Project managers & employer’s agents

Professional indemnity for construction project managers and employer’s agents

A client hands you the delivery of their building project — the programme, the budget, the contract and the decisions that keep it on course — and acts on your certificates and advice at every stage. Professional indemnity insurance is the cover that answers when that client, or a party entitled to rely on your work, alleges that your management, your advice or a certificate you signed fell short and left them with a loss.

Part of: Engineering & built-environment PI

In short

Professional indemnity (PI) insurance covers a construction project manager or employer’s agent when a client, or a third party entitled to rely on the work, alleges that a negligent act, error or omission in your professional services — mismanaging the programme, cost or risk, negligent procurement or contractor-selection advice, or a certificate issued without proper care — caused a financial loss, and it funds both the cost of defending the allegation and any damages or settlement you become liable to pay. You manage the delivery of a project on the client’s behalf rather than designing the works, so the standard you are judged against is reasonable skill and care — the competence of a reasonably skilled project manager — not a promise that the scheme will finish to time and to budget, which depend on contractors, ground, weather and decisions outside your control. PI is written on a claims-made basis, so the policy that responds is the one in force when the claim is made or a circumstance is notified — not the one you held when you did the work — which makes the retroactive date and run-off central, because a claim about a project can surface years after it completes. There is no statutory PI minimum for the role; the limit is driven by your appointments and the value of the projects you run, not by a regulator, although firms regulated by the Royal Institution of Chartered Surveyors must meet its minimum policy terms — so it should be set against the most demanding appointment you expect to take rather than a rule of thumb.

Why construction project managers and employer’s agents need professional indemnity

A construction project manager or employer’s agent is engaged to deliver a building project on the client’s behalf — to manage the programme, the cost, the quality and the building contract — rather than to design the works. The client relies on you as their representative: to advise on procurement, to select and manage the contractor and consultant team, to report on progress and spend, to administer the contract, and to certify what is due and when the works are complete. That reliance is the source of the risk, because when a project runs late, costs more than planned or disappoints on delivery, the client looks to the party who was managing it.

Professional indemnity insurance responds to your legal liability for a negligent act, error or omission in those services and — often the larger part — pays the cost of defending the allegation, which is incurred even where a claim ultimately fails. The loss a client pursues is rarely the fee you earned; it is the cost of the consequences, measured against the value of the project rather than the value of your appointment. The table sets out claims typical of the role and how cover responds.

Typical claim against a project manager or employer’s agent	How professional indemnity generally responds
A certificate issued without proper care — over-certifying sums to a contractor who then becomes insolvent, so the employer cannot recover the overpayment	Defends you and meets your liability for the loss flowing from the negligent certification, within the limit and after the excess
Practical completion certified when the works were not in fact complete, releasing retention and starting the defects and limitation clocks early	Responds to the allegation that a certificate within your remit was issued negligently
Mismanagement of the programme, cost plan or project risk that left the client with delay, overrun or abortive cost	Meets your liability where competent management would have avoided or mitigated the loss
Negligent procurement or contractor-selection advice — recommending a route, a form of contract or a contractor that proved unsuitable	Responds where the advice fell below a competent standard and the client acted on it
An extension of time granted without proper assessment, costing the employer liquidated damages it was entitled to recover	Responds to your liability for a negligent decision made in administering the contract
A report, valuation or piece of advice a client, funder or purchaser relied on and acted upon	Reliance on your professional work, where it fell below a competent standard

Across all of these the claim is about how you carried out your professional role — not injury to a person or damage to property, which is why public liability does not answer it. The precise trigger, the definitions and the exclusions differ between wordings, and the limit of indemnity is driven by your appointments rather than by any rule of thumb, so the detail of the policy matters as much as the headline that you are “covered”.

Negligent certification and contract administration

When you act as contract administrator or employer’s agent, you hold the pen on the building contract, and the certificates you issue move money, time and risk between the employer and the contractor. Certification is where a project manager’s exposure is at its sharpest, because a certificate carries real financial consequences the moment it is signed — and a negligent one is a classic, high-value professional indemnity claim.

