Composite Decking

Easy to install, composite decking is low maintenance as it won’t decay, warp or splinter and requires no staining or treating.
 

Backed by a 25-year product guarantee for peace of mind, composite decking is also slip resistant and barefoot-safe and, being made from recycled material, is friendly to the environment.

Choose from Composite Prime HD (which features a clip installation system) and the Smart Board (boards can be screwed through the face as with a timber installation).

Both ranges offer a 25-year guarantee.

Our composite decking is made from 100% hardwood flour combined with recycled plastic, giving you the natural look of timber decking without the ongoing maintenance. Whether you’re building a raised deck for entertaining, a level space for a hot tub, or a simple garden walkway, we stock everything you need in one place: decking boards, joists, fixings and accessories from our Chesham branch.

We supply and deliver composite decking across Chesham, Watford, Amersham and the wider Buckinghamshire and Hertfordshire area. Order online for delivery, or visit our Chesham branch to see the boards and colours in person.

Why choose composite decking over timber?

Composite decking has become a popular alternative to traditional timber decking, combining the appearance of natural wood with far less upkeep:

No staining or oiling — unlike timber decking, composite boards don’t need annual treatment to stay looking good.

Resists rot, splintering and fading — built to withstand the British climate without the maintenance timber requires.

Consistent colour and finish — every board looks the same, with no knots or grain variation to work around.

Long lifespan — a durable option for a deck that’s built to last with minimal ongoing effort.

If you’d prefer the natural look and lower upfront cost of traditional timber, take a look at our timber decking range instead.

Everything you need for your decking project

A composite deck needs more than just the boards. We stock the full range of supporting materials, so you can source your entire project from one local supplier:

Decking Joists: Every deck needs a solid sub-frame underneath it. Our pressure-treated C16 joists are strength-graded and regularised for easier handling, giving your composite boards a stable, long-lasting base.

Decking Accessories & Joist Hangers: Joist hangers make constructing a strong, secure sub-frame straightforward, and are available in more than one size to suit different joist depths.

Balustrading: Raised decks need a safe, attractive edge. Our balustrading and decking rail options let you frame your deck decoratively while keeping it safe to use.

Geotextile Membrane Laid beneath your decking, geotextile membrane stops weeds coming through while still allowing the ground underneath to breathe — a simple step that saves maintenance headaches later.

Timber Treatment: While composite boards themselves don’t need treating, the timber sub-frame and joists benefit from protection — browse our range of stains, oils and preservers.

Fixings & Decking Screws: The right fixings matter for a secure, long-lasting deck — we stock decking screws and fittings suited to composite board installation.

Post Mix & Postcrete For securing support posts on raised decks, our rapid-setting post mix makes light work of setting posts firmly in the ground.

FAQ

What is composite decking made from? 

Our composite decking is made from 100% hardwood flour combined with recycled plastic, giving a durable, natural-looking finish without the maintenance timber decking needs.

Is composite decking better than timber decking for my garden? 

It depends on what you’re after. Composite decking needs far less maintenance, no staining or oiling and resists rot and fading better than timber. Timber decking has a lower upfront cost and a more traditional look. We stock both, so you can compare in person at our Chesham branch.

Do I need joists to install composite decking? 

Yes, composite boards are laid on a timber sub-frame just like traditional decking, so you’ll need decking joists and joist hangers to build a stable base underneath them.

Does composite decking need to be treated or stained?

No, that’s one of its main advantages over timber. The boards themselves don’t need staining, oiling or annual treatment. Any timber used in the sub-frame or joists underneath should still be treated for protection.

What areas do you deliver composite decking to? 

We deliver composite decking, joists, fixings and accessories across Chesham, Watford, Amersham and the wider Buckinghamshire and Hertfordshire area from our Chesham branch, or you’re welcome to visit us in person.

Can landscapers or contractors get trade pricing on decking? 

Yes, trade accounts are available for landscapers, contractors and tradespeople ordering regularly — see our Trade Enquiries page to set one up.

Can you recommend someone to install my decking? 

We supply the materials rather than install ourselves, but we work with a network of trusted local installers who can be found through our Installer Network page.
