PI rectification cost cover: what it covers and where it stops

Category: Insurance definitions · Reviewed by Mark Fox, Broker · Renewals · Last reviewed May 2026

Rectification cost cover in professional indemnity insurance pays for the cost of putting right the professional error itself, rather than only compensating the third party for the consequences of that error. It sits at the intersection of mitigation, civil liability and breach-of-contract wordings, and is one of the most heavily negotiated areas of UK PI cover.

What rectification costs mean in PI insurance

In a standard PI claim, the insurer’s primary obligation is to indemnify the firm against sums it becomes legally liable to pay to a third party — damages, settlements, and associated defence costs. Rectification costs are different. They are the costs of fixing the professional work itself: redrawing the design, reissuing the audit, redrafting the contract, recoding the system. They are the cost of the cure, not the cost of the consequence.

Some UK PI wordings explicitly include rectification costs as a covered head of loss, typically:

Where the cost of rectification is incurred to mitigate a likely claim that would otherwise fall under the policy.
Where the firm’s civil liability extends, by operation of law or contract, to the cost of putting the work right.
Where a specific extension is bought to broaden the cover.

Other wordings exclude rectification costs entirely, or limit them to sums the firm becomes “legally liable” to pay following a third-party demand. The market is not uniform; the schedule and wording must be read carefully.

For context on the related concept of acting before a claim is made, see PI mitigation cost cover.

How rectification cost cover works in practice

Where a wording includes rectification cost cover, several conditions usually apply:

A claim or likely claim must exist. Pure goodwill remediation — fixing a problem the client never complained about — is rarely covered. The wording typically requires that, but for the rectification, a claim would probably be made against the firm under the policy.
The rectification must be reasonable. The insurer will assess whether the chosen course is the least-cost route to disposing of the matter. Replacing a 30-storey façade when a smaller intervention would have sufficed is unlikely to be agreed.
Insurer prior consent is generally required. Spending money before the insurer agrees the proposed approach risks the costs being uninsured. The wording will usually require notification, scoping, and written consent before substantial work begins.
The cost must save the policy money. Some wordings explicitly state that the insurer’s payment for rectification is capped at the saving achieved — i.e. the lesser of the rectification cost or the damages the policy would otherwise have paid.
Defence costs implications. Rectification is often coordinated through the same legal and technical advisers handling the underlying complaint; their costs sit under the defence cost provisions in the usual way.

Rectification costs should not be confused with fees rebates. A fees rebate — the firm refunding fees already invoiced to the client — is treated differently in most wordings and is more commonly addressed under loss of fees cover where bought.

Worked example

Picture a Bristol-based structural engineering practice with a £2m each-and-every limit and a £5,000 excess. The firm designed steelwork connections for a small commercial development. During construction, the contractor identifies a load calculation error that, if left in, would require significant remedial work after handover. The contractor notifies the practice and demands the design is corrected before further fabrication.

The firm faces two paths:

Do nothing pre-emptively. The contractor proceeds, the building is occupied, and three years later the developer brings a claim for £450,000 for remedial works, professional fees, and consequential loss. The PI policy responds in the normal way, paying out within the limit less the excess.
Rectify now. The firm engages with the contractor and re-designs the connections at a cost of £45,000 in additional fees, fabrication waste and site delay attributable to the design.

Under a wording that includes rectification cost cover, the £45,000 (less the excess) may be recoverable, because the cost saves the policy a far larger likely claim. The insurer will want to see scoping, evidence of likely claim, and proportionality of the approach. Without rectification cost cover, the £45,000 falls on the firm regardless of the saving to the policy.

The figures are illustrative; the structural point is the same: rectification cost cover allows pre-emptive action where it saves the policy money, but only where the wording, conditions and consent rules are respected.

When this matters most

Design and engineering professions. Architects, engineers and surveyors regularly face situations where an error can be corrected during construction at a fraction of the cost it would take to fix after completion. Rectification cost cover is particularly valuable in these professions because the saving over a post-completion claim can be large. See sectors / architects.

Software and technology consultancy. Code defects, integration errors and configuration mistakes can sometimes be patched mid-project for far less than the cost of consequential loss the client would otherwise claim. Wordings vary widely on whether software rectification is treated as recoverable; some have specific software-related exclusions or sub-limits.

