I live in the UK and used to be an electrician. What you say is for the most part true; on any commercial or industrial site or construction project, the building or site manager is going to come down hard on you if you're not using appropriate PPE. It's a liability and ass-covering thing: if you get injured (or indeed killed), even if it's entirely your fault and would have been avoided by using PPE, the manager is liable, and HSE will bury them. They know this, and they will expel you from the site if you don't comply.

That said, it's all a wash in residential. I've seen plenty of plumbers and heating engineers drilling walls without any eye or ear protection. I've seen plenty of heating engineers soldering copper pipes without a mask and in poor ventilation (e.g. tight cupboards). I've even seen other electricians installing meter tails into a live supply without any gloves, standing on conductive surfaces like surface drainage grates.
