Composite Decking vs Wood: Ultimate Comparison Guide 2025

Composite decking costs 50-80% more upfront (£110-200/m² vs £25-90/m² for timber) but requires zero maintenance versus £150-300 annually for wood. Over 10 years, costs converge. Modern premium composites like Millboard achieve realistic wood aesthetics with embossed grain and color variation. Timber offers authentic feel and natural aging but demands annual oiling/staining. Composite lifespan: 25-30 years vs 10-20 years for wood. Performance comparison includes heat retention, slip resistance, and environmental impact.
