Subrogation is the doctrine by which an insurer that has paid an insured’s loss steps into the insured’s shoes to pursue the insured’s claim against the party legally responsible — recovering what it can from the wrongdoer.
Subrogation is one of the foundational doctrines of insurance law. When an insurer pays an insured’s claim, the loss has fallen first on the insurer. But where a third party was actually responsible — a negligent contractor, a careless driver, a defaulting supplier — the law of tort or contract gives the insured a right of recovery. Subrogation transfers that recovery right to the insurer.
The doctrine has two related limbs: the right of subrogation proper (the insurer’s right to pursue the third party in the insured’s name) and the right to recover any sums the insured recovers (so that the insured is not paid twice).
The doctrine is judge-made. The leading authorities include:
Subrogation can also be expressly addressed in the policy wording. Most modern policies contain a subrogation clause expressly granting the insurer the right of subrogation, supplemented by a duty on the insured to assist the insurer in pursuing recovery and to do nothing that would prejudice the right.
Subrogation does not apply to non-indemnity insurance — life and personal accident policies do not give rise to subrogation rights because they are not contracts of indemnity.
For statutory insurance regimes (compulsory motor insurance, employers’ liability), subrogation operates alongside statutory recovery rights. The Compensation Recovery Unit (CRU) regime recovers state benefits paid to PI claimants from defendants and their insurers.
Subrogation arises automatically as a matter of law once the insurer has paid the insured’s loss. The insurer can then bring proceedings in the insured’s name (with the insured’s cooperation) against the third party.
The insured’s duties are typically codified in the policy:
Recovery proceeds typically follow a hierarchy. First, the insurer’s claim payment is recovered from the recovery proceeds. Second, the insured’s uninsured losses (deductible, uninsured heads, costs not covered by the policy) are paid out. Third, any surplus is split as the policy or common law direct.
For complex losses, subrogation pursuits can be highly substantial. A property insurer that has paid a £20m fire loss may pursue the contractor whose negligent welding caused the fire, recovering against the contractor’s PL insurance. The subrogation team manages the litigation in the insured’s name with the insurer’s interests as the primary driver.
For motor insurance, subrogation is industrialised. The ABI/MIB protocols govern most knock-for-knock recoveries between insurers. The Motor Insurers’ Bureau processes recovery from uninsured drivers under the Uninsured Drivers Agreement.
Subrogation can be defeated by certain conduct of the insured. A waiver of subrogation clause in a contract between the insured and a counterparty may extinguish the right; conduct by the insured that compromises the right (settling with the third party, releasing them from liability) may breach the subrogation clause and forfeit cover.
“Pure” subrogation — the equitable doctrine without express policy support.
“Contractual” subrogation — backed by express policy wording, with stronger remedies for breach by the insured.
“Equitable lien” — the insurer’s interest in sums recovered by the insured, allowing the insurer to trace recoveries.
“Joint” or “co-insured” subrogation — restrictions on subrogation against co-insureds under the same policy (the well-established principle that an insurer cannot subrogate against its own insured).
“Subrogation waiver” — express clauses extinguishing the right; explored in a separate entry.
A commercial landlord’s property is damaged by fire caused by a contractor’s negligent hot-work during refurbishment. The property insurer pays the landlord £4.2m for the reinstatement and £1.1m for BI under the landlord’s combined policy. The insurer then subrogates against the contractor in the landlord’s name. The contractor’s PL insurer defends the claim. After negotiation and a JSM, the subrogation claim settles at £3.6m (reflecting some contributory issues identified during disclosure). The landlord cooperates throughout the litigation and gives evidence at the JSM.
The recovery is applied: insurer claim payment £5.3m recovered first; insured’s uninsured losses (deductible £50,000) recovered second; the landlord receives no surplus because the recovery falls short of the full claim payment. The shortfall is absorbed by the property insurer. The reinsurance treaty above the property insurer recovers a proportion of the net loss; the subrogated recovery is treated as a reduction in gross loss for treaty accounting.
