Drew installed our Nest thermostat within a week of us enquiring. We had a horrible situation with our boiler being installed by someone else 2 years ago who then went out of business and were aware that the job wasn't done well and potentially not even safe so were concerned he wouldn't do it. He noticed things that had not been done properly that we were already aware of and after we asked quoted us a great price to fix the issues if we wanted. He then quickly installed the Nest for us and walked us through the functionality as well as recommending setting the heating on the app not the thermostat as he had one of his own and was knowledgable on the subject. It literally is a relief to know we now have a plumber that we can trust after our previous experience!! Highly recommend!
