Composite decking vs timber decking
Choosing garden decking used to be a relatively easy task, not least because there weren’t many options to choose from. But gone are the days where we’re just limited to choosing grooved and reeded timber decking boards.
With the introduction of composite decking, a whole new world of style, colour, and flexibility has become available.
So when you’re searching for the perfect decking, it’s important to understand the difference between composite and timber and what’s most suitable for your outside space.
Timber decking has long been a popular way to create sociable spaces in gardens and outdoor areas.
Advantages of timber decking
- Hardwearing and has a long life with the right maintenance
- Treated to withstand rot and fungi
- Eco-friendly material, responsibly sourced from managed forests
- Easily adaptable to any type of space
- Easy to install for most competent DIYers
- Cost-effective way of creating a social outdoor area
Disadvantages of timber decking
The main disadvantage to timber decking is the maintenance that it requires to look its best.
To keep them in the best condition, wood decking boards need a good clean and treatment each year.
Decking treatments could include using decking oils and specialist protectors. Some decking paints and stains also include waterproofing and protecting agents.
“Timber decking can last a lifetime if treated to Use Class 4 and maintained using appropriate products”, says Bob Tee, Timber Commercial Manager at Elliotts.
Use Class 4 timber (also known as UC4) is one of the highest treatment grades of timber and has a long service life against rot and decay.
UC4 timber will usually be used in projects that involve being in contact with the ground or water, such as garden decking and fencing.
C24 is stronger and more resilient than C16 timber and it also looks better, making it a popular choice for applications that are going to be visible, like timber decking.

Composite decking has come a long way in the last 10 years from looking like plastic to looking so identical to authentic timber decks that it can sometimes be hard to tell the difference.
Advantages of composite decking
- No need for annual maintenance
- No rotting, warping, or splinters
- No colour fading
- Stain resistant
- Weather-resistant (UV and frost)
- High anti-slip ratings
Disadvantages of composite decking
The main disadvantage of composite decking when compared to timber decking is the initial cost.
Due to the high quality of the materials and the labour involved in producing the boards, composite decking has a higher price point than timber. But it can be argued that the initial outlay is offset by its other features.
“Colour permanence may also be seen as a disadvantage of composite decking. Timber decking can be stained and painted your favourite colours, but you’ll be unable to change the colour of your composite decking unless you change the boards,” says Victoria Anderson, Landscaping Category Manager for Elliotts.
Popular composite decking brands, like Piranha and Millboard are eco-friendly.
Over a third of the raw materials used for making the structural core of Millboard is recycled and boasts a CO2 footprint that matches a bunch of bananas.
And Talasey's composite range, Piranha, is a responsibly sourced range of composite decking made from recycled materials and FSC® certified.
Composite decking needs a solid foundation to ensure stability and longevity.
Our ranges of Millboard and Piranha composite decking offer full installation solutions, or you can also use a normal timber sub frame.

“There are now budget ranges that are closer in price to timber decking, but these are prone to cracking, being hot underfoot in the sun, and colour fade.
At Elliotts, we have chosen products that will last so that you can fit and forget – Millboard and Piranha.”
Composite Decking vs Timber Decking: Which is Best?
Want to create a safe space for children to play? With incredible anti-slip properties and stain resistance, composite would be the best choice for worry-free use.
Need decking that is easy to maintain? Whether you’re low on time or skill, composite decks need little maintenance and provide a ready-to-go space all year round.
Need to keep an eye on the budget? Timber decking would provide a great deck whilst looking after the pennies.
Prefer natural materials and don’t mind some upkeep? Timber decking is a more obvious choice for those who prefer earthly materials and are happy to put some love and time into keeping a good-looking deck.
“Nothing beats the feel and lustre of genuine timber, and timber sourced sustainably is always the greener option,” says Bob Tee, Timber Commercial Manager at Elliotts.