The duty has an unusual feature. Although the employer engages and pays you, when you certify you are expected to act fairly and impartially between the parties, exercising your own professional judgement rather than simply doing the employer’s bidding. Get that judgement wrong, in either direction, and a claim can follow:

Over-certification. Certifying an interim payment for more than the work properly justifies — for work not done, materials not on site, or defective work — means the employer pays out more than it should. If the contractor later becomes insolvent, the employer cannot recover the overpayment and looks to the certifier for the shortfall. This is among the most common and most costly claims the role attracts.
Wrongful certification of practical completion. Certifying that the works are practically complete when they are not releases part of the retention, ends the contractor’s liability for liquidated damages, and starts the defects liability period and the limitation clock — prejudicing the employer’s position on defects that later emerge.
Extensions of time, loss and expense. Granting an extension of time without a proper assessment relieves the contractor of liquidated damages the employer could otherwise have deducted; mishandling a loss-and-expense claim can expose the employer to cost it did not owe.
Valuations and the final account. Negligent valuation of variations, provisional sums or the final account can leave the employer paying for work it should not have.
Under-certification. Certifying too little, or too late, can give the contractor its own claim — so the exposure runs in both directions.

Because these decisions are made under time pressure, on incomplete information, and in the middle of a live project, contemporaneous records — what you inspected, what you were told and the basis on which you certified — are often what decides whether an allegation of negligent certification succeeds. On a design-and-build scheme the employer’s agent carries the same certifying function while also being the employer’s eyes on whether the contractor’s work meets the employer’s requirements, which concentrates a great deal of reliance in a single appointment.

CDM and Building Safety Act dutyholder roles, and keeping your scope defined

Construction project managers frequently hold, or advise the client on, statutory roles that sit alongside the commercial management of the project — and because those roles carry their own duties, they need to be matched to your appointment and your cover rather than assumed.

CDM 2015 dutyholder roles. The Construction (Design and Management) Regulations 2015 place health-and-safety duties on dutyholders including the client, the principal designer and the principal contractor. A project manager may take on the principal designer role under CDM — coordinating health and safety in the pre-construction phase — or advise the client on appointing and monitoring dutyholders. Where you hold a dutyholder role, a failure to discharge it competently is a professional exposure, and your appointment and your policy should both recognise it.
The Building Safety Act principal designer. The Building Safety Act 2022 introduced a separate principal designer dutyholder — this one concerned with compliance with the Building Regulations, and distinct from the CDM principal designer despite the shared name. A project manager may or may not hold this role. It carries significant duties, particularly on higher-risk buildings, and whether your policy responds to it should be confirmed in writing before you accept an appointment that includes it, because it is not a role every wording contemplates.
Scope creep and the management-or-design line. The role’s defining protection is a clear appointment. A project manager owes a management duty; a designer owes a design duty; and the two carry different risks. When a manager drifts into design — specifying materials, proposing technical solutions, or taking on elements of the design team’s work — the line between management liability and design liability blurs, and you can find yourself answering for a discipline your appointment and your cover did not anticipate. An appointment that defines the role precisely, says what is included and what is excluded, and is not quietly expanded by custom on site, is the single most effective way to keep your liability matched to what you were engaged and insured to do.

The same discipline applies to the parties who can rely on your work. Funders, purchasers and tenants routinely require a direct contractual link to the project manager through collateral warranties or third-party rights under the Contracts (Rights of Third Parties) Act, each of which widens the pool of parties who can bring a claim; a warranty should sit on a “no greater liability” footing and should not promise a higher duty than your appointment. Where several parties contribute to a single loss, a net contribution clause limits your liability to the share fairly yours, rather than leaving you pursued for the whole because you are the party still insured.

Reasonable skill and care, claims-made cover, the retroactive date and run-off

A project manager is not expected to promise a result. Whether a project finishes to time and to budget turns on the contractor’s performance, ground and weather, the supply chain and the client’s own decisions — much of which is outside your control. The standard the law holds you to, and the standard professional indemnity is built to cover, is reasonable skill and care: to manage as a reasonably competent project manager would, judged on what was reasonable at the time and not with hindsight once the outcome is known. An overrun is not, in itself, negligence; a claim succeeds only where you fell below that standard and the client lost as a result.

The trap lies in the words of the appointment. Clients and their advisers sometimes ask a project manager to warrant the outcome — to promise that the works will complete by a fixed date or within a fixed cost, or to accept a fitness-for-purpose obligation — and those are absolute promises, not the reasonable-skill-and-care duty the law would otherwise imply. They are either met or breached however carefully you worked, and standard PI wordings generally exclude them, so a liability you take on by contract can fall outside your cover entirely.

