How Much is Decking in the UK?

The typical cost of garden decking is around £1,750 for 1 to 2 days of work. This price will vary depending on the materials you choose, the size of the decking, your location, and the duration of the job.

The main material needed is the garden decking itself, which is available in different variations. Understanding the costs of various garden decking materials is crucial for budgeting your project effectively.

The most popular materials include pre-treated softwood, which is the least expensive, with installation costs between £1,080 to £1,320 for 15m².

For something more durable, you may opt for hardwood, which could cost up to £1,840 for 15m² supply and installation.

Another popular material is composite decking. For example, composite wood polymer (WPC) decking costs are around £2,080 to £2,260 for 15m².

PVC plastic is another great option, which is usually priced at around £880 to £1,100 for 15m², offering you an aesthetically pleasing decking material with mould-resistant qualities.

Garden Decking Prices

There are various garden decking costs you need to consider when hiring a professional decking specialist. However, one of the biggest price factors is the size of your garden.

Let's take a look at a small, 15m² garden to begin with:

To compare, let's consider the decking costs associated with a medium-sized garden of around 30m²:

Moving up the sizes, here's what a large garden of around 60m² will typically cost:

Lastly, here's the typical garden decking costs for gardens of 90m² and above:

Garden Decking Supply Cost

The costs of garden decking materials can vary significantly, so it's important to choose the right type for your budget and needs.

If you’re planning to install your decking yourself, you could save a significant amount as you will only have to pay for the cost of the materials.

To help you decide which decking material to choose, take a look at the following supply-only decking costs:

Here are some of the most common decking materials you'll come across during your project:

Labour Cost to Lay Decking & Timescales

Now, let's take a look at decking installation costs in 2025.

The average decking installation usually takes around 1 to 2 days to complete.

However, this will vary depending on the size of the garden, the materials used, and how many tradesmen are working on the job. A small garden of around 15m² may only take 1 day for 2 or more tradesmen to complete the job.

On the other hand, a decking installation which requires a significant amount of excavation — including removal of weeds, shrubs, trees, existing decking, and more — could take more than 4 days, especially for a large landscape.

If you don’t feel confident in installing DIY decking, your best bet is to call in a professional who will make sure that the job is done properly.

Additional Garden Decking Costs

There are plenty of other material costs you need to consider when having garden decking installed, although this will depend on your preferences.

Garden Fence Replacement

If your garden fence has seen better days, you can have your garden fence repaired for £110 per metre of fencing material.

Garden Maintenance

Garden maintenance costs start at £220 per day for jobs like grass cutting, weeding, watering, hedge trimming, and plant pruning.

If you need your garden landscaped before starting work on your decking, you may need to consider hiring a garden leveller beforehand. Garden levelling costs can range from £1,100 to £7,700 and above depending on the complexity of the job, and scope of work.

Garden Waste Removal

Some of these jobs may necessitate a waste removal service. Garden waste removal costs around £220, but prices vary depending on the exact type of garden waste, and whether or not it's considered hazardous waste to dispose of.

Costs of Garden Decking Maintenance and Cleaning

When maintaining and cleaning your decking, it is important to understand the level of maintenance required for different materials, including:

Softwood and Hardwood

This requires yearly maintenance, including sanding, staining, and sealing, which would cost around £11 per m².

You should also try to keep on top of it by cleaning it with a decking cleaner, which costs around £6.60 to £16.50. This will help to keep the wood’s natural colour, making it appear brand new.

IPE wood

This type of wood is low-maintenance, so it would only require you to oil it once a year. The cost of decking oil is around £33 for five litres.

Composite, PVC, and Trex

Composite, PVC, and Trex require a simple cleaning procedure which involves soap, hot water and a soft-bristle brush. You should try to clean it a few times a year, including after installation and once or twice in spring and autumn.

The only cost you may incur is replacement costs, as, unfortunately, composite cannot be sanded to remove dents. Instead, it must be replaced, which could cost up to £72 per m².

You should also consider additional repair costs, such as:

• Damaged deck boards - £1,050
• Loose stairs - £110 to £275
• Mould and rot - £165 to £495
• Stain and seal - £7.70 per m²

These repairs can be conducted by you or a professional, although for the latter, you will also need to consider the labour cost, which is usually around £330 for repairs.

What Impacts the Garden Decking Installation Costs?

When evaluating garden decking costs, there are various things you need to consider.

Condition of Garden Terrain

First, you should examine the condition of your terrain and determine whether it is flat, as sloping or difficult terrain will significantly impact the cost.

