I'll never understand those (not implying you
@littlespark ) that don't push for installations to meet recent (if not the latest) regs is beyond me. It's like saying "I'm fine with candles, I've been safe with them for years" even though we have electricity, it's barmy.
I admit situations and circumstances tend to dictate the overall outcome but we really should be educating customers as to the benefits of the latest protection methods (AFDDs notwithstanding), especially when they've been around for decades.
