The Quick Answer
A health and safety site audit is a structured, on-site review of your workplace against UK health and safety law, your own policies, and (where relevant) standards like ISO 45001 or CDM 2015. It typically runs in four stages: an initial consultation to scope the visit, an on-site review of your premises and working practices, a written report ranking findings by risk, and follow-up support to help you close any gaps. A full management-system audit is usually carried out annually or every six months, while physical inspections of your site happen far more often, daily on high-risk construction sites, weekly in most active workplaces, and at least quarterly if you have a recognised safety representative under the Safety Representatives and Safety Committees Regulations 1977. HSEQ Support, a Kent-based consultancy led by Chartered Members of IOSH (CMIOSH) and registered on the Occupational Safety and Health Consultants Register (OSHCR), carries out both site audits and site inspections across Medway, Maidstone, Dartford, Tunbridge Wells and the wider South East, and offers a free, no-obligation quote to scope the right level of support for your business.
If you have been told your business needs a “health and safety audit,” it is easy to picture something vague: a clipboard, a stern face, a list of things you are doing wrong. In practice it is a lot more useful than that, and a lot more structured. This guide walks through exactly what happens on the day, how it differs from a routine inspection, how often you actually need one, and what it typically costs to get one done properly.
What Is a Health and Safety Site Audit?
A health and safety site audit is a systematic check of how well your business’s health and safety management, not just your physical premises, meets legal requirements and recognised good practice. Where a quick walk-round inspection catches things like a blocked fire exit or a frayed extension lead, a proper audit goes further: it examines your risk assessments, your written policies, your training records, your incident history and how consistently your procedures are actually followed on the ground.
The legal backbone for this sits in the Management of Health and Safety at Work Regulations 1999, which requires every employer to have arrangements in place to plan, organise, control, monitor and review their health and safety measures. An audit is, in effect, the formal “monitor and review” step that regulation expects you to be doing, whether or not you use that exact word for it.
Site Audit vs Site Inspection: What’s the Difference?
The two terms get used interchangeably, but in practice they cover different things and happen on different schedules. Understanding the difference matters because it tells you what to book, and how often.
| Site Audit | Site Inspection | |
|---|---|---|
| What it examines | Your whole health and safety management system: policies, risk assessments, training, records, and how they translate into practice | Physical conditions on site right now: hazards, housekeeping, equipment, PPE use, welfare facilities |
| Typical frequency | Annually, or every six months for higher-risk sectors | Daily to monthly depending on risk level; construction sites are usually checked daily or per shift |
| Who tends to carry it out | An external consultant or a trained internal auditor, working to a documented scope | A site manager, supervisor, or safety representative, often using a checklist |
| Typical output | A written report ranking findings by risk, with a corrective action plan and timescales | A shorter log of hazards found and immediate actions taken |
| Best used for | Proving compliance for tenders, insurers, or accreditation schemes like CHAS and SafeContractor | Catching day-to-day hazards before they cause an incident |
In practice, most businesses need both: regular, lightweight inspections to catch everyday hazards, and a periodic, deeper audit to check the whole system is working and to produce evidence you can show a client, insurer, or accreditation assessor.
What Actually Happens During a Site Audit, Step by Step?
Every reputable provider structures an audit slightly differently, but the shape is broadly the same. HSEQ Support runs its site audits across four stages:
1. Initial consultation. Before anyone sets foot on site, the audit is scoped to your business: what sector you’re in, what standards or accreditations you’re working towards (ISO 45001, CHAS, SafeContractor, Constructionline, RISQS), and any specific concerns you already have.
2. On-site review. A full walk-through of the premises or site, checking safety procedures, physical conditions, risk controls, and how well documented policies match what actually happens day to day. For construction sites this typically covers CDM 2015 compliance, welfare provision, and how site-specific method statements are being followed in practice.
3. Detailed report. A written report setting out findings, usually ranked by risk level, with clear, actionable recommendations and a realistic timescale for addressing each one. This is the document you hand to an accreditation assessor, an insurer, or a nervous client asking for proof you take safety seriously.
4. Ongoing support. A good audit does not end with the report. Follow-up support to help implement the recommendations, and to check they have actually been actioned, is what turns an audit from a one-off box-tick into a genuine improvement in how safely your site operates.
How Often Should You Carry Out Site Audits and Inspections?
There is no single legal number that applies to every business, because the right frequency depends on your risk profile, but there are useful benchmarks:
A full management-system audit is generally recommended annually, or every six months for higher-risk sectors such as construction and manufacturing. If you are certified to ISO 45001, the standard itself requires audits “at planned intervals,” based on the importance of the process being audited and the results of previous audits, rather than a fixed calendar date.
