“How does one calculate the additional benefits that Mrs Dimond received by choosing the 1st Automotive package to mitigate the loss caused by the accident to her car? The hiring contract does not distinguish between what is attributable simply to the hire of the car and what is attributable to the other benefits. But I do not think that a court can ignore the fact that, one way or another, the other benefits have to be paid for. 1st Automotive have to bear the irrecoverable costs of conducting the claim, providing credit to the hirers, paying commission to brokers, checking that the accident was not the hirer's fault and so on. A charge for all of this is built into the hire. How does one estimate the value of these additional benefits that Mrs Dimond obtains? It seems to me that prima facie their value is represented by the difference between what she was willing to pay 1st Automotive and what she would have been willing to pay an ordinary car hire company for the use of a car. As the judge said, 1st Automotive charged more because they offered more. The difference represents the value of the additional services which they provided. I quite accept that a determination of the value of the benefits which must be brought into account will depend upon the facts of each case. But the principle to be applied is that in the British Westinghouse case[1912] AC 673 and this seems to me to lead to the conclusion that in the case of a hiring from an accident hire company, the equivalent spot rate will ordinarily be the net loss after allowance has been made for the additional benefits which the accident hire company has provided.”
“One is that preferred by Judge LJ in the Court of Appeal. The excess cost was not reasonably incurred as the cost of hiring the substitute car. Mrs Dimond's right of recovery is limited to the reasonable cost, that is to say the lesser sum. Another way of looking at the matter is to say, as does my noble and learned friend, that, if the whole cost is to be brought into account, then the benefits must be brought into account as well. This raises the question discussed in British Westinghouse Electric and Manufacturing Co Ltd v Underground Electric Railways Co of London Ltd[1912] AC 673 and the distinction between what is and is not collateral.”
“40. The third possible method and the one preferred by this court in Burdis at [139] is to look at “…actual locally available figures”
“73. …To summarise, the questions are: (i) did the claimant need to hire a replacement car at all; if so, (ii) was it reasonable, in all the circumstances, to hire the particular type of car actually hired at the rate agreed; if it was, (iii) was the claimant “impecunious”; if not (iv) has the defendant proved a difference between the credit hire rate actually paid for the car hired and what, in the same broad geographical area, would have been the BHR for the model of car actually hired and if so what is it; if so, (v) what is the difference between the credit hire rate and the BHR?”
“… the search must be for the figure which the claimant was willing to pay [to use Lord Hoffmann’s formulation] on the basis that he had in fact gone into the ordinary car hire market to find a temporary replacement for his vehicle. In doing that the evidence of a claimant that he would be disinclined to spend more than necessary on a car would be relevant. There might be evidence of how the claimant has sourced hire cars in different contexts. Some might be fortunate to have access to discounted rates through membership of motoring or professional bodies. As was recognised in Burdis a claimant hiring a vehicle to replace one damaged by a tortfeasor would be under a duty to take reasonable steps to mitigate his loss. That does not mean that a claimant would be expected to telephone every last car hire provider in the locality to seek details of various deals that might be available. But the reality today is that almost anybody seeking to hire a vehicle in any particular locality would be likely to investigate the market by doing a simple comparative search on the internet. The full panoply of different hire rates available to the credit hire industry through specialist websites (and regularly produced in credit hire litigation) would not be available to an ordinary driver, but one way or another it is not difficult for anyone wishing to hire a car to discover the rates offered by the major hire companies. Cheapest is not necessarily best and for all sorts of reasons anyone may reasonably choose to hire from a company that is not the cheapest available.”
“30. Questioning of the claimant on this issue, should be directed to exploring what he would have been willing to pay on the hypothesis that he would have gone into the market to hire a vehicle. ”
“… Had the judge been reminded that the averaging exercise in which he had engaged was disapproved by authority, he would have had a range of Basic Hire Rates to choose from which covered a spectrum from£10.00 per day less than the figure on which he alighted to£7.00 per day more. The correct approach to reflect the factors that the evidence disclosed in this case would have been likely to lead the judge to pick a figure somewhere in the middle, in fact a little less than the average upon which he eventually chose. Whilst able to hire a vehicle in the market, the claimant was not especially affluent and had demonstrated by his evidence his disinclination to spend more than was necessary. Had he hired, he would have done so with a nil excess from a major reputable company with a local presence. The error in approach has not resulted in any detriment to the claimant.”
