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

• Every person entering a construction site needs a site induction before they start work — no exceptions.
• Cover site rules, hazards, welfare facilities, emergency procedures, PPE requirements, and reporting.
• Record each induction in writing with a signature — verbal-only inductions leave you exposed.
• Visitors need a shorter induction covering key hazards and areas they must not enter.
• Keep it practical and site-specific — 15–20 minutes is enough for most domestic and small commercial jobs.

What is a site induction?

A site induction is a briefing given to every person before they start work on a construction site. Its purpose is to make sure everyone understands the specific 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 — requires the principal contractor to provide each worker with suitable site-specific information, instructions, and training before they begin work on site.
CDM 2015, Regulation 8 — requires all duty holders to provide information, instruction, and training as necessary to ensure health and safety.
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 Approved Code of Practice (ACOP L153) for CDM 2015 specifically states that the principal contractor should ensure site inductions are carried out. While the word “induction” does not appear in the regulation itself, the ACOP makes clear that an induction is the expected way to deliver the required information.

Who needs a site induction?

The simple answer: everyone. Every person who sets foot on a construction site needs an appropriate induction before they start any activity. This includes:

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 who will be on site for six weeks 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 no one should be working on or walking around your site without having received an induction appropriate to what they are doing there.

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. The best inductions are given person-to-person by the site manager, foreman, or whoever is running the site that day. 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. People remember what they see far better than what they hear.

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 15-minute focused induction is far more effective than a 45-minute lecture where people switch off after 10 minutes.

How to record and sign off inductions

Recording your site inductions is not optional. You need a written record that shows who was inducted, when, what was covered, and that they confirmed their understanding. Without this record, you have no evidence the induction took place — and in the eyes of the HSE, if it is not recorded, it did not happen.

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 — solves this by storing records automatically in the cloud, making them easy to find during an audit or HSE inspection.

How to handle visitor inductions

Not everyone who comes to your site is there to do construction work. Architects popping in to check progress. Building control doing an inspection. The homeowner wanting to see how their kitchen is looking. Delivery drivers dropping off materials. All of them need an induction — but it does not have to be the full version.

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.

This takes about 5 minutes and can be delivered at the site entrance. 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 (6+ months), a periodic refresher every 3–6 months is good practice.

A refresher does not have to repeat the entire induction from scratch. Focus on what has changed and why. A 5–10 minute briefing covering the new hazards or updated procedures is usually enough. 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?’ This takes 2 minutes and significantly improves the quality of the induction.

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 recording the induction. If you cannot prove it happened, it may as well not have happened. Always get a signature.
Skipping inductions for subcontractors. A qualified electrician still needs a site induction — they know their trade, but they do not know your site.
Forgetting visitor inductions. Anyone entering the site needs an appropriate briefing, even if they are only there for 20 minutes.
Not updating the induction content when site conditions change. If new hazards appear, the induction should reflect them.

Frequently asked questions

Common questions about construction site inductions.

Is a site induction a legal requirement?

Yes. While CDM 2015 does not use the exact phrase ‘site induction,’ Regulation 13 requires the principal contractor to provide each worker with suitable site-specific information and instructions before they start work. The approved code of practice (ACOP L153) explicitly states that this should be done through site inductions. The Management of Health and Safety at Work Regulations 1999 also require employers to provide information, instruction, and training to employees. In practice, a site induction is the standard way to meet these legal obligations.

How long should a site induction take?

There is no fixed rule, but most construction site inductions take between 15 and 45 minutes depending on the size and complexity of the project. For a domestic extension with a couple of subcontractors, 15–20 minutes covering the essentials is usually sufficient. For a large commercial site with significant hazards, the induction might take 30–45 minutes and include a site walk-around. The key is to cover everything that person needs to know to work safely on that specific site, without padding it out with irrelevant information.

Do visitors need a site induction?

Yes, but the induction can be shorter and tailored to their visit. Anyone entering a construction site — including clients, architects, building control officers, delivery drivers, and homeowners on domestic projects — needs to be informed about the key hazards and safety rules. A visitor induction typically covers: PPE requirements, areas they must not enter, who they must be accompanied by, and emergency procedures. It does not need to cover tool-specific safety or work methods because visitors should not be doing construction work.

Can I do a site induction verbally or does it need to be written?

The induction itself can be delivered verbally — in fact, a spoken induction with a site walk-around is usually more effective than handing someone a document to read. However, you must keep a written record that the induction took place. This means recording the person’s name, the date, what was covered, and getting their signature to confirm they understood. Without a written record, you have no evidence that the induction happened, which leaves you exposed if the HSE investigates.

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, many principal contractors run a brief refresher every 3–6 months. The key principle is that everyone on site must have current, relevant information about the hazards and procedures.

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.
