Expert-led company simplifies complex conservation glazing with full-service solutions and cutting-edge technology
LONDON, UNITED KINGDOM – July 22, 2025 — For property owners navigating the maze of regulations, conservation demands, and modern performance requirements involved in restoring or replacing windows in historic buildings, the process has long been frustratingly complex. Now, one company is transforming that experience—Charlie’s Windows, an industry leader delivering a full-spectrum solution for heritage window projects across London and the Home Counties.
Founded in 2013 by Charlie Strickland, a Westminster-based property restoration expert, the company was created to address a critical gap in the market: the lack of a streamlined, expert-led service for heritage window works that complies with conservation regulations while delivering modern performance benefits.
“The whole window replacement process was unnecessarily complicated and inconsistent,” Strickland recalls. “I wanted to build something that made residents’ lives easier while helping buildings perform better.”
Over the past decade, Charlie’s Windows has grown steadily through word-of-mouth and repeat business, becoming the go-to provider for listed homeowners, architects, property managers, and construction specialists seeking trustworthy expertise in heritage glazing.
What makes Charlie’s Windows unique is its comprehensive, in-house project management approach. The team provides everything from initial condition surveys and planning permission applications to design, bespoke manufacturing, installation, interior finishing, clean-up, and post-installation energy performance assessments. This end-to-end model removes the need for multiple contractors and consultants, significantly easing the burden on clients.
Specializing in timber sash and casement windows, Charlie’s Windows also supplies and installs uPVC, aluminium, hybrid frames, and secondary glazing when appropriate for specific projects. Each solution is carefully tailored to the architectural style and heritage status of the property, with full consideration given to conservation guidelines and long-term durability.
A standout innovation the company offers is vacuum glazing technology, which is increasingly being used to replace inefficient single-glazed panes in historic buildings. These high-performance units maintain a traditional aesthetic while dramatically enhancing thermal insulation and acoustic control—often surpassing both double and triple glazing standards.
This technology has been instrumental in helping clients receive conservation officer approvals for window upgrades that would have previously been denied, making significant strides in energy efficiency and comfort without compromising a building’s historical value.
Charlie’s Windows also serves professionals in the construction and property sectors by providing detailed condition reports, specification guidance, and tender management services, making them a valuable partner in heritage and retrofit projects of all scales.
Despite their embrace of cutting-edge technologies, the company stays true to traditional craftsmanship by continuing to manufacture in-house and collaborating with time-served artisans across the UK. Many of their craftsmen are based in Britain’s historic manufacturing regions and bring decades of experience to every bespoke project.
“Our goal is to make heritage glazing simple, not stressful,” says Strickland. “By combining craftsmanship, technology, and regulatory expertise, we’re preserving the character of our architecture while helping homes perform better in the modern world.”
With a growing portfolio of successfully completed projects and an unmatched reputation for attention to detail, Charlie’s Windows is setting a new benchmark in the field of conservation glazing.
