The technician that called had obviously been drinking alcohol before arrival and the bathroom and boiler room continued to smell after he left about 12 minutes after trying to identify and fix the problem. The boiler is working but when I return after being away for a few days, the reset light is flashing a fan is running continuously. I was advised to switch off the boiler at the control panel in future. This is something I have never had to do since having the boiler installed by H2 Property Services in 2008. The technician was not interested. No Stars for service.
