Doing subby installs the now, gaffer asks us to do him a favour and go to a flat that had been fitted out, but the gas meter hadn't went in before the install.It was supposed to be fitted on the same day. So we were to connect onto the meter and commission the boiler. Connect the gas, get fired up, my mate starts filling out the CP12. Open the MI's to fill out the benchmark to find the installer had already filled it out!! Completely!! We're fitting WB 28i's.... His gas rates were 3m for both CH and HW! If you're gonna lie at least make it believable mate!! Thinking he must get the same reading for every install eh??