Audit and tax advisory. Where a professional service has produced a deliverable that contains an error — a tax return, an audit opinion, a valuation — reissuing the deliverable may be cheaper than litigating the consequences. Recovery under PI again depends on the wording, the regulatory context, and whether a likely claim exists.

Common variations and market wording

UK PI wordings phrase rectification cost cover in several ways:

Express rectification cost extension. A defined head of loss with its own sub-limit (often a sub-limit of the policy aggregate). Conditions typically include prior consent, demonstrable claim avoidance, and proportionality.
Civil liability wording absorbing rectification. A broad civil liability extension can pick up rectification where it is part of the legal liability the firm owes the client under the contract or in tort. See civil liability extension.
Mitigation costs only. Where the wording covers mitigation costs but does not separately mention rectification, the insurer may agree rectification spend on a mitigation basis, provided the trigger and consent rules are met. See PI mitigation cost cover.
Specific rectification exclusion. Some wordings exclude the cost of redoing the work, treating it as a business cost the firm should carry as part of normal practice management.
Sub-limits and excess scaling. Where rectification is covered, it commonly carries a sub-limit (for example £100,000 or 10% of the policy limit), and the excess may be applied differently than for indemnity claims.

The interaction with the dishonesty exclusion and the contractual liability carve-outs also matters. Rectification of work done dishonestly is typically excluded. Rectification of work that creates a contractual obligation the firm could not have been compelled to perform absent the contract may also be carved out — see breach of contract cover.

Related concepts

PI mitigation cost cover — pre-claim costs to reduce the size or likelihood of a future claim.
Civil liability extension — broader cover encompassing legal liability however it arises.
Loss of fees cover — recovery of waived or refunded fees.
Breach of contract cover — cover for contractual liability assumed by the firm.
Economic loss claim — pure financial loss claims, which often interact with rectification scope.

Frequently asked questions

Is rectification cost cover standard in UK PI?

It is not uniformly included. Some wordings provide it as a defined extension with a sub-limit and conditions; others restrict cover to sums the firm becomes legally liable to pay to a third party, which excludes pure rectification spend. The schedule should be checked. Where the firm’s profession sees frequent rectification scenarios, the cover is worth confirming explicitly.

What is the difference between rectification costs and mitigation costs?

Rectification specifically pays for putting the professional work right. Mitigation more broadly covers reasonable costs of avoiding or reducing a likely claim, which may or may not include rectification depending on the wording. In practice the two overlap, and some wordings combine them into a single extension.

Do I need insurer consent before incurring rectification costs?

Almost always, yes. Wordings typically require notification of the likely claim, a scope of the proposed rectification, and written consent before substantial cost is incurred. Spending first and asking later can leave the firm uninsured for the cost it has already committed to.

Can I recover the cost of redoing work the client refused to pay for?

Not under rectification cost cover as such. Unpaid fees or write-offs are not rectification costs — they are commercial decisions or fees-related losses. Some wordings provide a separate loss of fees extension; even then, recovery is restricted to specific circumstances. See loss of fees cover.

Is rectification cover subject to a sub-limit?

Frequently, yes. A common structure is a sub-limit of the policy aggregate — for example £100,000 of a £1m policy, or 10% of the limit. Some wordings apply a higher sub-limit where the insurer is satisfied the spend has avoided a materially larger claim. The schedule will set out the sub-limit and any conditions.

Does rectification cover apply where the work is dishonest?

No. Where the underlying conduct was dishonest, fraudulent or in breach of professional regulations, rectification cover is typically excluded along with the rest of the policy. A dishonesty carve-back may protect innocent partners but not the conduct itself. See dishonesty extension.

Does rectification cost cover apply to disciplinary or regulatory matters?

It typically does not. Regulatory investigation and disciplinary defence are handled under separate provisions; see PI investigation cost cover. Rectification is concerned with the underlying professional work and its civil consequences, not with regulatory process.

How does rectification interact with the excess?

The excess is usually applied to the rectification spend in the same way as to indemnity payments, unless the wording explicitly states otherwise. Some wordings apply a single excess to the whole matter — covering both the indemnity claim, if it arises, and the rectification spend on the same facts. The schedule should be read on this point.
