When it comes to updating your windows, the style and colour you choose play a major role in how your home looks and feels—not just inside, but from the kerb too. One colour that’s becoming increasingly popular across the UK, particularly for those with heritage or character properties, is Chartwell Green. Elegant, understated, and rich in heritage charm, this beautiful shade is making a real impact.
At Staywarm Energy, we’ve seen a growing demand for Chartwell Green windows and doors. Here’s why this trend is here to stay—and why it might be the perfect choice for your home.
What Is Chartwell Green?
Chartwell Green is a soft, sage-like green with subtle grey undertones. Inspired by the colour palette of classic English country homes, the name itself is said to originate from Chartwell House, the former home of Sir Winston Churchill, whose shutters and doors were painted this distinctive hue.
It’s a timeless shade that blends beautifully with natural stone, render and brickwork, making it an ideal choice for rural cottages, historic buildings, and even modern homes that want to add a traditional twist.


The Perfect Colour for Heritage Homes
If your property is older or has period features, then you’ll know how tricky it can be to find modern upgrades that respect the original character of your home. Chartwell Green offers the best of both worlds.
The colour pairs especially well with white or cream facades, traditional window styles such as flush sash or vertical sliding windows, and heritage ironmongery like monkey tail or teardrop handles. It enhances the authenticity of listed or conservation-area properties while offering all the benefits of modern window technology.
It’s not just for the countryside either—Chartwell Green adds a calming, sophisticated tone to urban terraces, townhouses and even newly built properties, giving them a distinctive edge.
Why It’s So Popular Right Now
Chartwell Green isn’t just a pretty face—it’s a colour that reflects current design trends. As homeowners look to soften their exterior palettes, earthy and muted tones are rising in popularity. Chartwell Green provides just the right amount of colour without overpowering the rest of your home’s look.
And because it’s such a calming, natural shade, it complements a wide range of materials and garden settings. Whether you have a wildflower garden, rustic cobblestones or manicured hedges, Chartwell Green blends in beautifully while adding a fresh update.
