Proficiency Design and Build Reviews

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.

Besi , Toby 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.

Proficiency have just completed a complete renovation of our flat in London over the past 3 months. We’re very happy with the result, they did a great job - we have high standards and they delivered. The team we had on site were excellent and we built up a great working relationship with them as the job progressed. In the last few weeks, we could feel that they wanted to do a good job and were very flexible working around various delays (eg kitchen).

We wanted a complete house renovation including a side return with extension and an attic conversion. One of my big fears was turning up and finding no one present and having to chase workers, this was never the case. Jimmy and Toby were also very much across and able to work in tandem with the other suppliers/tradespeople. From kitchen fitters to window manufacturers to bathroom suppliers. It was immensely relieving having someone to manage delivery’s and 3rd party involvement. The results really do reflect Proficiency’s work ethic and dedication. The house is lovely and the works have sympathetically turned a tired 1930s semi into beautifully characterful modern family home. I am profoundly happy I listened to that instinctual feeling and went on this journey with Proficiency at my side. I cannot recommend them highly enough and if you want to know anything more specific please do get in touch (ask Toby for contact details).

Extension and renovation project on Ringwood Avenue. Thank you to @proficiencyltd for the first class execution of the building works


Jimmy and his team built us the home of our dreams - a full refurb with extension within 3 months! It was far from a straightforward project but their experience was invaluable. I have no hesitation in recommending them, great builders are a rare find.

I've had the pleasure on working with Proficency Design and Build now for a little while, and i have always been impressed by the quality of there work. All of their clients seem really happy with the work carried out, and how they have transformed their homes. They are always very good to photograph as well, and I'm looking forward to the next project. I'd highly recommend them.

Just over a year ago, I purchased my first renovation project. I had never done anything like this before and after searching the web I sourced 4-5 quotes. I decided to go for Proficiency because they were reasonable and their quote was well structured and detailed through out. The Job included a lower ground extension and house renovation. I have nothing but good things to say about proficiency. Their work was done to the highest of standards. Their tiling, carpentry & painting were exceptional and the project was completed on time and within budget. They we're negotiable about interior design changes and allowed me to be very involved in the process even to the point of helping me source particular fixtures I wanted for the house, keeping in theme with the style we had gone for. They gave me helpful advise on certain elements I had overlooked such as up-cycling the existing floorboards, additional water pumps needed and centralising the external bi-folds to make the extension symmetrical from the outside rather than inside. On request Proficiency made cabinetry around our fireplace to match our new Tom Howley Kitchen and honestly, the craftsmanship and detailing makes them look identical. Once the project was finished it's was had to believe its was same house.

They managed an end to end design & build project for us perfectly. Problems that inevitably crop up were swiftly and pragmatically dealt with. They took care to try to manage the budget and took real pride in making sure the finish I wanted was the finish I got. When you both work, having a Project Manager you can trust us so important and quite rare. Jimmy was brilliant as were his entire team. We’ve ended up with a home to love and could not have done it without them. I’d not hesitate to recommend Proficiency and especially Jimmy and would use them again in a heartbeat. Thank you.

The professionalism and quality of the workmanship was outstanding. It really felt like working with a partner on the project rather than a contractor, e.g. On a number of occasions they were able to find improvements to the design and outcome and managed the budget in a way that gave me total confidence. Thanks to Jimmy and his team for building our beautiful home.

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.

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 their great team.

We were very anxious as this was our first project of this type and our first baby was due in four months after the start date. As such, the project had to be completed in a short and fixed period. We also had a few preliminary issues (delays in Party Wall Act notices and the snow in early March) – as such, work started a couple of weeks late. Even then, Jimmy, Besi and the guys finished early and to budget. They did a very good job and the build quality is excellent.

Whilst I know Marie has already said thank you for the amazing refurbishment you have recently completed as well as the incredible generosity in sponsoring the theater. We have all been impressed with the quality of the workmanship and would like to formally thank you on behalf of the Board of Trustees.
