Architecture- 13 Apr 2015
We are extremely happy we chose to use Phil for our loft and extension design. Phil is professional, extremely accommodating and a pleasure to work with. He was always contactable, punctual and happy to spend a lot of time with us to discuss designs and the planning process. His design ideas were smart and he presented us with a number of workable options. We wouldn’t hesitate recommend Phil and would certainly use again for any architectural works.

We have been working with Derek Borkiewicz (Sebek Construction) on a renovation of a garden flat in Little Venice since last autumn. We needed to completely restore the whole flat, including the garden. This was our second renovation project and by this time we knew what we wanted to do, which mistakes to avoid and what to pretend from a qualified builder. We will never stop saying how lucky we have been to find Derek and his team! Derek is not only a professional builder who is very careful to the smallest of the details. He is not only a very good project manager who is constantly checking the work of his men. Derek is a friend who takes on board a project like it is his own project. He suggested the most convenient and best solutions for any problem we came across during the works. There wasn’t a time when he didn’t know what to do to solve a difficult situation (and there are lots of small and big issues coming up in a renovation work) no matter how complicate they were and how long it took to solve them. His availability and his courtesy are incredible above all in a fast running city like London. This is priceless to us. His hard work can be seen in the wonderful result we reached with this garden flat. If we ever decide to work on another project we won’t think twice about working with Derek once again. In fact, now that we found the perfect man to work with, we are looking forward to finding another renovation project to work on! Monica

Extensions- 26 Sep 2022
Excellent work with the garden office/gym. Finished really nicely and exactly what we were looking for. Took quite a while but well worth the wait. We requested a labour quote and worked with Alf on a receipts basis for material and other costs. This worked out perfectly for us both. Alf's initial estimate of the materials cost was virtually spot on, which is very impressive given the inflation rate for building materials. Thanks again for all your hard work!

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!

Bathroom Fitting- 10 Nov 2013
Andy and his team did a good job replacing our bathroom and cloakroom. The job overran due to a couple of logistical problems with different tradesmen, but Andy did his best to minimise the disruption. Good communication and accurate quote, which was stuck to. Overall, we're happy with the outcome.
