Realistically, the general scale of cost for loft conversions within the city of Leeds can range anywhere from £15,000 - £50,000. However, we have calculated that the average cost for a loft conversion within the city of Leeds is £25,000 from the start of planning to the end of construction. We have calculated that based on averages from all loft conversions completed in the past, making the range vary due to the cost difference between hip to gable loft conversions and mansard conversions. Overall, smaller loft conversions are more common, and because hip to gable and dormer loft conversions are generally cost-effective, the service of a loft conversion becomes increasingly realistic for home owners within the area.
