I used Green Planet around Christmas 2016 to install a boiler, as our old one broke down. Brian came around between Christmas and New Year's eve to install the boiler in one afternoon. The boiler worked for one month, but then it started loosing pressure on a daily basis. We contacted Brian, and it took him roughly one week to come around and fix it. However, not even 1-2 weeks later the same issue started again. We asked again for him to come around and fix it, and it took him at least 3-4 weeks to come around and have a look. Even though he supposedly fixed it, the issue still remained. After telling him the whole situation was quite ridiculous, and that I would call for another plumber if he wasn't able to fix the issue, he came around and supposedly fix it. The boiler has not been loosing pressure for a while now (1.5 months), but I am not sure the issue has been fixed yet. I am still thinking to call another plumber to get the installation double-checked and get a second opinion. Overall experience: very bad, and I would not recommend Green Planet.
