The 5 Best Deck Builders in London for Your Home
Upgrading your garden totally transforms the way you enjoy your home. A solid deck gives families a safe, durable space to host weekend barbecues and outdoor gatherings.
Retirees really appreciate having a low-maintenance, accessible spot for morning tea in the fresh air. Plus, upgrading your outdoor space drastically increases property value if you’re a landlord looking to rent or sell.
Finding the right contractor can feel simple once you know what to look for.
I’ve tracked down the best deck builders in London to help you compare your options and finally get that backyard project started.
How much does deck building cost in London?
A typical homeowner can expect to spend between £800 for a small setup and over £9,000 for a premium outdoor living area, with local labor rates driving costs slightly higher than the national average.
| Material / Size | Average Cost |
| Softwood / Pine | £50 – £80 per m² |

1. London Decking

Hours: Mon – Fri: 8am – 5pm
Finding a team that specializes in fully bespoke timber constructions makes a great difference for unique outdoor spaces. London Decking excels at tailoring every single build to match your exact vision.
I recently spoke with a homeowner in North London who praised their meticulous attention to detail from start to finish. They supply gorgeous hardwoods like Iroko alongside ecologically sourced softwoods certified by the Forest Stewardship Council.
You can easily match your home’s unique aesthetic with their extensive composite selections, too. In fact, their popular gray and black boards remain massive hits for clean, modern layouts.
Beyond just flooring, they also construct beautiful garden structures like custom pergolas to pull the whole backyard together.
The only catch is that their hyper-focus on fully bespoke projects might deter homeowners who are just looking for a quick, standard deck installation.

We love the new deck and would highly recommend this company.
Great job done on replacing our decking! We had the job booked in and finished within a couple of weeks of contacting the company. We got good advice about what materials to use. Arthur worked solidly for 5 days and was considerate and very efficient. We love the new deck and would highly recommend this company.

They were polite and professional to deal with and I would not hesitate to recommend them.
I was impressed by the level of craftsmanship demonstrated by London Decking when building our new patio decking in the back garden. The job was completed quickly, efficiently and with bespoke touches given the quirks of our Victorian property. They were polite and professional to deal with and I would not hesitate to recommend them.

2. The London Decking Company

Website: https://www.londondeckingcompany.co.uk/
Address: Birchen Grove Garden Centre
Contact: 020 8200 0882
Hours: 8am to 4pm Monday – Friday
Getting that classic natural wood look without all the hassle of rot and constant maintenance is exactly what The London Decking Company provides. They proudly supply and install top-tier Millboard composite ranges.
These hand-colored boards offer incredible durability for busy family homes that see a lot of foot traffic.
I actually stood on one of their Millboard installations at a neighbor’s house last month, and it felt remarkably like real oak minus any annoying splinters.
If you still prefer the real deal, they also specialize in gorgeous tropical hardwoods. They source premium materials like Ipe and Balau from multiple continents to give you an authentic finish.
The only thing to keep in mind is that they manage a wide variety of broader garden services. This can occasionally lead to minor booking conflicts during peak landscaping seasons.
Customer Reviews

From start to finish this was a wonderful company.
From start to finish this was a wonderful company. After being quoted silly LONDON prices for my SW5 property I was happy to finally have a reasonable quotation. All the way through all the staff were open, friendly and professional. They did a great job and would be happy to recommend them. Many thanks to you all for making it a pleasure when working with tradesmen can be hard work.

3. Oilcanfinish Outdoor Living

Website: https://oilcanfinish.com/
Address: 60 High Street
Contact: 07919 344450
Hours: Book to schedule service
Turning an unusable rooftop into an entertaining space takes great technical skill, and Oilcanfinish Outdoor Living handles these complex projects as a TrexPro Platinum installer.
I like that they specialise in detailed outdoor builds rather than treating decking as a simple installation.
They design and install premium composite layouts across the city, while also handling the finishing details.
A colleague who hired them also raved about their structured approach. The team plans staircases and installs sleek glass balustrades, giving the finished space a more complete look while adding safety around raised areas.
You can also visit their supplier showrooms in South West London to see display setups without booking an appointment, which is useful for getting a better feel for the materials.
The main limitation is that they focus almost exclusively on composite decking, so they may not suit anyone specifically looking for a traditional timber build.
Customer Reviews
We are absolutely delighted with our beautiful new decking.
We are absolutely delighted with our beautiful new decking.

4. Prime Builders London Ltd

Website: https://www.primebuilderslondon.co.uk/
Address: 16 Myddleton Avenue
Contact: 07889 510207; [email protected]
Hours: Monday–Sunday: 07:00–7:00 PM
Homeowners who want to completely overhaul their outdoor space will love this contractor’s broad, all-in-one approach. Prime Builders London Ltd seamlessly integrates stunning deck construction right into wider landscaping projects.
They operate as a full-service building contractor with over twenty-five years of hands-on industry experience. Having one team manage both your paving and your decking makes the entire backyard renovation process so much smoother.
Because they handle full-scale builds, they can easily coordinate multiple trades at once. They can even tackle complex kitchen renovation alongside your outdoor upgrades if you’re taking on a bigger house project.
The only real trade-off is that deck building is just one part of their massive suite of services. This can occasionally lead to scheduling delays if they are tied up on a larger structural job.
Customer Reviews
Robert and his team are worth their weight in gold!

Robert and his team are worth their weight in gold!

5. London Roof Gardens

Hours: Book a consultation / get a quote
Building a safe outdoor space requires some seriously specific engineering expertise. London Roof Gardens steps right in to fill that exact niche as a specialist contractor focusing entirely on bespoke roof terraces.
Because of that high-level technical focus, a former client I spoke with mentioned how seamless their entire terrace transformation felt from start to finish.
They expertly combine custom deck construction with vital structural load-bearing assessments and heavy-duty waterproofing systems to keep your property protected.
Their crews also use advanced pedestal systems that build perfectly level surfaces over sloped roofs. This method not only safeguards the underlying waterproof membrane but also ensures proper rainwater drainage during heavy storms.
To top it all off, they exclusively install high-end Millboard flooring to achieve a premium, wood-free finish that stands up effortlessly to the elements.
The only drawback to keep in mind is that their operation revolves entirely around elevated terrace conversions. This means they won’t take on standard ground-level garden decking projects.
Customer Reviews
Darren and his professional friendly team did a wonderful hassle free Job
Darren and his professional friendly team did a wonderful hassle free Job replacing my entire roof which was old and leaking and then decking out with Milboard to make a roof terrace. They took such care and attention to the joints, sky lights, railings and details. Nothing was too much trouble and they produced a first rate Job, which I know will have increased the value of my property well above what I spent doing it .

I will be calling them again for future jobs without a doubt.
Each day the house was left clean and tidy. Even though they had to redo all the balcony (insulation, decking, balustrade…) it was a stress-free experience and the final result definitely exceeds my expectations. I will be calling them again for future jobs without a doubt.
