Homeowners searching for a totally hassle-free backyard upgrade should look into London Decking. With over 20 years of experience, they know how to provide a completely hands-off installation experience.
Their in-house design-and-build team handles the whole process, from architectural drawings to council planning permissions. They even take care of all the messy site prep and waste disposal.
You can pick between traditional timber options or modern composites to suit your maintenance needs. If you need extra flair, they also custom-build matching wooden structures like pergolas to tie the space together.
Unfortunately, their office is closed on weekends, which is bad news for clients needing a quick build process.
Garden transformed despite the weather!
Robert and the team did a great job of rebuilding our decking.
They turned up when they said they would, completed the work in a very reasonable time frame despite tricky weather. They use high quality materials and the decking is well-constructed. There was a good bit of problem solving too – designing the steps down from the decking and making it work in our sloping garden.
Our garden has really been transformed. We are very pleased.

Super efficient and fabulous results
Robert and his team did a great job – he was very fast with communication, visited us in person to prepare a quote and gave us lots of good advice about what kind of decking we should go for. Once we agreed everything we mentioned we needed the project doing quickly as we had family due to come and stay and they got everything done so fast, honestly I couldn’t believe how efficient the team were. Our garden looks fab, thank you Robert and team for such a great job

2. Oilcanfinish Outdoor Living

Address: 60 High St, Wimbledon Village
Contact: 7919 344450
Hours: Monday-Thursday, 9:00 AM – 7:00 PM | Friday, 9:00 AM – 4:00 PM | Saturday, 9:00 AM – 1:00 PM
One of our picks, Oilcanfinish, is a highly recognised company. They won the national Jacksons Fencing Approved Installer of the Year 2024 and hold the highest Trex composite decking installer status in the UK.
Plus, they’re fully certified Millboard Approved installers. You get premium composite decking that simply won’t rot or crack.
If you prefer real wood, they build with durable tropical hardwoods like Yellow Balau that last decades. They even offer heavy-duty aluminium frames to match their top-notch boards.
But you can’t buy your own materials and hire them for the labour. They require sourcing everything to ensure quality and stop scheduling delays.
Expert work and weekend dedication
We are absolutely delighted with our beautiful new decking. Jason and his team offered a seamless service, ensuring the whole substructure was expertly laid and angled to maximise water drainage and the surface area.
We are also grateful to Jason whose communications, professionalism and understanding of the properties of hard wood and composite decking were outstanding and who was keen to ensure the client had a deck that would last. Thank you also to Luke and Charlie who came in on a weekend when the terrible weather had slowed the project.

Fast, tidy, and super professional
Jason and his team did a fantastic job on the decking at my house. They were super professional, easy to work with, and the deck looks amazing. The team was friendly, worked quickly, and left everything tidy when they were done. I’m really happy with the results and would definitely recommend Jason to anyone needing decking done.

3. The London Decking Company
Website: http://www.londondeckingcompany.co.uk/
Address: Birchen Grove Garden Centre, Birchen Grove, Kingsbury
Contact: 20 8200 0882
Hours: Monday-Friday, 8:00 AM – 4:00 PM
The London Decking Company operates out of five different depots across the area, which gives them the unique ability to supply products and provide full-service installation.
These guys even offer full-yard remodels, making them ideal for small and bigger projects. Basically, they handle the design, material supply, and build process.
We like that they stock a vast product range, which means they can easily handle garden design, paving, and fencing all at once.
They stick to using water and rot-proof composite boards. You can also get premium, brand-name materials like Trex Transcend directly from their shop.
But their office and installation teams operate on a strict Monday-to-Friday schedule. Sadly, this limits their availability for consultations.
Knowledgeable, patient, and highly skilled
Really pleased with every aspect of service from this company – professional and knowledgeable from start to finish. Chris spent a long time making sure we were happy with every aspect of project and patiently gave us several options. Luis was in charge of building the decking and he was thorough, reliable, tidy, respectful, friendly and highly skilled. Definitely recommend this company for a high quality and beautiful decking.

Creative, friendly, and perfectly built
So glad I didn’t see the reviews for this company as we’ve had a really brilliant, professional experience with them from start to finish. Our garden looks so beautiful, the decking is solid and the clover lawn looks incredible. And the guys who did all the work were genuinely a pleasure to have around – friendly, professional, creative (worked with the project as it emerged as I kept changing my mind about the shape of the decking edges etc). Highly recommend. ⭐️⭐️⭐️⭐️⭐️

4. London Roof Gardens
Website: https://londonroofgardens.co.uk/
Address: Pavilion, 96 Kensington High St
Contact: 020 7158 0157
Hours: Monday-Friday, 9:00 AM – 5:00 PM
We like how London Roof Gardens specialises in converting tricky flat roofs and urban balconies into fully functional living spaces. This gives you a chance to get creative with your space.
Their process is thorough, too. They assess your roof’s structural weight capacity and drainage needs before starting any work.
They use an innovative hidden fixing system for a totally seamless finish. If you want real nature up high, they can even map out custom planting schemes with grass and trees.
However, this roof deck specialisation means they can’t accommodate ground-level projects. And since they exclusively use Millboard composite products, your choices are limited.
Hassle-free roof repair & value boost
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 .

Stress-free from start to finish
Lauren promptly sent a clear and detailed quote and swiftly organized the different jobs required. The team kept me informed at every step and sent photo updates regularly. 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.

5. Composite Decking London
Website: https://compositedeckinglondon.co.uk/
Areas Served: London and the surrounding areas
Contact: 07810 861 707 / 020 8058 2675
Hours: Contact for availability
Composite Decking London stands out for providing specialised A1 fire-rated decking installations. They use non-combustible aluminium and mineral-based boards to meet top European safety standards.
You can still opt for premium Millboard decking made from a tough resin-mineral blend. This comes in a variety of colours and finishes for better customisation.
On top of that, their installation process covers all the necessary structural preparation for a lasting foundation. They even offer dedicated balcony services that handle secure fixings and waterproofing preparation.
However, their strict focus on composite decking means fewer natural timber options, which is a drawback should you prefer real wood.
Smooth process and top-quality build
Arek was very professional from the time I initially contacted him for a quote. After that, everything went as smoothly as possible.
Arek is very responsive to all my questions and would reply back very quickly. His work and his team cannot be better. Every day, before he left the site, he makes sure things are tidy.
At the end of the job, he made sure all the garden furniture were returned to their original places.
My composite decking looks really good and I am very happy with its build quality.

Hardworking, meticulous, and reliable
I was very lucky to find Arek on my first attempt finding someone who did composite decking. The balcony in the apartment we had moved to was in a bad state. Arek came when he said he would to give a quote and turned up on the day to do the work as agreed while keeping me updated about his arrival time. He and his two colleagues worked hard without a break for over 6 hours and did a fantastic job. They were very meticulous and made sure they left the place clean and tidy. Highly recommended!
