As we move into the spring renovation season, window colour trends for uPVC frames are taking a definite shape.

These selections are full of character and remain well suited to the architectural heritage and natural scenery of Britain. Whether you are planning a full renovation or a simple summer update, these latest trends and colours provide the perfect inspiration for your spring project.

What is a RAL?

RAL is a colour management system used throughout Europe, originally created in Germany. It began as a collection of 40 colours known as ‘RAL 840’. Before this manufacturers and customers had to exchange samples to describe a tint, whereas after RAL’s were developed they could rely on a number. The RAL system provides a universally recognisable palette of colours, ensuring precision and consistency for colour selection.

The RAL colour system now comprises over 2,500 colours all identified with a unique RAL code. Today, it stands as the most widely used Central European colour standard, applied across architecture, construction, industry, recreation, and road safety.

Agate Grey

Agate Grey - RAL Classic 7038

Agate grey, also known as the popular 'Painswick' finish, is a light grey with a subtle green undertone making it a very versatile choice. Agate is a perfect neutral for combining exterior materials such as render or cladding.

Agate grey is definitely the undisputed "King of 2026." It has replaced Anthracite as the go-to grey because it is softer and has a slight green undertone that blends perfectly with nature.

Looks great on traditional red brick homes, rendered properties and stone cottages.

Pebble Grey

Pebble Grey - RAL Classic 7032

Slightly more browned toned than agate, Pebble Grey is a warm, mid-tone taupe that is a sophisticated neutral colour. Pebble Grey offers a balance between cosy brown tones and refined grey, making it adaptable for various interior and exterior designs.

Looks great on period properties or pairing with render & cladding.

Anthracite Grey

Anthracite Grey RAL Classic 7016.

Anthracite grey has dominated the industry for the last few years. Now with other colours rising in popularity it has taken a backseat, but it still remains a highly popular choice. It provides a contemporary, industrial look but is also very timeless. Mostly popular with more modern buildings but it can also work well in a traditional setting.

Works well on modern properties as well as traditional properties with stone and natural materials.

Clay

Clay - RAL Design 080 80 05

Clay sometimes known as claystone is a stunning ‘greige’ colour. A warm and charming neutral, more muted than cream. Clay is a rich, earthy hue that creates the most charismatic and elegant of homes. A natural warm tone with subtle texture, Clay offers the perfect balance between classic and contemporary.

Best for brick and stone exteriors, cottage and rustic styles and new builds with organic colour palettes.

Jet Black

Jet Black - RAL Classic 9005

Jet black remains a staple choice for windows, especially for anyone looking for a bold, modern, minimalist aesthetic. It's pure colour that provides a striking contrast against lighter surfaces, making any window or door the standout feature of the property.

Suits modern and minimalist properties as well older homes as a replacement for steel.

Basalt Grey

Basalt Grey - RAL Classic 7012

A striking dark grey colour that takes inspiration from the colour of volcanic rock. It’s a slightly lighter shade than Anthracite grey and is a popular choice for modern and traditional homes. Basalt Grey can be a great alternative for those who like the look of anthracite but want something a little more understated. It can add a touch of depth to a space.

White

White - RAL Classic 9010

White will always remain an in demand choice for windows and doors and for obvious reasons. Its neutral, classic, complements the majority of architectural styles. White is also very easy to coordinate with other colours and styles. Unlike standard brilliant white, RAL 9010 offers a slightly softer, cleaner finish that feels more architectural and less plastic

Wood effect finishes

In recent years timber/wood effect windows have become increasingly popular. Foils such as Irish Oak, Golden Oak and Silvered Oak offer homeowners the perfect balance of beautiful wood appearance without the issues and ongoing care of real wood.

Today’s wood effect uPVC windows represent a real advance in window technology. Unlike real timber windows, which require regular sanding, painting and treating, these modern alternatives offer outstanding thermal performance while maintaining the authentic appearance of wooden frames. The realistic wood effect finish is so convincing that even from close up, it’s virtually impossible to distinguish from real timber.
