Installing composite fencing is presented as quick, simple and easier than other materials, but just how easy is it to install? Composite fencing systems come in two types of installation. The installation process will very much depend upon the existing post you have in your home. In most cases, minimal to no tools are required to complete installation and can be done by yourself with little or no experience required. 

Most homeowners tend to have concrete posts in their homes, and for this, you will require our concrete post system. This consists of two U-shaped channels, one aluminium bottom rail, one aluminium top rail, two post caps and ten composite fence panels. 

Gardens with timber posts that are looking to upgrade or replace their current fencing system will need to use our aluminium post system. This system consists of one aluminium post, one aluminium bottom rail, one aluminium top rail and 12 composite fence panels. 

Installation of composite fencing with our aluminium system

Tools required: 

  • A shovel or spade 
  • Wheelbarrow 
  • Skip or Bin 
  • Hammer drill or drill 
  • Circular saw, or hand saw 
  • Poles or lose timber with a clamp to hold any posts in place 
  • Cement 
  • Spirit level 
  • Tape measure 
  • Correct fixing and bolts 
  • Pegs and String line, if required 

Step One – Map Out the Spot 

Mapping out the spot means measuring the length and width of your garden. For a better result, you should draw a rough sketch of where you plan to fit your fence on paper first.  

Also, it is significant to know the topography of the garden space. The topography is important because it lets you know if there are slopes or high grounds in your garden. This will be necessary for ensuring water drains away from your house and if your fence will be installed on them. 

When you have mapped the spot, you can clear it and make sure it is ready for the next step. This means that you should use pegs and ropes to measure a straight line. Also, corners should be noted. 

Step Two – Dig Holes for Posts.  

Before you commence digging the holes, you must confirm that water pipes or any other underground structural facility are not below the fence. To check this, you can reach out to a drainage expert, local council, or local water and gas authority or even double-check with a metal detector over the area in which you plan to dig. It’s also good to double-check you have a permit to build a fence. This will stop any possible future issues which could appear. 

Also, ensure or remove any plants or fixed objects that will create an obstruction or issue during or after installation. This could include small trees and roots. 

Once all is checked, you are set and can start to dig. It’s advisable to dig a hole that is three times the width of your fence post. The whole depth should be at least 500mm. 

Using Steel Base Plates on Concrete 

Posts can also be fitted using a steel base onto concrete. For this option, you will need tools to complete, and it takes around 30 mins and 2 people.

  • A drill bit, e.g., a masonry drill bit 
  • A drill e.g. hammer drill 
  • Concrete fixing bolts 
  • A spirit level 

Place the steel base onto the concrete and mark the holes with a pencil or drill. Once marked using a hammer drill and masonry drill bits, pre-drill the 4 marks in line with the steel base.

the holes are pre-drilled, place the steel base over the holes and use the concrete fixing bolt to fix it into position. Once completed, slide the aluminium post over the top, and you’re ready to slide your composite fence panels into place. 

Step Three – Set Post in the Holes 

After digging the holes, you should set the posts in the centre of the holes. You should determine the height of the fence at this stage. If the height of your fence is 6ft, which is the average used here in the UK, ensure that your post is at least 1.83m in height after being stuck into the ground. Using our 2.4m post, which will be sunken in the ground, the height will be 1.9m, which can then be cut to whatever desired height you require. 

Note that the height of a fence varies according to your needs. If you require a simple partition, you can build a small fence. But if it is the complete privacy that you need, you can build a high fence to the standard of 1.83m or above. Simply cut to your project size at this stage. 

You will need to repeat this process for connections to the next post and ensure you have measured the correct width apart, which average in the UK is 1.8m or 6ft. 

Step Four – Level and Set 

When you are sure that the posts to your projects are the correct size. Please check with a spirit level to ensure they are straight, and then simply cover them with cement. 

You should be certain that the posts are levelled and squared so your fence doesn’t lean or bend. As you can’t hold them together for long periods using scrap timber or poles, clamp them into a fixed position. Then, you should wait for 24 hours so that the cement will dry.  

Step Five – Fix the Bottom Rail 

Once your posts are in a fixed and straight position, double-checking is never a bad piece of advice, so check over with a spirit level and then slide your bottom aluminium rail into place. 

Step Six – Attach the Panels to the Posts 

The next step is attaching the composite fencing panels to the post is the next step. This is very easy to do by sliding the fence panels down the channels already made in the aluminium post. The composite fence panels should connect by tongue and groove so that they interlock. 

 Then, you can repeat the process for all the panels and posts. When you are done, your fence is ready.

Installation Of Composite Fencing with Posts 

  • Please note we do not supply concrete posts and our concrete fencing systems are designed to be fitted into existing concrete posts.
  • As every fencing project is different, if you have posts that have been installed for many years, the concrete may have moved over time requiring cutting of the panels to fit into the posts.
  • Our concrete kits provide 5ft in height as we are expecting your project to already have an existing gravel board along with your existing concrete posts. (The boards alone create 5ft).

Step One – Preparation 

Using our existing concrete post system, you will need to measure the length and width of your fence to ensure that all the sizes are correct and cut if necessary. Once this is checked and confirmed, you can then start to remove the old panels if you already haven’t. 

Step Two – Connection of the U-shaped Channels 

The U-shaped channels should simply slide into the groove of the concrete posts. Cut your U-shaped channel if necessary to fit your project.

Step Three – Sliding bottom rail, Panels and top rail 

Once both U-shaped channels are in position, simply slide the bottom rail making any cuts to size if required. This will then be followed by your composite fence panels, which are connected by tongue and groove and interlocked into place. Repeat this process 10 times until all composite fence panels are in place. Finish off with your top aluminium rail and postcaps. 


Installing composite fencing is easy and can usually be completed without the need for a professional fitter. The material is lightweight, and its easy tongue and groove connection enables the composite fence panels to simply slide into place. The existing fence system is extremely simple and easy to install and has to be our favourite for long-term performance versus upfront cost. Get yourself a sample of the composite fencing panels and start the process of creating your modern, low-maintenance garden.
