Composite Decking Installation in London

Composite Decking Installation in London

If you are looking for composite decking near me — or more precisely, for composite decking installation in London that is actually done well — you are in the right place. We are London Decking Specialists, a team of master carpenters who supply and fit composite decking boards across London and the surrounding boroughs. From a modest back garden in Clapham to a roof terrace in Kensington, we have fitted composite decking in some of the most demanding conditions London has to offer.

Composite decking has become the first choice for many London homeowners, and it is not hard to see why. Unlike natural timber, composite boards require virtually no maintenance, hold their colour year after year, and are designed to handle whatever the British climate throws at them — which is a more relevant selling point than it might sound. No annual oiling, no re-staining, no splinters. Just a good-looking, long-lasting deck that does exactly what it is supposed to do.

We take the same approach to composite decking as we do to every job: honest advice about materials, careful preparation of the sub-frame, and a professional finish that holds up over time. We are not going to recommend the most expensive boards if they are not right for your garden, and we are not going to cut corners on the build to hit a lower price. If you want composite decking done properly in London, we would be glad to give you a free, no-obligation quote.

Finished composite decking in a London garden — grey boards with outdoor seating area

The Low-Maintenance Choice for London Gardens

Composite boards require virtually no maintenance — no annual oiling, no re-staining, no splinters. They hold their colour year after year and are engineered to handle whatever the British climate throws at them.

We work with all the leading brands — Millboard, NeoTimber, Cladco and Trex — and will recommend whichever suits your garden, style and budget. We have no tie to any manufacturer.

Why Composite

Non-Slip & Low Maintenance Composite Decking

Low Maintenance

No oiling, no staining, no annual treatment. A brush down and occasional wash is all it takes to keep composite boards looking good year after year.

Non-Slip Surface

Anti-slip composite decking features a textured surface engineered for grip in wet conditions. A practical advantage in a country where dry Saturdays are not guaranteed.

All-Weather Performance

Engineered to resist UV fading, moisture, frost and temperature variation. Composite decking boards are designed for outdoor conditions — including British ones.

Adds Real Value

A well-built composite deck adds usable outdoor space and lasting kerb appeal. London buyers notice quality — and a properly built deck does not go unnoticed.

Colour Options

Grey & Black Composite Decking

One of the most common questions we get from clients is about colour — and it is a fair question, because composite decking boards come in a far wider range of shades than most people expect. Here is an honest guide to the main options.

Grey Composite Decking

Grey composite decking is currently the most popular choice across London, and it is easy to understand why. The clean, contemporary look works well with the brick and render of most London homes, and grey boards age gracefully. From light ash grey through to deeper slate tones, there is a shade for every garden. Grey sits comfortably with both modern garden furniture and more traditional planting.

Black & Anthracite Composite Decking

Black and anthracite composite decking has grown significantly in demand over recent years, particularly in more modern homes and on roof terraces. The deeper tones create a striking contrast with greenery and light-coloured render. Anthracite composite decking in particular sits in a sweet spot between dramatic and understated — bold enough to make an impression, subtle enough to work with most garden planting.

Natural & Wood Effect Composite Decking

Wood effect composite decking suits those who want the low-maintenance benefits of composite but prefer the warmth of a timber aesthetic. Modern boards in natural tones are genuinely convincing — the grain textures and colour variation have come a long way from the early boards, which could look somewhat artificial. These work particularly well in traditional London gardens with established planting.

Whatever colour you choose, we will help you make the right decision for your specific garden, home and light conditions. A shade that looks perfect in a showroom can read quite differently on a north-facing garden in November — and we will tell you that before you commit.

The Material

What Is Composite Decking?

Composite decking boards are made from a blend of wood fibre and recycled plastic — typically polyethylene or PVC — mixed with binders and UV stabilisers. The result is a board that looks like timber, feels reasonably similar underfoot, but behaves quite differently in terms of maintenance and longevity.

The core technology has improved significantly over the past decade. Early composite decking had a reputation for fading, warping and looking artificial. Modern boards — particularly from the better manufacturers — are a different product entirely. Hollow and solid core options offer different weights and price points; grooved and smooth surfaces suit different use cases; and a range of finishes from brushed to enhanced grain provides genuine variety.

