Composite (WPC) decking vs timber

Cost: A fixed canopy costs less per m² than an opening louvre roof - use the price calculator for an indicative figure.
Flexibility: Fixed canopy is always covered; louvre roof adjusts to conditions on demand.
Maintenance: Fixed canopy needs only cleaning and a fixings check; a louvre roof has a motor, drainage channels and pivot points to keep serviced.
Consent complexity: Both depend on the specific structure, but the electrical work for a motorised system is an extra factor to plan for.
Lifespan: Both use aluminium framing and are built to last well beyond their warranty period with basic care - fewer moving parts on a fixed canopy is one reason it needs less attention over time.

Timber is the traditional choice. Composite decking trades some of timber's natural grain for far less upkeep.

Side by side

	Deck	Timber decking
Maintenance	No painting, staining or sealing	Regular oiling or staining to keep it protected
Moisture	Mildew-proof, anti-corrosion, anti-crack	Needs protecting against rot and cracking
Surface	No timber burrs or splinters	Can splinter as it weathers
Colour	Anti-UV, resists colour fading	Greys naturally unless re-coated
Fire	Flame-retardant	Combustible timber

Choose composite for low upkeep, a splinter-free surface for kids and pets, and a deck under a roof that stays looking new.

Choose timber if you want natural grain and don't mind regular oiling.
