Although the default position is the percentage basis, it may be displaced when shown to operate unfairly. Much has also been said on the cons of the percentage basis, see para 9 of Brook v Reed [2012] 1 WLR 419 (“Brook”). On a careful reading of Brook, one would easily see that there were also criticisms on the time cost basis, see paras 18 and 26: “[18] The aim, if the court is fixing the remuneration, is to reward the value of the services rendered by the office-holder. This does not necessarily equate to time spent, as to which Ferris J said, at p 652: “In my judgment it is vital to recognise three things in this field. First, time spent represents a measure not of the value of the service rendered but of the cost of rendering it. Remuneration should be fixed so as to reward value, not so as to indemnify against cost. Second, time spent is only one of a number of relevant factors, the others being, as I have said, those which find expression in rule 2.47 and similar rules. The giving of proper weight to these factors is an essential part of the process of assessing the value, as distinct from the cost, of what has been done. Third, it follows from the first two points that, as the task is to assess value rather than cost, the tribunal which fixes remuneration needs to be supplied with full information on all the factors which I have mentioned. … [26] As to charging on a time basis, the report states, in para 5.21: ‘The main problem which is perceived to have arisen from the application of the quantum meruit basis in the recent past is that the figure which can be arrived at by the application of current charging rates to recorded hours may be a very large one, not obviously linked to the value of the services rendered. The main remedy for this problem is, of course, the refinement of the concept of ‘value’ and its appraisal, on which some comments are made below.’ There are further observations on the relevance of time spent: ‘6.9 We think we should say something more about the weight which is to be given to time spent … We have a good deal of anxiety about what appears to have become the modern tendency for office-holders to charge mainly, or even solely, by reference to hourly rates. To do so assumes that whatever time was in fact spent on a particular task was necessarily and properly spent by a person of the seniority and experience of the person who actually carried out that task. Although in an ideal world this would be the case, it is foolish to suppose that this ideal is invariably, or perhaps even frequently, achieved. We emphasise strongly the need for the body which fixes the remuneration of an office-holder to take account of all the factors stated in the PL [provisional liquidator] formula. Where the assessment of the other factors indicates that the overall results of the office-holder’s activity are mediocre or disappointing this may cast doubt upon the effectiveness of the time spent.
