Composite fencing is straightforward to install, with a tongue-and-groove fitting mechanism that enables you to stack the boards to reach your desired height.
The boards are designed to fit into existing concrete posts to replace degraded timber fences, saving you installation time and costs. Or you can opt for a complete composite system with matching posts and top caps to create a sleek, clean finish.
Learn more about how to plan and install composite fencing in our guide below.
Planning your installation
Pick where to install the composite fence first. You can fit composite fencing either straight into the ground, or on a concrete base or within existing concrete posts.
Plan your layout
Next, draw your layout with a stringline or chalk. This will help you work out the size of your fence and make sure you're happy with where it’s fitted.
Remember not to cross your boundary line. Dig out your property deeds to double check your boundary if you’re unsure.
Consider the height
In the UK, a fence higher than 6.5ft (around 2m) in your back garden will need planning permission, so it’s advised not to build it any higher.
Use the table below to figure out how many composite fence boards you may need:
| Height (ft) | Composite fence boards | Composite eco fence boards |
| 4 | 8 | 4 |
| 5 | 10 | 5 |
| 6 | 12 | 6 |
If you want to add height to your composite eco fence, you could install a decorative fence topper as long as it doesn’t exceed the maximum height.
Storage and handling
Once your fence boards have been delivered, store them in a dry, clean room to avoid damage. The boards can be stacked on top of each other to save space but the piles shouldn’t be higher than three metres.
Composite fencing is very lightweight making it easy to handle – but always take care when carrying it to prevent injury or damage to the boards. Pick up the boards from the middle, so that the weight is evenly distributed and avoid sliding them on top of one another.
Safety
Composite fencing is simple to install but don’t hesitate to get help from a professional if you’re unsure, especially because incorrect installation impacts your warranty. An experienced tradesperson will be able to fit the fence to your brief, so that it stays stylish and functional for decades.
If you plan to install the composite fence yourself, wear personal protective equipment (PPE) when cutting and installing the boards:
- Heavy duty gloves
- Hard shoes
- Eye goggles
- Face mask
- Long sleeves/trousers
Also make sure that you use any equipment like saws or a drill carefully. Taller fences will need a ladder for installation, so get someone to help you. Avoid leaning the ladder against your fence and make sure it’s on stable/flat ground.
Tip: Use the 4-to-1 rule when positioning your ladder. For every four feet in height, keep the ladder one foot away from your fence.
Installation methods
There’s two ways to install your composite fence:
- Soft ground: Creates a seamless aesthetic but it might get messy as you will need to dig a foundation.
- Concrete posts/footing: Like the picture above, composite boards can be fitted onto concrete posts for stability.
If you’re making use of any existing concrete posts in your back garden, they’ll need to be the correct distance apart.
In the UK, the standard width between posts is 1823mm, which is why Eurocell’s composite fencing is 1.83m in length. It fits neatly between the posts and you won’t need to cut it. Eco fencing is also available in a length of 2.438m.
Tools needed
To install composite fencing, you may need:
- Stringline
- Tape measure
- Hand saw
- Shovel or fencers graft
- Screwdriver
- Electric drill
How to install composite fencing
Install your composite fence during dry weather, especially if it’s into soft ground as the mud can make it difficult to stabilise the fence – plus it’s messier.
Draw your fence line
Start by drawing your fence line.
You can do this using the stringline or chalk, but make sure not to cross over your boundary line. The post should be fitted in your garden, while the fence can sit on the boundary line. But double check your deeds before going ahead.
Dig foundations and fill
If installing the composite fence into soft ground, dig a foundation where you’ve mapped out the fence line. It will need to be between 600mm and 850mm deep.
Where your posts will be fitted, dig holes 600mm deep and pack 50mm of this with broken brick or stone hardcore. Fit your post and continue to add brick/hardcore. The remaining 30cm gap should be filled with concrete and allowed to dry for 24 hours.
Fix your posts
If you’re installing the composite fence on concrete footing, first inspect to check it’s in good condition. It should be at least 15cm thick.
Once you’re satisfied, position the metal posts on the concrete the correct distance apart and keep them square to the edge of the post.
Pre-drill and fix the posts using bolts. A spirit level will tell you whether or not the posts are straight. Slide the fence post over the steel insert, followed by a post skirt to secure it. This can be drilled and secured with a self tapper.
Assemble your fence
Once your base is ready, fix the fence bottom rail and composite boards.
Stack them until you reach your preferred height, keeping a 5mm expansion gap between the board and post.
Finish off by adding the top rail, any fence toppers, and caps to posts.
Always follow the manufacturer’s guidelines when installing your composite fencing. This ensures you don’t break the warranty, which is up to 20 years with Eurocell.
Maintenance and care
A composite fence can last well over 30 years if it’s looked after well. The best part is it’s low maintenance, so you don’t need to paint, stain or seal it for upkeep.
The composite fence will just need cleaning once or twice a year using household products – soft bristled brush, soap like washing up liquid, and water. Avoid using bleach or any other harsh chemicals as this can stain it and ruin the finish. You can also use a jet wash with a fan shape nozzle to clean it.
Investing in a composite fence
With a high tensile strength, composite fences are a reliable option for homeowners, especially those living in cold, windy climates. The fence panels are available in five stylish shades including black, grey and brown to suit your outdoor space. Eurocell’s composite fences are lightweight and durable, and you can choose an eco fencing option too.

FAQs
How much does it cost to install a composite fence?
If you’re a dab hand at DIY, you can save costs by installing your composite fence following the manufacturer’s guidelines. The cost to install a composite fence by a professional tradesperson was around £28 per metre in 2023 but this is subject to factors like your location and project. The cost can also be higher if you have additional needs like groundworks.
Is it hard to install a fence by yourself?
Eurocell’s composite fences have a simple tongue-and-groove fitting mechanism that make installation straightforward. However, if you’re not experienced, hire a tradesperson to fit it correctly for durability and a professional finish.
Do composite fences warp?
Unlike timber, composite fences don’t warp, rot, splinter or crack because they're reinforced with polymer and compressed under high pressure.
