We’ve all had it. You’re having a nice relaxing evening at home after a busy day, and then you hear it. The dreaded door knock. You think, ‘But I’m not expecting anyone’.

As you stare at them trying to look earnest, nodding and lapping up a healthy dose of second-hand apprehension and embarrassment you think to yourself, why must doorknockers exist? Power company Energy Online, which has vowed not to have doorknockers, has released an ad showing the most ideal doorknocking scenario.
