What is an RAL colour?

RAL is a standardised European colour system that keeps shades consistent across different materials. Whether it’s metal, paint, or another finish, a RAL colour ensures your chosen shade is precisely and perfectly matched throughout your space.

Do you offer all RAL colours?

Not every shade, but all the favourites. With thousands of RAL options available, we’ve selected the most popular RAL colours – widely used in construction and interior design – to ensure you have a versatile range of options.

Choose your colour in person

Colour is an essential part of your design, and seeing it in real life makes all the difference. Whether you’re looking for a classic RAL shade or a bespoke option, we have a wide range of samples you can touch, compare, see in natural light, and hold against different finishes to find the right one for your space.

From deep mattes to high-gloss, soft sheens to textured metallics, every finish adds its own character. We even have shelves dedicated just to whites – because the details matter. And it’s not just about the radiator. We’ll help you match valves and accessories to keep everything beautifully balanced.

Bring us your mood boards, room plans, or just a spark of an idea – we’ll help you choose a colour that works perfectly in your space.

What is a BTU and why do I need it?

BTU (British Thermal Unit) measures how much heat a radiator gives out.

Check your BTU before buying. Too low means a chilly room. Too high, and you’ll waste energy.

What size radiator do I need for my room?

The right size radiator keeps your space warm and comfortable.

Many factors affect heating – room size, layout, insulation, and more. Find your best fit with our size guide.
