Loft Conversions London

What Loft Conversions London does

Loft Conversions London is a privately held London-based construction firm founded in 1999 that specializes in residential loft conversions and related home-extension work. The company designs, manages, and builds four principal conversion typologies — Velux/skylight, dormer, mansard, and hip-to-gable — plus specialized offerings for complex and maisonette loft spaces. Core technical capability spans structural steelwork, dormer construction, partition and insulation fitting, staircase installation, electrical work, and end-to-end handling of building regulations and planning permissions, delivered through a four-step process (site survey, contract and permissions, build, finishing inspection).

The business operates a direct-to-consumer, project-based revenue model with one-time project fees typically ranging from £25,000 to £60,000+, varying by conversion type and property specification. A free no-obligation site survey functions as the primary lead-generation and quoting mechanism, supported by phone (020 71005428), email, website enquiry, and SEO-optimized content marketing. The company also offers Loft Conversion Finance and an adjacent House Renovation Services line (kitchen extensions, basement conversions, full renovations) under a related Renovation London brand, with a stated 10-year workmanship guarantee on completed work.

Customer focus is exclusively on London homeowners — primarily families, period-property owners, and maisonette/leasehold households — seeking additional living space and property-value uplift (claimed 20–25% value add) without relocating. Operating geography is London-only with a Mayfair headquarters (12 Hay Hill, W1J 8NR), no disclosed headcount, no external investors, and no franchise or reseller model.

Others

• Travis Perkins: UK building materials merchant supplying timber, roofing, and construction products to trade and contractor customers. Relevant as a key supplier in the loft conversion value chain rather than a direct competitor.
• Wickes: UK home improvement retailer and installation services provider serving DIY and trade customers. Adjacent competitor in home renovation services with some installation overlap, though primarily a materials retailer rather than a specialist loft contractor.
• Checkatrade: UK trade directory and customer review platform that aggregates local tradespeople including loft conversion specialists. Relevant as a marketing/acquisition channel that shapes competitive dynamics in the fragmented loft conversion market.
