Armand the plumber was very professional, and I had my gas safety check and my boiler checked in time. Armand was also able to respond to all my questions. So it is a 5 star's evaluation for me.

 Trustindex verifies that the original source of the review is Google. Rapid response from Armand to a Google Local Services request. Good comms via WhatsApp. Same day attendance. I live in a tricky area for parking but Armand managed that without complaint. Quickly diagnosed and resolved the problem with my heating system, made efficiency improvements, and taught me a few things along the way for future reference. The following morning I had a worsening situation due to air and pressure changes settling in the system overnight (unavoidable) but Armand was responding to my messages from 6:51am and helping me to relay instructions to my tenant in real time to apply a final fix. The heating system is now working incredibly effectively and efficiently. I'm burning hardly any gas to keep the property warm. Gas bill reducing substantially now. As with everything these days, skilled people don't come cheap; you get what you pay for and I would recommend Armand to others.

 Trustindex verifies that the original source of the review is Yell. Armand arrived the same morning as I called, keeping me informed as to his expected arrival time. He was very efficient at sorting the problem, which was stopped a leaking pipe. He wore a medical mask and gloves , and was very aware of social distancing and of not touching surfaces unnecessarily, enabling my lodger to remain safely at work in the same room whilst he was there. He is very polite and friendly and gives a clear explanation of what needs doing. He is my go-to person whenever I need a plumber, having been here three times now, and I highly recommend him .