Reasonable skill and care	A warranted outcome
The ordinary professional standard: did you manage the project as a competent project manager would?	An absolute promise: the works will complete to a fixed time, cost or result, full stop.
The standard your PI policy is built to cover.	Routinely excluded by PI wordings — an uninsured liability.
Fault-based: the client must show your management fell short.	Outcome-based: it is enough that the promised date, figure or result was not met.
The right basis for an appointment and any collateral warranty.	To be resisted, capped or removed before you sign.

Construction work also has a long tail. A claim about a certificate, a procurement decision or the management of a project can surface years after completion, when a defect emerges or a building changes hands — and because professional indemnity is written on a claims-made basis, the policy that answers is the one in force when the claim is made or a circumstance is notified, not the one you held when you did the work. Several things follow:

The retroactive date must reach back over your past work. Cover reaches back only to this date, so it should sit at or before your earliest relevant appointment; a later date can leave past projects uninsured, and it should not be reset when you change insurer.
Continuous cover matters. A gap between policies, or letting cover lapse, can strand past work with no policy to respond to a claim about it.
Run-off cover is essential when a practice closes or a principal retires. Because a claim can arrive long after you have stopped trading, ending the policy leaves years of past work exposed; run-off keeps that protection live after you cease — and the extended periods within which certain building-work claims can now be brought under the Building Safety Act make this more important, not less.

There is no statutory PI minimum for the role itself; the limit is driven by your appointments and the value of the projects you run rather than by a regulator. Professional bodies set expectations at the level of principle — the Association for Project Management and the Chartered Institute of Building expect members in practice to carry adequate cover, and firms regulated by the Royal Institution of Chartered Surveyors must meet its minimum policy terms — but the figure you actually need is set by the most demanding appointment you expect to take, not by a rulebook. When you place or renew cover, the Insurance Act 2015 requires a fair presentation of the risk: you must disclose, clearly and accessibly, every material circumstance you know or ought to know — the nature of your appointments, your largest and most complex projects, the certifying and dutyholder roles you take on, and any circumstance that might give rise to a claim — because a fair presentation at placement is what keeps the cover dependable when you come to rely on it.

How Apex places professional indemnity for construction project managers and employer’s agents

A short fact-find, not a 40-question form. We ask about your work as construction project managers and employer’s agents: what you do, who for, fee income, staff, contracts, claims and anything unusual.
A written presentation to insurers. Under the Insurance Act 2015 you have a duty of fair presentation. We help you meet it — and a well-presented risk gets better terms than a bare proposal form.
Quotes set out to compare. Usually three or four, with limits, excesses, retroactive dates, exclusions and premium side by side, and our recommendation in plain English.
No gap in cover. If you are moving from another broker, insurer or scheme, we put the new policy in place before the old one lapses and check the retroactive date protects your past work.
The same person afterwards. Mid-term changes, contract queries, certificates for clients, circumstance notifications and next year’s renewal all go through your named broker.

Why construction project managers and employer’s agents move their PI to Apex

Owned by its directors, not for sale. No consolidator, no private-equity owner, no external shareholders — and we have declined approaches to buy the firm. Read the Apex Independence Charter.
Independent, not tied. No single-insurer scheme, no in-house policy, no placement quotas — the recommendation is the one that fits, not the one we are paid to push.
Over 30 markets, including Lloyd’s. Specialist UK PI insurers and Lloyd’s syndicates via wholesale, so a risk that one underwriter dislikes can still be placed properly with another.
Usually three or four competing quotes, laid out side by side — limit, excess, retroactive date, exclusions and premium — with a plain-language note on the trade-offs.
The stay-put letter. If your existing cover is right, we say so in writing, free and without obligation. How the stay-put letter works.
A named broker all year. The person who places your cover is the person who picks up the phone at renewal, on a mid-term change, or when a letter of claim lands.
Director-level attention on claims. We help you notify circumstances early and in the right form, stay involved once the insurer’s panel solicitors are appointed, and tell you plainly where you stand.
Directly authorised by the FCA since 2016, not an appointed representative trading under someone else’s permissions.

