PI claims examples: planning consultants

How to read these scenarios

The scenarios below are generic illustrations of how professional indemnity claims typically arise in this profession. They are composite, hypothetical patterns for explanation only, not descriptions of real cases, clients or firms, and how any actual policy responds always depends on its own terms.

In each case the shape is the same: something goes wrong in the professional work, the client suffers a financial loss, and the consultancy faces a demand. PI insurance typically responds in two ways: it funds the defence, including legal costs and expert input, and it pays damages or a settlement where liability is established, up to the policy limit and subject to the excess and terms.

Scenario 1: a missed submission window

A planning consultancy handling an application misses a submission deadline, and the client loses the chance to secure permission under the policies then in force. By the time the application is made, the policy position has moved against the scheme and the client claims the difference in value and wasted costs.

What went wrong is administrative rather than technical, which is exactly why it is common: diary systems, handovers and holiday cover fail more often than professional judgement. PI responds by defending the claim and meeting the loss if liability sticks. The buying lesson is about limit adequacy: the loss is driven by the value of the client’s scheme, not by the consultancy’s fee, and the limit needs to reflect the schemes you touch.

Scenario 2: a flood-risk misassessment in a report

A consultancy’s report understates flood risk on a site, permission is granted, and the problem emerges later in the development process. The developer claims abortive design costs and the cost of redesign around the true position.

Here the error is technical and may involve reliance on third-party data. The defence often turns on the scope of the appointment and what the report actually promised, which is why PI insurers fund expert-heavy defences in this territory. The lesson: keep the description of your activities on the policy accurate, including specialist assessment work, because work outside the stated activities may not be covered.

Scenario 3: a condition discharge error

A consultancy advises that development can begin, but a pre-commencement condition has not been properly discharged. Works start, the authority intervenes, and the client faces delay, standing costs and in the worst version a fresh application.

Claims like this sit at the junction of process and judgement, and the sums are driven by delay costs on site, which escalate quickly. The buying lesson is again limit adequacy, and also the value of continuous cover: problems on site can surface long after the advice, and it is the policy in force at claim time that responds.

Scenario 4: a heritage assessment that does not survive challenge

A heritage statement supporting an application is challenged, the assessment is found wanting, and a permission is quashed or refused at appeal. The client claims wasted application and appeal costs and the loss of the development opportunity.

Specialist assessment work carries its own standard of care, and consultancies that occasionally step into heritage, ecology or transport territory should make sure the policy knows. The lesson: declare the full range of what you do, including occasional specialisms, and consider whether niche work is better subcontracted to insured specialists.

Scenario 5: negligent viability advice

A consultancy advises on viability in support of a scheme, the numbers prove unsupportable, and the client contends that decisions made in reliance on the advice caused loss when the scheme stalled.

Viability work concentrates reliance: clients make significant financial decisions on the strength of it. Claims often arrive years later, when the scheme fails, which is why the retroactive date and unbroken cover matter so much in this profession. A consultancy that has switched insurer carelessly, or paused cover in a quiet year, can find exactly this claim landing in the gap.

What the patterns teach about buying cover

Three themes run through every scenario. First, limits: planning losses scale with scheme value, not fees, so test your limit against the schemes you advise on, not against last year’s turnover. Second, the retroactive date: planning advice has a long tail, and only continuous claims-made cover with a preserved retroactive date keeps old work insured. Third, accuracy: the policy covers the activities you declared, so the description must match the practice, appeals, expert evidence and specialist assessments included.

Run-off belongs on the list too. When a consultancy closes or merges, claims can still arrive about past schemes, and run-off cover is what keeps a retired principal protected. None of these points costs much to get right at renewal; all of them are expensive to fix after a claim arrives.

Frequently asked questions

Are these real claims against real planning consultancies?

No. They are generic, hypothetical illustrations of common claim patterns in planning work, written to show how PI insurance typically responds. They do not describe any actual case, client or firm, and any real policy’s response depends on its own terms and facts.

What does PI insurance actually pay for in these situations?

Typically two things: the cost of defending the claim, including lawyers and experts, and damages or a settlement where the consultancy is found liable, up to the policy limit and subject to the excess and policy terms. Defence costs alone can be substantial even when a claim fails.

How should a planning consultancy set its limit of indemnity?

Against the value of the schemes and decisions that rely on your advice, not against your fees. Appointment insurance clauses set a floor; the realistic worst-case loss on the work you actually touch should set the working answer, reviewed as instructions grow.

Why does the retroactive date keep coming up?

Because planning claims often surface years after the advice, and a claims-made policy only covers work done after its retroactive date. Continuous cover with a preserved retroactive date is what keeps the long tail of past projects insured.

What if a claim arrives after the consultancy has closed?

A claims-made policy that has simply ended will not respond. Run-off cover continues protection for past work after a practice closes or merges, and planning consultancies winding down should arrange it deliberately rather than letting cover lapse.
