Factual and Procedural Background
These two appeals arise from road traffic accidents caused by the negligence of two defendants, leading to disputes over the recovery of car hire costs by the claimants while their vehicles were being repaired. The defendants' insurers offered to provide "free" replacement cars to the claimants, but both claimants rejected these offers and instead arranged hire cars through a third party at their own insurers' expense. The defendants contended that the claimants failed to mitigate their losses by rejecting the offers, and thus their claims for hire costs should be reduced or disallowed.
The first claimant, an estate agent, arranged a hire car at £39.90 per day from a hire company after her car was damaged. The negligent defendant's insurer made a cold telephone offer of a replacement car, followed by a letter reiterating the offer. The claimant sought legal advice but received none before the repairs were completed, and claimed hire costs for 71 days. The trial judge awarded only 7 days, reasoning the claimant should have cancelled the hire agreement and accepted the insurer's offer earlier.
The second claimant, a marine consultant, also rejected a similar offer from the negligent defendant's insurer and hired a car at £156.80 per day. The trial judge dismissed his claim on grounds that he ignored the insurer’s offer.
On appeal, HHJ Langan upheld the trial judges' findings that refusal of the "free" replacement car offers amounted to a failure to mitigate loss, rendering the hire costs irrecoverable. The appeals before the current court challenge that conclusion.
Legal Issues Presented
- Whether a claimant who rejects a negligent defendant’s insurer’s offer of a "free" replacement car fails to take reasonable steps to mitigate loss.
- Whether, if the claimant unreasonably rejects such an offer, the claimant’s recoverable loss should be limited to the cost the defendant’s insurer would have incurred for providing the replacement car.
- Whether rejection of a "free" replacement car offer results in the claimant losing all entitlement to damages for loss of use.
- The extent to which the involvement of insurers on both sides affects the assessment of mitigation and recoverable costs.
Arguments of the Parties
Appellant's Arguments
- The claimants argued it was not unreasonable to reject or ignore the defendants' insurers' offers, particularly as the offers did not disclose the true cost to the defendants of providing the replacement cars.
- They submitted that, even if rejection was unreasonable, the claimants should recover the full hire costs incurred, as the defendants had not demonstrated what their own costs would have been.
- The claimants emphasized that their hire agreements with their own insurers allowed them to defer payment and receive credit, making their arrangements effectively "free" and thus comparable to the defendants’ offers.
- They contended that the cold telephone call and threatening tone of the defendants' insurers' letter were inappropriate and likely confusing for ordinary claimants.
Appellee's Arguments
- The defendants relied on the trial judges' factual findings that the claimants acted unreasonably in failing to respond properly to the offers of free replacement cars.
- They argued that since the offers were for free cars, the claimants' losses could have been wholly or mostly avoided, and thus the claims for hire costs were unsustainable.
- They submitted that the cost to the defendants' insurers of providing replacement cars was irrelevant to the claimant's duty to mitigate losses.
- The defendants urged the court to uphold the trial judges' findings of fact and not interfere with their conclusions on mitigation.

Applied to emphasize that mitigation must be assessed objectively considering claimant’s duty to mitigate loss. |

Rejection of defendant’s offer does not deprive claimant of right to substantial damages, only affects costs. |
Supported the proposition that unreasonable refusal of a defendant’s offer does not extinguish damages entitlement but may limit recovery to reasonable costs. |

Court's Reasoning and Analysis
The court began by examining the nature of the defendants' insurers' offers of replacement cars, questioning whether such offers were truly "free" from the claimants' perspective, given that claimants also had arrangements with their own insurers that effectively provided credit or deferred payment. The court noted that the traditional English legal approach excludes insurance considerations from the assessment of rights between parties, focusing instead on the claimant’s personal position.
The court found that it was not unreasonable for the first claimant to await legal advice before cancelling an existing hire agreement to accept the defendants' offer, especially given the absence of clear information about the cost to the defendants of the replacement cars. Similarly, the second claimant’s conduct was not unreasonable as he had passed the insurer’s letter to his own brokers or insurers, and the court rejected the trial judge’s finding that he ignored the offer.
The court emphasized that mitigation must be assessed objectively, considering the combined position of the claimants and their advisers. It held that any offer by a defendant’s insurer must contain sufficient information, including the cost to the defendant, to allow claimants and their representatives to make a reasonable decision. Without this, rejection or ignoring of the offer cannot be deemed unreasonable.
The court rejected the defendants' submission that the cost to their insurers was irrelevant, recognizing that hiring cars is a commercial transaction with profit margins and costs that must be considered when assessing reasonableness of mitigation steps.
Regarding the consequences of unreasonable rejection of a defendant’s offer, the court distinguished between offers in kind and monetary offers, concluding that refusal of an offer to provide a replacement car does not extinguish the claimant’s right to damages. Instead, if rejection is unreasonable, the claimant’s recovery should be limited to the reasonable cost the defendant would have incurred. The court relied on Strutt v Whitnell to support this principle, rejecting the trial judges' view that unreasonable rejection results in no recovery.
Applying these principles to the facts, the court found no evidence that the defendants’ insurers could have provided replacement cars more cheaply than the claimants did or that the claimants’ hire rates were unreasonable. Therefore, it allowed the appeals and ordered judgment for the claimed sums.
Holding and Implications
The court allowed the appeals.
The court held that it is not unreasonable for claimants to reject or ignore a defendant’s insurer’s offer of a replacement car if the offer does not disclose the defendant’s cost, as claimants and their advisers need this information to assess reasonableness. Furthermore, if a claimant unreasonably rejects such an offer, the claimant does not lose entitlement to damages entirely but is limited to recovering the reasonable cost the defendant would have incurred.
The direct effect is that the claimants in these cases recover the full hire costs claimed, as no evidence showed the defendants could have provided cheaper replacement cars. The decision clarifies the application of mitigation principles in loss of use claims involving competing insurer arrangements but does not establish new precedent beyond reaffirming established principles on mitigation and reasonable hire costs.
