Introduction
If you’re planning a new garden deck or replacing an existing one, you’ve likely considered traditional timber. While it offers a warm, natural look, timber decking can come with a long list of issues — from rot and algae to high ongoing maintenance.
Fortunately, there are now several high-performance alternatives available that offer better durability, lower upkeep, and long-term value. In this guide, we explore the best timber decking alternatives, and help you choose the right solution for your home.
Why Look Beyond Timber?
Timber decking has been a garden favourite for years, but it’s not without its challenges:
- High maintenance: requires regular staining, sealing or oiling
- Prone to rot and mould: especially in shaded or damp areas
- Slippery when wet: especially without anti-slip treatments
- Splitting and warping: natural expansion and contraction over time
- Environmental concerns: tropical hardwoods raise sustainability issues
For many homeowners, these issues lead to additional cost, effort, and shorter deck lifespan.
Top Alternatives to Timber Decking
1. Composite Decking
Composite decking combines visual appeal with impressive durability. Made from a blend of materials (often mineral or polymer composites), it replicates the look of timber without the traditional drawbacks.
Benefits:
- Low maintenance: no sealing or staining required
- Slip-resistant: ideal for wet or shaded areas
- Long lifespan: many products last 25+ years
- Consistent appearance: won’t fade, split or warp
Millboard composite decking goes a step further. It’s:
- Wood-free and non-porous
- Moulded from real oak boards for authentic texture
- Built with a durable Lastane surface for slip resistance and stain resistance

2. Aluminium Decking
Aluminium is a strong, non-combustible material often used in commercial or high-rise settings.
Pros:
- Excellent structural strength
- Fire-rated and rot-proof
- Durable surface finish
Cons:
- Feels cold and hard underfoot
- Limited aesthetic appeal for home gardens
- Can become hot in direct sun
Best suited for balconies, roof terraces or public walkways.
3. PVC / Plastic Decking
Made entirely from plastic, PVC decking is another low-maintenance option. It’s affordable and resistant to water, rot and insects.
Pros:
- Lightweight and easy to install
- Low cost
- Doesn’t absorb moisture
Cons:
- Can look and feel artificial
- Susceptible to UV fading or brittleness over time
PVC is typically chosen for budget-conscious projects or temporary decking.
4. Stone or Porcelain Paving
Although technically not decking, porcelain or stone paving can be a durable alternative for level garden surfaces.
Pros:
- Very hard-wearing
- Available in a variety of colours and textures
- Non-combustible
Cons:
- Can be cold and hard underfoot
- Limited use in raised or suspended decking areas
Best for patios, paths and formal seating areas.
How to Choose the Right Decking Alternative
When weighing up the options, consider the following:
- Aesthetics: Do you want a natural timber look or something more contemporary?
- Maintenance: How much time do you want to spend on upkeep?
- Comfort: Will people walk barefoot or sit directly on the deck?
- Location: Is your space shaded, coastal or prone to wet weather?
- Sustainability: Are you looking to reduce your environmental footprint?
