Recovery of interestU.K.
14.—(1) If the Secretary of State decides to recover any amount under regulation 11 or 12, she may also recover on demand interest on that amount for the period beginning with the day following that on which the amount was paid and ending on the day on which she recovers it.
(2) The rate at which the interest is payable for any day in that period is one percentage point above LIBOR.
(3) For the purposes of paragraph (2) “LIBOR” means the sterling three month London interbank offered rate in force on the day in question, and in any proceedings relating to the recovery of such interest a certificate of the Secretary of State stating the LIBOR applicable for any day is conclusive evidence of the rate applicable for that day if the certificate also states that the Bank of England notified the Secretary of State of that rate.
