Comparison
Composite vs timber decking: which should you choose?
Timber is cheaper upfront and natural; composite costs more to buy but needs almost no upkeep and lasts longer, so the lifetime cost flips. Premium composite like Millboard looks closest to real wood.
The verdict
Timber decking costs less to buy and gives you real wood, but it needs regular cleaning, oiling or staining and will not last as long. Composite decking costs more upfront but needs almost no maintenance, will not rot, splinter or fade much, and lasts far longer, so over its life it often works out cheaper. The gap on looks is closing: premium composite boards such as Millboard are moulded from real timber and are hard to tell from wood. Choose timber for budget and a natural feel, composite for low-maintenance longevity, especially near water.

The case for each
What suits which site
The honest way to compare decking is over its whole life, not just at the till, because that is where the two materials swap places. Timber is cheaper to buy and it is real wood, which some people will always prefer. But it needs looking after: cleaning, and oiling or staining on a cycle, and even then it weathers, can splinter and will eventually need replacing. The upfront saving is partly borrowed from the years ahead. Composite costs more to buy and almost nothing to keep. It does not rot or splinter, holds its colour, and lasts far longer, so across its life it often works out cheaper t
Common questions
Common questions
Over its life, usually yes. You pay more upfront but save the annual maintenance and replace it far less often. Near water or for a low-fuss owner it is the clear choice.
Premium composite such as Millboard is moulded from real timber boards and is very hard to tell apart. Cheaper composite looks more uniform and plasticky.
Composite, comfortably. It will not rot or splinter and holds its colour, where timber needs upkeep and eventually replacing.
