Bathroom Fitting- 14 Nov 2019
We had our bathroom completely refurbished and Graham the owner was lovely. He came to give us the quote, visited whilst work was being undertaken to make sure everything was okay and came to make sure everything was finished to how we wanted it. The work carried out was of a high standard and whilst the bathroom work was being completed we also ended up getting our kitchen worktops done by Graham’s team. Chris was the one who carried out our work, he was very friendly and checked we were happy with the work he’d done before he left everyday. I would use Graham again for other work needed around the house.

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!

Extensions- 21 Sep 2019
Ray has done an outstanding job with the new extension. He has shown great attention to detail and accommodated every request. The result is one that we are extremely happy with. He installed a new bathroom downstairs complete with all necessary pipework and a new utility closet with exits for the washing and dryer. Clearly Ray has a very broad set of skills, from electricity to building to carpentry, plumbing and roofing. He really was the one stop shop to make this extension a reality and has a network of people he can call onto if required. He is certainly someone that takes pride in his work and wants a job well done as evidenced by his work. I recommend Ray without a doubt and I'm sure our paths will cross again. Thank you Ray!

Bathroom Fitting- 26 Aug 2026
Reza quoted two weeks to renovate my bathroom but finished in just a week and a half. He brought in a team of three who worked efficiently and completed the job to a high standard. They were polite and courteous and took great care to cover all staircases and carpets, ensuring no damage was done to the house. When extra help was needed with the heating, a specialist engineer arrived promptly and completed the job smoothly. I highly recommend his services.

Extensions- 5 Sep 2019
One of the best builders I have ever worked with. PMB take great pride in the work they do and finish to a exceptional level (even better than a lot of premium and expensive builders in the industry). Colin's knowledge about all aspects of building work is unmatched and that shows in the end product that he and his team delivered for me. PMB did a full refurbishment & substantial extension (everything knocked down except 3 external walls) - ground floor ext, first floor ext, loft extension, full re-wire, plumbing, gas, UFH, walls, plastering, fitting, decorating etc. His prices are reasonable and he advised when unexpected costs come up so I could make a decision on what to do. I will definitely use him again.

Decking- 29 May 2020
Started on time and completed the decking extension & renovation to a high standard. Ensured that small details like cuts around poles etc, were finished properly and not left with gaps. Next time I would confirm that clearing rubbish is part of the quote, but highly recommend Przemek for quality finish.

We recently had Landi around to quote on a number of jobs we needed doing around our house. We booked him to fix our roof, which was leaking water - he and his team did an absolutely fantastic job. They were responsive, thorough and did a great job. We won't hesitate to recommend him to anyone and get him back for any work we need doing.
