We hired Proficiency Design and Build in January this year to build our extension. They were absolutely amazing. January was not a great month in the UK weather wise and also with Covid but these guys were always upbeat, professional, and they worked tirelessly to get the job done. Toby the project manager was always there to answer any questions and give advice and he came around to check the project every few days which we have never had from any other building company. Besi was the site manager and he worked incredible hard throughout the whole project talking us through it all step by step.

We have lived in London 17 years and over that period of time we have hired quite a few builders, plumbers, painters etc. Proficiency Design and Build exceeded our expectations! I would highly recommend this company.

Delivered on time and we got the specification we asked for. Professional and responsive to our needs. Builders on site were always professional, neat on the job and enjoyed what they did.

Proficiency has just completed the renovation of our flat. We are extremely pleased with their work. It was a multi-trade project, and all elements were carried out with the utmost professionalism. Problems were anticipated and resolved in a timely fashion. As a result we have a high quality finish, completed in time, and within the anticipated budget. There are excellent personnel employed to smooth the process. Thoroughly recommended.

Proficiency was recommended to me by friends who were incredibly happy with their work. As a result, I worked with Proficiency on the refurbishment of my flat, including design for an extension, strip out, reinstating the old flooring, complete rewiring, moving & installing new radiators, remodeling the bathroom which included new plumbing, tiling, installing underfloor heating and turning a cupboard into a walk-in shower, as well as decoration of several rooms.

This was the first time for me to take on such a project, and I found Proficiency incredibly helpful, reassuring and transparent on both, timelines and costs. Shout out to the best team Besi, Toby and Phil who were a dream to work with, providing regular updates, patient hand holding and generally went the extra mile wherever possible to ensure work was delivered at its best standard and to my ever changing mind. Furthermore, all their teams were trustworthy and incredibly friendly, which I found very important as I already lived in the flat throughout part of the work. I can highly recommend Proficiency and once the extension plans are approved I will not hesitate to continue working with Proficiency.

Besi, Toby and and the team were so helpful. I wish I had started my job with their architect who helped me sort out the mess that my original architect had left me in. And so it continued, they were always helpful, offering up creative solutions, going above and beyond and provided such a high quality of work. And fast too! Just amazing. I will definitely use them again for anything I need doing and can't recommend them enough.

We worked with Proficiency for a full conversion of our apartment, including glass extension, garden remodelling, reorienting of floorplan to create two bedrooms, full refurbishment and redecoration. Proficiency also supported with elements of design and re-drawing given we were unhappy with the services of our architect. In particular, I would call out their transparency on cost throughout, providing regular updates and itemisations to ensure there were no surprises at the end of the job.

I would not hesitate to recommend this company - at all times they were responsive, professional and went out of their way on many occasions to ensure the job was completed to our satisfaction. The team (in particular Toby, Besi & Phil) who led our work were brilliant, and we have recommended to several close friends (2 of whom are using Proficiency for their own work right now).

After experiencing bad builders (both work wise and attitude wise), Proficiency was a relief to find and work with. They were recommended by our friends who's flat they had renovated. The proof was in the pudding, our friends were extremely happy and we could see the difference in finishing. The team from proficiency is extremely professional, honest and upfront right from the start. They can seem pricy but the quality of work, service, finishing on time and their overall attitude makes the experience extremely stress free and absolutely worth it.

I had renovated my bath a year ago (which is now going to be redone by Proficiency) and it was extremely stressful for a small bathroom and had lot of hidden cost. They were in constant touch throughout the project and also after the project. Their work comes with warranty and they stick along to fix anything required. For us, apart from the overall experience, the things that stand out is project management, time management and the service provided (being provided) by the entire team (including the electrician). I highly recommend this team and will very happily use them for all my future projects

I am so happy I came across Proficiency after dreadful few months dealing with unprofessional construction company and architect! Besi and Toby were working on my project of completely refurbishing my apartment, everything has been done with good quality and good value. Even after my project has finished whenever I had questions to ask Toby and Besi always are very responsive, which I appreciate. I can not recommend this company enough! Definitely will get back if I have projects in future.

We decided to go with Proficiency based on research I did for good builders on the internet. Proficiency was quick to respond and they setup a meeting to discuss the project. Being hesitant at first, we had several discussions and decided to see their work. Having visited their sites and talking to the owner, we decided to go ahead. The estimate was 5 months, and pleased to say they delivered bang on time.

Their attention to detail is amazing and throughout the project the site was clean and tidy. The entire team is professional, on time and polite - and always had a smile on their face (perhaps the painter not so much, but he did a brilliant job :)). We never had any complaints from any residents. Jimmy (owner) has immense experience and helped and guided us throughout giving us ideas for the final touches. We have an amazing home, and couldn't have achieved it without their help.

I am pleased with and grateful for their work on my flat refurbishment. From site survey, design and build, to final finishing touch, they helped me throughout the project. They were really professional and did not compromise on the quality of their job. Not only they were willing to accommodate my many special requests, sometimes change of plan at the last minute, but they were not shy away from making practical suggestions, which all proved to be invaluable. I guess for most home owners building projects are painful process, but oddly for me this has been an enjoyable journey thanks to their great team.

Fantastic builders who really care about the quality of finish. I have used them 3 times this year and each time the project came in on time and on budget

Great construction company. Project manager did a fantastic job at my home extension. Architect also did a great job. I was able to came to office and see my extension in live demonstration. Architect advised me what was possible to build and what not. At the same time while I was visiting their office I also had a chance to get a consultation about interior design. In overall pretty good building company.
