After lot of thinking we selected Proficiency for our new build. Nearly in a week it was clear that we have selected the good builders. House was built in time with professionalism. Jimmy, Besi and Luli are the best team together. They understand clients very well. We thank them to deliver the fantastic job. Highly recommended with full confidence.

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

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

We undertook a big project – demolition of an old extension, double floor extension, garage conversion, internal remodelling and full refurbishment including re-plaster, re-wire and re-plumb. We were complete novices so spoke to 6+ different building firms to get quotes, and Proficiency were the most impressive from the start. Their dedicated contract manager Phil worked with us in detail which is what we wanted, always giving quick responses and never pushing us to just get started and worry about the details later, which is what we experienced with some other firms. Having Phil manage the quoting

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

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

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.

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.
