Loft conversion costs typically range from £15,000 to £35,000 depending on the type and complexity. Velux (roof light) conversions are the most affordable at £15,000-£20,000. Dormer conversions range from £20,000-£30,000, while mansard conversions are the most extensive at £30,000-£35,000+. The final cost depends on size, structural work required, bathroom installation, and finishes.

Most loft conversions fall under Permitted Development Rights and don't require planning permission, provided they meet specific criteria (volume allowances, no significant roof alterations, windows don't overlook neighbors). However, planning permission is required for listed buildings, conservation areas, or if Permitted Development Rights have been removed. We assess your property and handle all necessary applications.

A typical loft conversion takes 8-12 weeks from start to finish. Velux conversions are quickest (6-8 weeks), dormer conversions take 8-10 weeks, and mansard conversions require 10-12 weeks. The timeline includes structural work, roofing, insulation, electrics, plumbing (if adding a bathroom), plastering, and final finishes. We provide a detailed project schedule during consultation.

Yes, a well-executed loft conversion typically adds 10-15% to your property value, often exceeding the conversion cost. Adding an extra bedroom with an en-suite can increase value by up to 20%. Loft conversions also improve saleability and are one of the most cost-effective ways to gain extra living space without relocating. ROI is particularly strong in areas where property prices are high and space is at a premium.
