The cost of a loft conversion in Southampton typically ranges from £25,000 to £50,000 in 2026, depending on the complexity and size of the project. Basic loft conversions can be more affordable, starting around £20,000, while more extensive projects with dormer windows or en-suite bathrooms can push costs higher.

It’s essential to ensure that your builder is certified, such as being a member of the NICEIC or holding appropriate local council approvals, especially for electrical and plumbing work. These certifications ensure that the work is compliant with safety standards and regulations, providing peace of mind during construction.

Additionally, consider the potential added value to your property; a well-executed loft conversion can increase home value by up to 20% in the Southampton area.
