Consequential loss in PI cover is financial loss that flows as a consequence of a professional error rather than the cost of the error itself. Lost profits, third-party damages payable by the client, additional working capital costs, and disruption losses are all common examples. Whether the loss is covered depends on the policy trigger, the remoteness of the loss in law, and any specific carve-outs in the wording.
What consequential loss means in PI insurance
In professional negligence terms, “consequential loss” is the financial harm that follows from a professional’s error. If a tax adviser misses a relief, the directly recoverable loss is the additional tax. If the client then incurs interest, penalties, professional fees rectifying the position, or loses an investment opportunity, those further losses are consequential.
The phrase is used slightly differently in different contexts:
- In contract, “consequential loss” is often shorthand for the second limb of Hadley v Baxendale [1854] — losses arising from special circumstances within the contemplation of the parties. Many commercial contracts include “consequential or indirect loss” exclusions.
- In tort, the remoteness test under The Wagon Mound [1961] asks whether the loss was reasonably foreseeable. Consequential losses can be recoverable if they pass that foreseeability test.
- In insurance, “consequential loss” can describe either (a) losses flowing from a covered event that the policy expressly responds to, or (b) losses excluded by the policy as being too remote from the primary loss.
For PI insurance purposes, the question is whether the consequential loss being claimed against the firm falls within the civil liability the firm has incurred — and whether the wording carves it out. Most civil liability wordings cover consequential loss without specific limitation, because the trigger is the firm’s legal liability for the loss as established in court or agreed in settlement.
How consequential loss cover works in practice
When a claim arrives, the head of loss claimed often includes both a “direct” component (the immediate financial impact of the error) and a “consequential” component (further losses that the client says it suffered). Both can be the subject of cover if the policy trigger captures them.
Several practical features follow:
- Trigger is civil liability, not the type of loss. Most UK PI wordings respond to “the insured’s civil liability” arising from the professional services. The policy follows the liability — it does not pre-define which heads of loss are allowed. If the law allows the claimant to recover lost profits as consequential damages, the PI policy typically responds.
- Remoteness is a defence, not a cover question. If the claimed consequential loss is too remote (not reasonably foreseeable, or not within the contemplation of the parties), the defendant has a legal defence. The PI policy then funds the defence and indemnifies any reduced settlement.
- Specific exclusions can carve out consequential heads. Some wordings exclude “loss of profit” or “loss of business opportunity” expressly. Others apply sub-limits. These carve-outs typically arise on package policies and cyber-adjacent wordings, less often on bespoke PI.
- Insured’s own lost profits are usually not covered. PI covers what the firm has to pay others; it does not cover the firm’s own lost fees because of distraction, reputational damage, or disruption (unless a specific extension is bought, such as loss of fees cover). See loss of fees cover.
Worked example
Consider a Bristol-based engineering consultancy with £600,000 fee income, £2m each-and-every PI cover and a £10,000 excess. The consultancy designs the ventilation system for a small manufacturing client. Due to a specification error, the system underperforms in summer, causing production to be halted intermittently over a six-month period until a fix is implemented.
The client sues the consultancy for £180,000, made up of:
- £45,000 — rectification cost (a new component and re-commissioning)
- £95,000 — lost gross profit on production during the affected period
- £25,000 — additional labour and overtime costs
- £15,000 — fees of a third-party engineer brought in to validate the fix
The first head is a direct loss — the cost of putting right the defective specification. The remaining three heads are consequential losses flowing from the error. The PI policy covers civil liability arising from the professional services; the legal question is whether each head of loss is recoverable from the consultancy in law.
The lost profit and additional labour costs are within the reasonable contemplation of the parties as foreseeable losses from a faulty ventilation specification for a manufacturing facility. The third-party engineer’s fees were a reasonable mitigation cost. The case settles at £150,000 plus £24,000 defence costs (outside limit). The consultancy pays the £10,000 excess. The policy responds to the full settlement because all the heads of loss were items of the firm’s civil liability under the law of negligence and contract.
The figures are illustrative. The structural point is that “consequential” is a description of the nature of the loss, not a separate trigger — the PI cover follows the civil liability, subject to the wording.
