Grey is the most popular choice in composite decking, and for good reason.
It's clean, contemporary and endlessly versatile, sitting beautifully against render, glazing, brick and greenery alike. Whether you want a bold, modern statement or a soft, calming backdrop, there's a grey for it.
Within the grey family you'll find two clean, solid tones; dark grey and light grey, plus rustic stone, a grey-toned, stone-look board from our rustic decking range for anyone after a more interesting finish. All are built from the same, low-maintenance composite. No oiling, no staining, no sanding: just a deck that still looks like new in ten years.
Is Dark Grey for me?
Bold, sleek and unmistakably modern. Dark grey anchors a space and looks striking against pale render, black-framed glazing and contemporary furniture. Its deeper tone is also the most forgiving with everyday marks, making it a confident choice for busy, high-traffic gardens and terraces.
Is Light Grey for me?
Soft, airy and calming. Light grey brightens a garden and makes smaller or enclosed spaces feel more open. It's a natural fit for coastal, Scandi and modern-minimal schemes, and pairs effortlessly with pale stone, timber accents and plenty of greenery.
Rustic Stone (part of our Rustic range)
The look of natural old aged timber but with a contemporary twist. From our rustic decking range, rustic stone is a multi-tonal grey with genuine depth and movement; textured and characterful rather than uniform. It's the perfect bridge if you're torn between decking and paving, and sits beautifully alongside porcelain and natural stone patios.

Your quick buying guide
Choose your finish. Every board features a realistic woodgrain texture, but each range offers a different look. Core delivers a deeper woodgrain effect, Rustic recreates the character of naturally weathered timber, while Supreme offers a sleek, contemporary matte finish.
Capped or uncapped? Premium and Supreme boards feature a protective polymer cap for enhanced resistance against stains, scratches and fading. Core and Rustic are uncapped, making them a more affordable choice while still offering far greater weather resistance than traditional timber.
Two looks in one. Core is our only reversible decking board, giving you two surface finishes to choose from. Stick to one style throughout or mix things up for a more individual look.
The finishing touches. Complete your decking with colour-matched fascia, trims, screws and clips, available across every range. Everything you need for a neat, coordinated finish with fixings that blend seamlessly into your deck.

FAQs
Which grey decking is the most popular?
All three sell well, but it comes down to the look you're after: dark grey for a bold, modern statement; light grey for a soft, open feel; rustic stone for natural, multi-tonal character. Ordering samples of all three side by side is the easiest way to decide.
Does grey composite decking fade?
Our boards are engineered to resist UV fading. You may notice very slight, even lightening in the first few months as the boards settle, after which the colour stays stable.
Is grey decking hard to keep clean?
Not at all — there's no timber upkeep. A wash with warm soapy water and a soft brush keeps every shade looking fresh. Lighter greys will show general dirt a little sooner than darker ones simply because of the tone, but both clean up the same way.
What's the difference between rustic stone and the plain greys?
Dark and light grey are solid, even tones. Rustic stone sits in our rustic decking range and is deliberately multi-tonal, with a stone-look texture and natural variation from board to board — a more organic finish.
Can I order samples?
Yes — we'd always recommend it. Grey reads very differently in sun and shade, so seeing the boards in your own garden light is the best way to choose.
Do you offer boards in 3.6m & 5m lengths?
All boards come in 3.6m length. Longer 5m boards are available in our core range only.
Why composite over timber?
Low maintenance — no sanding, oiling or annual treatment. An occasional wash keeps it looking new.
Durable — resists rot, warping and water damage that shorten the life of timber decks.
Fade resistant — Minimal fading, whilst holding its colour season after season.
Eco-conscious — made from recycled wood and plastic fibres, reducing landfill and deforestation.
How do I calculate how many grey decking boards I need?
A quick rule of thumb: one 3.6m board covers around half a square metre, so you'll need roughly 2 boards per m². Add about 10% on top for cuts, waste and the small expansion gap between boards.
