i still have 3 pairs on the van, use these for mainly internal of commercial work but also for odd student accomodation that has been egged and for new or painted windows that need scraping, i also use them on the occasional job where wfp doesnt give a satisfactory job to me they are just another tool and i use what is best for what i am cleaning.
all my ladders are ladder taged which is a monitoring system for the ladders condition and they are always used safely ie footed or secured so HSE dont have a problem with it if my risk assessments show reasons for me using them.
