How much does decking cost in the UK?

As a guide, the average cost for the supply and installation of a medium-sized decked area (approx. 15–30m²) is:

• £2,400 for softwood decking
• £3,600 for hardwood decking
• £3,000 for composite decking

• £80 per m² for treated softwood decking
• £120 per m² for hardwood decking
• £100 per m² for composite decking

Extras such as steps, balustrades, or lighting will increase the total cost.

Composite decking vs wood decking

Homeowners often ask whether to choose composite or timber decking:

• Softwood decking: Cheapest upfront, looks natural, but requires annual treatment and has a shorter lifespan
• Hardwood decking: Premium look, more durable, but more expensive to buy and install
• Composite decking: Made from wood fibres and plastic; long lifespan (20–30 years), low maintenance, fade- and rot-resistant. Higher upfront cost, but often better value over time

Our wood vs composite decking cost guide has plenty more information to help you decide.

Decking vs patio: which is better?

Choosing between decking and a patio? It comes down to budget and style:

• Decking is generally cheaper to install, quicker to lay, and better for uneven or sloped gardens
• Patios (stone or paving) last longer, require less upkeep, but often involve higher upfront costs for excavation and materials
• In the UK, decking often costs less initially, but patios can offer lower lifetime maintenance costs

How to install decking
