Bathroom Fitting- 15 Jun 2022
Mateusz, better known as Matthew, has just completed a job at my house consisting of replacing our bedroom ceiling, installation of downlights, repairs and redecoration, as well as the installation of a concealed shower, shower tray and cubicle, which involved some retiling and electrical repairs to mirror lights & switch. Matthew has done a great job, working conscientiously and paying attention to every detail. We are delighted with the outcome and it has been a real pleasure to have him working here. The work has been completed to a high standard and for a very reasonable price. I have already recommended Matthew to a neighbour and I would not hesitate to ask him back to do more work for us in the future.

Hard Flooring- 11 Sep 2025
I’m not happy with the job George did for me. Just a day the floor started moving. I contacted him and he cut the call on me like I’m a piece of shit. I am a sick single mum struggling. He took £2500 from me and the job is not good. I’m sad and disappointed in him.😭😭😭😭

Conversions - General- 10 Dec 2017
Gary and Bryn have done a great job on our garage conversion and we are extremely pleased with the work they carried out. They ensured all structural work was completed to an excellent standard and they put in extra hours without complaint and free of charge where aspects of the job were more complex than anticipated. Each day they took care to tidy up after themselves. I received a number of quotes for this work and GB Refurbs’ was by far the most reasonable. All costs were transparent and fixed – there were no hidden extras as there can be with some builders. Aside from the quality of their work, Gary and Bryn are lovely guys and couldn’t do enough for me. While they were here they also carried out a couple of other odd jobs free of charge and without me even having to ask! I’m so impressed at the breadth of skills they have and will definitely use them for future jobs.

I recently used PrimeUK Contractors Limited for conversion works at our studios in Camden, and I couldn’t be happier with the results. The project timeline was set at six weeks, and the team delivered right on schedule. Pavlo and his team had a clear understanding of the scope and what needed to be achieved, going above and beyond to make the project a success. The quality and attention to detail in their work were outstanding, and my entire team was thrilled with the final result. Their pricing was competitive and fair, which was another bonus. When we have more work in the pipeline, Pavlo and PrimeUK will definitely be my first call. Highly recommend!

Conversions - General- 16 Sep 2019
Finding a builder you can trust can be so stressful, we know so many people who have nightmare stories. I am so happy to say we could not have chosen a better team for our garage conversion. Adrian and his team treated our home and this project as if it were their own. They showed up early every morning ready to work, no matter the weather and always cleaned up the building site before they left. Our next door neighbours had an extension done earlier this year and the team they chose left their property and home a mess every day. We expected this to be the case when we had our garage converted but Adrian and his team always left our property clean and tidy before leaving for the day. We loved how Adrian was attentive to what we wanted and made suggestions as well. The end result has exceeded our expectations and we know we will get incredible use of our studio for years to come. Any future projects we have we absolutely will be using Allushi Construction.
