Radiator Colour Trends 2026: What UK Homes Are Really Choosing

Walk into any showroom and someone will tell you that black is in or that grey is over. We wanted evidence rather than opinion, so we analysed five years of UK Google searches for radiator finishes. The picture is clear: black and white radiators are rising, grey and anthracite are fading fast, and brass has gone from almost nothing to a genuine trend. Here’s what the data shows, why it’s happening, and how to choose a colour for your room without giving up any heat.

What five years of UK search data tells us

We compared five searches in Google Trends (black, white, grey, anthracite and brass radiators) across the UK, week by week, from October 2021 to September 2026. Google Trends scores interest from 0 to 100 against the busiest week, so the figures show how the finishes compare with each other and how that has changed over time. They are not raw search counts.

12-month averages (October to September) of the weekly Google Trends index for UK web searches. 100 is the busiest single week for any of the five terms.

Two things stand out. First, this isn’t a case of black replacing white: both are growing, and grey is paying the price. Second, brass barely registered until 2024, then more than tripled in a year and more than doubled again. That’s the typical shape of a trend moving from designers’ mood boards into ordinary homes.

1. Black radiators: the new neutral

Black has moved from bold statement to dependable neutral. It frames a room the way black window frames and metal light fittings do, and it suits both ends of the market: sleek verticals in new builds and traditional column radiators in Victorian and Edwardian terraces.

Where black works best:

• Period homes with dark-painted woodwork or original features, where a black column radiator looks as if it has always been there.
• Warm neutral rooms in mushroom, taupe or putty, where black adds definition without feeling cold.
• Kitchens and extensions with black taps, handles or glazing bars, so all the metalwork reads as one scheme.

Worth knowing: dark finishes show dust more readily than white, so a quick wipe with a soft, dry cloth every week or two keeps them crisp. Finish the look with black thermostatic valves, so there’s no flash of chrome at floor level.

2. White radiators: back in favour, and warmer

White never went away, but it has had a real lift. Pantone named Cloud Dancer (PANTONE 11-4201) its Colour of the Year for 2026, the first time it has chosen a white, and interiors have followed with soft, chalky whites in place of stark brilliant white.

A white radiator can do two jobs. Against white or off-white walls it disappears, which is ideal in small rooms or wherever you want the architecture to lead. Against strong colour it becomes a crisp outline, especially with the deep blues that are everywhere this year. Dulux’s Colours of the Year 2026 are a trio of indigo blues, and a white column radiator on an indigo wall is one of the easiest ways to make that look feel finished.

Tip: warm whites and cool whites can clash side by side. Look at the radiator finish next to your wall paint in daylight before you commit, or choose a RAL shade if you want an exact match.

3. Grey and anthracite: fading, but not finished

Grey was the default “designer” colour for most of the last decade, and anthracite (a very dark grey with a slight blue tint, usually matched to RAL 7016) was its radiator equivalent. Searches for both have fallen by around 40% since 2021–22 as homes move towards warmer palettes. That doesn’t make grey wrong. It’s now a considered choice rather than the automatic one.

Anthracite still earns its place:

• In kitchens with grey or blue-grey units, where it ties the radiator into the cabinetry.
• In industrial schemes with concrete, polished plaster or exposed brick.
• Where black feels too heavy, because anthracite reads softer in daylight.

4. Brass and gold: the breakout finish of 2026

Brass is the biggest mover in the data. Interest in brass radiators was almost nil in 2021–22; it more than tripled in 2024–25 and more than doubled again in 2025–26, to roughly eleven times its starting level. Google Trends also lists “gold radiator” and “antique brass radiator” among the fastest-rising radiator searches of the past 12 months. It’s part of a wider swing to warm metals in taps, lighting and door furniture.

How to use brass without it looking dated:

• Choose a brushed or satin finish over high shine. It looks more expensive and shows fewer fingerprints.
• Keep the rest of the palette calm. Warm whites, soft greens and navy all let brass glow.
• Repeat the metal once or twice in the room, such as a tap, a light fitting or cabinet handles, so the radiator looks planned rather than random.

