The best composite decking can create a fabulous garden feature that makes room for dining or relaxing. You can use it for a simple ground-level deck of any size, or far more extensive landscaping with different levels and steps in between. You can get the look you love, too. Composite decking comes in a huge range of colours and can pull off the appearance of hardwoods, and replicate its grain patterns, too.

If you’ve already settled on composite decking rather than hardwood or softwood, you’ll likely also be attracted by its durability and its low maintenance credentials as well.

The composite decking on our list includes different shades and looks, so you can complement the other hard landscaping in your garden as well as its planting and overall style. Read on to see our top picks, or check out our list of the best decking for a wider choice including wooden decking.

Timber appearance

If you want the look of wood, this is a top option. It’s made to have the appearance of natural grain plus the depth of colour wood has.

Fade resistance

These boards have a capped outer layer, which is designed to increase protection from fading in the sun as well as from the elements.

Secret fixings

This decking has a special clip system so that when you’ve built the deck you can’t see the fixings.

Set size 

Like the idea of getting everything you need to build a 2.4 x 2.4m deck in one ready-to-use package? Then the Homebase Ecodek Composite Deck Kit is for you.

All you need

You’ll get everything that’s required if you opt for this design. That means the deck boards of course, but also pressure-treated timber joists for the base, side fascias, colour matched screws, spacers and even the drill bit needed. You will need a saw to cut the timber joists to size, though.

Grain – or not

These grey boards have a natural wood grain effect on one side and a rigid profile on the other, which looks contemporary, so you can choose which you have on show.


The boards, which have a solid core, are made from recycled high-density polyethylene and beech hardwood fibres from sustainable sources, and they’re UK manufactured.

Won’t suit cottage-style gardens

B&Q Neva Anthracite Grey Composite Deck Board is a good looking and affordable design.

Contemporary colour

Anthracite grey won’t suit every style of plot – but there are plenty it will. The finish looks modern and this shade has become popular for bi-fold doors and window frames, so you well might want to continue your colour choice on the deck.

Reversible boards

They’re all one colour, but the boards do have a different profile on each side, to give you a choice of effect.

Sticky end

Some reviewers have reported that the labels have been tricky to remove and recommend arming yourself with a sticky remover to get the residue off.
