Yas has very competitive rate, and he did everything he said he would do. With great communication, he's very friendly and easy to talk to.
He turned up 30mins late, then left us for almost an hour, therefore completely missed out the gas off window, which we pre-arranged with the building manager 2 days in advance and told him about it repeatedly. He was then late over 30mins the second visit. Luckily we booked the gas-off window 30mins later than his promised arrival time.
The work was nicely done, apart from the fact that he connected the hot water to the cold side and verse visa. (However, the writing on the tap ware is not extremely visible.)
We are just happy that it's all done. He supplied certificate for the gas connection, too. Thank you.
