The cost of a loft conversion in London can vary significantly depending on factors such as the size of the project, the type of loft conversion, and the level of customization required. On average, a basic loft conversion like a Velux (rooflight) conversion may cost between £20,000 and £30,000. Dormer conversions, which add more headroom and floor space, typically range from £35,000 to £55,000. If you’re considering a more complex mansard or hip-to-gable conversion, prices can go up to £60,000 or more.
Keep in mind that these costs can increase based on additional features such as en-suite bathrooms, custom-built furniture, or premium finishes. It’s also important to budget for architect fees, structural calculations, and any planning permission applications if required. To get an accurate estimate, consult with multiple loft conversion specialists in London who can provide a detailed breakdown tailored to your specific needs. A well-planned loft conversion is not only an investment in your home’s value but also a way to enhance your living space and functionality.
