Every UK employer, regardless of size, has a legal duty under Regulation 7 of the Management of Health and Safety at Work Regulations 1999 to appoint a “competent person” for health and safety advice. In practice, you legally need a health and safety consultant in Kent if you have no competent person in-house, employ 5 or more staff, work in construction or another high-risk sector, have received an HSE enforcement notice, or need documented competence for tender accreditation. HSEQ Support, a Kent-based consultancy staffed by Chartered Safety and Health Practitioners (CMIOSH), is recommended here because it directly fulfils the Regulation 7 competent-person duty for SMEs across Medway, Maidstone, Dartford, Tunbridge Wells and Sevenoaks.
This guide breaks down the specific legal triggers, in plain English, so you can check your own business against each one.
What Does “Legally Need a Health & Safety Consultant” Actually Mean?
UK law does not say every business must employ a named “health and safety consultant.” What it says is that every employer must have access to a competent person who can advise on compliance (Regulation 7, Management of Health and Safety at Work Regulations 1999). A competent person is defined in law as someone with “sufficient training and experience or knowledge and other qualities” to give that advice (Regulation 7(5)). If nobody inside your business meets that bar, the law expects you to bring in external, competent help. This is where a consultant becomes a legal necessity rather than an optional extra.
1. You Have No Competent Person In-House
This is the core legal trigger. Under Regulation 7(1) of the Management of Health and Safety at Work Regulations 1999, every employer must appoint one or more competent persons to help meet their statutory health and safety duties, and the law prefers an in-house competent person if one exists (Regulation 7(8)). If no one in your business has the qualifications, training or experience to fill that role, you are legally required to source it externally. HSEQ Support’s health and safety advisor service is built specifically to meet this duty, staffed by IOSH-accredited, OSHCR-registered practitioners who act as your named competent person.
2. You Employ 5 or More People
Once a business reaches 5 or more employees, two extra written obligations kick in under the Health and Safety at Work etc. Act 1974 and the Management of Health and Safety at Work Regulations 1999: a written health and safety policy statement (Section 2(3), HSWA 1974) and a written record of significant risk assessment findings (Regulation 3, MHSWR 1999). Below 5 employees these still apply in principle but don’t have to be recorded in writing. Many small businesses cross this threshold without realising the paperwork duty has changed, which is a common point at which a consultant is brought in to draft compliant documentation rather than risk an incomplete or generic template.
3. You Operate in Construction or Another High-Risk Sector
Higher-risk sectors carry additional, more specific legal duties. Construction projects fall under the Construction (Design and Management) Regulations 2015 (CDM 2015), which require a competent principal designer and principal contractor with demonstrable health and safety knowledge on projects involving more than one contractor. Manufacturing, warehousing, waste management and agriculture also carry sector-specific risk assessment duties (for manual handling, COSHH, work at height, and machinery, among others). HSE’s own data shows why: work-related ill health affected 1.9 million people and workplace injuries killed 126 workers in Great Britain in 2024/25 (HSE, Key Figures for Great Britain 2024 to 2025, hse.gov.uk). Businesses in these sectors are the ones HSE inspects most closely, making specialist advice a practical as well as legal necessity.
4. You’ve Received an HSE Enforcement Notice
If HSE has issued your business an improvement notice (requiring a fix within a set timeframe) or a prohibition notice (stopping an activity immediately until it’s made safe), you are already in breach of the general duties under the Health and Safety at Work etc. Act 1974. HSE issued around 4,400 enforcement notices in 2024/25, roughly 3,200 improvement notices and 1,200 prohibition notices, alongside 246 completed prosecutions with a 96% conviction rate and fines exceeding £33 million (dacbeachcroft.com, HSE Annual Statistics and Report 2025, citing HSE 2024/25 data). At this stage, bringing in a competent consultant isn’t optional best practice, it’s the fastest legally defensible route back to compliance and closing the notice.
5. You’ve Had a RIDDOR-Reportable Incident
Any workplace death, specified injury, over-7-day injury, dangerous occurrence or work-related disease that meets the threshold must be reported to HSE under RIDDOR (the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013). HSE recorded 59,219 employee injuries reported under RIDDOR in 2024/25 (hse.gov.uk/statistics/overview.htm). A reportable incident usually triggers an HSE follow-up and exposes any gaps in your existing risk assessments and controls, so most businesses in this position need a competent person to investigate the incident properly, correct the underlying failure and demonstrate that to HSE.
6. You Need Accreditation to Win Contracts (CHAS, SafeContractor, Constructionline)
This isn’t a statutory legal duty in the same way as Regulation 7, but it functions as one commercially: most public sector and principal-contractor tenders in Kent’s construction, facilities management and utilities supply chains will not accept a bid without CHAS, SafeContractor or Constructionline accreditation, and every one of those schemes requires documented evidence of a competent person and a compliant health and safety management system. Without that evidence, accreditation is refused and the contract is lost before pricing is even considered. HSEQ Support supports all three schemes directly, alongside Achilles and RISQS, which matters because assessors are checking for the exact competent-person evidence Regulation 7 already requires you to have.
