Health and safety failures are expensive in every sense — financially, legally, and in human terms, as recent HSE prosecutions have shown all too clearly. For many businesses, particularly SMEs without an in-house safety professional, an external consultant is the practical route to getting this right. But "health and safety consultant" is not a protected title. Anyone can call themselves one, regardless of qualification or competence. Choosing the wrong person can leave you with a false sense of security — and still exposed to enforcement action if something goes wrong.

Here's what to actually look for:

1. Relevant Industry Knowledge

Generic health and safety knowledge only goes so far. A consultant who has spent their career in office-based environments will not necessarily understand the specific risks of construction, manufacturing, warehousing, food production, or healthcare settings.

Ask prospective consultants directly:

• Which sectors have they worked in, and for how long?

• Can they point to case studies or clients in your industry?

• Do they understand the sector-specific regulations that apply to you — CDM 2015 for construction, COSHH for chemical handling, LOLER for lifting equipment, or the specific fire safety requirements for HMOs and commercial premises?

A consultant with genuine sector experience will speak your language, anticipate risks you might not have flagged, and write assessments and procedures that are actually usable on the ground — not generic templates lifted from an unrelated industry.

2. Professional Training and Qualifications

Formal qualifications are the baseline evidence of competence. At minimum, look for:

• NEBOSH (National Examination Board in Occupational Safety and Health) qualifications — the National General Certificate as a starting point, with a NEBOSH Diploma indicating a more advanced, degree-equivalent level of knowledge.

• NVQ Level 5 or 6 in Occupational Health and Safety Practice, which demonstrates applied, workplace-based competence rather than purely theoretical knowledge.

• Sector-specific certifications where relevant — for example, asbestos awareness (P405), fire risk assessment training, or working at height qualifications.

• Degrees either BSc or MSc degrees are an excellent indicator of competence, and most degree programs have prerequisites of entry which usually already meet high levels of competence.

Qualifications alone don't guarantee a good consultant, but their absence should be a significant red flag. Ask to see certificates, not just claims on a website or LinkedIn profile.

3. Professional Body Membership — IOSH

The Institution of Occupational Safety and Health (IOSH) is the largest professional membership body for safety practitioners in the world, and membership grade is one of the clearest signals of a consultant's standing.

Look for consultants who are:

• CMIOSH (Chartered Member) — the gold standard, requiring a combination of qualifications, verified experience, and a professional review process. Chartered status also carries an ongoing obligation to complete Continuing Professional Development (CPD), meaning the consultant's knowledge stays current with changing legislation and best practice.

• CertIOSH or TechIOSH as a minimum, indicating they are working towards or have achieved a recognised professional grade.

IOSH membership isn't just a badge — it means the individual has been independently assessed against defined competence standards and is bound by a professional code of conduct. If someone claims IOSH membership, you can verify this directly via the IOSH website.

4. Specialist Memberships for Specific Services

General safety competence is essential, but many H&S needs call for specialist expertise that sits outside standard generalist training. Two worth specifically asking about:

IIAI — International Institute of Risk and Safety Management / Institute of Investigators, Accident Investigators If you need support with incident or accident investigation — particularly following a serious injury, near-miss, or RIDDOR-reportable event — look for consultants with recognised accident investigation credentials. Membership of a body specialising in investigation methodology (root cause analysis techniques such as ICAM, TapRooT, or similar structured approaches) signals that the consultant won't just produce a surface-level report, but will identify genuine underlying causes and defensible recommendations — something that matters enormously if the incident leads to an HSE investigation or civil claim.

IFSM — Institute of Fire Safety Managers Fire risk assessment is a specialist discipline in its own right, governed by the Regulatory Reform (Fire Safety) Order 2005 (and the Fire Safety Act 2021 and Building Safety Act 2022 in relation to higher-risk buildings). A "competent person" under fire safety law needs specific fire engineering and fire risk assessment knowledge — general H&S training doesn't automatically cover this. IFSM membership, or an equivalent recognised fire safety qualification (such as NEBOSH Fire Certificate or a Level 4/5 Fire Risk Assessment qualification), indicates the consultant has been specifically trained and assessed in this area, rather than treating fire safety as an add-on to a general audit.

If your business operates in higher-risk premises — multi-occupancy buildings, care settings, hospitality, or anywhere with sleeping accommodation — this specialism is not optional.

5. Demonstrable, Verifiable Experience

Qualifications show a consultant can pass an exam; experience shows they can apply that knowledge under real-world pressure. Ask for:

• References from existing or past clients, ideally in your sector.

• Examples (anonymised where necessary) of risk assessments, audits, or investigation reports they've produced.

• Their track record with enforcement bodies — have they supported clients through HSE visits, improvement notices, or prosecutions, and what was the outcome?

Be cautious of consultants who are vague about past work or reluctant to provide references. A confident, experienced consultant will have no issue sharing evidence of their track record.

6. Insurance and Professional Indemnity

A competent consultant should carry professional indemnity insurance. This protects you if their advice turns out to be negligent, and it's also a good proxy for professionalism — insurers generally won't cover practitioners without appropriate qualifications and experience.

7. Ongoing Support, Not Just a One-Off Report

Health and safety isn't a document you file away — it's an ongoing management process. The best consultants offer continuity: periodic reviews, updates when legislation changes, and availability if an incident occurs. Be wary of consultants offering a single generic policy document with no follow-up, as this is unlikely to reflect the realities of your operation over time.

Bringing It Together

When evaluating a consultant, don't rely on a single credential in isolation. The strongest candidates combine:

• Genuine, verifiable experience in your industry

• Recognised qualifications (NEBOSH, NVQ) underpinning their technical knowledge

• Chartered-level IOSH membership, confirming ongoing professional standards and CPD

• Specialist accreditation relevant to the services you need — IIAI-recognised investigation training for accident investigations, IFSM membership or equivalent for fire risk assessment

• A transparent, referenceable track record

• Appropriate insurance

• A commitment to ongoing support rather than a one-off transaction

Health and safety consultancy is ultimately about protecting people, and a poor appointment can leave real gaps in your organisation's risk management — gaps that may only become visible after an incident. Taking the time to properly vet a consultant's credentials, membership status, and sector experience isn't bureaucratic box-ticking; it's the same due diligence you'd apply to any other decision with legal and financial consequences for your business.
