   Boiler installation. Extremely accurate pipes. I am thinking I don't need a board to cover them as it was before :) Great communication, professional approach. Also the engineer left the work area clean and disposed all the trash. Highly recommended.

   Excellent service. Armand arrived on time, quickly diagnosed the fault (error code E133 ignition fault on the boiler), explained the issue clearly, and had the boiler up and running efficiently. Professional, knowledgeable and reasonably priced. Highly recommended!