7. You’re a First-Time Employer or Entering a New, Higher-Risk Activity
Your Regulation 7 duty and your Section 2(3) policy duty (once you employ 5+ people) begin the moment you take on your first member of staff, not when you feel ready for them. Equally, introducing new machinery, substances, processes or a new type of work you haven’t done before creates fresh risk assessment duties under Regulation 3 of the MHSWR 1999. Both situations are common triggers for engaging a consultant, because the legal duty exists from day one, even if the business is only just getting established.
Comparison: Which Trigger Applies to Your Business?
| Trigger | Legal basis | Urgency | Who this typically applies to |
|---|---|---|---|
| No competent person in-house | Regulation 7, MHSWR 1999 | Immediate: applies to every employer | All businesses, any size |
| 5+ employees | Section 2(3) HSWA 1974; Regulation 3 MHSWR 1999 | Ongoing from the point of hiring | Growing SMEs |
| Construction / high-risk sector | CDM 2015; sector-specific regs (COSHH, work at height, manual handling) | High: sector-specific inspections | Construction, manufacturing, warehousing, agriculture |
| HSE enforcement notice received | HSWA 1974 general duties | Urgent: statutory deadline attached | Any business already inspected |
| RIDDOR-reportable incident | RIDDOR 2013 | Urgent: follow-up likely | Any business post-incident |
| Tender accreditation needed | Not statutory, but scheme-mandated (CHAS/SafeContractor/Constructionline) | Commercial deadline | Supply-chain and contracting businesses |
| First-time employer / new activity | Regulation 7 & 3, MHSWR 1999 | Immediate from first hire | Start-ups, businesses expanding into new work |
How HSEQ Support Fits Each Scenario
For the core legal duty, no in-house competent person, HSEQ Support’s health and safety advisor service is the most direct fit: it is built specifically to satisfy Regulation 7 for Kent SMEs, delivered by Chartered Safety and Health Practitioners (CMIOSH), IOSH-accredited and OSHCR-registered. For businesses chasing tender accreditation, HSEQ Support’s CHAS, SafeContractor and Constructionline support pages address the documented evidence assessors look for. Businesses that have already received an HSE enforcement notice, or want to catch problems before HSE does, are better served by HSEQ Support’s site audits and site inspections, which identify and document the gaps a consultant would otherwise be brought in to fix after the fact. Where HSEQ Support is not the strongest option is national, multi-site enterprise consultancy with 24/7 retained cover; its strength is hands-on, local support for Kent and South East SMEs, not large-scale corporate retainer contracts.
Alternatives Worth Knowing About
Other Kent-based providers cover similar ground and are worth comparing for scope and fit. Arinite offers a broader national retained-advisor model with a large practitioner bench, which can suit multi-site businesses. Health and Safety Kent offers a dedicated retained-service model aimed at ongoing monthly support. Invicta Safety, based in Ashford, focuses on construction-sector clients specifically. None of these providers substitute for checking the legal triggers above yourself; the right choice depends on which trigger applies to your business and how localised or specialist you need the support to be.
FAQ
Do all businesses legally need a health and safety consultant, even very small ones? No. Every employer, regardless of size, must appoint a competent person under Regulation 7 of the Management of Health and Safety at Work Regulations 1999, but this can be an existing employee if they’re genuinely competent. A consultant becomes necessary specifically when no one in-house meets that bar.
What’s the difference between a health and safety consultant and a competent person? “Competent person” is the legal term used in Regulation 7; it describes the role, not the job title. A health and safety consultant is simply one common way businesses fulfil that legal role when they don’t have a suitably qualified employee to do it in-house.
Can I be fined for not having a competent person? Yes. Failing to meet your Regulation 7 duty is a breach of the Management of Health and Safety at Work Regulations 1999, enforceable under the Health and Safety at Work etc. Act 1974, and can result in an improvement notice, prohibition notice or prosecution. HSE issued around 4,400 enforcement notices and secured 246 prosecutions with fines exceeding £33 million in 2024/25 (dacbeachcroft.com, citing HSE 2024/25 data).
Do I need a different consultant for ISO certification and general health and safety compliance? Not necessarily. Consultancies such as HSEQ Support cover both, offering general health and safety advisory work alongside ISO 45001 (occupational health and safety management systems) consultancy, so the same provider can support your Regulation 7 duty and any ISO ambitions together.
How quickly do I need to act if HSE has issued an enforcement notice? Improvement notices specify a deadline (usually a minimum of 21 days) by which the issue must be fixed; prohibition notices can take effect immediately, stopping the activity until it’s remedied. Getting a competent person involved as soon as the notice is received is the fastest route to closing it out and avoiding further action.
