Do health and safety consultants need professional indemnity insurance?
Reviewed by Matthew Bartlett, Director, Apex Insurance Brokers Limited · Last reviewed 2026-08-05
Health and safety consultants sell judgement. You audit a workplace, write a risk assessment, advise on CDM duties or fire safety, and a client acts on what you told them. If that advice is later alleged to be wrong — and someone suffers loss, injury, or an enforcement notice as a result — the claim lands on you. Professional indemnity insurance exists precisely for that scenario. Below is when it genuinely applies.
Is it a legal requirement?
No UK statute names "health and safety consultant" and orders you to buy PI insurance. Unlike solicitors or accountants, you are not policed by a mandatory-cover regulator. So on a strict reading of the law, it is not compulsory.
That is where the reassurance ends. "Not legally required" is very different from "not needed." The obligation comes from three other directions — a register, your contracts, and the nature of the work itself — and between them they make PI a practical must-have for anyone advising commercially.
When PI is actually needed
1. If you are on (or want to join) OSHCR
The Occupational Safety and Health Consultants Register (OSHCR) is the recognised UK register for general health and safety advisers, set up with backing from bodies including IOSH, IIRSM and others. To register, you must meet criteria that include holding appropriate professional indemnity insurance for the advice you give. If you use OSHCR registration to win work — and many consultants do — PI cover is not optional; it is a condition of being listed.
2. If a client contract requires it
This is the most common trigger. The moment you tender for work with a main contractor, a local authority, an NHS trust, a housing association, a school or any medium-to-large business, the contract or PQQ (pre-qualification questionnaire) will almost always specify a minimum PI limit. Common contractual figures are £1m, £2m or £5m depending on the client and the size of the sites involved. No certificate, no contract — regardless of how good your advice is.
3. If you carry meaningful advice risk (you do)
Even working only for small private clients with no contractual demand, the underlying exposure remains. A health and safety consultant's whole product is professional advice, and PI covers claims that your negligent advice, error or omission caused a client a financial loss. If a risk assessment you produced is later blamed for an incident, or a method statement is challenged after an HSE investigation, defending yourself — let alone paying damages — can be ruinous without cover.

The specific risks PI responds to
Health and safety consulting carries a distinctive claims profile because the consequences of a mistake are often physical, not just financial. Typical allegations a PI policy is designed to meet include:
- Negligent risk assessments — an assessment said to have missed a hazard that later caused an incident.
- Flawed CDM advice — errors when acting as, or advising on, the principal designer role under the Construction (Design and Management) Regulations 2015.
- Fire risk assessment shortcomings — a challenge to an assessment produced under the Regulatory Reform (Fire Safety) Order 2005.
- Defective policies, audits or training — documentation or courses alleged to be inadequate, leading to enforcement action or loss.
- Breach of duty and negligent misstatement — the general claim that a client relied on your professional advice to their detriment.
Because these disputes turn on expert opinion, they are expensive to defend even when you have done nothing wrong. A good PI policy funds that defence, which is often the part consultants value most.
Quick reference: do you need it?
| Your situation | PI needed? |
|---|---|
| Registered with OSHCR | Yes — a registration requirement |
| Contract or PQQ specifies a limit | Yes — no cover, no contract |
| Giving advice to any paying client | Strongly advised — core advice risk |
| Subcontracting to a larger consultancy | Usually — often required by them |
| Purely internal, employed adviser | Employer's cover applies, not personal PI |

The right limit is driven by your contracts, not a guess. If a client demands £2m, you need at least £2m. If you work on large or higher-risk sites, £5m is common. Two points matter as much as the number:
- "Any one claim" vs "aggregate." Cover on an any-one-claim basis reinstates the full limit for each separate claim; an aggregate limit is the total for the whole policy year. Contracts frequently specify which they want.
- Retroactive cover and run-off. PI works on a claims-made basis, so a claim about advice you gave years ago must be met by the policy in force when the claim is made. Keep cover continuous, and arrange run-off cover if you stop trading, or old advice becomes uninsured.
Membership of IOSH or IIRSM signals professionalism but does not, by itself, replace insurance. The insurance and the membership do different jobs.
Common questions
Does OSHCR require professional indemnity insurance?
Yes. Holding appropriate PI cover for the advice you give is part of the criteria for being listed on the register. If you rely on OSHCR to win or keep work, treat PI as mandatory.
I only do small jobs for local businesses — do I still need it?
No law forces you to buy it, but the advice risk is identical whatever the client's size. One disputed risk assessment can generate a claim that dwarfs your fee, so cover is strongly advised for anyone advising commercially.
Is public liability insurance the same thing?
No. Public liability covers injury or property damage caused by your physical activities — for example a visitor tripping over your equipment. Professional indemnity covers loss caused by your advice or professional work. Health and safety consultants typically need both.
