Fitting flexible flue liner, https://www.idostuff.co.uk/sections/Property/Cottage/Flue_liner_cost_choice.html. (note: in the U.K. liner should be installed under LA Building control or by a HEATAS registered installer (from comments received, the top of the liner should be sealed to plate or better still use a pot hanger)). The link has more details and explains the process and costs of a real life job in more detail, covering the points that most suppliers neglect to cover in any sort of useful detail. It might be job you fancy doing yourself?
