“(4) Subject to paragraph (7), where paragraph (1)(b) applies, the court must, unless it considers it unjust to do so, order that the claimant is entitled to – (a) interest on the whole or part of any sum of money (excluding interest) awarded, at a rate not exceeding 10% above base rate for some or all of the period starting with the date on which the relevant period expired; (b) costs (including any recoverable pre-action costs) on the indemnity basis from the date on which the relevant period expired; (c) interest on those costs at a rate not exceeding 10% above base rate; and (d) provided that the case has been decided and there has not been a previous order under this sub-paragraph, an additional amount, which shall not exceed£75,000 , calculated by applying the prescribed percentage set out below to an amount which is – (i) the sum awarded to the claimant by the court; or (ii) where there is no monetary award, the sum awarded to the claimant by the court in respect of costs – [prescribed percentages are set out]” [prescribed percentages are set out]”
“The words “provided that the case has been decided and there has not been a previous order under this sub-paragraph” at the beginning of r.36.17(4)(d) were introduced with effect from6 April 2015 when Pt 36 was re-enacted …. A case is “decided” when all the issues in the case have been determined, whether at one or more trials (r.36.3(e)). This amendment is designed to ensure that in a given case there should be only one “additional payment” even though several successful claimant’s Part 36 offers relevant to different issues may have been made.”
