Extensions- 3 Jun 2020
Mohit and his team at Shivay Developments completed extensive improvement work in my house (rear extension, internal structural work, kitchen, toilet, boiler installation, plumbing and electricals, flooring & finishing). The end result exceeded all my expectations in terms of cost, time and quality making me a very happy man. Sharing some pictures would have done proper justice but unfortunately there doesn’t seem to be a way to upload pictures with the feedback. In spite of living inside the property whilst the works were ongoing, we hardly felt any impact owing to how well Mohit had planned the whole thing and the advance notices he used to give us from time to time. All the guys too were very considerate when it came to minimizing the inconvenience all the dust and noise could cause to us and also the neighbours. I also liked the fact that nothing was rushed and a great deal was given to attention for details and the result was just splendid. I guess at the end of the day, it’s what you see that matters most. However amongst everything that hit the right notes for me during the entire process, it was the confidence that I can trust this team to do the job right stood out. It was a bunch of warm and friendly people who had direction and knew what they were doing. A special mention and a big thank you to Kash and Pala to lead the work from the ground up and Mohit for taking up and managing the job and of course for the celebratory rounds of beers :) Do keep in touch

Plumbing- 7 Aug 2018
I gave this person the plumbing work for my house extension and renovation for the existing of the house, at first this person was polite and well behaved, after he was given the first instalment, his intentions became clear. The contract, which was signed by both of us, was ignored. it was allegedly written by his 17 years old son, who left them and that the man is not responsible for the contract. Whilst the man and his brother were doing the plumbing a few things which were lying around the house had gone missing, as well as the fact that he had just spontaneously disappeared for two-three weeks at a time on multiple occasions. In each occasion he had brought up excuses such as his wife had a heart attack or he had been to Poland for a bereavement. Towards the end his attitude had changed as he became more aggressive. He had persuaded me to give the last installment and promised to be devoted to the task at hand. As soon as I entrusted him with my hard-earned lump sum from my pension he took his tools and left, resulting in me having to find other tradesmen to do the remainder of the work. In his profile he advertised that he has a diploma and many other qualifications in plumbing, I have my doubts as he could not hold a basic conversation in English. This made me suspect whether he really did receive these “qualifications”. His work had many faults within it which forced me to turn to another plumber.

Architecture- 17 Sep 2025
Overall we are happy with the work that has been done, however the whole experience has been soured by the fact that I am still chasing to have the new hot water cylinder properly commissioned almost 2 years after installation meaning I cannot have it serviced and won't be able to claim on the warranty if things go wrong. My home insurance will also not pay out on any damage that may be caused. The other issue is that the two consumer units that were installed have not been labelled so I have no idea which breaker does what, this is a safety concern. My many attempts to contact Mandeep about this have been fruitless, I'm just being ignored.

Bathroom Fitting- 25 Mar 2024
He was good when doing the job, and workmanship was very good, I cannot complain about that. I think what let down the entirety is aftercare & integrity of the builder. The fact we had given him multiple jobs in our house not just this one, and the first big issue we had within the first 2/3 months where our electrics stopped working in the bathroom for him to refuse to come unless I paid him £80? People usually give warranty with work and he claimed he doesn’t give more then a month which I find concerning especially with plumbing work, imagine a small leak getting worse over time before finding out. Luckily I had building insurance so when an electrician came out he said the builder had not tightened the pull switch which came loose, and I’d have had to pay to just tighten a switch. Now he’s blocked me on what’s app & for me that’s concerning and very unprofessional
