Who We Are & What We Do
Composite Decking World Ltd is based in Upminster, Essex (RM14). We are a specialist composite decking supplier and installer - not a general landscaper who fits decking as a sideline. Composite decking is what we do, and it is all we do.
We supply our own range of composite decking boards in five finishes, all carrying a 10-year guarantee, at the lowest prices in the UK market. For Essex customers, we combine that supply with a professional installation service: one team, one point of contact, and no need to source a separate fitter.
Supply & Install Under One Roof
No coordination between supplier and fitter. We supply the boards, accessories and fixings - then our team installs them. One quote covers everything. The guarantee on the boards covers the product you're standing on.
We work on projects of all sizes across Essex - from a modest garden deck in Hornchurch to a large commercial terrace in Chelmsford. Whether you're replacing ageing timber decking, creating a new outdoor space from scratch, or adding a deck to a new build, we can handle it.

Our Installation Process: From First Call to Finished Deck
We follow a clear, structured process on every project. No surprises, no scope creep, no corners cut on preparation.
-
1Free consultation and site assessment. We start with a conversation - in person or by phone - to understand your project. For larger or more complex decks, we carry out a site visit to assess ground conditions, access, drainage and the existing substrate. This shapes the quote.
-
2Free, itemised quote. You receive a clear written quote covering all materials and labour. We explain what's included, why, and what the alternatives are. No pressure. No obligation.
-
3Board and finish selection. We walk you through our five board finishes - Teak, Chocolate, Silver Grey, Graphite Grey, and Charcoal Black. If you haven't already received your free sample box, we arrange that before you commit, so you can assess the colour in your garden's natural light.
-
4Subframe preparation. A structurally sound subframe is the foundation of every well-built composite deck. We build from pressure-treated timber or composite joists (the longer-lasting choice), correctly spaced to the manufacturer's specification for your board type. Ground-level decks receive a weed-suppressant membrane and drainage provision.
-
5Board installation with hidden clip fixings. Grooved boards are fitted using a hidden clip system that engages in the board profile and fastens to the joist, maintaining the correct board-to-board expansion gap automatically. The result is a seamless, screw-free surface. Expansion gaps at perimeters and fixed structures are set precisely to the manufacturer's specification - the step that most DIY and inexperienced installations get wrong.
-
6Edging, trims, and finishing. Fascia boards, edge trims and end caps are fitted in a matching finish, giving the deck a clean, considered perimeter. Steps, balustrades and post bases are included where specified in the quote.
-
7Final walkthrough and handover. Before we leave, we walk through the finished deck with you, explain the minimal maintenance it needs, and confirm the guarantee documentation. Site is left clear and tidy.
The Boards We Install
We install our own composite decking range - boards we supply, guarantee, and stand behind completely. They are available in five finishes, with embossed wood-grain textures, UV stabilisers and a low-porosity surface that resists staining, algae, and fading.
All boards are manufactured from a blend of recycled wood fibres and recycled plastic, and are designed to perform in the UK climate - resistant to moisture, frost damage, UV fading, and the algae and mould growth that make timber decking in shaded or damp Essex gardens so problematic.
| Board Property | CDW Composite Boards | Pressure-Treated Softwood |
|---|---|---|
| Annual maintenance | None required - occasional wash only | Sanding, staining and sealing every 1–2 years |
| Expected lifespan | 25+ years | 10–15 years with maintenance |
| Rot & moisture resistance | Excellent | Poor without treatment; deteriorates in damp gardens |
| Slip resistance when wet | Textured surface - good | Smooth grain becomes hazardous when wet |
| Splinter risk | None | Increases as timber ages and dries |
| Guarantee | 10 years | Typically none |
Not sure which finish suits your garden? Order a free sample box - all five finishes sent direct to your door. Colours look meaningfully different on screen versus in natural daylight in your specific garden, so we strongly recommend assessing physical samples before choosing.
Areas We Cover for Composite Decking Installation in Essex
Based in Upminster (RM14), we install composite decking throughout Essex - from the Thames estuary towns in the south to Colchester and Harlow in the north, and across the county east to west.
Residential Composite Decking Installation in Essex
The majority of our Essex installations are for homeowners - decking a garden, replacing an old wooden deck, or adding an outdoor dining or entertaining space. Here is what residential customers typically get from our service.
Common Residential Scenarios We Work On
| Scenario | What We Do |
|---|---|
| Timber deck replacement | Old softwood decking that is rotting, splintering, or past the point of reasonable maintenance. We remove the existing structure, prepare the substrate, and install a composite deck that won't need replacing for a generation. |
| New deck on an existing garden | A blank patio or lawn area transformed into a usable outdoor living space for dining, relaxing, or entertaining. We design the layout, build the subframe, and fit the boards to a clean finish. |
| Extension or bifold door terrace | Continuation of interior living space into the garden - popular with rear kitchen-diner extensions. We match board direction and level to the interior floor finish where possible. |
| Sloping or uneven gardens | Raised or multi-level decks that use the site topography to create tiered outdoor spaces. We design and build the subframe to deliver a level, safe surface regardless of ground conditions. |
| Pool surrounds and damp areas | Composite decking is the right choice around pools and in permanently damp or shaded gardens where timber is most vulnerable to rot and slipping hazards. Our boards are slip-resistant and moisture-resistant by design. |

