We cannot rate James and his team enough, from start to finish they were fantastic. James is a very professional project manager with high standards. He maintained excellent communication with us throughout our project and was always available when quick decisions needed to be made or problems arose. He is a quick problem solver and will go out of his way to avoid any inconveniences for you as a customer. His team consistently exceeded our expectations, not only in the quality of their work but also in completing the project within an impressive timeframe. All of his team were professional from their branded uniform to the respect they showed towards our home the entire time. We are more than delighted with the finished product, and absolutely love our new space, we would highly recommend James and his team to anyone looking to do similar work on their home.

James undertook a substantial whole house refurb for us (inside and out). This included a wraparound extension, new roof and all the associated key trades. Every single team member was excellent.
James has absolutely been standout from start to finish. I truly can't fault his workmanship, attention to detail or speed at getting the job done!
James remained patient with us throughout despite my high level of indecisiveness.
Original estimate came in on budget with no shock extras / hidden surprises. James remained transparent throughout the process.
The site was kept nice and tidy throughout.
There was an issue with the original downstairs layout due to an architect error, but James quickly took time to sit down with us and prepare a complete internal redesign, the output of which worked out significantly better than the original configuration.
I can't recommend James enough!!!!!

We couldn’t be happier with our new bathroom.
James managed the process really well - correctly anticipating some issues that needed resolving and, together with his trusted and trustworthy team, focused on finding solutions. He also went the extra mile to resolve a couple of glitches even when they weren’t of his or his team’s making, rather than disappearing as soon as he’d been paid.
We would 100% recommend Cogent, James and his highly skilled team.

We recently had a small extension added to our home and were very impressed with the builder's service throughout the project. As this was our first time embarking on a major house improvement project we were nervous to start given we had a baby due during the construction but James made us feel very comfortable the whole way. Communication was clear and consistent from start to finish, and any questions or concerns were addressed promptly. Everyone, including sub-contractors, were professional, reliable and managed to get the job done quickly.
One aspect we really appreciated was the flexibility they offered with payments, allowing us to pay in arrears, which helped with our budgeting. The quality of the work was excellent, and the whole process was handled smoothly and efficiently.
We absolutely love the space they've created for us - it's made a big difference in our day to day living. We've already recommended James and team to several people!

From the outset of our planning discussions to the final touches of our extensive renovation, James and his team demonstrated a comprehensive understanding of our needs. Their expertise and experience were invaluable, with James consistently available to address any concerns, no matter how minor. The quality of the finished work has garnered numerous compliments from friends and family alike. We wholeheartedly recommend Cogent for any project, regardless of size.

Cogent worked on a challenging commercial space needing a bespoke approach and high end finish. A change of layout, plumbing, electrical work and the requirement to repurpose existing cabinetry was met with a can do attitude, offering elegant solutions to any issues encountered along the way.
The continuity of the team ensured a smooth, timely completion within budget. A special mention to James who liaised brilliantly with the architect and myself, as well as with third party suppliers. His support, patience and communication made the process smooth and efficient and he was a pleasure to work with.
The team at Cogent are professional, responsive and committed. I have worked on several projects like this and all had a long snagging list at the end, this didn’t have a single one; a testimony to the quality of work delivered.
We will use Cogent for future projects and I highly recommend them to anyone looking for reliable, skilled professionals with a true sense of craftsmanship.

Cogent did a fantastic job regarding our double story extension in Chislehurst. They came highly recommended following undertaking extensive works on other properties on our road, and we would highly recommend them following our own experience. Their communication was always clear and extremely timely, with any challenges proactively identified and resolved. The quality of the work was to a very high standard and done in a quicker timescale than we expected, minimising disruption to our lives. James and his team went above and beyond to provide pragmatic and smart solutions and ideas, which overall improved the outcomes of the project. The build was project managed from start to completion, with James always willing to answer our questions, supported by sub-contractors who were also very diligent, and professional in their approach.
Overall, we are extremely pleased with the outcome and that we chose Cogent.
