What we install

Composite Fencing Styles and Colours Across Cardiff

We supply and install composite fencing panels and posts as a complete service: everything sourced, delivered and fitted by us, with no coordination headaches. If you've already bought your panels, we're happy to fit those too. 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.

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.

Complete the look: we can install matching composite driveway or garden gates alongside your composite fencing for a fully coordinated finish.

The basics

Composite Fencing Explained

Composite fencing in the UK is a type of fencing made from a combination of recycled plastics and hardwood fibres. 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, colours and sizes.

Recent installation

Anthracite Composite Fencing with Aluminium Posts, Pontcanna

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 source composite fencing panels and post systems from established suppliers including Eurocell, who operate a trade branch in Cardiff, which means materials are available quickly and locally rather than on extended lead times. We handle all sourcing, delivery and installation as a complete service.

The entire installation, including panels, posts, gravel boards and capping rails, was completed as part of a full garden project alongside new paving, keeping everything under one contractor and one invoice for the customer.

Compared

Composite Fencing vs Wood and PVC

Whilst wooden fencing remains the most popular fence panel for residential properties, there has been tremendous growth in alternative fencing materials. The main ones are plastic, composite and polyvinyl chloride (PVC), which are essentially very similar to each other.

We handle all sourcing and supply as part of our installation service, so 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 have 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, some composites would be ideal.

Plastic is a generic term covering all types of plastics, but the main plastic used for many outdoor products is PVC. It is hard and robust, so ideal for fencing, but much lighter than wooden fencing, especially panels 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!

Pricing guide

How Much Does Composite Fencing Cost in Cardiff?

Composite fencing costs vary depending on the panel height, post system chosen, linear metres required and whether gravel boards or capping rails are included. The figures here are a typical guide across Cardiff; your quote will be based on the exact specification agreed at the site visit.

Composite fencing costs more upfront than timber but requires no treatment or replacement panels for 20 to 25 years, so the total lifetime cost is often comparable to, or lower than, repeated timber maintenance.

Entry level

Eco Composite Fencing

The entry-level composite fencing known as 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 things about eco composite fencing is that its width allows it to be fitted straight into existing concrete posts without the need for a special channel, which adds to the total cost of installation for other composite boards.

Almost 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 come in 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 noticeable on the natural colour, but once stabilised it provides a good lighter background, which works exceptionally well as a more traditional backdrop for plants and shrubs to stand out from.

Keeping costs down

Composite Fencing for Concrete Posts

One of the most cost-effective ways to have composite 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 concrete post, many of the composite panel manufacturers have started to include an 'adapter strip' that can be slotted into the channels of existing concrete posts, which in turn hold the narrower composite panels in place.

From the perspective of the composite manufacturer, whilst they would love you to choose their complete system, including their posts (generally either a composite surround, a steel tube or 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 matching composite posts rather than concrete posts will make a significant difference to the total price of your fence.

However, if you are on a budget and your priority is a low-maintenance composite fence, then installing composite panels into existing concrete posts, or even new concrete posts, will be the most cost-effective option.

Premium range

Premium Composite Garden Fencing

Our premium composite fencing options, whilst coming with perfectly compatible posts, offer more in terms of looks compared with the entry-level eco fence panels. Depending on the option you go for, there will be some embossed composite panels which are grooved to give the look and feel of grained wood. The other option is to go for a smoother textured finish, which looks very neat 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 well.

With 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 or black option and sometimes a shade of brown.

White fencing such as picket fencing will often be uPVC rather than composite, which can look excellent in the right context and surroundings.

FAQs

Frequently Asked Composite Fencing Questions

What is the most popular composite fencing?

Currently, grey composite fencing is the most popular in terms of colour, often dark grey more specifically, with charcoal black becoming a popular choice.

As different composite manufacturers provide slightly different colour options, other shades such as brown are selected, but they are much less popular than grey or black.

As budget is naturally a deciding factor, eco fencing is popular when a good standard of existing concrete posts is in place. Where budget allows, most people choose the premium range, where the composite panels have an embossed wood effect and therefore look much less 'plastic'.

What's the difference between composite and uPVC fencing?

The difference is quite subtle and mostly comes down to what the panels are made of. Composite, as the name implies, is made of more than one material. Most composites use two main materials: plastic and wood. The wood is essentially very fine wood chippings, almost dust, which is added to the plastic in the manufacturing process, and the proportion varies from one manufacturer to another.

Since a pure plastic or uPVC fence panel is made only of PVC, it will commonly be referred to as plastic fencing, although in reality the two are very similar. Both are often made using recycled plastic and wood and, since they last a lot longer once installed, there is a good argument for their overall environmental benefits, as you won't use repeated resources replacing them as much as you would a wooden equivalent.

How do I clean composite fencing?

If you do see dirt and bird droppings accumulate on your composite fencing, they can easily be removed with a gentle jet wash, but this should be on a low setting.

If you don't have a pressure washer, simply cleaning with soapy water and a sponge should do the trick, as dirt does not attach to composite and uPVC in the same way that it does to wood, so maintenance and cleaning are quick and easy.

Do you install composite fencing outside Cardiff?

Yes. We supply and install composite fencing across Cardiff and the surrounding areas, including Penarth, Barry, Dinas Powys, Pontcanna, Canton, Roath, the Vale of Glamorgan, Caerphilly and beyond. We're based in Penarth CF64, so the whole of Cardiff is local to us. Call 029 2271 5157 or request a free quote online and we'll arrange a site visit.

Do you supply the composite fencing panels or do I need to order them?

We usually supply them. Composite fencing is a complete supply and install service: we measure up at the site visit, source the right panels, posts and gravel boards, have them delivered and fit everything, so you don't need to order anything or calculate quantities yourself. If you have already bought panels, we are happy to fit those instead, and we can measure up first to confirm you have enough.

What colours of composite fencing do you install in Cardiff?

Grey is the most popular colour we install, followed by anthracite (a deeper charcoal grey), with wood-effect panels in oak-effect and warm brown tones for period properties. The entry-level eco range comes in grey, walnut brown and a natural colour. Most composite panels lighten by around 10–15% before settling to their final colour, which is worth bearing in mind when choosing.

How much does composite fencing cost in Cardiff?

Composite fencing costs depend on the panel height, post system, linear metres required and whether gravel boards or capping rails are included. As a guide, a full garden boundary of approximately 20 metres would typically start from around £3,400 supply and fit. We always visit and provide a written, itemised quote before any work begins, with no hidden extras.

How long does composite fencing last?

Quality composite fencing from an established manufacturer will typically last 20 to 25 years with minimal maintenance. The panels won't rot, warp, splinter or need treating; an occasional brush down to remove any surface dirt or algae is all that's required. The aluminium post systems we use are designed to the same lifespan. We source from established suppliers including Eurocell, who back their composite products with long-term guarantees.

Can composite fencing be fitted to my existing concrete posts?

In many cases, yes. Some composite panel ranges are designed to fit directly into standard concrete post channels without replacement posts. We assess your existing posts at the site visit and advise honestly on whether re-use is a practical option or whether new aluminium posts would give you a better installation. There is no obligation and no charge for the site visit.
