The traditional charm of wood, with the modern benefits of uPVC
We're famous for our hybrid uPVC sash windows. Never before seen in this format, we have completely reengineered the way uPVC sash windows are made.
We combine uPVC with a range of internal traditional wood mouldings, including window boards, architraves and even staff beads.
This results in a high performance, low maintenance window with a startlingly traditional look at a more affordable price point to its wooden counterparts.
Our sash windows blend seamlessly into Victorian, Edwardian and other period properties in London, subject to conservation area rules.
Since 1987, we have perfected our uPVC hybrid sash windows to include all the details of traditional wooden sash windows, so it’s incredibly hard to tell the difference.
What do we mean by Hi-Tech Traditional?
We’ve coined the term Hi Tech Traditional, because it explains exactly the type of sash window our customers want.
Watch our team demonstrate how we combine Wood & uPVC to achieve the Hi Tech Traditional window look.
Traditional sash windows, designed and built for modern living.
What are the benefits of double glazed uPVC sash windows?
Low maintenance - uPVC sash windows do not require taking apart and repainting every few years unlike their wooden counterparts. Similarly, they aren’t susceptible to rot and other wood issues.
Traditional look and charm - Our hybrid sash windows preserve the look and charm of your property, all whilst being built for modern living. It’s what we call Hi Tech Traditional.
Energy efficiency- Our double glazed uPVC sash windows come A+ Rated as standard, keeping heat in your home for high efficiency and lower energy bills.
Sound insulation - By eliminating gaps and draughts, our sash windows are designed to reduce external noise for comfortable living.
Security - By fitting steel reinforcing into the frames, our sash windows benefit from added security when compared to other windows on the market.
Trusted by thousands of homeowners throughout London
“There’s nothing that’s not brilliant. The house is warmer. The living room that I used to joke was haunted it was so cold, is now toasty. The windows are all very, very easy to open. We can literally slide them up and down with one finger. None of that wriggling and rattling any more."
Paula, Bellenden Road SE15
"We decided to go with Bespoke Windows because the mid bar on the sash is narrow compared to other companies; the draughting on the windows is white, not grey; and the panelling between the two panes of glass are white not black, so they match the colour of the windows. Definitely happy."
Alex, Streatham Hill SW2

You may book a free home consultation online, by phone or in person at our showroom. We do ask that "all concerned” are at the initial meeting (which could be a Saturday) as there are several choices to make to ensure that your quote is neither under nor over specified. This consultation is carried out in a brief, informative and “non sales” manner.
We would then always invite you to our showroom so that you can see exactly what you would get for your money, believing that any quote is relatively meaningless unless that happens.
When you are ready to place your order, one third deposit is required which can be either transferred online or paid by card at no extra charge.
Your detailed site survey would then be booked and carried out by our Surveyor, Callum, who would also be your project manager, lead you through the entire process, be personally responsible for the outcome and available to answer any questions at any time. Callum has been passionately involved in the window industry for over 40 years!
The fitting would be booked, at your convenience, usually at around ten days notice. On the first day of the fitting, the fitters would arrive usually before 9am, introduce themselves and start by fitting specialist protective coverings to the floor and work area. All Bespoke fitters have decades of experience and have worked solely in the Bespoke team for over ten years. Please see our meet the team video for more details.
Once your job is complete we would issue your final invoice for payment and then your guarantee and FENSA certificates.
