How Much Does Composite Decking Cost in Ireland? (2026 Guide)
Composite decking has become a top choice for Irish homeowners looking for a durable, low-maintenance alternative to traditional timber decks. However, costs can vary widely depending on material quality, the complexity of your design, and whether you’re building in Dublin or elsewhere in Ireland.
In 2026, you can expect to pay between €65 and €170 per square metre for supplied and installed composite decking. Entry-level options (material only) start at around €35–€45/m², while premium boards can run up to €90/m² or more. Add installation – which ranges from €30–€80/m² depending on site and design complexity – and a mid-sized project (20–40m²) comes in at €2,000 to €4,500. Larger projects may exceed €8,000, particularly if groundwork is involved.
To avoid surprises, it’s vital to get detailed quotes inclusive of VAT. Comparing several reputable contractors and understanding what drives price differences will help you find the right balance of quality and value for your garden.

What Impacts Composite Decking Costs?
Composite decking prices aren’t just about the board you choose – several factors will impact your final bill. Understanding each helps you plan and budget sensibly.
- Deck size: Larger areas cost more, but may benefit from lower per-m² rates.
- Complexity: Steps, curves, or raised foundations increase both material waste and labour costs.
- Material quality: Premium boards not only look better, they often last longer – but at a price.
- Site preparation: Poor ground, uneven surfaces, or access issues mean additional groundwork and expense.
- Location: Expect higher installation costs around Dublin and other cities due to demand and higher living costs.
Material Choices: Entry-Level to Premium
2026 sees a wide range of composite decking products on the Irish market. Entry-level products (€35–€45/m²) offer solid performance and are suitable for basic decks. Mid-range boards (€45–€65/m²) bring better durability and more stylish finishes. At the top end, premium boards (€65–€90+/m²) deliver top-spec aesthetics, sometimes with textured grains or enhanced warranties.
Installation: What’s Involved (and What It Costs)
Labour is a significant piece of your total spend. Standard installation typically runs €30–€50/m², covering a straightforward fit on a prepared base. If your deck requires more complex construction – say, a raised platform, non-rectangular layout, or integrated steps – expect costs of €50–€80/m². This reflects the extra time, skill, and materials required.
Always check if your quotation includes VAT (23%) and what preparation work is included, as unforeseen groundwork remains a common source of extra cost.
Practical Cost-Saving Tips
- Get at least three itemised quotes, clearly stating material and labour rates including VAT.
- Ask contractors for references and examples of past composite deck work.
- Consider a simpler design if you want to keep costs low.
- Schedule your project for the off-peak season if possible – you might get better rates outside the summer rush.
- Keep routine cleaning in mind—composite decking is lower-maintenance than timber, but still needs an occasional wash.
Regulations, Grants, and the Bigger Picture
Currently, composite decking isn’t covered by energy efficiency grants such as those offered by the SEAI. Always ensure you’re in line with local planning guidelines if your deck is raised or especially large. Reliable and experienced installers are invaluable – they’ll help you avoid both regulatory pitfalls and expensive mistakes.
