Extensions- 19 Jun 2016
Neno is a very warm-hearted and genuine person. He gives his 100% to the job. He is also very prompt when it comes to communication and is always available by phone/text/email. He has a vast experience and good technical know-how and produced excellent plans and drawings. His quotes were very reasonable and offer excellent value for your hard earned money. Having been his client, I am genuinely inclined to believe he is a person who would never "rip off" his clients. He is a man of his word and does what he says. However, Neno's honesty and confidence can be a bit blunt at times. He can be quite “direct” with his opinions and this may rub off some people the wrong way, e.g. your local Council Planning officer may be an a**hole, but if you "confront" him, he will definitely not make things any easier for you- nevertheless, Neno dealt with all the Council red tape and followed up the Planning Permission Application to its conclusion. We finally got permission for extending the property much less than what we had expected initially- apparently our local Council (Hillingdon) has its own set of Draconian conservative rules that we were unaware of- but we have postponed the actual project work due to a recent change in personal circumstances. Summary: Based on my personal experience, I would DEFINITELY RECOMMEND Neno as a bona fide Tradesman on MyBuilder.com.

Extensions- 4 Jan 2026
I hired Amrit based on positive reviews, but my experience was extremely poor. The work showed all the signs of a cowboy builder. I’m sharing this to help others avoid the stress, delays, and financial risk I went through. 1: No Respect for Contract or Deadlines Contract deadline was 15th September, which he completely missed. Despite delays, he demanded money almost daily. When I referred him to the payment and work schedule he signed, his response was: “I didn’t read it, I just signed it.” 2: Dangerous and Unprofessional Working Practices Brought in unqualified workers, many of whom could not speak basic English. He ignored safety standards throughout the project and wanted to use the same unqualified workers for gas work, which is extremely dangerous. When I objected, his response was: “Don’t worry, you will get a new house if it blows up as you have insurance.” 3: Work failed multiple building control inspections. He eventually refused to cooperate with the building inspector.

From even before the job started I knew I’d made the right choice. The communication was truly 10/10, not too common nowadays. After 2 long days of hard graft in the summer sun the place looks a thousand times better, we’re dead happy and have met two great guys in the process 👍

Latest review:
Peter was the on-site foreman on our complete house renovation, which took just over a year. This included an additional ensuite pod bedroom in the roof and a side-return and extension to the kitchen. Peter was totally reliable throughout the project and thoroughly professional. Throughout this time we were living in the house with the children. He was always on time, managed the on-site team well and communicated clearly with us. His workmanship is high quality and he was also a stickler for checking the work of others and getting it updated if it wasn’t up to scratch. I have no hesitation in recommending Peter.