Good to know: metallic finishes vary. Some are coatings and some are true metal, and heat output can differ between them. Always check the figure for the exact finish you want. We list it for every size on each product page.

5. Bold colour and colour-matched rooms

The most confident trend of all is colour itself. Colour drenching, where walls, woodwork and sometimes the ceiling are painted in one shade, has taken over from the single feature wall. A radiator in the wrong colour is the one thing that breaks the effect. The answer is a radiator made in a matching or complementary RAL shade.

Three directions we’re seeing:

• Deep reds and burgundies for dining rooms and snugs. A flame red (RAL 3000) radiator against a dark wall is pure drama.
• Greens, from mint to deep forest, for bedrooms and kitchens: calm, natural and easy to live with. See our mint green (RAL 6029) column radiator.
• Indigo and navy for studies and living rooms, in step with this year’s blues.

Our Colona column radiator can be ordered in a curated palette of 33 RAL shades, and many of our coloured aluminium radiators come in made-to-order finishes including navy blue, burgundy, gold and copper. Made-to-order colours take around 10–12 days.

Does the colour of a radiator change its heat output?

It’s one of the questions we hear most, usually as “do black radiators give out more heat?” The short answer is no, not in any way you’d notice.

A radiator warms a room in two ways: by convection (warm air rising off the surface) and by radiation (infrared heat given off by the surface). Convection doesn’t care what colour the radiator is. Radiation depends on how well the surface emits infrared, known as its emissivity, and at infrared wavelengths paint of almost any colour behaves the same way. Published engineering data puts oil paints of all colours at an emissivity of 0.92–0.96, and black lacquer or epoxy paint at around 0.88–0.89.

Where finish really matters is bare, polished metal. Polished chrome (about 0.06), polished stainless steel (about 0.08) and polished brass (about 0.03) reflect most infrared instead of giving it off, so the radiant part of their output drops sharply. That’s why a chrome towel rail feels less warm than a painted one of the same size.

How to choose the right radiator colour in 5 steps

1. Start with what’s staying. Floors, worktops, window frames, doors and skirting will outlast your paint colour, so your radiator should work with them first.
2. Decide whether to blend in or stand out. Matching the wall makes a small room feel calmer and larger. A contrasting finish turns the radiator into a feature, which works best with a good-looking design such as a column or tall vertical.
3. Match the metalwork. Valves, taps, handles and light fittings in the same finish make a scheme look deliberate.
4. Check the light. In north-facing rooms, warm finishes (brass, warm whites and reds) offset cool daylight. In bright south-facing rooms, cooler colours such as navy and grey hold up well.
5. Size it in your chosen finish. Choose the colour, then check the ΔT50 heat output for that size and finish against what your room needs.

Frequently asked questions

Are black radiators still in fashion in 2026?

Yes. UK search interest in black radiators is up 36% on 2021–22 and is now almost level with white, the long-standing favourite. Black has become a neutral rather than a statement, which is why it keeps growing.

Do black radiators give out more heat than white ones?

No. Paint of any colour gives off infrared heat almost equally well, and convection, which does much of a radiator’s work, isn’t affected by colour at all. Only bare polished metal finishes, such as chrome, give out noticeably less.

Should my radiator match my walls?

It depends on the effect you want. Matching (or colour drenching) makes a radiator recede and a room feel calmer. A contrasting finish turns it into a feature. Match in small or busy rooms, and contrast when the radiator is a design piece in its own right.

What’s the difference between anthracite and black?

Anthracite is a very dark grey with a slight blue tint, usually matched to RAL 7016. It reads softer than black, especially in daylight, and suits grey kitchens and industrial schemes. Black, such as RAL 9005 jet black, gives stronger contrast.

Can I get a radiator in any colour?

Many designs can be made to order. Our Colona column radiators come in a curated palette of 33 RAL shades, and many of our aluminium designer radiators offer made-to-order colours such as navy blue, burgundy, gold and copper. Allow around 10–12 days.

Is brass just a passing fad?

Nobody can promise that, but the data shows two years of sustained growth rather than a one-off spike. Brushed brass also sits well with long-lasting materials such as oak, marble and natural stone, which helps it age well.
