Composite Decking vs Timber: Which Should You Choose?

Planning a new deck? The first big decision is material — and in 2026, it's essentially a two-horse race between traditional timber and composite decking.

What Is Composite Decking?

Composite boards are engineered from recycled wood fibres and recycled plastics, bound with polymers. They look and feel like natural timber but resist rot, warping, splintering, and insect damage. Modern boards feature advanced 3D woodgrain embossing and many are dual-sided, offering two finishes from one product.

Maintenance: Composite Wins Decisively

Timber decking in the UK requires annual sanding, staining or oiling, and board replacement. In wet, shaded areas, timber deteriorates quickly.

Composite requires almost nothing. No sanding, no staining, no sealing. A soapy water wash once or twice a year is all it takes.

Durability and Lifespan

Treated softwood: 10–15 years with maintenance. Quality composite: warrantied for 25 years and often lasts longer. It won't rot, split, or warp, and it's splinter-free — important for children and pets.

Cost: Upfront vs Lifetime

Softwood starts at £3–5 per linear metre; composite from £8–15. But over 20 years, factoring in treatments, replacements, and time, composite almost always works out more cost-effective.

Sustainability

Composite is made from recycled materials and can itself be recycled. Treated softwood involves chemical preservatives that can leach into soil, plus replacement waste every decade.

Appearance

Timber has unbeatable natural warmth in year one, but fades to silvery grey quickly without treatment. Composite retains its colour consistently. In 2026, warm neutrals — pebble, driftwood, smoked cedar — are the trending colours.

The Verdict

For most UK homeowners, composite is the better investment. It lasts longer, costs less over time, and performs better in the British climate.