Garden Size

The size of your garden will also have an impact on the price, as the larger your garden is, the more materials you will need.

Larger decking will also take much longer, resulting in increased labour costs, as professional installers usually charge an average of £36 per m².

Type of Decking

The decking material you choose will also affect your project costs, as some decking materials are more expensive than others.

If you have a low budget in mind, you may want to stick to timber decking, which typically costs around £1,100 to £1,650 to install.

However, if you are thinking long-term, you may be better off with composite decking, which is more expensive, with prices up to £10,000 for larger gardens.

If you already have decking in your garden that needs to be replaced, you will also need to factor in the replacement costs. Spot replacements cost around £330, however, a full replacement can cost £4,400 or more.

Planning and Installing Garden Decking

Planning your garden deck is a crucial step in ensuring that your outdoor space is functional, safe, and aesthetically pleasing. Before you begin, consider the following:

• Size and shape of your garden: Measure your garden to determine the available space for your deck. Consider the layout and how the deck will fit into your overall garden design.
• Type of decking material: Decide whether you want to use softwood, hardwood, composite, or PVC decking. Each material has pros and cons, so choose one that fits your needs and budget.
• Budget for the project: Set a budget for your garden decking project, including materials, labour, and any additional features like railings or lighting.
• Purpose of the deck: Consider how you plan to use the deck. Will it be a space for dining, lounging, entertaining, or a combination of these activities?
• Local building regulations and planning permissions: Check with your local authority to ensure you comply with any building regulations and obtain necessary planning permissions.

Garden Decking Building Permissions

If you're planning on building a DIY deck, you should note that building regulations can be an issue - even with small decks.

It's always worth checking with your local authority before you spend any money on decking or begin any construction.

If you are going to build a substantial deck, keep neighbours informed and on-side from the start and be prepared to alter your building plans if they object.

Building regulations for decking only require you to apply for planning permission if your decking is over 30cm high. You may also need to apply if your decking or other extensions take up more than half of your garden space, as this is classed as a major alteration.

If you do fall into the above categories, then you should expect to pay around £265 for planning permission. If you fail to pay this, you will be fined, and you may also face issues with your local council or neighbours.

How to Lay Decking

Installing garden decking can be straightforward for those comfortable with DIY, but if your garden is sloped or it's your first DIY project, it can be tricky.

The installation process for garden decking typically involves the following steps:

• Preparation: Clear the area of debris, vegetation, and obstructions. Ensure the ground is level and stable.
• Groundwork: Lay a foundation of concrete or gravel to provide a stable base for the deck. This step is crucial for preventing future issues, such as sinking or shifting.
• Framing: Construct the frame of the deck using joists and beams. Ensure the frame is level and securely anchored to the ground.
• Decking: Install the decking boards, ensuring they are securely fastened to the frame. Leave a small gap between boards to allow for expansion and drainage.
• Railings and balustrades: Install railings and balustrades to provide safety and support. Choose materials that complement your decking and overall garden design.
• Finishing touches: Add decking screws, nails, and other finishing elements to complete the deck. Consider adding features like lighting, planters, or seating to enhance the functionality and aesthetics of your garden deck.

Can I DIY Decking?

While it’s possible to DIY decking, it’s not recommended unless you have extensive carpentry experience and knowledge of local building regulations. Decking installation requires specialised skills and equipment, and mistakes can lead to safety hazards and costly repairs.

However, if you’re determined to DIY your decking, here are some tips to consider:

• Start with a small, simple project: Gain experience and build confidence by starting with a smaller, less complex decking project.
• Research and follow local building codes and regulations: Ensure your project complies with all relevant building codes and regulations to avoid fines and safety issues.
• Choose a decking material that is easy to work with: Composite or PVC decking can be easier to handle and install compared to hardwood or softwood.
• Invest in quality tools and equipment: Accurate and safe installation requires the right tools. Invest in high-quality tools to make the job easier and more precise.
• Consider enlisting the help of a friend or family member with carpentry experience: Having an extra pair of hands and some additional expertise can make the project go more smoothly.

Remember, DIY decking can be a cost-effective option, but it’s essential to prioritise safety and quality to avoid costly mistakes and potential hazards. If you’re unsure about any aspect of the project, it’s always best to consult with a professional.

Garden Decking Removal Costs

Removing your old garden decking will cost around £110 to £550 for 2 to 7 hours.

While this may seem expensive, it's worth it to ensure the job is done quickly and correctly.
