Timber vs Composite Decking | Pros, Cons and Costs
Choosing the right decking material is a crucial step when planning a garden project. The two most common options in the UK are timber decking and composite decking. Both offer unique benefits in terms of price, appearance, durability, and maintenance. This guide compares the key differences to help you choose the most suitable decking for your outdoor space.
What Is Timber Decking?
Timber decking is made from natural wood, usually softwood or hardwood, and remains a popular choice due to its affordability, versatility, and traditional appearance.
Types of Timber Decking
- Softwood decking boards: cost-effective and pressure-treated for outdoor use.
- Hardwood decking boards: denser, longer-lasting and visually premium.
Advantages of Timber Decking
- Natural, timeless look
- More affordable than composite
- Easy to cut, shape and install
- Can be sanded, stained or oiled
- Well suited for DIY projects
Considerations
- Requires regular maintenance
- May fade or weather over time
- Can become slippery if not cleaned
- Some boards may warp slightly with weather changes
What Is Composite Decking?
Composite decking is a manufactured product made from wood fibres and plastics. It is designed to be durable, low-maintenance, and consistent in appearance.
Advantages of Composite Decking
- Very low maintenance
- No need for oiling, staining or painting
- Highly resistant to rot, moisture and UV exposure
- Consistent colour and appearance
- Long lifespan
Considerations
- Higher upfront cost
- Can retain more heat than timber
- Less flexible to cut or customise
- Repairs can be difficult if damaged
Cost Comparison
Timber Decking Costs
Timber is generally the more budget-friendly option. Softwood is the lowest-cost choice, while hardwood offers premium durability at a higher price point.
For cost-conscious projects, reject decking provides strong value for non-visible or utility areas.
Composite Decking Costs
Composite decking requires a higher initial investment but minimal ongoing maintenance. For homeowners wanting long-term convenience, this can offer excellent value over time.
Maintenance Requirements
Timber Decking
Timber requires ongoing care to maintain its performance and appearance. This typically includes:
- Cleaning dirt and algae
- Re-oiling or re-staining using decking oils and treatments
- Occasional sanding
- Monitoring for moisture or wear
Composite Decking
Composite decking requires far less maintenance:
- Occasional washing with water
- No oiling, painting, or staining
- High resistance to moisture and UV damage
This makes composite ideal for busy households, rental properties and low-maintenance gardens.
Appearance and Style
Timber Decking
Timber offers a warm, natural aesthetic with visible grain and texture. Softwood decking can be stained in various colours, while hardwood develops a striking silver patina if left untreated.
Composite Decking
Composite decking provides a modern, uniform look available in a wide range of colours. It is consistent and contemporary, although some customers prefer the authenticity of real wood.
Durability and Lifespan
Timber Decking
With proper maintenance, timber decking can last many years. Hardwood decking performs exceptionally well in high-traffic areas.
Composite Decking
Composite decking typically has a longer lifespan, offering strong resistance to moisture, fading and general weathering without significant upkeep.
Environmental Considerations
Timber Decking
Timber is one of the most environmentally responsible choices when sourced from sustainable forests. It is biodegradable and has a lower manufacturing footprint compared to composite products.
Composite Decking
Composite often includes recycled materials, but is not biodegradable and has a more intensive manufacturing process. Recycling options at end-of-life are limited.
Which Decking Material Should You Choose?
Choose Timber Decking If You Want:
- A natural, traditional look
- A more affordable option
- A material that is easy to cut and install
- Flexibility to stain or oil in different finishes
Choose Composite Decking If You Want:
- Minimal maintenance
- Long-lasting performance
- A consistent, modern appearance
- Excellent resistance to moisture and fading

Both timber and composite decking offer strong benefits. Timber provides a natural, warm aesthetic and excellent affordability, while composite offers long-term convenience and low maintenance.