Commercial Composite Decking Installation in Essex
Composite decking is an excellent material choice for commercial outdoor spaces - it handles high footfall, requires minimal ongoing maintenance, and maintains a professional appearance across large areas without the annual cost of treating or re-boarding timber.
Commercial Settings We Work In
Pubs, Bars & Restaurants
Beer garden terraces, outdoor dining areas and smoking areas. Composite decking handles the heavy footfall, weather exposure and occasional spillage of a commercial hospitality environment without the maintenance overhead of timber - which in a licensed premises setting typically means expensive annual contractor visits to sand, re-stain and re-seal.
Hotels, Holiday Lets & B&Bs
Outdoor terrace areas, poolside decking and garden platforms for accommodation businesses. Composite decking's low-maintenance requirements are particularly valuable for hospitality operators who cannot afford the downtime of annual sanding and sealing, and who need a surface that remains presentable to guests year-round.
Schools, Nurseries & Public Spaces
Outdoor classroom areas, playground decking and communal seating platforms. The splinter-free, slip-resistant surface of composite decking makes it a safe and appropriate choice for settings where children are the primary users. Our boards carry no toxic preservatives and require no chemical treatment during their service life.
Offices & Commercial Properties
Roof terraces, staff breakout areas, and outdoor facilities for commercial office occupiers. Composite decking's durability and ease of maintenance makes it a practical specification for commercial property managers.
Commercial projects receive the same standard of installation, the same board range, and the same 10-year product guarantee as our residential work. Contact us to discuss your commercial project requirements.

- Shorter guarantees (some competitors offer 5 years vs our 10)
Composite Decking Installation Costs in Essex
Installation cost is the question every homeowner asks first, and it deserves a direct answer - even if a precise figure always requires a site-specific quote.
| Cost Component | What to Expect |
|---|---|
| Board supply | From £16.50/m² for CDW composite boards (all five finishes) |
| Subframe materials | Pressure-treated timber or composite joists; cost varies with deck size and height |
| Fixings, clips & edging | Hidden clips, fascia boards, edge trims and end caps; included in our full quote |
| Labour (installation) | Depends on deck size, complexity, ground conditions and access; quoted upfront |
| Waste removal | Included in full supply-and-install quotes |
As a guide, a straightforward ground-level residential deck on a prepared substrate costs meaningfully less than a multi-level elevated deck with complex angles, steps and balustrades. That spread is why a site visit or detailed brief is needed to give a number with confidence.
What we can say is that our board pricing is the most competitive available at £16.50/m², and that composite decking - when considered over its 25+ year service life - is typically more cost-effective than timber once ongoing maintenance and likely re-boarding are factored in.
