Most of the scaffolds on this type of show,Grand Designs,Sarah Beeny ,DIY SOS ect. all seem to feature rubbish scaffolds,not all the time.Some obviously put up by the builders,some by "proper scaffs".Surely if your firm is going to be on national TV you would put up the best job ever.Now some jobs are spot on but they are sadly in the minority.On that last Grand Designs the two of them where standing on beams ,about 40ft up on the roof,no handrails or netting all on national TV.They mustn't have any safety advisers on the show.
