Near Miss Reporting on Construction Sites UK: Legal Duties and How to Do It

What RIDDOR Actually Requires

The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 (RIDDOR) set out what employers must report to the Health and Safety Executive. Near misses sit in a specific category: dangerous occurrences.

A dangerous occurrence is a defined event listed in Schedule 2 of RIDDOR. On construction sites the relevant ones include: the collapse, overturning or failure of a crane or lifting appliance; the collapse or partial collapse of a scaffold more than five metres high; any unintended collapse or partial collapse of a building or structure; and the accidental release of a biological agent likely to cause severe illness.

The list is exhaustive, not illustrative. A near miss that does not match a Schedule 2 event is not a RIDDOR dangerous occurrence. That does not mean it can be ignored. The Management of Health and Safety at Work Regulations 1999 require employers to assess and control risks. A near miss is evidence that a risk has materialised. Failing to record and investigate it is a breach of that duty even without a RIDDOR submission.

RIDDOR records must be kept for at least three years from the date of the event.

What a Near Miss Actually Is

A near miss is an unplanned event that did not result in injury, illness or damage. but could have. A load swinging past a worker's head. A scaffold board kicking out underfoot and caught in time. An excavator reversing towards an unmarked trench edge and stopped just short.

HSE guidance distinguishes near misses from hazard observations. A hazard observation is a static condition. a loose handhold, missing edge protection, a wet surface without warning signs. A near miss involves a sequence of events: something happened, and injury was only avoided by luck or quick reaction.

Both are worth recording. A near miss carries more urgency because it confirms the hazard chain was already active.

The Heinrich Triangle. which posits that for every fatal accident there are 300 near misses at the base. is contested as a precise ratio. The underlying principle is not. Near misses are leading indicators. They predict where the next injury is likely to come from before it arrives.

What a Good Near Miss Record Contains

Photos are valuable. A written description of a scaffold board condition takes fifty words and remains ambiguous. A photo is unambiguous and takes two seconds to capture on site.

Voice notes work well for the narrative section. Speaking a description while still at the location produces better detail than writing it up later from memory. Voice notes must be transcribed and attached to a structured record. a voice note buried in a phone is not a retrievable safety record.

Why Near Misses Go Unreported

HSE surveys show that near miss reporting rates are low relative to the frequency of events. Three causes dominate.

Admin friction. The person who witnessed or was involved in a near miss is on site, working, often in PPE, without easy access to a form or a computer. The mental arithmetic of "stop what I am doing, find the right form, fill it in, hand it to the supervisor" reliably loses to "get on with the job." The longer the gap between event and record, the thinner the detail becomes.

Fear of blame. Workers worry that reporting a near miss will trigger disciplinary action or mark them as careless. This fear persists even in firms that explicitly state they operate a no-blame reporting culture. The only thing that shifts it is visible evidence that reports lead to fixes, not punishment.

Normalisation. On a busy site, near misses accumulate. After a while, experienced workers treat them as ordinary. "That's just how it is" is one of the most reliable predictors of a serious accident waiting to happen.

Reducing friction is the most actionable lever. Culture takes years. A simpler reporting route can be in place this week.

Lower-Friction Reporting in Practice

The standard paper near miss form requires a worker to locate the form, fill it in legibly, and hand it to someone. Each step is a drop-off point.

Dedicated safety apps require an installed app, a login, and familiarity to navigate a form under time pressure. Adoption is variable and lower among subcontract trades.

WhatsApp is already on site workers' phones. Reporting a near miss by sending a voice note and a photo through a structured workflow. one that captures the right fields and routes the record to the office. removes the form entirely. The worker describes what happened while standing at the location. The record is timestamped and visible to the safety manager immediately.

Quickler provides structured WhatsApp workflows for field teams. Workers complete near miss records through a normal WhatsApp chat. No app install. No login required. The office sees results in a dashboard as they arrive, and records export to PDF and CSV for internal review or RIDDOR submissions where applicable.

When You Cannot Produce Records

HSE inspectors can ask to see near miss records as part of a routine inspection or following a notifiable incident. The absence of any records is not neutral. It is evidence that the safety management system is not functioning.

If a serious accident occurs and the investigation reveals a prior near miss that was not recorded or acted on, the employer's liability is materially worse. The near miss was a warning. Not recording it is a failure of the management duty under Regulation 5 of the Management of Health and Safety at Work Regulations 1999.

The standard required is not perfection. It is a functioning system with genuine evidence of use. A stack of near miss reports, most of them acted on and closed out, demonstrates that the system works. Zero reports on a busy site demonstrates the opposite.

Frequently Asked Questions

Is a near miss reportable under RIDDOR?

Most near misses are not reportable under RIDDOR. RIDDOR requires reporting of dangerous occurrences. specific events listed in Schedule 2, such as scaffold collapse or crane overturning. A near miss that does not match a listed dangerous occurrence is not a RIDDOR report, but employers still have a management duty to investigate and record findings.

How long must near miss records be kept?

RIDDOR records must be kept for at least three years. Near miss records that do not reach the RIDDOR threshold have no statutory minimum, but HSE guidance recommends retaining them as part of your health and safety management system. Many firms keep them for the project duration plus three years.

What should a near miss record contain?

Date, time and precise location; a description of what happened; who was involved or nearby; what could have caused injury; immediate action taken; and the name of the person completing the record. Photos and voice notes add useful detail, particularly for complex site conditions.

Why do workers not report near misses?

Three reasons dominate: admin friction. filling in a form after a near miss takes time nobody budgets for; fear of blame; and normalisation on busy sites where near misses feel routine. Reducing friction produces faster results than culture change.
