“(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.”
