How much does installing decking cost?

  • Materials - Including concrete/Weed Mat for the base, Joists, andScrews for the structure, and of course all the Decking Boards, Trims, and flashings. Material prices can differ depending on the range of Boards you purchase, Timber, Composite, Plastic, and PVC Decking Boards all differ in cost, find out more about the cost differences here.
  • Labour - If you're employing someone to install your garden decking, prices will vary depending on the design, square metres of decking, Decking Material, and garden location.
  • Maintenance - While Composite Decking does not require a heavy amount of maintenance, Decking Cleaning and Reviver is an additional cost to keep in mind. Timber Decking, however, requires sanding, painting, and varnishing regularly which should be accounted for in the initial decking plans.

For the average UK garden, which is between 100 and 180 square metres the cost of Composite Decking Materials could vary and could cost roughly £80 per square meter for installation costs and post-maintenance.

Don't forget if you plan on adding Decking to more than 50% of your garden (or if you have existing buildings which with the decking will equal 50% of your garden space) then you will need planning permission.

Adding Decking to your garden has a plethora of advantages including:

  • Creating a large, spacious area to entertain friends
  • Decks are easy to maintain, creating a low-maintenance garden
  • Encourages life outside, as an additional living space to your home
  • Could reduce the amount of mud, and debris in your house and garden
  • Could increase your property's value.

Average garden decking costs

The average UK decking size is roughly 15sqm for a small deck, 30sqm for a medium, and 60sqm for a large decking area.

So, you've decided to add decking to your garden, you know the size of your garden, and roughly how many boards you will need. Now all you need to do is find out where the best-priced, Timber Decking, Composite Decking, PVC Decking, and other Decking materials can be sourced.

Decking cost per m2 and the price of Decking also varies depending on the brand you decide on. Below is the average cost of Composite Boards per square metre of the average UK garden.

To figure out the size of your decking area and the approximate cost of Boards, simply measure the length and width of your proposed deck area (in metres) and multiply them together. Next, multiply your area by the decking cost per m2. Finally, the answer will give you an approximate cost for your decking. This doesn’t take into account the cost of trims, joists, or fittings, as these are dependent on your site conditions. But, it’s a start, or, alternatively, Cladco Decking Calculator will estimate the costs for you here.

Garden Decking Costs will vary for many reasons, some of which being:

  • The price of manual labour for installation
  • The price of the raw materials, Decking Boards, Fixings and the Frame
  • Location, typically installation costs can increase by up to 20% if you live in or around London.
  • The Ground you wish you lay your decking on. A flat or level ground requires less work than a garden with an unlevel surface, the cost of levelling out the ground can increase the overall decking price
  • Base, do you wish to have a concert base or a Weed Mat base?
  • Height of your Decking - Do you need planning permission or a tall frame?

Labour costs and time frames

When going to install your Decking, or looking for installers, be sure to know the correct size of your proposed area, this will assist in finding the correct decking installation cost.

To find out the square metre of your allotted space, simply measure both the width and the length and multiply together. Once you have this you can approach installers with the size and design of your Decking area.

The average cost and time to install decking can vary depending on certain variants, the height of decking, materials are chosen, and how the frame would fit the ground. If the ground needs clearing of any shrubs, trees, roots, or stones. If the decking is at ground level, the ground will need to be levelled off, if the Deck is going to be at a height, then you may need planning permission, as well as a stable substructure, needs to be built beneath the Deck.

On average most professional installers are able to install an average-sized per square metres designed Deck, within 2-3 working days, depending on the condition of your area. However, if you are going to build your Deck yourself, as a DIY project, the time frame may differ depending on how many years of experience you have, what time you have available, etc. When fixing your own deck, it is important to always follow the supplier's installation guides, to ensure the warranty of your products is not put at risk.

Additional Deck Material Costs

Is Decking expensive? Unfortunately, Decking Projects can be full of surprising purchases if not properly budgets. As it is not just the Decking Boards you will need to purchase, Joists, Screws, Weed Mats, and Trims also need to be considered, which is something people often forget, making their project potentially go over budget.

Additions include:

  • Joists/Battens - Hardwood, Softwood, Composite, and PVC Decking Boards require sturdy substructure and the support of Joists.
  • Balustrades - Added as a sturdy, durable addition for both safety and design
  • Trims - Corner and Skirting Trims can be used as Fascia boards to hide the structure and joists beneath, as well as adding final details to the edges of your Deck.
  • Fixings and Screws - Make sure you have the correct screws and fixings for your Deck. Hardwood and Timber Decks can be fixed used Traditional Timber Wood Screws, however, Composite Boards should be fixed using Composite Screws.
  • Weed Mat - If you are wanting to install your Deck in your garden, without first laying a concrete base, it is advised a membrane or material is put down to ensure no weeds or vegetation will grow up beneath your Deck and penetrate through the gaps. A Weed Mat prevents any weeds from growing, while still allowing water and nutrients to reach the soil below.

Below we have compared the costs of the additional materials across Decking companies, please note additions will only be compatible with the same companies Decking Boards. Boards bought from Cladco will not be able to be finished with Trims purchased from Dino Decking.

Other Factors of garden decking installation costs to consider

Now you have your Decking Boards, Joists, Fixings, and other accessories sorted, it's time to think about any additional costs you may need to take into account when installing your Decking. While installation should only take 2-3 days on average for a professional to fit, if any additional steps need to be taken, time frames may increase.

  • Skip - If you are having to level out your gardens surface the additional cost of a skip may be necessary
  • Delivery - If you are unable to collect your Decking Materials, the cost of delivery may need to be factored into your budget.
  • Sander - If you have purchased any Timber wood for your decking project, you may need to sand, varnish, and stain it before installing it to your desired look.
  • Varnish - Timber often needs to be varnished, or sealed once installed to ensure the Boards stay looking high-quality for years to come.
  • Cleaner - Both Timber and Composite Decks may get dirty while being built, cleaners can be purchased once the Deck has been built, for a perfect finish. This can be used for many years too.
  • Concrete - If you are wanting to install your deck on a concrete base, purchasing and paying for that concrete to be installed correctly is an additional cost to factor in.
  • Landscaping - If you are wanting a ground-level garden deck, the deck should be installed on a flat, level surface. Landscaping and levelling out of your garden may be required before the install can begin.

The cost of aftercare and maintenance should also be taken into consideration when planning a decking area. Composite Decking, unlike Timber, does not need much post-installation aftercare. Cladco Composite Decking has a ten-year guarantee, and should not rot, warp, splinter, fade, or stain. The Boards may simply need the occasional clean. Timber Decking Boards, however, will need maintenance for the years that it is installed, wood is also susceptible to staining, splitting, warping, rotting, and fading.
