The local housing authority may recover costs reasonably incurred by them in taking action—
under regulation 6(1) from the private landlord landlord on whom the remedial notice was served; or
under regulation 10(1) from the private landlord landlord on whom the notice under regulation 10(3) was served.
A demand for recovery of costs under paragraph (1) must be served on the private landlord landlord from whom the local housing authority is seeking recovery.
If no appeal is brought under regulation 9, the costs become payable at the end of the period of 21 days beginning with the day on which the demand is served.
