Subrogation in professional indemnity insurance
Reviewed by Matthew Bartlett, Director, Apex Insurance Brokers Limited · Last reviewed 2026-08-05
Professional indemnity (PI) insurance responds when a client alleges your advice, design or service caused them financial loss. But sometimes the loss was not entirely your doing — a sub-consultant, another firm or a supplier contributed. Subrogation is the mechanism that lets your insurer chase those responsible parties after it has settled with your client.
What subrogation actually means in a PI claim
When your PI insurer pays a claim, it does not simply absorb the cost and walk away. In law, it acquires the right to pursue any recovery rights you personally held against a third party who caused or contributed to that loss. This is subrogation: the insurer is "subrogated" to your position.
A worked example. Suppose you are a firm of surveyors and a client sues you over a negligent valuation. Your insurer settles the claim. If the underlying error actually originated with a specialist sub-consultant you engaged, your insurer can pursue that sub-consultant — using the legal rights you had against them — to recover the sum it paid out. Any money recovered goes back to the insurer, not to you, because you have already been made whole.
Why it exists: the principle of indemnity
Subrogation flows directly from the core purpose of indemnity insurance: to put you back in the financial position you were in before the loss — no worse, and no better. If you could keep both the insurance payout and a separate recovery from the party at fault, you would profit from the loss, which indemnity insurance is designed to prevent.
In English law this is a long-established equitable principle, reinforced by the terms of the policy itself. Most PI wordings contain an express subrogation condition confirming the insurer's right to take over and conduct any recovery action once it has paid or agreed to pay a claim.
How subrogation works, step by step
- A claim is made. Your client alleges loss and pursues you under your PI policy.
- The insurer investigates and pays. It settles the claim or pays a judgment, within your limit of indemnity.
- Recovery rights transfer. On payment, the insurer becomes entitled to any rights you held against a third party who caused the loss.
- Action is brought in your name. The insurer, at its own cost and control, pursues the third party — but legally the claim is brought in your name, not the insurer's.
- Recovery is applied. Money recovered reimburses the insurer up to what it paid. Anything beyond that — for example an uninsured excess you bore — is generally returned to you.
Subrogation compared to related ideas
Subrogation is often confused with contribution and assignment. They are distinct.
| Concept | What it does | Who benefits |
|---|---|---|
| Subrogation | Insurer recovers a paid claim from a responsible third party, in your name | The insurer (up to what it paid) |
| Contribution | Sharing a loss between two or more insurers covering the same risk | The insurers, between themselves |
| Assignment | A deliberate transfer of a legal right or claim to another party | Whoever the right is assigned to |
The key distinction: subrogation is automatic once the insurer indemnifies you, requires no separate transfer document, and never lets the insurer recover more than it actually paid.
What it means for you as the insured
Subrogation places real duties on you, and most PI policies make them express conditions:
- Preserve your rights. Do not settle with, release or waive a claim against a third party without your insurer's consent — doing so can prejudice recovery and, in turn, your own cover.
- Cooperate. Provide documents, correspondence and witness support the insurer reasonably needs to pursue a recovery.
- Watch your contracts. If your appointment or sub-contract terms limit or exclude another party's liability to you, you may have already signed away the rights your insurer would otherwise have used.
- Do nothing to defeat the claim. Actions before or after a loss that destroy a recovery route can amount to a breach of policy condition.
This is why the way you negotiate hold-harmless clauses, net-contribution wording and liability caps with sub-consultants matters — it can quietly determine whether your insurer has anything to recover at all.

Waiver of subrogation
Sometimes a contract requires you to obtain a "waiver of subrogation" — a term under which your insurer agrees, in advance, not to pursue a specified party (often a client or a fellow project team member) even if that party contributed to a loss. Insurers may agree to this, sometimes for an adjusted premium, because it removes a potential recovery route.
If a client contract asks you to arrange a subrogation waiver, tell your broker before you sign. Agreeing to one without your insurer's knowledge can breach your policy and leave you exposed.
Make sure your PI cover and your contract terms actually work together — before a claim tests them.

Does subrogation cost me anything?
No. The insurer funds and controls the recovery action at its own cost. In fact, a successful recovery can help support your claims record. Your obligation is to cooperate and not to prejudice the claim, not to pay for it.
Can my insurer keep any surplus if it recovers more than it paid?
No. Subrogation only allows the insurer to recoup what it actually paid out, plus the costs of recovery in most wordings. Sums recovered beyond that — such as an excess you personally paid — are generally returned to you.
Can I settle directly with a party who contributed to the loss?
Not without your insurer's consent once a claim is in play. Settling or releasing a third party can destroy the insurer's recovery rights and may breach your policy conditions. Always route it through your broker or insurer first.