What composite decking is not is a complete substitute for the feel and character of real hardwood or softwood. If that natural warmth and grain variation matters to you, timber decking may be the better choice. We are happy to discuss both options honestly — there is no right answer, only the right answer for your garden.

Pricing Guide

Composite Decking Costs in London

Let us be straightforward about composite decking prices in London — because pricing transparency is something we think everyone deserves, and vague answers are not helpful when you are planning a project.

Composite decking costs depend on several factors: the size of the deck, the boards you choose, the complexity of the sub-frame (whether you are building on a flat surface, concrete, a slope or a first floor), and any additional elements such as stairs, balustrades or integrated lighting.

Entry Level

£100–140/m²

Solid composite boards, standard installation

Mid Range

£140–200/m²

Cladco, NeoTimber and equivalent quality boards

Premium

£200–300+/m²

Millboard and top-tier boards with enhanced warranty

These are fully installed costs — they include materials, the sub-frame, fixings and labour. A typical London garden deck of 20–30m² will come to somewhere between £3,000 and £7,000 depending on specification, with premium boards and complex sub-frames at the higher end.

A note on composite decking prices per m²: what looks like a more affordable option upfront can become less competitive once you account for the sub-frame and fixings, which make up a significant portion of the total cost. We give you a detailed, itemised quote so you know exactly what you are paying for — composite decking cost per m² and everything else.

We would rather give you an honest number than a low estimate that comes with surprises. If your budget has a fixed limit, we will tell you what is achievable within it — and if it is not achievable, we will tell you that too.

How We Work

Our Installation Process

We believe a good relationship with a client starts before the first board goes down. Here is how we approach every composite decking project.

01

Discovery

We visit your garden, understand exactly what you are looking for, and give you our honest assessment of what is achievable within your space and budget.

02

Design

We help you choose the right boards, finish, colour and sub-frame approach — along with any additional features such as steps, balustrades or integrated lighting.

03

Materials

We source your chosen composite boards and all supporting materials — frame timber or steel, fixings, fascias and edging — so nothing is left to chance.

04

Preparation

Proper sub-frame preparation is the foundation of a long-lasting composite deck. We take our time here — a level, well-built frame is not optional.

05

Installation

Our master carpenters fit the composite boards to a professional finish, with clean lines, consistent gaps and neat edging throughout.

06

Sign-Off

We clean up fully, walk you through the completed work, hand over care guidance for your boards and only leave when you are satisfied.

Brands We Install

Composite Decking Brands We Work With

We work with all the main composite decking brands and can source and install whichever you prefer. We have no tie to any single manufacturer — our recommendation will always be based on what is right for your project, not what is convenient for us.

Millboard

Widely regarded as the premium option. Exceptional grain texture, outstanding durability and a 25-year manufacturer guarantee. Not the most affordable composite decking — but one of the best.

NeoTimber

A strong mid-range board with good colour range and hollow-core options that keep weight down — well suited to balconies and roof terraces where load matters.

Cladco

A reliable, popular choice for those who want quality boards at competitive composite decking prices per m². Cladco offer solid performance without the premium price tag.

Trex

The global market leader in composite decking, with a wide range at various price points. A proven product with strong performance across the board.

Sustainability

Eco-Friendly Composite Decking

One of the less obvious reasons to choose composite decking is its environmental credentials — or at least, the better boards have good ones. Most composite decking is made partly from recycled wood fibre (often sawmill waste) and recycled plastic reclaimed from post-consumer sources, giving materials a use that would otherwise end in landfill.

There is also the question of longevity. A composite deck that lasts 25–30 years before needing replacement is, in most cases, a more sustainable outcome than a timber deck that requires ongoing treatment, may need boards replacing after a decade, and eventually ends up as waste. Less frequent replacement means less material consumed over the life of your garden.

We are not going to overstate this — no outdoor material is entirely without environmental cost. But if sustainability matters to you, composite decking from a responsible manufacturer is a reasonable choice, and we are happy to advise on which brands have the strongest credentials.

Client Reviews

What Our Clients Say

We had composite decking fitted across our south-facing terrace and the difference is remarkable. The team were professional, clean and gave us really honest advice about which boards to choose. We went with grey composite and it looks exactly right for the house.

Sarah T.

Wandsworth, SW18

I had a quote from another company that came with a very vague specification. London Decking Specialists gave me a proper itemised breakdown, explained exactly what the sub-frame would involve, and delivered to the day they said they would. The composite decking looks excellent.

