Construction compliance guide
HSE inspections happen without warning. Here is what triggers them, what inspectors look for, what documents you need, and how to make sure you are ready.
HSE inspectors do not turn up at random. Inspections are triggered by specific things, though the result is the same — someone with legal powers arrives on your site and starts asking questions. Here are the most common triggers:
One thing worth knowing: small sites are not exempt. The HSE inspects sites of all sizes. A two-person domestic extension is just as liable to receive a visit as a 50-person commercial project. Do not assume it will never happen to you.
Inspectors are looking for evidence that you are managing health and safety properly. They will check both the physical conditions on site and the paperwork behind them. Here are the key areas:
This is typically the first document an inspector asks for. They want to see that you have a written plan covering how health and safety is being managed on the project. It needs to be site-specific — not a generic template with the project name swapped in.
Risk Assessments and Method Statements for whatever work is happening on site at the time. If someone is working at height, there should be a RAMS for working at height. If there is an excavation, there should be a RAMS for excavation work.
Evidence that everyone on site has been inducted and knows the site rules, emergency procedures, and key risks. Inspectors may also ask to see training certificates — CSCS cards, PASMA, IPAF, or whatever is relevant to the work being done.
Toilets, washing facilities, a rest area, and drinking water. These are legal requirements under CDM 2015 and the Construction (Design and Management) Regulations. On domestic jobs, the homeowner’s facilities can be used by agreement, but there must be something in place.
Scaffolding, edge protection, harnesses, ladder use — inspectors will check that work at height is properly planned, supervised, and carried out using the right equipment. Falls from height remain the biggest killer in construction.
If there are trenches or excavations on site, inspectors will check for adequate shoring or battering, edge protection to prevent falls, and measures to prevent collapse.
Are workers wearing the right PPE for the task? Is it in good condition? Has it been issued and recorded? PPE should be the last line of defence, not the first, but it still needs to be there.
If the project appears to be notifiable (lasting more than 30 working days with more than 20 workers, or exceeding 500 person-days), the inspector will ask whether an F10 has been submitted to the HSE.
The Construction Phase Plan is typically the first document an inspector requests. It tells them how the project is being managed and gives them a framework for the rest of the inspection. If you can hand over a site-specific CPP quickly, you are already making a good impression.
Next, they will ask for RAMS for whatever activity is happening on site at the time. If your lads are on the scaffolding, they want to see the working at height RAMS. If there is a trench open, they want the excavation RAMS.
Then come the induction records. They want to see that every person on site has been inducted and that there is a record of it. A verbal “yeah, I told them the rules” does not cut it — you need a signed record.
If the project appears notifiable, they will ask about the F10. Have you submitted it? Can you show them confirmation?
Here is the key takeaway: if you can produce these documents quickly and they look site-specific, inspectors generally move on. They can see you are on top of things. If you cannot find your paperwork, or what you produce is clearly a generic template with nothing tailored to the job, that is when problems start.
Most inspections follow a similar pattern. The inspector arrives on site — usually unannounced — and identifies themselves by showing their warrant card. They will explain who they are and why they are there.
They will then walk the site, looking at conditions, watching how work is being carried out, and noting anything that concerns them. They may take photographs, measurements, or samples. They have the legal right to do all of this.
Inspectors will talk to workers — not just the site manager or the boss. They want to know whether the people doing the work understand the risks, know the site rules, and have been properly inducted. If a worker says “I have not had an induction” or “I do not know where the first aid kit is,” that tells the inspector more than any document.
They will review your documents — the CPP, RAMS, induction records, and anything else relevant. They may ask to see training certificates, equipment inspection records, or COSHH assessments depending on what work is happening.
Inspectors can enter any workplace without notice during reasonable hours. They can also enter at other times if they believe there is a dangerous situation. You cannot ask them to come back later or arrange a more convenient time.
After an inspection, the outcome depends on what the inspector found. There are five main possibilities, from best to worst:
Everything is satisfactory. The inspector is happy with conditions on site and your documentation. They may give you a verbal ‘well done’ and leave. This is the outcome you want.
