We will pay up to £30 per hour for interpreters. No additional sums will be paid for bookings at short notice, for work done out with normal business hours or under any other special terms and conditions not approved by us.
Interpreters will be paid for the actual time engaged, rounded up to the nearest quarter hour, at £7.50 per quarter hour block.
However if the time engaged is less than one hour, we will pay a minimum charge of one hour for work done at the location of an assignment, court or tribunal; whether you are involved in one or a number of matters.
Examples:
However, if clients A& B are seen at the same location, only the overall time spent can be claimed i.e. 1 hour and 45 minutes with no rounding, which would total £52.50 as opposed to £67.50 when seen at different locations.
These rates apply to civil, criminal, children’s, contempt of court proceedings and advice and assistance cases and all are assessed on the same test as to whether the work was actually, necessarily and reasonably done.
