Reviews on Google:- “ Great service and good value. Nish and his colleague arrived exactly on time and got the work done in prehensive and professional manner. Our job turned out to be a big one and Nish went the extra mile to ensure we got our money's worth, waiting to check that the radiators would all heat up properly. He explained everything that he did and was happy to answer the questions. Everything is working perfectly fine now. Will be using again and would highly mend.” – Parth Shah – October 2014

Reviews on Google:- “I have always struggled to find reliable, knowledgeable, honest and reasonably priced tradesmen to take care of my properties. I can honestly say Nish Malwenna and pany Unic UK is all of those things and more. I have used him exclusively for the past 3 years for both small emergency jobs and large boiler refits and the quality of his work and knowledge has been exceptional. He always exceeds my expectations. For example recently he attended a job on a Saturday morning which was an emergency and prevented significant damage to the property. I have no hesitation in mending pany and giving it 5 stars.” – Elie Zekaria – November 2014
