Best composite decking brands in the UK

There is no single best composite decking. We compare brands on facts you can check: capped surface, solid or hollow core, board sizes, warranty length and conditions. We have not lab-tested these boards; the table shows what each manufacturer publishes.

How we compare

We have not lab-tested these boards, so we do not give star ratings or test scores. We compare what each manufacturer publishes: how the board is built (capped or uncapped, solid or hollow, and the material), the widths, thicknesses and lengths on offer, the warranty length and its conditions, and whether a dated price is available.

Products are listed A to Z. A retailer cannot pay to move a product up. Our methodology explains the details.

Which board suits which job

If up-front cost matters most, compare the per-m² prices on the prices page and read the warranty conditions before you buy. For heavier or commercial use, look for boards with a stated commercial warranty. If you want a board with no wood content, Millboard describes its boards as resin and mineral.
