Not sure what a fencing kit includes or which system is right for your garden? Our buyer’s guide to composite fencing kits explains the different options.
The composite material means no staining, sealing or painting is needed, and it resists rot, mould and warping. Designed specifically for existing concrete posts, these smooth and grooved panels create a simple slot-in composite fencing system using the included U-shaped connectors.
Available in classic shades such as anthracite grey, they can also be paired with our matching composite decking boards for a coordinated garden design.

FAQ About Our Smooth Fence Panels
1 Will the fencing boards fade over time?
Yes, like all composite products, you can expect around 20–30% colour fade due to UV exposure. This natural softening of the colour is factored into the design and shouldn’t affect the overall look, meaning dark grey will stay dark grey, but lighter versions will fade accordingly.
2 Can I install this fencing by myself?
Absolutely. The panels are lightweight and slot together with ease. No specialist tools or tradespeople are required; just follow our simple composite fencing installation guide.
3 Is it safe around pets and children?
Yes! The boards are free from splinters and resistant to stains, muddy paws, and sticky fingers. Composite also doesn’t overheat like metal fencing, making it a safer choice for little hands.
4 Do I need gravel boards?
For a standard 6ft x 6ft setup, a 300mm gravel board is factored into the number of boards required. If you’re skipping the gravel board, simply purchase two extra fence slats to achieve the same coverage.
