The Ultimate Guide to Timber & Composite Decking in the UK (2025)

Introduction

Planning a new deck for your garden or outdoor project? Choosing the right decking material is key to achieving a stunning look and long-lasting durability.

At MSS Timber Merchants, we supply both traditional timber decking and advanced composite decking solutions like Oakio IniWood and Oakio Proshield — giving you the best of both worlds.

This guide covers everything you need to know about decking in 2025: timber vs composite, product options, and maintenance tips.


1. Why Decking Remains Popular in the UK

  • Stylish outdoor living: Adds usable space for entertaining or relaxing.

  • Durable: Modern materials resist weather and wear.

  • Value: Enhances property appeal.

  • Sustainability: Options available in responsibly sourced timber or recycled composites.


2. Timber Decking Options

Softwood Decking

  • Budget-friendly, pressure-treated for outdoor use.

  • Great for residential gardens.

Hardwood Decking

  • Premium natural appearance.

  • Resistant to rot and insects.

  • Long-lasting with proper care.


3. Composite Decking: Oakio IniWood & Proshield

Composite decking blends wood fibres with recycled plastics for a low-maintenance, eco-conscious alternative to timber.

Oakio IniWood Decking

  • Made with 35% plastic and 55% reclaimed wood fibre.

  • Natural wood-like appearance with the durability of composite.

  • Slip-resistant and low maintenance.

  • Available in a range of colours and finishes.

Oakio Proshield Decking

  • Advanced capped composite decking with a protective shield.

  • Resistant to stains, fading, and scratches.

  • Virtually maintenance-free — no oiling or sealing required.

  • Long lifespan, perfect for high-traffic areas.

👉 Both Oakio ranges combine sustainability with performance — making them ideal for modern UK gardens.


4. Treated vs Untreated Timber

  • Treated timber: Pressure-treated to resist moisture and decay — essential for outdoor use.

  • Untreated timber: Requires staining and sealing; less durable outdoors.


5. Choosing the Right Decking for Your Project

Ask yourself:

  • Budget → Softwood = affordable; Hardwood/Proshield = premium.

  • Maintenance → Timber = needs seasonal care; Composite = low effort.

  • Style → Natural look of hardwood vs sleek modern composite finishes.

  • Durability → Composite (Proshield especially) offers the longest lifespan.


6. Installation Tips

  • Use pressure-treated joists and supports.

  • Leave expansion gaps for both timber and composite boards.

  • For Oakio decking, follow manufacturer installation guidelines to ensure warranty validity.


7. Maintenance Guide

Timber Decking

  • Clean annually with decking cleaner.

  • Reseal or re-oil every 1–2 years.

Oakio IniWood Decking

  • Wash with mild soap and water.

  • No staining, painting, or sealing required.
