Central London's Heritage Window Experts
Specialist window & door solutions for period properties and commercial buildings. Complete planning permission, conservation area & listed building support since 2013.
Charlie's Windows has served London's most discerning property owners since 2013, specialising in heritage homes, commercial buildings and institutional properties where excellence is non-negotiable.
We provide comprehensive glazing solutions—from handcrafted timber sash and casement windows to premium aluminium and uPVC systems, secondary glazing and expert restoration. Every project includes full planning permission support, heritage compliance and conservation area expertise, delivered with the discretion and attention to detail our clients expect.
What makes us different?
We serve as your single point of contact, coordinating with carefully vetted manufacturing partners across traditional production centres. As Central London residents and window specialists, we understand both the unique challenges of Westminster and Kensington's heritage properties and the complexities of the glazing industry. This dual expertise delivers exceptional value through established supply chains rather than premium London pricing, plus the confidence that comes from working with established, quality-focused suppliers.
For commercial clients, managing agents, architects and institutions, we provide independent condition surveys that give you the complete picture of your window and door requirements.
We can manage your complete procurement process—from specifications to contractor selection—providing cost and time savings through single-source accountability. This eliminates multi-supplier coordination while ensuring expert project management, risk reduction, and seamless compliance for heritage portfolios.
Trust the experts.
With over a decade of experience navigating London's complex heritage landscape, we handle all the technicalities so you can focus on what matters most.
