Donal did a great job for me, apart from electric shower installation, he also installed two smoke detector,HOBs, and fixed a oven switch, change several new parts for main switch. Few days later, i got someone (non-professional) to install the lights in living room, dining room, however for some reasons, after install the light in dining room,the lights in both dining room and kitchen are not working anymore that's Friday, i have to send an urgent msg to Donal for help on Sat morning as my wife and my son will back from holiday on Sunday. Donal give immediate response and come to my house in the afternoon to have the issue resolved, that's small issue for him, but for me, he did a great help for me. He has fixed drain block issue without any further charge. I will definitely to contact Donal for further related job during his professionalism.
