Composite Decking vs. Wood: Decking Cost Comparison
When it comes to decking, the big question is always: composite decking or wood? Both have their fans, and both have their quirks. But if you’re thinking about your budget, you want to know which option gives you the best bang for your buck. Today, I’m diving into the decking cost comparison between composite decking and traditional wood. Let’s break it down, step by step, so you can make the smartest choice for your next project!
Decking Cost Comparison: Composite vs. Wood
First off, let’s talk about the upfront costs. Wood decking usually has a lower initial price. Softwoods like pine or spruce are often the cheapest options. You can pick up treated timber for a reasonable price at places like Foxhills Timber. Hardwood options like oak or cedar cost more but last longer.
Composite decking, on the other hand, tends to be pricier upfront. It’s made from a mix of wood fibres and plastic, which means it’s engineered to last longer and resist rot, insects, and weather damage. This durability comes at a cost, but it might save you money in the long run.
Here’s a quick breakdown:
Wood decking: £15 - £30 per square metre (depending on type and treatment)
Composite decking: £40 - £70 per square metre
Keep in mind, these prices can vary based on quality, supplier, and location. But the key takeaway is that composite decking costs more initially.

What About Maintenance Costs?
Now, the story doesn’t end with the initial price. Wood decking needs regular maintenance. You’ll want to stain or seal it every couple of years to keep it looking good and to protect it from the elements. This means buying sealants, stains, brushes, and maybe even hiring a pro if you’re not up for the job.
Composite decking is low maintenance. It doesn’t need staining or sealing. A simple clean with soap and water usually does the trick. This saves you time, effort, and money over the years.
Here’s a rough estimate of maintenance costs over 10 years:
Wood decking: £200 - £400 (staining, sealing, repairs)
Composite decking: £50 - £100 (cleaning supplies)
So, while wood decking is cheaper upfront, it can add up with maintenance. Composite decking’s higher initial cost might be balanced out by lower upkeep.
How much does a 20x20 composite deck cost?
Let’s get specific! Say you want a 20x20 foot deck (about 6x6 metres). How much will it set you back if you go composite?
Area: 400 square feet (about 36 square metres)
Composite decking cost: £40 - £70 per square metre
That means your decking boards alone could cost between £1,440 and £2,520. Add in the cost of joists, fixings, and labour if you’re hiring someone, and you’re looking at a bigger investment.
For comparison, a wood deck of the same size might cost between £540 and £1,080 for the timber alone. But remember, you’ll need to factor in maintenance and potential repairs over time.

Durability and Lifespan: What’s the Real Cost?
When you’re thinking about cost, don’t forget lifespan. Wood decks can last 10-15 years with good care. Hardwoods can last longer but cost more upfront. Softwoods might need replacing sooner.
Composite decking can last 25 years or more. It resists rot, warping, and insect damage better than wood. This means fewer repairs and replacements, which saves money in the long run.
So, if you’re planning to keep your deck for a long time, composite decking might be the smarter financial choice despite the higher initial cost.
Which One Should You Choose?
Choosing between composite decking and wood comes down to your budget, style, and how much time you want to spend on maintenance.
If you want a lower upfront cost and don’t mind regular upkeep, wood decking is a solid choice.
If you want low maintenance and a longer-lasting deck, composite decking is worth the investment.
