Frequently Asked Questions
Essential need-to-knows when planning a timber decking project.
Decking is an outdoor flooring system usually used as a way of extending functional space beyond the interior of a building. It can be raised or at ground level.
Structurally, it is composed of boards that are precision-machined to a consistent shape and size, which are then laid over a supporting frame to create a level surface.
In residential properties, decking is commonly found in gardens and patios. In commercial environments, it’s often used for high-traffic walkways and leisure spaces.
The most popular material to create decking is timber, due to its natural durability, strength, sustainability and aesthetic appeal. Low-maintenance composite solutions are also widespread.
Start by sweeping away obvious debris and then apply a deck cleaner. There are many great options available at home improvement stores.
You can also create your own cleaning solution using a small amount of dish washing soap with warm water.
Let the solution sit for 10-20 minutes (or however long the product instructions recommend) and then lightly scrub with a stiff brush.
Finally, rinse the deck with a garden hose or low-pressure washer and allow it to completely dry. In winter, this can take a lot longer than anticipated.

It depends on the standard of the decking product you choose and whether you need to hire a professional for installation.
Including only the timber boards:
- Premium hardwood decking, such as iroko or oak: around £60 per m² + VAT
- Mid-range quality softwood decking, such as Thermo-pine: around £35 per m² + VAT
- Lower-end tanalised softwood decking, such as those at DIY stores: around £25 per m² + VAT
- Composite decking: around £40 per m² + VAT
Taking a typical decking area of around 20m², boards in a higher-end species like iroko will cost around £1100 + VAT. In a quality mid-range species like Thermo-Nordic pine, it'll be £640 + VAT. At the lower end, a tanalised softwood deck may run you as little as £300.
Note that the costs above don’t factor in installation costs, which can run £250–£350 per day. For a two-day job, be prepared to pay in the £600 region.
So, for a rough cost estimate that includes both timber boards and installation costs:
- Premium hardwood decking: around £120 per m²
- Mid-range quality softwood decking: around £80 per m²
- Lower-end tanalised softwood decking: around £60 per m²
- Composite decking: around £100 per m²
Given these labour and installation costs will be roughly similar regardless of the quality of timber you choose, we’d recommend a high-end, mid-range or composite option to maximise your investment.
