Mansard loft conversions range from the cheapest installation of £50800 (R L Contracts based in BT36) to the dearest of around £51600 (Browns Joinery based in BT29).
While these estimates give you a good idea how much you'll pay for a mansard loft conversion, the only way to get an accurate price is to get real quotes from real builders.