Michael B.

Islington, N1

We went for anthracite composite decking on our raised deck and it is genuinely one of the best things we have done to the house. The team were tidy, friendly and clearly knew what they were doing. We have already recommended them to three neighbours.

FAQ

Composite Decking — Frequently Asked Questions

How much does composite decking cost in London?

Installed composite decking in London typically costs between £100 and £300+ per m², depending on the boards you choose and the complexity of the job. A 20–30m² deck in a straightforward London garden usually comes to between £3,000 and £7,000 fully installed. We provide detailed, itemised quotes so you know exactly what you are paying for — no estimates, no surprises.

How long does composite decking last?

Good quality composite decking boards are designed to last 25–30 years with minimal maintenance. Most leading manufacturers back their products with a 25-year guarantee. The sub-frame beneath the boards also matters — a properly built timber or steel frame will last the life of the deck.

Is composite decking slippery when wet?

Non-slip composite decking is specifically designed with textured or grooved surfaces that provide good grip even when wet. This makes it a safer choice than smooth hardwood or treated timber in the British climate. We will advise on the most suitable surface finish for your situation and usage.

Composite decking vs timber — which is better?

There is no single right answer — it depends on your priorities. Composite wins on maintenance, longevity and all-weather performance. Timber wins on feel, natural character and lower upfront cost. We install both and will give you an honest comparison for your specific garden — we have no interest in steering you towards whichever is more profitable for us.

Can composite decking be laid on concrete?

Yes. Composite decking can be fitted over concrete using a suitable sub-frame or proprietary fixings that allow for proper ventilation beneath the boards. This is a common requirement in London gardens, many of which have concrete bases from previous hard landscaping, and we handle it regularly.

Do you supply the materials or do I?

We supply everything — boards, sub-frame, fixings and all supporting materials. This ensures we can guarantee the specification and confirm that everything is installed correctly. If you have already purchased boards or have a strong preference for a specific product, we are happy to discuss a fitting-only arrangement.

How long does composite decking installation take?

A standard 20–30m² garden deck typically takes two to four days to install, depending on sub-frame complexity, site access and any additional features such as stairs or balustrades. We give you a realistic timeline before we start and keep you informed throughout — we are aware that having a team in your garden indefinitely is not ideal.

Does composite decking need maintenance?

Very little. An occasional brush down and a wash with warm soapy water is usually all that is needed to keep composite boards in good condition. We provide full care guidance when we sign off the job, including any product-specific recommendations from the manufacturer.

What composite decking brands do you install?

We work with all the major composite decking manufacturers, including Millboard, NeoTimber, Cladco and Trex. We can source and install any brand you prefer, or recommend what we think best suits your project, garden and budget. We are not tied to any single manufacturer.

Do you offer a guarantee on your composite decking installation?

Yes. Our workmanship carries a guarantee, and the composite boards we supply come with the manufacturer's own product warranty — 25 years for premium boards such as Millboard. We walk you through what is covered at sign-off so there are no ambiguities.

Barbie Kristal

Good, very professional company with reliable and excellent tradespeople. Always punctual when promised. Also available to speak to during any works. So important especially if there are problems. This is a company that takes FULL responsibility for its workers. So if there's a problem, no hesitation in sorting and remedying it. Joey a manager, was especially kind, caring and helpful towards me. He too, is an outstanding carpenter. I have no hesitation in highly recommending this company.

Lindsey Chadwick

Wouldn't hesitate to recommend MJ Kloss Carpentry and will certainly be using them again. They have now completed two pieces of work for us and in both cases we've been delighted with the results. Carlos, their head carpenter, is a true artisan who takes the utmost pride in his beautiful work (as well as being a lovely person to have working in your home). Maarten, the project manager, is equally easy to work with. He skillfully helped guide us through the design process offering really creative and effective solutions throughout. Any issues (and let's face it, things will always crop up on any project, no matter who you work with) were thankfully minor and resolved quickly without complaint.

MJ Paradiso

Very happy with the process to help me design what I was looking for (even before I knew what I was asking for) and the attention to detail with the installation was excellent.

Garion Gilchrist

Great experience. Delivered what we asked for and more, in a tidy and timely manor. Thanks!
