negotiables. |
| Site-specific hazards + controls | Always | Fragile roof, excavation, overhead cables. |
| Emergency procedures | Always | Assembly point, nearest A&E, first aider name. |
| RIDDOR + near-miss reporting | Always | How, to who, deadline. |
| Welfare facilities | Always | Location, cleanliness, drinking water. |
| Ask a site walk | Recommended | Seeing the risks in person matters most. |
