@jamespa When I contracted a company to install my solar energy system and battery, I was allocated a ‘surveyor’ to ascertain the best arrangement of panels, their positioning, the wiring runs, position of battery and means of connection to my CU and the earthing system etc. By the time it came to the installation, the surveyor had passed on the project to a ‘project manager’. It turned out the PM was a trainee, wet behind the ears and possibly straight from university. The PM’s experience was zero, her competence was through the floor and the various contractors would roll their eyes upon the mention of her name. The result was an installation that took three times longer than estimated with much equipment delivered having to be returned as unsuited to the task, roofers sitting around for three days in high temperatures doing very little waiting for supplies and work having to be re-done later. @asoksevil , if you have several or more contractors involved, please make sure you have a competent Project Manager in overall charge! Regards, Toodles.

Situation normal for the construction industry then!
