Log burner installation cost in the UK typically ranges from around £700 to £2,000 for a straightforward fit into an existing chimney opening, rising to £3,500 or more if a new flue liner, twin wall flue system, or fireplace opening work is needed. The final price depends on the type of stove, whether your chimney is already lined, and any building work required to meet clearance and hearth regulations. Getting a HETAS-registered installer to assess your chimney and property first gives you an accurate, tailored cost of a log burner installation rather than a generic estimate.
