“Pursuant tos.35A Senior Courts Act 1981 , the court has a discretion to award simple interest for such period and at such rate as it thinks fit. Both parties referred me to the approach to determining the amount to award as was summarised by Hamblen J in Carrasco v Johnson[2018] EWCA Civ 87 at [87]: “17. The guidance to be derived from these cases includes the following: (1) Interest is awarded to compensate claimants for being kept out of money which ought to have been paid to them rather than as compensation for damage done or to deprive defendants of profit they may have made from the use of the money. (2) This is a question to be approached broadly. The court will consider the position of persons with the claimants’ general attributes, but will not have regard to claimants’ particular attributes or any special position in which they may have been. (3) In relation to commercial claimants the general presumption will be that they would have borrowed less and so the court will have regard to the rate at which persons with the general attributes of the claimant could have borrowed. This is likely to be a percentage over base rate and may be higher for small businesses than for first class borrowers. (4) In relation to personal injury claimants the general presumption will be that the appropriate rate of interest is the investment rate. (5) Many claimants will not fall clearly into a category of those who would have borrowed or those who would have put money on deposit and a fair rate for them may often fall somewhere between those two rates. “17.

Challinor and Reinhard are examples of cases which were held to fall within that mid-category, justifying a blending between rates, and in both cases interest was awarded at 3% over base rate.”
