Do you install?

No, as a subsidiary of Deceuninck, the Heritage Window Collection works with a vast range of high performance fabricators and installers throughout the UK and internationally.

Are your windows and doors suitable for conservation areas?

All of the Heritage collection can come in a massive variety of woodgrain foils to make them mimic the appearance of traditional timber windows, and their flush aesthetics can take the aesthetics even further. However, we recommend contacting your local planning officer before installing our products in conservation areas.

What areas do you serve?

We work with fabricators and installers across the country; this means that no matter where you are within the UK, you’re highly likely to find a fabricator near you with ease thanks to our free online tool.

What products are in the Heritage Window Collection?

Our product range includes flush sash windows, flush doors, 2500 chamfered sash windows, 2800 sculptured sash windows, patio doors, and heritage doors. Each of these is available in an unmatched colour range and even hardware accessories and optional glazing styles.

What accreditations do your products have?

Many of our products are rigorously tested to surpass PAS 24 and Secure by Design requirements. When you choose the Heritage Window Collection, you can have peace of mind that they will keep homeowners safe and secure.

What are the benefits of double glazing?

Double glazing is capable of providing much more energy efficiency, as well as improved sound insulation and weather resistance. Our windows are capable of reaching an A+ energy rating thanks to their modern glazing and intelligently designed uPVC frames.

Is triple glazing worth it?

Triple glazing is also available for our products, and it is useful for properties that require the peak of thermal performance. While it can create a heavier unit and be more expensive, it also offers the best in sound insulation, potentially reduced condensation, and incredible energy efficiency.

Yes, we’d be more than happy for you to book a visit to our showroom. It can allow you to see many of our products up close to review their quality before you become an installer or fabricator.


Great windows from a great company, love the range of colours available.

Ezekiel Mendoza

Fantastic and generous customer service from Jen and her team. After our Garden Room supplier let us down by not installing the end caps on our window sills, Jen sourced a closely matching colour and posted them out free of charge. The problem was not Deceuninck’s to solve, yet they did so without hesitation. A breath of fresh air! Thank you!


Great company – good products. Highly recommended.

Dave Singh

Really pleased for the selection of colours for the windows, makes them good for any job
