Gas Work- 26 Oct 2025
I was able to get my own boiler and just pay for the extra material and installation. Not all traders accept this. The price was very competitive. I was sceptical at the start but was reassuring on how quickly the job was completed. There was an issue with the thermostat but was sorted out the following week. The gas certificate, building compliance and boiler registration was completed promptly. Would definitely recommend, please allow Shami to quote before making a decision, you won't be disappointed.

Plumbing- 24 Sep 2018
Had confirmed I would take a day off for the job. Received a text on the day at the time he was meant to come saying van had broken down and could not come. Then offered to send a friend to do the job. Waste of a day and spent morning running around buying the equipment. If the van did really break down then that’s a fair excuse. Negative experience from my end.

Restoration & Refurbishment- 27 Mar 2022
Ricky Reid I was looking for a company who could help me with a light refurbishment (kitchen, bathroom and full decoration) of a one bedroom flat in south west London to be ready for rental within 15 days. I posted my ad request on mybuilder.com and a few companies contacted me. Ricky Reid, was the third one I met and eventually the one I chose. Why? R. was straight forward, no gimmicks and did his best to understand what my needs were from day one. Especially when my vision at the start wasn’t that clear. Him and his team delivered within the time frame agreed as well as within the quote given plus a few extras that hadn’t been considered at the start of the project. He was always available for questions or clarifications needed over the phone at any time! A rare quality in itself in the building world. If there was anything that could be improved, this would be clarifying certain jobs that were on the quote (and I mean specifically what they exactly covered) from the start to avoid stingy or unexpected surprises cost wise. However this isn’t Ricky’s fault and I take my full responsibility as I should have done my homework before hand. Overall satisfied with the result and I would certainly contact Ricky and his team for my next future projects and so should you reading this review. Thank you Ricky and all the best in your company venture.

Loft Conversion- 16 Mar 2014
Alex undertook several roof repairs as result of storm damage. This also required making good of interior damage as well. As a result of his good work doing this job I gave him job of redecorating an entire room, this including installing coving. Overall Alex and his team did an excellent job, any issues I had were dealt with and they went above other builders in terms of the care they took to my house when doing the work. I am already looking to give Alex further larger jobs in the next few months and will happily recommend to friends and family. Ravi Mill Hill, NW7

Extensions- 11 Jan 2018
This was our first project, and we were exceptionally fortunate to find Bujar. We're actually getting tired of hearing our family and friends tell us how lucky we are and how amazing he sounds. One of the most honest, trustworthy, and genuine people I've ever met. If I had a problem, he'd be one of the first people I'd call! In fact I did last week and he came to the rescue :) His team were all friendly, polite, conscientious and very tidy. They worked around us as much as they could, always making sure we had access to what we needed which sometimes meant it took them longer to work. Bujar is a perfectionist and is so proud of what he does, he made sure everything was done to a high standard - the estate agent who came round after we were done was impressed! His prices are very fair (better value than other quotes we got and much less time). We couldn't believe it was done in the 3 months he said it would take, and we managed to fit in a few extra bits and pieces after that. He was so helpful throughout, took all project management on and didn't bother us unless an important decision needed to be made. He drove us around all over the place to sort kitchens, bathrooms, etc. and gave us really helpful advice throughout the process. Highly recommend him and his team. I can't imagine ever wanting to look for another builder unless I had to - something that is quite common amongst Bujar's clients. We are extremely pleased with everything about our new house.

Benny and his team completed our loft conversion in 2022 and we've been very happy with the work carried out. From the beginning of the quote process through to completion, Benny and his team were extremely professional, hardworking and reliable. The work was finished on time and as quoted.
