Trending now: on-trend colours for uPVC sliding sash windows in 2026

The external impact new windows have is just as impressive, perhaps even more so. New windows can seriously upgrade your kerb appeal, so picking the right colour is important.

Why window colour matters more than ever in 2026

Advances in manufacturing have moved us far beyond the era of plain white uPVC, and homeowners are now placing just as much importance on style as they are on energy performance. The colour of a window can influence kerb appeal, add a cohesive interior design scheme and can even play a part in boosting property value. With more people choosing custom finishes over standard white, colour has become a key factor in creating homes that feel both personalised and future ready.

Top uPVC sliding sash window colours dominating 2026

Warmer, earthy tones are on their way to replace the popular greys of previous years. Homeowners are choosing rich browns and greens for their windows, bringing depth, warmth, and character to both modern and traditional houses.

Brown or green not your style? Not a problem. Today’s sash windows come in a whole spectrum of finishes, and you can explore designs that balance energy efficiency and traditional charm with leading UK suppliers like Quickslide.

How to choose the right colour for your home style

There’s plenty to consider when it comes to choosing your new window finish. A key place to start is the type of home you live in, whether it’s a modern new build or a period property. uPVC sash windows in particular look appealing in both modern and traditional homes, no matter which colour you choose.

It’s up to you whether to complement or contrast against the material of your home. Some homeowners opt for darker finishes like black or anthracite grey to sharply contrast against lighter exterior walls, while many prefer softer, more natural tones that blend in with brick, stone or render. Choosing a finish that either stands out or settles in can completely change the overall character of your property, so it’s worth considering the look you want to achieve before deciding.

Will these colours still look good in 10+ years?

It’s important to balance trends and timelessness. New windows are a long term investment, often lasting decades, so it’s important to choose a colour you’ll still like in 10 years’ time. Modern uPVC sliding sash windows typically come with a manufacturing guarantee of up to 10 years, but with simple regular maintenance, they can last much longer.

Personalisation made easy: dual colours & matching accessories

Choosing the perfect windows that match with both the exterior and interior of your home can be difficult. For some homeowners, the best option is to opt for a dual colour finish, with different colours on the inside and outside. Many manufacturers can offer this style, with a bold colour like anthracite grey on the outside and a more neutral smooth white or white grain internally.

There’s also plenty of customisable hardware options available for sash windows. Choose between modern or heritage styles, and pick from a range of finishes to match your home design.

Quick tips to avoid common colour-choosing mistakes

New windows are a big investment, and they could be in your home for decades to come, so it’s important you really consider your options before making a purchase.

When choosing a window colour, it’s easy to overlook a few important details. Make sure the shade suits your home’s architectural style rather than simply following current trends. Think about how the colour will look from the inside too, as frames can influence the feel of a room. Always check colour samples in natural light, since colours can look very different compared to indoors. Finally, avoid trendy shades that may date quickly, so your windows stay timeless for years to come.

Make your home stand out

With more colour choice than ever before, windows have become a defining feature of modern home design. Whether you prefer warm, earthy tones or bold, contemporary shades, the right finish can elevate kerb appeal, complement your interior style and add lasting value. By choosing colours that suit your property and reflect how you want your home to feel, you can create a look that remains striking, personal and future ready throughout 2026 and beyond.