When it is worth getting a second quote

It is worth asking us to re-market your cover when:

You have outgrown a professional-body or adviser-network scheme, or an online-only policy, and nobody has re-marketed your risk in years.
A client, lender, framework or regulator now requires a higher limit, a different basis of cover, or evidence your existing broker cannot produce quickly.
Your insurer has non-renewed, withdrawn from your profession, or imposed an exclusion you were not warned about.
Your renewal rose sharply with no explanation, or the person who knew your firm has left, retired, or been absorbed into a consolidator.
You have a claim, a circumstance, a CCJ or something else non-standard, and your current arrangement treats it as a tick-box decline.
Your broker has been bought by a consolidator or a global broker and the independence you chose them for has gone.

When we are not the right broker

We would rather say so than waste your time. We are probably not for you if:

You want the cheapest possible policy bought online in five minutes with no conversation. An online-only product may suit you better, and we would rather say so than waste your time.
Your regulator or professional body requires you to use one specific scheme with no alternative. That is rare, but where it applies we will tell you.
You are outside the UK, or your firm is effectively a US-domiciled business with a UK office.

Frequently asked

Do construction project managers and employer’s agents legally need professional indemnity insurance?

There is no statute that sets a minimum PI limit for the role itself. In practice the cover is close to unavoidable: client appointments, public frameworks and collateral-warranty requirements almost always call for it, professional bodies such as the Association for Project Management and the Chartered Institute of Building expect members in practice to hold adequate cover, and firms regulated by the Royal Institution of Chartered Surveyors must meet its minimum policy terms. The limit you need is driven by your appointments and the projects you run rather than by a rulebook.

What is negligent certification, and why is it such a serious risk?

When you administer a building contract you issue certificates — for interim payments, extensions of time and practical completion — and each one moves money, time or risk between the employer and the contractor. Negligent certification means issuing one without proper care: over-certifying a payment to a contractor who then becomes insolvent, so the employer cannot recover the overpayment, or certifying completion when the works are not in fact complete. Because the consequences are financial and immediate, and because you are expected to certify fairly and on your own judgement, it is one of the most common and highest-value claims the role attracts — and exactly what professional indemnity is there to answer.

I manage the project, I don’t design it — how can a claim still reach me?

Because you are judged on how you carried out your management role, not on work you never did. If the programme, cost or risk was negligently managed, if your procurement or contractor-selection advice fell below a competent standard, or if a certificate you issued was careless, the client’s loss can be laid at your door even though you designed nothing. The risk is the reliance the client places on you as their representative — and professional indemnity, not public liability, is the cover that answers it.

Does my PI cover the CDM principal designer role and the Building Safety Act principal designer?

Do not assume so. The principal designer under the Construction (Design and Management) Regulations 2015 is a health-and-safety coordination role; the principal designer under the Building Safety Act 2022 is a separate dutyholder concerned with compliance with the Building Regulations, despite sharing the name. Whether your policy responds to either role — particularly the Building Safety Act role on higher-risk buildings — should be confirmed in writing before you accept an appointment that includes it, because not every wording contemplates it.

Does professional indemnity cover a promise to finish the project on time and on budget?

Generally not as an absolute promise. Professional indemnity responds to negligence — management that fell below a competent standard — not to a warranty that the works will complete to a fixed date or cost regardless of how well you managed them. Completion depends on contractors, ground, weather and the client’s own decisions, much of it outside your control, so an appointment that warrants the outcome can take your liability beyond what the policy answers. The safer course is to keep the appointment anchored to reasonable skill and care and to have it read against your wording before you sign.

What does claims-made mean, and why do the retroactive date and run-off matter?

Claims-made means the policy that responds is the one in force when a claim is made against you, or a circumstance is notified — not the one you held when you ran the project. So the retroactive date must reach back to your earliest relevant appointment, or past work is left uninsured, and run-off cover matters when you retire, sell or close the practice, because a claim about a certificate or a decision can surface years after a project completes — a tail the Building Safety Act has lengthened for certain building work.

How much professional indemnity cover do we need?

There is no single figure and no statutory minimum for the role. The limit is driven by your appointments and the value and complexity of the projects you run, the reliance your clients and their funders place on you, and the cost of defending a claim as well as paying it — and whether cover is written on an each-and-every-claim or an aggregate basis can matter as much as the limit itself. Set it against the most demanding appointment you expect to take rather than renewing last year’s figure unexamined, and a specialist broker can help you size it.
