The special rules which apply to small claims and fast track trial costs do not apply until the claim is allocated to a particular track. Once the claim is allocated to a particular track those special rules apply to the period before as well as after allocation except where the court or a Practice Direction provides otherwise (CPR 46.11). Any costs orders made before a claim is allocated to the small claims or fast track will not be affected by the allocation (CPR 46.13(1)). Where a claim is allocated to one track and subsequently reallocated to a different track then, unless the court orders otherwise, any special rules about costs applying to the first track will apply to the claim up to the date of reallocation, and the rules applying to the second track will apply from the date of reallocation (CPR 46.13(2)).
