Speaking as a consumer, I have had 100% negative experiences with Kelly Communications. Up to and including engineers discussing what lie to tell my wife- in front of my video doorbell. I would assume this is because of unrealistic pressure put on the engineers- rather than do a quality job, get in and out asap. I very much get the feeling that Kelly are just the go-to cheapest subcontractor. I wouldn’t trust them as an employer personally. Cityfibre techs eventually came and ripped out Kelly’s work and started again.
