Garden Decking Cost Calculator

This garden decking cost calculator offers UK homeowners a simple and easy way to estimate how much it may cost to install decking in their garden.

Decking has long been a popular choice for homeowners, offering outdoor seating, dining spaces and level platforms on uneven ground in gardens. The cost of garden decking ranges quite greatly depending on the size of the decking, the materials used for it and how much preparation work is required before installation.

By entering a few key details, you can get a clear estimate and plan your budget before requesting quotes from local decking specialists.

How To Use This Garden Decking Cost Calculator

This calculator is designed to provide a general estimate of what you might expect to pay for installing garden decking, and by providing some simple information, the calculator uses average UK prices to give you an idea of the likely cost, including materials and labour.

Decking Area

Firstly, and perhaps most importantly, enter the length and width of the area you wish to have decking installed on. These measurements will be used to calculate the total area size, which is a massively important factor for pricing. Of course, the larger the area, the more costly the project will be, with the requirement of more materials and longer installation time.

The size of the deck also affects how complex the build will be, as larger decks may need additional structural support, particularly if they are raised above ground level. Even approximate measurements will help produce a useful estimate and give you a better idea of the scale of the project.

Decking Material

From here, you can select the type of decking material you would like to use. Different materials will vary in cost, maintenance requirements and overall durability. There are four main options here - softwood, hardwood, composite and PVC or plastic.

Softwood decking will usually represent the most cost-effective option, and is widely used in UK gardens. Hardwood provides a more premium look and feel, along with a much higher level of durability; you will pay extra for this luxury.

Composite decking, which is a mix of plastic and wood elements, is also popular, providing a great combination of durability and low maintenance. Finally, PVC or plastic decking is designed to resist the elements, but there is a trade-off in terms of aesthetics.

More luxury materials like hardwood and composite will cost more upfront, but generally offer a much longer lifespan, along with little maintenance requirements. So the initial outlay may pay dividends over time.

Selecting your material in the calculator will help adjust the estimate based on typical material and installation costs.

Ground Preparation

The condition of the ground beneath is a crucial aspect of any decking installation and will have an impact on the total cost.

Before the decking is installed, there may be a requirement to level the ground to create a stable base. Often this is achieved with a supporting frame made from timber, and it will be installed to hold the decking boards in place. Weed membranes may also be added to prevent any unwanted growth beneath the decking boards, and drainage improvements may be needed to avoid any buildup of water.

If the ground isn’t level, whether just unbalanced or sloped, additional preparation will be necessary to complete the project properly. This will increase both the cost of materials and the labour time. Ensuring the ground is properly prepared helps improve the durability and lifespan of the decking.

Additional Features

Many homeowners will opt for extra features to improve the appearance and functionality of their decking. Most common features are steps, railings, built-in seating, and even lighting for evening use. Some will integrate pergolas or covered sections for shelter and shade.

Of course, each additional feature will bump up the overall cost as it will increase the materials and the labour required, and in some cases, will make the overall design more complex.

Including these extras in the calculator helps give a more realistic estimate based on the full scope of your project.

Select Your Location

Selecting your location on the calculator is the final option, but it is a very important one.

Labour costs differ quite greatly across the UK, with rates in London and the South East much higher than those in the North and in more rural areas. This is due to the higher demand in larger cities, and a much higher cost of living, and therefore operating costs.

Including your location allows the calculator to provide a more accurate estimate based on typical costs in your area.

Why Do We Include Labour Costs?

Labour accounts for quite a significant portion of the overall cost of any trade project, which is why it is included in the estimate found here.

The installation of decking required a great deal of prior planning, accurate measurements and genuine construction skill. The subframe must be installed so it is level and strong, the decking boards must be securely fitted and aligned, and overall the structure must be strong, stable and safe to use.

Professional installers have the experience and tools needed to complete the work efficiently and to a high standard, and they can also ensure the decking is built to withstand weather conditions and regular use over time.

Including labour costs gives a more complete estimate and reflects the skill involved in building a durable and long-lasting deck.
