What we install
Composite fencing styles & colours across Cardiff
We supply and install composite fencing panels and posts as a complete service — everything sourced, delivered and fitted by us. No part-supplies, no customer-sourced panels, no coordination headaches. Here are the main options we install across Cardiff.
Grey Composite Fencing
Mid grey composite panels are our most popular colour across Cardiff — particularly in Pontcanna, Canton, Roath and the Vale. The cooler tone sits naturally with rendered and brick properties and holds its colour well over time. Available in a range of heights to suit your boundary requirements.
Anthracite Grey Composite Fencing
A deeper charcoal tone that makes a strong statement on contemporary Cardiff properties — particularly effective alongside aluminium posts and matching composite or metal gates. Increasingly popular on newer builds across the Vale of Glamorgan and Penarth.
Wood-Effect Composite Fencing
Composite panels that replicate the grain and warmth of natural timber without any of the maintenance. Popular for period properties and gardens where a cooler grey tone would feel at odds with the character of the house. Available in oak-effect and warm brown tones.
Composite Fencing to Replace Existing Posts
If your existing concrete posts are structurally sound, some composite panel ranges can be fitted directly into the existing post channels without replacement. We assess post condition at the site visit and advise honestly on whether re-use is viable or whether new posts would give a better result.

Composite Fencing Explained
Composite fencing in the UK is a type of fencing made from a combination of recycled plastics and hardwood fibers. This material is highly durable, low maintenance, and environmentally friendly. It is a popular choice for fencing in the UK due to its long lifespan, resistance to rot and insect infestation, and range of design options. Composite fencing can be used for residential or commercial properties and is available in a range of styles, colors, and sizes.
Composite fencing vs wood/PVC
Whilst wooden fencing remains the most popular fence panel for residential properties there has been tremendous growth in alternative fencing materials other than wood. The main ones being plastic, composite and Polyvinyl Chloride (PVC), which essentially are very similar to each other and we can access a number of these from merchants in the Cardiff area but we are aware than many companies manufacturing these fence panels will have these available to order online.
We handle all sourcing and supply as part of our installation service — you don't need to order panels separately or calculate quantities. We measure up, source the correct materials and fit everything as a complete job.
Some composite and PVC fencing panels are made to replicate wood but has the benefit of requiring no treatment with many coming with guarantees of twenty years. There are also some which can simply be fitted into existing concrete posts so if your wooden panels need replacing but your posts do not, then some composites would be ideal.
Plastic is a generic term encapsulating all types of plastics but the main specific plastic used for many outdoor products is PVC. It it hard and robust, so ideal for fencing but much lighter in weight than wooden fencing - especially those that are hollow with internal webbing to give extra strength and rigidity. Once fitted you'll barely need to do anything with them for the next decade or two!
Recent installation
Anthracite composite fencing with aluminium posts — Pontcanna, Cardiff
This recent Pontcanna installation shows anthracite grey composite panels fitted with matching powder-coated aluminium posts — one of the most popular combinations we install across Cardiff. The aluminium post system gives a cleaner, more contemporary finish than concrete posts and is the preferred specification for most composite fencing jobs we carry out.

We handle all sourcing, delivery and installation as a complete service.

Eco Composite Fencing
The entry level composite fencing known at the eco composite fencing range provides a great way to move away from wood and install a low maintenance long lasting composite fence.
One of the excellent factors about eco composite fencing is that it's width allows it to to be fitted straight into existing concrete posts without the need for a special channel which add to the total cost of installation for other composite boards.
Emost all composite boards come in 6ft lengths and will be either 6" or 12" high. In the case of the eco fence panels these are 12" high, so a 6ft fence needs 6 panels stacked on top of each other. The height of the fence needs to go up in 12"increments as the boards are not designed to be cut horizontally.
The eco composite fence panels com ing a grey, walnut brown and a natural colour. What also needs to be taken into consideration for most composite fence panels is that there will be a level of lightening in colour before a final stable uniform colour is achieved. This is normally around 10-15% lighter than when first installed. This is most noticable on the natural colour but once stabilised it provides a good lighter background which works exceptionally well to provide a more traditional background for plants and scrubs to stand out from.

Composite Fencing for Concrete Posts
One of the most cost effective ways to have compopsite fencing in your garden is to install composite fence panels into existing concrete posts. Whilst only a few composite fence panels will slot straight into an existing composite post many of the composite panel manufacturers have started to include a 'adapter strip' than can be slotted into the channels of existing concrete posts which in tern then hold the narrower composite panels in place. From th eperspective of the composite manufacturer whilst they would love yuo to choose their complete system to include their posts which will either generally be either a composite surround of a steel tube of a full aluminium post they are realising that it is better to at least sell their panels rather than sell nothing at all. If you are having a long stretch of fencing then having mathcing composite posts rather than concrete posts will make a significant difference on the total price of your fence.
However, if you have a budget an your priority is to have a low maintenance composite fence then installing composite panels in to existing concrete - or even new concrete posts will the most cost effective option.
Premium Composite Garden Fencing
Our premium composite fencing options whilst coming with perfectly compatible posts offers more in terms of aesthetics compared to the entry level eco fence panels. Depending on the option you go for ther will be some embossed composite panels which are grooved to give the look and feel of a grained wood. The other option is to go for a smoother textured finish which looks very neat and modern and would fit a contemporary modern garden design. As part of a wider landscaping project composite fencing can provide an exceptionally good background from which other landscaping features will stand out out well.
Will premium composite fence panels there is generally a more limited choice of colours. With almost every manufacturer there will be a grey of some sort, a charcoal/black option and sometime a shade of brown.
White fencing such as picked fencing will often be UPVC rather than composite, which can look excellent in the right context and surroundings.
