Site Inductions: What to Cover and How to Run One

A practical guide to site inductions for UK builders. Why they matter, what you need to cover, how to run one properly, and why digital beats paper every time.

Why site inductions matter

A site induction is not just a box-ticking exercise. It is the first opportunity to make sure everyone on your site knows the risks, understands the rules, and knows what to do if something goes wrong. Done well, it saves lives. Done badly — or not done at all — it leaves you exposed both legally and practically.

It is a legal requirement. Under CDM 2015, every person working on a construction site must receive a site-specific induction before they start work. This applies to all projects, including domestic jobs. The CITB provides training resources to help you run effective inductions. If you are the contractor or principal contractor, the responsibility for providing that induction falls on you.

It keeps workers safe. Every construction site is different. Even experienced workers need to know the specific hazards, access routes, emergency procedures, and welfare arrangements on your particular site. A new joiner who does not know about the fragile roof panel or the live services running under the access road is a serious risk.

It reduces incidents. Research consistently shows that workers are most likely to be injured in the first few days on a new site. A thorough induction addresses this by giving people the information they need before they pick up a tool. It also sets the tone: this is a site where safety is taken seriously, and everyone is expected to play their part.

It protects you. If there is an incident on your site and the HSE investigates, one of the first things they will ask for is evidence that workers received a site-specific induction. If you cannot show that, you are in breach of CDM 2015 and your defence becomes significantly weaker. A signed induction record is one of the most important pieces of evidence you can have.

What must be covered in a site induction

A site induction must be specific to the site. A generic health and safety talk is not enough. Here are the topics you need to cover:

Site rules

The ground rules for working on this site. This covers PPE requirements (what must be worn and where), working hours, site access and parking, designated smoking areas, prohibited areas, noise restrictions, and any client-specific requirements. Keep it practical — workers need to know what is expected of them from the moment they step on site.

Emergency procedures

What to do in an emergency. Cover the fire assembly point and evacuation routes, the procedure for raising the alarm, what to do if there is a gas leak, structural collapse, or other major incident, and the location of fire extinguishers and spill kits. On domestic sites, this can be simpler — but you still need to cover the basics.

Welfare facilities

Where workers can find toilets, washing facilities, drinking water, somewhere to eat and rest, and somewhere to change and store clothing. On domestic projects, you may be using the homeowner’s facilities by agreement — this should be stated clearly in the induction.

Key hazards

The specific hazards that workers need to be aware of on this site. This is not a generic list of construction hazards — it is the particular risks on this particular job. Fragile materials, live services, asbestos, overhead power lines, nearby traffic, unstable ground, shared access with the public — anything that could catch someone out if they are not warned.

First aid arrangements

Who the appointed first aider is (or where the nearest first aid provision is), the location of the first aid kit, and the nearest A&E department. On small domestic sites where there is no designated first aider, you should still cover the basics and make sure everyone knows where the first aid kit is.

PPE requirements

What personal protective equipment is mandatory on site and in which areas. Be specific: hard hat required at all times in the build area, safety boots mandatory, hi-vis vest when near the road, hearing protection when using power tools, dust masks for cutting. Do not assume people will figure it out — tell them.

Running an effective induction

A site induction does not need to be a formal classroom session. On most small building sites, it is a conversation at the start of the day. But there are a few things that make the difference between a useful induction and a waste of everyone’s time.

Keep it short and focused

Nobody wants to sit through a 45-minute PowerPoint before they can start work. Cover the essential information concisely and clearly. For a domestic site, 10–15 minutes is usually enough. For a larger commercial site, 20–30 minutes. If it is taking longer than that, you are probably including too much generic content and not enough site-specific information.

Make it site-specific

This is the single most important thing. Your induction must cover the hazards, rules, and arrangements for this specific site. A generic induction that could apply to any building site in the country is not meeting the CDM requirement. Walk through the site if possible, point out the hazards, show people where things are. A physical walkthrough is worth a thousand slides.

Check understanding

Do not just talk at people and hand them a form to sign. Ask questions. “Where is the fire assembly point?” “What do you do if you find something you think might be asbestos?” “Who is the first aider?” If people cannot answer these basic questions, the induction has not worked, regardless of whether they signed the form.