The inspector identifies minor issues but does not think formal enforcement is necessary. They will tell you what needs improving and may follow up with a letter. This is not a formal notice and does not go on the public register, but you should act on the advice.
A formal legal notice requiring you to fix a specific issue within a set timeframe — usually 21 days or more. Improvement notices are published on the HSE’s public register. You must comply by the deadline or face prosecution.
Work stops immediately. A prohibition notice is issued when the inspector believes there is a risk of serious personal injury. The activity described in the notice cannot resume until the issue has been resolved. Prohibition notices are also published on the public register.
For serious breaches, the HSE can prosecute. This can result in unlimited fines for companies and fines or imprisonment for individuals. Prosecution is reserved for the most serious cases — but it does happen, including to small firms and sole traders.
The best way to handle an HSE inspection is to be ready before it happens. You cannot predict when an inspector will arrive, so your documentation needs to be in order at all times — not something you scramble to pull together when a warrant card appears at the site gate.
The Site Book lets you create an audit pack — a single PDF containing your Construction Phase Plan, all active RAMS, site induction records, and F10 status. Everything an inspector is likely to ask for, in one document, ready to hand over.
Having this ready means you can give an inspector everything they need within minutes, not hours. That makes a strong first impression. It shows you are organised, you take compliance seriously, and you have nothing to hide. Inspectors see a lot of sites where the paperwork is missing, generic, or obviously written five minutes ago. Being the site where everything is in order and clearly site-specific puts you in the best possible position.
Because The Site Book keeps your documents up to date as the project progresses, you do not need to remember to update things manually. When you add a new RAMS or induct a new worker, it is captured automatically. Your audit pack is always current.
Common questions builders ask about HSE inspections.
No. HSE inspectors have the legal power to enter any workplace at any reasonable time without giving notice. This is set out in the Health and Safety at Work etc. Act 1974, Section 20. Obstructing an inspector is a criminal offence that can result in a fine or imprisonment. If an inspector arrives on your site, let them in, be polite, and cooperate. You can ask to see their warrant card — all HSE inspectors carry one — but you cannot refuse them entry.
There is no fixed schedule. The HSE uses a risk-based approach, which means high-risk sectors like construction receive more attention than lower-risk industries. However, the HSE has limited resources and cannot inspect every site. Some sites will never be visited; others may be inspected multiple times during a single project. Factors that increase the likelihood of an inspection include the size and duration of the project, whether the project is notifiable, whether there have been complaints or incidents, and whether the HSE has intelligence suggesting problems. Small sites are not exempt — the HSE inspects sites of all sizes.
An improvement notice is a formal legal document requiring you to fix a specific issue within a set timeframe — typically 21 days or more. The notice will describe the contravention, explain what the inspector believes you need to do, and set a deadline. You must comply by that deadline. If you do not, you are committing a criminal offence and can be prosecuted. Improvement notices are published on the HSE’s public register, which means anyone — including your clients and competitors — can see them. You can appeal an improvement notice to an employment tribunal within 21 days of it being served, but the appeal does not suspend the notice unless the tribunal orders otherwise.
Yes. You can appeal both improvement notices and prohibition notices to an employment tribunal within 21 days of the notice being served. For an improvement notice, the appeal suspends the notice until the tribunal makes a decision. For a prohibition notice, the appeal does not automatically suspend the notice — work must remain stopped unless the tribunal specifically orders otherwise. Appeals are relatively rare and are only worth pursuing if you have a genuine legal argument that the notice was wrong. If you are considering an appeal, get specialist legal advice promptly, because the 21-day window is strict.
There is no legal requirement to notify your client about a routine HSE inspection. However, if the inspector issues an improvement notice, a prohibition notice, or takes any other formal enforcement action, it is good practice — and often a contractual requirement — to inform your client. Many commercial contracts include clauses requiring you to report any enforcement action or HSE correspondence. On domestic jobs, it is sensible to let the homeowner know if an inspector visited, especially if any issues were raised. Transparency builds trust, and trying to hide enforcement action from a client is likely to cause far more damage than being upfront about it.