When this matters most
Specification and design work. Engineers, architects and IT consultants whose work product directly affects how a client’s operations function frequently face consequential loss claims because the operational impact of a design error is often larger than the cost of the design correction.
Loss-of-profit claims by clients. Where a professional error causes downstream business interruption — a missed contract deadline because of bad legal advice, a delayed product launch because of a software defect — the client’s lost profit is the dominant head of loss. Whether the consultancy can be made liable for it depends on the contract and remoteness, but if it can, the PI policy follows.
Contracts with consequential-loss exclusions. Many B2B commercial contracts include exclusions for consequential or indirect loss. Where the contract validly excludes consequential loss, the firm’s own legal liability is reduced — which in turn reduces the PI exposure. Reviewing standard client terms with this in mind is part of good risk management.
Common variations and market wording
UK PI wordings address consequential loss in different ways. Look for:
- “Civil liability arising out of the professional services” — the broadest trigger, captures whatever liability the firm is found to have, including consequential heads of loss.
- “Damages and claimant’s costs” definitions — these should be wide enough to include all heads of recoverable loss. Narrow definitions can be problematic.
- “Loss of profit” exclusion — uncommon on bespoke PI, more common on package and combined-cover products. If present, this can materially reduce cover for consequential loss claims.
- “Indirect or consequential loss” exclusion — even less common on standalone PI; if present, it could effectively defeat large parts of a typical PI claim. Read carefully.
- “Liquidated damages” clauses — some wordings exclude liquidated damages, treating them as a contractual penalty rather than a quantified loss. The legal characterisation matters. See breach of contract cover.
The wording governs. Brokers should be able to walk the firm through every cover-affecting wording feature each renewal.

Frequently asked questions
Is consequential loss automatically covered under PI?
Usually, yes — where the wording is a civil liability wording without specific consequential loss exclusions. The PI policy follows the firm’s legal liability. If a court would award lost profits or other consequential damages, the policy typically responds. Specific exclusions can change this, particularly on package products.
What about contract clauses limiting consequential loss?
If a contract validly excludes or limits consequential loss, the claimant cannot recover those heads. That reduces the firm’s exposure — which is good for both firm and insurer. Brokers often welcome well-drafted limitation clauses in client engagement terms. Insurers usually do not require them but appreciate them.
Does the loss have to be foreseeable?
Yes. In tort, loss must be reasonably foreseeable to be recoverable (The Wagon Mound). In contract, loss must arise naturally from the breach or be within the contemplation of the parties at the time of contracting (Hadley v Baxendale). PI policies follow these legal tests because they cover the legal liability, not loss in the abstract.
Are lost profits always covered?
Where the lost profits are the client’s, and the client successfully recovers them from the firm, the PI policy typically responds, subject to the wording. Where the lost profits are the firm’s own (lost fees from existing clients, lost reputation), a standard PI policy does not respond — these require a separate loss-of-fees cover or business interruption cover.
What about liquidated damages?
Liquidated damages are sums agreed in a contract as payable on breach. If they are genuine pre-estimates of loss (or commercially justifiable), they are enforceable. Some PI wordings exclude liquidated damages. Where the firm’s contract liability is liquidated and the wording does not exclude it, the policy generally responds; where it does, recovery may be reduced to the actual loss provable.
Do third-party damages payable by the client count as consequential loss?
Often, yes. If a professional’s error causes the client to incur liability to a third party — for example, an accountant’s failure causing the client to file an inaccurate prospectus and be sued by investors — the client’s liability to the third party is part of its loss. That liability flows from the professional error and is recoverable from the professional. The PI policy follows.
What’s the difference between consequential loss and pure economic loss?
Pure economic loss is the term for financial loss with no underlying physical damage; the contrast is consequential economic loss flowing from physical damage. “Consequential” in the wider sense means loss flowing from an event. The terms overlap and are sometimes used loosely. The cover question is the same: is this loss part of the firm’s civil liability, and does the wording exclude it?
Should I worry about a “consequential loss” exclusion in my PI policy?
Yes. A broad consequential loss exclusion can hollow out a PI policy, because much of the loss in professional negligence claims is consequential in nature. If such an exclusion is present, query its scope with the broker before binding. On bespoke PI it should be removable; on package products it may be a feature of the product.