Record it

Every induction must be recorded. You need to know who received the induction, when, and what was covered. This is your evidence that you met your CDM duty. If the HSE asks for induction records and you do not have them, you are in the same position as if you had not done the induction at all.

Digital vs paper inductions

Traditionally, site inductions have been done on paper. You print out a form, talk through the content, get everyone to sign, and file the forms. It works, but it has some well-known problems.

Paper inductions

Forms get lost in the van or on site
Signatures are illegible or missing
Hard to prove what was covered
Time-consuming to file and retrieve
No easy way to check who has been inducted
Difficult to update if site conditions change

Digital inductions

No lost forms — everything is stored automatically
Workers sign on their phone — clear, timestamped records
Induction content is attached to the sign-off
Instant access to records from anywhere
Compliance dashboard shows who has and has not signed
Easy to update and re-issue when things change

Digital inductions are not just more convenient — they produce a better audit trail. If an inspector asks for your induction records, you can pull them up instantly on your phone. Every sign-off is timestamped, linked to the correct project, and shows exactly what content was covered. No more rummaging through a folder of crumpled forms.

How The Site Book handles inductions

The Site Book takes the pain out of site inductions by auto-creating the induction content from your project data. When you create a project and fill in the details — site address, welfare arrangements, key hazards, emergency procedures — the app automatically builds a site-specific induction document.

Workers sign the induction digitally on their phone. No paper forms, no printing, no chasing signatures at the end of the week. Each sign-off is timestamped and stored against the project, so you always have a complete record of who was inducted and when.

The Compliance Health dashboard tracks induction sign-offs in real time. You can see at a glance who has signed and who has not, so you know before the day starts whether everyone on site has been properly inducted.

If your project details change — new hazards, updated emergency procedures, different welfare arrangements — the induction content updates automatically. You can re-issue the induction and get fresh sign-offs from everyone on site, all through the app.

The induction is also included in your Audit-Ready Pack, so when an inspector asks for evidence of site inductions, everything is compiled and ready to hand over in seconds.

Frequently asked questions

Common questions builders ask about site inductions.

Are site inductions a legal requirement?

Yes. Under CDM 2015, every worker must receive a site-specific induction before they start work on a construction site. This applies to all projects, including domestic work. The induction must cover the specific risks on that particular site — a generic health and safety briefing is not sufficient. The principal contractor (or the only contractor on domestic jobs) is responsible for ensuring that all workers, including subcontractors and their employees, receive an appropriate induction. Failing to provide site inductions is a breach of CDM 2015 and can result in enforcement action from the HSE.

What should be covered in a site induction?

A site induction should cover the key information that workers need to stay safe on that specific site. At a minimum, this includes: the site rules (PPE requirements, working hours, access and parking, prohibited areas), emergency procedures (fire assembly point, evacuation routes, what to do in an emergency), welfare facilities (location of toilets, washing facilities, rest areas, drinking water), key hazards on the site (anything unusual or particularly dangerous that workers need to be aware of), first aid arrangements (who the first aider is, where the first aid kit is, nearest A&E), and reporting procedures (how to report incidents, near misses, or unsafe conditions). The induction should be proportionate to the site — a domestic extension needs a shorter briefing than a large commercial site, but the core topics should always be covered.

How long should a site induction take?

A typical site induction takes between 15 and 30 minutes, depending on the complexity of the site. For a straightforward domestic project, 10–15 minutes may be sufficient to cover the essentials. For a larger commercial site with multiple hazards, restricted areas, and complex emergency procedures, you may need 30 minutes or more. The key is to keep it focused and relevant. Do not pad it out with generic health and safety platitudes that everyone has heard before. Cover the specific risks and rules for this site, check that people understand, and get on with the work. A short, site-specific induction is worth far more than a long, generic one.

Do visitors need a site induction?

Yes. Anyone entering a construction site needs an induction, including visitors, clients, inspectors, delivery drivers who come beyond the site boundary, and anyone else who sets foot in the construction area. The induction for visitors can be shorter and simpler than a full worker induction, but it must cover the essential safety information: PPE requirements, key hazards, emergency procedures, where they can and cannot go, and who to contact if they need help. Visitors should be accompanied on site wherever possible, and their attendance should be recorded. The Site Book makes this straightforward — visitors can receive a brief digital induction and sign off on their phone.
