Timber Casement Windows London
let light in and retain heat, built to last.
Ayrton’s casement bays are something rather special. More often than not, we accurately copy the original windows, faithfully recreating stained glass, the right curves and lead detail all within the original frame dimensions. Your new window will be brand-new, warm and secure, but it’ll retain that quintessential period look for your period property. And when it’s time to fit, the window is mechanically lifted into place. It’s the best – and most beautiful – option to protect your windows long-term against the British rain and shine.

We can design and create English casement bays and windows to your original specifications, or help you come up with a brand-new design. All our casement windows come fully finished, and our bay casement windows are made in one piece to provide the ultimate protection against the Great British weather.
We know that listed buildings and homes in certain conservation areas require any new windows to match the original design and materials of the existing ones. We are the experts when it comes to bespoke windows for heritage homes – not only can we create windows that conform to planning regulations, we can also help you with the design and application process, too.
Our expert sales team is here to assist with your project. Need an initial estimate? Looking for guidance on your next steps? Want to see our products firsthand? We’re ready to help and show you around our friendly showrooms.
We prefer to conduct a site visit whenever possible to provide thorough and professional advice, covering all London postcodes and beyond. During a visit, our sales team will discuss the scope of work with you and explain Ayrton’s approach, including details about the materials we use, our fitting methods, our factory and business operations. The more questions you have for us the better! We take initial measurements to prepare a precise quotation for you.
If you haven’t already visited one of our showrooms, we encourage you to do so while you consider your quote. Our showrooms are useful spaces to explore our product range and get a feel for what you are investing in. Alternatively, our sales team can share locations of local Ayrton installations for you to inspect, or you can speak directly with one of our clients to hear firsthand about their Ayrton experience.
Following a deposit paid, our work starts with a detailed survey of your property to ensure we design with precision and your windows (or doors) are built to fit their apertures. Once design is agreed, production begins at our factory and our Operations team with an estimated fitting date.
Making your brand-new window or door is only part of the job. Ensuring that the product is fitted precisely and securely is important. All our fitters are Ayrton employees, and it’s their job to make sure that they get that perfect fit with minimum fuss.
Casement windows are hinged windows that open outward (mostly), typically using a handle or stay that’s also used to lock the window when closed. Like sash windows, casement windows have been a popular style in the UK for several hundred years, particularly in Tudor homes and cottage-style properties.
We design and craft a broad range of casement window styles, including top, side, and bottom-hung configurations, inward- or outward-opening, flush or raised, and more. Whether looking for timber casement window replicas that are indistinguishable from the originals for a period home, a sleek and flush design for a contemporary home, or have other bespoke window needs, speak to Ayrton Bespoke first.
Timber casement windows are easy to clean and require minimal maintenance over their expected service life of 60+ years. Swinging open, they typically provide access to each glass pane for convenient cleaning, and modern, durable surface finishes mean only having to check the paintwork after several years of ownership. Our internal components are manufactured using superior-grade materials and tight tolerances for decades of smooth, maintenance-free operation.
With nothing more than a new paint job every couple of decades and routine cleaning, your bespoke timber casement windows should stay beautiful and in perfect working order for a lifetime.
We are London’s leading experts when it comes to crafting true replicas of existing casement windows for period or conservation area homes. Our team accurately recreates casement windows that bring modern thermal efficiency, security, and performance to traditional homes while keeping their distinct look, feel, and character intact. Bringing decades of experience in renovating period properties to the table, our team also understands how to navigate planning permissions and building regulations, ensuring an on-time and in-budget project.

Casement windows designed with security in mind are as secure as any other type of window. At Ayrton, all our casement windows are fitted with insurance-approved and high-security locks, while our frames feature high-quality ironmongery from ‘The Anvil’ and multi-point locking for additional security. Ayrton Bespoke is FENSA-accredited and we hold the BSI Kitemark for window and door installations, giving you peace of mind that your high-security windows are securely installed.
Our experienced in-house installation team typically takes about a day to install a complete set of casement windows—including time spent ‘making good’ or repairing any plaster damage. In cases where we fit large casement bay window and require HIAB cranes and scaffolding, installation may take up to 3 days.The entire process from first contact to final quality checks typically takes around 14 to 16 weeks.
Our casement windows aren’t off-the-shelf; they’re custom designed and handcrafted using a combination of traditional woodworking techniques and modern manufacturing processes.
Bespoke timber casement windows may vary significantly in cost. Factors such as the size, design complexity, specialised ironmongery or stained glass work, and glazing options may all affect the final cost.
At Ayrton Bespoke, we offer a free at-home consultation service, allowing us to fully understand your needs before delivering a custom quote based on your unique requirements.
A window’s energy efficiency largely depends on the quality of the glazed unit; however, factors such as manufacturing tolerances and the quality of the installation will also play a role. All Ayrton Bespoke casement windows are fitted with high-efficiency double-glazed units with a U-value of around 1.2 W/m²K as standard, meaning enhanced insulation and lower heating and energy bills.
Where thermal efficiency is a genuine priority, our team may fit vacuum-sealed glazed units with a U-value as low as 0.7 W/m²K—significantly outperforming even the best inert-gas double-glazed windows.
