Why London's Most Demanding Clients Choose Charlie's Windows

Deep Heritage Expertise

As Central London residents and window specialists, we understand both the unique challenges of heritage properties and the complexities of the glazing industry. We specialize in heritage compliance and conservation area requirements across London's most challenging listed buildings, from Westminster's Grade I properties near Parliament to Kensington's prestigious garden squares and Chelsea's historic terraces.

Complete Solution Capability

Comprehensive surveys, design, supply, installation and aftercare services with single-point management. From initial assessment to final completion, we handle everything with unmatched expertise across Westminster, Kensington & Chelsea and surrounding boroughs, delivering exceptional value through established supply chains rather than premium London pricing.
