Making light work of heavy footfall, you can rely on Urban for a solid deck for years to come. Tough and long-lasting, our resilient decking is perfectly placed in hotels, bars and restaurants as well as outside any home.

Easy upkeep

Our simple fixing packs make your deck quick and easy to install, while its low maintenance surface gives you more time to enjoy it. Because Spring should be about buying the burger buns, not staining the decking.

Made in Britain

As with all good British things (socks with sandals, hosepipe bans, dodgy tan lines) our composite decking is made and managed right here in Britain. Our UK-based aftercare team and 20-year warranty makes Urban a cost-effective and reliable solution to your outdoors.

We don’t let spilt rosé, muddy paws and intermittent rain storms spoil our fun – or our decking. Stain-resistant, stress-free and barefoot-friendly: it’s time to worry less about sanding or sealing and more about slapping on the After Sun.


Urban decking’s embossed wood-grain surface is stain-proof. So, Ken from next door won’t get a chance to take over the hot dogs while you’re busy scrubbing out the wine stain. We guarantee you’ll always be King of the Grill.
