 Trustindex verifies that the original source of the review is Google. I would like to recommend this service: it was quite easy to book and have an appointment in a short term. 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. Boiler Repair Service Review

Today I had my boiler repaired, and I am extremely satisfied with the service. From start to finish, the process was seamless. Armand the engineer was punctual, professional, and highly knowledgeable. He quickly diagnosed the issue, explained the problem in simple terms.
The repair itself was efficient, Armand ensured everything was working perfectly before leaving. He even gave me some tips on maintaining the boiler to avoid future problems.
Overall, this was a stress-free experience, and I’d highly recommend Armand and his company for any boiler repairs.

 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.
