I have known Cosmin for 5+ years. He has done all the plumbing/heating (including moving the kitchen pipework from one room to another, 2 brand new bathrooms, installing underfloor heating/new boiler/all radiators). He is very professional, trustworthy and also friendly. He has always been available at short notice and willing to help for any follow up tasks and when issues have occurred (e.g. a leak from the flat above ours). I have most recently used him for redecoration. He's been very flexible and accommodating (a real can do attitude). It's always a pleasure working with him and his team. - Anne

Construction on Site came to us via recommendation. Our request was an awkward one as it was to pick up and remedy the work of a previous shoddy builder. Having assessed the previous works and the remedial works required, Cosmin and his team just got on without fuss and did what was needed, working quickly, tidily and to schedule, enabling us to get our build back on track. What a fantastic team we have found here and who we hope to bring back to help with next stages. Highly recommend without hesitation. - Greally-Totteridge

Every task I asked for to be done was completed to a high, professional standard. Cos offered me technical advice regarding our kitchen and bathroom. He and his team worked very hard on completing the works and overall we are very happy with our new kitchen and bathroom. Very courteous and reliable people. Work was done on time with minimal disruption in our home and I could fully trust Cos that all works would be done to the highest quality. Highly recommend Cos and his team - V Johnson

Highly recommend Construction on Site Ltd. They offered a wonderful, friendly and honest service which was refreshing. We required all plumbing checked and connected, boiler to be installed and heating tested. We were informed at every stage what work was being carried out, shown any issues discovered and offered solutions to the problems. The team were professional and caring in the work carried out and I would not hesitate to use them again. - Bhavik
