Zen came round to see job and returned competitive quote quickly. He was able to start a few days later, turned up on time and completed the works with the designated 2 day time frame, working essentially 2 full days (not my experience of builders in UK who are only onsite for 5 hours a day). He cleaned up the site and did a good job. Would use him again.

I found Marcus to be polite, hardworking, and kept my property tidy at all times. I would happily recommend him to anyone looking for reliable building services and would use him again in the future.

Nico and his Upgrade Interiors team did a fabulous job converting part of our garage into a home gym. Nico was great; he would take the time to update us every time we saw him, great communication over phone, text & email, and would always check in with us on any additional expenses (which can happen with these jobs). Also gave us tips and details on how to tackle the other part of the garage. 100% recommend and will look to utilise his services again in the future - thanks again, Nico!

Conversions - General- 1 Oct 2018
Chris is a pleasure to deal with - always polite and helpful. He initially gave me the most detailed quote by far out of everyone I approached, and everything felt very professional - schedule of work and payment, contract, etc. The work on our house was completed quickly and to budget - there were no hidden costs and it felt like Chris was always honest and upfront, and willing to discuss matters. For the duration of the work, he was easy to get hold of and in constant contact, always willing to meet up on site and talk things through. His decorator is fantastic and my house looks great. Chris even added in the odd extra e.g. putting in a cupboard under our stairs. For all these reasons, I would recommend Chris. It did however take a long time for the snag list to be completed - I was very aware when I was no longer no. 1 priority, and I had to do a lot of chasing, which was a shame. But overall it's been a positive experience - I was very apprehensive about having so much work done to my house, and I have no regrets about choosing Chris.

Dariush and his team exceeded our expectations with their exceptional service and dedication. Even before the project began, Dariush made multiple visits to consult with us on various options, even making holes in the ceiling for visual inspections at our request. When I offered to pay for this "consultancy," he kindly declined. Throughout the few months on the job, Dariush and his team remained committed, working long hours, including Saturdays, compared to other builders to ensure timely delivery. Dariush consistently sought ways to achieve a flawless finish without shortcuts. What impressed me most was his openness to listen to our ideas and suggestions, taking the time to explain his perspective patiently—something rare among builders. We are very satisfied with the results and highly recommend Dariush and his team for their professionalism and excellence.

Leo and his team converted my garage into two spacious rooms. One is a shower room, the other a utility room. All the work involved from the actual building to the furnishing and finishing has been done to a very high standard. The job finished with installing a new kitchen. Everything has been done in a courteous and thoughtful way. I would certainly recommend this company for anyone looking for a competent, experienced team to build a garage conversion.

We did not go ahead with this job as we did not purchase the property, however, Craig and his team phoned me and explained to me over the phone what is needed and provided me an estimate over the phone which is what I was looking for. This helped me and put in to context what I was dealing with. Thanks very much.

I cannot recommend Andrew's work highly enough. I have already asked him to quote for further work. Andrew and his co workers were friendly, punctual reliable and the work of excellent quality. Andrew also went above and beyond what could be expected even staying late on a Friday night to tackle an unexpected historical plumbing problem. They made great efforts to keep the mess to a minimum, fantastic job well done.
