What an HSE Inspector Actually Checks on a Site Visit

What actually happens when an HSE inspector walks onto your site?

Most site managers have a vague sense of dread about HSE visits — but the reality is less mysterious than it feels. Inspectors follow a consistent, logic-driven approach. If you understand what they're looking for, you can manage your site with confidence rather than anxiety. This isn't about passing a test. It's about knowing whether your site is genuinely safe.

Here's what an inspector actually checks, in roughly the order they'll check it.

1. Welfare facilities — first and fast

Inspectors often head to welfare facilities within the first five minutes. It sounds mundane, but it tells them a great deal about site culture. If toilets are filthy, there's no hot water, or there's nowhere to eat that isn't a skip, that signals a management team that doesn't take basic obligations seriously.

Under the Construction (Design and Management) Regulations 2015, the principal contractor must provide adequate welfare from day one of the project — not once the site cabin arrives next week. Inspectors know this, and they'll note it.

What good looks like: Flushing toilets, handwashing with warm water and soap, a heated mess room with somewhere to store and heat food, and facilities that are actually kept clean throughout the working day.

2. Working at height controls

Falls from height remain the single biggest cause of fatal injuries in UK construction. HSE inspectors know this, and it heavily shapes what they look for once they start walking the site.

They'll look for:

• Unprotected edges, voids and roof openings
• Scaffolding that lacks guardrails, toe boards or safe access
• Ladders used where a more stable working platform should be in place
• MEWP operations without adequate ground assessment or trained operators
• Whether workers are actually using the controls that are supposedly in place

That last point matters more than people realise. An inspector can see a perfectly erected scaffold and still issue a notice if nobody is using the gate, or if workers are climbing the outside of it. The physical controls and the behaviour both count.

3. Plant and pedestrian segregation

Wherever plant is moving — excavators, dumpers, telehandlers, delivery vehicles — an inspector will assess whether pedestrians are effectively separated. Struck-by incidents are a persistent cause of site fatalities, and inspectors treat this seriously.

They'll check for marked pedestrian routes, physical barriers, banksman arrangements for reversing vehicles, and whether the site layout makes sense. If the only way from the welfare cabin to the work area cuts through an active vehicle route, that's a problem regardless of what the traffic management plan says.

4. Site documentation — and whether anyone can find it

An inspector will ask to see documents. Typically they'll want:

• The Construction Phase Plan
• Risk assessments relevant to current activities
• Method statements for high-risk tasks underway that day
• Evidence of inductions for workers on site
• F10 notification if required

The key word is relevant. They're not interested in a folder of generic documents that cover everything vaguely. They want to see that the risk assessment for the excavation currently open on site actually reflects that excavation — its depth, the ground conditions, the proximity to services. A document that could have been written for any dig anywhere is a warning sign.

They'll also check whether workers actually know the content of these documents. It's not unusual for an inspector to walk over to a worker and ask what the main hazards of their task are. If the answer is a blank look, the existence of a signed method statement counts for very little.

5. Supervision — are the right people actually present?

This is one of the most underappreciated things inspectors assess. It's not just whether a supervisor exists on paper. It's whether a competent person is visibly present, engaged and enforcing safe working.

An inspector will notice if high-risk work is proceeding without anyone checking it. They'll notice if a supervisor is in the cabin on a laptop while an excavation is open and unattended. Supervision quality is difficult to write into a form, but it's obvious in practice — and so is its absence.

6. Specific high-risk activities in progress that day

Beyond the baseline checks, an inspector will look closely at whatever high-risk work is actually happening during the visit. If there's a confined space entry underway, they'll want to see the permit, the atmospheric monitoring records, the standby arrangements and the rescue plan. If hot works are in progress, they'll check the permit and fire watch arrangements.

This is why it's worth having your documentation organised by task and accessible quickly — not buried in a folder in a van. An inspector who has to wait 20 minutes for you to find the relevant risk assessment is already forming a view.

7. PPE — the last line, not the only line

Inspectors understand the hierarchy of control. If the main response to every hazard on your site is "wear PPE," that's a concern. PPE should be visible as a last-resort layer, not a substitute for eliminating or engineering out the hazard. That said, they will check that appropriate PPE is available, in good condition and being used where required — including RPE for silica or COSHH-relevant tasks.

What triggers a prohibition notice versus an improvement notice?

A prohibition notice stops work immediately. It's issued when an inspector believes there's a risk of serious personal injury — an unguarded roof edge, a live excavation about to collapse, a crane lift with an inadequate plan. Work cannot resume until the notice is complied with.

An improvement notice gives a deadline — usually at least 21 days — to fix something that isn't immediately life-threatening but still breaches health and safety law. Both notices are public record and can inform future prosecutions if things go wrong.

Around 47% of HSE construction inspections result in some form of enforcement action. That's not a scare statistic — it reflects how common it is for sites to have genuine gaps even when managers think they're on top of things.

How to prepare without paper-shuffling for hours

The honest answer is that preparation should be happening continuously, not the night before a possible visit. A site with current, task-specific documents that workers have actually read is more defensible than any last-minute file tidying.

If you're struggling to keep documentation current alongside everything else the job demands, tools like SiteSafePro can help you generate task-specific risk assessments and method statements quickly from a few typed notes or site photos — so what's on file actually reflects what's happening on the ground today, not three weeks ago.

But documentation is the evidence, not the safety itself. The inspector who walks onto your site is ultimately asking one question: is this place actually being managed safely? If the answer is yes, the paperwork should follow naturally.

Quick checklist before any inspection

1. Welfare facilities clean and stocked
2. All edges and voids protected
3. Vehicle and pedestrian routes clearly separated
4. Construction Phase Plan, risk assessments and method statements current and findable
5. Induction records up to date for everyone on site
6. Supervisors present and active on the work face
7. High-risk permits in place and displayed
8. Workers able to describe the hazards of their own task

That's not an exhaustive list — but if you can tick all eight confidently, you're starting from a strong position.