Physical inspections happen much more often. As a rough guide: daily or per-shift checks for high-risk equipment, processes, and changing environments like construction sites; weekly inspections for active work areas in moderate-risk settings; monthly checks for lower-risk areas; and, if your workplace has a recognised trade union safety representative, at least quarterly inspections are a statutory minimum under the Safety Representatives and Safety Committees Regulations 1977.
Why Site Audits Matter in Kent Right Now
Enforcement activity has been rising, not falling. HSE carried out over 13,200 workplace inspections in the 2024/25 reporting year, a sharp increase on the year before, and secured convictions in 96% of completed prosecutions, with fines exceeding £33 million. Where HSE finds a material breach during an inspection, it can recover its costs directly from you under the Fee for Intervention scheme, currently charged at £174 per hour, which typically works out at around £700 for a material breach and £1,500 or more once a formal enforcement notice is issued. That is before you count the cost of any actual incident: across Great Britain, HSE’s most recent figures record 126 workplace fatalities, 59,219 employee injuries reported under RIDDOR, and 40.1 million working days lost to work-related ill health and injury.
None of that is unique to Kent, but it is exactly the kind of exposure a proactive site audit is designed to catch before an inspector, an insurer, or an incident does it for you. For businesses across Medway, Maidstone, Dartford, Tunbridge Wells, Sevenoaks and the wider South East, a local, chartered provider who already knows the area’s construction, logistics and manufacturing base can also scope a more realistic, right-sized audit than a national call-centre operation working from a generic checklist.
Site Audits and Pre-Accreditation: CHAS, SafeContractor, Constructionline and ISO 45001
One of the most common reasons businesses book a site audit is not an HSE inspection at all, it is a client or tender requirement to hold an SSIP accreditation such as CHAS, SafeContractor or Constructionline, or to work towards ISO 45001. A pre-accreditation audit checks your policies, risk assessments and site practices against what the assessor will actually be looking for, so you go into the application with evidence already in place rather than scrambling to produce it after a rejection. If you are still deciding which scheme you actually need, our guide to SafeContractor vs CHAS vs Constructionline breaks down which buyers ask for which scheme.
How Much Does a Health and Safety Site Audit Cost?
Neither HSEQ Support nor most independent consultancies publish a fixed price list for site audits, and that is for a legitimate reason: cost depends on the size of the site, the number of areas or locations being audited, the sector-specific risks involved, and whether you need a one-off audit or an ongoing programme of inspections. A single-site audit for a small office or warehouse will cost meaningfully less than a multi-site construction programme with CDM 2015 duties attached. The only reliable way to know what you will pay is a scoped, fixed-fee quote based on your actual site, which is why HSEQ Support offers a free, no-obligation quote rather than a generic price list that would not reflect your real risk.
Choosing a Site Audit Provider in Kent
Two credentials are worth checking before you book anyone: whether the auditor is a Chartered Member of IOSH (CMIOSH), which signals a recognised, examined level of competence, and whether they are registered on the Occupational Safety and Health Consultants Register (OSHCR), a public register specifically built so businesses can verify a consultant’s credentials before engaging them. HSEQ Support’s team holds both. Being based in Kent, at Unit 5, The Windmill, Ratcliffe Hwy, Hoo, Rochester, also means the audit is carried out by someone who understands the local construction, logistics and manufacturing landscape, not a generic checklist applied from a call centre elsewhere in the country.

Frequently Asked Questions
What is a health and safety inspection? A health and safety inspection is a routine, physical check of a workplace for hazards, such as blocked exits, damaged equipment, poor housekeeping or missing PPE, usually carried out by a site manager, supervisor or safety representative using a checklist. It is narrower and more frequent than a full audit.
How often should health and safety inspections be carried out? It depends on risk level. High-risk environments such as construction sites are typically checked daily or per shift, active moderate-risk workplaces weekly, and lower-risk offices monthly. Where a workplace has a recognised safety representative, quarterly inspections are a statutory minimum under the Safety Representatives and Safety Committees Regulations 1977.
Who is responsible for health and safety inspections? Under the Health and Safety at Work etc. Act 1974, the employer carries overall legal responsibility, though in practice inspections are usually delegated to a site manager, supervisor, or a trained health and safety representative, with more comprehensive audits carried out by an external consultant or a trained internal auditor.
What’s the difference between a health and safety audit and a site inspection? An audit examines your whole management system, policies, training, records and whether they are followed in practice, and typically happens annually or every six months. An inspection is a quicker, more frequent check of physical conditions on site, and can happen daily, weekly or monthly depending on risk.
Do I need a site audit before applying for CHAS or SafeContractor? It is not a legal requirement, but it is one of the most common reasons businesses book one. A pre-accreditation audit checks your policies and site practices against what the assessor will look for, reducing the risk of a rejected or delayed application.
How much does a health and safety site audit cost in Kent? There is no fixed published price, since cost depends on site size, sector risk and scope. HSEQ Support provides a free, no-obligation quote once it understands your specific site and requirements.
